A Study of Oral Etoposide, Infusional Cisplatin, and Infusional 5-Fluorouracil for Locally Advanced or Metastatic Non-Small-Cell Lung Cancer

A combination of oral etoposide, infusional cisplatin (24-hr) and infusional 5-fluorouracil (5-day) was used to treat 87 patients with non-small-cell lung cancer in a Phase II trial. Twenty-six patients were Stage IIIB, and 61 patients were Stage IV (new international classification). The regimen was well tolerated, with 49% grade 3 or 4 toxicities of all types. Response rates, partial and complete, were 40%, (95% confidence interval: 30%, 51%) for Stage IV patients and 20% (95% confidence interval: 10%, 32%), in Stage IIIB. An additional 68% of patients in Stage IIIB and 45% of patients in Stage IV achieved stable disease and had a median survival of 8.8 months, similar to that of patients in partial remission. Median survival was 5.6 months (95% confidence interval: 4.4 months, 10.8 months) for Stage IV patients and 11.0 months (95% confidence interval: 8.8 months, 12.4 months), for Stage IIIB. Of interest was the finding of a higher response rate in patients with a shorter duration of symptoms (less than 6 months versus greater than 6 months).
