title: Reliability of diagnostic imaging after orchiectomy alone in follow-up of clinical stage I testicular carcinoma: excessive cost with potential risk.
abstract: From 1981 to 1984, 86 consecutive patients with previously untreated nonseminomatous testicular carcinoma were classified as clinical radiological stage I and treated with orchiectomy alone. The follow-up program included chest x-ray and lymphangiography (LAG) every month and abdominal computed tomography (CT) bimonthly. All patients were followed for 15 to 63 months after orchiectomy (median 32 mo.). Metastases developed in 23 patients (26.7%) and in 13/23 there was retroperitoneal lymphadenopathy. Time of relapse after orchiectomy ranged from 2 to 36 months (median 7 mo.) with a shorter interval for chest (4 mo.) compared with retroperitoneal metastases (7 mo.). Lung metastases were readily identified at an early stage (less than 2 cm) whereas more than one-third of retroperitoneal nodal metastases were greater than 5 cm at time of diagnosis. LAG detected metastases in 8/11 patients (72.7%), abdominal CT in 8/10 (80%), and both together (LAG and CT) 7/8 (87.5%). In clinical stage I nonseminomatous testicular carcinoma, the high incidence of concomitant but often asymptomatic regional and distant metastases and the relatively high cost and inconvenience of follow-up using abdominal CT imaging, LAG and chest x-ray suggest that orchiectomy is best combined with retroperitoneal node dissection at time of initial presentation to insure more accurate and safe staging of tumor dissemination.
