摘要:

目的 探讨非小细胞肺癌(NSCLC)患者癌组织miR-944和膜相关锌指蛋白7(MARCH7) mRNA表达与临床病理特征和预后的关系。 方法 选取2019年7月—2020年7月溧阳市人民医院NSCLC患者97例,收集所有患者临床资料和术中切除的癌组织、癌旁组织(距肿瘤切缘≥2 cm),检测miR-944、MARCH7 mRNA相对表达量。对所有患者进行3年随访。采用Kaplan-Meier生存曲线分析所有患者的生存情况。采用Cox回归分析评估NSCLC患者预后影响因素。 结果 NSCLC患者癌组织miR-944、MARCH7 mRNA相对表达量显著高于癌旁组织(P<0.05)。TNM分期Ⅲa期、有淋巴转移、组织低分化的NSCLC患者miR-944、MARCH7 mRNA相对表达量分别高于TNM分期Ⅰ~Ⅱ期、无淋巴转移、组织中高分化的NSCLC患者(P<0.05)。癌组织miR-944、MARCH7 mRNA判断NSCLC患者死亡的最佳临界值分别为2.39、3.05,根据最佳临界值将NSCLC患者分别分为miR-944、MARCH7 mRNA高表达组和低表达组。miR-944高表达组3年总生存率[27.03%(10/37)]低于miR-944低表达组[48.15%(26/54)](Log-rank χ2=5.901,P=0.015);MARCH7 mRNA高表达组3年总生存率[28.13%(9/32)]低于MARCH7 mRNA低表达组[45.76%(27/59)](Log-rank χ2=9.998,P=0.002)。有淋巴转移、TNM分期Ⅲa期、组织低分化、miR-944高表达、MARCH7 mRNA高表达是NSCLC患者死亡的危险因素(P<0.05)。 结论 NSCLC患者癌组织miR-944、MARCH7 mRNA均呈高表达,且与病情严重程度和预后密切相关,或可作为NSCLC患者预后评估的指标。

Abstract:

Objective To investigate the relationship between the expression of miR-944 and membrane-associated ring finger protein 7(MARCH7) mRNA in cancer tissues of non-small cell lung cancer(NSCLC) patients and their clinical pathological characteristics and prognosis. Methods A total of 97 NSCLC patients from Liyang People's Hospital from July 2019 to July 2020 were enrolled. All patients' clinical data were collected,and cancer tissues and adjacent tissues(≥2 cm from tumor margin) were collected during surgery. The relative expression levels of miR-944 and MARCH7 mRNA were determined. All the patients were followed up for 3 years. The survival of all the patients was analyzed using Kaplan-Meier survival curve. Cox regression analysis was used to evaluate the factors affecting the prognosis of NSCLC patients. Results The relative expression levels of miR-944 and MARCH7 mRNA in cancer tissues of NSCLC patients were higher than those in adjacent tissues(P<0.05). The relative expression levels of miR-944 and MARCH7 mRNA in NSCLC patients with TNM stage Ⅲa,lymphatic metastasis and low differentiation were higher than those in NSCLC patients with TNM stage Ⅰ-Ⅱ,no lymphatic metastasis and moderate to high differentiation(P<0.05). The optimal cut-off values of miR-944 and MARCH7 mRNA in cancer tissues for predicting NSCLC patient death were 2.39 and 3.05,respectively. NSCLC patients were classified into miR-944 and MARCH7 mRNA high-expression and low-expression groups based on the optimal cut-off values. The 3-year overall survival rate of miR-944 high-expression group [27.03%(10/37)] was lower than that of miR-944 low-expression group [48.15%(26/54)](Log-rank χ2=5.901,P=0.015). The 3-year overall survival rate of MARCH7 mRNA high-expression group [28.13%(9/32)] was lower than that of MARCH7 mRNA low-expression group [45.76%(27/59)](Log-rank χ2=9.998,P=0.002). Lymphatic metastasis,TNM stage Ⅲa,low differentiation,high miR-944 expression and high MARCH7 mRNA expression were risk factors for NSCLC patient death(P<0.05). Conclusions The miR-944 and MARCH7 mRNA are highly expressed in NSCLC cancer tissues and are related to the severity of disease and prognosis. They may be used as indicators for prognosis assessment in NSCLC patients.
