摘要
目的探讨和比较同期减量放化疗与序贯放化疗治疗不能手术的Ⅲ期NSCLC的毒副反应和近期疗效。方法病理证实为Ⅲa,Ⅲb期(非恶性胸腔积液)不能手术的初治NSCLC患者80例随机分为2组。同期放化疗组(A):2周期紫杉醇(减半量)+顺铂(11P)方案化疗,于放疗第一天同期进行。放疗用三维适形放疗,放疗至总量60Gy-70Gy。同期放化疗结束后继续Te(全量)方案巩固化疗3周期。序贯放化疗组(B):入组后先行放疗,放疗方案同A组,放疗结束后行Te(全量)方案化疗4—5周期。采用WHO近期疗效评价标准和放化疗毒副反应分级标准进行评定。结果A组近期有效率为80.0%,B组为57.5%(x^2=4.71,P〈0.05),A组Ⅲ,Ⅳ度急性放射性食管炎,白细胞减少,恶心呕吐和皮肤反应发生率分别为47.5%,42.5%,52.5%和57.5%明显高于B组的25.0%,17.5%,30.0%和17.5%(P〈0.05);A,B组Ⅲ,Ⅳ度急性放射性肺炎,脱发发生率分别为32.5%,7.5%和20.0%,27.5%(P〉0.05)。结论TP方案减量同期放化疗治疗不能手术的Ⅲ期NSCLC,近期疗效较序贯放化疗组高,副反应经积极对症治疗可以耐受。
Objective Evaluate the early response and toxicity of concurrent chemoradiotherapy. Methods Eighty unresectable stage Ⅲa- Ⅲb NSCLC patients pathologically proved were randomly divided into 2 groups. Group A : patients were treated with concurrent chemotherapy of paclitaxe[ ( 100 mg/m^2, on day2. ) and cisplatin (30 mg/m^2, on days 2 -6 ) (TP regimen)plus 3 - dimensional conformal radiotherapy. The total dose was 60 Gy -70 Gy. After the radiation,3 cycles of TP regimen were performed,but the dose of paclitaxel was 200 mg/ m^2. Group B: patients received sequential chemoradiotherapy. First radiation was performed as same as group A. Then chemotherapy of TP( paclitaxel 200 mg/m^2, on day 2, DDP 30 mg/m^2, on days 2 -6)was followed for 4 -5 cycles. Results The overall response rate in concurrent and sequential groups was 80.0% and 57.5% respectively ( x^2 = 4.71, P 〈 0.05 ). Incidences of grade Ⅲ- Ⅳ acute radiation esophagitis, leukopenia, nausea/vomiting and skin reaction were 47.5% ,42.5% ,52.5% and 57.5% in group A,and 25.0% ,17.5% ,30.0% and 17.5% in group B respectively(P 〈 0.05 ). Incidences of grade Ⅲ- Ⅳ acute radiation pneumonitis and lose hair rate was 32.5% ,7.5 % in group A and 20.0% ,27.5% in group B respectively ( P 〉 0. 1 ). Conclusion Concurrent chemoradiotherapy is weU tolerated in most unresectable stage Ⅲa- Ⅲb NSCLC patients. Its early response is better than sequential chemoradiotherapy.
