胃癌复发的类型、时间和危险因素分析

Analysis of patterns, intervals and risk factors for recurrent gastric cancer

目的探讨胃癌复发的类型、复发时间和危险因素,为预测和预防胃癌根治术后复发提供依据。方法回顾性分析1994年8月至1999年8月我科收治的48例胃癌复发病例的复发类型、复发时间和原发胃癌的临床病理特征,并任取我科同期收治的48例无复发胃癌病例作对照。用单因素和多因素分析研究胃癌复发和短期内复发的相关因素。结果单因素分析结果显示,复发组病例术前存在盆腔转移结节、浸润深度达浆膜或浆膜以外以及Borrmann分型Ⅲ型和Ⅳ型的比例明显增多,差异具有统计学意义(P<0.05)。多因素Logistic回归分析表明,浸润深度和Borrmann分型是胃癌复发的高危因素。COX回归分析显示,初发胃癌的浸润深度和腹水是影响胃癌根治手术后早期复发的主要因素。结论Borrmann分型是胃癌复发的高危因素,腹水是影响胃癌根治手术后早期复发的主要因素,而浸润深度既是胃癌复发的高危因素也是胃癌早期复发的主要因素。

Objective To explore the patterns, intervals, risk factors of recurrent gastric cancer and provide evidences for predicting and prevention of recurrence after curative gastrectomy. Methods Forty-eight patients with recurrent gastric cancer after curative gastrectomy for gastric cancer who were operated on in our department from August 1994 to August 1999 were enrolled in this study. Their recurrent patterns, intervals and clinicopathologic characters of primary tumors were analyzed retrospectively and compared with 48 cases without recurrence, who were treated homeochronously and chosen randomly. Risk factors correlated with tumor recurrence and recurrent intervals were studied by univariate and multivariate analysis. Results Univariate analysis showed that patients with metastases node in pelvic cavity, cancer invasion to serosa or more, Borrmann Ⅲ or Ⅳ types were more occurred in recurrent group （ P 〈 0. 05 ）. Multivariate analysis showed the depth of cancer invasion and Borrmann types were independently correlated with tumor recurrence after curative gastrectomy. COX regression analysis showed ascites and depth of cancer invasion were parameters dominating recurrent interval. Conclusions Borrmann type is a risk factor of gastric cancer recurrence, while ascites is a parameter dominating recurrent interval, and the depth of cancer invasion is both risk factor of gastric cancer recurrence and parameter dominating recurrent interval.
