BACKGROUND: Textbook outcome (TO) can guide decision-making among patients and clinicians during preoperative patient selection and postoperative quality improvement. We explored the factors associated with achieving a TO for gallbladder carcinoma (GBC) after curative-intent resection and analyzed the effect of adjuvant chemotherapy (ACT) on TO and non-TO patients. METHODS: A total of 540 patients who underwent curative-intent resection for GBC at the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2020 were retrospectively analyzed. Multivariable logistic regression was used to investigate the factors associated with TO. RESULTS: Among 540 patients with GBC who underwent curative-intent resection, 223 patients (41.3%) achieved a TO. The incidence of TO ranged from 19.0% to 51.0% across the study period, with a slightly increasing trend over the study period. The multivariate analysis showed that non-TO was an independent risk factor for prognosis among GBC patients after resection ( P = 0.003). Age ≤60 years ( P = 0.016), total bilirubin (TBIL) level ≤34.1 μmol/L ( P <0.001), well-differentiated tumor ( P = 0.008), no liver involvement ( P <0.001), and T1-2 stage disease ( P = 0.006) were independently associated with achieving a TO for GBC after resection. Before and after propensity score matching (PSM), the overall survival outcomes of non-TO GBC patients who received ACT and those who did not were statistically significant; ACT improved the prognosis of patients in the non-TO group ( P <0.05). CONCLUSION Achieving a TO is associated with a better long-term prognosis among GBC patients after curative-intent resection, and ACT can improve the prognosis of those with non-TO.

BACKGROUND: Gallbladder cancer (GBC) is the most common malignant tumor of biliary tract. Isoliquiritigenin (ISL) is a natural compound with chalcone structure extracted from the roots of licorice and other plants. Relevant studies have shown that ISL has a strong anti-tumor ability in various types of tumors. However, the research of ISL against GBC has not been reported, which needs to be further investigated. METHODS: The effects of ISL against GBC cells in vitro and in vivo were characterized by cytotoxicity test, RNA-sequencing, quantitative real-time polymerase chain reaction, reactive oxygen species (ROS) detection, lipid peroxidation detection, ferrous ion detection, glutathione disulphide/glutathione (GSSG/GSH) detection, lentivirus transfection, nude mice tumorigenesis experiment and immunohistochemistry. RESULTS: ISL significantly inhibited the proliferation of GBC cells in vitro . The results of transcriptome sequencing and bioinformatics analysis showed that ferroptosis was the main pathway of ISL inhibiting the proliferation of GBC, and HMOX1 and GPX4 were the key molecules of ISL-induced ferroptosis. Knockdown of HMOX1 or overexpression of GPX4 can reduce the sensitivity of GBC cells to ISL-induced ferroptosis and significantly restore the viability of GBC cells. Moreover, ISL significantly reversed the iron content, ROS level, lipid peroxidation level and GSSG/GSH ratio of GBC cells. Finally, ISL significantly inhibited the growth of GBC in vivo and regulated the ferroptosis of GBC by mediating HMOX1 and GPX4 . CONCLUSION ISL induced ferroptosis in GBC mainly by activating p62-Keap1-Nrf2-HMOX1 signaling pathway and down-regulating GPX4 in vitro and in vivo . This evidence may provide a new direction for the treatment of GBC.

Gallbladder cancer(GBC)is one common type of bile tract cancers with poor prognosis. This review summarizes the recent development of studies about somatic mutation, molecular subtype, microenvironment heterogeneity, organoid, orthotopic model, patient-derived xenograft and clinical translation on GBC in aspects of genomic,transcriptome,single cell omics and clinical translation. We expect this review will provide new ideas on dissecting molecular mechanisms underlying the development and emerging chemoresistance of GBC following therapy and promote GBC precision medicine.

Objective: To study the impact of regional positive lymph node ratio (LNR) on prognosis of patients with gallbladder carcinoma. Methods: The clinicopathological and survival data of 53 patients with gallbladder carcinoma who underwent radical resection with regional lymph node metastasis in Ningbo University Affiliated Lihuili Hospital from May 2012 to December 2020 were collected, and receiver operating characteristic curve (ROC) was used to determine the optimal cut-off value of LNR for predicting postoperative survival status in patients with gallbladder carcinoma. According to the critical value, the patients were divided into low LNR group and high LNR group. The clinicopathological features and prognosis of the two groups were compared. Log rank test was used for univariate analysis of prognostic factors in patients with gallbladder carcinoma, and Cox proportional hazards model was used for multivariate analysis. Results: A total of 417 regional lymph nodes were dissected in 53 patients, of which 144 lymph nodes were positive, with a positive rate of 34.5%. The optimal cut-off value of LNR for predicting postoperative survival status of patients with gallbladder carcinoma was 0.33. According to this cut-off value, patients were divided into low LNR group (LNR≤0.33, 28 cases) and high LNR group (LNR>0.33, 25 cases). The recurrence rates were 64.3% (18/28) and 88.0 % (22/25) in low LNR group and high LNR group, respectively. The median recurrence-free survival (RFS) was 8 and 7 months, respectively (P=0.032). In the low LNR group, the 1-, 3-, and 5-year survival rates were 56.2%, 38.4%, and 32.0%, respectively, and the median overall survival (OS) was 16 months. In the high LNR group, the 1-, 3-, and 5-year survival rates were 37.9%, 5.4%, and 0, respectively, and the median OS was 9 months. The postoperative survival rate of patients in the low LNR group was better than that in the high LNR group (P=0.008). Univariate analysis showed that LNR was even associated with RFS and OS in patients with gallbladder carcinoma (P<0.05). Multivariate analysis showed that LNR>0.33 was an independent risk factor for postoperative RFS (HR=1.977, 95% CI: 1.045-3.740), but not for OS (HR=1.561, 95% CI: 0.685-3.553). Conclusion: On the basis of clearing a sufficient number of regional lymph nodes, patients with gallbladder carcinoma with regional LNR>0.33 are more likely to relapse after operation, but the predictive value of LNR>0.33 OS is insufficient.

Objective: To compare the short-term efficacy and long-term prognosis of laparoscopic and laparotomy radical resection for gallbladder cancer(GBC). Methods: From January 2010 to December 2020,the clinical data and survival information for 133 patients who underwent radical resection of GBC at the Department of Hepatopancreatobiliary Surgery,Zhejiang Provincial People's Hospital,were retrospectively collected. Eighty patients(23 males and 57 females) underwent laparoscopic radical resection and had a median age(M(IQR)) of 66.0(12.8)years(range:28.0 to 82.0 years). Fifty-three patients(45 males and 8 females) who received laparotomy were 63.0(6.0)years old(range:45.0 to 80.0 years old). There were no significant differences in age,gender,body mass index,preoperative albumin,preoperative total bilirubin,N stages,vascular invasion,peri-neural invasion or tumor differentiation between the laparoscopic and laparotomy group(all P>0.05). But there were significant differences in preoperative CA19-9(Z=-2.955, P=0.003), preoperative ALT level(Z=-2.801,P=0.031) and T stage (χ²=19.110,P=0.007) between the two groups. A non-parametric test was used for quantitative data. χ² test or Fisher exact probability method was used for count data. Results: Patients in the laparoscopic group did not differ from those in the laparotomy group in terms of length of operation,number of lymph node yield,number of positive lymph nodes,the incidence of intraoperative gallbladder rupture,incidence of postoperative bile leakage,abdominal bleeding or abdominal infection,30-day mortality,90-day mortality, the incidence of incision implantation or peritoneal cavity metastasis(all P>0.05). Patients in the laparoscopic group showed less intraoperative bleeding(100.0(200.0)ml vs. 400.0(250.0)ml)(Z=-5.260,P<0.01),fewer days with drainage tube indwelling(6.0(3.8)days vs. 7.0(4.0)days)(Z=-3.351, P=0.001), and fewer postoperative days in hospital(8.0(5.0)days vs. 14.0(7.5)days)(Z=-6.079,P<0.01) than those in the laparotomy group. Patients in the laparoscopic group displayed better overall survival (P<0.01) and progression-free survival (P<0.01). Subgroup analysis for GBC of T1b-T2 and T3 stages revealed comparable overall survival and progression-free survival between the laparoscopic and laparotomy groups (P>0.05). Conclusions: Laparoscopic radical resection can achieve long-term survival for GBC comparable to that with open surgery. Laparoscopic radical resection has advantages over open surgery regarding surgical trauma and postoperative recovery.

Objective: To investigate the efficacy and safety of enhanced recovery after surgery (ERAS) in perioperative management of patients with gallbladder carcinoma. Methods: The data of the patients with gallbladder carcinoma admitted at Peking Union Medical College Hospital between January 2017 and December 2021 were analyzed retrospectively. There were 69 males(42.1%) and 95 females(57.9%),with age of (64.0±10.3) years(range:37 to 89 years). Patients were divided into ERAS group(n=53) and normal group(n=111) according to whether they were treated with ERAS measures during the perioperative period.The basic characteristics of the two groups were matched by propensity score matching,and then the perioperative information was compared between the two groups. Categorical variables were presented as absolute numbers or frequencies. Differences between study groups were analyzed using χ² test, Fisher's exact test, t-test, or Mann-Whitney U test, as appropriate. Results: Each group had 45 patients after propensity score matching with well-balanced basic characteristics. There was no difference in basic characteristics, operation time,bleeding,complication,and hospitalization expenses between two groups(all P>0.05). Compared with the normal group,time of ambulation (M(IQR)) (1(1) day vs. 2(2) days;Z=-3.839,P<0.01),postoperative anal exhaust time (2(1) days vs. 3(1) days;Z=-3.013,P=0.003),feeding time(2(1) days vs. 2(1) days;Z=-3.647,P<0.01),postoperative (5(2) days vs. 7(4) days;Z=-3.984,P<0.01) and total(8(4) days vs. 13(6) days;Z=-3.605,P<0.01) hospitalization time were shorter in ERAS group. Postoperative complications occurred in 12 patients. According to the Clavien-Dindo classification,6,4,and 2 patients were classified as grade Ⅰ,Ⅱ,and Ⅲa,respectively. Conclusion: The ERAS measures is safe and effective for perioperative management of patients with gallbladder carcinoma, enhancing patient recovery and shortening hospitalization time without increasing complication or hospitalization cost.
