Incidence and clinical outcome of patients with teratoma in the retroperitoneum following primary retroperitoneal lymph node dissection for clinical stages I and IIA nonseminomatous germ cell tumors
Lymph Node Excision
The incidence of teratoma in the retroperitoneum increases with clinical and pathological stage. Teratomatous elements in the orchiectomy specimen predict teratoma in clinical and pathological stage II NSGCT. The absence of teratoma in the primary tumor does not preclude its presence in the retroperitoneum. Primary RPLND avoids the persistence of chemoresistant teratoma in the retroperitoneum, contributes to the high cure rate of patients with low stage NSGCT and decreases the potential for late relapse.
