局部晚期食管鳞状细胞癌术后放疗和化疗的前瞻性研究

目的 评价局部晚期食管鳞状细胞癌(FSCC)手术后放射治疗和化疗的疗效.方法 将1997年1月至2004年6月间入院的158例ESCC(Ⅱ-Ⅲ期)患者随机分为术后放化疗组(78例)和单纯手术组(80例).后经微调和排查,实际术后放化疗组为74例,单纯手术组为77例.对比两组患者的并发症发生率、局部复发率和远处转移率、生存率及无进展生存率.结果 患者平均随访45个月,术后放化疗组的并发症发生率与单纯手术组比较,差异无统计学意义(P>0.05).术后放化疗组局部复发和远处转移率低于单纯手术组(P<0.05).术后放化疗组的中位生存时间(53.5个月)与单纯手术组(37个月)比较,差异有统计学意义(P<0.05),两组的1年生存率比较,差异无统计学意义(P>0.05),但3、5和10年生存率比较,术后放化疗组优于单纯手术组(P<0.05).术后放化疗组的中位无进展生存期(46个月)与单纯手术组(34个月)比较,差异有统计学意义(P<0.05),两组1年无进展生存率比较,差异无统计学意义(P>0.05),但3、5和10年无进展生存率比较,术后放化疗组优于单纯手术组(P<0.05).结论 术后合理应用放化疗可有效提高局部晚期ESCC患者的无进展生存时间及长期生存率.

A prospective comparison between surgery alone and postoperative chemoradiotherapy for locally advanced esophageal squamous cell carcinoma

Objective To investigate the role of postoperative chemoradiotherapy ( CRT) as a multimodality treatment option for locally advanced thoracic esophageal squamous cell carcinoma (ESCC) by a prospective comparison between surgery alone and postoperative CRT. Methods Using preoperative computed tomography (CT)-based staging criteria, 158 patients with ESCC (stage Ⅱ-Ⅲ) were enrolled in this prospective study. With informed consent, the patients were randomized into two groups: postoperative CRT (78 cases ) and surgery alone (S, 80 cases). After a few minor adjustments to the enrolled patients, the actual patients of postoperative CRT group and S group were 74 cases and 77 cases, respectively. Comparison of the complications, local recurrence rate, distant metastasis rate, survival rate and progression-free survival in the two groups was carried out. Results With a median follow-up of 37.5 months, the 1-,3-,5-, 10-year overall survival (OS) rates were 91.0% , 62.8%,42.3%,24.4% and 87.5% , 51.3% , 33.8% , 12. 5% for the postoperative CRT and S arm, respectively. A significant difference in OS was detected between the two arms (P =0.0276). There was a significant difference of progression-free survival (PFS) between the two arms (P=0.0136). The local recurrence rates in the postoperative CRT group and S group were 14.9% and 36.4% , respectively (P<0.05). No significant difference was detected between the complications of the two groups ( P > 0. 05). Toxicities of chemoradiotherapy in the postoperative CRT arm were moderate, which can be relieved rapidly by adequate therapy. Conclusion Rational application of postoperative chemoradiotherapy can provide a benefit in progression-free survival and overall survival in patients with locally advanced esophageal squamous cell carcinoma.
