title: [Marked effectiveness of the LH-RH analogue in a case of prostate cancer with large lymph node metastasis].
abstract: A 78-year-old man visited our hospital complaining of pollakisuria, dysuria, and edema of lower extremities. Physical examination revealed a hard, fixed and fist size mass in the abdomen Lymph nodes of left supraclavicular fossa were hardly palpable. His prostate was larger than a hen's egg, stony hard and fixed in the pelvis on digital rectal examination (DRE). The prostate specific antigen (PSA) level was elevated to 584 ng/ml. Computerized tomography (CT) revealed enlarged retroperitoneal lymph nodes. Bone scan showed multiple abnormal uptake. Prostate biopsy showed poorly differentiated adenocarcinoma. Treatment with the LH-RH analogue was very effective. The retroperitoneal lymph nodes were no longer enlarged on CT. The prostate had become soft and was reduced to walnut size on DRE. The PSA level had decreased to within the normal range. The multiple abnormal uptake on the bone scan decreased. This is the 21st case of prostate cancer with large lymph node metastasis in Japan.
