[Clinical study on tissue polypeptide antigen (TPA) in gastric cancer].
We evaluated whether assay of tissue polypeptide antigen (TPA) in the serum ia valuable for the determination of cancer stages compared to other tumor markers such as CEA, AFP, and ferritin. The study population consisted of 79 gastric cancer patients and 212 patients with benign gastroenteric disease. The percentage of positive cases for TPA (higher than 200u/l) was 41% in gastric cancer and 20% in active peptic ulcer. Serum TPA levels in well differentiated carcinoma and signet ring cell carcinoma were higher than that in other histological types. Serum TPA levels correlated well with the stage of the gastric cancer.
