限局性前立腺癌21例に対してstaging pelvic lymphadenectomyを施行した.1) 12例,57%の例に転移をみた.2)リンパ管造影を施行した4例は,いずれも正診をえなかった.3)血中酸性フォスファターゼ値と転移の有無は関係なかった.4)リンパ節転移を有するものの原発巣の病理組織分化度は,転移のないもののそれより低分化傾向を示した.5)転移を有する例で,外腸骨リンパ節,内腸骨リンパ節および閉鎖リンパ節は,それぞれ55%,83%,82%の例に転移をみた.6)術後合併症は,創し開,下肢浮腫をそれぞれ1例にみたStaging pelvic lymphadenectomy was performed on 21 patients with the prostatic cancer of stage A, B and C from January in 1981 to April in 1985. Twelve cases (57%) showed lymph node metastasis. Gleason's scores of the cases with lymph node metastasis proved lower than those of the cases without lymph node metastasis (p less than 0.05). There were no differences in grade between primary tumors and lymph node metastases. The percentage of metastasis to the external iliac, internal iliac and obturator lymph nodes was 55%, 83% and 82%, respectively. Two patients suffered from the delayed healing of the wound and the edema of the lower extremities, respectively, but the other patients had no complication.
