title: [Changes in immunoparameters following cryosurgery in prostate cancer].
abstract: To determine the effect on immunoparameters of cryosurgery in cases of stage B prostatic cancer and to determine whether such changes were specifically related to the cryosurgery technique, immunoparameters were measured and compared with cases of prostatic hyperplasia treated by transurethral resection (TUR-P). A decrease in immunoparameters was recognized in the cryosurgery group at 1-3 days postoperatively (increase in IAP, decrease in NK cell activity, decrease in lymphocyte blastogenesis reaction to PHA). The protein histograms, immunoglobulin and IAP changed similarly after the two above procedures. These changes were thought to be due to the invasive nature of the procedures. However, some difference was seen between the cryosurgery group and the TUR-P group in terms of rate of lymphocyte blastogenesis reaction to PHA and Con A, IgG, complement and NK cell activity which might indicate a specific effect of cryosurgery different from TUR-P.
