Prognostic significance of PD-L1 and PD-L2 in breast cancer.

PD-L1 and PD-L2 constitute an important antitumor immune response. In breast cancer, their prognostic value is still to be defined. In this study, we investigate the correlation between PD-L1 and PD-L2 protein expressions with clinical and pathologic features and disease-free survival and overall survival.

Prognostic significance of GRP78 expression patterns in breast cancer patients receiving adjuvant chemotherapy.

This study examined the associations between GRP78 expression and breast cancer recurrence and survival in patients treated with anthracyclines in the adjuvant setting. GRP78 expression was assessed in 106 stage II/III breast cancer patients. Tissue microarray was used to perform immunohistochemistry and to determine the GRP78 expression in endoplasmic reticulum and cell membrane of breast tumors.
