ABSTRACT
BACKGROUND: Liver stiffness (LS) measurement with two-dimensional shear wave elastography (2D-SWE) correlates with the degree of liver fibrosis and thus indirectly reflects liver function reserve. The size of the spleen increases due to tissue proliferation, fibrosis, and portal vein congestion, which can indirectly reflect the situation of liver fibrosis/cirrhosis. It was reported that the size of the spleen was related to posthepatectomy liver failure (PHLF). So far, there has been no study combining 2D-SWE measurements of LS with spleen size to predict PHLF. This prospective study aimed to investigate the utility of 2D-SWE assessing LS and spleen area (SPA) for the prediction of PHLF in hepatocellular carcinoma (HCC) patients and to develop a risk prediction model. AIM: To investigate the utility of 2D-SWE assessing LS and SPA for the prediction of PHLF in HCC patients and to develop a risk prediction model. METHODS: This was a multicenter observational study prospectively analyzing patients who underwent hepatectomy from October 2020 to March 2022. Within 1 wk before partial hepatectomy, ultrasound examination was performed to measure LS and SPA, and blood was drawn to evaluate the patient's liver function and other conditions. Least absolute shrinkage and selection operator logistic regression and multivariate logistic regression analysis was applied to identify independent predictors of PHLF and develop a nomogram. Nomogram performance was validated further. The diagnostic performance of the nomogram was evaluated with receiver operating characteristic curve compared with the conventional models, including the model for end-stage liver disease (MELD) score and the albumin-bilirubin (ALBI) score. RESULTS: A total of 562 HCC patients undergoing hepatectomy (500 in the training cohort and 62 in the validation cohort) were enrolled in this study. The independent predictors of PHLF were LS, SPA, range of resection, blood loss, international normalized ratio, and total bilirubin. Better diagnostic performance of the nomogram was obtained in the training [area under receiver operating characteristic curve (AUC): 0.833; 95% confidence interval (95%CI): 0.792-0.873; sensitivity: 83.1%; specificity: 73.5%] and validation (AUC: 0.802; 95%CI: 0.684-0.920; sensitivity: 95.5%; specificity: 52.5%) cohorts compared with the MELD score and the ALBI score. CONCLUSION: This PHLF nomogram, mainly based on LS by 2D-SWE and SPA, was useful in predicting PHLF in HCC patients and presented better than MELD score and ALBI score.

BACKGROUND: Validating the expanded criteria for living donor liver transplantation for hepatocellular carcinoma using national data is highly significant. The aim of this study was to evaluate the validity of the new Japanese criteria for living donor liver transplantation for hepatocellular carcinoma patients and identify factors associated with a poor prognosis using the Japanese national data set. METHODS: The study population comprised patients who underwent living donor liver transplantation for hepatocellular carcinoma at 37 centres in Japan between 2010 and 2018. In a nationwide survey, the overall survival and recurrence-free survival rates were evaluated based on the new Japanese criteria for applying the 5-5-500 rule when extending the indication beyond the Milan criteria. Prognostic factors within the Japanese criteria were determined using the Cox proportional hazards model. RESULTS: Patients within (485 patients) and beyond (31 patients) the Japanese criteria exhibited 5-year overall survival rates of 81% and 58% and 5-year recurrence-free survival rates of 77% and 48% respectively. Patients who met the Milan criteria, but not the 5-5-500 rule, had poorer outcomes. Multivariate analysis for 474 patients identified a neutrophil-to-lymphocyte ratio greater than or equal to 5 and a history of hepatectomy as independent risk factors. CONCLUSION: This nationwide survey confirms the validity of the Japanese criteria. The poor prognostic factors within the Japanese criteria include a neutrophil-to-lymphocyte ratio greater than or equal to 5 and previous hepatectomy.

BACKGROUND: Surgical resection remains the cornerstone of treatment for hepatoblastoma in children and offers the best chance of disease-free survival. We aimed to analyze the 30 day outcomes of hepatic resection for hepatoblastoma stratified by extent using the National Surgical Quality Improvement Program-Pediatric (NSQIP-P). METHODS: We queried NSQIP-P for children undergoing resection of Hepatoblastoma from 2012 to 2021. Relevant clinical characteristics and outcomes were extracted for multivariate logistic regression to identify predictors of common adverse outcomes. RESULTS: We included 458 children with a median age of 1.90 years. Overall complications were rare, and perioperative blood transfusion (64.2%) and postoperative ventilation > 48 h (10.0%) were the only adverse events prevalent in more than 5% of patients. Median transfusion volume was 15.7 ml/kg. On multivariate regression, only patients undergoing Trisectionectomy (aOR = 3.387, 95% C.I. = 1.348-8.510) had higher odds of receiving > 75th percentile blood transfusion. Furthermore, only perioperative transfusion and postoperative ventilation > 48 h were statistically more common in patients undergoing extended versus standard resections. CONCLUSIONS: Outcomes following resection of hepatoblastoma are excellent, with low rates of postoperative adverse events. Although children undergoing trisectionectomy likely require greater transfusion volume, extended hepatic resections do not appear to have worse 30 day outcomes despite greater operative complexity and duration.

Gender-specific differences in hepatobiliary and transplantation surgery are decisive for the diagnosis, treatment and long-term outcomes. Men exhibit a higher risk of late recurrences and cancer-specific death after liver cancer resection. The emphasis on screening recommendations and ensuring equal access to treatment options are vital to minimize disparities. In kidney and liver transplantations, women are less frequently listed and endure longer waiting times, while men dominate the waiting list. Gender-specific disparities in drug compatibility necessitate differentiated dosing. Further studies are needed to ensure equity in transplantation treatment. Individualized treatment considering these differences can enhance treatment outcomes and the quality of life of patients.

PURPOSE: Hepatic metastasis frequently occurs in patients who have undergone radical pancreatic resection for pancreatic cancer. Besides chemotherapy, various local treatment approaches targeting hepatic lesions have been explored. However, research on radiofrequency ablation (RFA) as a localized therapy for hepatic metastasis is limited. Therefore, we conducted this retrospective study to provide clinical evidence. METHODS: This is a single-center, retrospective, cohort study. After radical pancreaticoduodenectomy, 32 patients developed metachronous hepatic metastasis with fewer than 3 lesions, the largest of which was less than 3 cm in diameter. These patients underwent combined treatment with chemotherapy and RFA. After 8 weeks of chemotherapy, patients received RFA for hepatic lesions. Additional chemotherapy was administered, and the patients' tumor status and survival were monitored. The primary endpoint of this study was overall survival (OS). Factors affecting OS were analyzed using the Cox risk model. RESULTS: Among the 32 patients, the mean OS was 28.4 months. Univariate and multivariate Cox regression analysis revealed that the time (in months) of liver metastasis (HR = 0.04, 95% CI: 0.01 to 0.19; P < 0.001), the number of liver metastases (HR = 7.08, 95% CI: 1.85 to 27.08, P = 0.004), and PD (progressive disease) response to the second round of chemotherapy (HR = 29.50, 95% CI: 1.46 to 597.27; P = 0.027) were independent predictors of poorer survival. CONCLUSION: Combined therapy with RFA and chemotherapy is safe in patients with hepatic metastasis after radical pancreaticoduodenectomy. Early recurrence (≤12 months), three liver metastatic lesions, and a poor response to the second round of chemotherapy were associated with poor survival.

BACKGROUND: In this study, we aimed to establish nomograms to predict the microvascular invasion (MVI) and early recurrence in patients with small hepatocellular carcinoma (SHCC), thereby guiding individualized treatment strategies for prognosis improvement. METHODS: This study retrospectively analyzed 326 SHCC patients who underwent radical resection at Wuhan Union Hospital between April 2017 and January 2022. They were randomly divided into a training set and a validation set at a 7:3 ratio. The preoperative nomogram for MVI was constructed based on univariate and multivariate logistic regression analysis, and the prognostic nomogram for early recurrence was constructed based on univariate and multivariate Cox regression analysis. We used the receiver operating characteristic (ROC) curves, area under the curves (AUCs), and calibration curves to estimate the predictive accuracy and discriminability of nomograms. Decision curve analysis (DCA) and Kaplan-Meier survival curves were employed to further confirm the clinical effectiveness of nomograms. RESULTS: The AUCs of the preoperative nomogram for MVI on the training set and validation set were 0.749 (95%CI: 0.684-0.813) and 0.856 (95%CI: 0.805-0.906), respectively. For the prognostic nomogram, the AUCs of 1-year and 2-year RFS respectively reached 0.839 (95%CI: 0.775-0.903) and 0.856 (95%CI: 0.806-0.905) in the training set, and 0.808 (95%CI: 0.719-0.896) and 0.874 (95%CI: 0.804-0.943) in the validation set. Subsequent calibration curves, DCA analysis and Kaplan-Meier survival curves demonstrated the high accuracy and efficacy of the nomograms for clinical application. CONCLUSIONS: The nomograms we constructed could effectively predict MVI and early recurrence in SHCC patients, providing a basis for clinical decision-making.

PURPOSE: Single large hepatocellular carcinoma >5cm (SLHCC) traditionally requires a major liver resection. Minor resections are often performed with the goal to reduce morbidity and mortality. Aim of the study was to establish if a major resection should be considered the best treatment for SLHCC or a more limited resection should be preferred. METHODS: A multicenter retrospective analysis of the HE.RC.O.LE.S. Group register was performed. All collected patients with surgically treated SLHCC were divided in 5 groups of treatment (major hepatectomy, sectorectomy, left lateral sectionectomy, segmentectomy, non-anatomical resection) and compared for baseline characteristics, short and long-term results. A propensity-score weighted analysis was performed. RESULTS: 535 patients were enrolled in the study. Major resection was associated with significantly increased major complications compared to left lateral sectionanectomy, segmentectomy and non-anatomical resection (all p<0.05) and borderline significant increased major complications compared to sectorectomy (p=0.08). Left lateral sectionectomy showed better overall survival compared to major resection (p=0.02), while other groups of treatment resulted similar to major hepatectomy group for the same item. Absence of oncological benefit after major resection and similar outcomes among the 5 groups of treatment was confirmed even in the sub-population excluding patients with macrovascular invasion. CONCLUSION: Major resection was associated to increased major post-operative morbidity without long-term survival benefit; when technically feasible and oncologically adequate, minor resections should be preferred for the surgical treatment of SLHCC.

BACKGROUND: To explore the capability of diffusion-based virtual MR elastography (vMRE) in the preoperative prediction of recurrence in hepatocellular carcinoma (HCC) and to investigate the underlying relevant histopathological characteristics. METHODS: Between August 2015 and December 2016, patients underwent preoperative MRI examination with a dedicated DWI sequence (b-values: 200,1500 s/mm2) were recruited. The ADC values and diffusion-based virtual shear modulus (µdiff) of HCCs were calculated and MR morphological features were also analyzed. The Cox proportional hazards model was used to identify the risk factors associated with tumor recurrence. A preoperative radiologic model and postoperative model including pathological features were built to predict tumor recurrence after hepatectomy. RESULTS: A total of 87 patients with solitary surgically confirmed HCCs were included in this study. Thirty-five patients (40.2%) were found to have tumor recurrence after hepatectomy. The preoperative model included higher µdiff and corona enhancement, while the postoperative model included higher µdiff, microvascular invasion, and histologic tumor grade. These factors were identified as significant prognostic factors for recurrence-free survival (RFS) (all p < 0.05). The HCC patients with µdiff values > 2.325 kPa showed poorer 5-year RFS after hepatectomy than patients with µdiff values ≤ 2.325 kPa (p < 0.001). Moreover, the higher µdiff values was correlated with the expression of CK19 (3.95 ± 2.37 vs. 3.15 ± 1.77, p = 0.017) and high Ki-67 labeling index (4.22 ± 1.63 vs. 2.72 ± 2.12, p = 0.001). CONCLUSIONS: The µdiff values related to the expression of CK19 and Ki-67 labeling index potentially predict RFS after hepatectomy in HCC patients.

OBJECTIVE: To assess the independent and combined associations of tumor-related psychiatric symptoms (TRPS) with dynamic health-related quality of life (HRQL) in patients with hepatocellular carcinoma (HCC) after hepatectomy and to identify related patterns of health behaviors. METHODS: This prospective study included patients with HCC who underwent hepatectomy between September 2021 and May 2022. Independent and combined associations between TRPS and HRQL were identified by generalized linear model and weighted quantile sum model, respectively. Trajectories of HRQL were identified by latent class mixed model. RESULTS: Among the 205 patients, 174 (84.9%) were male. For the outcome of HRQL at 6 months: Anxiety, depression, fatigue, and sleep disorder were independently associated with a decrease of HRQL (all P < 0.05). A negative combined effect of TRPS was also found (ß = - 5.07, 95% CI, - 10.01 to - 0.13), with depression emerged as the predominant contributor (49%). The health behaviors of body mass index, smoking, drinking, or physical exercise were not significantly modified the associations between combined TRPS and HRQL (all P > 0.05 for interaction). Similar results were also found for the HRQL at baseline and at 1 and 3 months. Three HRQL trajectory groups were identified: recover (44.9%), poor (44.4%), and deteriorating (10.7%). Deteriorating group was associated with higher incidence of TRPS (all P < 0.05). CONCLUSIONS: TRPS were associated with a decrease of HRQL regardless of healthy behaviors in HCC patients. Therefore, healthy behaviors promotion alone might not substantially increase HRQL associated with TRPS, and other measures tackling TRPS are warranted.

BACKGROUND: Postoperative liver metastasis significantly impacts the prognosis of pancreatic neuroendocrine tumor (panNET) patients after R0 resection. Combining computational pathology and deep learning radiomics can enhance the detection of postoperative liver metastasis in panNET patients. METHODS: Clinical data, pathology slides, and radiographic images were collected from 163 panNET patients post-R0 resection at Fudan University Shanghai Cancer Center (FUSCC) and FUSCC Pathology Consultation Center. Digital image analysis and deep learning identified liver metastasis-related features in Ki67-stained whole slide images (WSIs) and enhanced CT scans to create a nomogram. The model's performance was validated in both internal and external test cohorts. RESULTS: Multivariate logistic regression identified nerve infiltration as an independent risk factor for liver metastasis (p < 0.05). The Pathomics score, which was based on a hotspot and the heterogeneous distribution of Ki67 staining, showed improved predictive accuracy for liver metastasis (AUC = 0.799). The deep learning-radiomics (DLR) score achieved an AUC of 0.875. The integrated nomogram, which combines clinical, pathological, and imaging features, demonstrated outstanding performance, with an AUC of 0.985 in the training cohort and 0.961 in the validation cohort. High-risk group had a median recurrence-free survival of 28.5 months compared to 34.7 months for the low-risk group, showing significant correlation with prognosis (p < 0.05). CONCLUSION: A new predictive model that integrates computational pathologic scores and deep learning-radiomics can better predict postoperative liver metastasis in panNET patients, aiding clinicians in developing personalized treatments.

Radiofrequency ablation (RFA) offers a minimally invasive treatment for small hepatocellular carcinoma (HCC), but it faces challenges such as high local recurrence rates. This prospective study, conducted from January 2020 to July 2022, evaluated a novel approach using a three-channel, dual radiofrequency (RF) generator with separable clustered electrodes to improve RFA's efficacy and safety. The study employed a high-power, gradual, stepwise RFA method on HCCs (≤ 4 cm), utilizing real-time ultrasound-computed tomography (CT)/magnetic resonance imaging (MRI) fusion imaging. Involving 110 participants with 116 HCCs, the study reported no major complications. Local tumor progression (LTP) and intrahepatic remote recurrence (IRR) rates were low, with promising cumulative incidences at 1, 2, and 3 years for LTP (0.9%, 3.6%, 7.0%) and IRR (13.9%, 20.5%, 31.4%). Recurrence-free survival (RFS) rates were similarly encouraging: LTP (99.1%, 96.4%, 93.0%) and IRR (86.1%, 79.5%, 68.6%). This innovative gradual, incremental high-power RFA technique, featuring a dual switching monopolar mode and three electrodes, represents an effective and safer management option for small HCCs.

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.

INTRODUCTION: Survival comparisons among patients with liver metastases from pancreatic and rectal neuroendocrine tumors (NETs) were limited, and the efficacy of observation rules in patients undergoing hepatectomy for neuroendocrine liver metastases (NELMs) was unknown. This study aims to distinguish these characteristics and clarify the effects of the observation rules on NELMs. METHODS: Clinical data were separately collected from patients with pancreatic and rectal NELMs at medical centers in both Japan and China. The Japanese cohort followed the observation rules for the resection of NELMs. A comparative analysis was conducted on clinical characteristics and prognosis features such as overall survival time (OS) and disease-free survival interval (DFS-I). RESULTS: Enrollment included 47 and 34 patients from Japan and China, respectively. Of these, 69 and 12 patients had tumors originating from the pancreas and rectum, respectively. The OS time in patients undergoing primary tumor resection was significantly longer; however, the OS time between the patients undergoing and not undergoing radical resection of liver metastasis was the same. In asynchronous NELMs, patients with rectal (R)-NELMs showed a significantly higher proportion of type III NELMs. Additionally, the median DFS-I of asynchronous R-NELMs was longer than the recommended follow-up time, with 71.4% of them classified as G2. In the Japanese cohort, patients who adhered to the observation rules exhibited a longer median DFS after hepatectomy for NELMs compared with their counterparts. CONCLUSION: Although curative surgery is crucial for primary lesions, personalized approaches are required to manage NELMs. Extended overall follow-ups and shortened follow-up intervals are recommended for G2 stage rectal NETs. The observation rules for NELMs require further validation with a larger sample size.

BACKGROUND: In China, both percutaneous microwave/radiofrequency ablation liver partition plus portal vein embolization (PALPP) and transarterial chemoembolization (TACE) plus portal vein embolization (PVE) have been utilized in planned hepatectomy. However, there is a lack of comparative studies on the effectiveness of these two techniques for cases with insufficient future liver remnant (FLR). METHODS: Patients were categorized into either the PALPP group or the TACE + PVE group. Clinical data, including FLR growth rate, complications, secondary resection rate, and overall survival rate, were compared and analyzed for both groups retrospectively. RESULTS: Between December 2014 and October 2021, a total of 29 patients underwent TACE + PVE (n = 12) and PALPP (n = 17). In the TACE + PVE group, 7 patients successfully underwent two-stage hepatectomy, while in the PALPP group, 13 patients underwent the procedure (two-stage resection rate: 58.3% vs. 76.5%, P = 0.42). There were no significant differences in postoperative complications of one-stage procedures (11.8% vs. 8.3%, P > 0.05) and second-stage resection complication (0% vs. 46.2%, P = 0.05) between the TACE + PVE and PALPP groups. However, the PALPP group demonstrated a shorter time to FLR volume growth for second-stage resection (18.5 days vs. 66 days, P = 0.001) and KGR (58.5 ml/week vs. 7.7 ml/week, P = 0.001). CONCLUSIONS: Compared with TACE + PVE, PALPP results in a more significant increase in FLR volume and a higher rate of two-stage resection without increasing postoperative complications.

INTRODUCTION: Hepatocellular carcinoma (HCC) is the most common primary liver cancer and the third leading cause of cancer-related deaths worldwide. Hepatic resection is the treatment of choice for non-cirrhotic patients, while in cirrhotic individuals, the choice depends on tumor stage and liver function. METHODS: In this retrospective study conducted at Hospital El Cruce between 2015 and 2022, patients with HCC undergoing hepatic resection, both cirrhotic and non-cirrhotic, were evaluated. Morbidity, mortality, recurrence rate, and survival were analyzed. RESULTS: A total of 262 hepatectomies were performed, with 44 for HCC treatment. Among them, 35 were minor hepatectomies, and 9 were major hepatectomies (noncirrhotic patients). The majority were males (77%) with an average age of 58.5 years. Twenty-nine patients had cirrhosis, with hepatitis C (HCV) being the main cause in 48%, HCV with alcohol as a cofactor (21%), and alcohol alone (17%). Morbidity was 47.7%, with predominance of minor complications. Disease recurrence occurred in 59% of patients, and associated factors included tumor size and elevated AFP levels. Survival was better in cirrhotic patients compared to non-cirrhotic ones. DISCUSSION: Results tion 5837 Hepatic resection is an effective option for treating HCC in well-selected cirrhotic and non-cirrhotic patients, with encouraging results in terms of survival and disease control. Additionally, close surveillance for early recurrence detection and timely interventions is suggested.

La resección hepática es el tratamiento de elección para pacientes no cirróticos, mientras que, en cirróticos, la elección depende del estadio tumoral y la función hepática. Métodos: En este estudio retrospectivo realizado en el Hospital El Cruce entre 2015 y 2022, se evaluaron pacientes con HCC sometidos a resección hepática, tanto cirróticos como no cirróticos. Se analizó la morbimortalidad, la tasa de recurrencia y la sobrevida. Resultados: Se realizaron 262 hepatectomías, 44 fueron para tratamiento del HCC, de las cuales 35 fueron hepatectomías menores, y 9 hepatectomías mayores (no cirróticos). La mayoría eran hombres (77%) con una edad promedio de 58.5 años. Hubo 29 pacientes con cirrosis, siendo la hepatitis C (HCV) la causa principal en un 48%, HCV con alcohol como cofactor (21%) y alcohol (17%). La morbilidad fue del 47.7%, con complicaciones menores predominantes. La recurrencia de enfermedad ocurrió en el 59% de los pacientes, y los factores asociados incluyeron tamaño tumoral y niveles elevados de Alfafetoproteína. La supervivencia fue mejor en pacientes cirróticos en comparación con no cirróticos. Conclusión: La resección hepática es una opción efectiva para el tratamiento del HCC en pacientes bien seleccionados cirróticos y no cirróticos, con resultados alentadores en términos de supervivencia y control de la enfermedad. Además, se sugiere una vigilancia cercana para detectar recurrencias tempranas y proporcionar tratamientos oportunos.
