Abstract:
Objective To investigate the risk factors for myocardial injury after Nano-Knife surgery in patients with pancreatic cancer, and to establish a nomogram model for risk prediction. Methods A retrospective analysis was performed for the clinical data of 92 patients with pancreatic cancer who underwent Nano-Knife surgery in The Fifth Affiliated Hospital of Zhengzhou University from September 2020 to November 2021, with serum cardiac troponin I > 0.03 ng/mL within 3 days after surgery as the diagnostic criteria for myocardial injury, the patients were divided into myocardial injury group with 51 patients and non-myocardial injury group with 41 patients. Related baseline data were collected for all patients, including age, sex, body mass index, American Society of Anesthesiologists classification, smoking history, alcohol abuse history, and preoperative comorbidities. The Mann-Whitney U test was used for comparison of continuous data between groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Univariate and multivariate logistic regression analyses were used to screen out the variables with statistical significance, and the factors screened out were used to establish a nomogram for predicting the risk of myocardial injury after Nano-Knife surgery in patients with pancreatic cancer. The receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) were used to evaluate the discriminatory ability and clinical utility of the model. Results Compared with the non-myocardial injury group, the myocardial injury group had a significantly longer ablation time ( χ 2 =7.410, P =0.006), a significantly greater number of probes ( χ 2 =6.130, P =0.047), and a significantly higher proportion of patients with preoperative hypertension ( χ 2 =12.124, P < 0.001) or chronic kidney disease ( χ 2 =12.829, P < 0.001). The univariate logistic regression analysis showed that tumor diameter, ablation time, surgical procedure, number of probes, history of hypertension, and history of chronic kidney disease were associated with the development of myocardial injury (all P < 0.05), and the multivariate logistic regression analysis showed that tumor diameter (odds ratio [ OR ]= 3.94, 95% confidence interval [ CI ]: 1.09-14.18, P =0.036), ablation time ( OR =4.15, 95% CI : 1.30-13.27, P =0.016), surgical procedure ( OR =6.92, 95% CI : 1.92-25.07, P =0.003), and history of hypertension ( OR =4.07, 95%CI: 1.12-14.77, P =0.034) were independent risk factors for myocardial injury after Nano-Knife surgery in patients with pancreatic cancer. An AUC of 0.859 showed that the nomogram had good discriminatory ability and clinical utility. Conclusion There is a relatively high incidence rate of myocardial injury after Nano-Knife surgery in patients with pancreatic cancer. Preoperative hypertension, tumor diameter > 4 cm, and ablation time > 1 hour are independent risk factors for myocardial injury, and the surgical procedure of Nano-Knife surgery and bypass anastomosis can increase the risk of myocardial injury. The nomogram has a good effect in predicting the risk of myocardial injury.
