We identified p53, p27kip1, Ki67, matrix metalloprotease-9, survivin, Ki67 proliferative index, CD133, COX2, CD44v6, thymidylate synthase, thymidine phosphorylase, and dihydropyrimidine dehydrogenase as the most common markers studied in literature to date, and we explained their prognostic potential and their implications in the evaluation of the response to preoperative therapies in rectal cancers.
Increase in Gene Expression of TYMP, DPYD and HIF1A Are Associated with Response to Preoperative Chemoradiotherapy Including S-1 or UFT for Rectal Cancer.
High TS and DPD mRNA levels on FFPE specimens may predict distant recurrence of rectal cancer treated with 5-FU-based preoperative CRT followed by surgery.
This work is intended to study the effect of preoperative capecitabine and radiotherapy treatment on the levels of thymidylate synthase (TS), thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) mRNAs in rectal carcinoma.
Prognostic value of histologic tumor regression, thymidylate synthase, thymidine phosphorylase, and dihydropyrimidine dehydrogenase in rectal cancer UICC Stage II/III after neoadjuvant chemoradiotherapy.
