Splanchnic neurolysis is a new treatment option. However, not all patients receiving splanchnic neurolysis treatment will achieve satisfactory results. The aim of this study is to retrospectively analyze the predictive value of preoperative serum immune indicators (white blood cells, neutrophils, lymphocytes, and platelets) for the efficacy of splanchnic neurolysis.Methods: The abdominal cancer patients (pancreatic cancer, liver cancer, gastric cancer, colorectal cancer, cholangiocarcinoma, and renal cancer) admitted to the Department of Pain Medicine, Harbin Medical University Cancer Hospital from January 2017 to October 2020 were collected. We evaluate the efficacy of splanchnic neurolysis by assessing the dosage of opioids and Numerical Rating Scale (NRS) scores of patients 24 to 48 hr before and after splanchnic neurolysis. The predictive value of preoperative serum immune indicators on the efficacy of splanchnic neurolysis was analyzed using Receiver Operating Characteristic (ROC). Contract the Nomogram prediction model by R software.Results: We found that Mean Platelet Volume (MPV) has statistical significance for predicting splanchnic neurolysis efficacy in digestive system tumors. MPV and Neutrophil–Lymphocyte Ratio (NLR) are independent predictors and have statistical significance in predicting splanchnic neurolysis efficacy in pancreatic cancer. The combination of MPV and NLR had satisfactory predictive value in pancreatic cancer (AUC = 0.715) and the nomogram model was constructed. Furthermore, there was a negative correlation between lymphocyte count and NRS score, and a positive correlation between Platelet–Lymphocyte Ratio (PLR) and NRS score.Discussion: The combined detection of MPV and NLR has important clinical predictive value for the postoperative efficacy of splanchnic neurolysis in pancreatic cancer.Kewwords: neutrophil–lymphocyte ratio, pancreatic cancer, splanchnic neurolysis, efficacy, nomogram
