[T-cell bearing IgG-Fc receptor in patients with bladder cancer].
The T-cell bearing Fc receptor (IgG-FcR+ T cell) has been considered as a suppressor or a part of the killer cell, as determined by its function. The population of IgG-FcR+ T cells was determined by Moretta 's method in patients with urinary bladder cancer, urological benign diseases and in normal subjects. The population of IgG-FcR+ T cells in the peripheral lymphocytes of 16 patients with urinary bladder cancer was 20.5 +/- 10.1%, that of 7 patients with urological benign diseases was 9.5 +/- 3.2%, and that of 8 normal subjects was 9.0 +/- 2.1. The population of IgG-FcR+ T cells in the peripheral lymphocytes patients with high stage bladder cancer was significantly higher than that of patients with low stage cancer. In low stage bladder cancer cases, the population of IgG-FcR+ T cells was decreased to the normal range at three weeks after removal of the tumor. But in high stage bladder cancer cases, it was not changed at 3 weeks.
