Abstract
An attempt was made to investigate the early diagnosis of cancer and the effect of surgical operation to the patients by using paperchromatography for detecting some substances (not identified) in the urine qualitatively. By the method previously reported (Iryo, Vol. 20, No. 10, p. 49-52), cancer patients could be distinguished from non-cancer patients significantly. The present investigation was made to observe the effect of surgical operation on the urinalysis. Remarkable difference between before and after the operation of cancer was recognized on the urinalysis statistically, of the 144 patients with gastric cancer, only 1 was negative and 12 patients were doubtful, Of the 216 patients with cancer of some organ, 7 were negative and 22 were doubtful.
Further experiment is undergoing the effect of chemotherapy to cancar patients on the urinalysis.
