Radiotherapy approaches for locally advanced penile cancer: neoadjuvant and adjuvant.

PURPOSE OF REVIEW: As penile cancer is an uncommon malignancy in the Western society, randomized trials to address the controversies in management have not previously been undertaken. The incorporation of multidisciplinary approaches in the management of advanced penile carcinoma has largely borrowed evidence from analogous malignancies in the anogenital region. This review is being undertaken in preparation for the international launch of InPACT, the International Penile Advanced Cancer Trial, a collaborative effort from European and North American trialists.

RECENT FINDINGS: The literature supporting the development of this trial is reviewed, along with the trial design, goals, and endpoints. Level one evidence of the benefits of combined chemo-radiotherapy in the management of squamous cell carcinoma of the cervix, oropharynx, vulva, and anal canal has led to the introduction of this approach for advanced penile cancer. InPACT will compare chemo-radiotherapy to the traditional surgical approach, with or without neoadjuvant chemotherapy.

SUMMARY: InPACT will define the roles and optimal sequencing of surgery, chemotherapy, and radiotherapy in advanced penile cancer. In the meantime, this collaborative effort among the major research consortiums of Europe and North America lends credibility to the application of this evidence to the penile site.
