Sequelae of treatment in long-term survivors of testis cancer.

CONTEXT: Testicular cancer patients are often diagnosed at a young age, and because of the advances in the treatment of this disease, the vast majority have a normal life expectancy after therapy. Thus, recognition of the long-term sequelae of treatment (ie, surgery, radiation therapy, and chemotherapy) is particularly important in these patients.
OBJECTIVE: To review the adverse effects and the risk of secondary malignancy in long-term survivors of testicular cancer. EVIDENCE ACQUISITION: We conducted a Medline search to identify original articles and reviews on the long-term effects of testicular cancer treatment. Although the search included articles from January 1948 to February 2011, the majority of the included articles were published in the last two decades. EVIDENCE SYNTHESIS: All studies examining the long-term sequelae of treatment in testicular cancer are retrospective in nature, with most classified as cohort, case-control, and/or epidemiologic studies. Given that no standardized method of reporting long-term complications exists, evidence synthesis is limited.
CONCLUSIONS: Recent evidence suggests an increased risk of cardiovascular disease, neurotoxicity, and mild reductions in renal function in survivors of testicular cancer. Treatment of testicular malignancy can also negatively affect gonadal function and fertility and has been shown to result in an increased risk of solid malignancy and leukemia.
