[A Case of Early Detection and Treatment Applicable to Squamous Cell Carcinoma of the Palate Detected by Oral Cancer Mass Screening in Izumo 2019].

Treatment of oral cancer is based on radical resection and reconstructive surgery. Surgery causes impairment of maxillofacial morphology and function, including chewing and eating difficulties, and dysarthria. It is necessary to restore the maxillofacial morphology and function by reconstructive surgery and use of prostheses. Therefore, early detection and treatment are required to reduce these disabilities associated with oral cancers. Here, we report a case of oral cancer that was detected early by our oral cancer mass screening program in Izumo, Japan, in 2019. A 73-year-old woman presented with a reddish ulcerative region in the palate. Cytological screening indicated positive-suspected low squamous intraepithelial neoplasia (LSIL). The patient was diagnosed as squamous cell carcinoma of the palate(cT1N0M0, StageⅠ)in our hospital. We performed radical resection of the palate tumor and immediate reconstruction using a vascularized radial forearm flap. The clinical course was good and oral function was fully restored. It is important for oral surgeons to publicize and raise awareness of oral cancer, and to continue oral cancer mass screening programs.
