Recently, a systemic therapy for advanced hepatocellular carcinoma (HCC) has been developed. The regimen for unresectable HCC varies and includes single or multi-tyrosine kinase inhibitors, monoclonal antibodies, immune checkpoint inhibitors, or their combinations. Treatment with these agents begins with sorafenib as the first-line drug for unresectable HCC. Subsequently, several systemic therapies, including lenvatinib, ramucirumab, cabozantinib, and regorafenib have been investigated and established. With advances in systemic therapy for unresectable HCC, the prognosis of patients with unresectable HCC has improved significantly than previously. Conversion surgery, consisting of systemic therapy and surgery, showed the possibility of improving the prognosis than systemic therapy alone. Although a combination of atezolizumab and bevacizumab is mostly used for initially unresectable HCC to conduct conversion surgery because of the high response rate and fewer adverse events compared to others, many trials are being conducted to assess their efficacy for initially unresectable HCC. However, the appropriate timing of surgery and interval between systemic therapy and surgery remain controversial. To address these issues, a multidisciplinary team can play a vital role in determining the strategies for treating unresectable HCC. This review describes previous and current trends in the treatment of HCC, with a particular focus on conversion surgery for initially unresectable HCC.

This study aimed at analyzing and comparing the clinical efficacy and prognosis of repeat laparoscopic hepatectomy (r-LH) and radiofrequency ablation (RFA) in treating recurrent hepatocellular carcinoma (RHCC). Clinicopathological data of RHCC patients who underwent r-LH or RFA as treatment from three medical centers were retrospectively reviewed. Baseline characteristics at the recurrence time after initial hepatectomy and clinical outcomes following treatment of RHCC were compared between the two groups. Using the Kaplan-Meier method, survival curves for the two groups of patients were generated, and the log-rank test was used to compare survival differences. Propensity score matching (PSM) analysis was used to match patients of the r-LH and RFA groups in a 1:1 ratio. A total of 272 patients were enrolled, including 133 patients who underwent r-LH and 139 patients who received RFA. After PSM, 76 patients were matched in each study group. Compared with the r-LH group, the RFA group had shorter hospitalization and fewer postoperative complications. However, the r-LH group had significantly better overall survival (OS) and disease-free survival (DFS) than the RFA group before and after PSM. Subgroup analysis demonstrated that RHCC patients with solitary tumor or those with tumors located near the diaphragm, visceral surface or vessels, had survival benefits from r-LH. When tumor diameter ≤ 5 cm, r-LH appears to be an effective priority to RFA with a significantly higher OS and DFS rate in treating RHCC patients, especially for patients with solitary tumor and those with tumors located near the diaphragm, visceral surface or vessels.

The role of laparoscopic liver resection (LLR) for intrahepatic cholangiocarcinoma (ICC) remains debated. This study aimed to evaluate the short- and long-term outcomes of LLR vs. open liver resection (OLR) in ICC stratified by tumor burden score (TBS). ICC patients who underwent LLR or OLR were included from a multicenter database between July 2009 and October 2022. Patients were stratified into two cohorts based on whether the TBS was > 5.3. A 1:3 propensity score matching (PSM) analysis was performed between LLR and OLR in each cohort. Cox regression analysis was used to identify prognostic factors for ICC. A total of 626 patients were included in this study, 304 and 322 patients were classified into the low- and high-TBS groups, respectively. In the low-TBS group, after PSM, LLR was associated with less blood loss, lower CCI, fewer complications and shorter hospital stay (all p < 0.05). Kaplan-Meier curves revealed that LLR had better OS (p = 0.032). Multivariate Cox regression analysis showed that surgical procedure was an independent prognostic factor for ICC (HR: 0.445; 95% CI: 0.235-0.843; p = 0.013). In the high-TBS group, after PSM, LLR were associated with reduced blood loss, lower CCI, fewer complications and shorter hospital stay (all p < 0.05), while OS (p = 0.98) and DFS (p = 0.24) were similar between the two groups. TBS is an important prognostic factor for ICC. LLR is a safe and feasible option for ICC and leads to faster postoperative recovery. LLR can offer ICC a comparable and even better long-term prognosis than OLR.

Biliary tract tumors (BTC) account for about 3% of all digestive system tumors, with rising incidence and limited treatment options, particularly for advanced stages, underscoring the need for innovative therapies. This retrospective cohort study evaluated the safety and efficacy of a novel regimen combining hepatic artery infusion chemotherapy with 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX-HAIC) alongside lenvatinib and programmed cell death protein-1 (PD-1) inhibitors (mFOLFOX-HAIC+lenvatinib+PD-1i) compared to standard regimens of gemcitabine plus cisplatin, gemcitabine plus S1, or gemcitabine plus oxaliplatin (GC/GS/GEMOX) in advanced BTC patients treated from March 2019 to November 2023. A total of 89 patients were analyzed, with 55 receiving hepatic arterial infusion chemotherapy and 34 receiving the GC/GS/GEMOX regimens. Among these, 23 patients were in the mFOLFOX-HAIC+lenvatinib+PD-1i group, while 24 were in the GC/GS/GEMOX group. The median progression-free survival (mPFS) for the mFOLFOX-HAIC+lenvatinib+PD-1i group was 15 months compared to 6 months for the GC/GS/GEMOX group. Similarly, the median overall survival (mOS) was 20 months for the mFOLFOXHAIC+lenvatinib+PD-1i group versus 13 months for the GC/GS/GEMOX group. The objective response rate (ORR) and disease control rate (DCR) for the mFOLFOX-HAIC+lenvatinib+PD-1i group were 48.5% and 87.0%, respectively, both significantly higher than those observed in the GC/GS/GEMOX group at three months of treatment. The incidence of adverse events (AEs) was similar between the mFOLFOX-HAIC+lenvatinib+PD-1i group and the GC/GS/GEMOX group, at 86.5% and 84.2%, respectively, with no statistically significant difference in complication rates. Overall, mFOLFOX-HAIC+lenvatinib+PD-1i appears to be a safe and well-tolerated treatment for advanced BTC, demonstrating superior mPFS and mOS compared to standard regimens.

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits. In order to improve the long-term survival rate of the overall population with liver cancer and achieve the goal of a 15% increase in the overall 5-year survival rate outlined in the Healthy China 2030 blueprint, the Professional Committee for Prevention and Control of Hepatobiliary and Pancreatic Diseases of Chinese Preventive Medicine Association, Chinese Society of Liver Cancer, and the Liver Study Group of Surgery Committee of Beijing Medical Association organized in-depth discussions among relevant domestic experts in the field. These discussions focused on the latest progress since the release of the Chinese expert consensus on conversion therapy of immune checkpoint inhibitors combined antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2021 Edition) and resulted in a new consensus on the modifications and supplements to related key points. This consensus aims to further guide clinical practice, standardize medical care, and promote the development of the discipline.

The prognosis following radical surgery for intrahepatic cholangiocarcinoma (ICC) is poor, and optimal follow-up strategies remain unclear, with ongoing debates regarding anatomic resection (AR) versus non-anatomic resection (NAR). This study included 680 patients from five hospitals, comparing a combination of eight feature screening methods and 11 machine learning algorithms to predict prognosis and construct integrated models. These models were assessed using nested cross-validation and various datasets, benchmarked against TNM stage and performance status. Evaluation metrics such as area under the curve (AUC) were applied. Prognostic models incorporating screened features showed superior performance compared to unselected models, with AR emerging as a key variable. Treatment recommendation models for surgical approaches, including DeepSurv, neural network multitask logistic regression (N-MTLR), and Kernel support vector machine (SVM), indicated that N-MTLR's recommendations were associated with survival benefits. Additionally, some patients identified as suitable for NAR were within groups previously considered for AR. In conclusion, three robust clinical models were developed to predict ICC prognosis and optimize surgical decisions, improving patient outcomes and supporting shared decision-making for patients and surgeons.

The current state of systemic therapy for advanced biliary tract cancer (BTC) has undergone significant changes. Currently, there are no clinical trials directly comparing various first-line systemic therapy regimens to each other, and these trials are unlikely to be conducted in the future. In this systematic review, after various abstracts and full-text articles published from the establishment of the database until October 2024 were searched, we included and analysed phase 3 clinical trials to evaluate the efficacy of different first-line systemic treatment regimens in advanced BTC. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines and a random effects model to pool the overall effects. Finally, seven low-risk-of-bias trials (with all of the trials representing first-line trials) were included. A total of 4033 patients were included in seven first-line trials. In terms of progression-free survival (PFS), network meta-analysis revealed that durvalumab + gemcitabine + cisplatin (GemCis) triple therapy, S-1 + GemCis triple therapy, and pembrolizumab + GemCis triple therapy were superior to GemCis. In terms of overall survival (OS), network meta-analysis revealed that durvalumab + GemCis triple therapy and pembrolizumab + GemCis triple therapy outperformed GemCis. According to the ranking of the P scores, durvalumab + GemCis triple therapy ranked first in PFS and second in OS. Therefore, the advantages of molecular immunotherapy have gradually become known, which suggests that future trials should focus on other potential combinations and molecular immunotargeted therapies.

Water-based therapy has been gaining attention in recent years and is being widely used in clinical settings. Hydrotherapy is the most important area of water-based therapy, and it has distinct advantages and characteristics compared to conventional land-based exercises. Several new techniques and pieces of equipment are currently emerging with advances in computer technologies. However, comprehensive reviews of hydrotherapy are insufficient. Hence, this study reviewed the status quo, mechanisms, adverse events and contraindications, and future prospects of the use of hydrotherapy. This study aims to comprehensively review the latest information regarding the application of hydrotherapy to musculoskeletal diseases, neurological diseases, and COVID-19. We have attempted to provide a "take-home message" regarding the clinical applications and mechanisms of hydrotherapy based on the latest evidence available.

Respiratory infectious diseases have long been a serious public health problem. This study explores the significance of respiratory infectious disease prevention and control systems worldwide, particularly during and after the COVID-19 pandemic. The epidemiology of many respiratory diseases such as influenza changed over the past two years, and the incidence of pathogens such as Mycoplasma pneumoniae and Bordetella pertussis has also increased. Based on influenza surveillance data in China, the influenza season in 2023 was notably delayed and extended, with A(H1N1) pdm09 being the predominant strain. This editorial also reviewed the gradual establishment of China's infectious disease prevention and control system following the 2003 SARS outbreak, highlighting the role of medical facilities in managing public health emergencies, conducting infectious disease pre-screening, and reporting cases to networks in real time. In the future, China will further develop an intelligent, multi-trigger infectious disease surveillance and early warning system to increase the early detection of unknown infectious diseases and optimize the allocation of medical resources. A robust infectious disease control system is crucial to addressing future pandemic threats.

This article was to summarize the clinical features and treatment course in patients with pulmonary cryptococcal infections with different imaging manifestations and to analyse the relevant factors. Categorical variables are described in this paper as percentages, and continuous variables are expressed as medians and quartiles or means and standard deviations. Factors associated with prolonged treatment of pulmonary cryptococcosis with different imaging manifestations were estimated via multivariable analyses with the Cox proportional hazards model. A total of 238 patients were analysed. A significant proportion of patients with diabetes mellitus constituted 18% to 25% of patients with multiple nodules and diffuse infiltrates (p = 0.026). The serum antigen level was markedly elevated in patients with diffuse infiltrates and consolidation (p < 0.001). A significant proportion of patients who presented with solitary nodules were initially diagnosed through thoracic surgery conducted to remove the lesion (p < 0.001). The treatment duration for patients with pulmonary cryptococcosis presenting as single or multiple nodules on imaging was shorter than the traditionally considered 6 months (p < 0.001). Imaging revealed that pulmonary cryptococcosis most commonly involved the right lower lung. Serum antigen assays, the number of infectious lobes, the presence of extrapulmonary lesions and the presence of lesions in the lower right lobe were suggested to be predictive indicators for a longer treatment duration. There was no significant difference in the percentage of patients who used amphotericin B or amphotericin B liposomes among patients with the four different types of imaging presentations.
