Abstract:

Objective To investigate the expression and clinical significance of Claudin-6 (CLDN6), tripartite motif-containing protein 59 (TRIM59) and chemokine-like factor-like MARVEL transmembrane domain containing member 6 (CMTM6) in nasopharyngeal carcinoma (NPC) tissue. Methods A total of 135 NPC patients were selected as the study objects, and cancer tissue (observation group) and para-cancer tissue (control group) of all patients were collected. All patients were followed up for 3 years. According to the follow-up results, 93 surviving patients were included in the survival group and 42 dead patients were included in the death group. The mRNA expressions of CLDN6, TRIM59 and CMTM6 were determined by fluorescence quantitative PCR. Multivariate Cox regression was used to analyze the influencing factors of death in NPC patients. Kaplan-Meier method was used to analyze the relationship between the expression levels of CLDN6, TRIM59, CMTM6 and the prognosis of NPC patients. Results Compared with the control group, mRNA expressions of CLDN6, TRIM59 and CMTM6 were increased in the observation group (P<0.05). There were no significant differences in age, sex, body mass index, TNM stage, bone metastasis, smoking history, drinking history and hypertension history between the survival group and the death group. Compared with the survival group, the proportion of NPC family history and the mRNA expression of CLDN6, TRIM59 and CMTM6 in cancer tissue were increased in the death group (P < 0.05). Multivariate Cox regression analysis showed that the increased levels of CLDN6, TRIM59 and CMTM6 in cancer tissue were influential factors for death of NPC patients (P<0.05). According to the mean expression levels of CLDN6, TRIM59 and CMTM6 mRNA in cancer tissue, patients were divided into the low expression group and the high expression group. The 3-year survival rate of the high expression group was significantly lower than that of the low expression group (P<0.05). Conclusion The mRNA expressions of CLDN6, TRIM59 and CMTM6 in NPC tissue are significantly increased, which is a risk factor for death in NPC patients, and the mRNA expressions of CLDN6, TRIM59 and CMTM6 are correlated with the prognosis of patients.
