Results: The relapse rate after orchiectomy alone was 30.6% at 5 years. Presence of vascular invasion together with embryonal carcinoma and rete testis invasion in the testicular primary identified a group with a relapse risk of 50%. Without risk factors, the relapse risk was 12%. Eighty percent of relapses were diagnosed within the first year after orchiectomy. The median time to relapse was…(ver más)
