Popis: In a series of 46 symptomatic patients with metastatic, stage IV, non-small-cell lung cancer (NSCLC), we used a three-drug combination with cisplatin (120 mg/m2), vinblastine (6 mg/m2) and mitomycin-C (6 mg/m2) (PVM), repeated every 3 weeks. After two courses, we observed that none of the patients had achieved a complete response; 33% (15/46) had partial response (95% confidence limits: 19.2-46.8); 39% (18/46), stable disease and 28% (13/46), progressive disease. Median response duration was 14.0 weeks (range, 4-36.7), median time to progression 22.4 weeks (range, 7-44.4), and median survival time 26.4 weeks (range, 1-103). WHO grade III-IV myelotoxicity occurred in 15.2% of the courses administered, affecting 39.5% of patients, and severe nephrotoxicity was observed in 9.3% of patients. No toxic death occurred. The post-treatment KPS score increased in 7 patients with partial response (47%), 4 with stable disease (22%) and 1 with progressive disease (8%), while it decreased in 3 patients with partial response (20%), 3 with stable disease (17%) and 10 with progressive disease (77%). In all, KPS increased in 12/46 cases (26%). However, no statistically significant difference was observed when the KPS score before and after treatment was compared in the total group of patients or when it was compared in the total group of patients or when it was compared in responders and in non-responders. After chemotherapy, there was complete disappearance of at least one symptom in 27.1% of cases and improvement in 27.1%. Overall, major symptom control occurred in 54.3% of cases, with a median palliation time lasting 10 weeks (range, 4-32). Patients with partial remission and stable disease achieved symptomatic palliation in 90% and 55.5% of cases, respectively. When we compared the palliation rate between responders and non-responders, a significant difference was noted (Chi-square test: P0.05). Although our schedule did not produce a higher objective response rate and the KPS score was not significantly improved, the symptom palliation appeared worthwhile considering the highly unfavourable prognosis of the patients investigated.
