Head and neck cancer is the seventh leading cancer diagnosis worldwide. One of the most common cancers in the head and neck region is laryngeal cancer. In past years, the incidence of laryngeal squamous cell carcinoma has risen by 23%, and despite progress in treatment modalities, the survival rate has not changed. It is well known that genetic alterations may contribute to individuals' susceptibility to cancer. Research of genetic alterations, such as single nucleotide polymorphisms, is essential to understanding carcinogenesis and susceptibility of laryngeal squamous cell carcinoma. A total of 200 LSCC patients and 200 controls were included in this retrospective case-control study; both groups were matched by age and sex. In the present study, we analyzed six SNPs in genes essential for apoptosis regulation: (rs9895829, rs17884306), (rs1564483, rs4987855), (rs704243), () (rs1041978, rs78800940). We evaluated their associations with the risk of LSCC development, its pathomorphological manifestation, and patients' overall survival rate. Genotyping was carried out using RT-PCR. The AG genotype of rs9895829 was more prevalent in controls than in cancer patients, leading to lower susceptibility to LSCC (OR = 0.301; 95%CI 0.096-0.940; = 0.039). None of the analyzed SNPs showed an association with pathomorphological features of LSCC, but rs1041978 T allele carriers were found to be diagnosed with LSCC at an older age (OR = 1.962; 95%CI 1.072-3.592; = 0.031). There was no statistically significant association between investigated SNPs and patient OS. The present study indicates that the AG genotype of rs9895829 provides a protective effect against LSCC development.
头颈部癌是全球第七大常见癌症诊断。头颈部区域最常见的癌症之一是喉癌。近年来,喉鳞癌的发病率上升了 23%,尽管治疗方式有所进展,但生存率没有改变。众所周知,遗传改变可能导致个体易患癌症。研究遗传改变,如单核苷酸多态性,对于理解喉鳞癌的致癌作用和易感性至关重要。本回顾性病例对照研究共纳入 200 例喉癌患者和 200 例对照者,两组按年龄和性别匹配。在本研究中,我们分析了凋亡调控相关基因中的 6 个 SNP:(rs9895829,rs17884306),(rs1564483,rs4987855),(rs704243),(rs1041978,rs78800940)。我们评估了它们与 LSCC 发病风险、其病理形态表现以及患者总生存率的关系。采用 RT-PCR 进行基因分型。与癌症患者相比,rs9895829 的 AG 基因型在对照组中更为常见,导致 LSCC 易感性降低(OR = 0.301;95%CI 0.096-0.940; = 0.039)。分析的 SNP 均与 LSCC 的病理形态特征无关,但 rs1041978 T 等位基因携带者的 LSCC 诊断年龄更大(OR = 1.962;95%CI 1.072-3.592; = 0.031)。所研究的 SNP 与患者 OS 之间无统计学显著关联。本研究表明,rs9895829 的 AG 基因型对 LSCC 的发生具有保护作用。
