Abstract:
Objective:To make a prospective study on the effectiveness and safety of toremifene (TOR) combined with novelbine/cisplatin (NP) in the treatment of patients with advanced non-small cell lung cancer (NSCLC) whose first line platinum-based chemotherapy was failure. Methods:Forty-four patients with stage ⅡB-Ⅳ NSCLC, who failed in the first line cisplatin-based chemotherapy from January 2004 to February 2006, were enrolled in this study. All the patients received TOR combined with NP second line chemotherapy for two cycles. The response rate and adverse reaction were evaluated. The survival rate was analyzed.Results:The 44 patients received average 1.8 cycles of chemotherapy (1-3 cycles). The response of 37 patients could be evaluated including 21 patients who received NP regimen before and 16 patients who received platinum-based chemotherapy. After second line therapy, 4 of the 37 patients had partial response (PR), 19 had stable disease (SD), 14 had progressive disease (PD), and no patient had complete response (CR). The total response rate (CR+PR) was 10.8% (4/37). The disease-controlling rate (CR+PR+SD) was 62.2% (23/37). The response rate and disease-controlling rate of squamous cell lung cancer (SCC) were 27.3% (3/12) and 72.7% (8/12), which were significantly higher than adenocarcinoma [0% (0/18) and 44.4% (8/18), P<0.05]. The median survival time was 8.2 months, the median time for SD was 4.0 months (1.0-10.2 months), and the 1-year survival rate was 24.4%. The median survival time and 1-year survival rate of SCC patients had no significant difference compared with adenocarcinoma patients (9.2 vs 7.1 months; 33.3% vs 27.7%, P＝0.72). There was no significant difference in survival rate between male and female patients. One patient stopped therapy for liver function injury (hyperbilirubinemia). The adverse reactions induced by chemotherapy mainly included gastrointestinal reaction, bone marrow suppression, and liver function injury. No serious adverse reaction occurred. Conclusion:The clinical efficacy of second line TOR combined with NP regimen is similar with the first line regimen for NSCLC patients, especially for SCC patients. The frequency of adverse reaction is not increased.
