Background:
Advancements in immunotherapy for recurrent head and neck cancer have necessitated a better understanding of salvage surgical outcomes. This study aimed to determine patterns of failure following salvage head and neck surgery.
Methods:
A retrospective cohort study was conducted of 280 patients who underwent salvage surgery for recurrent mucosal squamous cell carcinoma from 1997 to 2018. Cumulative incidence was calculated using the nonparametric Aalen-Johansen estimator. Time to recurrence (TTR) and overall survival (OS) were estimated using the Kaplan-Meier method and multivariable Cox proportional hazard models were used to evaluate associated factors.
Results:
The 2 and 5-year cumulative incidence rates of second recurrence were 48.3 % (95 % CI 42.4-54.3) and 54.9 % (95 % CI 48.9-60.8), respectively. At 5 years, second locoregional recurrence was twice as common as distant recurrence (41.5 % [95 % CI 35.6-47.4] vs. 21.7 % [95 % CI 16.8-26.6]). The median TTR was 21.1 months (95 % CI 4.4-34.8), which varied by site (38.2 larynx/hypopharynx, 13.9 oral cavity, 8.3 sinonasal, and 7.8 oropharynx, P=.0001). The median OS was 32.1 months (95 % CI 24.1-47.6) and was worse for patients who were Black (hazard ratio [HR] 2.15, 95 % CI 1.19-3.9), current smokers (HR 2.73, 95 % CI 1.53-4.88), former smokers (HR 2.00, 95 % CI 1.19-3.35), ≥ 60 years of age (HR 1.41, 95 % CI 1.01-1.97), or received multimodal primary therapy (HR 1.98, 95 % CI 1.26-3.13).
Conclusion:
Rates of recurrence and mortality after salvage surgery were poor but worse for patients who were Black, older, smoked, had initial multimodal therapy, or had sinonasal or oropharyngeal cancers.
