Abstract: Oral squamous cell carcinoma (OSCC) affects a substantial proportion of the Asian population and is influenced by various genetic risk factors.The RAR-related orphan receptor beta (RORB), a regulator of the circadian rhythm, has been implicated in certain neoplasms.Accordingly, this study investigated the association between RORB single-nucleotide polymorphisms and clinical manifestations of OSCC.A total of 1174 male patients without OSCC and 1254 male patients with OSCC were included in the study.Three RORB single-nucleotide polymorphism loci-rs3750420 (T/C), rs10781247 (A/G), and rs17611535 (C/T)-were genotyped using TaqMan allelic discrimination assays.RORB single-nucleotide polymorphism rs10781247 variants were significantly associated with moderate to poor cellular differentiation in patients with OSCC (p = 0.042).Additionally, among betel quid chewers with OSCC, rs10781247 variants were significantly associated with moderate to poor cell differentiation (p = 0.036).The rs3750420 variants were significantly associated with larger tumor size in individuals with buccal mucosa cancer (p = 0.036).An analysis of Cancer Genome Atlas data revealed that RORB mRNA levels were significantly higher in patients with head and neck squamous cell carcinoma compared with controls (p = 0.0002).Moreover, RORB mRNA levels were significantly higher in stage IV tumors than in stage III tumors (p = 0.0252).In conclusion, RORB single-nucleotide polymorphisms rs3750420 and rs10781247 are associated with adverse clinical characteristics in OSCC.
