General Information About Penile Cancer
Incidence and Mortality
Estimated new cases and deaths from penile (and other male genital) cancer in the United States in 2014:
- New cases: 1,640.
- Deaths: 320.
Penile cancer is rare in most developed nations, including the United States, where the rate is less than 1 per 100,000 men per year. Some studies suggest an association between human papillomavirus (HPV) infection and penile cancer.[2-5] Observational studies have shown a lower prevalence of penile HPV in men who have been circumcised (odds ratio, 0.37; 95% confidence interval, 0.16–0.85). Some, but not all, observational studies also suggest that male newborn circumcision is associated with a decreased risk of penile cancer.[7,8] According to published data, if the relationship is causal, the number needed to treat was about 909 circumcisions to prevent a single case of invasive penile cancer.
When diagnosed early (stage 0, stage I, and stage II), penile cancer is highly curable. Curability decreases sharply for stage III and stage IV. Because of the rarity of this cancer in the United States, clinical trials specifically for penile cancer are infrequent. Patients with stage III and stage IV cancer can be candidates for phase I and phase II clinical trials testing new drugs, biologicals, or surgical techniques to improve local control and distant metastases.
