[Thymidylate synthase, thymidine phosphorylase and dihydropyrimidine dehydrogenase expression in soft-tissue sarcoma versus capecitabine potential].

Expression of thymidylate synthase (TS), thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) can predict for clinical outcome of fluoropyrimidine-based therapy and there is every likelihood that relevant tumors will respond. High TP expression was observed in 35 (42%) patients with soft-tissue sarcoma. Seven out of 26 (27%) such patients revealed molecular phenotype prognostically favorable for capecitabine therapy. More clinical research is required to assess the efficacy of capecitabine-based therapy.
