Abstract:

Objective To investigate the predictive value of dynamic changes in serum prealbumin (PAB) in the treatment of malignant obstructive jaundice (MOJ) with the first endoscopic retrograde cholangiopancreatography (ERCP) biliary stenting. Methods The clinical data of 119 patients with MOJ who were relieved by ERCP stenting for the first time were retrospectively analyzed. Patients were divided into the survival group and the death group according to whether their survival period was greater than 1 year. The liver function indexes of patients before and 7 days after surgery were collected, and the dynamic change rate of PAB (7 d after surgery/preoperative) was calculated. The receiver operating characteristic (ROC) curve was used to determine the best cut-off value of the dynamic change rate of PAB. Patients were divided into two groups according to the cut-off value. The survival curves of the two groups were plotted by K-M method, and risk factors affecting the long-term survival prognosis of patients were analyzed by the Cox proportional hazard model. Results The 1-year survival rate of 119 patients was 45.4% (54/119) and the case fatality rate was 54.6% (65/119). The dynamic rate of PAB was 1.1 (0.9, 1.4) in the survival group, and 0.9 (0.7, 1.0) in the death group, which was significantly higher in the survival group than that in the death group (P<0.05). ROC analysis showed that the area under the ROC curve was 0.799(95% CI:0.704-0.895)and the optimal cut-off value of PAB dynamic rate was 1.008, and the survival analysis showed that the one-year survival rate of the group with high PAB dynamic rate was significantly higher than that in the group with low PAB dynamic rate (P<0.01). Multivariate analysis showed that low dynamic rate of PAB was an independent risk factor for long-term survival of patients with MOJ after ERCP. Conclusion The dynamic rate of PAB can be used as a potential prognostic indicator for MOJ patients.
