Laparoscopic liver resection under hemihepatic vascular inflow occlusion using the lowering of hilar plate approach.

BACKGROUND: With advances in technology, laparoscopic liver resection is widely accepted. Laparoscopic liver resection under hemihepatic vascular inflow occlusion has advantages over the conventional total hepatic inflow occlusion using the Pringle's maneuver, especially in patients with cirrhosis. METHOD: From November 2011 to August 2012, eight consecutive patients underwent laparoscopic liver resection under hemihepatic vascular inflow occlusion using the lowering of hilar plate approach with biliary bougie assistance. RESULTS: The types of liver resection included right hepatectomy (n=1), right posterior sectionectomy (n=1), left hepatectomy and common bile duct exploration (n=1), segment 4b resection (n=1), left lateral sectionectomy (n=2), and wedge resection (n=2). Four patients underwent right and 4 left hemihepatic vascular inflow occlusion. Four patients had cirrhosis. The mean operation time was 176.3 minutes. The mean time taken to achieve hemihepatic vascular inflow occlusion was 24.3 minutes. The mean duration of vascular inflow occlusion was 54.5 minutes. The mean intraoperative blood loss was 361 mL. No patient required blood transfusion. Postoperatively, one patient developed bile leak which healed with conservative treatment. No postoperative liver failure and mortality occurred. The mean hospital stay of the patients was 7 days. CONCLUSION: Our technique of hemihepatic vascular inflow vascular occlusion using the lowering of hilar plate approach was safe, and it improved laparoscopic liver resection by minimizing blood loss during liver parenchymal transection.

Effects of Preservation of Donor Liver Gastroduodenal Artery on Post-Transplant Biliary Complications in 187 Liver Transplant Recipients: A Retrospective Study.

BACKGROUND This retrospective study aimed to evaluate the effects of preservation of the donor liver gastroduodenal artery on post-transplant biliary complications in 187 liver transplant recipients. MATERIAL AND METHODS The clinical data of 187 liver transplantation recipients were retrospectively analyzed. Recipients were divided into conventional and modified groups. The technical point of the modified group is to preserve at least 2 cm of the distal gastroduodenal artery, and pay special attention to preserve the superior pancreaticoduodenal artery to ensure the distal blood supply to the common bile duct. RESULTS The modified group had significantly shorter operative time (7.17 vs 7.98) h (P<0.001) and less intraoperative blood loss (2715.40 vs 3434.93) ml (P=0.003) than the conventional group. The incidence of postoperative biliary complications (including anastomotic biliary leakage, ischemic bile duct stenosis, and anastomotic bile duct stenosis) in the modified group (4/114, 4.1%) was significantly lower (15/73, 20.5%) (P<0.001). There was no significant difference in the intraoperative cold and warm ischemia time and postoperative hospital stay length between the 2 groups. In addition, there was no significant difference in the effect of cardiac-death and brain-death sources on perioperative biliary complications, while the peak postoperative transaminase and total bilirubin were higher in patients receiving the donor liver of cardiac death (P<0.05). CONCLUSIONS Preserving the integrity of the donor gastroduodenal artery and surrounding tissue is beneficial to protect the blood supply of the extrahepatic bile duct, and can reduce the incidence of biliary complications.

Postoperative Adjuvant Hepatic Arterial Infusion Chemotherapy With FOLFOX in Hepatocellular Carcinoma With Microvascular Invasion: A Multicenter, Phase III, Randomized Study.

PURPOSE: To report the efficacy and safety of postoperative adjuvant hepatic arterial infusion chemotherapy (HAIC) with 5-fluorouracil and oxaliplatin (FOLFOX) in hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI). PATIENTS AND METHODS: In this randomized, open-label, multicenter trial, histologically confirmed HCC patients with MVI were randomly assigned (1:1) to receive adjuvant FOLFOX-HAIC (treatment group) or routine follow-up (control group). The primary end point was disease-free survival (DFS) by intention-to-treat (ITT) analysis while secondary end points were overall survival, recurrence rate, and safety. RESULTS: Between June 2016 and August 2021, a total of 315 patients (ITT population) at five centers were randomly assigned to the treatment group (n = 157) or the control group (n = 158). In the ITT population, the median DFS was 20.3 months (95% CI, 10.4 to 30.3) in the treatment group versus 10.0 months (95% CI, 6.8 to 13.2) in the control group (hazard ratio, 0.59; 95% CI, 0.43 to 0.81; P = .001). The overall survival rates at 1 year, 2 years, and 3 years were 93.8% (95% CI, 89.8 to 98.1), 86.4% (95% CI, 80.0 to 93.2), and 80.4% (95% CI, 71.9 to 89.9) for the treatment group and 92.0% (95% CI, 87.6 to 96.7), 86.0% (95% CI, 79.9 to 92.6), and 74.9% (95% CI, 65.5 to 85.7) for the control group (hazard ratio, 0.64; 95% CI, 0.36 to 1.14; P = .130), respectively. The recurrence rates were 40.1% (63/157) in the treatment group and 55.7% (88/158) in the control group. Majority of the adverse events were grade 0-1 (83.8%), with no treatment-related death in both groups. CONCLUSION: Postoperative adjuvant HAIC with FOLFOX significantly improved the DFS benefits with acceptable toxicities in HCC patients with MVI.

Hepatic Arterial Infusion of Oxaliplatin, Fluorouracil, and Leucovorin Versus Transarterial Chemoembolization for Large Hepatocellular Carcinoma: A Randomized Phase III Trial.

PURPOSE: In a previous phase II trial, hepatic arterial infusion chemotherapy (HAIC) with infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX) yielded higher treatment responses than transarterial chemoembolization (TACE) in large unresectable hepatocellular carcinoma. We aimed to compare the overall survival of patients treated with FOLFOX-HAIC versus TACE as first-line treatment in this population. METHODS: In this randomized, multicenter, open-label trial, adults with unresectable hepatocellular carcinoma (largest diameter ≥ 7 cm) without macrovascular invasion or extrahepatic spread were randomly assigned 1:1 to FOLFOX-HAIC (oxaliplatin 130 mg/m2, leucovorin 400 mg/m2, fluorouracil bolus 400 mg/m2 on day 1, and fluorouracil infusion 2,400 mg/m2 for 24 hours, once every 3 weeks) or TACE (epirubicin 50 mg, lobaplatin 50 mg, and lipiodol and polyvinyl alcohol particles). The primary end point was overall survival by intention-to-treat analysis. Safety was assessed in patients who received ≥ 1 cycle of study treatment. RESULTS: Between October 1, 2016, and November 23, 2018, 315 patients were randomly assigned to FOLFOX-HAIC (n = 159) or TACE (n = 156). The median overall survival in the FOLFOX-HAIC group was 23.1 months (95% CI, 18.5 to 27.7) versus 16.1 months (95% CI, 14.3 to 17.9) in the TACE group (hazard ratio, 0.58; 95% CI, 0.45 to 0.75; P < .001). The FOLFOX-HAIC group showed a higher response rate than the TACE group (73 [46%] v 28 [18%]; P < .001) and a longer median progression-free survival (9.6 [95% CI, 7.4 to 11.9] v 5.4 months [95% CI, 3.8 to 7.0], P < .001). The incidence of serious adverse events was higher in the TACE group than in the FOLFOX-HAIC group (30% v 19%, P = .03). Two deaths in the FOLFOX-HAIC group and two in the TACE group were deemed to be treatment-related. CONCLUSION: FOLFOX-HAIC significantly improved overall survival over TACE in patients with unresectable large hepatocellular carcinoma.

Lenvatinib, toripalimab, plus hepatic arterial infusion chemotherapy versus lenvatinib alone for advanced hepatocellular carcinoma.

BACKGROUND: Lenvatinib is the first-line treatment for advanced hepatocellular carcinoma, but prognosis is still unsatisfactory. Recently, hepatic arterial infusion chemotherapy (HAIC), and immune checkpoint inhibitors showed promising results for advanced hepatocellular carcinoma. Considering different anti-malignancy mechanisms, combining these three treatments may improve outcomes. This study aimed to compare the efficacy and safety of lenvatinib, toripalimab, plus HAIC versus lenvatinib for advanced hepatocellular carcinoma. METHODS: This was a retrospective study including patients treated with lenvatinib [8 mg (⩽60 kg) or 12 mg (>60 kg) once daily] or lenvatinib, toripalimab plus HAIC [LeToHAIC group, lenvatinib 0-1 week prior to initial HAIC, 240 mg toripalimab 0-1 day prior to every HAIC cycle, and HAIC with FOLFOX regimen (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 on day 1, and 5-fluorouracil infusion 2400 mg/m2 for 46 h, every 3 weeks)]. Progression-free survival, overall survival, objective response rate, and treatment-related adverse events were compared. RESULTS: From February 2019 to August 2019, 157 patients were included in this study: 71 in the LeToHAIC group and 86 in the lenvatinib group. The LeToHAIC group showed longer progression-free survival (11.1 versus 5.1 months, p < 0.001), longer overall survival (not reached versus 11 months, p < 0.001), and a higher objective response rate (RECIST: 59.2% versus 9.3%, p < 0.001; modified RECIST: 67.6% versus 16.3%, p < 0.001) than the lenvatinib group. In addition, 14.1% and 21.1% of patients in the LeToHAIC group achieved complete response of all lesions and complete response of the intrahepatic target lesions per modified RECIST criteria, respectively. Grade 3/4 treatment-related adverse events that were more frequent in the LeToHAIC group than in the lenvatinib group included neutropenia (8.5% versus 1.2%), thrombocytopenia (5.6% versus 0), and nausea (5.6% versus 0). CONCLUSIONS: Lenvatinib, toripalimab, plus HAIC had acceptable toxic effects and might improve survival compared with lenvatinib alone in advanced hepatocellular carcinoma.

Toripalimab Combined With Hepatic Arterial Infusion Chemotherapy Versus Lenvatinib for Advanced Hepatocellular Carcinoma.

Purpose: Immunotherapy combined with chemotherapy have synergistic effects in multiple malignancies. We aimed to compare the efficacy and safety of toripalimab plus hepatic arterial infusion chemotherapy (HAIC) of oxaliplatin, fluorouracil, and leucovorin versus lenvatinib in advanced hepatocellular carcinoma (HCC). Materials and Methods: We conducted this retrospective study at 3 hospitals in China and eligible patients were 18 years or older and had a primary diagnosis of unresectable HCC with macroscopic vascular invasion and/or extrahepatic spread. These patients were treated with toripalimab plus HAIC or lenvatinib monotherapy. The primary endpoint was progression-free survival (PFS) and the secondary endpoints were overall survival (OS), disease control rate per response evaluation criteria in solid tumors (RECIST) 1.1, and objective response rate (ORR) per RECIST 1.1. The results were compared by Student's test or the chi-square test, and the survival curves were calculated by the Kaplan-Meier method, and propensity-score matching (PSM) was used to reduce bias. Results: A total of 118 patients were recruited for this study: 53 in the TorHAIC group and 65 in the lenvatinib group. We found that the TorHAIC group showed a longer PFS (9.3 [95% CI, 7.81-10.8] vs 4.8 months [95% CI, 3.31-6.29]; hazard ratio [HR] = 0.57, 95% CI, 0.38-0.85; p = .006), a longer OS (17.13 [95% CI, 13.99-20.27] vs 10.1 months [95% CI, 8.14-12.06]; HR = 0.5, 95% CI, 0.31 - 0.81; p = .005), a higher disease control rate (86.8% vs 69.2%, p = .002) and a higher ORR (47.2% vs 9.2%, p < .001) by RECIST criteria than the lenvatinib group. Both toripalimab plus HAIC and lenvatinib had acceptable safety profiles. No treatment-related deaths occurred in this study. In the propensity score-matched cohorts (47 pairs), the outcomes in the TorHAIC group were also better than those in the lenvatinib group (p < .05). Conclusion: Toripalimab plus HAIC was tolerable and effective in advanced HCC and the result needs to be confirmed in the phase III trial.

Right Hemihepatectomy via an Anterior Approach for Hepatocellular Carcinoma in a Situs Inversus Totalis Patient.

Situs inversus totalis (SIT) is a rare congenital condition in which the usual position of the organs is reversed from left to right as a mirror image of the normal situation. Due to the abnormal transposition, this represents a technical challenge for the surgeon. In the present study, right hemihepatectomy via the anterior approach was performed for a 68-year-old hepatocellular carcinoma (HCC) patient with SIT. SIT was diagnosed by chest X-ray and computed tomography. The tumors were located in segments VIII and VI of the liver, and there was no metastasis to the lymph nodes and distant organs. Hemihepatic vascular inflow occlusion was performed using the selective intra-Glissonian approach. The middle hepatic vein was preserved under the guidance with intraoperative ultrasonography. The present case suggests that right hemihepatectomy via the anterior approach may be a safe, feasible, and effective procedure for HCC patients with SIT.

Nelumbo nucifera leaves extract attenuate the pathological progression of diabetic nephropathy in high-fat diet-fed and streptozotocin-induced diabetic rats.

Diabetic nephropathy is not only a common and severe microvascular complication of diabetes mellitus but also the leading cause of renal failure. Lotus (Nelumbo nucifera) possesses antioxidative and anticancer properties. The present study aimed to investigate the antidiabetic and renoprotective effects of N. nucifera leaf extract (NLE) in a rat model of type 2 diabetic mellitus. Male Sprague-Dawley rats with type 2 diabetes induced by a high-fat diet (HFD)/streptozotocin (STZ) were treated with NLE at dosages of 0.5% and 1% (w/w) daily for 6 weeks. At the end of the experimental period, body weight, serum glucose levels, insulin levels, and kidney function were assessed. Furthermore, antioxidant enzyme and lipid peroxide levels were determined in the kidney, and histopathological examination was performed using hematoxylin and eosin staining, periodic acid Schiff staining, and Masson trichrome staining. To shed light on the molecular mechanism underlying the functioning of NLE, mouse glomerular mesangial cells (MES-13) treated with high glucose (HG, 25 mM glucose) were chosen as a model for an examination of the signal transduction pathway of NLE. The results revealed that NLE improved diabetic kidney injury by reducing blood glucose, serum creatinine, and blood urea nitrogen levels and enhanced antioxidant enzyme activities in kidney tissue. Treatment with NLE significantly reduced the malondialdehyde and 8-hydroxy-2-deoxyguanosine levels and increased serum insulin levels; expression of renal superoxide dismutase, catalase, and glutathione peroxidase activities; and glutathione content. Histological studies have also demonstrated that NLE treatment inhibited the dilation of Bowman's capsule, which confirmed its renoprotective action in diabetes. In addition, treatment with NLE and its major component quercetin 3-glucuronide attenuated 25 mM HG-induced suppressed nuclear factor erythroid 2-related factor 2 and antioxidant enzyme expression in MES-13 cells. Collectively, these findings indicate that NLE may have antidiabetic and renoprotective effects against HFD/STZ-induced diabetes, at least in part, through antioxidative pathways.

Extra-Glissonian Approach for Laparoscopic Liver Right Anterior Sectionectomy.

BACKGROUND: Open right anterior sectionectomy, which involves resection of liver segments 5 and 8, has been reported to have similar postoperative mortality rates as right hepatectomy, but it has a decreased risk in developing posthepatectomy liver failure. Totally laparoscopic right anterior sectionectomy is technically demanding and has rarely been reported in hepatocellular carcinoma (HCC) patients with cirrhosis. METHODS: Our experience in carrying out totally laparoscopic right anterior sectionectomy on four consecutive HCC patients with cirrhosis from November 2016 to August 2017 using the extraglissonian approach formed the basis of this report. RESULTS: All four patients had hepatitis B-related HCC. The mean operation time was 502 ± 55 minutes. All patients underwent intermittent Pringle's Maneuver with cycles of clamp/unclamp times of 15/5 minutes for the left-sided liver transection plane, and intermittent right hemihepatic vascular inflow occlusion with cycles of clamp/unclamp times of 30/5 minutes for the right-sided liver transection plane. The mean Pringle's Maneuver time was 58.8 ± 11.4 minutes and the mean right hemihepatic vascular inflow occlusion time was 66.3 ± 11.1 minutes. The mean intraoperative blood loss was 512 ± 301 mL. No patients required any blood transfusion. There was no conversion to open surgery. Postoperative complications included intra-abdominal bleeding requiring reoperation for hemostasis (n = 1), intra-abdominal collection requiring percutaneous drainage (n = 1), and right pleural effusion requiring percutaneous drainage (n = 1). There was no 90-day postoperative mortality. The mean hospital stay was 10.7 ± 2.9 days. After a median follow-up of 10 (range, 6-16) months, one patient developed HCC recurrence in the liver remnant. CONCLUSION: Totally laparoscopic right anterior sectionectomy using the extraglissonian approach was technically feasible and safe in expert hands. More data are needed to assess the long-term oncological survival outcomes.

Inflammatory myofibroblastic tumours of the spleen and liver.

Inflammatory myofibroblastic tumour (IMT) is a rare neoplasm. Generally, these lesions have a benign behaviour, but the possibility of malignant transformation exists. We report the rare case of a 43-year-old woman with metachronous IMTs in the spleen and the liver. The patient was treated with laparoscopic splenectomy and partial hepatectomy. The patient recovered uneventfully. This case emphasizes the difficulties in diagnosis and the possibility of a metachronous occurrence.

Laparoscopic Right Hepatectomy Via an Anterior Approach for Hepatocellular Carcinoma.

BACKGROUND AND OBJECTIVES: In the past, right hepatectomy via the anterior approach has been regarded as one of the many standard approaches for hepatectomy. However, total laparoscopic right hepatectomy from the anterior approach has been regarded as technically challenging. We report our experience in using the anterior approach in total laparoscopic right hepatectomy for hepatocellular carcinoma (HCC). METHODS: From June 2013 through December 2015, five consecutive patients underwent total laparoscopic right hepatectomy using the anterior approach, but without the hanging maneuver. RESULTS: The mean operative time was 360 (range, 300-480) minutes, and the mean blood loss was 340 (110-600) mL. No patient needed any blood transfusion. There was no conversion to open surgery. Ascites, pleural effusion, and bile leakage occurred in 2, 1, and 1 patients, respectively. No patients expired as a result of the surgery or liver failure. The mean hospital stay was 7 (4-15) days. All patients had R0 resection. After a mean follow-up of 22 (8-33) months, no patients experienced recurrence of disease. CONCLUSION: Total laparoscopic right hepatectomy using the anterior approach is feasible and safe.

T cell receptor repertoire profiling predicts the prognosis of HBV-associated hepatocellular carcinoma.

Tumor-infiltrating T cell repertoire has been demonstrated to be closely associated with anti-tumor immune response. However, the relationship between T cell repertoire in tumor tissue and prognosis has never been reported in Hepatocellular carcinoma (HCC). We performed the high-throughput T cell receptor (TCR) sequencing to systematically characterize the infiltrating T cell repertoires of tumor and matched adjacent normal tissues from 23 HBV-associated HCC patients. Significant differences on usage frequencies of some Vß, Jß, and Vß-Jß paired genes have been found between the 2 groups of tissue samples, but no significant difference of TCR repertoire diversity could be found. Interestingly, the similarity of TCR repertoires between paired samples or the TNM stage alone could not be helpful to evaluate the prognosis of patients very well, but their combination could serve as an efficient prognostic indicator that the patients with early stage and high similarity showed a better prognosis. This is the first attempt to assess the potential value of TCR repertoire in HCC prognosis, and our findings could serve as a complement for the characterization of TCR repertoire in HCC.

Extra-glissonian Approach for Total Laparoscopic Left Hepatectomy: A Prospective Cohort Study.

Laparoscopic liver resection under hemihepatic vascular inflow control has advantages over Pringle's maneuver, especially in patients with cirrhosis. From January 2016 to August 2016, 7 patients who underwent total laparoscopic left hepatectomy under hemihepatic vascular inflow occlusion using the extra-glissonian approach were included in this study. All were hepatitis B carriers and 4 had cirrhosis. The mean operation time was 247 minutes. The mean transection time was 110 minutes. No patient needed additional Pringle's maneuver. The mean intraoperative blood loss was 74 ml and no patient required blood transfusion. No open conversion happened. Postoperatively, no patient developed complications and there was no perioperative mortality. The mean resection margin was 2 cm. The mean hospital stay was 6 days. Upon a mean follow-up of 9 months, no patient developed tumor recurrence. The technique of total laparoscopic left hepatectomy using extra-glissonian approach was safe and feasible. The early surgical outcomes were good.

Anterior approach for right hepatectomy using the 5-steps stapling technique: A preliminary study.

INTRODUCTION: Right hepatectomy via the anterior approach without prior liver mobilization is an accepted technique and the liver hanging maneuver facilitates this procedure. Hepatic parenchymal transection remains a critical part of this operation during which excessive blood loss can occur. Control of blood loss is important in hepatectomy as excessive bleeding and blood transfusion are associated with increased postoperative morbidity/mortality rates and compromised long-term oncological outcomes in these patients. METHODS: A 5-steps stapling technique was developed to decrease blood loss during right hepatectomy using the anterior approach with the liver hanging maneuver. All consecutive patients who underwent elective right hepatectomy in our center using this technique from January 2014 to June 2015 were retrospectively studied. This study aimed to describe this technique and report the preliminary outcomes. RESULTS: Eleven patients with hepatitis B-related hepatocellular carcinoma (HCC) with cirrhosis underwent the 5-steps stapling technique for right hepatectomy using the anterior approach with the liver hanging maneuver. The mean blood loss, liver parenchymal transection time and operation time were 227.3 ± 91.4 ml (SD), 40.0 ± 7.8 min, and 261.8 ± 48.5 min, respectively. No patients developed postoperative bleeding or bile leak. There was no 90-day mortality. CONCLUSION: The preliminary results of this 5-steps stapling technique for right hepatectomy using the liver hanging maneuver are encouraging as the technique resulted in little intraoperative blood loss and short operation time, and it caused no major complications and mortality.

[Clinical experience with 13 cases of orthotopic liver transplantation].

OBJECTIVE: To review our experience with orthotopic liver transplantation. METHODS: Thirteen liver transplantation were performed in 12 patients (including one liver retransplantation), of whom 5 patients received the transplantation for end stage liver cirrhosis, 4 for primary liver carcinoma, 1 for liver failure after hepatectomy for liver cancer, 1 for Wilson's disease, and 1 for chronic renal failure and liver cirrhosis. Retransplantation was done in 1 patient for chronic graft rejection. Of the 13 operations, 10 underwent the classical procedures of orthotopic liver transplantation, while 2 adopted modified piggyback technique, with 1 of the patients receiving retransplantation. RESULTS: Nine patients survived the transplantation with the longest survival over 2 years. Four patients died in the perioperative period, due to intracerebral bleeding, adult respiratory distress syndrome, acute renal failure and hepatic artery thrombus, respectively. CONCLUSIONS: Liver transplantation is an effective treatment for various end-stage liver diseases. Strict patient selection, appropriate timing of the operation and proper perioperative care are all essential for the success of liver transplantation.

[Postoperative complications after orthotopic liver transplantation: clinical analysis of 18 cases].

OBJECTIVE: To investigate experience in diagnosis and treatment of postoperative complications in patients undergoing orthotopic liver transplantation (OLT). METHODS: Complications, treatment and management following liver transplantation in 16 cases were analyzed retrospectively. RESULTS: Of 16 patients, 5 patients had advanced liver cirrhosis, 7 primary liver carcinoma, 1 liver failure after hepatectomy for liver cancer, 1 Wilson's disease, 1 chronic renal failure and liver cirrhosis and 1 acute live failure. Twelve patients survived, the longest survival was 4 years. Complications following OLT included: intra-abdominal bleeding in 3 cases, intracerebral vascular lesions in 2, pulmonary infection in 6, adult respiratory distress syndrome in 2, suprahepatic inferior vena caval occlusion in 2, hepatic artery thrombus in 1 case, bile duct stone or sludge in 3, bile leakage in 1 case, acute rejection in 2, chronic rejection in 2, acute renal failure in 2. Six patients died during perioperative period, one patient died of intracerebral bleeding, one from adult respiratory distress syndrome, one of acute renal failure one of hepatic artery thrombus, one of acute rejection and one of liver failure. CONCLUSIONS: Proper prevention and treatment can effectively reduce complications following OLT during perioperative period. The timely diagnosis, treatment and prophylactics are necessary to prevent these complications.

Hepatocellular Carcinoma Presenting with Obstructive Jaundice during Pregnancy.

Introduction. Both hepatocellular carcinoma (HCC) presenting during pregnancy and HCC presenting with obstructive jaundice due to a tumor cast in the biliary tract are very rare. The management of these patients remains challenging. Presentation of Case. A 23-year-old lady presented with obstructive jaundice at 38 weeks of gestation. Investigations showed HCC with a biliary tumor thrombus. She received percutaneous transhepatic biliary drainage (PTBD) and caesarean section. Right hepatectomy, extrahepatic bile duct resection, and left hepaticojejunostomy were carried out when the jaundice improved. The postoperative course was uneventful. She was discharged home on postoperative day 10. Histopathology showed HCC with a tumor thrombus in the bile duct. The surgical margins were clear. One year after surgery, the mother was disease-free and the baby was well. Conclusion. With proper management, curative treatment is possible in a pregnant patient who presented with obstructive jaundice due to a biliary tumor thrombus from HCC.

CXCL17 expression predicts poor prognosis and correlates with adverse immune infiltration in hepatocellular carcinoma.

CXC ligand 17 (CXCL17) is a novel CXC chemokine whose clinical significance remains largely unknown. In the present study, we characterized the prognostic value of CXCL17 in patients with hepatocellular carcinoma (HCC) and evaluated the association of CXCL17 with immune infiltration. We examined CXCL17 expression in 227 HCC tissue specimens by immunohistochemical staining, and correlated CXCL17 expression patterns with clinicopathological features, prognosis, and immune infiltrate density (CD4 T cells, CD8 T cells, B cells, natural killer cells, neutrophils, macrophages). Kaplan-Meier survival analysis showed that both increased intratumoral CXCL17 (P = 0.015 for overall survival [OS], P = 0.003 for recurrence-free survival [RFS]) and peritumoral CXCL17 (P = 0.002 for OS, P<0.001 for RFS) were associated with shorter OS and RFS. Patients in the CXCL17low group had significantly lower 5-year recurrence rate compared with patients in the CXCL17high group (peritumoral: 53.1% vs. 77.7%, P<0.001, intratumoral: 58.6% vs. 73.0%, P = 0.001, respectively). Multivariate Cox proportional hazards analysis identified peritumoral CXCL17 as an independent prognostic factor for both OS (hazard ratio [HR] = 2.066, 95% confidence interval [CI] = 1.296-3.292, P = 0.002) and RFS (HR = 1.844, 95% CI = 1.218-2.793, P = 0.004). Moreover, CXCL17 expression was associated with more CD68 and less CD4 cell infiltration (both P<0.05). The combination of CXCL17 density and immune infiltration could be used to further classify patients into subsets with different prognosis for RFS. Our results provide the first evidence that tumor-infiltrating CXCL17+ cell density is an independent prognostic factor that predicts both OS and RFS in HCC. CXCL17 production correlated with adverse immune infiltration and might be an important target for anti-HCC therapies.

Synchronous right hepatectomy and cesarean section in a pregnant lady with hepatocellular carcinoma.

INTRODUCTION: Cancer in pregnancy is rare and hepatocellular carcinoma (HCC) during pregnancy is even rarer. Due to limited experience, management of these patients remains challenging. PRESENTATION OF CASE: A 33-year old pregnant lady presented with HCC at 28 weeks of gestation. She underwent synchronous cesarean section and right hepatectomy at 32 weeks of gestation. The post-operative course was uneventful. She was discharged home on day 10 after surgery. Histolopathology confirmed HCC. The surgical resection margins were clear. At a follow-up of 3 months after surgery, the mother was disease free and the infant was well. DISCUSSION: HCC during pregnancy is extremely rare. The experience in its management and outcomes are lacking. In managing any patient diagnosed with a malignant neoplasm in pregnancy, both the mother and the fetus have to be considered. CONCLUSION: With adequate preoperative assessment and a good management strategy, good results can be obtained for both the mother and the baby for a pregnant patient with HCC.

Middle-preserving pancreatectomy for synchronous ampullary carcinoma and solid-pseudopapillary tumor of distal pancreas.

INTRODUCTION: Total pancreatectomy is the treatment of choice for multicentric diseases involving the pancreas. Middle-preserving pancreatectomy is a recently reported alternative procedure when the pancreatic body is spared from disease. PRESENTATION OF CASE: We report a 63-year old lady who underwent a combined Whipple's operation and distal splenopancreatectomy for her synchronous ampullary carcinoma and solid-pseudopapillary tumor of the distal pancreas. DISCUSSION: For multiple tumors of the pancreas, the choice of surgery should be based on the nature of pathology and follow the principle of oncological resection. CONCLUSION: Middle-preserving pancreatectomy is a safe and feasible option for patient with multicentric or synchronous pancreatic pathologies.
