Simple Summary: Oral squamous cell carcinoma is a global health concern, particularly affecting the South Asian population. The South Asian community is among Canada's largest and most rapidly expanding minority groups. This study compared the outcomes of South Asian patients with oral squamous cell carcinoma to the general population at a Canadian cancer center. In total, 697 patients who underwent surgery for oral squamous cell carcinoma between 2009 and 2022 were evaluated, with South Asian patients constituting 9% of the cohort. Despite similar tumor characteristics and treatments, South Asian patients had double the risk of cancer recurrence and significantly worse survival compared to non-South Asian patients. Understanding the association between South Asian ethnicity and outcomes in OSCC is crucial for informing public health initiatives to meet the distinctive needs of this population, thus fostering a more inclusive and supportive environment. (1) Background: To compare oncologic outcomes of South Asian (SA) patients treated for oral squamous cell carcinoma (OSCC) to the general population. (2) Methods: Adult patients who underwent surgical resection of OSCC +/− adjuvant treatment between 2009 and 2022 (N = 697) at a regional cancer centre in Canada were included. SA patients, identified using a validated method, were compared to non-SA patients. Kaplan–Meier methods were used to compare the primary outcomes, disease-specific survival (DSS) and recurrence-free survival (RFS) across baseline univariate characteristics, including betel nut consumption. Median follow-up time was 36.4 months. Cox proportional hazard models were used to identify independent predictors of survival with significance set at p < 0.05. (3) Results: SA patients (9% of cohort, N = 64) were significantly younger and had lower rates of smoking and alcohol consumption compared to non-SA patients (p < 0.05). SA patients had a two-fold higher risk of recurrence and significantly worse disease-specific survival, even after adjusting for stage and high-risk features [RFS: HR 2.01 (1.28–3.14), DSS: HR 1.79 (1.12–2.88)]. The consumption of betel nut was not associated with outcomes. (4) Conclusions: SA patients had significantly worse oncologic outcomes, even after controlling for known predictors of poor prognosis. These findings are novel and can inform personalized treatment decisions and influence public health policies when managing patients with different ethnic backgrounds. [ABSTRACT FROM AUTHOR]
