Surveillance after orchiectomy for stage I seminoma of the testis.

Between February 1983 and July 1985, 52 patients with Clinical Stage I seminoma were observed after orchiectomy without lymph node irradiation. Seven patients (13%) have relapsed, six in retroperitoneal lymph nodes and one with abdominal node and pulmonary metastases. Relapses were diagnosed 6 to 23 months after orchiectomy, four occurring in the first year and three in the second year. Of eight patients with raised serum concentrations of HCG prior to orchiectomy none has relapsed, whereas of 14 patients with normal HCG levels one has relapsed. The significance of these observations for future management policy is discussed.
