Abstract:
Objective To investigate the clinical significance of dynamic changes in the expression levels of tumor associated autoantibody(TAAB),including tumor protein 53(p53),protein gene product 9.5(PGP9.5),SRY-box containing gene 2(SOX2),G antigen 7 ATP-dependent RNA helicase(GAGE7),ATP-dependent RNA helicase(GBU4-5),melanoma antigen A1(MAGE A1),cancer/testis antigen(CAGE)in non-small cell lung cancer(NSCLC)patients before and after surgery.Methods Forty-one patients with NSCLC who underwent surgical treatment at the Department of Thoracic Surgery of Li Huili Hospital,Ningbo Medical Center,were selected from January 2019 to August 2022.Enzyme linked immunosorbent assay(ELISA)was used to detect the expression levels of seven TAAB markers in the serum of 41 NSCLC patients undergoing surgical treatment.Results The expression levels of PGP9.5 were found to be significantly higher in the squamous cancer group than in the adenocarcinoma group(P<0.05),while the expression levels of GAGE7 were found to be significantly higher in the adenocarcinoma group than in the squamous cancer group(P<0.05).The expression level of GBU4-5 was found to be significantly higher in the squamous carcinoma group than in the adenocarcinoma group at one week after surgery(Z=-2.095,P=0.036).Within the adenocarcinoma group,the expression levels of GBU4-5(P=0.027)and CAGE(P=0.042)were found to be significantly lower at one week after surgery compared with those before surgery.The expression levels of PGP9.5(P=0.004),GAGE7(P<0.001),and GBU4-5(P=0.014)were found to have decreased significantly at six months postoperatively in comparison to their preoperative levels.In the squamous cancer group,no statistically significant differences were observed in the expression levels at one week after surgery.The expression level of SOX2(P=0.011)exhibited a statistically significant decrease at six months postoperatively in comparison to the preoperative levels.Similarly,the expression level of GBU4-5 was found to be significantly decreased at one week postoperatively in comparison to the preoperative levels(P=0.009).The expression levels of PGP9.5(P=0.003),GAGE7(P=0.001),and GBU4-5(P=0.013)were found to have decreased significantly at six months postoperatively.Conclusion Surgical intervention can reduce the expression level of 7 TAABs in NSCLC patients.Monitoring 7 TAABs before and after surgical treatment is helpful to predict the surgical efficacy and postoperative disease progression of NSCLC patients.
