Value of spiral CT multi-parameter combined preoperative evaluation of microvascular invasion in small liver cancer

Objective: To explore the value of multi-slice spiral CT (MSCT) in predicting microvascular invasion in hepatocellular carcinoma (HCC). Methods: The CT and clinical data of 102 patients with HCC were collected for retrospective analysis from January 2018 to December 2020 at Baoji Center Hospital, China. They were divided into two groups based on the pathological results with or without microvascular invasion. The independent sample t-test was used to compare the age, alpha-fetoprotein (AFP) value, tumor size, and tumor enhancement of the two groups. CT value; χ2 test was used to compare gender, hepatitis type, liver function classification, degree of classification, degree of tumor smoothness, envelope, peripheral enhancement, etc. between the two groups. Results: There were 52 cases of non-microvascular invasion and 50 cases of microvascular invasion. The tumor size, grade, degree of margin, capsule, portal vein CT value, and peripheral enhancement were related to microvascular invasion. Conclusion: Microvascular invasion of HCC can be predicted by MSCT manifestations before surgery. doi: https://doi.org/10.12669/pjms.37.6-WIT.4851 How to cite this:Li K, Peng Y, Tian H, He H.

Effect of Percutaneous Radiofrequency Ablation and Surgical Resection on Treating of Primary Small Liver Cancer: A Meta-Analysis

Objective: To analyze the clinical effect of primary small liver cancer under radiofrequency ablation (RFA) and surgical resection (SR) treatment, and to explore the best application timing of the two treatment methods. Methods: Randomly controlled clinical trials (RCT) of percutaneous radiofrequency ablation and surgical resection for the treatment of small liver cancer in various databases were searched according to the established search strategy, and Meta data was analyzed based on RevMan5.3 software provided by Cochrane collaborative organization. Results: A total of 10 articles were included in this study, including 1396 patients, 699 in the RFA group and 697 in the SR group. Meta-analysis results showed that the two groups had no statistical difference in overall survival rate at 1 and 3 years, 1-year disease-free survival rate, and 1-year recurrence rate (P>0.05). The 3-year disease-free survival rate of the RFA group was lower than that of the SR group, and the 3-year recurrence rate was higher than that of the SR group. The higher postoperative complication rate tended to the SR group, and the differences were statistically significant. (P<0.05). Conclusion: For short-term efficacy, radiofrequency ablation and surgical resection show consistency; for long-term efficacy, surgical resection is more effective.
