Phase II study of epirubicin, mitomycin C, and 5-fluorouracil in hormone-refractory prostatic carcinoma.

Management of metastatic prostatic carcinoma when it becomes refractory to hormonal therapy is controversial, and no standard treatment exists. Nevertheless, chemotherapy for hormone-refractory prostatic carcinoma (HRPC) has shown some advantages compared with the best supportive care. In a prospective phase II study, we evaluated the combination of epirubicin (E), mitomycin C (MMC), and 5-fluorouracil (5-FU) in patients with HRPC. Twenty-eight patients with HRPC were treated with a combination of E (30 mg/m2), 5-FU (750 mg/m2), and MMC (5 mg/m2) day 1 and 2, every 4 weeks. Treatment was continued until evidence of disease progression or excessive toxicity. Patients were monitored with serial measurements of prostate-specific antigen (PSA). Forty-seven percent of the patients exhibited a reduction of serum PSA concentration and an objective response; 38% exhibited disease stability, and 15% had disease progression. Toxicity was substantial. The median time to progression was 7.3 months (range, 1.7-16.8 months) and median survival was 14.5 months (range, 1.6-38.4 months). Performance status improved in 80% of patients, and bone pain was relieved in 70%. Thus the combination of E, MMC, and 5-FU shows activity in the treatment of HRPC, giving substantial palliation of symptoms. In one patient, PSA values remained low even when the tumor had progressed.

Carboplatin, vindesine, 5-fluorouracil-leucovorin and 13-cis retinoic acid in the treatment of advanced non-small cell lung cancer. A phase II study.

PURPOSE: Carboplatin, vindesine and 5-fluorouracil/leucovorin are drugs active in the treatment of non-small cell lung cancer (NSCLC) and they can be administered in an outpatient setting. Retinoids, which are widely used agents in chemoprevention, have been reported to exert (in vitro models) growth inhibitory effects of synergistic type with chemotherapy, and differentiating effects on NSCLC cells. PATIENTS AND METHODS: 28 patients with advanced NSCLC with measurable disease were entered into the trial. Eligibility criteria included performance status < or = 3 and adequate renal and liver function. Patients with brain metastases were not excluded. Treatment was as follows: Carboplatin (CBCDA) 300 mg/m2 day 1, Vindesine (VDS) 3 mg/m2 days 1 and 5, leucovorin (L) 100 mg/m2, 5-fluorouracil (5-FU) 370 mg/m2 for 5 days and 13-cis retinoic acid (R) 1 mg/kg, administered between chemotherapy courses. After 6 courses of chemotherapy responders were maintained with R, until progression. RESULTS: 120 courses of chemotherapy have been delivered (median 4 courses per patient, range 1 to 6). All patients were evaluable for response and toxicity. Objective responses: 2 complete responses (CR) (7%), 9 partial responses (PR) (32%), 9 stable disease (SD) (32%), 8 progressive disease (PD) (29%). (Response rate 39%, 95% CI: 22% to 60%). Median time to progression was 7.7 months (range 3.4-22) and median survival was 9.7 months (range 0.5-27) with 40% of patients alive after one year. Toxicity WHO: hematological grade 3-4 in 46% of patients, grade 2 diarrhea in 21% of patients, ileus in 14% of patients, Neurologic grade 2 in 11% of patients. CONCLUSIONS: The addition of RA to CBDCA, VDS, FU, L, R represents an effective treatment in NSCLC, with manageable toxicity.

[Importance of a multidisciplinary approach to metastatic cancer of the rectum]. / Intérêt d'une approache multidisciplinaire des cancers du rectum initialement métastatiques.

Management of rectal cancers with synchronous metastasis is difficult. We evaluated in 23 patients a combination of pelvic radiotherapy at the dose of 45 Gy in 5 weeks and 25 fractions with chemotherapy by 5-fluorouracil (350 mg/m2/day) and folinic acid (20 mg/m2/day) for 5 days at the time of the first and the fifth week of the irradiation. Surgery was indicated firstly in cases of stricture or secondarily for resection of the primary location and, when possible, of the metastasis. General state of health of the patients improved in 35%, symptomatology in 86% and comfort in 72% of the cases. Response rates for the primary tumor were 41% of partial response and 50% of stable disease. For the metastatic lesions, they were 9% and 59% respectively. Sixty-one per cent of patients were secondarily operated with resection of the primary tumor in 12 cases and of hepatic metastases in 2 cases. The median survival and the median survival without progression were respectively 13 and 9 months. Radiochemotherapy combination as the first treatment was beneficial in 4/5 of the patients presenting a rectal cancer with synchronous metastasis and allowed us to select those that would secondarily benefit from a surgical resection.
