Studies on the serum TA-4 levels of patients with oral cancers

Abstract

Serum TA-4 was examined in patients with oral diseases and the following results were obtained.
1) TA-4 was peculiar to oral squamous cell carcinoma.
2) TA-4 was useful to diagnose patients in progressive stages, though it was not helpful with patients in early stages.
3) TA-4 was more sensitive than other tumor markers.
4) Serum TA-4 levels reflected the conditions of patients quickly, so TA-4 may be useful for evaluating regression or progression and detecting recurrence in oral squamous cell carcinoma.
