Therapeutic Targets in Advanced Penile Cancer: From Bench to Bedside.

Simple Summary: Cancer of the penis is a relatively uncommon cancer that nevertheless can be life threatening when it is at an advanced stage. We summarized the published laboratory results that might lead to new and better treatment approaches, including those that harness the immune system. We identified several opportunities for drug development and corresponding clinical trials that are or will soon be testing these ideas in patients. In conclusion, we outline how these ongoing efforts will hopefully improve outcomes for patients with advanced penile cancer. Discovery of effective systemic therapies for patients with advanced penile cancer has been slow to occur. Comprehensive genomic profiling from several studies shed light on the molecular oncogenesis of penile squamous cell carcinoma (PSCC) and differences between HPV-related and unrelated tumors. While these two subsets of PSCC appear distinct in their biology, there are not yet specific treatment strategies recommended on that basis. Cell surface proteins have been identified that may potentially serve as drug targets for monoclonal antibodies or small molecule inhibitors. Here, we review some of the new biological insights regarding PSCC that could lead to improved therapies, as well as the related clinical trials recently completed or in progress. We conclude that antibody-drug conjugates are especially promising, as are the combinations of immune checkpoint inhibitors with other types of drugs. [ABSTRACT FROM AUTHOR]
