title: Radiologic, clinical and biochemical features of non-seminomatous testicular tumors.
abstract: Current therapy for metastatic non-seminomatous testis tumors is effective but toxic. Careful investigation is needed to select those who need treatment and yet avoid needless toxicity in patients who have no disease. Current radiographic investigations and measurement of two biochemical tumor markers (AFP & BHCG) provided accurate monitoring in 19 patients. Preoperative urography and lymphography correctly predicted the presence or absence of retroperitoneal metastases in 9 of 12 patients but did not show microsocpic metastases in 3. There was good correlation between the clinical, readiographic and biochemical evidence of disease progression and regression. Serial ultrasonography and tumor marker determinations were particularly useful in following asymptomatic abdominal metastases. Radiography and tumor marker determinations each have specific advantages which make them complementary.
