摘要
目的本次研究主要比较伊立替康联合顺铂方案(IP)与依托泊苷联合顺铂方案一线治疗小细胞肺癌的近期疗效和不良反应。方法61例符合入组条件的SCLC患者采用随机方法分为IP组和EP组,Ⅲ期38例(62.3%),Ⅳ期23例(37.7%)。IP组方案:伊立替康80mg/m2,第1、8天,顺铂25mg/m2,第1~3天,21d为1个周期;EP纽方案:依托泊苷100mg/m2,第l~3天,顺铂25mg/m2,第1~3天,21d为1周期。共4个周期,2个周期后评价为未获缓解的患者交换分组继续研究。结果所有患者均完成预定的4周期化疗和疗效评价,客观有效率(ORR)为82.0%(50/61),IP组ORR为74.2%,EP组ORR为66.7%(x2=0.415,P=0.582),其中IP组完全缓解16例(51.6%),EP组完全缓解8例(26.7%)(x2=5.056,P=0.033)。交换组共18例患者,部分缓解7例(38.9%),IP+EP8例中部分缓解2例(25%),低于EP+IP10例中部分缓解5例(50%)(X2=1.169,9=0.367)。本研究无化疗相关死亡病例。IP组主要不良反应包括粒细胞减少75.6%、腹泻46.3%和呕吐41.5%。EP组主要不良反应包括呕吐71.1%、粒细胞减少68.4%和贫血28.9%。其中,IP组腹泻发生率与EP组比较差异有统计学意义(P〈0.01)。G3以上不良反应发生率比较差异均无统计学意义(19〉0.05)。结论IP方案化疗具有更高的完全缓解率,腹泻发生率也明显高于EP方案,通过积极对症处理,可以耐受。
Objective The purpose of this randomized trial is to compare the efficacy and toxicity of irinoteean plus eisplatin(IP) with EP as the first-line chemotherapy. Methods A total of 61 patients with SCLC were randomly divided into arm IP( irinotecan 80 mg/m2, dl,8 ;eisplatin 25 mg/m2, dl -3,21 d/cycle) and arm EP( etoposide 100 mg/m2 ,eisplatin 25 mg/m2 ,dl -3,21 d/cycle). 38 patients(62.3% ) were staged HI according to 7th UICC TNM staging, 23 were staged IV. All patients completed 4 cycles chemotherapy, 18 patients altered regimen while no response was found after 2 cycles. Results The total objective response rate(ORR) was 82.0%, 74.2% (IP)vs. 66.7% (EP) (P = 0. 582), the rate complete response(CR) with IP and EP was 51.6% and 26.7% ,respectively (P = 0. 033). 7 patients(38.9% ) experienced partial response after altered regimen, there was no difference between IP and EP(2/8 vs 5/10, P = 0. 367). The common adverse effects included nentropenia (75.6%), diarrhea (46.3%), and vomiting (41.5%) of IP, vomiting(71.1% ), neutropenia (68.4%) and anemia(28.9% ) of EP, the morbidity of diarrhea was higher of IP than EP(46.3% vs. 10. 5% , P 〈 0. 01). Conclusions IP regimen cause a higher rate of CR than EP for SCLC, a higher morbidity of diarrhea too, the adverse effects can be tolerated by appropriate treatment.
