食管癌术后复发转移的类型及预后分析

目的探讨食管癌术后复发转移的类型及影响生存的预后因素。方法对食管胸段鳞癌根治术后复发转移的１８５例进行回顾性分析。结果复发转移的中位生存时间为３０３天。复发转移类型：淋巴性转移１３７例,血行性转移１１例,混合型转移２９例,吻合口复发８例。本组半年及１,２,３,４年生存率分别为７０．０％、４７．１％、１９．８％、１２．２％和０％。多因素分析显示：肿瘤浸润深度、淋巴结转移、手术方式及不同治疗方案是影响生存率的预后因素。结论肿瘤浸润深度和淋巴结转移反映了肿瘤的生物学行为。提倡颈部吻合术,颈清扫术仅限于少数患者。放疗＋化疗可能延长复发转移患者的生存期,较有效的化疗方案有待进一步研究。

Recurrence pattern and prognosis of esophageal cancer following tumor resection

Objective To determine the recurrence patterns and prognosis after resection of esophageal cancer. Methods One hundred eighty five patients who devoloped recurrence after curative resection for squamous cell carcinoma of the thoracic esophagus were analyzed retrospectively. Results The median recurrence time was 303 days. Recurrence pattern was catagorized into lymphatic, hematogenous, mixed and anastomotic. The number of patients in each recurrence group was 137, 11,29, and 8, respectively. The 0.5 , 1 , 2 , 3-, and 4 year overall survival rate was 70.7%, 47.1%, 19.8%, 12.2% and 0%, respectively. Multivariate analysis showed that depth of tumor invasion, lymph node metastasis, operative procedure and different regimens of therapy were significant prognostic factors. Conclusion Lymph node metastasis and the depth of invasion may reflect the biologic behavior of the tumor. Esophagectomy with cervical anastomasis is recommended, additional cervical lymphadenectomy is beneficial in a few patients. Radiotherapy combined with chemotherapy may prolong survival time of patients with recurrence.
