Abstract

PURPOSE: To evaluate the efficacy and safety of gemcitabine, a pyrimidine antimetabolite against advanced non-small cell lung cancer (NSCLC).
MATERIALS AND METHODS
Forty patients with unresectable stage IIIb to IV, pathologacally documented NSCLC were evaluated. Patients received gemcitabine 1000 mg/m, as a 30 to 60-min, intravenous infusion on days 1, 8 and 15, which was repeated every 28 days. Responses were assessed every two courses. Twenty-five to fifty percent dose reduction was permitted, ptovided that overall toxicity was severe according to World Health Organization (WHO) toxicity criteria.
RESULTS
Of all 40 patients (32 men, 8 women; age range 37 to 73 years; median 63 years), 3S patients were assessable for response. 15 patients had stage IIIb disease and 25 had stage IV. Nineteen patients were histologically classified as adenocarcinoma (47.5%), 17 as squamous cell carcinoma (42.5%), 1 as large cell carcinoma (2.5%), 1 as mixed carcinoma (2.5%) and 2 as undifferentiated carcinoma (5.0%). The overall response rate was 20%. None of the patients showed complete response while 7 showed partial response (20%), 5 had stable diseases (23%) and 23 had progressive diseases (57%). During a total of 119 courses, hematologic toxicity was negligible. Granulo- cytopenia worse than WHO grade 3 occured in 11.8%, anemia in O.S% and thrombocytopenia in 0.8%, respectively. Non-hematologic toxicity was minor and easily controlled. There was no case of febrile neutropenia or treatment-related death.
CONCLUSION
The single agent efficacy of gemcitabine is comparable to other agents commonly used to treat NSCLC. Gemcitabine has unusually mild side effect profile for such an active agent. This significant activity in conjunction with a very favorable toxicity profile supports further investigation in combination with other agents in patients with inoperable NSCLC.
