Treatment of a population based sample of men diagnosed with testicular cancer in the United States.

Objectives: Testicular cancer is the most common cancer in men age 25 to 35 years. We examined therapy, compliance with guidelines, and survival in a population based sample of men newly diagnosed with testicular cancer.

Materials And Methods: We analyzed the National Cancer Institute's (NCI) patterns of care data on 702 men diagnosed with testicular cancer in 1999. These studies supplement routine data collection by verifying therapy with the patients' treating physicians. Follow-up for vital status was available through December 31, 2004.

Results: The majority of the men with seminoma were diagnosed while their cancer was localized and more than 80% of received orchiectomy with radiation. For men with seminoma and nonseminoma germ cell tumors (NSGCT), the percent receiving chemotherapy increased markedly as stage increased. More than 90% of men with regional and distant NSGCT received chemotherapy. Less than 25% of men with localized NSGCT received orchiectomy and retroperitoneal lymph node dissection (RPLND), about 40% had surveillance following an orchiectomy alone, and 30% received orchiectomy and chemotherapy.

Conclusions: The majority of these patients received therapy consistent with guidelines. While there was no significant difference in the use of RPLND in men with localized NSGCT by geographic region, chemotherapy use varied widely. Over 90% of men with localized or regional disease diagnosed in 1999 were alive at the end of 2004. The excellent survival rates point to the need to monitor for late effects of therapy.
