| 1 | Laparoscopic surgery for early gallbladder carcinoma:A systematic review and meta-analysis显示文摘BACKGROUND There is a controversy as to whether laparoscopic surgery leads to a poor prognosis compared to the open approach for early gallbladder carcinoma (GBC)We hypothesized that the laparoscopic approach is an alternative for early GBC.AIM To identify and evaluate the safety and feasibility of laparoscopic surgery in the treatment of early GBC.METHODS A comprehensive search of online databases,including MEDLINE (PubMed),Cochrane libraries,and Web of Science,was performed to identify noncomparative studies reporting the outcomes of laparoscopic surgery and comparative studies involving laparoscopic surgery and open surgery in early GBC from January 2009 to October 2019.A fixed-effects meta-analysis was performed for 1-and 5-year overall survival and postoperative complications,while 3-year overall survival,operation time,blood loss,the number of lymph node dissected,and postoperative hospital stay were analyzed by random-effects models.RESULTS The review identified 7 comparative studies and 8 non-comparative studies.1068 patients (laparoscopic surgery:613;open surgery:455) were included in the meta-analysis of 1-,3-,and 5-year overall survival with no significant differences observed [(HR=0.54;95%CI:0.29-1.00;12=0.0%;P=0.051),(HR=0.75;95%CI:0.34-1.65;I^2=60.7%;P=0.474),(HR=0.71;95%CI:0.47-1.08;I^2=49.6%;P=0.107),respectively].There were no significant differences in operation time[weighted mean difference (WMD)=18.69;95%CI:-19.98-57.36;I^2=81.4%;P=0.343],intraoperative blood loss (WMD=-169.14;95%CI:-377.86-39.57;I2=89.5%;P=0.112),the number of lymph nodes resected (WMD=0.12;95%CI:-2.95-3.18;I^2=73.4%;P=0.940),and the complication rate (OR=0.69;95%CI:0.30-1.58;I2=0.0%;P=0.377) between the two groups,while patients who underwent laparoscopic surgery had a reduced length of hospital stay (WMD=-5.09;95%CI:-8.74--1.45;I2=91.0%;P=0.006).CONCLUSION This systematic review and meta-analysis confirms that laparoscopic surgery is a safe and feasible alternative to open surgery with comparable survival and operation-related outcomes for early GBC. | Xu Feng Jia-Sheng Cao Ming-Yu Chen Bin Zhang Sarun Juengpanich Jia-Hao Hu Win Topatana Shi-Jie Li Ji-Liang Shen Guang-Yuan Xiao Xiu-Jun Cai Hong Yu | 2020 | World Journal of Clinical Cases2020，8，6： | 6 |
| 2 | Prognostic factors and predictors of postoperative adjuvant transcatheter arterial chemoembolization benefit in patients with resected hepatocellular carcinoma显示文摘BACKGROUND Postoperative adjuvant transcatheter arterial chemoembolization (PA-TACE) has improved overall survival (OS) in patients with hepatocellular carcinoma (HCC).However,the prognostic and predictive factors remain unclear.AIM To assess the prognostic factors and the predictors of PA-TACE benefit for OS in patients with resected HCC.METHODS Univariate and multivariate analyses were performed to identify the potential prognostic factors for OS.In order to assess the predictive factors of PA-TACE benefit,the interaction variables between treatments for each subgroup were evaluated using the Cox proportional hazards regression model.RESULTS A total of 378 patients (PA-TACE vs surgery alone,189:189) from three centerswere included after a propensity-score 1:1 matching analysis.Compared to the group receiving surgery alone,PA-TACE prolonged the OS rate in patients with resected HCC (P <0.001).The Barcelona Clinic Liver Cancer system and ferritinto-hemoglobin ratio (FHR) were used as the prognostic factors for OS in both groups.Age (P=0.023) and microscopic vascular invasion (MVI)(P=0.002) were also identified in the PA-TACE group,while gender (P=0.027),hepatitis B virus(P=0.034) and albumin-bilirubin grade (P=0.027) were also selected in the surgery alone group.In addition,PA-TACE resulted in longer OS than surgery alone across subgroups [all hazard ratios (PA-TACE-to-surgery alone)<1].Notably,a significantly prolonged OS following PA-TACE was observed in patients with high FHR (P=0.038) and without MVI (P=0.048).CONCLUSION FHR and Barcelona Clinic Liver Cancer stages were regarded as prognostic factors for OS.Moreover,high FHR and the absence of MVI were important predictive factors,which can be used to assist clinicians in selecting which patients could achieve a better OS with PA-TACE. | Ming-Yu Chen Sarun Juengpanich Jia-Hao Hu Win Topatana Jia-Sheng Cao Chen-Hao Tong Jian Lin Xiu-Jun Cai | 2020 | World Journal of Gastroenterology2020，26，10： | 4 |
| 3 | Artificial intelligence in gastroenterology and hepatology:Status and challenges显示文摘Originally proposed by John McCarthy in 1955,artificial intelligence(AI)has achieved a breakthrough and revolutionized the processing methods of clinical medicine with the increasing workloads of medical records and digital images.Doctors are paying attention to AI technologies for various diseases in the fields of gastroenterology and hepatology.This review will illustrate AI technology procedures for medical image analysis,including data processing,model establishment,and model validation.Furthermore,we will summarize AI applications in endoscopy,radiology,and pathology,such as detecting and evaluating lesions,facilitating treatment,and predicting treatment response and prognosis with excellent model performance.The current challenges for AI in clinical application include potential inherent bias in retrospective studies that requires larger samples for validation,ethics and legal concerns,and the incomprehensibility of the output results.Therefore,doctors and researchers should cooperate to address the current challenges and carry out further investigations to develop more accurate AI tools for improved clinical applications. | Jia-Sheng Cao Zi-Yi Lu Ming-Yu Chen Bin Zhang Sarun Juengpanich Jia-Hao Hu Shi-Jie Li Win Topatana Xue-Yin Zhou Xu Feng Ji-Liang Shen Yu Liu Xiu-Jun Cai | 2021 | World Journal of Gastroenterology2021，27，16： | 3 |
| 4 | Identification of publication characteristics and research trends in the management of gallbladder cancer显示文摘Background:To date,no comprehensive analysis of gallbladder cancer(GBC)management has been reported.We aimed to identify the publication characteristics and research trends in managing GBC over the past three decades.Methods:We selected the 100 most cited articles and performed a bibliometric analysis to summarize the publication characteristics,explore research hotspots,and identify research trends in the management of GBC.Results:The total citations of the included articles ranged from 123 to 1822.Period II(2001–2010)yielded the highest number of included articles,whereas the lowest was in Period III(2011–2020).The United States and Japan published the most papers,in which the Memorial Sloan–Kettering Cancer Center and Nagoya University were the leading institutions,respectively.The most influential authors were Blumgart LH and Fong YM from the United States.Cooperation among countries,institutions,and authors was weak.The Annals of Surgery contributed the most articles with the highest number of total citations.The most researched topic was surgery,followed by systemic therapy and adjuvant therapy.Since Period I,the percentage of surgery-related publications continuously decreased(Periods II and III versus Period I,both p<0.001),with a concomitant increase in those of adjuvant therapy(Period III versus Period I,p=0.004)and systemic therapy(Period II versus Period I,p=0.004;Period III versus Period I,p=0.002).Conclusions:Surgery remains the preferred treatment,while there is a tendency toward adjuvant and systemic therapy in GBC management.An increase in local and international collaboration for managing GBC is required. | Jiasheng Cao Jiahao Hu Jiliang Shen Bin Zhang Win Topatana Shijie Li Tianen Chen Sarun Jeungpanich Yitong Tian Ziyi Lu Shuyou Peng Xiujun Cai Mingyu Chen | 2022 | iLIVER2022，1，2： | 0 |
| 5 | Development of synthetic lethality in cancer:molecular and cellular classification显示文摘Recently,genetically targeted cancer therapies have been a topic of great interest.Synthetic lethality provides a new approach for the treatment of mutated genes that were previously considered unable to be targeted in traditional genotype-targeted treatments.The increasing researches and applications in the clinical setting made synthetic lethality a promising anticancer treatment option.However,the current understandings on different conditions of synthetic lethality have not been systematically assessed and the application of synthetic lethality in clinical practice still faces many challenges.Here,we propose a novel and systematic classification of synthetic lethality divided into gene level,pathway level,organelle level,and conditional synthetic lethality,according to the degree of specificity into its biological mechanism.Multiple preclinical findings of synthetic lethality in recent years will be reviewed and classified under these different categories.Moreover,synthetic lethality targeted drugs in clinical practice will be briefly discussed.Finally,we will explore the essential implications of this classification as well as its prospects in eliminating existing challenges and the future directions of synthetic lethality. | Shijie Li Win Topatana Sarun Juengpanich Jiasheng Cao Jiahao Hu Bin Zhang Diana Ma Xiujun Cai Mingyu Chen | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |
