摘要
目的探讨西妥昔单抗联合替吉奥治疗老年转移性结直肠癌的疗效及安全性。方法收集一线解救化学治疗(化疗)不能耐受及拒绝一线化疗方案的32例老年患者的临床资料。按K-Ras基因表型分为联合用药组(16例),对照组(16例)。联合用药组患者采用西妥昔单抗联合替吉奥方案治疗,西妥昔单抗首次剂量为400mg/m^2,以后每周剂量为250mg/m^2,每周1次。替吉奥根据体表面积来确定初始剂量,体表面积〈1.25m^2,40mg;体表面积1.25-1.5m^2,50mg;体表面积〉1.5m^2,60mg。用法:2次/d,早饭后和晚饭后分别口服1次,连续服用14d,停药7d,3周为1个周期;对照组根据体表面积服用相应剂量的西妥昔单抗。至少给予2个周期治疗。观察疗效及不良反应。结果联合用药组完全缓解3例(18.75%),部分缓解4例(25.00%),病情稳定5例(31.25%),病情进展4例(25.00%),有效率43.75%(7/16),疾病控制率75.00%(12/16)。对照组完全缓解3例(18.75%),部分缓解3例(18.75%),病情稳定3例(18.75%),病情进展7例(43.75%),有效率37.50%(6/16),疾病控制率56.25%(9/16)。联合用药组的疾病控制率均优于对照组,差异均有统计学意义(P〈0.05);2组有效率比较,差异无统计学意义(P〉0.05)。联合用药组和对照组常见的不良反应为色素沉着、皮疹,其发生率分别为87.50%(14/16)和56.25%(9/16),恶心呕吐的发生率分别为62.50%(10/16)和56.25%(9/16)。2组不良反应发生率差异无统计学意义(P〉0.05)。结论西妥昔单抗联合替吉奥治疗老年转移性结直肠癌较对照组更有效,不良反应可耐受。
Objective To study the efficacy and safety of cetuximab plus S1 in treatment of aged patients with metastatic colorectal cancer. Methods Clinical data of 32 patients with metastatic colorectal cancer were col- lected. The patients could not tolerate first-fine chemotherapy or refused first-line chemotherapy. According to the status of K-Ras, the patients were divided into two groups. Of the 32 patients, 16 patients were treated with cetux- imab plus S1 (Combination regimen) ,16 patients were treated with S1 singly (Single agent regimen). All patients who received 2 or more cycles could be evaluated. Results The response rate (RR) of combination regimen and single agent regimen were 43.75% vs 37.50% (P 〉 0.05) ;disease control rate (DCR) 75.00% vs 56.25% (P 〈 0.05 ); there was no significant difference on side-effects between the two regimens (P 〉 0.05 ). Conclusions Cetuximab plus S1 has an optimal efficacy in patients with metastatic colorectal cancer. The toxicity is well- tolerated.
