Primary squamous cell carcinoma of the scrotum: Outcomes from a specialist center

Abstract

Background: Squamous cell carcinoma (SCC) of the scrotum is a rare and aggressive cancer. There are no established guidelines on the management of scrotal SCC. Objective: To analyze the clinical management and outcomes of scrotal SCC. Patients and methods: A retrospective analysis of patients diagnosed with primary scrotal SCC over a 10-year period was performed. The type of surgery, tumor stage and histological subtypes, recurrence rate and metastases, cancer-specific mortality (CSM), and other-cause mortality (OCM) were analyzed. Results: Between 2012 and 2022, a total of 10 men were identified with primary scrotal SCC. The median (interquartile, IQR) age was 65.5 (55–77) years. Wide local excision was performed in 9 patients and 1 patient underwent a total scrotectomy. The pathological T-stage was: pT1, n = 3; pT2, n = 1; pT3, n = 5 (50%); pT4, n = 1. Four patients had pathologically positive inguinal lymph nodes and 2 had distant metastatic disease at presentation. At a median (IQR) follow-up of 10.5 (4–31) months 5 patients died, of which 3 died from scrotal SCC. Conclusion: Scrotal SCC is extremely rare in the UK with only 10 primary cases identified in our center over the past 10 years. Surgical resection of the tumor and appropriate inguinal node staging are required due to a high proportion of cases which metastasize to the inguinal lymph nodes. Patient Summary: Scrotal cancer is rare. 10 cases were diagnosed over 10 years at a single center. Around half had disease spread to the groin nodes or distant organs at presentation. Surgical resection was required in all patients. At the time of analysis, half of the patients are alive. Due to the rarity and aggressiveness of the cancer, management should be carried out within a specialist center.
