Abstract:
Objective To investigate the expression of activating transcription factor 6(ATF6)and interferon α(IFN-α)and their significance in laryngeal squamous cell carcinoma(LSCC)tissue.Methods A total of 100 LSCC patients admitted to Clinical Medical College of Henan University of Science and Technology/the First Affiliated Hospital of Henan University of Science and Technology from March 2015 to March 2020 were selected,and their clinicopathological features such as tumor location,degree of differentiation,and lymph node metastasis were collected and organized.Immunohistochemical method was applied to detect the expression of ATF6 and IFN-α in tissues.Spearman method was used to analyze the correlation between ATF6 and IFN-α expression in LSCC tissue.Kaplan-Meier method was applied to analyze the relationship between ATF6 and IFN-α expression in LSCC tissue and 3-year survival rate of patients.Cox regression was used to analyze the influencing factors of 3-year mortality in LSCC patients.Results The positive rate of ATF6 in LSCC tissue(76.00%)was higher than that in normal tissues adjacent to cancer(13.00%),the positive rate of IFN-α in LSCC tissue(29.00%)was lower than that in normal tissues adjacent to cancer(74.00%),and the difference was statistically significant(χ2=80.352,40.536,all P<0.05).The proportions of ATF6 positive expression in LSCC patients with TNM stage Ⅲ+Ⅳ,deep infiltration depth,and lymph node metastasis were significantly higher than those in LSCC patients with TNM stage Ⅰ+Ⅱ,shallow infiltration depth,and no lymph node metastasis(χ2=7.310,9.223,5.123,all P＜0.05).The proportions of IFN-α negative expression in LSCC patients with TNM stage Ⅲ+Ⅳ,deep infiltration depth,and lymph node metastasis were significantly higher than those in LSCC patients with TNM stage Ⅰ+Ⅱ,shallow infiltration depth,and no lymph node metastasis(χ2=8.564,5.021,5.203,all P＜0.05).There was a negative correlation between ATF6 and IFN-α expression in LSCC tissues(r=-0.415,P<0.05).The 3-year survival rate of LSCC patients in the ATF6 positive expression group(50.00%)was significantly lower than that in the ATF6 negative expression group(83.33%),while the 3-year survival rate of LSCC patients in the IFN-α positive expression group(82.76%)was significantly higher than that in the IFN-α negative expression group(47.89%)(Log rank χ2=8.002,10.854,all P<0.05).ATF6(HR=1.735,95%CI:1.159～2.598)and IFN-α(HR=0.624,95%CI:0.439～0.886)were influencing factors for the mortality of LSCC patients.Conclusion The positive expression rate of ATF6 increased and the positive expression rate of IFN-α decreased in LSCC tissues.They were closely related to the clinical pathological characteristics and prognosis of patients.
