Abstract:

Objective To investigate the influence of the expression profile characteristics of apolipoprotein (APO) and interleukin enhancer binding factor (ILF) on the surgical prognosis in patients with locally advanced gastric cancer. Methods A total of 186 patients with locally advanced gastric cancer who received neoadjuvant chemotherapy (NACT) combined with radical gastrectomy at Karamay Central Hospital of Xinjiang from February 2021 to February 2023 were selected as the research subjects. All patients were followed up for at least 2 years to analyze postoperative survival and tumor progression within 2 years. Differences in general clinical data,tumor pathological features,NACT and surgical characteristics,serum APO level before NACT,and ILF expression in tumor tissues before NACT were compared between patients with poor and good prognosis. Multivariate logistic regression analysis was used to identify influencing factors for surgical prognosis in patients with locally advanced gastric cancer. Receiver operator characteristic (ROC) curve was used to evaluate the efficacy of combined factors in predicting surgical prognosis in patients with locally advanced gastric cancer. Results Within 2 years after surgery,103 patients had tumor recurrence,42 had metastasis,and 62 had related death in 186 patients with locally advanced gastric cancer,with an overall poor prognosis rate of 65.05% (121/186). The ages of patients with poor and good prognosis were 63 (60,66) and 62 (58,64) years,respectively,with a statistically significant difference (Z=2.14,P=0.032). The maximum tumor diameter was 5.2 (4.5,5.9) cm in patients with poor prognosis and 4.9 (3.8,5.8) cm in patients with good prognosis,with a statistically significant difference (Z=2.28,P=0.023). There were statistically significant differences in differentiation degree (χ²=5.47,P=0.019),T stage (χ²=5.41,P=0.020),and N stage (χ²=5.18,P=0.023). There was a statistically significant difference in NACT efficacy between patients with poor and good prognosis (χ²=6.11,P=0.013). The number of lymph nodes dissection was 21 (20,22) in patients with poor prognosis and 21 (20,23) in patients with good prognosis,with a statistically significant difference (Z=2.23,P=0.025). The APOA1 levels before NACT were (893.24±178.12) and (977.13±258.07) mg/L,the APOB levels were (982.00±201.21) and (910.64±153.06) mg/L,the APOC1 levels were (92.88±18.12) and (84.14±20.09) mg/L,and the APOD levels were (76.62±15.89) and (71.34±14.42) mg/L in patients with poor and good prognosis,respectively,all with statistically significant differences (t=2.61,P=0.010; t=2.50,P=0.013; t=3.02,P=0.003; t=2.23,P=0.027). There were statistically significant differences in the expression of ILF1 and ILF2 in tumor tissues between patients with poor and good prognosis (χ²=6.62,P=0.010; χ²=5.07,P=0.024). Multivariate analysis showed that,T stage (OR=2.94,95%CI: 1.23-7.01,P=0.015),N stage (OR=2.67,95%CI: 1.14-6.24,P=0.023),NACT efficacy (OR=1.50,95%CI: 1.18-3.33,P=0.026),number of lymph nodes dissection (OR=0.75,95%CI: 0.58-0.96,P=0.024),APOA1 (OR=0.99,95%CI: 0.98-0.99,P=0.042),APOB (OR=1.03,95%CI: 1.00-1.05,P=0.028),APOC1 (OR=1.10,95%CI: 1.01-1.21,P=0.040),ILF1 (OR=2.28,95%CI: 1.04-5.02,P=0.041),and ILF2 (OR=1.86,95%CI: 1.26-3.01,P=0.032) were all independent factors influencing surgical prognosis in patients with locally advanced gastric cancer. The ROC curve analysis showed that,the area under the curve of the combined prediction of the above influencing factors for surgical prognosis in patients with locally advanced gastric cancer was 0.79 (95%CI: 0.72-0.86). Conclusions APO levels and ILF expression characteristics in tumor tissues are independent influencing factors for surgical prognosis in patients with locally advanced gastric cancer. Combined detection of T stage,N stage,NACT efficacy,number of lymph nodes dissection,APOA1,APOB,APOC1,ILF1,and ILF2 has high predictive efficacy for the surgical prognosis of patients with locally advanced gastric cancer.
