V1.five in non-metastatic colon cancer and its associations with estrogen receptor (ER)- expression and clinical outcomesJianhong Peng1, Qingjian Ou1,two, Xiaojun Wu1, Rongxin Zhang1, Qian Zhao3, Wu Jiang1, Zhenhai Lu1, Desen Wan1, Zhizhong Pan1* and Yujing Fang1,2*Abstract Background: Voltage-gated sodium channel 1.five (Nav1.5) potentially promotes the migratory and invasive behaviors of colon cancer cells. Hitherto, the prognostic significance of Nav1.5 expression remains undetermined. The present study aimed to explore the associations of Nav1.five expression with clinical outcomes and estrogen receptor- (ER-) expression in non-metastatic colon cancer patients getting radical resection. Approaches: A total of 269 consecutive individuals with pathologically confirmed stages I II colon cancer who underwent radical resection had been selected. Nav1.5 and ER- expression was detected by using immunohistochemistry (IHC) on tissue microarray constructed from paraffin-embedded specimens. IHC score was determined in line with the percentage and intensity of positively stained cells. Statistical analysis was performed using the X-tile system, k coefficient, Chi square test or Fisher’s exact test, logistic regression, log-rank test, and Cox proportional hazards models. Results: We identified that Nav1.five was usually expressed in tumor tissues with higher imply IHC score as compared with matched tumor-adjacent standard tissues (5.1 3.five vs. 3.five two.7, P 0.001). The higher expression of Nav1.five in colon cancer tissues was related with higher preoperative carcinoembryonic antigen level [odds ratio (OR) = 2.980; 95 confidential interval (CI) 1.163.632; P = 0.023] and higher ER- expression (OR = 2.808; 95 CI 1.243.343; P = 0.013). Log-rank test outcomes showed that high Nav1.5 expression contributed to a low 5-year disease-free survival (DFS) rate in colon cancer individuals (77.two vs. 92.BuyIndole-2-carbaldehyde 1 , P = 0.101623-68-1 Chemical name 048), specifically in patients with higher ER- expression tumor (76.PMID:32695810 two vs. 91.three , P = 0.032). Evaluation with Cox proportional hazards model demonstrated that higher Nav1.five expression [hazard ratio (HR) = two.738; 95 CI 1.100.819; P = 0.030] and lymph node metastasis (HR = 2.633; 95 CI 1.6324.248; P 0.001) were prognostic components for unfavorable DFS in colon cancer individuals. Conclusions: Higher expression of Nav1.5 was linked with higher expression of ER- and indicated unfavorable oncologic prognosis in sufferers with non-metastatic colon cancer.
