Abstract
Penile cancer is a rare disease. This has led to little in the way of therapeutic advances in the last two decades. Efforts have been made to minimize the use of disfiguring or morbid procedures in treating the primary tumor or managing the inguinal region. In addition, new insights have been gained into multimodal therapy for treating metastatic disease. We reviewed the literature published during the past two years to define the recent insights into the diagnosis and management of penile cancer. Surveillance, Epidemiology and End Results Program data revealed poor outcome among African-American patients compared with Caucasians with penile cancer. Risk factors, including human papilloma virus, HIV, and the practice of circumcision have been reassessed. To improve diagnosis and staging, new modifications in imaging have been developed including magnetic resonance imaging with artificial erection. In addition, the technique of dynamic sentinel node biopsy has been refined. Pathologic features of the primary tumor (i.e., stage, grade, vascular invasion) assist in identifying patients who would benefit from lymphadenectomy. Organ-sparing treatments using laser ablation and reconstructive procedures to preserve glans or phallus length have also been developed. Systemic chemotherapy regimens, including consolidative approaches with surgery or radiotherapy, are discussed for advanced penile cancer. Penile cancer remains a rare disease. Epidemiologic insights reveal provocative findings with respect to risk factors and racial differences in the outcome. Recent literature provides information that will aid urologists in (1) minimizing the need for disfiguring treatment of penile tumors in some patients and (2) reducing the number of unnecessary inguinal staging procedures in others. Novel systemic therapies that generate durable responses tested in multi-institutional treatment trials are needed.
