The management of carcinoma in situ (CIS) of the penis is controversial, with relatively high local recurrence rates after minimally invasive therapies.Report the surgical technique and outcome of partial glans resurfacing (PGR) and total glans resurfacing (TGR) as primary treatment modalities for CIS of the glans penis.Between 2001 to 2010, 25 patients with biopsy-proven CIS underwent TGR (n=10) or PGR (n=15), defined as <50% of the glans requiring resurfacing. All patients were surveyed clinically every 3 mo for 2 yr and every 6 mo thereafter.Excision of the glans epithelium and subepithelium of either the entire glans or the locally affected area, with a macroscopic clear margin. The penis was then reconstructed using a split skin graft.Positive surgical margin (PSM) rates and rates of recurrence and progression were collated. Complications, cosmesis, and patient satisfaction were evaluated.Mean follow-up was 29 mo (range: 2–120 mo). There were no postoperative complications, and 24 of 25 patients (96%) had complete graft take with excellent cosmesis. Overall, 12 of 25 patients (48%) had PSMs. Only 7 of 25 (28%) required further surgery, 2 of 25 (8%) for extensive CIS at the margin and 5 of 25 (20%) for unexpected invasive disease. Additional surgery consisted of further resurfacing in 4 of 25 cases (16%) or glansectomy in 3 of 25 cases (12%). Those undergoing further surgery had no further compromise to their oncologic outcome. The overall local recurrence rate was 4%. There were no cases of progression.Glans resurfacing is a safe and effective primary treatment for CIS. The procedure maintains a functional penis without compromising oncologic control, while ensuring that definitive histopathlogy is obtained. Glans resurfacing has a low risk of recurrence and progression. Patients need to be warned that approximately 28% will require further surgery for PSM or understaging of their primary disease, although the need for further surgery does not compromise oncologic control.
