Abstract:
Objective To investigate the expression levels of micro RNA-651(miR-651)and the transcrip-tion factor Forkhead Box N2(FOXN2)in lung cancer tissues and to analyse their relationship with patients' prognosis after lobectomy.Methods A total of 98 patients with lung cancer who underwent lobectomy from January 2020 to December 2021 in Nantong Cancer Hospital were selected as research objects,the lung cancer tissue specimens and corresponding paracancerous tissue specimens of patients were collected,the expression levels of miR-651 and FOXN2 were detected by real-time fluorescence quantitative PCR(qPCR),and their re-lationship with the prognosis of patients after lobectomy was analyzed.Results At 2-year follow-up,19(19.39%)of 98 patients had recurrent metastasis,and the median time to recurrent metastasis was 20 months(95%CI:18.626--21.374).qPCR assay showed that the expression levels of miR-651 and FOXN2 in lung cancer tissues were significantly lower than those in paracancerous tissues(P<0.05).miR-651 and FOXN2 expression levels were significantly correlated with clinicopathological features such as tumour size,TNM stage and lymph node metastasis(P<0.05).The results of univariate Cox regression analysis showed that the percentages of maximum tumor diameter ≥3 cm,TNM stage Ⅱ,lymph node metastasis,miR-651 low ex-pression and FOXN2 low expression were higher in the poor prognosis group than those in the good prognosis group(P<0.05).Multifactorial Cox regression analysis showed that maximum tumor diameter ≥ 3 cm(HR=3.185,95%CI:1.105-9.182),TNM stage Ⅱ(HR=5.167,95%CI:1.939-13.771),lymph node metastasis(HR=2.860,95%CI:1.115-7.338),low miR-651 expression(HR=5.345,95%CI:1.845-15.483)and low FOXN2 expression(HR=5.404,95%CI:1.744-16.745)were independent risk factors for the prognosis of lung cancer patients after lobectomy(P<0.05).Conclusion The expression levels of miR-651 and FOXN2 were reduced in the tissues of lung cancer patients,and both were associated with tumour size,TNM stage,lymph node metastasis,and patients' prognosis after lobectomy.
