Abstract
OBJECTIVE: To determine factors associated with local recurrence (LR) of oral squamous cell carcinoma involving the maxillae (MSCC) and overall survival (OS) after salvage treatment.
SUBJECTS AND METHODS: Retrospective study of MSCC operated between 2000 and 2015. Kaplan-Meier survival and Cox regression were used for analysis of MSCC-associated clinical and histopathological factors.
RESULTS: Ninety-five patients were included. LR occurred in 24% of patients. Vascular invasion significantly increased the risk of LR (hazard ratio 4.595, P = .003). Local salvage surgery, in the area of the original tumor, significantly prolonged OS, compared to palliative treatment (P = .001) and extensive salvage surgery (P = .013). Extensive salvage surgery, requiring resection of adjacent facial structures, did not prolong OS compared to palliative treatment (P = .186).
CONCLUSIONS: MSCC with vascular invasion has higher risk of LR. Salvage surgery may prolong OS in small recurrences but might have dubious value for larger recurrences infiltrating adjacent facial structures.
