ABSTRACT: In order to explore the activity of a combination of vinorelbine (VNL) and alternating cisplatin (CDDP) and ifosfamide (IFX) in non-small cell lung cancer (NSCLC), a phase II study was performed. Seventy chemoradiotherapy naive patients with NSCLC, stage IIIA, IIIB and IV disease, PS (ECOG) </=2, were treated with CDDP 40 mg/m(2) on days 1, 2, 3, IFX 1,800 mg/m(2) on days 22, 23, 24 and VNL 30 mg/m(2) on days 1, 8, 22, 29 every 6 weeks up to 6 courses. In the 67 evaluable patients, an objective response rate was observed in 47.8 +/- 12% (95% CI) with complete responses in 6%; responses occurred more frequently in patients with locally advanced disease (stage IIIA/IIIB) and/or performance status 0. The median duration of survival was 12 months: 19.9 months in stage III patients who received an integrated treatment and 10 months in metastatic disease. The median time to treatment failure was 10.5 months. Toxicity was mainly hematological, even though it was not dose-limiting and easily manageable. This combination seems to be active, and the good safety profile is probably the result of the use of an alternating schedule of CDDP and IFX. Median overall survival was also encouraging in stage IV disease. The prolongation of survival obtained when surgery and/or radiotherapy is applicable needs confirmation through a larger study.

ABSTRACT: Although many drug combination therapies have been proposed, there is no standard therapy for patients with advanced gastric carcinoma. The superiority of combination therapy over monochemotherapy has not been demonstrated convincingly. To explore the role of monochemotherapy, the authors evaluated 5-fluorouracil (5-FU), modulated by 6S-leucovorin (6S-LV) and a cisplatin-containing regimen, which was comprised of epirubicin, etoposide, and cisplatin with the addition of the reversal agent lonidamine (EEP-L).
After stratification according to performance status (PS) and resection of the primary tumor, 72 patients with advanced gastric carcinoma were randomized to 2 parallel Phase II trials with 5-FU/6S-LV and EEP-L, respectively. Thirty-six patients in Study A received bolus 6S-LV, 100 mg/m2, followed by bolus 5-FU, 370 mg/m2, on Days 1-5 and 36 others in Study B received epirubicin, 30 mg/m2, on Days 1 and 5; etoposide, 100 mg/m2, on Days 1, 3, and 5; cisplatin, 30 mg/m2, on Days 2 and 4; and lonidamine, 150 mg/day.
There were 6 partial responses (18.2%) (95% confidence interval [CI] +/- 13.2) in Study A and 7 partial responses (21.9%) (95% CI +/- 14.3) in Study B. Partial responses were more frequent in patients with resected tumors or with an Eastern Cooperative Oncology Group PS of 0-1. The median duration of response was 8.8 and 8.3 months, respectively, in Study A and Study B. The median survival reached 8 months in Study A and 9 months in Study B. In the whole population of patients survival was significantly higher in patients with a PS of 0-1 (P < 0.05). Patients with a PS of 0-1 and a resected tumor had the significantly longest survival both in EEP-L treated patients and in all evaluable patients in the two studies. The most frequent World Health Organization Grade 3-4 toxic effects were gastrointestinal in Study A and hematologic in Study B. No treatment-related death was observed.
The efficacy of 5-FU, modulated with 6S-LV, is moderate in patients with advanced gastric carcinoma, similar to cisplatin-containing regimens. PS and other prognostic factors could influence the response rate, which does not appear to be a reliable parameter for evaluating the outcome of chemotherapy trials.
