There are little data on the efficacy and safety of taxane/platinum with definitive radiotherapy (RT) for esophageal/GEJ cancer. This article is a retrospective analysis of patients who received weekly paclitaxel 50 mg/m(2) and carboplatin AUC 2 with radical definitive RT for locally advanced esophageal/GEJ cancer. Between February 2011 and July 2014, 179 patients were included. The median age was 54 years. Ninety-two percent of patients had squamous histology. Mean RT dose was 58.7 Gy in 32 fractions over 53 days, with mean of six chemotherapy cycles. Fifty-six percent of patients developed ≥grade 3 acute toxicities, commonly febrile neutropenia (12%) and infection (11%); ≥grade 3 laboratory abnormalities included hyponatremia (38%), leukopenia (49%), neutropenia (27%), and anemia (16%). Twelve percent of patients developed ≥grade 3 chronic toxicity. Fatal toxicities included six during CRT, eight within 30 days of completing CRT, and three chronic. Radiologic response was 49% (CR 5.6%, PR 43%). Follow-up endoscopy showed remission in 53% and residual disease in 14%. At a median follow-up of 28 months, median PFS was 11 months (95% CI: 8-13.9), median OS was 19 months (95% CI: 15.4-22.6), and estimated 1-year, 2-year, and 3-year survivals were 70%, 47%, and 39%, respectively. Weekly paclitaxel-carboplatin concurrently with definitive RT is efficacious with manageable toxicity.

关于紫杉烷/铂类联合根治性放疗(RT)治疗食管/胃食管交界部癌的疗效和安全性的数据较少。本文是一项对接受每周50mg/m²紫杉醇和AUC 2卡铂联合根治性RT治疗局部晚期食管/胃食管交界部癌患者的回顾性分析。2011年2月至2014年7月期间,纳入了179例患者。中位年龄为54岁。92%的患者为鳞状组织学类型。平均放疗剂量为58.7Gy,分32次在53天内完成,平均化疗周期数为6个。56%的患者发生≥3级急性毒性反应,常见的有发热性中性粒细胞减少(12%)和感染(11%);≥3级实验室异常包括低钠血症(38%)、白细胞减少(49%)、中性粒细胞减少(27%)和贫血(16%)。12%的患者发生≥3级慢性毒性反应。致命毒性反应包括同步放化疗期间6例、完成同步放化疗后30天内8例和慢性期3例。放射学缓解率为49%(完全缓解5.6%,部分缓解43%)。随访内镜检查显示缓解率为53%,残留病灶率为14%。中位随访28个月时,中位无进展生存期为11个月(95%CI:8 - 13.9),中位总生存期为19个月(95%CI:15.4 - 22.6),估计1年、2年和3年生存率分别为70%、47%和39%。每周紫杉醇 - 卡铂同步联合根治性放疗有效且毒性可控。[该试验已在印度临床试验注册中心(CTRI)注册,注册号:CTRI/2014/07/004776。]
