Phase II study of prolonged oral etoposide in combination with intravenous cisplatin in advanced non-small cell lung cancer.
The objectives of the study were to evaluate the combination of cisplatin and prolonged oral etoposide for response rate, survival, and toxicity. The treatment regimen consisted of etoposide (50 mg/m2/day) p.o. for 21 consecutive days and cisplatin (100 mg/m2) i.v. on day 1 every 28 days for up to six courses. Patients with Stage IIIB or IV non-small cell lung cancer who had not received prior chemotherapy and had an ECOG performance status of 0-2 were eligible if they had normal bone marrow, liver and renal functions. Patients were followed weekly for toxicity including complete blood counts. The total number of patients entered in the study was 60, of whom 56 were male and four female, 40 white and 20 African Americans. Median age was 64 years (range, 39-77). Performance status 0, 1, and 2 was present in five, 39, and 16 patients, respectively. Fourteen patients had Stage IIIB and 46 Stage IV disease. A total of 142 treatment courses were administered (median 2, range 1-6). Three patients had a complete response and 19 patients had a partial response for an objective response rate of 37% (95% confidence interval, 31-43%). Median survival was 5 months (range, 1-39+). Neutropenia was the major toxicity with Grade 4 occurring in 25 patients after the first course. The following percent of patients experienced severe or life-threatening hematologic toxicity (Grade 3 and 4 combined) over all courses: leukopenia, 73%; neutropenia, 73%; anemia, 42%; and thrombocytopenia, 37%. Three patients died of neutropenic sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)
