摘要: PURPOSEWe assessed the prognostic importance of level thymidylate synthase (TS) expression in patients with primary rectal cancer and whether, for Dukes' B C patients, benefit chemotherapy was associated TS expression.PATIENTS AND METHODSThe cancers 294 801 enrolled on protocol R-01 National Surgical Adjuvant Breast Bowel Project (NSABP) immunohistochemically monoclonal antibody 106.RESULTSForty-nine percent whose tumors had low levels (n = 91) were disease free at 5 years compared 27% high 203; P < .01). Moreover, 60% alive after 40% (P The protein significantly stage .01); a more advanced higher TS. remai...
