Abstract：Objective To investigate the relationship between serum CXC chemokine ligand 1(CXCL1)and positive regulatory zone zinc finger protein 5(PRDM5)levels and lymph node metastasis of progressive gastric cancer and to analyze their predictive value for patients'prognosis.Methods 203 patients with progressive gastric cancer diagnosed in our hospital from June 2020 to March 2023 were selected and divided into the lymph node metastasis group(n=90)and the no-lymph node metastasis group(n=113)based on the presence or absence of lymph node metastasis,and the differences in the general information of the two groups were analyzed and compared,and the diagnostic value of CXCL1 and PRDM5 in lymph node metastasis of progressive gastric cancer was analyzed by plotting the ROC curve.Logistic regression was used to analyze the risk factors of lymph node metastasis in patients with progressive gastric cancer.Follow up for 2 years,draw Kapan Meier curves to compare the prognosis of patients with advanced gastric cancer lymph node metastasis at different levels of CXCL1 and PRDM5.Results The CXCL1 level in the lymph node metastasis group was higher than that in the no-lymph node metastasis group,and its PRDM5 level was lower than that in the no-lymph node metastasis group(P<0.05).The AUCs for diagnosing lymph node metastasis of progressed gastric cancer were 0.755 and 0.844 for CXCL1 and PRDM5,respectively,and the AUC for the combination of the two was 0.898(95%CI 0.848～0.936).The sensitivity and specificity were 88.89%and 77.88%,respectively(P<0.05).Tumor size,differentation degree,serum CEA,serum CA19-9,CXCL1,and PRDM5 levels were all risk factors for lymph node metastasis in patients with progressive gastric cancer(P<0.05).The survival time of patients with CXCL1>96.13 pg/mL is(15.13±0.85)months,while the survival time of patients with CXCL1≤96.13 pg/mL is(19.06±0.66)months.The survival time of patients with CXCL1≤96.13 pg/mL is longer than that of patients with CXCL1>96.13 pg/mL(P<0.05).The survival time of patients with PRDM>100.85 pg/mL is(18.62±0.69)months,while the survival time of patients with PRDM≤100.85 pg/mL is(14.60±0.78)months.The survival time of patients with PRDM>100.85 pg/mL is longer than that of patients with PRDM≤100.85 pg/mL(P<0.05).Conclusion The abnormal expression of CXCL1 and PRDM5 is related to lymph node metastasis in patients with progressive gastric cancer,and the combined detection of the two is of high value in the assessment of lymph node metastasis and prognosis in patients with progressive gastric cancer.
