Oral squamous cell carcinoma is the most common intraoral malignancy, for which we advocate radical primary resection with adjuvant treatment where indicated. The main aims of this paper are to identify the overall survival of a consecutive series of patients and to relate survival to clinical and pathological factors. Kaplan–Meier curves were produced for site, sex, TNM status, and use of postoperative radiotherapy. The data were analysed using IBM SPSS Statistics for Windows and probabilities of less than 0.05 were accepted as significant. A total of 921 patients were recorded in the database with a diagnosis of oral squamous cell carcinoma out of a total of 1958 with salivary gland conditions or other cancers of the head and neck (43.1%). The earliest date of diagnosis was 1973, and the data were censored at 31 March 2016. The database comprised 340 women (36.9%) and 581 men (63.1%). A total of 339 patients died (34.5%): 117 women (33.7%) and 222 men (65.5%). The mean (range) age at death was 73.4 (31.4–97.5) years for women and 68.7 (33.3–95.5) years for men (t (337)=3.28, p=0.001). Our overall survival was somewhat better than the 56% five-year survival reported for oral cancer in England in 2010, which may be a reflection of the treatment. This work supports the view that aggressive management may improve overall survival.
