Objective To explore the safer and more reasonable time of withdrawing nucleoside analogues antiviral therapy in women with chronic HBV infection during immune tolerance period. Methods The patients included in this study were 343 pregnant women with chronic HBV infection who received nucleoside antiviral therapy in Obstetrics and Gynecology Center of 302 Military Hospital of China. According to the time of withdrawing antiviral therapy after delivery, the patients were assigned to P0 group, i.e., withdrawal immediately after delivery, and the patients who stopped the drug 6 weeks after delivery were assigned to P6w group. The patients were compared between these two groups in terms of prevalence of ALT abnormality during pregnancy and postpartum, the peak value and occurrence time of postpartum ALT, and mother-to-child vertical transmission. Results The prevalence of postpartum ALT abnormality was 30.2% in P0 group and 20.7% in P6w group (χ2=4.129, P=0.046). Specifically, for the patients with abnormal liver function during pregnancy, the prevalence of postpartum ALT abnormality was 88.0% and 39.4% in the two groups respectively (χ2=14.043, P=0.001). While for the patients with normal liver function during pregnancy, the prevalence of postpartum ALT abnormality was 19.4% and 16.6% respectively (χ2=0.392, P=0.531). Mother-to-infant HBV transmission was blocked successfully in all the patients in spite of the time of withdrawing antiviral therapy. Conclusions For the pregnant women with chronic HBV infection who received oral nucleoside analogue antiviral agents to interrupt motherto-child transmission, the time of withdrawing antiviral agents did not show significant effect on the prevalence of postpartum liver function abnormality and rate of successful blocking mother-toinfant HBV transmission. However, for the patients with abnormal ALT during pregnancy, it is appropriate to continue the nucleoside analogue antiviral therapy after delivery.

Primary liver cancer is a highly malignant tumor of the digestive tract, charac-terized by an insidious onset and frequently accompanied by local progression or distant metastasis. Although surgical resection is typically the optimal treatment for patients with locally resectable tumors, the major challenge in achieving long-term survival prognosis lies in the high postoperative recurrence rate. Due to the substantial heterogeneity and complexity of primary liver cancer, a multimodal comprehensive treatment approach involving surgical resection, systemic therapy ( e.g., targeted therapy, chemotherapy, immunotherapy), and/or local treatment is commonly employed. As research regarding primary liver cancer continues to progress, it becomes crucial for surgical oncologists to acquire a deep understanding and proficiency in the latest surgical diagnostic and treatment methods, along with optimal patient selection and management strategies. The authors aim to comprehensively elaborate on the latest practice guidelines for surgically treatment of primary liver cancer and systematically outline the key points in evaluating primary liver cancer, primarily focusing on hepatocellular carcinoma and intrahepatic bile duct carcinoma, and offer pertinent recommendations for clinical treatment, thus providing robust evidence in the clinical management and decision-making for patients with primary liver cancer.
