Late recurrence of clinical stage I seminoma of the testis after 12 years despite adjuvant infradiaphragmatic irradiation.

A patient treated with prophylactic infradiaphragmatic radiation therapy for clinical stage I left testicular pure seminoma developed a large mass of the chest wall 12 years after primary treatment. An incisional biopsy confirmed pure seminoma. After chemotherapy, surgical removal of the residual mass and second-line chemoradiation therapy for persistent seminoma, the patient had a vertebral relapse. He died of progression 24 months after the first relapse despite further therapy. Copyright 2004 S. Karger AG, Basel
