Objective: The present study aimed to identify the risk factors for early postoperative recurrence of hepatocellular carcinoma (HCC) in patients with microvascular invasion (MVI) and develop a predictive model.
Inclusion Population And Methods: Patients who underwent surgery for HCC with pathological identification of MVI at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2014 to June 2019 were consecutively enrolled in this study. A total of 416 patients were included, divided into an early recurrence group (N = 169) and a non-early recurrence group (N = 247), taking 12 months as the cut-off point for early recurrence. Univariate and multivariate Cox analysis was adopted to screen for risk factors for recurrence, and independence of risk factors was determined by logistic regression analysis. All variables were included in the logistic regression analysis. As previous studies have shown that tumor diameter is a risk factor for recurrence, this was also included in the analyses. A predictive model for early recurrence was established and evaluated.
Results: The results indicate that MVI grouping, preoperative serum AFP, number of tumors, satellite nodules, hepatic capsule invasion, tumor diameter, and lymph node metastasis are independent risk factors for early postoperative recurrence. The above factors were adopted to develop a predictive model. The model had good discrimination and calibration in predicting early postoperative recurrence. Decision curve analysis demonstrated good clinical utility.
Conclusion: MVI grouping, preoperative serum AFP, number of tumors, satellite nodules, hepatic capsule invasion, tumor diameter, and lymph node metastasis were shown to be independent risk factors for early postoperative recurrence. The predictive model developed by applying the above risk factors had good predictive value in patients with early postoperative recurrence.

Background: Early anal canal cancer is frequently treated with endoscopic submucosal dissection (ESD) to preserve anal function. However, if the lesion is in the anal canal, then significant difficulties such as bleeding and challenges associated with scope manipulation can arise.
Case Summary: A 70-year-old woman undergoing follow-up after transverse colon cancer surgery was diagnosed with anal canal cancer extending to the dentate line.

Background: This study investigates the feasibility and early outcomes of early myocardial reperfusion in patients with type A aortic dissection (TAAD), evaluating its effectiveness and potential benefits compared to traditional cardioplegic arrest techniques.
Methods: A retrospective analysis was conducted on 168 patients diagnosed with TAAD who underwent surgery at the General Hospital of the Northern Theater Command in China from January 2021 to July 2024. Patients were divided into two groups: early myocardial reperfusion (EMR group, = 66) and cardioplegic arrest (CA group, = 102).
