[Relationship between T cell infiltration in breast cancer tissues and prognosis]

The relationship between the degree of T cell infiltration in cancer tissues and prognosis was studied in 26 patients with breast cancer. The degree of T cell infiltration was divided into 4 groups according to the number of infiltrating T cells. There was a good correlation between the degree of T cell infiltration and the survival period or disease-free period. It may be clinically useful to check the degree of T cell infiltration in cancer tissues for predicting the prognosis of patients with breast cancer.
