摘  要: 目的研究病理检查无淋巴结转移(pN0)的pT1b^T4a期胸段食管鳞癌患者术后复发转移的临床相关高危因素。方法回顾性收集2004年1月至2012年12月上海市胸科医院食管疾病诊疗中心数据库中行根治性切除术的胸段食管鳞癌患者的临床及随访资料。病例入组标准为:(1)首次发病、无淋巴结转移和远处转移;(2)肿瘤分期均为pT1bN0M0~pT4aN0M0;(3)采用经右胸翻身二切口或三切口食管癌根治性手术(R0),均行二野或三野淋巴结清扫;(4)手术前后未进行抗肿瘤治疗;(5)随访资料完整。研究这组患者术后复发转移情况,并用Logistic回归分析方法分析复发转移相关的临床病理学因素。结果符合入组标准的患者有112例,其中男94例,女18例;年龄(58.6 ± 7.7)岁;食管鳞癌位于胸上段25例,胸中段67例,胸下段20例;高分化鳞癌12例,中分化鳞癌49例,低分化鳞癌48例;Ⅰa期4例,Ⅰb期9例,Ⅱa期24例,Ⅱb期62例,Ⅲa期13例;肿瘤长度〉 4 cm 43例,≤4 cm 69例。术后复发转移43例(38.4%),其中局部区域性复发24例(21.4%),远处转移13例(11.6%),局部区域性复发合并远处转移6例(5.4%)。Logistic多因素分析发现,肿瘤细胞低分化(OR= 1.899,95%CI:1.233~2.925,P= 0.004)、肿瘤位于食管上中段(OR= 2.351,95%CI:1.188~4.653,P= 0.014)、肿瘤长度〉4 cm(OR= 2.381,95%CI:1.009~5.618,P= 0.048)为鳞癌pT1b^T4aN0M0期患者术后总体复发转移的独立危险因素。进一步分层分析发现:低分化(OR= 1.730,95%CI:1.121~ 2.671,P= 0.013)是术后局部区域性复发的独立危险因素;Ⅱb~Ⅲa期肿瘤是术后远处转移的独立危险因素(OR= 3.372,95%CI:1.206~9.428,P= 0.021)。结论肿瘤细胞低分化、肿瘤位于食管上中段和肿瘤长度〉4 cm的pN0期胸段食管鳞癌患者,术后易出现复发转移,其中肿瘤细胞低分化 ObjectiveTo investigate the associated high risk factors of postoperative relapse and metastasis for patients with confined tumors (grade pT1b-4a) without lymph-node metastases (pN0) in thoracic esophageal squamous cell carcinoma (ESCC) .MethodsClinicopathological and follow up data of ESCC patients undergoing radical surgical resection as primary treatment in the Department of Thoracic Surgery, Shanghai Chest Hospital between January 2004 and December 2012 from Hospital Database were retrospectively collected. The inclusion criteria were as follows: (1) the first development of ESCC confirmed by histopathology without lymphatic and distant metastasis; (2) pathological stage of pT1bN0M0 to pT4aN0M0 according to the Union for International Cancer Control (UICC) in 2009; (3) curative trans-thoracic esophagectomy with R0 (tumor-free surgical margin) resection, using the Ivor-Lewis or McKeown procedure; two-field lymphadenectomy or three-field lymph node dissection based on the positive results of preoperative cervical ultrasonography examination or CT scan; (4) without adjuvant chemotherapy and/or radiotherapy before and after operation; (5) complete follow-up data. Logistic regression analysis was employed to identify the clinicopathological factors affecting the postoperative relapse and metastasis.ResultsA total of 112 patients were eligible, including 94 male cases and 18 female cases; age of (58.6 ± 7.7) years; squamous carcinoma of upper thorax in 25 cases, of middle thorax in 67 cases and of lower thorax segment in 20 cases; 12 cases of high-differentiated ESCC, 49 cases of moderate-differentiated ESCC, poorly-differentiated ESCC in 48 cases; 4 cases of I a stage, 9 cases of Ⅰb, 24 cases of Ⅱa, 62 cases of Ⅱb, 13 cases of Ⅲa; the tumor length 〉 4 cm in 43 cases, ≤4 cm in 69 cases. Forty-three (38.4%) patients presented relapse or metastasis during the follow-up, including 24 (21.4%) of loco-regional relapse, 13 (11.6%) of distant metastasi
