الوصف: Background To compare the clinical outcomes of two treatment modalities, initial surgery and primary definitive radiotherapy (RT), in Taiwanese patients diagnosed with cT1−2N0M0 oral cavity squamous cell carcinoma (OCSCC). Methods Between 2011 and 2019, we analyzed data for 13,542 cT1−2N0M0 patients who underwent initial surgery ( n = 13,542) or definitive RT with a dosage of at least 6600 cGy ( n = 145) for the treatment of OCSCC. To account for baseline differences, we employed propensity score (PS) matching, resulting in two well‐balanced study groups (initial surgery, n = 580; definitive RT, n = 145). Results Before PS matching, the 5‐year disease‐specific survival (DSS) rates were 88% for the surgery group and 58% for the RT group. After PS matching, the 5‐year DSS rates of the two groups were 86% and 58%, respectively. Similarly, the 5‐year overall survival (OS) rates before PS matching were 80% for the surgery group and 36% for the RT group, whereas after PS matching, they were 73% and 36%, respectively. All these differences were statistically significant ( p < 0.0001). A multivariable analysis identified treatment with RT, older age, stage II tumors, and a higher burden of comorbidities as independent risk factors for both DSS and OS. We also examined the 5‐year outcomes for various subgroups (margin ≥5 mm, margin <5 mm, positive margins, RT combined with chemotherapy, and RT alone) as follows: DSS, 89%/88%/79%/63%/51%, respectively, p < 0.0001; OS, 82%/79%/68%/39%/32%, respectively, p < 0.0001. Conclusions In Taiwanese patients with cT1−2N0M0 OCSCC, a remarkably low proportion (1.1%) completed definitive RT. A significant survival disparity of 30% was observed between patients who underwent initial surgery and those who received definitive RT. Interestingly, even patients from the surgical group with positive surgical margins exhibited a significantly superior survival compared to those in the definitive RT group.
