A clinical comparative study of GP and TP 1st-line chemotherapies for advanced non-small cell lung cancer

Objective： The aim of the study was to evaluate the efficacies of initial gemcitabine plus cisplatin （GP） and paclitaxel plus cisplatin （TP） 1st-line chemotherapies for advanced non-small cell lung cancer （NSCLC） and observe their side effects. Methods： Eighty-one cases were randomly divided into two groups： GP group and TP group. In GP group, adminis- tered gemcitabine （GEM） 1000 mg/m2 on days 1 and 8; i.v. cisplatin （DDP） 30 mg/m2 from days 2 to 4 on a 28-day cycle. In TP group, administered paclitaxel （PTX） 175 mg/m2 on day 1, i.v. DDP 30 mg/m2 from days 2 to 4 on a 28-day cycle. Results： GP group had an overall response rate （ORR; CR＋PR） of 45.0% （18/40）. TP had an overall response rate of 43.2% （16/37）. Short-term ORR had no significant difference between two groups （x2 = 0.527, P = 0.957）. GP had median survival time of 11 months and 37.7% of one-year survival rate, while TP showed 11 months of median survival time and 31.7% of one-year survival rate. Survival had no significant difference between two groups （x2 = 0.140, P = 0.708）. However, main side effects varied. Thrombocytopenia of GP group was significantly more than that of TP group, while peripheral neuritis, nausea/vomiting and myalgia of TP group were significantly more than those of GP group. Conclusion： Both GP and TP regimens had no significant difference in short-term treatment effect and survival rate for initial treatment of advanced NSCLC. However, side effects related to GP regimen treatment were slighter. Therefore, it was considered as the preferred initial first-line treatment for NSCLC.

Comparison of two different kinds of regimens in treatment of advanced non-small cell lung cancer

Objective： The aim of this study was to analyze and compare the recent efficacy and toxicity of a three-drug platinum-based regimen （A regimen）： [cisplatin （DDP） ＋ gemcitabine （GEM） ＋ vinorelbine （NVB）] and a two-drug combination without a platinum drug （B regimen）： GEM ＋ NVB, which were used to treat 55 advanced non-small cell lung cancer （NSCLC） patients, in a bid to provide a guidance for clinical treatment. Methods： Twenty-four cases of advanced NSCLC （stage Ill-IV） patients were treated with A regimen （DDP 35 mg/m^2 d1-3; GEM 1250 mg/m^2 d1, 8 ）. The other 31 cases were treated with B （GEM 1250 mg/m^2 d1,8; NVB 25 mg/m^2 d1, 8 ）. Repeat every 3 weeks for 6 courses. Results： In A regimen group, the overall response rate was 45.8% （CR ＋ PR = 11）, median response time was 5.5 months, median survival time was 11 months and 1-year survival rate was 41.7%. In B regimen group, the overall response rate was 48.4% （CR ＋ PR = 15） and median response time, survival time and 1-year survival rate were respectively 6.5 and 10 months and 41.9%. The major toxicities were nausea/vomiting, myelosuppression in A regimen group, myelosuppression and phlebitis in B regimen group, respectively. Conclusion： A regimen and B regimen for advanced NSCLC have similar response rate （P 〉 0.05）. B regimen, a two-drug combination without a platinum drug is of less toxicity and more safety than A regimen, a three-drug platinum-based regimen and is recommended to be a regimen in the first-line treatment for advanced NSCLC.

紫杉醇或健择联合奥沙利铂治疗非小细胞肺癌的临床对照研究

目的比较健择联合奥沙利铂方案与紫杉醇联合奥沙利铂方案治疗非小细胞肺癌(NSCLC)的疗效及毒副反应。方法选择2003年1月～2009年11月于我院呼吸内科进行化疗的160例Ⅲ～Ⅳ期NSCLC患者,分为健择组及紫杉醇组,两组各80例。紫杉醇组用紫杉醇联合奥沙利铂化疗,健择组用健择醇联合奥沙利铂化疗。结果健择组与紫杉醇组的短期疗效分别为61.3%和45.0%,差异有显著性(P<0.05),同时健择组毒副反应发生率较紫杉醇组低。结论健择联合奥沙利铂治疗NSCLC有效率较紫杉醇联合奥沙利铂有效率高,二者之间有显著性差异,且健择联合奥沙利铂方案的毒副作用较少,而且较轻微,故健择联合奥沙利铂方案是治疗NSCLC的较好选择。
