【Abstract】 The Serum copper and zine levels were measured in 116 subjects. Among them 42 had gastrointestinal carcinoma including 22 large bowel cancer and 20 gastric and esopha-geal cancer; 43 had benign lesions, and 31 were normal. The serum copper level incleased significantly in the patients with gastrointestinal cancer and in those with benign lesions. The Cu Zn ratio was significantly higher in the patients with gastrointestinal cancer than those in the normal subjects and in the patients with benign lesions. It is concluded that in patients with gastrointestinal carcinoma, monitoring with serum copper concentration and copper/zinc ratio are of clinical value.更多还原
