Study on the Polarographic Cancer Reaction Part Ⅰ. Polarographic Cancer Reaction by Serum of the Cancer Patient

The author has performed polarographic cancer tests, first reaction (abb. F.) by the Brdicka's original method, filtrate reaction (abb. D.) by the Muller's method. The positive percentages were; F. 90.9% and D. 81.8% in the gastric carcinoma, both 82.3% in the whole carcinomas. Although each reaction was not specific for cancer, it was aimed to improve the sensitivity, after choosing the distinguished one out of the non-specific: The positive percenteges were 90.9% in the gastric cancer and 88.2% in the whole carcinomas, when they were calculated from the formula F./2D.×15. And the positive percentage revised in accordance with the protein contents was 87.1%. F. in polarographic cancer test, comparing to the others, corresponds to Kurten, Hichijo Black's tests, which determine SH-activate grade. Huggins' and Jensen's reactions revised with the protein contents show similar rate to the Tropp's.
