Abstract:

Objective To explore the expression of Excision repair cross-completion 1 in non-small cell lung cancer and to analyze its clinical significance.Methods ERCC1 protein expression was detected by IHC method in 160 cases of non-small cell lung cancer tissue.We analyzed relationship between the ERCC1 expression and clinicopathological parameters of non-small cell lung cancer,as well as its correlation between ERCC1 expression and the prognosis.At the same time,160 cases of intraoperative specimens were primarily cultured.The relationship between ERCC1 expression and the drug sensitivity of DDP was analyzed.Results ERCC1 protein was mainly expressed in the nucleus.ERCC1 protein expression in lung cancer tissue showed no relationship with age,gender,tumor size and pathological types.ERCC1 protein expression was associated with TNM stages and lymph node metastases.High expression of ERCC1was significantly correlated with poor prognosis in patients,indicating that ERCC1 is the independent factor of NSCLC patients.MTT results showed that the positive expression rate of ERCC1 in DDP sensitive groups was higher than in DDP resistant groups.Conclusion ERCC1 is an independent factor influencing the prognosis of non-small cell lung cancer,and associated with DDP resistance.
