PURPOSE The CD20 B-lymphocyte surface antigen expressed by B-cell lymphomas is an attractive target for radioimmunotherapy, treatment using radiolabeled antibodies. We conducted a phase I dose-escalation trial to assess the toxicity, tumor targeting, and efficacy of nonmyeloablative doses of an anti-CD20 monoclonal antibody (anti-B1) labeled with iodine-131 (131I) in 34 patients with B-cell lymphoma who had failed chemotherapy. PATIENTS AND METHODS Patients were first given tracelabeled doses of 131I-labeled anti-B1 (15 to 20 mg, 5 mCi) to assess radiolabeled antibody biodistribution, and then a radioimmunotherapeutic dose (15 to 20 mg) labeled with a quantity of 131I that would deliver a specified centigray dose of whole-body radiation predicted by the tracer dose. Whole-body radiation doses were escalated from 25 to 85 cGy in sequential groups of patients in 10-cGy increments. To evaluate if radiolabeled antibody biodistribution could be optimized, initial patients were given one or two additional tracer doses on successive weeks, each dose preceded by an infusion of 135 mg of unlabeled anti-B1 one week and 685 mg the next. The unlabeled antibody dose resulting in the most optimal tracer biodistribution was also given before the radioimmunotherapeutic dose. Later patients were given a single tracer dose and radioimmunotherapeutic dose preceded by infusion of 685 mg of unlabeled anti-B1. RESULTS Treatment was well tolerated. Hematologic toxicity was dose-limiting, and 75 cGy was established as the maximally tolerated whole-body radiation dose. Twenty-eight patients received radioimmunotherapeutic doses of 34 to 161 mCi, resulting in complete remission in 14 patients and a partial response in eight. All 13 patients with low-grade lymphoma responded, and 10 achieved a complete remission. Six of eight patients with transformed lymphoma responded. Thirteen of 19 patients whose disease was resistant to their last course of chemotherapy and all patients with chemotherapy-sensitive disease responded. The median duration of complete remission exceeds 16.5 months. Six patients remain in complete remission 16 to 31 months after treatment. CONCLUSION Nonmyeloablative radioimmunotherapy with 131I-anti-B1 is associated with a high rate of durable remissions in patients with B-cell lymphoma refractory to chemotherapy.
Malignant mesothelioma following treatment for Hodgkin's disease.

Published: February 2017

PURPOSE Asbestos exposure is the major known risk factor for mesothelioma, but several case reports have suggested a link between radiation therapy and subsequent development of malignant mesothelioma. This report explores a possible association between radiation therapy for Hodgkin's disease and mesothelioma. PATIENTS AND METHODS Four cases of malignant mesothelioma were observed following Hodgkin's disease at the Mesothelioma Clinic of the Dana-Farber Cancer Institute. A fifth such patient was found after a review of the literature. RESULTS In all five cases, the mesothelioma arose in the field of prior radiotherapy. No history of asbestos exposure was elicited by careful questioning or by review of chest radiographs. Examination of lung tissue in one patient showed 250 ferruginous bodies per gram of lung tissue, consistent with no significant prior exposure. The mean interval between radiation treatment for Hodgkin's disease and development of mesothelioma was 15 years, which emphasizes the need for continued follow-up and evaluation of these patients and supports a causal relationship. CONCLUSION Mesothelioma may need to be added to the list of second malignancies that arise following radiation therapy for Hodgkin's disease. Further support is given to a causal link between radiation exposure and mesothelioma.

PURPOSE Since cladribine (2-chlorodeoxyadenosine [2-CdA]) and mitoxantrone both exhibit major activity against indolent lymphoid malignancies and have different mechanisms of action, we performed a dose-escalation study of 2-CdA and mitoxantrone in patients with alkylator-failed indolent lymphoma to determine the maximum-tolerated dose (MTD) of this combination and to make preliminary observations about efficacy. PATIENTS AND METHODS Twenty-three patients were treated every 28 to 35 days, in cohorts of at least three patients, with stepwise dose escalations until dose-limiting toxicities (DLTs) were encountered. The initial dose levels were 2-CdA 0.1 mg/kg/d by continuous infusion for 7 days, mitoxantrone 5 mg/m2 intravenously (i.v.) on day 1, and prednisone 100 mg/d on days 1 to 5. Mitoxantrone was dose-escalated in increments of 2.5 mg/m2 i.v. on day 1. RESULTS The MTD of the combination was 2-CdA 0.1 mg/kg/d for 7 days, mitoxantrone 7.5 mg/m2 i.v. on day 1, and prednisone 100 mg/d on days 1 to 5. Myelosuppression and infection were the DLTs. The recommended phase II doses were 2-CdA 0.075 mg/kg/d for 7 days mitoxantrone 5 mg/m2 i.v. on day 1; prednisone was omitted to decrease the risk of opportunistic infections. The overall response rate was 70%, with 22% complete responses (CRs) and 48% partial responses (PRs). The median duration of CR was 15 months and PR 5 months. CONCLUSION These results demonstrate the feasibility and safety of combining 2-CdA and mitoxantrone in the treatment of indolent lymphoma, and appear to confirm clinically the mechanistic synergism and rationale for this combination regimen. Prednisone exacerbated the risk of opportunistic infection and was omitted. The overall response rate was high, including durable CRs. Further studies of this combination regimen are warranted in untreated and alkylator-failed indolent lymphoma.

PURPOSE To assess the value of granulocyte-macrophage colony-stimulating factor (GM-CSF) for induction treatment of acute myeloid leukemia (AML), both for priming of leukemic cells and for acceleration of hematopoietic recovery. PATIENTS AND METHODS GM-CSF was administered 5 micrograms/kg/d by continuous intravenous (i.v.) infusion during induction therapy with daunorubicin (DNR) (days 1 to 3) and cytarabine (ARA-C) (days 1 to 7). A total of 102 patients were randomized onto four arms, as follows: (1) GM-CSF 24 hours before and during chemotherapy (arm +/-); (2) GM-CSF after chemotherapy until day 28 or recovery of polymorphonuclear leukocytes (PMNs) (arm -/+);(3) GM-CSF before, during, and after chemotherapy (arm +/+); or (4) no GM-CSF (arm -/-). Stopping rules were applied in case of an initial WBC count greater than 30 x 10(9)/L or a secondary increase of circulating blast cells. Analyses were performed according to the intention-to-treat principle. RESULTS The complete remission (CR) rates were 77% (arm -/-), 72% (arm +/-), 48% (arm -/+), and 46% (arm +/+). Patients randomized to receive GM-CSF after induction (arms -/+ and +/+) had a significantly lower CR rate (P = .008) and a trend toward accelerated recovery of neutrophils, but no fewer infections or induction deaths. The lower CR rate appeared to be related to an increased resistance rate, with persistent leukemia. The main side effects of GM-CSF were fluid retention and hypotension. CONCLUSION GM-CSF administered during induction treatment of AML with a DNR/Ara-C combination did not provide any clinical benefit. Furthermore, there was a significant decrease in the CR rate with more persistent leukemia when GM-CSF was administered during the hypoplastic phase after the chemotherapy courses.

PURPOSE Purine analogs have wide potential indications in the treatment of hematologic malignancies, but intravenous administration has been required. We previously established that the oral bioavailability of cladribine is 50%. Our aim was to evaluate the efficacy and toxicity of oral cladribine to previously untreated patients with chronic lymphocytic leukemia (CLL). PATIENTS AND METHODS Sixty-three patients with symptomatic but previously untreated CLL received cladribine solution 10 mg/m2/d orally for 5 consecutive days in monthly courses. RESULTS Complete remission (CR) was achieved in 24 patients (38%), and 23 patients (37%) had a partial response (PR). Most patients, including those in whom there was no remission (NR) achieved normal blood lymphocyte counts. Failure to meet response criteria was mostly due to thrombocytopenia. The median response duration was not reached at 2 years. The median survival time among 13 deceased patients was 322 days, whereas the median observation time of surviving patients is 760 days. The overall survival rate at 2 years is 82%. Response rate was associated with clinical stage. Grade III to IV infectious toxicity occurred in one third of patients. CONCLUSION Orally administered cladribine is an effective and feasible therapy for CLL, and produces durable remissions in three quarters of the patients. However, significant toxicity may occur and further studies are required to assess long-term effects and quality-of-life aspects.

PURPOSE To determine the long-term clinical course of patients with metastatic breast cancer (MBC) who achieved a complete remission with doxorubicin-alkylating agent-containing combination chemotherapy programs. PATIENTS AND METHODS To assess the long-term prognosis of MBC, we reviewed our experience with 1,581 patients treated on consecutive doxorubicin and alkylating agent-containing front-line treatment protocols between 1973 and 1982. Treatment was administered for a maximum duration of 2 years. Characteristics of long-term survivors were evaluated, and hazard rates for progression were calculated. RESULTS From this group, 263 (16.6%) achieved complete responses (CR) and 49 (3.1%) remained in CR for more than 5 years. After a median duration of 191 months, 26 patients remain in first CR, four patients died in CR at times ranging from 118 to 234 months, 18 patients died of breast cancer, and one is alive with metastatic disease. Compared with the overall CR and total patient populations, the long-term CR group had more premenopausal patients, a younger median age, a lower tumor burden, and better performance status. The hazard function shows a substantial drop in risk of progression after approximately 3 years from initiation of therapy. Ten long-term CR patients developed second primary cancers: breast (3), ovary (2), pancreas (1), endometrium (1), colon (1), head and neck (1), and lung (1). CONCLUSION Most patients with MBC treated with systemic therapies have only temporary responses to treatment, but some patients continue in CR following initial treatment. These data show that a small percentage of patients achieve long-term remissions with standard chemotherapy regimens. Remission consolidation strategies are needed.

PURPOSE To assess the comparative antiemetic efficacy of single-dose intravenous (IV) dolasetron mesylate and ondansetron in preventing cisplatin-induced nausea and vomiting. PATIENTS AND METHODS Cancer patients (n = 609) receiving first-course cisplatin chemotherapy were randomized to one of three treatments: 1.8 or 2.4 mg/kg dolasetron mesylate salt (equivalent to 1.3 and 1.8 mg/kg dolasetron base, respectively) or 32 mg ondansetron. Each treatment was infused over 15 minutes, 30 minutes before cisplatin administration. Patients were stratified to cisplatin doses of > or = 70 and less than 91 mg/m2 (n = 368) or > or = 91 mg/m2 (n = 241), administered over < or = 3 hours. Protocol-defined efficacy criteria included complete response (zero emetic episodes and no rescue medication), major response (1 to 2 emetic episodes and no rescue medication), and patients' report of nausea severity and satisfaction recorded on a 100-mm visual analog scale (VAS). RESULTS The three treatments met protocol-specified criteria for equivalence. Complete response rates for dolasetron mesylate 1.8 mg/kg, 2.4 mg/kg, and ondansetron, respectively, were 49.2%, 45.6%, and 50.4% for patients in the lower cisplatin stratum (mean, 74.7 mg/m2) and 36.8%, 31.3%, and 31.8% in the higher cisplatin stratum (mean, 100.6 mg/m2). No significant differences were observed in the extent of nausea with either dolasetron dose compared with ondansetron. Less nausea was noted with 1.8 mg/kg dolasetron compared with the 2.4 mg/kg dose (P = .044) All three antiemetic treatments were well tolerated. Asymptomatic electrocardiogram changes were recorded with both dolasetron and ondansetron. CONCLUSION A single IV dose of dolasetron mesylate (1.8 or 2.4 mg/kg) has comparable safety and efficacy to a single 32-mg IV dose of ondansetron in patients receiving cisplatin chemotherapy.

PURPOSE To assess the efficacy and toxicity of paclitaxel administered as a 3-hour infusion to patients with recurrent malignant glioma. PATIENTS AND METHODS Adult patients with recurrent malignant glioma following radiation therapy, who had received no more than one prior chemotherapy regimen and who had a Karnofsky performance status (KPS) > or = 60, were treated with a 3-hour infusion of paclitaxel every 3 weeks. The initial dose was 210 mg/m2; dose escalation to 240 mg/m2 was allowed. Tumor response was assessed at 6-week intervals using radiographic and clinical criteria. Treatment was continued until documented tumor progression or a total of 12 paclitaxel infusions. RESULTS Of 41 eligible patients, all were assessable for treatment toxicity and 40 (98%) were assessable for response. The response rate (disease stabilization or better) was 35%. Twenty-nine patients (71%) underwent dose escalation to 240 mg/m2 without the use of growth factors. Toxicities included alopecia (98%), nausea (22%), arthralgias (32%), CNS toxicity (24%), peripheral neuropathy (15%), cardiac toxicity (7%), and myelosuppression (10% grade 3 or 4 hematologic toxicity). No patient developed febrile neutropenia. There was one allergic reaction (2%). CONCLUSION Paclitaxel is well tolerated at this dose schedule in patients with recurrent malignant glioma, and affords a modest response rate. Because minimal myelotoxicity was encountered in our patients, a dose-escalating phase I/II study of paclitaxel is planned to determine the maximal-tolerated dose (MTD).

PURPOSE To determine the response rate and survival of chemotherapy-naive patients with extensive-stage small-cell lung cancer (SCLC) treated with topotecan, and to determine the relationship of topotecan pharmacokinetics with response and toxicity. PATIENTS AND METHODS Forty-eight patients with previously untreated, extensive-stage SCLC received 2.0 mg/m2 of topotecan daily for 5 days. The first 13 patients were treated without colony-stimulating factor (CSF) support; the next 35 patients received 5 micrograms/kg of granulocyte-colony-stimulating factor (G-CSF) for 10 to 14 days starting on day 6. Cycles were repeated every 3 weeks for a maximum of four cycles. Patients who had a partial response to topotecan after four cycles, stable disease after two cycles, or progressive disease at any time received salvage chemotherapy with cisplatin and etoposide. Topotecan pharmacokinetics were measured using a four-point sampling scheme. RESULTS Of 48 patients, none had a complete response and 19 had a partial response, for an objective response rate of 39% (95% confidence interval [CI], 25.2% to 53.0%). The median response duration was 4.8 months (95% CI, 3.0 to 7.3). After a median follow-up duration of 18.2 months, the overall median survival time was 10.0 months (95% CI, 8.2 to 12.7); the 1-year survival rate was 39% (95% CI, 25.2% to 53.0%). Eight of 34 patients (24%) who received salvage chemotherapy responded. Four of 17 patients who did not respond to first-line therapy with topotecan responded to cisplatin and etoposide. The most common toxicity was hematologic. Ninety-two percent of patients treated without G-CSF developed grade 3 or 4 neutropenia, compared with 29% who received G-CSF. However, the incidence of neutropenic fevers was similar between the two groups (8% and 11%, respectively), and one patient in each group died of neutropenic fevers. There were no differences in objective tumor response, duration of response, time to treatment failure, or survival between the 13 patients who entered the study before G-CSF administration was mandated and the 35 patients who entered after and received G-CSF. There was poor correlation between the WBC count and absolute neutrophil counts (ANCs) and both the area under the curve (AUC) and maximum concentration++ (Cmx) of total topotecan in plasma. There was no correlation between the tumor response and either AUC or Cmx of total topotecan. CONCLUSION The activity of topotecan in extensive-stage SCLC noted in this study warrants further investigation of this agent in phase III clinical trials.
Bronchioloalveolar carcinoma.
Authors: Barkley J E , Green M R 
Published: February 2017

PURPOSE To review bronchioloalveolar carcinoma (BAC). MATERIALS AND METHODS English language articles were identified through a Melvyl Medline Search (1966 to 1995) and through the bibliographies of selected articles. RESULTS An increase in BAC appears to be responsible for the observed rise in the incidence of adenocarcinoma of the lung. Patients with BAC tend to be younger at diagnosis, are more likely to be female, and less likely to be cigarette smokers when compared with other patients with non-small-cell lung cancer (NSCLC). The etiology of this disease is unclear, but multiple environmental insults have been implicated. There are three subtypes of BAC and the symptoms and prognosis of the disease depend on the subtype and extent of disease, but are generally similar to other histologic types of NSCLC. The radiographic differential diagnosis is broad and includes both benign and malignant diseases. The treatment approach to patients with BAC is similar to those with other types of NSCLC. CONCLUSION BAC appears to be increasing in incidence, especially in young, nonsmoking females. Three subtypes of the disease exist and are responsible for the variable clinical presentations. Further epidemiologic investigation is needed to elucidate the etiology and pathogenesis of this unique disease.

PURPOSE To propose a classification of the acute emetogenicity of antineoplastic chemotherapy agents, and to develop an algorithm to define the emetogenicity of combination chemotherapy regimens. METHODS A Medline search was conducted to identify (1) clinical trials that used chemotherapy as single-agent therapy, and (2) major reviews of antiemetic therapy. The search was limited to patients who received commonly used doses of chemotherapy agents, primarily by short (< 3 hours) intravenous infusions. Based on review of this information and our collective clinical experience, we assigned chemotherapy agents to one of five emetogenic levels by consensus. A preliminary algorithm to determine the emetogenicity of combination chemotherapy regimens was then designed by consensus. A final algorithm was developed after we analyzed a data base composed of patients treated on the placebo arms of four randomized antiemetic trials. RESULTS Chemotherapy agents were divided into five levels: level 1 (< 10% of patients experience acute [< or = 24 hours after chemotherapy] emesis without antiemetic prophylaxis); level 2 (10% to 30%); level 3 (30% to 60%); level 4 (60% to 90%); and level 5 (> 90%). For combinations, the emetogenic level was determined by identifying the most emetogenic agent in the combination and then assessing the relative contribution of the other agents. The following rules apply: (1) level 1 agents do not contribute to the emetogenic level of a combination; (2) adding > or = one level 2 agent increases the emetogenicity of the combination by one level greater than the most emetogenic agent in the combination; and (3) adding level 3 or 4 agents increases the emetogenicity of the combination by one level per agent. CONCLUSION The proposed classification schema provides a practical means to determine the emetogenic potential of individual chemotherapy agents and combination regimens during the 24 hours after administration. This system can serve as a framework for the development of antiemetic guidelines.
