纽约Sloan-Kettering癌症中心的Dr.Lawrence S.Engel及其同事指出,在一般的人群中大多数食道癌和胃癌是由主要危险因素引起的。虽然有许多报告报道了一些导致这些癌变的危险因素,但尚无一项研究全面地检查这些危险因素引起人群肿瘤负担中的作用。 本报告是一份以人群为基础的研究,包括了1143名食道癌或胃癌的病人,以及695名对照健康人群。 Dr. Lawrence S. Engel of Sloan-Kettering Cancer Center in New York and colleagues point out that the majority of esophageal and gastric cancers in the general population are caused by major risk factors. Although there are many reports on some of the risk factors leading to these cancers, no study examines the role of these risk factors in the population’s tumor burden. This report is a population-based study of 1143 patients with esophageal or gastric cancer and 695 healthy controls.
