    Author: Wang CS.
    Journal: Zhonghua Wai Ke Za Zhi; 1989 Jul; 27(7):401-3, 444. PubMed ID: 2598740.
    Abstract:
    The serum copper and zinc Levels of 35 cases of gastric cancer were measured pre- and postoperatively, and Cu and Zn Levels in their gastric juice were also determined Preoperatively. The results Showed that serum copper Levels (SCL) and Cu/Zn ratios of patients with gastric cancer were significantly higher, while serum zinc levels (SZL) lower than those of the control. In addition, SCL of patients with gastric cancer elevated progressively as the cancer advanced. After resection of the tumor, SCL and Cu/Zn ratio declined and SZL elevated again. The Cu and Zn levels in the gastric juice, of benign gastric lesions showed more marked elevation and gastric cancer patients had higher Zn level than those in the normal controls.
