Salvage surgery for recurrent carcinoma of the oral cavity（Original Article）

Abstract

We evaluated 27 cases of salvage surgery for recurrent oral squamous cell carcinoma.
The 1yOS was 75% and 2yOS was 61%. Mean PFS was 10.9 months (2.6–61.3 m).
A pathological resection margin of positive or close, and the primary site in the tongue, oral floor and buccal mucosa were considered as poor prognostic factors. The primary site of re-recurrence in almost 88% of cases was located in the posterior region or parapharyngeal space, so safe setting of the posterior margin and extended dissection of the parapharyngeal space should be considered.
