Sexual function in the penile cancer survivor: a narrative review.

Abstract

Squamous cell carcinoma of the penis is a rare malignancy among men in North America and Europe with an incidence of <1 per 100,00 men. Of all genitourinary cancers, penile carcinoma has the potential to jeopardize sexual function the most. The treatment modalities of penile carcinoma span the gamut from organ-sparing treatments such as topical therapy, laser therapy, radiotherapy, glansectomy, wide-local excision and partial or total penectomy. There is a relative paucity of data in the medical literature describing the impact of penile cancer treatment on sexual function. The majority of available studies use retrospective data from small samples utilizing heterogeneous study tools such as patient interviews and non-validated questionnaires. The most commonly used validated instrument to evaluate sexual outcomes is the International Index of Erectile Function Questionnaire (IIEF), but is limited in that it does not assess patients who perform self-stimulation or achieve sexual stimulation by any means other than penetrative intercourse. Though advances in clinical research continue; large, well-designed comparative studies using validated instruments are elusive. The sexual outcomes after penile cancer are reviewed from the available published data to better assist the patient and the treating physician with medical decision making. With a detailed assessment of sexual outcomes, the physician is better equipped in providing patient centered care to achieve outcomes meaningful for each patient.
