Salvage surgery for a locally persistent or recurrent tumour in maxillary cancer patients who have undergone radiotherapy and concomitant intra-arterial cisplatin: implications for surgical margin assessment

Limited information about salvage surgery is available for locally persistent and recurrent maxillary sinus cancers after the completion of chemoradiation therapy. Seventy-six maxillary sinus cancer patients who had undergone chemoradioselection using initial radiotherapy and concomitant intra-arterial cisplatin were screened retrospectively. Twenty-four of these patients who had a locally persistent or recurrent tumour were investigated. The 2-year overall survival rate of patients with maxillary sinus cancer of all types was 39.0% for those who underwent salvage surgery and 10.0% for those who did not.
