Objective:To investigate the impact of Tumor-Infiltrating Lymphocytes (TILs) density in the tumor stroma on the long-term prognosis of hepatocellular carcinoma (HCC) liver transplant patients meeting the Hangzhou criteria.Methods:This study is a retrospective cohort study. The clinical data of 83 patients with hepatocellular carcinoma who met the Hangzhou criteria and underwent allogeneic liver transplantation from January 2018 to December 2023 in the Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital affiliated to Capital Medical University were collected and analyzed. Hematoxylin and Eosin (HE) staining was used to study the density of TILs in the resected liver grafts. Patients were divided into TILs-negative group (TILs<10%, n=31) and TILs-positive group (TILs≥10%, n=52) based on whether the TILs density exceeded 10%. Clinical and pathological characteristics were analyzed, and the significance of alpha-fetoprotein (AFP), TILs density, and microvascular invasion on the prognosis of HCC patients who met the Hangzhou criteria was studied. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s) and compared between groups using t-test. Measurement data with skewed distribution were expressed as M ( Q1, Q3) and compared using rank-sum tests. Categorical data were compared using chi-square test. Kaplan-Meier method was used to study the relationship between various observation indicators and overall survival, and survival curves were plotted. Log-rank test was used to compare the survival rates between groups, and multivariate Cox regression model was used to adjust for the distribution of risk factors between groups. Results:The preoperative AFP level in the TILs-negative group was (15.69±1.21) U/mL, and in the TILs-positive group was (12.17±0.13) U/mL, with a statistically significant difference between the two groups ( P<0.05). In the TILs-negative group, 8 cases had microvascular invasion, and the number of low, moderate, and high differentiation tumors was 8, 23, and 0, respectively. In the TILs-positive group, 3 cases had microvascular invasion, and the number of low, moderate, and high differentiation tumors was 2, 31, and 19, respectively. The results indicated that patients in the TILs-negative group were more likely to have microvascular invasion and poorer tumor differentiation ( P<0.05). All patients were regularly followed up, and the 1-, 2-, and 3-year survival rates in the TILs-negative group and TILs-positive group were 84.0%, 77.6%, 69.8%, and 94.7%, 91.7%, 86.6%, respectively ( P<0.01). Cox proportional hazards model indicated that microvascular invasion ( RR=4.474, 95% CI: 1.172-17.072, P=0.028) and TILs-negative status ( RR=5.081, 95% CI: 1.420-18.184, P=0.012) were independent risk factors for the long-term prognosis of HCC patients who met the Hangzhou criteria. Conclusions:Among HCC patients meeting the Hangzhou criteria, the density of TILs in the tumor stroma is related to AFP levels, tumor differentiation, and the presence of microvascular invasion. TILs-negative status indicates a poorer prognosis for these patients.

This study followed up the immune memory after 3-dose revaccination among infants with non-and low-response following primary hepatitis B (HepB) vaccination. About 120 children without self-booster doses were finally included who had anti-HBs<10 mIU/ml (anti-HBs negative) at the time of follow-up, of whom 86 children completed blood sampling and anti-HBs testing. Before the challenge dose, all 86 children were negative for anti-HBs, and the GMC of anti-HBs was<10 mIU/ml. The seropositive conversion rate of anti-HBs was 100% and the GMC of anti-HBs was 886.11 (95%CI: 678.15-1 157.84) mIU/ml after the challenge dose. Compared with those with GMC<7 mIU/ml before the challenge dose, infants with GMC>7 mIU/ml had a higher anti-HBs level after the challenge dose. The β value (95%CI) was 0.82 (0.18-1.46) (P=0.012). Compared with those with GMC<1 000 mIU/ml at primary vaccination, infants with GMC≥1 000 mIU/ml had a higher anti-HBs level after the challenge dose. The β value (95%CI) was 0.78 (0.18-1.38)(P=0.012). The results showed a stronger immune memory was found at 9 years after revaccination among infants with non-and low-response to HepB.

Objective:To analyse the correlation between the lymph nodes, the number of positive lymph nodes, the positive rate of lymph nodes and the long-term prognosis of patients with distal cholangiocarcinoma.Methods:The clinical data and follow-up results of 104 patients with distal cholangiocarcinoma admitted to Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2015 to December 2021 were retrospectively analyzed using a retrospective cohort study. All patients underwent pancreaticoduodenectomy. According to the nature of the patients′ lymph nodes, the number of positive lymph nodes, and the positive rate of lymph nodes, the X-tile software was used to analyze data respectively, and the critical value of SUVmax were determined, and the patients were divided into low-risk group and high-risk group by critical values. Based on this critical value, the patients were divided into low-risk groups and high-risk groups. There were 37 patients in the lymph node positive group and 67 patients in the negative group. In the lymph node positive group, according to the number of positive lymph nodes (the cut-off value=2), they were divided into the low-risk group( n=14), the high-risk group( n=23); grouped according to the lymph node positive rate (the cut off=0.13), and divided into the low-risk group( n=15), and the high-risk group( n=22). After grouping according to different lymph node parameters, the preoperative general data such as age, gender, laboratory examination, etc., the correlation between perioperative complications and long-term prognosis were analyzed. The measurement data conforming to the normal distribution was expressed as mean ± standard deviation( ± s), and the t test was used for comparison between groups; the measurement data that was not normally distributed was expressed as M ( Q1, Q3), and the comparison between groups was performed by the rank sum test. The enumeration data were expressed by the number of cases, and the comparison between groups was performed using the chi-square test. If the total number of cases was less than 50, and Fisher′s exact test was used. The optimal cut-off values for different lymph node parameters were determined using the x-tile 3.6.1 software. Survival curves were calculated and drawn using the Kaplan-Meier method, and the survival rates were compared using the Log-rank test. Results:All patients successfully underwent the operation, 5 patients(4.8%) died during the perioperative period. The median postoperative survival time of lymph node-positive patients and lymph node-negative patients was 17 months and 36 months, respectively, and the overall survival rates at 1, 3, and 5 years were 64.9%, 23.9%, 23.9%, and 81.5%, 49.8%, 41.7%( P=0.003). Among the patients grouped according to the number of positive lymph nodes, the median postoperative survival time of patients in the low-risk group and the high-risk group was 21 months and 17 months, and the 1-, 3-, and 5-year overall survival rates of the two groups were were 77.1%, 42.9%, 42.9% and 58.2%, 13.8%, 13.8%( P=0.284), respectively. Among the patients grouped according to the positive rate of lymph nodes, the median postoperative survival time of the patients in the low-risk group and the high-risk group was 30 months and 15 months, and the 1-, 3-, and 5-year overall survival rates of the two groups were 85.6%, 42.7%, 42.7% and 51.3%, 10.3%, 0.3%( P=0.020), respectively. Conclusions:Radical pancreaticoduodenectomy is the standard procedure for patients with distal cholangiocarcinoma. The prognosis of patients with positive lymph nodes is worse. For patients with positive lymph nodes, the positive rate of lymph nodes is a better predictor of the long-term prognosis compared with the number of positive lymph nodes.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective To investigate the application value of transjugular liver biopsy (TJLB) in the diagnosis and treatment of complicated and severe liver diseases. Methods A retrospective analysis was performed for the clinical data of 31 patients who underwent TJLB in The Fifth Medical Center of Chinese PLA General Hospital, including indication for puncture, success rate, and final diagnosis. Results Among the 31 patients, there were 15 male patients and 16 female patients. Percutaneous liver biopsy was unsuitable for 8 patients with liver failure and disturbances of blood coagulation, 13 with liver cirrhosis and ascites, and 10 with liver cirrhosis and thrombocytopenia (< 50×10 9 /L), which were the indications for TJLB. The success rate of TJLB puncture was 100%, with 2-4 passes for puncture. No serious adverse event was observed. Of all 31 patients, 26 (83.87%) had a definite diagnosis at discharge, among whom there were 5 patients with idiopathic portal hypertension, 9 patients with drug-induced liver failure or liver cirrhosis, 5 patients with autoimmune liver disease, and 7 patients with liver cirrhosis or liver failure due to other causes, and 5 patients had unknown etiology. In addition, 3 patients underwent biopsy to confirm the diagnosis and decision of whether liver transplantation should be performed. Conclusion TJLB plays an important role in the diagnosis and treatment of complicated and severe liver diseases and still has certain limitations, and therefore, suitable patients should be selected in clinical practice.

Objective To analyze the application and effect of non-penetrating vascular and tubular tissue closure system in radical resection of adenocarcinoma of pancreatic head combined with venous resection and reconstruction.Methods A retrospective analysis was made on the clinical data of 78 patients with pancreatic head cancer who underwent radical resection of venous vessels from Feb 2014 to Feb 2018.According to the intraoperative venous resection and anastomosis,the patients were divided into vascular clip group (41 cases) and traditional suture group (37 cases).The preoperative data,intraoperative and postoperative recovery of the two groups were analyzed and compared.Results There were no perioperative deaths and no significant differences in perioperative complications between the two groups (P ＞ 0.05).The anastomotic time of the clip group was (18.6 ± 3.3) min,which was significantly shorter than that of the traditional suture group (39.7 ± 8.5) min,(P ＜ 0.05).There were no significant differences in operation time,intraoperative bleeding volume,ICU time,hospital stay and anastomotic stenosis between the two groups(P＞ 0.05).Conclusion It is safe and feasible to use vascular clip in venous vascular reconstruction in radical resection of carcinoma of the head of the pancreas combined with venous vascular resection.

Objective To evaluate the prognosis and related risk factors in patients with primary liver cancer after liver transplantation. Methods We retrospectively analyzed the clinical data of 298 patients who underwent liver transplantation between January 2013 and December 2017 at Beijing Chaoyang Hospital of Capital Medical University. 121 patients with primary liver cancer on postoperative pathological diagnosis were included into this study. The patients included 108 males and 13 females, aged from 31 to 70 years, with an average of (52. 7 ± 8. 7) years. The prognosis and the related risk factors on prognosis were analyzed. The survival curve was drawn by the Kaplan-Meier method, and the survival rate was compared by the log-rank test. Multivariate Cox regression was used to analyze the prognostic factors. Results Of the 121 patients who were enrolled in this study, 5 patients died during the perioperative period, making a perioperative mortality rate of 4. 1% (5/121). The remaining 115 patients were followed up and the followed up rate was 95. 0% (115/121). The overall 1-, 2- and 3-year survival rates were 81. 0% , 74. 6% and 70. 2% , respectively. The median survival was 41. 5 months. Multivariate analysis showed that preoperative Child grading (RR=3. 028, 95% CI: 1. 625～5. 643) and microvascular invasion (RR=7. 165, 95% CI: 2. 237～22. 951) were independent risk factors of prognosis. The worse the preoperative Child grading, the worse was the prognosis. The prognosis of patients with microvascular invasion was also poor. Conclusions The overall prognosis of patients with primary liver cancer after liver transplantation was good. Preoperative Child grading and pathological microvascular invasion were the main risk factors of prognosis after liver transplantation carried out for primary liver cancer.

Objective To evaluate rapid frozen pathology in the operation of hilar cholangiocarcinoma.Methods Clinical data of 49 patients of hilar cholangiocarcinoma undergoing surgical treatment were analyzed retrospectively from Jan 2011 to Dec 2017 at Department of Hepatobiliary Surgery,Beijing Chaoyang Hospital Affiliated to Capital Medical University to evaluate rapid frozen pathology on operative strategy of hilar cholangiocarcinoma and the prognosis of patients.Results All patients with hilar cholangiocarcinoma underwent intraoperative frozen pathological examination.5 patients adjusted the operation approach because of the discrepancy between frozen pathological examination and preoperative imaging results.47 intraoperative frozen pathological results were consistent with postoperative pathological diagnosis,and the accuracy rate was 95.9％,sensitivity 90％,specificity 97.4％,false positive rate 2.6％,false negative rate 10％.Frozen section margin negative patients had significantly longer survival time(P ＜ 0.05).Conclusions Intraoperative frozen pathological examination can guide the operation approach,greatly improve the resection rate of R0 and the prognosis of patients.
