ABSTRACT
Objective:
To explore the efficacy of precision hepatectomy in the treatment of single hepatocellular carcinoma with microvascular invasion (MVI) of and the risk factors of positive incisal margin after operation.Methods:
The clinical data of 212 patients with single hepatocellular carcinoma with MVI treated in Affiliated Hospital of Panzhihua University from July 2016 to July 2019 were analyzed retrospectively. 152 patients were treated with precision hepatectomy and 60 patients with traditional hepatectomy. According to the pathological results of postoperative liver resection, the patients treated with precision hepatectomy were divided into two groups negative group ( n=129) and positive group ( n=23). The operation-related indexes, postoperative complications and disease-free survival rate of precision hepatectomy and traditional hepatectomy were compared, and the general data of patients with negative and positive liver cutting edge were compared. multivariate analysis of the factors affecting the positive liver cutting edge after operation; to construct a line chart prediction model to predict the positive liver cutting edge after operation, and to evaluate its predictive efficiency. Normally distributed measurement data are represented by mean±standard deviation ( Mean± SD), independent t-test is used for comparison between groups; count data are represented by the number of cases and percentages, and χ2 test is used for comparison between groups.Results:
The operative time, intraoperative blood loss, postoperative hospital stay, positive rate of surgical margin, total incidence of postoperative complications, AFP negative conversion rate 6 months after operation, and 1-year disease-free survival rate of precision hepatectomy were (328.62±38.74) min, (496.83±59.76) mL, (15.28±3.61) d, 15.13% (23/152), 3.95% (6/152), 81.58% (124/152), 67.11% (102/152), respectively. The mean values of traditional hepatectomy were (315.29±40.95) min, (681.46±58.27) mL, (23.87±4.65) d, 28.33% (17/60), 21.67% (13/60), 66.67% (40/60) and 46.67% (28/60), respectively, the difference was statistically significant ( P<0.05). Univariate analysis showed that the positive liver resection margin after precision liver resection was related to the maximum diameter of the tumor, vascular tumor thrombus, TNM staging, BCLC staging, liver cirrhosis, AFP 2 months after surgery, and the distance between the tumor and the resection margin ( OR=3.645, 5.248, 4.285, 4.462, 3.883, 3.964, 3.872; 95% CI 2.875-4.415, 4.426-6.070, 3.271-5.299, 3.354-5.570, 3.062-4.704, 3.248-4.680, 2.987-4.757; P<0.05). Maximum tumor diameter >5 cm, vascular tumor thrombus, TNM stage Ⅲ, BCLC stage C, liver cirrhosis, postoperative AFP ≥20 μg Uniql, the distance between the tumor and the resection margin was <1 mm were the risk factors of positive incisal margin after precision hepatectomy in patients with single liver cancer with MVI( OR=6.685, 8.425, 7.758, 7.854, 7.124, 7.246, 6.926; 95% CI 5.828-7.542, 7.6385-9.212, 6.926-8.590, 7.062-8.646, 6.583-7.665, 6.618-7.874, 6.028-7.824; P<0.05). The constructed line chart prediction model had better differentiation and higher accuracy.Conclusions:
Precision hepatectomy in the treatment of single hepatocellular carcinoma with MVI has the advantages of less intraoperative bleeding, faster postoperative recovery, less postoperative complications, low positive rate of liver incisal margin and high disease-free survival rate. The construction of a risk prediction model with positive surgical margin provides a reference for improving the survival rate of patients in clinic.
