PURPOSE: Regionally metastatic cutaneous squamous cell carcinoma of the head and neck (CSCCHN) is usually managed surgically; however, the role of parotidectomy remains controversial. Herein we elucidate the controversy and present our experience.
METHODS: We retrospectively analyzed disease variables, extent of parotidectomy, and pathologic characteristics in association to outcome measures of all advanced CSCCHN patients who underwent definitive surgical resection from 2008 to 2018.
RESULTS: Sixty-seven patients were enrolled, of whom 47 (70%) underwent parotidectomy; 27 superficial and 20 that included deep lobe resection. Parotidectomy had improved 5-year overall survival (OS) and disease-free survival (DFS) when neck was clinically involved (67.6% vs. 22.2%, P = 0.003 and 75.8% vs. 33.3% P = 0.002, respectively). Elective parotidectomy did not confer survival benefit for patients with no clinical involvement of the parotid gland (41.7% vs. 35%, P = 0.977). Recurrent disease was predictive for parotid metastases (P = 0.034). Thirty-nine patients received adjuvant radiotherapy, which significantly improved OS and DFS versus surgery alone (70.7% vs. 38.1%, P = 0.004 and 77.8% vs. 57.9%, P = 0.014, respectively).
CONCLUSION: Parotidectomy was associated with improved survival of cervically spread CSCCHN.
