Phase II clinical trial on gemcitabine in the treatment of stage IIIB-IV non-small cell lung cancer / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of domestic Gemcitabine in the treatment of patients with stage IIIB approximately IV non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>124 NSCLC patients were randomized into three groups: Group A: single drug group, 40 cases, gemcitabine 1 000 mg/m(2) + NS 100 ml or 200 ml was infused within 30 approximately 60 minutes on D1, 8 and 15, with 28 days taken as one cycle. Group B: combined treatment group, 36 cases, in addition to the above protocol, cisplatin 30 mg/m(2) was infused within 60 approximately 120 min, on D1, 2 and 3. Group C: combined control group: 39 cases, the protocol applied was the same as group B except domestic gemcitabine being replaced by imported gemzar. The efficacy and side effects of treatment were evaluated after 8 weeks of treatment.</p><p><b>RESULTS</b>115 patients could be evaluated for response rate. PR was observed in 9/40 (22.5%) of group A, 15/36 (41.6%) in group B and 15/39 (38.36%) in group C. There was no significant difference of PR rates between group B and group C (P = 0.552). 117 patients who received the second cycle of treatment were evaluated for toxicity. The incidence of grade III approximately IV nausea, vomiting and loss of appetite was much higher in group B. Hematological toxicity of groups B and C was higher than that of group A. There was no significant difference between groups B and C.</p><p><b>CONCLUSION</b>The efficacy and incidence of side effects between domestic gemcitabine and the imported gemzar are similar.</p>
