ESOU18: Conservative Surgery for Penile Cancer: Indications and Techniques

Amsterdam, The Netherlands (UroToday.com) Penile cancer accounts for 0.4%-0.6% of all malignant neoplasms among men. The mean age is 55-58 years, but 22% of men are younger than 40, and 7% are younger than 30. The incidence in western countries is very low (0.1-0.9/100,000 in Europe) – with 400 new cases per year in the United Kingdom. In contrast, in Uganda and Paraguay the incidence is as high as  4.2-4.4/100,000 men. 

Known risk factors include phimosis, chronic penile inflammation, sporalene and ultraviolet A phototherapy for various dermatological conditions such as psoriasis. Additional risk factors include smoking, human papilloma virus infection, rural areas and low socioeconomic status, and history of multiple sexual partners with early age at first intercourse. Figure 1 demonstrates the distribution of cases diagnosed by anatomical site, and figure 2 shows the most recent 8th TNM staging of penile cancer. 

The traditional management included radical surgery, with excision of the lesion and a 2 cm margin.  This resulted in excellent oncological control with a 0.7% and 4.6% recurrence rate after total penectomy and partial penectomy, respectively.  However, this also resulted in poor cosmetic and functional results with significant psychological and sexual morbidity.  It has been shown that patients having more mutilating surgery, were more likely to have impaired well-being, pathologic anxiety (31%), post-traumatic stress disorder (40%), and avoidance behavior (25%). Therefore, there has been an attempt to use penile preserving surgery instead, in order to avoid the significant emotional and sexual morbidity associated with radical surgery.

The European association of Urology (EAU) guidelines recommend obtaining a penile MRI with artificial erection in cases for which organ preserving is intended. MRI results have demonstrated good correlation to histologic staging, with the following stage specific sensitivities and specificities calculated: T1 (85%, 83%), T2 (75%, 89%), and T3 (88%, 98%). MRI accurately predicted corpora cavernosum invasion in all cases of pathologically proven disease.

There is lack of high quality data regarding quality of life in penile cancer. Most studies are retrospective with small numbers of patients, with no standardization of methodology, or of treatment groups. It is important to standardize the method of assessment to accurately clarify  the impact of disease and treatment type on quality of life, so that we could further refine management.
