RESUMO
PURPOSE: The technical difficulties of laparoscopic liver resection (LLR) are greatly associated with the location of liver tumors. Since segment 8 (S8) contains a wide area, the difficulty of LLR for S8 tumors may vary depending on the location within the segment, such as the ventral (S8v) and dorsal (S8d) area, but the difference is unclear. METHODS: We retrospectively investigated 30 patients who underwent primary laparoscopic partial liver resection for liver tumors in S8 at Kobe University Hospital between January 2018 and June 2023. RESULTS: Thirteen and 17 patients underwent LLR for S8v and S8d, respectively. The operation time was significantly longer (S8v 203[135-259] vs. S8d 261[186-415] min, P = 0.002) and the amount of blood loss was significantly higher (10[10-150] vs. 10[10-200] mL, P = 0.034) in the S8d group than in the S8v group. No significant differences were observed in postoperative complications or postoperative length of hospital stay. Additionally, intraoperative findings revealed that the rate at which the case performed partial liver mobilization in the S8d group was higher (2[15.4%] vs. 8[47.1%], P = 0.060) and the median parenchymal transection time of the S8d group was longer (102[27-148] vs. 129[37-175] min, P = 0.097) than those in the S8v group, but there were no significant differences. CONCLUSION: The safety of LLR for the S8d was comparable to that of LLR for S8v, although LLR for S8d resulted in longer operative time and more blood loss. THE TRIAL REGISTRATION NUMBER: B230165 (approved at December 26, 2023).

PURPOSE: The impact of postoperative bile leak on the prognosis of patients with hepatocellular carcinoma who underwent liver resection is controversial. This study aimed to investigate the prognostic impact of bile leak for patients with hepatocellular carcinoma who underwent liver resection. METHODS: Patients with hepatocellular carcinoma who underwent liver resection between 2009 and 2019 at Kobe University Hospital and Hyogo Cancer Center were included. After propensity score matching between the bile leak and no bile leak groups, differences in 5-year recurrence-free and overall survival rates were evaluated using the Kaplan-Meier method. RESULTS: A total of 781 patients, including 43 with postoperative bile leak, were analyzed. In the matched cohort, 40 patients were included in each group. The 5-year recurrence-free survival rates after liver resection were 35% and 32% for the bile leak and no bile leak groups, respectively (P = 0.857). The 5-year overall survival rates were 44% and 54% for the bile leak and no bile leak groups, respectively (P = 0.216). CONCLUSION: Overall, bile leak may not have a profound negative impact on the prognosis of patients with hepatocellular carcinoma who have undergone liver resection.

Tremelimumab plus durvalumab (Dur/Tre) is the first-line treatment for advanced hepatocellular carcinoma (HCC) worldwide. The present report describes the case of a 68-year-old man diagnosed with advanced HCC and a bile duct tumor thrombus (BDTT) who achieved a complete response to Dur/Tre therapy. The BDTT progressed to the bifurcation of the left and right hepatic ducts. Over time, both the tumors and BDTT progressively decreased in size, and a complete response was confirmed using the Response Evaluation Criteria in Solid Tumors (version 1.1.) 6 months after treatment administration. Subsequently, immune-related adverse events, including type 1 diabetes mellitus and diabetic ketoacidosis, emerged, leading to treatment discontinuation. The patient was undergoing outpatient follow-up in a drug-free state with no signs of recurrence 290 days after the initial administration of Dur/Tre. Although long-term and meticulous observations are required, the present findings could influence the choice of systemic chemotherapy for advanced HCC.
RESUMO
BACKGROUND/AIM: The treatment algorithm for systemic therapies for advanced hepatocellular carcinoma (HCC) has changed dramatically; however, the therapeutic landscape for sequential second-line or later-line treatments, including ramucirumab, remains controversial. This study aimed to investigate the role of ramucirumab for treating HCC. PATIENTS AND METHODS: We retrospectively analyzed data from 17 patients with advanced HCC who received ramucirumab, and 8 of them who received lenvatinib re-administration after ramucirumab treatment failure. RESULTS: The median overall survival of 17 patients treated with ramucirumab was 11.5 months. The median ratios of the 1-month post-treatment α-fetoprotein (AFP) levels and albumin-bilirubin (ALBI) scores to the pre-treatment AFP levels and ALBI scores following ramucirumab treatment were 0.880 and 0.965, respectively. The median ratios of the 1-month post-treatment AFP and ALBI levels to the pre-treatment levels were 1.587 and 0.970 for mALBI grade 1/2a, and 1.313 and 0.936 for mALBI grade 2b/3, respectively. Six of the eight patients who received lenvatinib rechallenge treatment exhibited a decrease in AFP levels one month post-lenvatinib treatment. Deterioration of liver function 3 months post-lenvatinib treatment was noted in five of the eight patients who received lenvatinib rechallenge treatment after ramucirumab. CONCLUSION: Ramucirumab may be equally useful in patients with unresectable HCC who have poor liver function or whose liver function is aggravated by other therapies. Rechallenge treatment with lenvatinib after ramucirumab may be a valid treatment option for HCC.

BACKGROUND/AIM: This study aimed to evaluate the utility of the albumin-bilirubin grade for predicting the prognosis after repeat liver resection for patients with recurrent hepatocellular carcinoma. PATIENTS AND METHODS: Ninety patients with intrahepatic recurrent hepatocellular carcinoma who underwent repeat liver resection at our institution between 2005 and 2019 were retrospectively analyzed. Cox proportional-hazards regression models evaluated independent preoperative prognostic factors, including the albumin-bilirubin grade. Prognosis differences between patients with albumin-bilirubin grades 1 and 2 were analyzed using the Kaplan-Meier method. RESULTS: Cox proportional-hazards regression analysis revealed that albumin-bilirubin grade 2 (p=0.003) and early recurrence within one year from the initial surgery (p=0.001) were independently associated with poor recurrence-free survival, and albumin-bilirubin grade 2 (p=0.020) was independently associated with poor overall survival. The five-year recurrence-free (31% and 17%, respectively) and overall (86% and 60%, respectively) survival rates after repeat liver resection for patients with albumin-bilirubin grades 1 and 2 were significantly different between groups (both p=0.003). CONCLUSION: The albumin-bilirubin grade is useful for preoperatively predicting favorable survival rates after repeat liver resection for patients with recurrent hepatocellular carcinoma. Patients with an albumin-bilirubin grade 1 are better candidates for surgical treatment of recurrent hepatocellular carcinoma.

BACKGROUND: Drainage fluid amylase (DFA) is useful for predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP). However, difference in optimal cutoff value of DFA for predicting CR-POPF between open DP (ODP) and laparoscopic DP (LDP) has not been investigated. This study aimed to identify the optimal cutoff values of DFA for predicting CR-POPF after ODP and LDP. METHODS: Data for 294 patients (ODP, n = 127; LDP, n = 167) undergoing DP at Kobe University Hospital between 2010 and 2021 were reviewed. Propensity score matching was performed to minimize treatment selection bias. Receiver operating characteristic (ROC) analysis was performed to determine the optimal cutoff values of DFA for predicting CR-POPF for ODP and LDP. Logistic regression analysis for CR-POPF was performed to investigate the diagnostic value of DFA on postoperative day (POD) three with identified cutoff value. RESULTS: In the matched cohort, CR-POPF rates were 24.7% and 7.9% after ODP and LDP, respectively. DFA on POD one was significantly lower after ODP than after LDP (2263 U/L vs 4243 U/L, p < 0.001), while the difference was not significant on POD three (543 U/L vs 1221 U/L, p = 0.171). ROC analysis revealed that the optimal cutoff value of DFA on POD one and three for predicting CR-POPF were different between ODP and LDP (ODP, 3697 U/L on POD one, 1114 U/L on POD three; LDP, 10564 U/L on POD one, 6020 U/L on POD three). Multivariate analysis showed that DFA on POD three with identified cutoff value was the independent predictor for CR-POPF both for ODP and LDP. CONCLUSIONS: DFA on POD three is an independent predictor for CR-POPF after both ODP and LDP. However, the optimal cutoff value for it is significantly higher after LDP than after ODP. Optimal threshold of DFA for drain removal may be different between ODP and LDP.

BACKGROUND: Venous thromboembolism (VTE) is a potentially fatal complication of hepatectomy. The use of postoperative prophylactic anticoagulation in patients who have undergone hepatectomy is controversial because of the risk of postoperative bleeding. Therefore, we hypothesized that monitoring plasma D-dimer could be useful in the early diagnosis of VTE after hepatectomy. AIM: To evaluate the utility of monitoring plasma D-dimer levels in the early diagnosis of VTE after hepatectomy. METHODS: The medical records of patients who underwent hepatectomy at our institution between January 2017 and December 2020 were retrospectively analyzed. Patients were divided into two groups according to whether or not they developed VTE after hepatectomy, as diagnosed by contrast-enhanced computed tomography and/or ultrasonography of the lower extremities. Clinicopathological factors, including demographic data and perioperative D-dimer values, were compared between the two groups. Receiver operating characteristic curve analysis was performed to determine the D-dimer cutoff value. Univariate and multivariate analyses were performed using logistic regression analysis to identify significant predictors. RESULTS: In total, 234 patients who underwent hepatectomy were, of whom (5.6%) were diagnosed with VTE following hepatectomy. A comparison between the two groups showed significant differences in operative time (529 vs 403 min, P = 0.0274) and blood loss (530 vs 138 mL, P = 0.0067). The D-dimer levels on postoperative days (POD) 1, 3, 5, 7 were significantly higher in the VTE group than in the non-VTE group. In the multivariate analysis, intraoperative blood loss of > 275 mL [odds ratio (OR) = 5.32, 95% confidence interval (CI): 1.05-27.0, P = 0.044] and plasma D-dimer levels on POD 5 ≥ 21 µg/mL (OR = 10.1, 95%CI: 2.04-50.1, P = 0.0046) were independent risk factors for VTE after hepatectomy. CONCLUSION: Monitoring of plasma D-dimer levels after hepatectomy is useful for early diagnosis of VTE and may avoid routine prophylactic anticoagulation in the postoperative period.
