Abstract
The numbers of tumor infiltrating T lymphocytes, B lymphocytes and antigen presenting cells were evaluated in an immunohistochemical manner in 140 canine spontaneous mammary gland tumor (MGT) tissues. As a result, we found a statistically significant increase in the number of intratumoral T lymphocytes (23.2 ± 23.8) in the malignant MGT group (n=51) compared with the benign MGT group (14.0 ± 16.0, n=89; P<0.05). Moreover, the high T lymphocyte infiltration in the malignant group correlated with poor prognosis in multivariate analysis (P<0.05). This study indicated the relationship between increased infiltrating T lymphocytes and canine MGT malignancy.
