Humoral immune response to thymidylate synthase in colon cancer patients after 5-FU chemotherapy

Immunol Lett. 2005 Aug 15;100(1):88-93. doi: 10.1016/j.imlet.2005.06.011.

Abstract

Thymidylate synthase (TYMS), the critical enzyme for DNA synthesis and a target for chemotherapy, was recently characterized as an oncogene and a potential target for specific immunotherapy. Here we report TYMS-specific antibody response in a fraction of colon cancer patients. Humoral immune response to TYMS is induced by chemotherapy using TYMS inhibitors, such as 5-fluorouracil (5-FU), and may be associated with tumor burden. Therefore, TYMS may serve as a useful serological biomarker for monitoring the course of disease and treatment in cancer patients.
