Teratoma in the orchiectomy specimen and volume of metastasis are predictors of retroperitoneal teratoma in low stage nonseminomatous testis cancer.

Abstract

We determined whether teratomatous elements in the orchiectomy specimen predict for teratoma in the retroperitoneum in patients who have not received chemotherapy. We retrospectively reviewed the records of patients with clinical stages A, B and B2 nonseminoma who underwent retroperitoneal lymph node dissection. Teratomatous elements in the orchiectomy specimen predict for retroperitoneal teratoma. When deciding on treatment for low stage nonseminoma, the presence or absence of teratoma in the orchiectomy specimen should be considered to minimize double therapy.
