Abstract/OtherAbstract:
Treatment of elderly or poor performance status (PS) patients with advanced non-small-cell lung cancer (NSCLC) is a debated topic. To evaluate the efficacy of a modified schedule of gemcitabine, 59 patients unfit for platinum were enrolled. Mean age was 75.8 years and 41 % of patients had an ECOG PS 2. Gemcitabine was given at 1000 mg/m(2) on days 1, 8 each 28. Most of patients received gemcitabine as first-line chemotherapy, which was continued as maintenance over 6 cycles in responding and stable patients. Median overall survival (OS) and progression-free survival (PFS) were 7.2 and 5 months. In those 45 evaluable patients, treatment resulted in 1 complete remission (CR), 9 partial remissions (PR), and 20 stable diseases (SDs) with a response rate (CR + PR) of 22 % and a clinical benefit (CR + PR + SD) of 68 %. Gemcitabine was continued over 6 cycles in 16 patients (27 %). These patients were treated until progression with a mean of further 8.6 cycles. Median OS and PFS in these selected patients were 19 and 16 months. The toxicity profile was excellent with only 8 % of overall G3-G4 adverse events. None of the 16 patients under the maintenance phase reported significant toxicity. Gemcitabine given at a lower dose intensity than standard should be considered as valuable therapeutic option in elderly or poor PS patients with advanced NSCLC unfit for platinum. Extending the treatment beyond 6 cycles in responding patients is feasible and may prolong survival.
