Abstract:
OBJECTIVETo evaluate the efficacy and safety of gefitinib for the treatment of advanced non-small cell lung cancer (NSCLC).
METHODS125 patients with advanced NSCLC who had failed or not tolerated or refused chemotherapy received 250 mg oral doses of gefitinib once daily until the disease progression or intolerable toxicity.
RESULTSA total of 125 NSCLC patients were studied, the overall response rate (RR) and the disease control rate (DCR) after administration of gefitinib were 35.2% (44/125) and 77.6% (97/125), respectively. The median progression-free survival and the median survival time were 5.8 and 11.2 months, respectively. The one-year survival rate was 40.5%. The response rate was significantly higher in females, adenocarcinoma and nonsmokers than that in males, non-adenocarcinoma and smokers (P < 0.05). The response rate did not show significant differences regarding ECOG score or previous treatment. The median progression-free survival was significantly longer in ECOG PS 0-1 and gefitinib effective patients than that in ECOG PS >or= 2 and gefitinib ineffective patients (P < 0.01). The median survival time was significantly longer in adenocarcinoma, nonsmokers and gefitinib effective patients than that in non-adenocarcinoma, smokers and gefitinib ineffective patients (P < 0.05). The most common side effects were rash (51.2%) and diarrhea (34.4%), but usually were mild.
CONCLUSIONGefitinib is effective and safe in the treatment of advanced NSCLC patients.
