Abstract:
Objective To compare the efficacy of trimodality therapy and chemoradiation therapy (CRT) alone in patients with locally advanced resectable esophageal squamous cell carcinoma (SCC).Methods A total of 124 cases with locally advanced resectable esophageal SCC were retrospectively analyzed and classified into 2 groups.Fifty-four cases in trimodality group were treated with surgery and preoperative chemoradiation,while 70 cases in CRT alone group only received radiation and chemotherapy.Local tumor control,3-year survival and treatment-related mortality were assessed.Results The local recurrent rate of the resected patients was 18.5％ in trimodality group and 35.7％ in CRT alone group,respectively(x2 =4.445,P ＜ 0.05).The 3-year progression-free survival (PFS) was 65.3％ (95％ CI 50.7-80.5) in trimodality group and31.9％ (95％CI 19.6-44.2) in CRT alone group (P＜0.05),while the overall survival (OS) 66.3％ (95％ CI43.0-89.6) and 34.4％ (95％ CI 21.1-47.7),respectively(P ＜ 0.05).Treatment-related mortality was 1.9％ in trimodality group and 2.9％ in CRT alone group (P ＞ 0.05).For CRT alone group,the sub-group analysis showed that there was no statistically significant difference in the 3-year OS between patients who received 50-50.4 Gy and those who received the dose over 50.4 Gy (39.9％ 95％ CI 18.5-61.3 vs.31.5％ 95％ CI 14.8-48.2,P ＞0.05).Conclusions Compared with CRT alone,trimodality therapy showed the superior local control,PFS and OS,with similar treatment-related mortality in the treatment of patients with SCC of esophagus.The role of surgery could not be replaced by CRT alone even with the augment of radiation dose.
