OBJECTIVE: Vitamin D has been demonstrated to play a protective role in carcinogenesis. Polymorphisms of the vitamin D receptor (VDR) genes and 24-α-hydroxylase (encoded by CYP24A1) may affect the outcome of some cancers. This study examines the effects of the VDR gene and CYP24A1 single nucleotide polymorphisms on the outcome of supraglottic larynx cancer.
PATIENTS AND METHODS: Patients diagnosed with supraglottic larynx cancer between 2017 and 2022 were enrolled. Single nucleotide polymorphisms of the VDR gene (rs2228570, rs731236, rs7975232, rs11574113, rs11168267 and rs11168266) and CYP24A1 gene (rs4809960, rs6022999, rs6068816, rs2259735 and rs2296241) were investigated. All patients were followed up for any evidence of local recurrence, regional recurrence, distant metastasis, and second primary tumor development. Cox regression analysis was performed to evaluate the prognostic value of single-nucleotide polymorphisms (SNPs). Kaplan-Meier method was used for survival analysis.
RESULTS: 87 patients were included. The mean follow-up time was 45.02±24.47 months. Cox regression analysis for locoregional recurrence revealed that the hazard ratio of rs731236 GG was 2.098 (95% CI, range: 1.047-4.202, p=0.037). Locoregional recurrence for rs731236 AA, AG, and GG were 38.6%, 23.1%, and 53.3%, respectively. In the presence of rs731236 GG polymorphism, disease-specific survival was significantly shorter (47.63±7.48 months, p=0.015), and disease-free survival (45.71±6.3 months) was significantly shorter (p=0.040). Rates of metastases and second primary tumors were not significantly different between SNPs.
CONCLUSIONS: This study has demonstrated the possible effects of VDR rs731236 SNP on the locoregional recurrence and prognosis of supraglottic larynx cancer.
