In addition, the presence of TIB cells was found to be correlated with overall and progression-free survival in basal-like breast cancer patients, HER2-enriched breast cancer patients, and immunoreactive ovarian cancer patients; furthermore, B cell gene expression was highly correlated with T cell gene expression in tumors, suggesting that B cells may cooperate with T cells in antitumor immunity. The gene discussed is ERBB2; the disease is breast carcinoma.
