ABSTRACT
<p><b>OBJECTIVE</b>The aim of this study is to evaluate the efficacy and safety of Gefitinib in the treatment of Chinese patients with recurrent advanced non-small-cell lung cancer (NSCLC).</p><p><b>METHODS</b>120 patients were enrolled in this trial from September 2002 to March 2005, and 103 patients were evaluable. All patients were histologically or/and cytologically confirmed to have a locally advanced or metastatic NSCLC, and failed to previous standard treatments. The patients received orally 250 mg of Gefitinib once daily until the disease progression or intolerance to toxicity. First evaluation of response was undertaken one month after drug initiation, then every 2 or 3 months till disease progression. Each patient was followed up every 6 months untill death or end of follow-up.</p><p><b>RESULTS</b>Among the 103 evaluable patients, the objective response rate was 18.4% (19/103), and the disease control rate was 51.5% (53/103). The median time to progression (mTTP) was 3 months (range 0.2 approximately 40), the median survival time (MST) was 9.8 months (range 0.5 approximately 51), the 1-, 2-, 3-year survival rates were 44.7%, 26.4% and 13.2%, respectively. The TTP of 41 patients was longer than 6 months with a MST of 25.5 months. The results of COX model analysis suggested that the patients with adenocarcinoma, rash and favourable performance status (PS) had longer TTP. The patients with favourable PS and well controlled disease had longer survival time. Adverse events included skin rash, dry skin, diarrhea and elevation of serum glutamate pyruvate transaminase (SGPT), and were usually mild.</p><p><b>CONCLUSION</b>Gefitinib is effective in treatment of patient with recurrent advanced NSCLC. The patients with controlled disease may achieve a long survival, and the adverse reactions are mild and tolerable.</p>
