Expression of Lewis X Is Associated With Poor Prognosis in Triple-Negative Breast Cancer

Expression of Lewis X Is Associated With Poor Prognosis in Triple-Negative Breast Cancer The Lewis X (LeX) antigen is a prognostic marker in certain solid tumors and has been proposed as a therapeutic target. Immunohistochemical analyses were performed to retrospectively examine the prognostic impact of LeX expression in 158 patients with triple-negative breast cancer (TNBC). Twenty-three (14.5%) patients were LeX-positive. Multivariate analysis showed that LeX positivity was an independent poor prognostic factor for recurrence-free survival (RFS) and overall survival (OS) (P = .037 and P = .024, respectively). LeX expression was a prognostic factor for survival in stage I/II and stage III TNBCs. Subgroup analysis according to age showed that LeX positivity was only associated with poor RFS and OS in younger patients with TNBC (age < 50 years) (P < .001 and P < .001, respectively). Our results suggest that LeX expression is an independent prognostic factor for RFS and OS in younger patients with TNBC. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Clinical Pathology Oxford University Press

Abstract

The Lewis X (LeX) antigen is a prognostic marker in certain solid tumors and has been proposed as a therapeutic target. Immunohistochemical analyses were performed to retrospectively examine the prognostic impact of LeX expression in 158 patients with triple-negative breast cancer (TNBC). Twenty-three (14.5%) patients were LeX-positive. Multivariate analysis showed that LeX positivity was an independent poor prognostic factor for recurrence-free survival (RFS) and overall survival (OS) (P = .037 and P = .024, respectively). LeX expression was a prognostic factor for survival in stage I/II and stage III TNBCs. Subgroup analysis according to age showed that LeX positivity was only associated with poor RFS and OS in younger patients with TNBC (age < 50 years) (P < .001 and P < .001, respectively). Our results suggest that LeX expression is an independent prognostic factor for RFS and OS in younger patients with TNBC.
