Unrelated-donor bone marrow transplantation for Philadelphia chromosome-positive chronic myelogenous leukemia in children.
Authors: Gamis A S , Haake R , McGlave P , Ramsay N K
Published: February 2017

PURPOSE

Bone marrow transplantation (BMT) for Philadelphia chromosome-positive (Ph1) chronic myelogenous leukemia (CML) results in a 55% to 64% disease-free survival (DFS) rate in 20% to 30% of cases with a matched-sibling donor (MSD). Studies that include primarily adults with CML, using unrelated-donor (URD) BMT, have expanded this option to those without an MSD. We review and compare the efficacy of URD and MSD BMT in children with Ph1 CML.

PATIENTS AND METHODS

Eleven children with URD BMTs were reviewed and compared with 11 children with MSD BMTs for Ph1 CML. Among the URD BMT recipients, there were three with fully matched marrows and 10 with advanced CML. The median time from diagnosis to transplant was 2.6 years. Among the MSD BMT recipients, 11 had fully matched marrows and five had advanced CML. The median time from diagnosis to BMT was 0.7 years. All received non-T-depleted marrows after cyclophosphamide and fractionated total-body irradiation.

RESULTS

Both groups had similar engraftment times. Late graft failure occurred in two URD patients. Graft-versus-host disease (GVHD), > or = grade II, was similar in both groups (77% for URD BMT, 45% for MSD BMT), although more severe acute disease and more persistent chronic disease was seen in the URD group. The Kaplan-Meier estimate of DFS was 45% +/- 15% (SE) and 78% +/- 14% (SE) in the URD and MSD groups, respectively, at 3 years. All had Karnofsky scores of more than 70%, except one URD patient debilitated from GVHD.

CONCLUSION

CML is eventually fatal to all patients without BMT. The high survival rate seen among children who receive a URD BMT, despite several adverse factors, opens this important therapeutic option to those without an MSD.
Extended triple intrathecal chemotherapy trial for prevention of CNS relapse in good-risk and poor-risk patients with B-progenitor acute lymphoblastic leukemia: a Pediatric Oncology Group study.
Authors: Pullen J , Boyett J , Shuster J , Crist W , Land V , Frankel L , Iyer R , Backstrom L , van Eys J , Harris M
Published: February 2017

PURPOSE

The Pediatric Oncology Group (POG) acute leukemia in childhood (ALinC) 13 study tested two treatment regimens that used different CNS chemoprophylaxis for children older than 12 months with non-T, non-B acute lymphoblastic leukemia (ALL) and with no demonstrable CNS disease at diagnosis.

PATIENTS AND METHODS

With the first regimen, standard (S), six injections of triple intrathecal chemotherapy (TIC), consisting of methotrexate (MTX), hydrocortisone (HC), and cytarabine (ara-C), were administered during intensification treatment and at every-8-week intervals throughout the maintenance phase for 17 additional doses. The second regimen, standard and MTX pulses (SAM), also specified six TICs during intensification, but substituted every-8-week pulses of intermediate-dose parenteral methotrexate (IDM; 1 g/m2) for the 17 maintenance TIC injections, with a low-dose intrathecal (IT) MTX boost administered with the first four maintenance IDM pulses. Otherwise, systemic therapy on regimen SAM was identical to regimen S. There were 1,152 patients randomized to the S and SAM regimens after stratification by risk group (age/leukocyte count) and immunophenotype.

RESULTS

The 5-year probabilities (+/- SE) of an isolated CNS relapse were regimen S: good risk (n = 381), 2.8% +/- 1.3%; poor risk (n = 196), 7.7% +/- 3.2%; good + poor risk (n = 577), 4.7% +/- 1.5%; regimen SAM: good risk (n = 388), 9.6% +/- 2.2%; poor risk (n = 187), 12.7% +/- 4.2%; good + poor risk (n = 575), 10.9% +/- 2.2%. In poor-risk patients, approximately one third of the isolated CNS relapses occurred before preventive CNS therapy was begun at week 9. Hence, regimen S has provided better CNS preventive therapy for both good- and poor-risk patients (P < .001 overall). The difference is statistically significant for good-risk patients (P < .001), but not for poor-risk patients (P = .20). Neither treatment has shown a significant advantage in terms of general outcome.

CONCLUSION

TIC injections extended throughout the intensification and maintenance periods are superior to IDM pulses for prevention of CNS leukemia. Our results with TIC seem comparable with those achieved with other contemporary methods of CNS preventative therapy. Thus, extended TIC affords a reasonable alternative to CNS irradiation plus upfront IT MTX for patients with B-progenitor ALL.
Carboplatin and vincristine for recurrent and newly diagnosed low-grade gliomas of childhood.
Authors: Packer R J , Lange B , Ater J , Nicholson H S , Allen J , Walker R , Prados M , Jakacki R , Reaman G , Needles M N
Published: February 2017

PURPOSE

This study investigates the response rate to and toxicity of carboplatin and vincristine in children with recurrent low-grade gliomas (LGGs) or patients younger than 60 months with newly diagnosed LGGs.

PATIENTS AND METHODS

Twenty-three children with recurrent and 37 children with newly diagnosed LGGs were treated with a 10-week induction cycle of carboplatin and vincristine, followed by maintenance treatment with the same drugs. Patients were evaluated for response to treatment and toxicity.

RESULTS

Twelve of 23 (52% +/- 10%; 95% confidence interval [CI], 0.32 to 0.72) assessable children with recurrent disease had an objective response to treatment, which included a greater than 50% reduction in tumor size in seven of 23 (30% +/- 10%; 95% CI, 0.10 to 0.50). Twenty-three of 37 (62% +/- .08; 95% CI, 0.46 to 0.78) of newly diagnosed patients had an objective response, 16 of 37 (43% +/- 0.08%; 95% CI, 0.27 to 0.59) with greater than 50% reduction in tumor size. The majority of those with an objective response had diencephalic tumors (n = 29), but children with thalamic (n = 2), cortical (n = 1), and brain stem (n = 2) LGGs also responded to treatment. Of the 35 patients with objective response to treatment, the maximum response was seen in 25 after completion of induction and in the remaining 10 after two to six cycles of maintenance treatment. Forty-nine of 53 (92% +/- .04%) patients who were stable or improved after induction remain without progressive disease (PD). Hematologic toxicity was common, but resulted in cessation of therapy in only one patient. Six children have been removed from the study because of allergic reactions, which were considered to be carboplatin-associated.

CONCLUSION

Carboplatin and vincristine have activity in children with recurrent and newly diagnosed progressive LGGs. Objective responses to treatment after chemotherapy can be seen. This drug regimen is relatively well tolerated, and further studies are indicated to define the role of this combination of drugs in children with newly diagnosed LGGs.
Alternating chemotherapy and twice-daily thoracic radiotherapy in limited-stage small-cell lung cancer: a pilot study of the Eastern Cooperative Oncology Group.
Authors: Johnson D H , Turrisi A T , Chang A Y , Blum R , Bonomi P , Ettinger D , Wagner H
Published: February 2017

PURPOSE

This pilot study was undertaken to determine the efficacy and feasibility of alternating cisplatin and etoposide with multiple daily fractions of thoracic radiotherapy (TRT) in patients with limited-stage small-cell lung cancer (SCLC).

PATIENTS AND METHODS

Thirty-four SCLC patients received four courses of cisplatin (30 mg/m2/d x 3) plus etoposide (120 mg/m2/d x 3) (PE) every 3 weeks. TRT was administered twice daily (1.5 Gy per fraction) for 5 consecutive days in the week after cycles 1, 2, and 3 of chemotherapy (total TRT dose, 45 Gy). Patients who achieved a complete response (CR) received one course of late-intensification (LI) treatment consisting of cyclophosphamide (4 g/m2) and etoposide (900 mg/m2). Prophylactic cranial irradiation (PCI) was optional.

RESULTS

Nineteen of 32 assessable patients achieved a CR (59%) and 12 had a partial response (38%), for an overall response rate of 97% (95% confidence interval [CI], 84% to 99%). Median survival was 18 months, while 2-year progression-free survival was 47%. Leukopenia < or = 1,000/microL occurred in 12% of induction treatment cycles. Severe esophagitis was uncommon. Pulmonary fibrosis that was asymptomatic or minimally symptomatic was observed in eight patients (25%). There was one episode of adult respiratory distress syndrome (ARDS) during LI chemotherapy. Life-threatening neutropenia (< or = 500/microL) developed in all patients who underwent LI chemotherapy, with a median duration of 10 days (range, 8 to 19). Two patients died of sepsis during LI chemotherapy.

CONCLUSION

Alternating PE and TRT as performed in this trial is an effective brief induction regimen for limited-stage SCLC. However, this particular regimen did not appear to be substantially different in terms of efficacy or toxicity compared with regimens using concurrent chemotherapy and standard-fraction TRT. LI chemotherapy was associated with unacceptable toxicity and did not appear to have a favorable impact on survival.
Prognostic value of PS2 and cathepsin D in 710 human primary breast tumors: multivariate analysis.
Authors: Foekens J A , van Putten W L , Portengen H , de Koning H Y , Thirion B , Alexieva-Figusch J , Klijn J G
Published: February 2017

PURPOSE

Evaluation of the prognostic value of cytosolic PS2 (pS2 protein) and cathepsin D in a large series of breast cancer patients by multivariate analysis taking into account steroid receptors and conventional prognostic factors.

PATIENTS AND METHODS

Prognostic factors were analyzed in 710 primary breast cancers (median follow-up, 4 years). PS2 and cathepsin D were measured by radiometric immunoassays. Estrogen receptor (ER) and progesterone receptor (PgR) status were assessed by radioligand binding assays and multiple-point Scatchard analysis.

RESULTS

The best cutoff point for PS2 to discriminate between positive (61% of the tumors) and negative was 2 ng/mg protein (univariate P value in 5-year relapse-free survival = .003). For cathepsin D, no sensible cutoff point could be chosen, since there was a continuous association between the level of cathepsin D and relapse rate (P = .001). In Cox multivariate analysis, relapse rate decreased with age of premenopausal/perimenopausal patients and with PS2 or steroid receptor positivity, and increased with the size of the tumor, the number of positive lymph nodes, and increasing levels of cathepsin D. In analysis for overall survival, age of both premenopausal/perimenopausal and postmenopausal patients, tumor size, the number of positive lymph nodes, ER/PgR, and PS2 were all independently associated with the rate of death. The level of cathepsin D was positively correlated with the rate of death, but this trend was not statistically significant. Separate Cox multivariate analyses for relapse-free survival in subgroups of patients as defined by nodal status showed that the contribution of PS2 and cathepsin D was the strongest in the node-negative subgroup. Node-negative patients with tumors containing PS2 values < or = 2 ng/mg protein and cathepsin D values more than 70 pmol/mg protein experienced a 4.5-fold increase in relapse rate as compared with those with PS2 levels greater than 2 ng/mg protein and cathepsin D levels < or = 30 pmol/mg protein.

CONCLUSION

PS2 and cathepsin D are independent prognostic factors in primary breast cancer and lymph node-negative patients.
Phase II study of CPT-11, a new camptothecin derivative, in metastatic colorectal cancer. CPT-11 Gastrointestinal Cancer Study Group.
Authors: Shimada Y , Yoshino M , Wakui A , Nakao I , Futatsuki K , Sakata Y , Kambe M , Taguchi T , Ogawa N
Published: February 2017

PURPOSE

A phase II study was conducted to evaluate the antitumor effect and toxicity of CPT-11 in patients with metastatic colorectal cancer.

PATIENTS AND METHODS

From December 1989 to March 1991, 67 patients with metastatic colorectal cancer were enrolled in this study. Sixty-three patients were assessable for toxicity and response. Their median age was 57 years (range, 24 to 72). Forty-six patients (73%) had a good performance status of 0 or 1. Fifty-one patients (81%) had received prior chemotherapy. The major sites of metastasis were liver (63%) and lung (44%). CPT-11 was administered as a 100 mg/m2 weekly intravenous infusion, or as 150 mg/m2 every 2 weeks. The dose was reduced based on the grade of leukopenia and diarrhea, if necessary.

RESULTS

A partial response was obtained in 17 of 63 assessable patients (27%; 95% confidence interval, 16% to 38%). The response rate in patients with prior radiotherapy or chemotherapy was 25% (13 of 52). Liver metastases showed a 15% (six of 40) response and lung metastases showed a 39% (11 of 28) response. The median duration of partial response was 127 days (range, 49 to 353) and the median overall duration of response was 208 days (range, 99 to 381). The major toxicities (> or = grade 3) were leukopenia (16%), diarrhea (13%), nausea and vomiting (13%), and alopecia (11%). Adverse effects were generally well tolerated and reversible. Treatment could be continued on an outpatient basis for patients without severe toxicity. Hemorrhagic cystitis was not encountered in this study.

CONCLUSION

CPT-11 showed promising antitumor activity against metastatic colorectal cancer that was resistant to prior therapy. Further clinical trials of combination chemotherapy using CPT-11 are justified.
Autologous bone marrow transplantation in poor-prognosis intermediate-grade and high-grade B-cell non-Hodgkin's lymphoma in first remission: a pilot study.
Authors: Freedman A S , Takvorian T , Neuberg D , Mauch P , Rabinowe S N , Anderson K C , Soiffer R J , Spector N , Grossbard M , Robertson M J
Published: February 2017

PURPOSE

Using high-dose therapy and autologous bone marrow transplantation (ABMT) to overcome cellular resistance and eradicate minimal disease, we initiated a pilot study during first remission in patients with non-Hodgkin's lymphoma (NHL) to examine whether the long-term disease-free survival (DFS) rate can be improved for patients with poor-prognosis intermediate/high-grade NHL.

PATIENTS AND METHODS

Twenty-six patients with advanced-stage diffuse intermediate/high-grade B-cell NHL (including 16 patients with diffuse small cleaved-cell [DSC]) were selected at presentation by histologic and clinical characteristics to have less than a 25% probability of long-term DFS with conventional treatment. After induction chemotherapy, 16 patients were in complete remission (CR) and 10 were in a minimal disease state. Patients were then treated with high-dose cyclophosphamide, total-body irradiation (TBI), and anti-B-cell monoclonal antibody-purged ABMT.

RESULTS

Following ABMT, no acute in-hospital treatment deaths occurred, and engraftment of granulocytes and platelets was significantly faster than for patients undergoing ABMT who were in second or subsequent remission. Of 26 patients, 21 remain in CR maintained without continued therapy, three relapsed in sites of prior nodal disease (4.8, 5.4, and 28 months post-ABMT), and two died in remission. The DFS rate is estimated to be 85% at 28 months and thereafter. The median follow-up period for the 21 patients who are alive and disease-free is 32 months.

CONCLUSION

This pilot study suggests that consolidation of first remission with ABMT may improve the long-term DFS rate for diffuse intermediate/high-grade NHL patients at high risk for relapse.
Dose-ranging study of oxycodone for chronic pain in advanced cancer.
Authors: Glare P A , Walsh T D
Published: February 2017

PURPOSE AND METHODS

We assessed the analgesic efficacy and safety of single-entity oxycodone solution at doses greater than 10 mg orally every 4 hours in 24 patients with chronic cancer pain not controlled by weaker analgesics.

RESULTS

Twenty of 24 patients completed the study. Pain relief was obtained with doses up to 60 mg every 4 hours. When oxycodone was taken for long periods, further dose increments could be made safely. The side effects of oxycodone are mild, and common to all opioids, with sedation and constipation most frequent. Nausea was more common in females in all age groups and in patients of either sex less than 50 years of age. Episodes of serious toxicity were rare, and responded to dose reduction. Patients older than 65 years required lower doses, suggesting pharmacokinetic similarities between oxycodone and morphine. Patients changed from oral oxycodone to morphine remained pain-free when relative milligram potency ratios of 1:1 to oral morphine and 3:1 to intravenous morphine were used.

CONCLUSION

Oxycodone has been shown for the first time to be as versatile and flexible as oral morphine in the management of chronic pain in patients with advanced cancer.
Cardiac dysfunction following spinal irradiation during childhood.
Authors: Jakacki R I , Goldwein J W , Larsen R L , Barber G , Silber J H
Published: February 2017

PURPOSE

Although spinal irradiation used in the treatment of CNS malignancies includes a portion of the heart in the radiation field, cardiac effects have not been previously reported.

PATIENTS AND METHODS

We compared patients treated for malignancy in childhood with spinal irradiation (n = 26) with patients treated with mediastinal/flank irradiation (n = 47) that included the heart in the radiation field. All patients were more than 1 year from completion of radiation therapy. Patients underwent at least two of the following cardiac evaluations: (1) ECG; (2) 24-hour ambulatory ECG; (3) echocardiogram; and (4) exercise-testing using cycle ergometry.

RESULTS

Twelve of 16 patients (75%) in the spinal irradiation group with an assessable exercise test achieved a maximal cardiac index (MCI) below the fifth percentile as compared with 13 of 40 patients (32%) who had received mediastinal/flank irradiation (P = .007). Furthermore, after adjusting for normal heart growth, radiation and anthracycline doses, and follow-up time, the group of patients who received spinal irradiation had significantly higher estimated posterior wall stress (P = .002), expressed as the natural logarithm of the ratio of end-diastolic left ventricular internal diameter (LVID) to left ventricular posterior wall thickness (LVPWT), than the group who had received mediastinal/flank irradiation. Finally, eight of 26 patients (31%) in the spinal group had pathologic Q-waves in the inferior leads versus three of 47 (6.4%) in the mediastinal/flank group (P = .001).

CONCLUSION

Patients who have received spinal irradiation for pediatric malignancies appear to be at risk for significant cardiac dysfunction. The asymmetric distribution of radiation to a growing heart, as given with spinal irradiation, may be the cause of these findings.
Effect of prior interferon alfa therapy on the outcome of allogeneic bone marrow transplantation for chronic myelogenous leukemia.
Authors: Giralt S A , Kantarjian H M , Talpaz M , Rios M B , Del Giglio A , Andersson B S , Przepiorka D , Deisseroth A B , Champlin R E
Published: February 2017

PURPOSE

To determine whether prior interferon alfa (IFN-A) treatment affects the outcome of allogeneic bone marrow transplantation.

PATIENTS AND METHODS

We analyzed the outcome of 77 patients with chronic myelogenous leukemia (CML) who received transplants from an HLA-identical donor using a total-body irradiation-containing preparative regimen. Engraftment, acute and chronic graft-versus-host disease (GVHD), survival, and disease-free survival were compared between patients who had previously received interferon (IFN+) to those who had not (IFN-). Forty-one patients were transplanted in chronic phase and 36 had more advanced CML. The IFN+ group had received IFN-A in doses of 3 to 5 x 10(6) U/m2 three times a week or more for at least 4 weeks anytime before transplantation.

RESULTS

For patients in chronic phase, there were no significant differences between the IFN+ group and the IFN- group in regard to neutrophils recovery more than 1.0 x 10(9)/L (29 v 24), platelet recovery more than 50 x 10(9)/L (33 v 36), incidence of grade II to IV GVHD (23% v 28%), incidence of chronic GVHD (39% v 47%), disease-free survival (46% +/- 11% v 59% +/- 13%), relapse (9% v 11%), or 100-day transplant-related mortality (22% v 16%). In patients with more advanced stage disease, there was also no significant differences between the IFN+ group and the IFN- group in regard to these outcomes.

CONCLUSION

Prior treatment with IFN-A did not adversely affect transplant outcome. Further studies are required to better understand the complementary roles of IFN-A and allogeneic bone marrow transplantation for the treatment of CML.
Infusional cyclophosphamide, doxorubicin, and etoposide in relapsed and resistant non-Hodgkin's lymphoma: evidence for a schedule-dependent effect favoring infusional administration of chemotherapy.
Authors: Sparano J A , Wiernik P H , Leaf A , Dutcher J P
Published: February 2017

PURPOSE

This study attempted to determine the efficacy of cyclophosphamide (C), doxorubicin (D), and etoposide (E) administered as a continuous intravenous (IV) infusion (infusional CDE) over 4 days in patients with relapsed or resistant non-Hodgkin's lymphoma (rNHL) and in patients with previously untreated (uNHL) who had poor prognostic features.

PATIENTS AND METHODS

Fifty-eight patients with rNHL and 10 patients with uNHL received infusional CDE every 28 or more days; all but one had intermediate- to high-grade histology. The cumulative doses of C, D, and E administered per treatment cycle were 750 mg/m2, 50 mg/m2, and 240 mg/m2, respectively. In the rNHL group, all patients had previously received C, most (81%) had received D, and a minority (16%) had received E.

RESULTS

Objective response occurred in 30 patients with rNHL (52%; 95% confidence interval, 39% to 65%); 10 patients had a complete response (CR) (17%; 95% confidence interval, 7% to 27%). Eleven patients (19%) remain progression-free (median follow-up, 22 months; range, 10+ to 38+), and six patients (10%) are disease-free (median follow-up, 25 months; range, 10+ to 38+). Among 10 patients with uNHL, eight (80%) had a CR, and none have relapsed (median follow-up, 11 months; range, 9+ to 24+). Toxicity was primarily hematologic. Two treatment-related deaths (3%) occurred, both attributable to infection in the relapsed or resistant group.

CONCLUSION

Infusional CDE produced a CR in substantial proportion of patients who had previously been exposed to at least two of the agents administered as an IV bolus, suggesting a schedule-dependent effect in favor of the infusional administration of certain cytotoxic agents in patients with lymphoid neoplasms. In addition, infusional CDE was effective and tolerable in patients with poor-prognosis NHL when used as initial therapy, and merits further study in that setting.
Preoperative chemoradiation followed by transhiatal esophagectomy for carcinoma of the esophagus: final report.
Authors: Forastiere A A , Orringer M B , Perez-Tamayo C , Urba S G , Zahurak M
Published: February 2017

PURPOSE

In 1990 we published the results of an intensive 3-week preoperative chemoradiation regimen for locoregional esophageal cancer that suggested improved survival compared with historical controls. We now report the long-term results at a median follow-up of 78.7 months.

PATIENTS AND METHODS

Forty-three patients with locoregional squamous cell carcinoma or adenocarcinoma of the esophagus or cardia were treated with fluorouracil (5-FU), cisplatin, and bolus vinblastine concurrent with radiation administered over 21 days. Transhiatal esophagectomy was performed on day 42.

RESULTS

Forty-one patients (95%) completed the preoperative treatment, and 36 (84%) had a potentially curative resection. Ten of 41 (24%) had no tumor in the resected esophagus and nodal tissues (path-negative group). The median survival duration of all 43 patients registered on study was 29 months; 34% were alive at 5 years. By histology, median survival durations were 32 months for 21 adenocarcinoma patients and 23 months for 22 squamous cell patients, with corresponding 5-year survival rates of 34% and 31%, respectively. Analysis of the 36 patients who underwent a potentially curative resection demonstrated median survival durations of 32 and 44 months and 5-year survival rates of 36% and 43%, respectively, for adenocarcinoma and squamous cell histologies. Path-negative (complete response [CR]) patients had a median survival duration of 70 months and 60% were alive at 5 years, while those patients with residual tumor in the resected esophagus had a median survival duration of 26 months and 32% were alive at 5 years (P = .114 by the log-rank test and P = .04 by the Wilcoxon test).

CONCLUSION

The results of this regimen appear improved over those reported with surgery alone, with an approximate doubling of the 5-year survival rate. Thirty-two percent of patients with residual tumor in the esophageal specimen are long-term survivors, which suggests a benefit from esophagectomy. A randomized trial is in progress to compare this preoperative regimen with immediate surgery.
Alternating combination VCMP/VBAP chemotherapy versus melphalan/prednisone in the treatment of multiple myeloma: a randomized multicentric study of 487 patients.
Authors: Bladé J , San Miguel J F , Alcalá A , Maldonado J , Sanz M A , García-Conde J , Moro M J , Alonso C , Besalduch J , Zubizarreta A
Published: February 2017

PURPOSE

To determine whether combination chemotherapy with alternating cycles of vincristine, cyclophosphamide, melphalan, and prednisone (VCMP) and vincristine, carmustine (BCNU), Adriamycin (doxorubicin; Farmitalia, Carlo-Erba Laboratories, Spain), and prednisone (VBAP) is better than the standard melphalan-prednisone (MP) regimen in multiple myeloma (MM).

PATIENTS AND METHODS

From January 1985 to December 1989, 28 institutions of the Spanish Cooperative Group for Hematological Malignancies Treatment, Spanish Society of Hematology (PETHEMA) entered 487 eligible patients with symptomatic MM into the study. Patients were randomized to receive either MP or alternating courses of VCMP and VBAP. Logistic regression and the Cox proportional hazards models were used to assess the association between patients' characteristics and response rate and survival, respectively.

RESULTS

Among 449 patients who were assessable for response, the overall response rate to MP was 51.8% (31.5% objective response plus 20.3% partial response) as compared with 62.7% (45.2% objective response plus 17.5% partial response) to VCMP/VBAP (P = .025). Also, a significantly higher proportion of objective responses was observed with combination chemotherapy (45.2% v 31.5%; P = .004). The factors associated with an unfavorable response rate in the overall series were low platelet count, treatment with MP, high creatinine level and immunoglobulin, (IgG) monoclonal (M)-component. No significant differences were found when survival rates of both groups of patients were compared. However, patients with IgA myeloma treated with VCMP/VBAP survived significantly longer than those who received MP (median, 20.2 v 38.4 months; P < .005).

CONCLUSION

These results indicate that combination chemotherapy improves response rate in MM. However, this does not result in a significantly different survival rate, except for patients with IgA myeloma, who survive significantly longer with combination chemotherapy.
Combination chemotherapy with or without thoracic radiotherapy in limited-stage small-cell lung cancer: a randomized trial of the Southeastern Cancer Study Group.
Authors: Johnson D H , Bass D , Einhorn L H , Crawford J , Perez C A , Bartolucci A , Omura G A , Greco F A
Published: February 2017

PURPOSE

The primary objective of this randomized prospective study was to compare the survival of limited-stage small-cell lung cancer (SCLC) patients treated with chemotherapy alone or chemotherapy plus thoracic radiotherapy (TRT). A secondary objective was to determine the effect of consolidation chemotherapy on survival.

PATIENTS AND METHODS

This multiinstitutional phase III study included 386 patients with limited-stage SCLC. All patients received cyclophosphamide 1,000 mg/m2, doxorubicin 40 mg/m2, and vincristine 1 mg/m2 (CAV) every 3 weeks for six cycles. Irradiated patients received 30 Gy in 10 fractions during weeks 1 and 2 of chemotherapy. Fifteen Gy in five fractions was administered during week 7 (total dose, 45 Gy). Following CAV, responding patients were randomized to receive two cycles of consolidation chemotherapy (cisplatin 20 mg/m2/d for 4 days plus etoposide 100 mg/m2/d for 4 days) or observation.

RESULTS

Complete (46% and 38%; P = .14) and overall response rates (67% and 64%; P = .58) were not statistically significantly different. Although not significantly different, median (14.4 v 12.8 months) and 2-year survival (33% v 23.5%) rates favored the irradiated patients. Grade 4 hematologic toxicity was greater in irradiated patients (60% and 39%; P < .001). Patients given consolidation chemotherapy experienced superior median (21.1 v 13.2 months; P = .028) and 2-year survival (44% v 26%; P = .028) rates.

CONCLUSION

The concurrent use of TRT and CAV chemotherapy as administered in this study failed to improve the survival of limited-stage SCLC patients compared with CAV alone. Life-threatening hematologic toxicities were more frequent with combined-modality therapy. The survival of limited-stage patients treated with CAV (with or without TRT) was improved with two cycles of cisplatin and etoposide consolidation therapy. Whether similar survival results could be achieved with cisplatin and etoposide alone requires additional study.

Published: February 2017

PURPOSE

The present study investigates the role of short chemotherapy (five cycles) versus prolonged (12 cycles) chemotherapy in small-cell lung cancer (SCLC).

PATIENTS AND METHODS

Six hundred eighty-seven patients with SCLC were registered in a multicenter study to receive five cycles of chemotherapy consisting of cyclophosphamide 1 g/m2 on day 1, doxorubicin 45 mg/m2 on day 1, and etoposide 100 mg/m2 on days 1, 3 and 5 (CDE), every 3 weeks. Four hundred thirty-four nonprogressing patients after five cycles of chemotherapy were randomized either to receive seven further cycles of the same chemotherapy or to follow-up.

RESULTS

The response rate of 585 assessable patients was 79%, with 36% attaining a complete response. Toxicity was mainly hematologic, with 16 toxic deaths (2.4% of all eligible patients), 13 of which were due to sepsis. Median survival time from registration of all patients was 326 days (396 and 267 days for limited and extensive disease, respectively) with 3.2% of patients alive at 5 years. No difference in survival between the two arms was observed, with the same number of 5-year survivors in both arms. The patients randomized to the maintenance arm had a progression-free survival (PFS) duration approximately 2 months longer than the patients randomized to follow-up (median of 177 days v 114 days from randomization; P = .0004). Among patients with a partial response who were randomized to receive maintenance chemotherapy, 12 achieved a complete response after 12 cycles. More patients in the follow-up arm than in the maintenance arm received subsequent treatment on progression and responded more frequently to that treatment. Twelve patients developed second malignancies (seven non-small-cell lung cancers).

CONCLUSION

Prolonged chemotherapy does not offer a better chance of cure than short chemotherapy (five cycles) and does not prolong survival in patients with SCLC. Short, combination chemotherapy appears to be a reasonable choice for standard treatment of SCLC and for attempts to improve the cure rate of this disease.

PURPOSE

This three-armed phase III study in adults with advanced soft tissue sarcomas was planned as a comparison of objective regression rates, toxicity, and survival of patients receiving doxorubicin alone, ifosfamide plus doxorubicin, and mitomycin plus doxorubicin plus cisplatin.

PATIENTS AND METHODS

Between December 1987 and July 1990, 279 patients with histologically confirmed sarcomas were enrolled to receive treatment A (doxorubicin 80 mg/m2), treatment B (ifosfamide 7.5 g/m2 plus doxorubicin 60 mg/m2), or treatment C (mitomycin 8 mg/m2 plus doxorubicin 40 mg/m2 plus cisplatin 60 mg/m2).

RESULTS

Of 262 assessable patients, 74 (29%) achieved objective tumor regression. Objective regression occurred in 20% of the 90 patients who received doxorubicin alone (complete remission [CR] rate, 2%), in 34% of the 88 who received ifosfamide plus doxorubicin (CR rate, 3%), and in 32% of the 84 who received mitomycin plus doxorubicin plus cisplatin (CR rate, 7%). With grade 3 or greater myelosuppression in 53% of group A, 80% of group B, and 55% of group C, regimen B was significantly more myelosuppressive than either regimen A or C (P = .01) with two, three, and one treatment-related deaths, respectively. Synovial sarcomas were responsive to ifosfamide plus doxorubicin, especially among patients younger than 40 years of age.

CONCLUSION

Ifosfamide plus doxorubicin produced a significantly higher regression rate (P = .03) than did doxorubicin alone; however, this was achieved at a level of myelosuppression significantly more intense than that produced by the single agent or by the three-drug combination. Mitomycin, doxorubicin, and cisplatin also appeared to be more active than the single agent; however, at a myelosuppression level similar to that of doxorubicin alone, this trend (P = .07) did not attain the usual level for significance. No significant survival differences were observed.
Magnetic resonance imaging in the staging of solitary plasmacytoma of bone.
Authors: Moulopoulos L A , Dimopoulos M A , Weber D , Fuller L , Libshitz H I , Alexanian R
Published: February 2017

PURPOSE

To assess prospectively the role of magnetic resonance (MR) imaging in the staging of patients with a solitary bone plasmacytoma (SBP).

PATIENTS AND METHODS

Twelve consecutive patients with an apparent SBP underwent MR imaging of both the primary tumor and the thoracic and lumbosacral spine to seek additional foci of marrow involvement that might have been undetected by standard skeletal survey. All patients received megavoltage irradiation (total dose, 40 Gy) to the primary lesion.

RESULTS

MR imaging of the thoracic and lumbosacral spine showed additional foci of marrow replacement in four of 12 patients, with signal characteristics identical to those of the primary tumor. In all four patients, the abnormal protein persisted at greater than 50% of the pretreatment value following radiation treatment. In contrast, the myeloma protein disappeared or was reduced by greater than 50% in five of the six patients with secretory disease and without additional marrow abnormalities. One of four patients progressed to multiple myeloma 10 months after diagnosis with new lesions on conventional radiographs in the same areas as detected previously by MR imaging.

CONCLUSION

Four of 12 patients considered to have a SBP by standard criteria may have been understaged, because MR imaging showed additional marrow abnormalities consistent with myeloma. MR imaging of the spine may contribute to the initial staging of SBP, especially since some patients may be cured with radiotherapy.
High-dose cyclophosphamide, carmustine, and etoposide followed by autologous bone marrow transplantation in patients with lymphoid malignancies who have received dose-limiting radiation therapy.

Published: February 2017

PURPOSE

To evaluate high-dose chemotherapy followed by autologous bone marrow transplantation (ABMT) in patients with lymphoid malignancy who had received prior radiation therapy.

PATIENTS AND METHODS

Fifty-seven patients with non-Hodgkin's lymphoma (NHL; n = 23), Hodgkin's disease (HD, n = 32), or acute lymphoblastic leukemia (ALL; n = 2) with a history of previous radiation therapy were treated with cyclophosphamide (Cy; 7.2 g/m2), carmustine (300 mg/m2 or 600 mg/m2), and etoposide (2,400 mg/m2) (CBV) followed by ABMT.

RESULTS

The projected 2-year probabilities of survival, event-free survival (EFS), and relapse were .31, .24, and .76, respectively. For patients with intermediate- and high-grade lymphoma and HD the probabilities were .27, .10, and .14 for EFS and .57, .90, and .77 for relapse. The probability of nonrelapse mortality in the first 100 days post-ABMT was 33%. Idiopathic pneumonia syndrome (IPS) was observed in no patients who received carmustine 300 mg/m2 and 23% of patients who received carmustine 600 mg/m2 (P = .05). Eight-three percent of patients who received mediastinal radiation therapy less than 3 months before transplant developed IPS, compared with 13% who received radiation therapy more than 3 months before transplant (P = .001).

CONCLUSION

ABMT following high-dose CBV resulted in long-term disease-free survival in 25% of patients with lymphoid malignancies who had previously received dose-limiting radiation therapy. Fatal IPS and a high relapse rate were major factors limiting successful outcome following ABMT. The morbidity and mortality rates associated with the administration of carmustine 600 mg/m2 were prohibitively high, especially in patients who received mediastinal radiation immediately before ABMT, and were not associated with a decrease in post-ABMT relapse.
Revisions of the international criteria for neuroblastoma diagnosis, staging, and response to treatment.

Published: February 2017

PURPOSE AND METHODS: Based on preliminary experience, there was a need for modifications and clarifications in the International Neuroblastoma Staging System (INSS) and International Neuroblastoma Response Criteria (INRC). In 1988, a proposal was made to establish an internationally accepted staging system for neuroblastoma, as well as consistent criteria for confirming the diagnosis and determining response to therapy (Brodeur GM, et al: J Clin Oncol 6:1874-1881, 1988). A meeting was held to review experience with the INSS and INRC and to revise or clarify the language and intent of the originally proposed criteria. Substantial changes included a redefinition of the midline, restrictions on age and bone marrow involvement for stage 4S, and the recommendation that meta-iodobenzylguanidine (MIBG) scanning be implemented for evaluating the extent of disease. Other modifications and clarifications of the INSS and INRC are presented. In addition, the criteria for the diagnosis of neuroblastoma were modified. Finally, proposals were made for the development of risk groups that incorporate both clinical and biologic features in the prediction of prognosis. The biologic features that were deemed important to evaluate prospectively included serum ferritin, neuron-specific enolase (NSE), and lactic dehydrogenase (LDH); tumor histology; tumor-cell DNA content; assessment of N-myc copy number; assessment of 1p deletion by cytogenetic or molecular methods; and TRK-A expression. RESULTS AND CONCLUSION: Modifications of the INSS and INRC made at this conference are presented. In addition, proposals are made for future modifications in these criteria and for the development of International Neuroblastoma Risk Groups.
OVX1 radioimmunoassay complements CA-125 for predicting the presence of residual ovarian carcinoma at second-look surgical surveillance procedures.

Published: February 2017

PURPOSE

At second-look surgical surveillance procedures, normal CA-125 levels can be associated with persistent disease in 50% to 60% of patients. A novel radioimmunoassay (RIA) has been evaluated for the ability to identify patients with persistent disease who have normal levels of CA-125.

MATERIALS AND METHODS

The OVX1 double-determinant assay used a murine monoclonal antibody to detect an epitope on a high-molecular weight mucin-like glycoprotein.

RESULTS

Apparently healthy individuals had serum OVX1 levels of 2.23 +/- 2.48 U/mL (mean +/- SD). Elevated serum OVX1 levels (> 7.2 U/mL) were found in 5% of 184 normal individuals and in 70% of 93 epithelial ovarian cancer patients with clinically evident disease. Among sera from these ovarian cancer patients, OVX1 was elevated in 68% of 76 samples with CA-125 levels more than 35 U/mL and in 76% of 17 samples with CA-125 levels less than 35 U/mL. In serum samples obtained at the time of positive second-look laparotomy, 59% of 41 patients with CA-125 levels less than 35 U/mL had elevated OVX1 antigen levels, whereas 41% of 22 patients with CA-125 levels more than 35 U/mL had elevated serum OVX1 levels. In patients with negative second-look laparotomies, false-positive results were eliminated by increasing the threshold of OVX1 to 10.5 U/mL. At this level, 32% of 41 patients with positive second-look operations had an elevated OVX1 level, despite a normal CA-125 level. When used in combination, CA-125 (> 35 U/mL) and OVX1 (> 10.5 U/mL) detected persistent disease in 56% of 63 patients with positive surveillance procedures, compared with 35% when CA-125 was used alone (P < .05).

CONCLUSION

An elevated OVX1 level can alert oncologists to the possibility that ovarian cancer has persisted, despite the return of CA-125 to a normal range.
Hydroxyurea versus misonidazole with radiation in cervical carcinoma: long-term follow-up of a Gynecologic Oncology Group trial.
Authors: Stehman F B , Bundy B N , Thomas G , Keys H M , d'Ablaing G , Fowler W C , Mortel R , Creasman W T
Published: February 2017

PURPOSE

Long-term follow-up data of a randomized trial that compared hydroxyurea and the hypoxic-cell radiosensitizer to misonidazole as adjuncts to standard radiation therapy in locally advanced carcinoma of the cervix are reported.

PATIENTS AND METHODS

Three hundred eight women were entered, and all 294 eligible patients are assessable as randomized. Eighty-one percent of patients have been monitored for 5 years or to death.

RESULTS

There was an advantage for hydroxyurea in progression-free interval and survival (P = .05 and P = .066, respectively). There was no significant difference in the distribution of sites of failure between the regimens. For the 39% of patients with stages III to IVA disease, the advantage in progression-free interval for hydroxyurea was significant (47.8% v 33.6%). More leukopenia occurred on the hydroxyurea regimen than on the misonidazole regimen.

CONCLUSION

In summary, these data provide stronger evidence than our previous analysis that hydroxyurea is superior to misonidazole as an adjunct to radiation therapy. For patients with locally advanced carcinoma of the cervix, hydroxyurea continues to be the adjunct of choice with radiation.
EPOCH chemotherapy: toxicity and efficacy in relapsed and refractory non-Hodgkin's lymphoma.

Published: February 2017

PURPOSE

Based on in vitro evidence that tumor cells are less resistant to prolonged exposure to low concentrations of the natural product class, compared with brief higher concentration exposure, we developed a chemotherapy regimen (etoposide, vincristine, doxorubicin, cyclophosphamide, and prednisone [EPOCH]) in which the natural products are administered as a continuous infusion.

PATIENTS AND METHODS

This is a phase II study of etoposide, vincristine, and doxorubicin, administered as a 96-hour continuous infusion, with intravenous (IV) bolus cyclophosphamide and oral prednisone (EPOCH) in 74 consecutive patients who relapsed from or failed to respond to most of the same drugs administered on a bolus schedule. Patients with aggressive lymphomas who achieved a good response after EPOCH were eligible to undergo bone marrow transplantation.

RESULTS

Patients with intermediate- or high-grade lymphoma comprised 76% of this series and 77% had stage IV disease. Seventy-one percent had previously received all of the drugs contained in the EPOCH regimen and 92% had received at least four of the drugs. Seventy patients were assessable for response, of whom 19 (27%) achieved a complete remission (CR) and 42 (60%) a partial remission (PR). Among 21 patients who had no response to prior chemotherapy, 15 (71%) responded, but only one achieved a CR. Patients who relapsed from an initial CR had a 100% response rate, with 76% CRs. With a median potential follow-up duration of 19 months, there was a 28% probability of being event-free at 1 year. Toxicity was primarily hematologic with neutropenia during 51% of cycles, but only a 17% incidence of febrile neutropenia. Gastrointestinal, neurologic, and cardiac toxicity were minimal.

CONCLUSION

EPOCH chemotherapy was well tolerated and highly effective in patients who were resistant to or relapsed from the same drugs administered on a bolus schedule, suggesting that continuous infusion of the natural drug component of this regimen is capable of partially reversing drug resistance and reducing toxicity. Dose-intensity (DI) was > or = that achieved in primary treatment regimens for aggressive lymphomas.
Busulfan plus cyclophosphamide followed by autologous blood stem-cell transplantation for patients with acute myeloblastic leukemia in first complete remission: a report from a single institution.
Authors: Sanz M A , de la Rubia J , Sanz G F , Martín G , Martínez J , Jarque I , Sempere A , Gomis F , Senent L , Soler M A
Published: February 2017

PURPOSE

To determine if peripheral-blood stem cells (PBSC) collected during the recovery of standard induction and consolidation chemotherapy in acute myeloblastic leukemia (AML) can be used as a safe tool for autologous transplantation, and to study aspects of the autologous blood stem-cell transplantation (ABSCT) procedure and their results in AML patients in first remission.

PATIENTS AND METHODS

Twenty-four AML patients in first remission received busulfan (BU; 16 mg/kg) and cyclophosphamide (CY; 200 mg/kg) followed by ABSCT. PBSC were collected by continuous-flow leukaphereses after induction and consolidation courses.

RESULTS

The median numbers of mononuclear cells (MNCs) and colony-forming unit granulocyte-macrophage (CFU-GM) administered were 6 x 10(8)/kg and 11 x 10(4)/kg, respectively. ABSCT induced engraftment in 22 patients and there were two graft failures. The median times to reach a polymorphonuclear (PMN) leukocyte count of 0.5 x 10(9)/L and a platelet count of 50 x 10(9)/L were 13 and 19 days, respectively. Fatal hepatic veno-occlusive disease (VOD) was observed in two cases. Other toxicities were mild and uncommon. Twelve patients relapsed between 1 and 9 months posttreatment. Actuarial disease-free survival (DFS) and actuarial risk of relapse at 30 months were 35% (95% confidence interval [CI], 25% to 45%) and 60% (95% CI, 50% to 72%), respectively.

CONCLUSION

These preliminary results show the fast hematopoietic recovery and the low infectious and hemorrhagic morbidity associated with the procedure and strongly suggest that ABSCT may be as effective as autologous bone marrow transplantation (ABMT) in AML. However, further strategies for reducing leukemic relapse must still be investigated.
