Abstract
Serum calcium figures in stomach cancer were studied with special interest to their relation with the morphological aspects of the lesion, taking ionization of serum calcium into consideration.
1) The concentration of serum calcium, especially that of the ionized calcium, was generally low in stomach cancer, and significantly lower even when compared with peptic ulcer cases. The abnormal patterns of serum calcium, defined from both the concentration and the extent of dissociation, were found in 89.6 per cent of the stomach cancer cases.
2) The serum calcium figures in stomach cancer were closely dependent upon the extent of the cancer spreads that was revealed by operations, a little upon the tumor size, but wholly not upon the gross nor microscopic features of the tumor.
