PURPOSE

For patients with Hodgkin's disease (HD) who do not achieve complete response (CR), who experience a relapse within the first year of CR, and for those who have two or more relapses, the outcome is poor. Salvage chemotherapy regimens at conventional doses produce a CR rate that ranges from 10% to 50% and a 5-year disease-free survival (DFS) between 10% and 25%. On the other hand, high-dose chemotherapy regimens given in combination with bone marrow transplantation (BMT) produce a CR rate that ranges from 40% to 80% and a 3-year DFS of approximately 40%. We report the 5-year results of a prospective study in patients with refractory HD who were treated with three courses of intensive chemotherapy without BMT.

PATIENTS AND METHODS

Thirty-nine adult patients with refractory HD were treated with three courses of intensive chemotherapy. Each cycle of chemotherapy comprised vindesine 1 mg/m2/d in continuous intravenous (IV) infusion from day 1 to day 5; Adriamycin (doxorubicin; Roger Bellon Laboratories, Neuilly, France) 40 mg/m2/d in continuous IV infusion from day 1 to day 3; carmustine 140 mg/m2/d at day 3; etoposide 200 mg/m2/d from day 3 to day 5; and methylprednisolone 120 mg/m2/d from day 1 to day 5. After the third cycle of chemotherapy, irradiation (20 Gy) was performed whenever possible and depended on previous irradiation.

RESULTS

At the end of the treatment, 31 patients (79%) were in CR. Among these patients, 10 relapsed after a median time of 3 months. The overall 5-year survival rate was 46%. The freedom from progression (FFP) and the freedom from treatment failure (FFTF) rates were 48% and 43%, respectively. The main toxicities were hematologic (neutropenia and thrombocytopenia) and digestive. Four patients died due to treatment-related complications (two from septic shocks, one from respiratory insufficiency, and one from posttransfusional AIDS).

CONCLUSION

The results of this study seem to be comparable to those results obtained with high-dose chemotherapies with autologous BMT.

Published: February 2017

PURPOSE

Acute and chronic graft-versus-host disease (GVHD) continues to be the major causes of morbidity and mortality after allogeneic bone marrow transplantation (BMT). In this study, we have evaluated the clinical effects of selective in vitro T-cell depletion of donor allogeneic bone marrow by using a single monoclonal antibody ([MoAb] anti-T12, CD6) and rabbit complement. This antibody recognizes mature T cells, but not other cellular elements such as natural-killer (NK) cells, B cells, and myeloid precursors.

PATIENTS AND METHODS

From August 1983 to April 1991, 112 consecutive adult patients with hematologic malignancies underwent BMT with bone marrow from HLA-identical sibling donors. Marrow was harvested and depleted of mature T lymphocytes ex vivo by the use of three rounds of incubation with an anti-T12 antibody and rabbit complement. The preparative regimen consisted of cyclophosphamide and fractionated total body irradiation (TBI) in 108 patients. No patients received prophylactic immune suppression post-BMT. Purgation by anti-T12 was used as the only method for the prevention of GVHD.

RESULTS

Twenty patients (18%) developed acute GVHD (grade 2 to 4); only eight patients developed chronic GVHD. The incidence of GVHD did not increase significantly with age. Only three of 112 patients (2.7%) exhibited acute graft failure. One patient developed late graft failure that was associated with cytomegalovirus (CMV) infection. Within the subset of 50 patients who had not previously undergone unsuccessful conventional therapy (acute leukemia in first remission or chronic myelogenous leukemia [CML] in stable phase), we estimated by the Kaplan-Meier method that the probability of disease-free survival was 50% at 3 years post-BMT, with a median follow-up of 44 months. The treatment-related mortality rate in this group was only 14% and was independent of patient age.

CONCLUSIONS

We conclude that selective in vitro T-cell depletion with an anti-T12 monoclonal antibody effectively reduces the incidence of both acute and chronic GVHD after allogeneic BMT without compromising engraftment. Moreover, depletion of CD6-positive cells from donor marrow obviates the need to administer immune suppressive medications to the majority of patients. This approach reduces the morbidity and mortality of allogeneic BMT and permits the BMT of older patients.
Neoadjuvant chemotherapy and radiotherapy followed by surgery in stage IIIA non-small-cell carcinoma of the lung: report of a Cancer and Leukemia Group B phase II study.

Published: February 2017

PURPOSE

This phase II trial was designed to evaluate the feasibility, toxicity, response rates, and survival for neoadjuvant chemotherapy and radiotherapy (RT) followed by surgical resection in newly diagnosed patients with surgically staged IIIA non-small-cell lung carcinoma (NSCLC).

PATIENTS AND METHODS

Previously untreated patients with NSCLC underwent bronchoscopy, chest and abdominal computed tomography (CT), bone scan, and surgical staging of the mediastinum. Neoadjuvant treatment consisted of concurrent chemotherapy and RT. Patients then underwent surgical resection, which was followed in turn by additional chemotherapy and RT. Chemotherapy included cisplatin 100 mg/m2 on days 1 and 29, vinblastine 3 mg/m2 on days 1 and 3 and 29 and 31, and fluorouracil (5-FU) 30 mg/kg/d by infusion on days 1 to 3 and 29 to 31 (FVP). RT began on day 1 and included 3,000 cGy in 15 fractions. Surgery took place on day 55, and one more cycle of chemotherapy and an additional 3,000 cGy of RT began on day 85.

RESULTS

Forty-one eligible patients (median follow-up, 53 months) were studied. N2 disease was present in 80%, whereas 20% had T3N0 or T3N1 lesions. Response to neoadjuvant chemotherapy and RT included no complete responses (CR), 21 (51%) partial responses (PR) or regressions, 19 (46%) stable disease (SD), and one (2%) progressive disease (PD). Thirty-one patients underwent surgery, and 25 were resected. In four of the 25 resection specimens, no viable tumor was present, whereas in three of the six unresectable patients, extensive biopsy results demonstrated only necrotic tumor. The maximum response achieved using all protocol treatment was 27 (66%) CRs, seven (17%) PRs or regression, six (15%) SDs, and one (2%) PD. Toxicity was substantial and primarily hematologic. There were six (15%) treatment-related deaths, which included three perioperative deaths and three chemotherapy-related toxicity deaths. The Kaplan-Meier curve indicated a 1-year survival of 58% and a median survival of 15.5 months. Nine patients (22%) remain disease-free.

CONCLUSIONS

There was a reasonably high rate of PR associated with concurrent neoadjuvant chemotherapy and RT, and a high percentage of patients who ultimately were rendered completely disease-free. However, treatment-related morbidity and mortality was common. Median survival seemed to be only modestly improved beyond that achieved with less intensive means of treatment. However, a group has emerged of patients who enjoy prolonged disease-free survival and possible cure.
Diffuse small cleaved-cell lymphoma: a heterogeneous disease with distinct immunobiologic subsets.
Authors: Leith C P , Spier C M , Grogan T M , Gonzales G , Rangel C S , Rybski J A , Matzner M , Miller T P
Published: February 2017

PURPOSE AND METHODS

Diffuse small cleaved-cell lymphoma (DSCL) is a relatively uncommon non-hodgkin's lymphoma (NHL) in the United States and has not been the subject of recent in-depth study of factors predictive of outcome. It is unique among the NHL of intermediate grade because there is no evidence of a curable subset of patients. To investigate whether any laboratory data might predict outcome, we studied 33 cases collected during a 12-year period and correlated morphology, immunohistochemistry, and serum lactate dehydrogenase (LDH) with clinical data and outcome.

RESULTS

We found that proliferative rate (Ki-67), cell lineage (T v B cell), and serum LDH were associated with significant differences in survival. A Ki-67 value greater than or equal to 20% was associated with a median survival of 20 months compared with 80 months for lower values (P = .0002); patients with tumors of T-cell lineage had a median survival of 20 months compared with 40 months for those with B-cell neoplasms (P = .0143); and a serum LDH greater than 225 IU/L was associated with a median survival of 8 months compared with 40 months for lower LDH levels (P = .0004). Blastoid morphology was also linked to a trend toward poor outcome (P = .08). Neither a history of low-grade lymphoma nor the presence of residual immunologically detectable follicles influenced outcome (P = .93 and .97, respectively).

CONCLUSION

We conclude that high Ki-67, high LDH, and T-cell lineage each identify DSCL patients with poor outcome.

Published: February 2017

PURPOSE

The prognosis and factors that influence prognosis following salvage mastectomy in patients with recurrence in the treated breast after conservative surgery (CS) and radiation therapy (RT) were investigated.

MATERIALS AND METHODS

A total of 1,593 patients with stage I or II invasive breast cancer were treated following gross total excision of the tumor at the Joint Center for Radiation Therapy (JCRT) between 1968 and 1985. One hundred sixty-six of the 1,593 (10%) had subsequent recurrence in the breast. Of these, 123 had salvage mastectomy and constitute the study population. The recurrent tumor was predominantly invasive in 99 patients, noninvasive in 14, and focally invasive in 10. Following mastectomy, chemotherapy or hormonal therapy was administered to 29 patients. The median follow-up time was 39 months after salvage mastectomy.

RESULTS

The 5-year actuarial rate of further local or distant relapse for the entire group was 41%. None of the 24 patients with focally invasive or noninvasive tumors had a subsequent relapse. In comparison, the 5-year actuarial rate of further relapse in the 99 patients with a predominantly invasive recurrence was 52% (P = .001). The method of detection of the recurrence, the age of the patient at initial diagnosis, the disease-free interval, and the location of the recurrence in the breast were not found to have a statistically significant association with the risk of further relapse.

CONCLUSION

We conclude that the histology of the recurrent tumor is an important prognostic factor for the risk of further relapse. Patients with purely noninvasive or focally invasive tumors have an excellent prognosis following salvage mastectomy. In contrast, patients with predominantly invasive tumors are at substantial risk for further relapse.
A pilot study of pi-class glutathione S-transferase expression in breast cancer: correlation with estrogen receptor expression and prognosis in node-negative breast cancer.
Authors: Gilbert L , Elwood L J , Merino M , Masood S , Barnes R , Steinberg S M , Lazarous D F , Pierce L , d'Angelo T , Moscow J A
Published: February 2017

PURPOSE AND METHODS

Previous studies have indicated that RNA levels for pi-class glutathione S-transferase (GST pi), a phase II, drug-metabolizing enzyme, were inversely related to estrogen receptor (ER) and progesterone receptor (PR) levels in human breast tumors. Because GST pi also is expressed in normal breast epithelium, an immunohistochemical assay that uses affinity-purified polyclonal antibodies to GST pi was developed to examine the possible relationship between GST pi expression in breast cancer cells and hormone receptor expression, as well as prognosis, in patients with primary breast cancer.

RESULTS

A strong inverse correlation between GST pi expression and ER (two-sided P [P2] = .002) and PR status (P2 = .023) was found in our study of 189 patients with primary breast cancer. GST pi expression was not related to tumor size, nodal metastasis, nuclear grade, histology, or age of the patient. In node-negative breast cancer (n = 72), increased GST pi expression was associated with decreased disease-free survival (DFS) and overall survival (OS). When GST pi expression was divided into categories of negative (no GST pi-positive tumor cells), intermediate (1% to 70% GST pi-positive tumor cells), and high (> 70% GST pi-positive tumor cells), the relative risk of tumor recurrence in patients with node-negative breast cancer was increased 3.39-fold for each successive category of expression (P2 = .0045; 95% confidence interval, 1.46 to 7.87) and the relative risk of death was increased 4.49-fold for each successive category (P2 = .0003; 95% confidence interval, 2.02 to 10.42). The actuarial 5-year OS was 100%, 79%, and 51%, and the DFS was 94%, 77%, and 44%, for the negative, intermediate, and high tumor groups, respectively. Among the factors studied in multivariate analysis (ER status, PR status, nuclear grade, and tumor size), GST pi expression was the factor that most accurately predicted shorter DFS and OS in node-negative patients.

CONCLUSION

GST pi expression is inversely related to hormone receptor status in breast cancer. This pilot study also suggests that increased GST pi expression may be an important predictor of early recurrence and death in node-negative breast cancer patients that merits additional investigation.
Multicenter phase II trial of mitoxantrone in patients with advanced nasopharyngeal carcinoma in Southeast Asia: an Asian-Oceanian Clinical Oncology Association Group study.

Published: February 2017

PURPOSE

Patients with advanced nasopharyngeal carcinoma (NPC) have a high incidence of recurrence and often develop distant metastases despite local control. This prospective multicenter phase II trial was conducted to evaluate the safety and efficacy of Novantrone (mitoxantrone; Lederle Laboratories, Wayne, NJ) in the therapy of patients with advanced NPC.

PATIENTS AND METHODS

One hundred eight patients with advanced NPC, namely, those with recurrent or persistent disease following primary radiotherapy, or newly diagnosed metastatic disease, were treated with mitoxantrone. Mitoxantrone was administered intravenously at an initial dose of 12 mg/m2 and repeated every 3 weeks, with dose escalation to a maximum of 14 mg/m2. The distribution of histologic subtypes was representative of NPC, with the majority being (61%) undifferentiated (or anaplastic) carcinoma.

RESULTS

The overall response rate (complete response [CR] and partial response [PR]) was 25% (95% confidence interval, 17% to 33%). The median response duration, time to treatment failure, and survival duration were 140, 82, and 394 days, respectively. Histology (poorly differentiated squamous cell) was found to be the only important factor in predicting response (P = .04) based on a multivariate analysis of nine pretreatment characteristics. The major dose-limiting toxicity was leukopenia. The incidences of nausea/vomiting, alopecia, and stomatitis/mucositis were 34%, 6%, and 3%, respectively. None were severe. Two patients had asymptomatic, moderate Alexander-grade cardiotoxicity.

CONCLUSION

This study represents a large, controlled multicenter trial of single-agent mitoxantrone in the treatment of advanced NPC. Mitoxantrone was well tolerated and produced an overall response rate comparable to that of other single-agent therapies used in the treatment of advanced head and neck cancer. Combination trials with mitoxantrone for advanced disease should be considered.
Randomized comparison of diaziquone and carmustine in the treatment of adults with anaplastic glioma.
Authors: Schold S C , Herndon J E , Burger P C , Halperin E C , Vick N A , Cairncross J G , Macdonald D R , Dropcho E J , Morawetz R , Bigner D D
Published: February 2017

PURPOSE

We conducted a phase III trial comparing intravenous (IV) diaziquone (AZQ) and carmustine (BCNU) as single agents in patients with cerebral anaplastic gliomas who had received surgery and radiotherapy. Its purpose was to compare the efficacy of AZQ with that of BCNU, the standard agent for brain tumor chemotherapy.

PATIENTS AND METHODS

Randomization between the two regimens occurred 8 weeks after completion of radiotherapy. A total of 251 patients were randomized to receive either AZQ or BCNU, and there were no significant differences between the two treatment arms in any of the known prognostic variables, including age, histologic grade, and Karnofsky performance status (KPS).

RESULTS

There was no significant difference in either time to tumor progression or survival between the two treatment arms. Age and histology were strong predictors of outcome, whereas KPS had relatively less effect. Three groups of patients with distinctly different outcomes could be identified: (1) older age (45+) and glioblastoma/gliosarcoma (GBM/GS) patients had a median survival of 37 weeks after randomization; (2) patients with either older age or GBM/GS had a median survival of 61 weeks; and (3) younger age (< 45) and non-GBM/GS (usually anaplastic astrocytoma) patients had a median survival of 147 weeks. Toxicity was primarily hematologic, although acute gastrointestinal toxicity and chronic pulmonary toxicity were more common with BCNU. Patients randomized to AZQ who had significant hematologic toxicity that required dose reduction after the first treatment cycle had significantly longer time to tumor progression and survival than those who did not require dose reduction (P = .011 and .016, respectively).

CONCLUSION

There was no significant difference in efficacy between AZQ and BCNU in patients with anaplastic gliomas as tested in this study, although AZQ was somewhat better tolerated.
Expression of epidermal growth factor receptor and survival in upper aerodigestive tract cancer.
Authors: Dassonville O , Formento J L , Francoual M , Ramaioli A , Santini J , Schneider M , Demard F , Milano G
Published: February 2017

PURPOSE

To determine the expression of epidermal growth factor receptor (EGFR) in head and neck squamous cell carcinoma and to evaluate its prognostic value.

MATERIALS AND METHODS

EGFR was determined in tumor biopsies obtained from 109 consecutive patients with head and neck cancer (100 men, nine women). Control biopsies were obtained from 94 patients in a symetric nontumoral area of the same anatomic site. EGFR was measured by a binding assay using human recombinant iodine 125-EGF.

RESULTS

The presence of detectable EGFR levels was found in all explored tumors with highly marked differences between patients (median, 71 fmol/mg protein; range, 2 to 2,302). In 93 of 94 cases, EGFR levels were higher in tumor samples as compared with healthy control zones. There was no significant difference in EGFR expression according to the various anatomic sites explored or tumoral differentiation status. There was a significant difference of distribution for EGFR levels between stages I and II tumors and stages III and IV tumors. The tumor EGFR levels were not linked to the response to first-line chemotherapy by cisplatin (CDDP) and fluorouracil (5FU). Survival was assessable for 103 patients for overall survival and for 81 patients for recurrence. EGFR overexpression was associated with shorter relapse-free (P = .0125) and overall survival (P = .028) rates. By multivariate analysis, the only significant variable was EGFR for relapse-free survival and tumor staging for overall survival. The association of EGFR to tumor staging markedly improves the significance for overall survival predictability (P = .002).

CONCLUSION

EGFR determination deserves particular attention in head and neck cancer, since it independently carries a strong prognostic value.
Comparison of the prognostic significance between the number of metastatic lymph nodes and nodal stage based on their location in patients with gastric cancer.
Authors: Ichikura T , Tomimatsu S , Okusa Y , Uefuji K , Tamakuma S
Published: February 2017

PURPOSE

To determine which is the better prognostic determinant in gastric cancer: number of positive metastatic lymph nodes or current nodal stage.

PATIENTS AND METHODS

Seven hundred seventy-seven patients who underwent potentially curative resections for gastric cancer were divided into three groups according to the depth of invasion. The influence of the number of positive nodes on their survival rate was analyzed. A multivariate analysis by the Cox proportional hazards model was used to determine independent prognostic factors.

RESULTS

A decreased survival rate was associated with an increased number of positive nodes in all of the subjects and in each of the three groups. Patients with one to three positive nodes had as good a prognosis as those without nodal involvement when each of the three groups was analyzed separately. Using a multivariate analysis in the patients with four or more positive nodes, we found that the number of positive nodes was the most important prognostic determinant (P < .0001), followed by the depth of invasion (P < .02), and that the nodal stage was not significantly prognostic. Further multivariate analysis in the patients with one to three positive nodes showed that nodal stage and number of positive nodes were not significantly prognostic.

CONCLUSION

The number of metastatic nodes should be adopted for classification of nodal stage in gastric cancer.

Authors: Dimery I W , Peters L J , Goepfert H , Morrison W H , Byers R M , Guillory C , McCarthy K , Weber R S , Hong W K
Published: February 2017

PURPOSE

This prospective trial was conducted with the goal of achieving an improvement in both overall and progression-free survival in previously untreated patients with stage IV nasopharyngeal carcinoma who received an induction chemotherapy regimen of fluorouracil (5-FU) and cisplatin followed by radiotherapy.

PATIENTS AND METHODS

From January 1985 to January 1990, 47 patients with T1-4N2-3M0 squamous cell carcinoma of the nasopharynx were treated at The University of Texas M.D. Anderson Cancer Center with two to three cycles of 5-FU (1,000 mg/m2 continuous infusion per day x 5 days) plus cisplatin (100 mg/m2 continuous infusion on day 1 only) followed by radiotherapy using the conventional time/dose schedule.

RESULTS

The response rate to chemotherapy was 93.2% (20.5% complete response [CR]; 72.7% partial response [PR]), and the overall CR rate after radiotherapy was 86%. With a median follow-up period of 53 months, the 2-, 4-, and 6-year survival rates were 80%, 71.6%, and 67.4%; the overall treatment failure rate was 27%. Treatment was well tolerated and without significant acute or chronic toxic effects.

CONCLUSION

The results of this prospective study demonstrate that 5-FU plus cisplatin followed by radiotherapy can induce a durable remission in a high proportion of patients with poor-prognosis stage IV nasopharyngeal carcinoma.
Richter's syndrome: a report on 39 patients.
Authors: Robertson L E , Pugh W , O'Brien S , Kantarjian H , Hirsch-Ginsberg C , Cork A , McLaughlin P , Cabanillas F , Keating M J
Published: February 2017

PURPOSE

The incidence, clinical features, laboratory findings, and treatment results of 39 patients with Richter's syndrome (RS) are reported.

PATIENTS AND METHODS

Thirty-nine of 1,374 patients with chronic lymphocytic leukemia (CLL) developed RS.

RESULTS

Features associated with RS included systemic symptoms (59%), progressive lymphadenopathy (64%), extranodal involvement (41%), elevation of lactate dehydrogenase (LDH; 82%), and a monoclonal gammopathy (44%). Analysis of the CLL karyotype showed no specific chromosomal abnormality that conferred increased risk; however, multiple abnormalities were common. Patients at all Rai stages and in complete response (CR) were at risk, including three CR patients with no residual disease at the level of detection by dual-parameter flow cytometry or restriction analysis for immunoglobulin (Ig) gene rearrangements. The incidence was not higher in patients who had received prior fludarabine or chlorodeoxyadenosine. The median survival duration was only 5 months, despite multiagent therapy. Patients who responded had prolonged survival durations (P < .001). Three of eight patients who survived more than 1 year had a de novo presentation of both CLL and large-cell lymphoma (LCL). Comparison of surface light-chain analysis from both low- and high-grade components demonstrated isotypic light-chain expression in 12 of 15 patients. Ig heavy- and light-chain gene rearrangement analysis showed identical rearrangement patterns in five of five patients.

CONCLUSION

The clinical, laboratory, and survival characteristics of our RS patients were similar to those reported in earlier studies. Ig gene rearrangement and light-chain isotype analysis support a common origin for CLL and LCL. Despite progress in the treatment of CLL, the development of LCL remains a serious complication and continued surveillance in all CLL patients is warranted.
Low-dose gallium nitrate for prevention of osteolysis in myeloma: results of a pilot randomized study.
Authors: Warrell R P , Lovett D , Dilmanian F A , Schneider R , Heelan R T
Published: February 2017

PURPOSE

Since osteolysis is a major cause of morbidity in myeloma, we conducted a pilot study to evaluate whether the addition of gallium nitrate to standard antimyeloma treatment could preserve or increase bone mass in patients with osteolytic disease.

METHODS

Patients stabilized on cytotoxic therapy were randomized to treatment with gallium nitrate for 6 months, or to observation only for the first 6 months followed by gallium nitrate treatment during the subsequent 6 months. Gallium nitrate was administered in monthly cycles by daily subcutaneous injections (30 mg/m2/d) for 2 weeks, followed by 2 weeks with no therapy, supplemented by an intravenous infusion (100 mg/m2/d) for 5 days every other month.

RESULTS

Paired 6-month comparisons were available for seven observation periods and 13 gallium nitrate treatment periods. Total-body calcium assessed by delayed-gamma neutron activation (DGNA) decreased in four of seven patients during observation, but increased in nine of 13 patients during gallium nitrate treatment; the mean difference in total-body calcium (TBCa) between the two groups at 6 months was 3%. Median regional bone density assessed by dual-photon absorptiometry (DPA) declined by 1.4% in patients under observation (range, +6.7% to -18.3%), but was unchanged during gallium nitrate treatment (median change, 0%; range, -10.5% to +14.4%). The group mean vertebral fracture index assessed by lateral spine x-rays decreased by 27% during observation compared with 2% during gallium nitrate treatment. Mean body height decreased by 0.57 inches in the observation group and .06 inches in the gallium nitrate group. Patient self-assessment of bone pain showed that seven of 12 gallium nitrate-treated patients rated themselves as experiencing major reductions in bone pain, compared with zero of seven patients who were observed. One episode of hypercalcemia occurred in a patient under observation.

CONCLUSION

Adjuvant treatment with low-dose gallium nitrate attenuates the rate of bone loss in myeloma and may be useful for ameliorating the consequences of skeletal morbidity in patients with cancer-related osteolysis.
Secondary acute myeloid leukemia in children with acute lymphoblastic leukemia treated with etoposide.
Authors: Winick N J , McKenna R W , Shuster J J , Schneider N R , Borowitz M J , Bowman W P , Jacaruso D , Kamen B A , Buchanan G R
Published: February 2017

PURPOSE

To describe the occurrence of secondary acute myeloid leukemia (AML) in children with acute lymphoblastic leukemia (ALL) treated with etoposide (VP-16).

PATIENTS AND METHODS

Two hundred five consecutive children with early B-lineage ALL were treated according to the Dallas/Fort Worth (DFW) protocol between January 1986 and July 1, 1991. Therapy included a four-drug induction followed by consolidation and continuation phases of nightly oral mercaptopurine (6-MP) and repetitive courses of divided-dose oral methotrexate (dMTX) and asparaginase (L-asp). Three doses of VP-16 and cytarabine (Ara-C) were given during consolidation and later, during continuation, two doses were given 3 to 4 days apart, every 9 weeks. Intrathecal (IT) chemotherapy was given throughout the treatment period.

RESULTS

Two hundred three of the 205 patients entered remission. Only eight of these 203 children have had a bone marrow relapse (ALL). However, 10 other children have developed secondary AML 23 to 68 months following the diagnosis of ALL. Overall event-free survival (EFS) at 4 years is 79.3% +/- 5.1%, with a risk of secondary AML at 4 years of 5.9% +/- 3.2%.

CONCLUSION

This experience provides strong evidence for a link between epipodophyllotoxin therapy and secondary AML since none of these children received alkylating agent therapy or irradiation. This serious complication raises concern as to the appropriate use of epipodophyllotoxins in the treatment of childhood ALL.
Clinical features and prognosis of follicular large-cell lymphoma: a report from the Nebraska Lymphoma Study Group.
Authors: Anderson J R , Vose J M , Bierman P J , Weisenberger D D , Sanger W G , Pierson J , Bast M , Armitage J O
Published: February 2017

PURPOSE

Our purpose was to describe the treatment outcome of patients with follicular large-cell lymphoma (FLCL) and to identify prognostic factors that affect the treatment outcome.

PATIENTS AND METHODS

Between 1980 and 1991, 107 newly diagnosed, previously untreated patients with FLCL were prospectively treated using treatment plans of the Nebraska Lymphoma Study Group (NLSG). Most stage I/II patients received two to three cycles of one of four closely related six-drug combination chemotherapy regimens (cyclophosphamide, doxorubicin or mitoxantrone, and procarbazine, plus bleomycin, vincristine, and prednisone or dexamethasone [CAP/BOP I-IV]) plus involved-field radiotherapy; 10 patients received involved-field irradiation only. Stage III/IV patients received six to eight cycles of CAP/BOP.

RESULTS

Forty-four percent of patients had stage I/II disease. Stage I/II patients were older and more often female than stage III/IV patients. Cytogenetic studies were available on 35 patients: seven were normal; the most common abnormality was a translocation involving 14q32. Abnormalities of 1p or 1q were also common, often secondary to a 14q32 abnormality. The median follow-up of surviving patients is 2 years. The complete response rates observed were stage I/II, 88%; stage III/IV, 49%. Complete response rates were affected by both age and tumor bulk. Failure-free survival (FFS; time to first occurrence of progression, relapse after response, or death from any cause) at 3 years was estimated to be 61% for stage I/II patients and 34% for stage III/IV patients. Survival at 3 years was estimated to be 76% and 61%, respectively. FFS of stage III/IV patients was poorer for stage IV patients and those with composite lymphomas. Significantly poorer survival was only seen in patients older than 70 years of age.

CONCLUSION

A proportion of stage I/II FLCL patients may obtain long-term disease control with combination chemotherapy plus radiotherapy. Results for patients with stage III/IV FLCL are similar to those seen for other follicular lymphomas.
Treatment of CNS relapse in children with acute lymphoblastic leukemia: A Pediatric Oncology Group study.
Authors: Winick N J , Smith S D , Shuster J , Lauer S , Wharam M D , Land V , Buchanan G , Rivera G
Published: February 2017

PURPOSE

To assess the efficacy and toxicity of chemotherapy and cranial radiation for the treatment of children with acute lymphoblastic leukemia (ALL) following first isolated CNS relapse.

PATIENTS AND METHODS

One hundred twenty children were treated on Pediatric Oncology Group (POG) protocol 8304. All children had received prophylactic CNS therapy during their initial treatment. The treatment protocol included a four-drug reinduction and six weekly doses of triple intrathecal therapy (TIT). Cranial radiation, 24 Gy, was followed by monthly TIT. Systemic consolidation and maintenance therapy included 6-week cycles of mercaptopurine/methotrexate (6MP/MTX) and vincristine/cyclophosphamide (VCR/CTX), with randomization to intervening pulses of prednisone/doxorubicin (PDN/DOX) or teniposide (VM26)/cytarabine (Ara-C) for a total of 88 weeks.

RESULTS

All 120 patients achieved a second complete remission. There have been 61 protocol failures. Thirty-five patients had a bone marrow relapse, four with simultaneous CNS involvement and one with concurrent testicular leukemia. Thirteen patients had a second isolated CNS relapse, 10 a testicular relapse, and two relapsed in other sites. One patient died in remission. Overall event-free survival (EFS) at 4 years was 46% +/- 7%. The toxicity associated with this protocol was minimal except for leukoencephalopathy, which occurred in 20 (17%) patients. The treatment comparison between VM26/Ara-C or PDN/DOX pulses showed a trend toward superior EFS (P = .12) in favor of VM-26/Ara-C.

CONCLUSION

To date, this represents the largest series of patients with ALL treated uniformly for an isolated CNS relapse. Since marrow relapse remains the primary site of failure, future protocols must intensify systemic therapy.

PURPOSE

This study was performed to assess the short- and long-term toxicities and the impact on relapse pattern and survival of postoperative intraperitoneal (IP) cisplatin and fluorouracil (FU) plus systemic intravenous (IV) FU as adjuvant therapy for gastric cancer patients who are at high risk for recurrence after potentially curative resection (T2N1-2M0 or T3-4N(any)M0).

PATIENTS AND METHODS

Starting 14 to 28 days after potentially curative resection of primary gastric cancers, 35 patients were given IP cisplatin 25 mg/m2 and FU 750 mg daily for 4 days; FU 750 mg/m2 was concurrently given as a continuous 24-hour i.v. infusion. Five cycles of therapy delivered at 1-month intervals were used.

RESULTS

After a median follow-up of 24 months, 51% of patients remain alive and free of disease. Sixteen patients have recurred; 13 of 16 had an intraabdominal component, whereas three had extraabdominal failure only. Two major treatment-related toxicities were noted: neutropenia and a late toxicity of peritoneal fibrosis (sclerosing encapsulating peritonitis [SEP]). There was one postoperative death. Eleven patients underwent second laparotomy: five patients had SEP, two patients had bowel obstruction from adhesions unrelated to SEP, and four patients had recurrent cancer. Potential causes of SEP included an alkaline pH of infused FU and cisplatin that possibly led to activation of cisplatin before infusion.

CONCLUSION

IP cisplatin and FU and concurrent systemic FU is a tolerable adjuvant therapy in the postoperative setting for patients with resected gastric cancer. The recommended dosage schedule with this technique is cisplatin 25 mg/m2 and FU 750 mg total dose IP with FU 500 mg/m2 as a continuous 24-hour infusion daily for days 1 to 4. SEP as a late toxicity, which was observed in 15% of patients, is treatable by surgical lysis of adhesions.

PURPOSE

This study describes the physiologic and biologic effects resulting from the adoptive transfer of ex vivo anti-CD3-stimulated T-killer cells (T-AK) to patients with advanced cancer in combination with interleukin-2 (IL-2).

METHODS

Autologous peripheral-blood mononuclear cells were obtained by leukapheresis and stimulated ex vivo with anti-CD3. The stimulated cells were reinfused at one of three dose levels on the next day (5 x 10(9), 7.5 x 10(9), and 1 x 10(10)). Cell administration was followed by IL-2 given by bolus and continuous infusion (1.5 x 10(6) U/m2 and 3.0 x 10(6) U/m2, respectively) for 7 days, or continuous infusion alone (3.0 x 10(6) U/m2) for 14 days.

RESULTS

Pronounced leukocytosis and atypical lymphocytosis were observed with individual values as high as 80,000 and 50,000 cells/microL, respectively. The other major clinical sequelae included a marked lactic acidosis with bicarbonate levels as low as 4.0 mmol/L in some patients, and prolongation of the prothrombin time (PT) and partial thromboplastin time (PTT) due to decreases in clotting factors VII, IX, and X. Antithrombin III levels were also reduced. Hypotension associated with increased serum nitrate and neopterin levels was observed. These toxicities were accompanied by increases in hepatocellular enzymes and creatinine previously described with IL-2. These events occurred at a time when the number of circulating T-AK cells reached their peak. The amount of bolus IL-2 correlated with increases in WBC count (P = .0311), atypical lymphocytes (P = .0241), PT (P = .0006), and PTT (P = .0122).

CONCLUSION

Substantial in vivo expansion of activated T lymphocytes was induced by a protocol combining ex vivo activation of peripheral-blood cells with anti-CD3 antibody followed by adoptive transfer and IL-2 administration. The synchronous expansion of these T cells superimposed on diminished liver and kidney function from IL-2 can cause profound but reversible metabolic changes.

PURPOSE

To determine better the activity of high-dose interleukin-2 (IL-2) either alone or in combination with interferon alfa-2b (IFN; Schering-Plough, Kenilworth, NJ) in patients with metastatic renal cell carcinoma, the IL-2 Working Group initiated a randomized phase II trial.

PATIENTS AND METHODS

Patients were randomly assigned to receive treatment with either IL-2 (Chiron Corp, Emeryville, CA) 1.33 mg/m2 (approximately 600,000 IU/kg) alone or IL-2 0.8 mg/m2 and IFN 3 x 10(6) U/m2 administered by bolus intravenous injection every 8 hours, days 1 to 5 and 15 to 19 (maximum, 28 doses). All patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 and normal organ function. After 28 patients were entered onto each arm, the IL-2/IFN arm was closed because of a failure to meet predetermined efficacy criteria. An additional 43 patients (total, 71) were assigned to receive IL-2 alone.

RESULTS

Toxicities were similar for both study arms. Hypotension requiring pressors was the most frequent dose-limiting toxicity. Only 11 of 99 patients experienced severe toxicity; there were no irreversible side effects or treatment-related deaths. Responses were seen in three of 28 patients (11%) on IL-2/IFN (three partial responses [PRs] lasting 14, 7, and 7 months) and 12 of 71 patients (17%) on IL-2 alone (four complete responses [CRs] and eight PRs). Six of the partial responders on IL-2 and two on IL-2/IFN experienced greater than 90% reduction in tumor mass. Ten of the 12 responders to IL-2 have ongoing responses of 12+ to 26+ months in duration.

CONCLUSION

We conclude that both IL-2 and IL-2/IFN therapy have activity in metastatic renal cell carcinoma. In particular, therapy with high-dose IL-2 alone produces meaningful and durable responses with manageable and reversible toxicity. This study supports the contention that high-dose IL-2 represents the treatment of choice in selected patients with advanced renal cell carcinoma.
MOPP/EBV/CAD hybrid chemotherapy with or without limited radiotherapy in advanced or unfavorably presenting Hodgkin's disease: a report from the Italian Lymphoma Study Group.

Published: February 2017

PURPOSE

We explored the feasibility, toxicity, and preliminary results of a chemotherapy (CT) regimen, mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)/epidoxirubicin, bleomycin, and vinblastine (EBV)/lomustine (CCNU), doxorubicin, and vindesine (CAD), derived through hybridization, shortening, and intensification of a corresponding 10-drug alternating combination CAD/MOPP/doxorubicin, bleomycin, and vinblastine (ABV), effective in treatment of advanced Hodgkin's disease (HD).

PATIENTS AND METHODS

Hybridization involved all drugs except CCNU and mechlorethamine, which were administered in alternating cycles; the length of therapy was reduced from nine to six cycles. The average projected drug doses during the six cycles were increased by 42%, with an overall 1.54 dose-intensification; epidoxorubicin was substituted for doxorubicin at equivalent tumoricidal doses. Radiotherapy (RT) was optional and its indications were limited.

RESULTS

Eighty assessable patients with previously untreated, advanced or unfavorably presenting HD were treated in nine cooperating institutions between 1988 and 1991. RT was delivered to 22 patients. Remissions were complete (CR) in 75 patients (93%), partial in three (4%), and null in two (3%). The median relative dose-intensity was 0.71 for the overall regimen. Three of five patients who failed to achieve CR, and two of the four who relapsed, received lower relative dose-intensive cycles. Nonhematologic toxicity was acceptable, but there was considerable hematologic toxicity. Fatal gastrointestinal bleeding was seen in one patient.

CONCLUSION

Caution is advised due to the short median follow-up period. Nevertheless, in addition to the excellent response rate, (1) the results were reached through abbreviation, intensification, and hybridization of an existing alternating regimen; (2) RT had limited use in this program, which may have contributed to lowering the risk of second tumors; and (3) the results were obtained in a multicenter study (a condition that often impairs results from clinical trials).

PURPOSE

A single-center, prospective, nonrandomized trial was conducted to evaluate therapeutic results of a short-term program of chemotherapy followed by locoregional radiotherapy in stage I or II intermediate/aggressive non-Hodgkin's lymphoma (NHL).

PATIENTS AND METHODS

From 1985 to 1990, 183 consecutive patients with a diagnosis of NHL (Working Formulation [WF] E through J excluding Burkitt's type), Ann Arbor stage I or II, and no more than three sites of disease involvement were treated with four cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy (six cycles in partial responders). Radiation therapy to initial sites of disease involvement (40 to 44 Gy) and to proximal uninvolved nodal region (36 Gy) was delivered shortly after completion of the chemotherapy program.

RESULTS

The complete remission (CR) rate was 98% at the end of combined therapy. Diagnostic excision of all measurable disease was performed in 33% of patients. In the remaining patients, 87% achieved CR with chemotherapy and 11% with radiation therapy, while three patients failed to achieve CR. After a median follow-up of 51 months, 26 patients have relapsed and 25 have died. The 5-year relapse-free and total survival rates were 83%. Aside from age older than 60 years, no other factor such as histology, stage, extranodal disease, bulky lymphoma, or abnormal lactic dehydrogenase (LDH) could predict for treatment outcome. There was a trend toward higher relapse rate for patients achieving CR at the time of radiation therapy (31%) as opposed to patients achieving CR with chemotherapy (15%) or with initial surgery (10%). Treatment was well tolerated and no deaths due to acute toxicity were observed.

CONCLUSION

For patients who present with limited-stage, aggressive NHL, a short course of CHOP chemotherapy followed by locoregional irradiation is safe, highly effective, and curative for most. Therefore, at the present time this approach can be regarded as standard therapy for these patients.
Antibody localization in human renal cell carcinoma: a phase I study of monoclonal antibody G250.
Authors: Oosterwijk E , Bander N H , Divgi C R , Welt S , Wakka J C , Finn R D , Carswell E A , Larson S M , Warnaar S O , Fleuren G J
Published: February 2017

PURPOSE

To define the imaging and biodistribution characteristics of iodine 131-labeled monoclonal antibody (mAb) G250 (131I-mAbG250), which recognizes a cell-surface antigen expressed by human renal cell carcinoma (RCC).

PATIENTS AND METHODS

G250 is a cell-surface antigen recognized by mAbG250 expressed by RCC but not detected in normal kidney. Clear-cell RCC, the most frequent form of RCC, shows homogeneous expression of G250, whereas non-clear-cell RCC and cancers derived from other organs generally do not express G250. Expression in normal tissues is highly restricted and limited to large bile ducts and gastric epithelium. 131I-mAbG250 was administered intravenously (IV) to 16 patients with RCC 7 to 8 days before surgery at five dose levels, with at least three patients entered at each dose level.

RESULTS

Clear tumor images were observed in 12 patients with G250-positive tumors and in one of three patients with G250-negative tumors. Imaged lesions in the peritoneal cavity were confirmed at surgery. The smallest lesion visualized was 8 mm in diameter. The specificity of 131I-mAbG250 localization to tumor tissue was established by radioactivity measurements, autoradiography, and immunohistochemistry of biopsied tissues, and technetium 99-human serum albumin blood-flow studies. The fraction of the injected 131I-mAbG250 dose per gram tumor (%ID/g tumor) localized in G250-positive tumors showed a broad range, but reached levels as high as 0.02% to 0.12%.

CONCLUSION

131I-mAbG250 localized specifically to G250 antigen-positive RCC and seems to have considerable potential as an imaging agent in RCC patients. 131I-mAbG250 uptake in the tumors, relative as well as absolute, are among the highest reported for tumor biopsies obtained 8 days after IV mAb administration. Based on the specific localization and high accumulation, mAb G250 may have therapeutic potential.
