Phyllodes type of atypical prostatic hyperplasia.

This report documents an uncommon prostatic hyperplasia which developed within,1 thick capsule between the bladder and rectum grossly showing a phyllodes type ot growth. It was simply excised, but recurred locally two years later. A total prostatectomy was performed, and microscopic examination of the tissue revealed no malignant transformation.

[Histological effects of hormono-chemotherapy on prostatic cancer].

Using new criteria for histological effects of anti-cancer treatment, the effects of hormono-chemotherapy on 10 patients with prostatic cancer not previously treated were compared with those on 10 patients who received conventional hormone therapy. Marked effects were observed in 4 (40%) patients received hormono-chemotherapy but not observed in patients who received conventional hormone therapy (chi 2 test, p less than 0.05). All four cases who showed marked effects were in stage B at the beginning of treatment. Hormonal effects were more obvious in well differentiated cancer, and the effects of chemotherapy were observed in some cases with moderately and poorly differentiated cancer. Therefore, the addition of chemotherapy is recommended as the initial therapy on prostatic cancer to reduce the relapsing rate, especially for patients with poorly and moderately differentiated cancer.
