As compared with conventional chemotherapy, treatment with high-dose chemotherapy and autologous bone marrow transplantation increases event-free and overall survival in patients with chemotherapy-sensitive non-Hodgkin's lymphoma in relapse.

Cytokines are active in a few patients with metastatic renal-cell carcinoma. The higher response rate and longer event-free survival obtained with a combination of cytokines must be balanced against the toxicity of such treatment.

Adult patients with advanced non-Hodgkin's lymphoma in whom conventional chemotherapy has failed are seldom cured thereafter. We studied 100 such patients with intermediate-grade or high-grade non-Hodgkin's lymphoma who were subsequently treated with high-dose chemotherapy (61 patients) or high-dose chemotherapy plus total-body irradiation (39 patients), with bone marrow transplantation used for hematologic support. Thirty-four patients had disease that had been refractory to primary chemotherapy, and 66 patients had had a complete remission with primary chemotherapy but later relapsed. Before autologous bone marrow transplantation and high-dose chemotherapy, the 66 relapsed patients had also received conventional salvage chemotherapy; 22 had had no response or had had disease progression (a response termed "resistant relapse"), and 44 patients had responded partially or completely (a response termed "sensitive relapse"). After high-dose therapy and bone marrow transplantation, the actuarial three-year disease-free survival was zero in the refractory group, 14 percent in the resistant-relapse group, and 36 percent in the sensitive-relapse group. Patients who had had a complete remission in response to initial chemotherapy had a higher disease-free survival rate than those who had not (P less than 0.001), and patients with sensitive relapse had a higher disease-free survival rate than those with resistant relapse (P less than 0.003). These results should be considered in the planning or interpretation of trials of salvage chemotherapy in adults with non-Hodgkin's lymphoma.

Purpose: (1) To improve survival rates in patients with Ewing's sarcoma (ES) or peripheral neuroectodermal tumours (PNET) using semi-continuous chemotherapy and aiming to peform surgery in all; (2) To identify early prognostic factors to tailor therapy for future studies. Patients and methods One hundred and forty-one patients were entered onto the trial between January 1988 and December 1991. Induction therapy consisted of five courses of Cytoxan, 150 mg/m2 × 7 days, followed by Doxorubicin, 35 mg/m2 i.v on day 8 given at short intervals. Surgery was recommended whenever possible. The delivery of radiation therapy was based on the quality of resection and the histological response to CT. Maintenance chemotherapy consisted of vincristine + actinomycin and cytoxan + doxorubicin. The total duration of therapy was 10 months. Results After a median follow-up of 8.5 years, the projected overall survival at 5 years was 66% and disease-free survival (DFS) was 58%. In patients treated by surgery, only the histological response to CT had an influence on survival: 75% DFS for patients with a good histological response (less than 5% of cells), 48% for intermediate responders and only 20% for poor responders (≥ 30% of cells), P < 0.0001. The initial tumor volume by itself had no influence on DFS in these patients. In contrast, the tumour volume had a strong impact on DFS in patients treated by radiation therapy alone. Age had no impact on outcome. Conclusion Therapeutic trials for localized Ewing's sarcoma should be based on the histological response to chemotherapy or on the tumour volume according to the modality used for local therapy. © 2001 Cancer Research Campaign http://www.bjcancer.com

We investigated the possible causative role of interleukin 6 (IL-6) in the paraneoplastic inflammatory syndrome and in paraneoplastic cholestasis (Stauffer syndrome) associated with renal-cell carcinoma in a series of 119 patients with metastases. IL-6 levels were found significantly higher in patients with paraneoplastic fever and weight loss. Patients with detectable serum IL-6 (n 5 90, 76%) had significantly higher serum CRP, haptoglobin, and serum alkaline-phosphatase and gammaglutamyl-transferase levels. Platelets, polymorphonuclear neutrophil (PMN) and monocyte counts were also significantly higher in patients with detectable serum IL-6; in contrast, hemoglobin levels were significantly lower in patients with serum IL-6 over 80 pg/ml. Three of these patients were included in a phase-II trial of an anti-IL-6 monoclonal antibody given daily during 21 days. Reductions of CRP, haptoglobin and serum alkalin phosphatases were observed in all 3 patients during anti-IL-6 administration, with a subsequent increase up to or above pre-treatment levels after the end of anti-IL-6. Decrease of platelets, PMN and monocyte counts were also observed in the 3 patients during anti-IL-6 administration, with a normalization of cell counts in a patient with increased platelets, PMN and monocyte counts. Hemoglobin concentration, serum albumin concentration and lymphocyte counts remained stable in the 3 patients during and after anti-IL-6 administration. Serum IL-6, as evaluated by IRMA, decreased in the 3 patients during anti-IL-6 administration, but increased above pre-treatment levels after the end of anti-IL-6 administration. These results demonstrate that IL-6 is involved in the physiopathology of paraneoplastic syndromes observed in patients with metastatic renal-cell carcinoma, in particular CRP and haptoglobin increase, paraneoplastic cholestasis, also paraneoplastic thrombocytosis, neutrophilia and monocytosis.

Conformity with EBM was similar to previous reports. Elaboration of treatment strategy within a formal multidisciplinary staff and treatment within a cancer network are both important prognostic factors for optimal clinical care.

From April 1984 to December 1987, the French Pediatric Oncology Society (SFOP) organized a randomized trial for advanced-stage B-cell lymphoma without CNS involvement to study the possibility of reducing the length of treatment to 4 months. After receiving the same three intensive six-drug induction courses based on high-dose fractionated cyclophosphamide, high-dose methotrexate (HD MTX), and cytarabine in continuous infusion, patients were evaluated for remission. Those who achieved complete remission (CR) were randomized between a long arm (five additional courses with two additional drugs; 16 weeks of treatment) and a short arm (two additional courses; 5 weeks). For patients in partial remission (PR), intensification of treatment was indicated. Two hundred sixteen patients were registered: 15 stage II nasopharyngeal and extensive facial tumors, 167 stage III, and 34 stage IV, 20 of the latter having more than 25% blast cells in bone marrow. The primary sites of involvement were abdomen in 172, head and neck in 30, thorax in two, and other sites in 12. One hundred sixty-seven patients are alive in first CR with a minimum follow-up of 18 months; four are lost to follow-up. Eight patients died from initial treatment failure, 14 died from toxicity or deaths unrelated to tumor or treatment, and 27 relapsed. The event-free survival (EFS), with a median follow-up of 38 months, is 78% (SE 3) for all the patients, 73% (SE 11) for the stage II patients, 80% (SE 3) for the stage III patients, and 68% (SE 8) for the stage IV and acute lymphoblastic leukemia (ALL) patients. One hundred sixty-six patients were randomized: 82 in the short arm and 84 in the long arm. EFS is, respectively, 89% and 87%. Statistical analysis confirms equivalence of both treatment arms with regard to EFS. Moreover, morbidity was lower in the short arm. This study confirms the high survival rate obtained in the previous LMB 0281 study without radiotherapy or debulking surgery and demonstrates the effectiveness of short treatment.
