Objective To explore the correlation between multiple clinicopathologic factors and perineural invasion in patients with pancreatic carcinoma.Methods The clinical data of 90 patients with pancreatic carcinoma in the Department of General Surgery of Shanghai Ninth People’s Hospital of Shanghai JiaoTong University School of Medicine from January 2012 to January 2020 were retrospectively collected. We collected clinical data such as patient medical records, surgical records, nursing records, examination reports, pathological reports, and studied the parameters that affect the occurrence of perineural invasion in patients with pancreatic carcinoma.Results Among 90 patients with pancreatic carcinoma, 47 cases had perineural invasion and 43 cases had no perineural invasion. The univariate analysis results showed that perineural invasion was associated with abdominal pain and low back pain, levels of fasting blood glucose, glycosylated hemoglobin, CA19-9, carcinoembryonic antigen (CEA), and bilirubin, as well as tumor location, TNM stage, differentiation degree, lymph node metastasis, vascular cancer thrombus, peripheral invasion, and expression of p53 (P<0.05). Binary logistic regression analysis showed that abdominal or lower back pain, increased fasting blood glucose, tumor with invasion of surrounding tissues, and p53-positive expression were the independent risk factors for perineural invasion of pancreatic carcinoma (P<0.05).Conclusion Patients with pancreatic carcinoma have abdominal or lower back pain, elevated fasting blood glucose before surgery, tumor with surrounding tissue invasion, and p53-positive expression are independent risk factors for perineural invasion, which should be paid attention to.
