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.Key words： salvage surgery, head and neck cancer, oral cancer, microvascular anastomoses, free flap Requests for reprints to : Dr. Fushimi C.,
