BACKGROUND: For patients with locally or regionally advanced non-small-cell lung cancer radiation is the standard treatment, but survival remains poor. We therefore conducted a randomized trial to determine whether induction chemotherapy before irradiation improves survival. METHODS: All the patients had documented non-small-cell cancer of the lung with Stage III disease established by clinical or surgical staging. Eligibility requirements included excellent performance status, minimal weight loss, and visible disease on radiography. Patients randomly assigned to group 1 received cisplatin (100 mg per square meter of body-surface area given intravenously on days 1 and 29) and vinblastine (5 mg per square meter given intravenously on days 1, 8, 15, 22, and 29) and then began radiation therapy on day 50 (60 Gy over a 6-week period). Patients assigned to group 2 received the same radiation therapy but began it immediately and received no chemotherapy. RESULTS: The eligible patients in group 1 (n = 78) and group 2 (n = 77) were comparable in terms of age (median, 60 years), sex, performance status, histologic features, stage of disease, and completeness of radiation therapy. The median survival was greater for those in group 1-13.8 versus 9.7 months (P = 0.0066 by log-rank test). Rates of survival in group 1 were 55 percent after one year, 26 percent after two years, and 23 percent after three years, as compared with 40, 13, and 11 percent, respectively, in group 2. Those in group 1 had a higher incidence of serious infections requiring hospitalization (7 percent, vs. 3 percent in group 2) and severe weight loss (14 percent vs. 6 percent), but there were no treatment-related deaths. CONCLUSIONS: In patients with Stage III non-small-cell lung cancer, induction chemotherapy with cisplatin and vinblastine before radiation significantly improves median survival (by about four months) and doubles the number of long-term survivors, as compared with radiation therapy alone. Since three quarters of the patients still die within three years, however, further improvements in systemic and local therapy are needed.

BACKGROUND AND METHODS: MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) has been the standard treatment for Hodgkin's disease for almost 20 years. In a randomized, multicenter trial, we compared three regimens of primary systemic therapy for newly diagnosed advanced Hodgkin's disease in Stages IIIA2, IIIB, and IVA or IVB: (1) MOPP alone given for 6 to 8 cycles, (2) MOPP alternating with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) for 12 cycles, and (3) ABVD alone for 6 to 8 cycles. Patients in a first relapse after radiation therapy were eligible. No additional radiation therapy was given. Patients who did not have a complete response or who had a relapse with either MOPP alone or ABVD alone were switched to the opposite regimen. RESULTS: Of 361 eligible patients, 123 received MOPP, 123 received MOPP alternating with ABVD, and 115 received ABVD alone. The patients were stratified according to age, stage, previous radiation, histologic features, and performance status. The overall response rate was 93 percent, with complete responses in 77 percent: 67 percent in the MOPP group, 82 percent in the ABVD group, and 83 percent in the MOPP-ABVD group (P = 0.006 for the comparison of MOPP with the other two regimens, both of which contained doxorubicin). The rates of failure-free survival at five years were 50 percent for MOPP, 61 percent for ABVD, and 65 percent for MOPP-ABVD. Age, stage (III vs. IV), and regimen influenced failure-free survival significantly. Overall survival at five years was 66 percent for MOPP, 73 percent for ABVD, and 75 percent for MOPP-ABVD (P = 0.28 for the comparison of MOPP with the doxorubicin regimens). MOPP had more severe toxic effects on bone marrow than ABVD and was associated with greater reductions in the prescribed dose. CONCLUSIONS: In this trial, ABVD therapy for 6 to 8 months was as effective as 12 months of MOPP alternating with ABVD, and both were superior to MOPP alone in the treatment of advanced Hodgkin's disease. ABVD was less myelotoxic than MOPP or ABVD alternating with MOPP.

PURPOSE: A previously reported randomized intergroup trial demonstrated that combination chemotherapy with methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC) was superior to single-agent cisplatin in patients with advanced urothelial carcinoma. We conducted a long-term analysis of patients included in the intergroup trial to examine factors associated with long-term survival. PATIENTS AND METHODS: Two-hundred fifty-five assessable patients with urothelial carcinoma were randomized to receive either single-agent cisplatin (70 mg/m2 on day 1) or combination chemotherapy with methotrexate (30 mg/m2 on days 1, 15, and 22), vinblastine (3 mg/m2 on days 2, 15, and 22), doxorubicin (30 mg/m2 on day 2), and cisplatin (70 mg/m2 on day 2). Courses were repeated every 28 days. The association between patient characteristics and survival was assessed using Cox proportional hazards models. RESULTS: With long-term follow-up evaluation, survival in the M-VAC arm continues to be superior to cisplatin (P = .00015, log-rank test). Predictors of survival include performance status, histology, and the presence of liver or bone metastasis. Only 3.7% of the patients randomized to M-VAC are alive and continuously disease-free at 6 years. CONCLUSION: Long-term follow-up evaluation of the intergroup trial confirms that M-VAC is superior to single-agent cisplatin in patients with advanced urothelial carcinoma; however, durable progression-free survival is rare. Patients with non-transitional-cell histology, poor performance status, and/or bone or visceral involvement fare poorly and are unlikely to benefit significantly from M-VAC chemotherapy.
