摘要
During 1984 to 1990, a comparative etiologic studyand primary prevention for stomach cancer was carriedout in a high risk area in Zhuanghe County of LiaoningProvince. Because of the increase of consumption of fr-esh vegetables and fruits (Protective factors), decreaseof eating salted pork and fishes which was verified tohave strong mutagenecity (risk factors), acute inflamma-tion and erosions accompanying with chronic gastritis havegot striking improvement. At the same time, serum betac-arotene also raised gradually. The authors stressed thatimprovement of economic situation and dietary habits mayplay an important role in primary prevention of precurso-res of stomach cancer but decrease of incidence of thiscancer is an event of 30 years or more later as the letentperiod of stomach cancer is rather long.
