Metastatic Tumors Involving the Testes
摘要
From 1979 to 1999, totally 200 cases of testicular tumor were diagnosed and treated at Taipei Veterans General Hospital. With the exception of lymphoma and leukemia, a total of 14 cases with metastatic tumor to the testis was collected. Eight cases(51.7%)were derived from adenocarcinoma of the prostate, 2 cases(13.6%) from lung cancer, 2(13.6%) from cancer of the gastrointestinal tract, 1(7.1%) from carcinoma of the seminal vesicles and 1(7.1%) from undetermined origin. There were 2 cases with bilateral testicular involvement(13.6%), and another 12 cases were unilateral involvement as well as all cases combined with multiple metastases. Nine cases(64.3%) presented with a scrotal mass without elevation of AFP or B-HCG clinically, and 5 cases were discovered incidentally ofter therapeutic orchiectomy due to adenocarcinoma of the prostate. One of the 14 cases was still alive. In the 13 expired cases, the average survival was 12.8 mo for the 7 patients with prostate cancer after orchiectomy and 7.4 mo for the 6 non-prostate cancer patients. Prognosis was very poor in metastatic carcinoma to the testis due to the late stage.
