BACKGROUND/AIMS: Few reports from the Western hemisphere have investigated the impact of pathological features and surgical modalities on the prognosis of patients affected by early gastric cancer (EGC). In particular, the extent of lymphadenectomy (limited vs. extended) and the type of gastric resection (subtotal vs. total) remain controversial issues in the management of EGC. The aim of this study was to identify factors influencing prognosis in patients affected by EGC.
Hospital records and pathological specimens of 72 patients with EGC undergoing resective surgery during the period 1981-1995 were retrospectively reviewed. Patient status was determined by follow-up examination or by telephone contact. Univariate and multivariate analysis was used to calculate the 5-year survival probabilities with respect to the following variables: age (< or = 65, > 65), sex, depth of invasion (mucosal, submucosal) tumor location (upper, middle and lower third), gross appearance (type I, type II and type III), size (< or = 1.5 cm, > 1.5 cm), presence or absence of lymph node metastasis, histological type (intestinal, diffuse), extent of lymphadenectomy (limited or extended), and type of gastrectomy (total or distal subtotal). Survival was the outcome variable studied.
Multivariate logistic regression analysis showed that age, nodal involvement and depth of invasion were independently associated with poor survival.
Results showed a significant dominance of host- and tumor-related factors over the type of surgical procedure on prognosis of EGC patients.
背景/目的:西半球鲜有报告研究病理特征和手术方式对早期胃癌(EGC)患者预后的影响。特别是,淋巴结清扫范围(有限清扫与扩大清扫)和胃切除类型(次全切除与全切除)在EGC的治疗中仍是有争议的问题。本研究的目的是确定影响EGC患者预后的因素。
回顾性分析了1981年至1995年间72例行根治性手术的EGC患者的医院记录和病理标本。通过随访检查或电话联系确定患者状态。采用单因素和多因素分析计算以下变量的5年生存概率:年龄(≤65岁、>65岁)、性别、浸润深度(黏膜层、黏膜下层)、肿瘤位置(上、中、下三分之一)、大体形态(I型、II型和III型)、大小(≤1.5 cm、>1.5 cm)、有无淋巴结转移、组织学类型(肠型、弥漫型)、淋巴结清扫范围(有限或扩大)以及胃切除类型(全切除或远端次全切除)。生存是所研究的结局变量。
多因素逻辑回归分析显示,年龄、淋巴结受累情况和浸润深度与生存不良独立相关。
结果表明,在EGC患者的预后方面,宿主和肿瘤相关因素比手术方式具有更显著的主导作用。
