Immune effect of tumor-infiltrating lymphocytes and its relation to the survival rate of patients with ovarian malignancies.
Tumor-infiltrating lymphocytes (TIL) in histological sections from 94 patients with ovarian malignancies were quantitated for their relation to the prognosis of the patients. It was found that the degree of lymphocyte infiltration directly affected the patients' survival rate and also related to clinical staging of the patients, as well as grading and histologic typing of the tumor. T lymphocytes characterized by alpha-naphthyl acetate (ANAE) staining were the major cells in the stroma of ovarian malignancies. Ultrastructural study of TIL and cancer cells suggested that tumor cell degeneration is related to the effect of TIL.
