PURPOSE: A prospective randomized phase III clinical trial was conducted to assess whether the addition of tamoxifen (TAM) to the three-agent regimen of cisplatin (CDDP), dacarbazine (DTIC), and carmustine (BCNU) significantly increased the progression-free survival and overall survival of patients with advanced malignant melanoma. PATIENTS AND METHODS: Patients with advanced malignant melanoma were treated with CDDP + DTIC + BCNU (CDB) with or without TAM. The dose schedule was CDDP 25 mg/m2 given intravenously (IV) for 30 to 45 minutes in 500 mL of dextrose and ½ normal saline (NS) on days 1 to 3 of a 3-week cycle; DTIC 220 mg/m2 IV for 1 hour in 500 mL of dextrose and ½ NaCl on days 1 to 3 of a 3-week cycle; BCNU 150 mg/m2 IV for 2 to 3 hours in 750 to1,000 mL of dextrose and 5% water onday 1 of every odd 3-week cycle; and TAM 20 mg taken orally every morning. RESULTS: There were 184 eligible patients enrolled. These patients were observed until death or for a minimum of 1.3 years. At last contact, 12 were still alive. The median time to progression was 3.4 months on the CDB arm and 3.1 months on the CDB + TAM arm. The median survival time was 6.8 months with CDB and 6.9 months with CDB + TAM. Progression-free survival (P = .429) and overall survival (P = .545) were not found to differ by treatment. CONCLUSION: The addition of TAM to this three-agent regimen of CDB was not found to provide a meaningful clinical advantage in the treatment of patients with advanced malignant melanoma.

Purpose Patients with newly diagnosed, advanced-stage, follicular grade 1 non-Hodgkin's lymphoma (NHL) are often asymptomatic and can be observed without immediate chemotherapy. The goals of this study were to assess the overall response rate (ORR) to rituximab in this patient population and to determine the time-to-progression (TTP) and time-to-subsequent-chemotherapy (TTSC). Patients and Methods Eligible patients had untreated follicular grade 1 NHL, and measurable stage III/IV disease. Patients received rituximab 375 mg/m2 intravenous weekly × 4 doses and were then followed for response and progression; no maintenance therapy was provided. Results Thirty-seven patients were accrued; one patient was ineligible. The median age was 59 years (range, 29 to 83 years). Six patients (18%) had elevated lactate dehydrogenase levels. The ORR was 72%, with 36% complete remissions. Fourteen (39%) of 36 patients remain in unmaintained remission, two died without disease progression, and three died with disease progression. Twenty (56%) of 36 patients have disease progression. The median TTP was 2.2 years (95% CI, 1.3 to not yet reached). Eighteen patients have subsequently been treated with chemotherapy, with a median TTSC of 2.3 years (95% CI, 1.6 to not yet reached). Patients with a high lactate dehydrogenase level had a lower ORR of 33% and a short TTP of only 6 months. Conclusion Rituximab can be safely administered to patients with advanced-stage follicular grade 1 NHL with efficacy and minimal toxicity. This therapy is highly active and offers an acceptable alternative to observation in this patient population. Patients with high LDH should not be considered for rituximab monotherapy.
