Squamous cell carcinoma (SCC) of the penis is an uncommon disease in the US and Europe. Without treatment, patients with penile SCC usually die within 2 years after diagnosis of the primary lesion, because of uncontrollable locoregional disease or from distant metastases. The spread of the tumor to the locoregional lymph nodes (lymph-node positivity) is the most relevant prognostic factor. With the available treatments, 5-year cancer-specific survival probabilities are between 75% and 93% for those patients with clinically node-negative disease, and progressively lower for those with increasingly extensive node-positive disease. Similarly, patients with pathologically proven negative nodes have 5-year cancer-specific survival probabilities ranging from 85% to 100%. While patients with a single positive superficial lymph node on pathology have very good cancer-related outcomes, patients with multiple involved lymph nodes have significantly less favorable outcomes. This article focuses on the most important issues that surround the prognosis of squamous cell carcinoma of the penis, with special attention to the prognostic nomograms for penile cancer patients published in 2006.
