PURPOSE

To evaluate the objective tumor response rate and toxicities of patients with metastatic colorectal carcinoma treated with irinotecan hydrochloride (CPT-11).

PATIENTS AND METHODS

A total of 121 patients with advanced colorectal carcinoma--90 with prior fluorouracil (5-FU) exposure and 31 chemotherapeutically naive patients--were enrolled between May 1993 and June 1994. Patients were treated with CPT-11 at 125 mg/m2 intravenously weekly for 4 weeks followed by a 2-week rest.

RESULTS

Among 90 patients with prior 5-FU chemotherapy, 12 partial responses were observed (response rate, 13.3%; 95% confidence interval [CI], 7.1% to 22.1%). Among 31 chemotherapy-naive patients, eight had partial responses (response rate, 25.8%; 95% CI, 11.9% to 44.6%). The median response duration as measured from time of initial treatment for the two groups was 7.7 months and 7.6 months, respectively. The major adverse reactions were gastrointestinal and hematologic. The incidence of grade 3 or 4 diarrhea was 36.4%, while the overall incidence of grade 3 or 4 leukopenia was 21.5% of patients. Only four of 121 patients (3.3%) developed neutropenic fever (grade 4 neutropenia with > or = grade 2 fever). The incidence of grade 4 leukopenia was higher in patients with prior pelvic radiotherapy (chi2 test P = .04), while the incidence of grade 3 or 4 diarrhea demonstrated no association with previous pelvic irradiation.

CONCLUSION

According to the study design, CPT-11 showed promising activity in chemotherapy-naive patients with advanced colorectal carcinoma and modest activity in patients with prior 5-FU exposure. The toxicity with this schedule appears manageable with appropriate dose modification for individual patient tolerance and an intensive loperamide regimen for the management of diarrhea. Care should be taken when treating patients with prior pelvic radiotherapy because of the increased risk of neutropenia.

Published: February 2017

PURPOSE

To study the outcome achieved with three-drug chemotherapy and split-course external-beam radiotherapy as a treatment for unresectable stage II and III pancreatic carcinoma.

PATIENTS AND METHODS

Radiotherapy was given in three cycles of 2 Gy/d on days 1 to 5 and 8 to 12 (total dose, 54 Gy) concurrently with fluorouracil (FU) 1,000 mg/m2/d by continuous infusion for 4.5 days, streptozocin (STZ) 300 mg/m2 on days 1, 2, and 3 and cisplatin (P) 100 mg/m2 on day 3 of each every-28-day cycle. Subsequent treatment consisted of leucovorin (LV) 200 mg/m2 and FU 600 to 1,000 mg/m2 every 14 days.

RESULTS

The median survival time for the 35 patients was 15 months and 26% of patients were alive at 24 months. Fifteen patients (42.8%) had objective responses to therapy. Six (17%) had a complete response (CR). Three of nine patients with partial responses (PRs) achieved a radiographic CR within the next 3 months. Nine patients underwent attempts at surgical resection: five were resected (median survival time, 31 months; range, 12.8 to 44.7+), two had no residual disease found at complete resection, and three others also had a complete resection. Of four others who could not be resected, three underwent intraoperative radiotherapy and one had occult metastatic disease. Of primary tumors, 91% did not produce either back pain or local gastrointestinal complications for 2 years. The rates of severe side effects were stomatitis 15%, anemia 14%, granulocytopenia 6%, and thrombocytopenia 6%.

CONCLUSION

Palliation and survival compare favorably with other series, including many surgical series. The response findings encourage studies of both unresectable and (as neoadjuvant therapy) resectable tumors.
Cost of combined modality interventions for stage III non-small-cell lung cancer.
Authors: Evans W K , Will B P , Berthelot J M , Earle C C
Published: February 2017

PURPOSE

To evaluate the cost-effectiveness (CE) of new combined modality strategies in patients with stage III non-small-cell lung cancer (NSCLC).

METHODS

Recent studies suggest that combined modality therapy confers a survival advantage for patients with stage III NSCLC. Using the Statistics Canada (Ottawa, Canada) lung cancer costing model, we have evaluated the CE of these interventions using 1993 Canadian health care costs and the perspective of the government as payer in a universal health care system.

RESULTS

We estimate that the cost to treat a stage IIIa NSCLC patient with preoperative and postoperative chemotherapy would increase by $15,886, and a similar combined modality approach with the addition of postoperative radiotherapy would increase the cost by $22,963. Chemoradiotherapy for stage IIIb NSCLC would produce a smaller incremental cost of approximately $8,912 per case. However, these approaches are remarkably cost-effective, with cost per life-year gained (LYG) ranging from $3,348 to $14,958. Administering all chemotherapy in the outpatient department would improve CE. For sensitivity analysis, we reduced the survival gain that resulted from the three interventions by 25% and 50%, and increased the hospital per diem rates by 10%, 20%, and 30%.

CONCLUSION

Even with the most adverse assumptions, the CE estimates were all considered acceptable for new health care technologies in Canada. Overall, it appears that neoadjuvant therapy for stage IIIa NSCLC and combined modality therapy for stage IIIb NSCLC are cost-effective. Economic considerations should not be a barrier to their adoption.

Published: February 2017

PURPOSE

To confirm the efficacy of docetaxel in patients with breast cancer previously treated with one chemotherapy regimen for advanced or metastatic disease and to compare the incidence of fluid retention (FR) and skin toxicity when docetaxel is administered with and without prophylactic corticosteroids.

PATIENTS AND METHODS

Eighty-three patients, pretreated with one chemotherapy regimen for metastatic breast cancer (MBC) with bidimensionally measurable and progressive disease, were eligible for this randomized trial. Docetaxel with prophylactic oral antihistamine was administered at a dose of 50 mg/m2 as a 1-hour infusion on days 1 and 8 every 21 days and patients were randomized to receive methylprednisolone (40 mg days -1, 0, 1, 7, 8, and 9 of each cycle) (arm A) or no methylprednisolone (arm B).

RESULTS

Twenty-eight patients (34%, 95% confidence interval [CI], 23% to 45%) achieved on objective response. The median time to disease progression and median overall survival time were 5 and 13.5 months, respectively. In total, 415 cycles of docetaxel were administered (arm A: N = 219, median = six; arm B: N = 196, median = five). The most common toxicity observed was grade 3 or 4 neutropenia, which occurred in 79% of patients. Clinically significant nonhematologic side effects included skin reactions and asthenia. In an intent-to-treat analysis, patients who received methylprednisolone premedication had a delayed onset of FR (median time to onset of FR: arm A, 84 days; arm B, 62 days; P = .01) and received a higher median cumulative dose of docetaxel before the onset of FR (arm A, 333 mg/m2; arm B, 215 mg/m2; P = .001). There was no statistically significant difference in the incidence of skin toxicity between the two arms.

CONCLUSION

Docetaxel, at this dose and schedule, has definite antitumor activity in pretreated MBC patients. Moreover, this is the first randomized trial to show that corticosteroids have a favorable impact on docetaxel-induced FR.

Phase I trial of retroviral-mediated transfer of the human MDR1 gene as marrow chemoprotection in patients undergoing high-dose chemotherapy and autologous stem-cell transplantation.
Authors: Hesdorffer C , Ayello J , Ward M , Kaubisch A , Vahdat L , Balmaceda C , Garrett T , Fetell M , Reiss R , Bank A , Antman K
Published: February 2017

PURPOSE

Normal bone marrow cells have little or no expression of the MDR p-glycoprotein product and, therefore, are particularly susceptible to killing by MDR-sensitive drugs, such as vinca alkaloids, anthracyclines, podophyllins, and paclitaxel and its congeners. Here we report the results of a phase I clinical trial that tested the safety and efficacy of transfer of the human multiple drug resistance (MDR1, MDR) gene into hematopoietic stem cells and progenitors in bone marrow as a means of providing resistance of these cells to the toxic effects of cancer chemotherapy.

PATIENTS AND METHODS

Up to one third of the harvested cells of patients who were undergoing autologous bone marrow transplantation as part of a high-dose chemotherapy treatment for advanced cancer were transduced with an MDR cDNA-containing retrovirus; these transduced cells were reinfused together with unmanipulated cells after chemotherapy.

RESULTS

High-level MDR transduction of erythroid burst-forming unit (BFU-E) and colony-forming unit-granulocyte macrophage (CFU-GM) derived from transduced CD34+ cells was shown posttransduction and prereinfusion. However, only two of the five patients showed evidence of MDR transduction of their marrow at a low level at 10 weeks and 3 weeks, respectively, posttransplantation. The cytokine-stimulated transduced cells may be out-competed in repopulation by unmanipulated normal cells that are reinfused concomitantly. The MDR retroviral supernatant that was used was shown to be free of replication-competent retrovirus (RCR) before use, and all tests of patients' samples posttransplantation were negative for RCR. In addition, no adverse events with respect to marrow engraftment or other problems related to marrow transplantation were encountered.

CONCLUSION

These results indicate the feasibility and safety of bone marrow gene therapy with a potentially therapeutic gene, the MDR gene.
Preclinical and clinical studies of bone marrow uptake of fluorine-1-fluorodeoxyglucose with or without granulocyte colony-stimulating factor during chemotherapy.
Authors: Sugawara Y , Fisher S J , Zasadny K R , Kison P V , Baker L H , Wahl R L
Published: February 2017

PURPOSE

To evaluate the effect of granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) on bone marrow glucose metabolism in rodents and in patients, as assessed by 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG) uptake measured directly or by positron-emission tomography (PET) scanning.

MATERIALS AND METHODS

Groups of three rats received either daily saline, G-CSF, or GM-CSF injections for 7 days. After treatment, FDG was injected and F-18 activities in tissues measured 1 hour later. Twenty-two breast cancer patients treated with multiagent chemotherapy were sequentially studied with PET. Eleven patients received G-CSF therapy as an adjunct to chemotherapy, while 11 received chemotherapy only. The standardized uptake value-lean (SUL) of bone marrow FDG uptake was measured and compared.

RESULTS

In rats, bone marrow F-18 activity was significantly higher in both CSF groups than in the saline group (G-CSF, 0.44 +/- 0.08; GM-CSF, 0.33 +/- 0.02; saline, 0.18 +/- 0.02% injected dose [ID]/g x kg; P < .05), but the other normal tissues had comparable biodistributions to controls. In breast cancer patients, the FDG uptake of bone marrow did not change with chemotherapy alone; however, marrow uptake was increased after treatment with G-CSF. The dose of G-CSF and duration of treatment were correlated with the extent of increase in FDG uptake. The SUL of bone marrow was as follows: baseline, 1.56 +/- 0.23; after one cycle, 3.13 +/- 1.40 (P < .01); after two cycles, 2.22 +/- 0.85 (P < .05); and after three cycles, 2.14 +/- 0.79 (P < .05), respectively. Although the FDG uptake of bone marrow declined after G-CSF treatment was completed, it was higher than the baseline level for up to 4 weeks postcompletion of G-CSF and the elevated marrow FDG uptake was sustained longer than the period of blood neutrophil count elevation.

CONCLUSION

Substantial increases in bone marrow FDG uptake are rapidly induced by CSF treatments and should not be misinterpreted as diffuse bone marrow metastases.
Patient-reported symptoms after primary therapy for early prostate cancer: results of a prospective cohort study.

Published: February 2017

PURPOSE

To assess complications of therapy for early (nonmetastatic) prostate cancer.

PATIENTS AND METHODS

A prospective study of a cohort of 279 men who sought treatment advice and completed required pretreatment forms. The measures were self-reported patient symptoms and other measures of quality of life before therapy and at 3 and 12 months afterward.

RESULTS

Bowel and bladder symptoms were uncommon pretreatment. Patients frequently reported irritative bowel and bladder symptoms at 3 months after radiotherapy, although these subsided somewhat at 12 months. Substantial ("a lot") urinary incontinence and wearing of absorptive pads were reported by 11% and 35% at 12 months after surgery and varied little by age. Incontinence occurred after radiotherapy infrequently, and only in men more than 65 years old. Inadequate erections, present in one third of men pretreatment, were nearly universal at 3 months after surgery, although some improvement, primarily in men under 65 years of age, was evident at 12 months. Sexual dysfunction after radiotherapy increased less but continually through 12 months, suggesting that observed treatment-related differences would decline with further follow-up.

CONCLUSION

External-beam radiotherapy of early prostate cancer is followed by bowel and bladder irritability, by increasingly severe sexual dysfunction and, in men aged more than 65 years, occasional urinary incontinence. Greater sexual dysfunction and urinary incontinence occur in the year following radical prostatectomy. These postsurgical complication rates from patient questionnaires are greater than have been reported in other treatment series and confirm the results of two retrospective studies of patient-reported complications.
Tamoxifen and toremifene in breast cancer: comparison of safety and efficacy.
Authors: Buzdar A U , Hortobagyi G N
Published: February 2017

PURPOSE

Tamoxifen is currently the standard hormonal treatment of breast cancer, both for metastatic disease and in the adjuvant setting. A new antiestrogen, toremifene, was approved recently for use in managing metastatic breast cancer in postmenopausal women.

METHODS

Toremifene is structurally similar to tamoxifen, differing only by a single chlorine atom, and has a similar pharmacologic profile. The major difference between the two compounds is in the preclinical activity; chronic, high-dose tamoxifen is hepatocarcinogenic in the rat, whereas toremifene is not. Neither agent is hepatocarcinogenic in mice, hamsters, or humans; therefore, clinical relevance of the rat data may not be significant.

RESULTS

In a worldwide phase III trial, the two agents demonstrated comparable efficacy and safety against metastatic breast cancer. Both agents have shown a significant hypocholesterolemic effect after long-term administration.

CONCLUSION

Due to the paucity of long-term clinical data on toremifene, important unresolved questions remain, which include its effects on bone mineral density, the frequency of cardiac events, and the risk for endometrial cancer. Tamoxifen has been associated with maintenance of bone mineral density, a reduction in cardiac events, and a slightly increased risk of endometrial cancer. Toremifene is not likely to be used as second-line therapy after tamoxifen failure due to cross-resistance, and its ultimate place in therapy of advanced breast cancer remains to be determined.

Published: February 2017

PURPOSE

Interferon alfa has shown significant activity in patients with low-grade malignant non-Hodgkin's lymphoma (NHL). In 1985, we initiated a prospective randomized study in which the potential benefit of interferon alfa given as maintenance treatment was investigated after tumor load reduction was achieved with chemoradiotherapy in patients with advanced low-grade malignant non-Hodgkin's lymphoma.

PATIENTS AND METHODS

The study involved 347 patients with stage III or IV disease, 315 satisfying the eligibility criteria. All were treated with a regimen of cyclophosphamide, vincristine, and prednisone (CVP) given every 3 weeks for eight cycles. Thereafter, patients were eligible for iceberg irradiation. Finally, all patients were completely restaged, and responding and stable-disease patients were then randomized, 122 to interferon alfa-2a maintenance, 3 million U three times weekly for 1 year; and 120 to no further treatment.

RESULTS

Seventy-nine percent of the patients response to CVP, ie, 45% complete remissions (CR) and 34% partial remissions (PR). In the group of randomized patients, the response rate after CVP plus or minus radiotherapy was 90%. As compared with control patients, patients in the interferon (IFN) maintenance group had a tendency toward a prolonged time to progression (TTP) (median, 132 v 87 weeks; P = .054, adjusted for response to CVP). However, overall survival was similar in both groups. Interferon was well tolerated. The median dose of IFN actually received corresponded to 90% of the planned cumulative dose. The treatment had to be stopped because of toxicity in 16 patients (15% of the patients in whom IFN was started).

CONCLUSION

Interferon maintenance treatment in the phase of minimal residual disease of patients with advanced low-grade malignant NHL increased TTP at the borderline of statistical significance, without remarkable toxicity. However, overall survival was not influenced.

Published: February 2017

PURPOSE

A phase II study was conducted to evaluate the safety and efficacy of tirapazamine combined with cisplatin for the treatment of patients with advanced non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS

Forty-four patients with stage IIIB/IV NSCLC were treated with a combination of tirapazamine and cisplatin. Patients received tirapazamine 260 mg/m2 administered intravenously over 2 hours, followed 1 hour later by cisplatin 75 mg/m2 administered over an additional hour, repeated every 21 days. The duration of therapy was meant to be limited to four cycles for nonresponders and eight cycles for responders.

RESULTS

Ten of 44 patients (23%) showed a partial response. The estimated median survival for all patients was 37 weeks. Toxicities were treatable and included grade 3 nausea or vomiting (25%), fatigue (27.3%), and muscle cramps (4.5%). No dose reductions were necessary.

CONCLUSION

The results show that tirapazamine can safely be added to cisplatin. Both the median survival and response rate observed strongly suggest that tirapazamine with cisplatin is more active than cisplatin alone.
Secondary brain tumors in children treated for acute lymphoblastic leukemia at St Jude Children's Research Hospital.

Published: February 2017

PURPOSE

To evaluate the incidence of and potential risk factors for second malignant neoplasms of the brain following treatment for childhood acute lymphoblastic leukemia (ALL).

PATIENTS AND METHODS

The study population consisted of 1,612 consecutively enrolled protocol patients treated on sequential institutional protocols for newly diagnosed ALL at St Jude Children's Research Hospital (SJCRH) between 1967 and 1988. The median follow-up duration is 15.9 years (range, 5.5 to 29.9 y).

RESULTS

The cumulative incidence of brain tumors at 20 years is 1.39% (95% confidence interval [CI], 0.63% to 2.15%). Twenty-two brain tumors (10 high-grade gliomas, one low-grade glioma, and 11 meningiomas) were diagnosed among 21 patients after a median latency of 12.6 years (high-grade gliomas, 9.1 years; meningiomas, 19 years). Tumor type was linked to outcome, with patients who developed high-grade tumors doing poorly and those who developed low-grade tumors doing well. Risk factors for developing any secondary brain tumor included the presence of CNS leukemia at diagnosis, treatment on Total X therapy, and the use of cranial irradiation, which was dose-dependent. Age less than 6 years was associated with an increased risk of developing a high-grade glioma.

CONCLUSION

This single-institution study, with a high rate of long-term data capture, demonstrated that brain tumors are a rare, late complication of therapy for ALL. We report many more low-grade tumors than others probably because of exhaustive long-term follow-up evaluation. The importance of limiting cranial radiation is underscored by the dose-dependent tumorigenic effect of radiation therapy seen in this study.
BEACOPP, a new dose-escalated and accelerated regimen, is at least as effective as COPP/ABVD in patients with advanced-stage Hodgkin's lymphoma: interim report from a trial of the German Hodgkin's Lymphoma Study Group.

Published: February 2017

PURPOSE

The HD9 trial aims to evaluate whether moderate dose escalation and/or acceleration of standard polychemotherapy is beneficial for advanced-stage Hodgkin's disease (HD). Two variants of a novel bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) scheme (standard and escalated dose) are compared with cyclophosphamide, vincristine, procarbazine, and prednisone (COPP)/doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD).

PATIENTS AND METHODS

The randomized, three-arm trial recruited patients in stages IIB and IIIA with risk factors and stages IIIB and IV. BEACOPP in baseline dose contains all drug dosages of COPP/ABVD (except vincristine and procarbazine) rearranged in a shorter, 3-week cycle. Escalated BEACOPP uses higher doses of cyclophosphamide, doxorubicin, and etoposide with granulocyte colony-stimulating factor (G-CSF) support. After eight chemotherapy cycles, initial bulky and residual disease is irradiated. The trial is monitored and analyzed by means of a sequential strategy.

RESULTS

An interim analysis with 505 assessable patients and a median follow-up of 23 months showed a significant inferiority (according to sequential monitoring strategy) of the COPP/ABVD regimen in progression rate and freedom from treatment failure (FFTF) compared with the pooled results of both BEACOPP variants. The 24-month FFTF rate was 75% for COPP/ABVD and 84% for BEACOPP pooled (P = .034). There was 12% progressive disease with COPP/ABVD and 6% with BEACOPP pooled. Differences in survival were not significant in sequential analysis. The acute toxicity of baseline BEACOPP resembled that of COPP/ABVD; escalated BEACOPP showed increased but manageable hematologic toxicity.

CONCLUSION

Combined with local irradiation, BEACOPP in one or both variants shows superior disease control compared with COPP/ABVD, with acceptable acute toxicity. Further follow-up is required to assess the effect of dosage and the effect on survival and late toxicities.
Prolonged oral etoposide as second-line therapy for platinum-resistant and platinum-sensitive ovarian carcinoma: a Gynecologic Oncology Group study.
Authors: Rose P G , Blessing J A , Mayer A R , Homesley H D
Published: February 2017

PURPOSE

A phase II trial was conducted to determine the activity of prolonged oral etoposide in platinum-resistant and platinum-sensitive ovarian carcinoma.

PATIENTS AND METHODS

Platinum-resistant disease was defined as progression on platinum-based chemotherapy or recurrence within 6 months of completing therapy. The starting dose was 50 mg/m2/d (30 mg/m2/d for prior radiotherapy) for 21 days, every 28 days. A dose escalation to a maximum dose of 60 mg/m2/d was prescribed.

RESULTS

Of 99 patients entered, 97 were assessable for toxicity and 82 were assessable for response. Among 41 platinum-resistant patients a 26.8% response rate (7.3% complete response [CR] and 19.5% partial response [PR] rate) occurred. The median response duration was 4.3 months (range, 1.3 to 8.7), median progression-free interval (PFI) was 5.7 months (range, 0.8 to 30.8+), and median survival time was 10.8 months (range, 1.9 to 45.8). Twenty-five of 41 platinum-resistant patients had also previously received paclitaxel; of which eight (32%) responded. Among 41 platinum-sensitive patients, a 34.1% response rate (14.6% CR and 19.5% PR rate) occurred. The median response duration was 7.5 months (range, 1.9 to 15.2+), median PFI was 6.3+ months (range, 0.9 to 20.4), and median survival time was 16.5+ months (range, 0.9 to 34.8). Of 97 patients assessable for toxicity, grade 3 or 4 hematologic toxicity was common, with leukopenia occurring in 41.2% (grade 3, 29%; grade 4, 12%), neutropenia in 45.4% (grade 3, 20%; grade 4, 25%), thrombocytopenia in 9% (grade 3, 5%; grade 4, 4%), and anemia in 13.4%. Three treatment-related deaths occurred: two from neutropenic sepsis and one from thrombocytopenic bleeding after an overdose. One patient developed leukemia.

CONCLUSION

This regimen is active in platinum-resistant and platinum-sensitive ovarian carcinoma. Additionally, the regimen is active in paclitaxel-resistant ovarian carcinoma.
Second cancers following pediatric Hodgkin's disease.
Authors: Wolden S L , Lamborn K R , Cleary S F , Tate D J , Donaldson S S
Published: February 2017

PURPOSE

To define the magnitude of second cancer risk among pediatric Hodgkin's disease survivors and to determine which factors influence this risk.

PATIENTS AND METHODS

At Stanford,694 children and teenagers were monitored for 1 to 31.6 years (mean, 13.1) after treatment for Hodgkin's disease. Relative risks (RRs), actuarial risks, and absolute excess risks for second malignancies were calculated. The influences of sex, age, stage, splenectomy, treatment and relapse were assessed by multivariate analysis.

RESULTS

Fifty-six patients developed 59 secondary malignancies: 48 solid tumors, eight leukemias, and three non-Hodgkin's lymphomas. The RR of developing a second cancer was 15.4 (95% confidence interval [CI], 10.6 to 21.5) for females and 10.6 (95% CI, 6.6 to 16.0) for males. Breast cancer (n = 16) and sarcoma (n = 13) were the most common solid tumors. The actuarial risk at 20 years follow-up evaluation was 9.7% for males, 16.8% for females, and 9.2% for breast cancer. The median interval to diagnosis of a second malignancy was shortest for leukemia, 4.3 years, and longest for lung cancer, 18.4 years. Relapse of Hodgkin's disease increased the risk of second malignancy (hazards ratio [HR] = 2.6, P < .001). Hodgkin's disease stage, patient age, splenectomy, and treatment modality did not appear to alter overall risk, although chemotherapy was associated with subsequent leukemia.

CONCLUSION

Aggressive Hodgkin's disease therapy is successful, but patients have a significant risk of second malignancy. Newer treatment programs focus on obtaining a relapse-free cure of Hodgkin's disease with judicious use of radiation and alkylating agent chemotherapy. Survivors of pediatric Hodgkin's disease require lifelong evaluation and cancer screening.

Published: February 2017

PURPOSE

To evaluate the feasibility and efficacy of an intensive multimodality approach with combination chemotherapy, hyperfractionated accelerated chemoradiotherapy, and definitive surgery in prognostically unfavorable subgroups of locally advanced non-small-cell lung cancer stages IIIA and IIIB (LAD-NSCLC).

PATIENTS AND METHODS

Following staging, including mediastinoscopy, 94 patients with inoperable LAD-NSCLC were treated preoperatively with chemotherapy (three courses of split-dose cisplatin and etoposide [PE]) followed by concurrent chemoradiotherapy (one course of PE combined with 45 Gy hyperfractionated accelerated radiotherapy). After repeat mediastinoscopy, patients underwent surgery 4 weeks postradiation.

RESULTS

Of 94 consecutive patients (52 stage IIIA [> or = two lymph node levels involved] and 42 stage IIIB [no pleural effusion, no supraclavicular nodes]), 62 (66%) completed induction and underwent surgery. Complete resection (R0) was achieved in 50 (53% of all patients) and pathologic complete response (PCR) in 24 (26%). After a median follow-up of 43 months, the median survival time was 20 months for IIIA, 18 months for IIIB, and 42 months for R0 patients. Calculated survival rates at 4 years were 31%, 26%, and 46%. Two patients died of sepsis preoperatively and four died postoperatively of pleural empyema (n = 1), stump insufficiency (n = 2), and cardiac failure (n = 1). Other toxicities were acceptable-mainly hematologic during chemotherapy or chemoradiotherapy and esophagitis during chemoradiotherapy.

CONCLUSION

This intensive multimodality treatment is feasible and demonstrates high efficacy in prognostically unfavorable LAD-NSCLC subgroups with high R0 rates and improved long-term survival compared with historical controls

In a previously reported randomized Southeastern Cancer Study Group (SECSG) trial, three cycles of chemotherapy were found to be equivalent to four cycles in patients with favorable-prognosis germ-cell cancer. We have conducted a follow-up analysis of patients treated at Indiana University (Indianapolis, IN) to compare long-term survival between the two groups and to examine factors associated with survival.

PATIENTS AND METHODS

Sixty-nine patients with minimal-stage and 49 patients with moderate-stage disseminated germ-cell tumors were randomized to either three or four courses of bleomycin, etoposide, and cisplatin (BEP) administered every 3 weeks. Median follow-up time is 10.1 years (range, 7 months to 12.6 years). Ninety-two percent of patients have an actual follow-up time of > 5 years, and 97.5% of patients have an actual follow-up time of > 3 years.

RESULTS

Survival analysis shows no significant difference between the two treatment groups in terms of overall (P = .80) or disease-free (P = .93) survival. Several clinical variables were examined by univariate analysis; only serum human chorionic gonadotropin (HCG) had an impact on survival. There were two disease-related deaths in 104 patients with HCG < or = 1,000 mIU/mL and five disease-related deaths in 14 patients with HCG greater than 1,000 mIU/mL (P < .001). Ninety-eight percent (95% CI, 95.2 to 100) of patients with favorable prognosis germ-cell tumor with an initial HCG of < or = 1,000 mIU/mL are alive without evidence of disease at 5+ years.

CONCLUSION

With long-term follow-up, there is no statistically significant difference in survival between three or four cycles of BEP chemotherapy in patients with favorable prognosis germ-cell carcinoma. Serum HCG elevation of greater than 1,000 mIU/mL is a significant predictor of poor outcome in patients with otherwise good-risk disease.

Published: February 2017

PURPOSE

We report long-term paternity in men with stage I testis tumors who were managed initially by surveillance.

PATIENTS AND METHODS

One hundred five patients with clinical stage I nonseminomatous germ cell tumors of the testis were entered on a surveillance protocol and followed up for more than 10 years. Actual fertility potential was assessed by pregnancy.

RESULTS

Of the 105 patients, 41 (39%) have fathered children, which includes 36 of 78 (46%) patients while on active surveillance and five of 27 (19%) patients after treatment for relapse. Of 63 couples who attempted a pregnancy on surveillance or were presumed capable of impregnation (whether they tried or not), 41 (65%) were successful.

CONCLUSION

These results show that the majority of men with stage I testis tumor who are on surveillance after orchiectomy, have a suitable partner, and attempt impregnation achieve a successful pregnancy. Pregnancy rates appear to be less than reported in men who have a nerve-sparing retroperitoneal lymph node dissection (RPLND) because more patients on surveillance require treatment for relapse, which reduces their chances for pregnancy.

PURPOSE

In preclinical experiments, interferon alfa modulates the anticancer activity of fluorouracil (5-FU) and cisplatin (CDDP). To test this effect clinically in patients with recurrent or metastatic head and neck cancer (RMHNC), a multicenter randomized controlled trial with CDDP and 5-FU with or without interferon alfa-2b (IFNalpha) was performed.

PATIENTS AND METHODS

Eligible patients had histologically confirmed RMHNC; a good performance status; measurable disease; adequate bone marrow, hepatic, and renal function; no prior chemotherapy for recurrent or metastatic disease; only one chemotherapy regimen administered with previous local therapy; and a treatment-free interval of at least 3 months following previous local therapy. Patients were randomized and stratified according to treatment center, and prior radiotherapy and chemotherapy. The treatment regimen consisted of CDDP 100 mg/m2 on day 1 and 5-FU 1,000 mg/m2/d by continuous infusion for 96 hours (days 1 to 4), without (arm A) or with (arm B) IFNg alpha 3 x 10(6) U/d subcutaneously on days 1 to 5. Cycles were repeated every 21 days.

RESULTS

One hundred twenty-two patients were entered on each arm. The response rate (RR) was similar in both arms (arm A: complete response [CR] 10.7%, partial response [PR] 36.4%; arm B: CR 6.8%, PR 31.6%) (.70 < P < .50). There was no difference in median survival between the two arms (arm A 6.3 months v arm B 6.0 months; P = .49). Anorexia, fever, leukopenia, and thrombocytopenia grade III to IV were significantly more frequent in the IFNalpha arm.

CONCLUSION

Modulation of CDDP and 5-FU with IFNalpha as used in this study does not improve the RR or the median survival in patients with RMHNC. Patients on both study arms had a poor prognosis, which indicates the need for novel therapies.
Extravesical tumor relapse in patients with superficial bladder tumors.
Authors: Herr H W
Published: February 2017

PURPOSE

To define the incidence of extravesical urothelial tumors among patients with high-risk superficial bladder tumors.

PATIENTS AND METHODS

Three hundred seven patients with multiple recurrent papillary and in situ carcinomas of the bladder were treated with transurethral resection and intravesical bacillus Calmette Guérin (BCG) therapy and monitored for a median of 12 years (range, 10 to 18). Extravesical tumors were detected during investigation of a positive urine cytology after no tumor was found in the bladder.

RESULTS

Among 307 patients, 78 (25%) developed tumors in the upper urinary tract (UTT). Of 251 men, 61 (24%) had tumors detected in the prostatic urethra or ducts (T4p). The median times to detection of an UTT or prostatic epithelial tumor were 56 months and 11 months, respectively, and 32% of the UTT and 44% of the T4p relapses were lethal.

CONCLUSION

Patients with high-risk superficial bladder tumors who are treated successfully by a bladder-sparing strategy are at increased risk for tumor relapse that involves extravesical mucosa.

Published: February 2017

PURPOSE

A phase I, multicenter trial of the thymidylate synthase (TS) inhibitor THYMITAQ (nolatrexed dihydrochloride; Agouron Pharmaceuticals, Inc, San Diego, CA) given by 5-day continuous infusion was performed to establish the maximum-tolerated dose (MTD) and to investigate pharmacokinetics, pharmacodynamics, and antitumor effects.

METHODS

In vitro and in vivo preclinical studies demonstrated increased activity with prolonged nolatrexed exposure. In 32 patients, nolatrexed was given as a 5-day infusion at 96 to 1,040 mg/m2/d for 5 days. Pharmacokinetics were determined from high-performance liquid chromatography (HPLC) analyses of plasma and urine. In addition to studying toxicity, plasma deoxyuridine (UdR) elevations were measured as a marker of TS inhibition.

RESULTS

The MTD was 904 mg/m2/d for 5 days and the recommended phase II dose is 800 mg/m2/d for 5 days. The dose-limiting toxicity was neutropenia with clinically significant thrombocytopenia and mucositis. These antiproliferative toxicities of nolatrexed were predictable and reversible. A partial response that lasted 3 months occurred in a patient with metastatic colorectal cancer. Pharmacokinetics were nonlinear, with the median plasma clearance (CI) decreasing from 151 mL/min/m2 (range, 124 to 211) at 96 mg/m2/d for 5 days to 49 mL/min/m2 (range, 30 to 84) at 768 mg/ m2/d for 5 days. The half-life (t1/2) was 173 minutes (range, 43 to 784) and 18% (range, 9% to 35%) of the dose was excreted unchanged in the urine. Plasma UdR increased, but returned to pretreatment levels after the end of infusion. Hematologic toxicity was significantly related to nolatrexed plasma concentrations and dose.

CONCLUSION

Nolatrexed can be safely administered to patients at a dose of 800 mg/m2/d over 5 days by continuous intravenous infusion and this schedule is associated with antitumor effects. The phase II evaluation of nolatrexed is ongoing.
Interferon versus interferon plus prednisone remission maintenance therapy for multiple myeloma: a Southwest Oncology Group Study.
Authors: Salmon S E , Crowley J J , Balcerzak S P , Roach R W , Taylor S A , Rivkin S E , Samlowski W
Published: February 2017

PURPOSE

We evaluated the vincristine, doxorubicin, and dexamethasone (VAD) regimen alone or with chemosensitizers for remission induction and interferon (IFN) versus IFN plus prednisone (IFN/P) for remission maintenance in previously untreated multiple myeloma.

PATIENTS AND METHODS

Two hundred thirty-three patients were registered for remission-induction therapy with VAD or VAD plus the chemosensitizers verapamil and quinine. Patients who achieved remission were randomized to maintenance therapy with IFNalpha 3 MU in the evening three times weekly or IFN plus 50 mg of prednisone (IFN/P) on the morning after IFN until relapse.

RESULTS

Two hundred twenty-nine patients were eligible for induction. Fatal toxicities in nine patients who received VAD plus verapamil and quinine led to closure of this arm after 47 registrations. Subsequently, all patients received VAD induction. Despite the high early mortality rate on VAD plus sensitizers, overall survival by induction arm did not differ for median or 5-year survival with approximately 40% of patients surviving 5 years. Eighty-nine eligible patients who achieved remission were randomized to maintenance. Patients who received IFN/P had improved progression-free survival (median, 19 v9 months for IFN; P = .008). After 48 months, progression-free survival on IFN/P was at the thirtieth percentile, whereas it was below the tenth percentile on IFN alone. Median survival from start of maintenance was long on both arms (57 months for IFN/P v 46 months for IFN; P = .36).

CONCLUSION

IFN/Pwas more effective than IFN alone. Improved relapse-free survival may be attributable to IFN/P or to the use of prednisone for maintenance. This latter alternative is currently being studied.
Feasibility, toxicity, and biologic response of interleukin-2 after consolidation chemotherapy for acute myelogenous leukemia: a report from the Children's Cancer Group.
Authors: Sievers E L , Lange B J , Sondel P M , Krailo M D , Gan J , Liu-Mares W , Feig S A
Published: February 2017

PURPOSE

Although remission can be achieved in 80% of children with acute myelogenous leukemia (AML), many patients experience relapse. Because interleukin-2 (IL-2) can induce remission in patients with overt evidence of AML, we hypothesized that IL-2 given to patients in first remission after intensive consolidation chemotherapy might prevent relapse. This study sought to determine whether such an approach was feasible.

PATIENTS AND METHODS

Twenty-one patients in complete remission received IL-2 after completion of treatment on Children's Cancer Group (CCG) protocol 2941. Recombinant IL-2 9 x 10(6) IU/m2 daily by continuous intravenous infusion (c.i.v.) was given for 4 days. After 4 days rest, IL-2 1.6 x 10(6) IU/m2 daily c.i.v. was resumed for 10 days. We monitored patients for toxicity and measured absolute lymphocyte count, the absolute count of cells that express CD56 and CD3 antigen, and soluble IL-2 receptor alpha-chain (sIL-2R alpha) levels before the start of IL-2 and after completion of each of the two courses of IL-2.

RESULTS

Observed toxicities included fever (57%), vascular leak (48%), hypotension (38%), tachycardia (14%), rash (29%), septicemia (5%), thrombocytopenia (29%), elevated transaminase (14%), electrolyte disturbance (29%), and hyperglycemia (10%). No patient required cardiac pressors or transfer to an intensive care unit. All patients studied developed an increase in lymphocyte count, CD56 count, CD3 count, and sIL-2R alpha levels after treatment with IL-2.

CONCLUSION

This schedule of IL-2 was reasonably well tolerated by children with AML in first remission. After treatment, increased levels of sIL-2R alpha were observed. CCG is conducting a randomized prospective trial to assess the efficacy of IL-2 to prevent the relapse of AML (CCG-2961).
Unrelated donor bone marrow transplantation for children and adolescents with Philadelphia-positive acute lymphoblastic leukemia.
Authors: Marks D I , Bird J M , Cornish J M , Goulden N J , Jones C G , Knechtli C J , Pamphilon D H , Steward C G , Oakhill A
Published: February 2017

PURPOSE

Few patients with Philadelphia-positive acute lymphoblastic leukemia (Ph-positive ALL) have been cured by chemotherapy alone. Registry figures show that 38% of patients who have a matched-sibling bone marrow transplant (BMT) are disease-free 2 years after transplant, but the majority of patients lack a sibling donor. Most modern ALL protocols recommend unrelated donor (UD) BMT for patients with Ph-positive ALL in first complete remission (CR1), but the outcome of this is unknown.

PATIENTS AND METHODS

We report the results of 15 children and adolescents who had a T-cell depleted UD-BMT for Ph-positive ALL. Thirteen of 15 had been previously treated on United Kingdom ALL protocols. Nine were in CR1 and six had more advanced disease. Eleven donor recipient pairs were matched at HLA-A, HLA-B, HLA-DR, and HLA-DQ, and four were mismatched at one or two HLA loci.

RESULTS

The incidence of greater than grade I acute and chronic graft-versus-host disease (GVHD) was low (13% and 8%, respectively). Six patients have relapsed and seven patients survive at a median of 21 months post-BMT; six of seven are disease free. All seven survivors are in full-time education or work. The 2-year overall and disease-free survivals are 44% +/- 13% and 37% +/- 13% (+/- SE). None of four patients who had mismatched donors survived, but seven of 11 matched recipients survive (P < .05).

CONCLUSION

UD-BMT can produce prolonged disease-free survival in young patients with Ph-positive ALL who otherwise would have an extremely poor outlook.
