Surgical management of recurrent cutaneous squamous cell carcinoma of the head and neck after definitive surgery and radiotherapy.

Background: Surgery is the primary treatment for patients with recurrent head and neck cutaneous squamous cell carcinoma (cSCC) who have previously been treated by definitive surgery and radiotherapy. There are limited published data to direct management and the role of immunotherapy is currently under evaluation.

Methods: This was a retrospective study of patients with at least stage III recurrent head and neck cSCC previously managed by definitive surgery and radiotherapy.

Results: A total of 30 patients met the inclusion criteria. Eighty-seven percent were male and the median age at the time of surgery was 79 years. After salvage surgery, 7% developed local recurrence and 43% regional or distant failure. The 2-year overall survival and disease-free survival were 45% (95% confidence interval 24-64) and 11% (95% confidence interval 1-34), respectively. Advanced age was associated with a higher risk of overall mortality (P < 0.05).

Conclusion: Patients with recurrent head and neck cSCC in the setting of previous radiotherapy have high recurrence rates with poor survival justifying consideration for treatment with anti-PD-1 immunotherapy strategies.
