From 1976 until 1990 a total of 212 patients with squamous cell carcinoma of the thoracic esophagus were referred for surgical treatment. Resectability was 84.1% (161 of 191). Actuarial 5-year survival in patients with negative lymph nodes was 51.2% versus 12.4% in lymph node-positive patients. Therefore advanced carcinoma was defined to compromise all patients with involved regional (N1) or distal lymph nodes (M+Ly) as well as patients with T4 tumors or solid organ metastasis (M+org) irrespective of their lymph node status. Comparing complete (R0) versus incomplete (R1-R2) resections for stage III and IV carcinoma revealed 20% and 0% five-year survivals, respectively. There was no 5-year survival in the stage IV group. When excluding solid organ metastasis, the median survival shifted from 8.5 months after incomplete (R1-R2) to 20 months after complete (R0) resection. In 1991 three-field lymphadenectomy was initiated that included bilateral cervical lymphadenectomy. Thirty-seven patients have been treated so far (23 squamous cell carcinoma, 14 adenocarcinomas). Cervical lymph nodes were positive in 24.3% with an incidence up to 28.5% for distal-third carcinoma. Subsequently, 6 patients (16%) moved from M0 to M+Ly status. Our results confirm the key role of surgery not only in improving survival and locoregional tumor control but in refining the accuracy of staging advanced carcinomas provided complete resection is possible.(ABSTRACT TRUNCATED AT 250 WORDS)
从1976年至1990年,共有212例胸段食管癌鳞状细胞癌患者被转诊接受手术治疗。可切除率为84.1%(191例中的161例)。淋巴结阴性患者的5年精算生存率为51.2%,而淋巴结阳性患者为12.4%。因此,晚期癌被定义为包括所有区域淋巴结受累(N1)或远处淋巴结转移(M+Ly)的患者,以及T4肿瘤或实体器官转移(M+org)的患者,无论其淋巴结状态如何。比较III期和IV期癌的根治性(R0)与非根治性(R1-R2)切除,发现5年生存率分别为20%和0%。IV期组无5年生存率。排除实体器官转移后,中位生存期从不完全切除(R1-R2)后的8.5个月转变为根治性切除(R0)后的20个月。1991年开始实施包括双侧颈淋巴结清扫的三野淋巴结清扫术。迄今为止,已治疗37例患者(23例鳞状细胞癌,14例腺癌)。颈淋巴结阳性率为24.3%,远端三分之一癌的发生率高达28.5%。随后,6例患者(16%)从M0转变为M+Ly状态。我们的结果证实了手术的关键作用,不仅在于提高生存率和局部区域肿瘤控制,还在于提高晚期癌分期的准确性,前提是有可能进行根治性切除。(摘要截断于250字)
