ABSTRACT

<p><b>BACKGROUND</b>Chemotherapy is the main treatment measure of advanced non-small cell lung cancer(NSCLC).The aim of this study is to explore the efficacy,toxicity,time to disease progression(TTP) and overall survival under the combined chemotherapy with gemcitabine(GEM) plus cisplatin(DDP) in the treatment of advanced NSCLC.</p><p><b>METHODS</b>Retrospective review was conducted on 79 chemotherapy-naive cases of advanced NSCLC treated with GEM and DDP from October 1999 to November 2005.Among 79 patients,51 were male and 28 female;the median age was 53 years old(ranged from 21 to 74);there were 17 cases of squamous cell carcinoma,53 cases of adenocarcinoma,3 cases of large cell carcinoma,1 case of adeno-sqamous cell carcinoma,5 unidentified cases;there were 26 cases in IIIB stage and 53 cases in IV stage according to AJCC 1997 standard.All patients received GEM 800-1250 mg/m² on days 1 and 8 and DDP 75-80 mg/m² on day 1 or 30 mg/m² for three days by intravenous administration,with 21 days as one cycle.Each patient received 2-4 cycles chemotherapy.</p><p><b>RESULTS</b>The total clinical reponse rate(complete and partial response) was 31.6%,and clinical benefit rate(complete and partial response and stable disease) was 73.4%.1-year survival rate was 64.9%,2-year survival rate was 32%.After median follow-up of 2.33 years,median TTP was 5.06 months.The main toxicities were nausea,vomitting and hematological toxicities.The rates of grade III to IV leukopenia and thrombocytopenia were 25.4% and 31.6% respectively.Other toxicities were slight and tolerable.</p><p><b>CONCLUSIONS</b>Combined chemotherapy with GEM plus DDP as first-line treatment to advanced NSCLC is an effective and feasible regimen,which is one of the standard regimens.For old patients,this regimen is a good choice.The fit dosage of GEM for Chinese is 1000 mg/m².</p>
