ABSTRACT
Objective:To investigate the factors affecting prognosis of pancreatic cancer patients with carbohydrate antigen 19-9 (CA19-9) negative before surgery.Methods:Retrospectively analyzed the clinic pathological data of 158 patients with pancreatic cancer who underwent radical surgery between November 2011 and August 2022, including 84 males, and 74 females, aged (65±9) years old. Patients were divided into two groups according to CA 19-9 levels over a threshold of 37 U/ml. Patients with CA19-9 levels ≤37 U/ml were included in the CA19-9 negative group ( n=34), while patients with CA19-9 levels >37 U/ml were included in the CA19-9 positive group ( n=124). We performed a comparison between the two groups regarding demographic and clinical data, tumor staging, lymphovascular and nerve invasion and so on. Survival data were extracted from outpatient or telephone records during follow-up. The Kaplan-Meier method was used to draw the survival curve, and the survival rate was compared by log-rank test. Multivariate analysis was performed using the Cox regression analysis model. Results:CA19-9 expression was associated with tumor location and nerve invasion (both P<0.001). There was no significant difference in cumulative survival rate ( χ2=0.07, P=0.787) and progression-free survival rate ( χ2=0.13, P=0.721) between two groups. Multivariate analysis showed that lymphovascular invasion ( HR=5.962, 95% CI: 2.189-16.239, P<0.001) was a prognostic factor for overall survival in the CA19-9 negative group. Age ≤60 years old ( HR=0.306, 95% CI: 0.118-0.796, P=0.015) and lymphovascular invasion ( HR=3.096, 95% CI: 1.232-7.780, P=0.016) were prognostic factors for progression-free survival. Conclusion:Age ≤60 years old and lymphovascular invasion are the influencing factors of poor prognosis in pancreatic cancer patients with CA19-9 negative.
