Testicular seminoma: oncologic rationale and role of surgery in treatment.

ABSTRACT

Seminomas account for approximately 50% of all cases of testicular cancer. Testicular cancer is a highly curable disease that can be broadly classified as either seminomatous or nonseminomatous; the management and treatment of the 2 forms vary widely. Although surgery plays a large role in the management of nonseminoma, its role in the management of seminoma is much more limited. Most clinicians in the United States choose orchiectomy followed by surveillance for patients with stage I seminomatous disease, and chemotherapy or radiation-followed by surgery for the management of residual masses-for patients with disease that is stage II and higher. Recently, clinicians have proposed a larger role for surgery in stage II seminoma to avoid the long-term toxic effects of chemotherapy and radiation therapy. In this review, we discuss the oncologic rationale for the treatment of seminoma, the role of surgery, and the use of minimally invasive operative techniques for retroperitoneal lymph node dissection.
