ABSTRACT

Focal liver lesions are frequently encountered during imaging studies, and hemangiomas represent the most common solid liver lesion. Liver hemangiomas usually show characteristic imaging features that enable characterization without the need for biopsy or follow-up. On the other hand, there are many benign and malignant liver lesions that may show one or more imaging features resembling hemangiomas that radiologists must be aware of. In this article we will review the typical imaging features of liver hemangiomas and will show a series of potential liver hemangiomas' mimickers, giving radiologists some hints for improving differential diagnoses. CRITICAL RELEVANCE STATEMENT: The knowledge of imaging features of potential liver hemangiomas mimickers is fundamental to avoid misinterpretation. KEY POINTS: Liver hemangiomas typically show imaging features that enable avoiding a biopsy. Many benign and malignant liver lesions show imaging features resembling hemangiomas. Radiologists must know the potentially misleading imaging features of hemangiomas' mimickers.

ABSTRACT

BACKGROUND & AIMS: Frailty is associated with multiple morbidities. However, its effect on chronic liver diseases remains largely unexplored. This study evaluated the association of frailty with the risk of incident metabolic dysfunction-associated steatotic liver disease (MASLD), cirrhosis, liver cancer, and liver-related mortality. METHODS: A total of 339,298 participants without prior liver diseases from the UK Biobank were included. Baseline frailty was assessed by using physical frailty and the frailty index, categorizing participants as nonfrail, prefrail, or frail. The primary outcome was MASLD, with secondary outcomes, including cirrhosis, liver cancer, and liver-related mortality, confirmed through hospital admission records and death registries. RESULTS: During a median follow-up of 11.6 years, 4,667 MASLD, 1,636 cirrhosis, 257 liver cancer, and 646 liver-related mortality cases were identified. After multivariable adjustment, the risk of MASLD was found to be higher in participants with prefrailty (physical frailty: HR = 1.66, 95% CI = 1.40-1.97; frailty index: HR = 2.01, 95% CI = 1.67-2.42) and frailty (physical frailty: HR = 3.32, 95% CI = 2.54-4.34; frailty index: HR = 4.54, 95% CI = 3.65-5.66) than in those with nonfrailty. Similar results were also observed for cirrhosis, liver cancer, and liver-related mortality. Additionally, the frail groups had a higher risk of MASLD, which was defined as magnetic resonance imaging-derived liver proton density fat fraction > 5%, than the nonfrail group (physical frailty: OR = 1.64, 95% CI = 1.32-2.04; frailty index: OR = 1.48, 95% CI = 1.30-1.68). CONCLUSIONS: Frailty was associated with an increased risk of chronic liver diseases. Public health strategies should target reducing chronic liver disease risk in frail individuals. IMPACT AND IMPLICATIONS: While frailty is common and associated with a poor prognosis in people with MASLD and advanced chronic liver diseases, its impact on the subsequent risk of these outcomes remains largely unexplored. Our study showed that frailty was associated with the increased risks of MASLD, cirrhosis, liver cancer, and liver-related mortality. This finding suggests that assessing frailty may help identify a high-risk population vulnerable to developing chronic liver diseases. Implementing strategies that target frailty could have major public health benefits for liver-related disease prevention.

ABSTRACT

BACKGROUND: Selective internal radiation therapy (SIRT) with Yttrium-90 (Y90) has been historically reserved for unresectable liver malignancy. Evidence is emerging for the use of SIRT to increase future liver remnant (FLR), allowing for resection of previously inoperable disease. METHODS: Five-year retrospective review of all patients undergoing SIRT with Y90 at a tertiary institute. Patient demographics, clinicopathological data, surgical details and post-operative outcomes were reviewed. The primary outcome, safety of liver resection post-SIRT, was evaluated with 90-day morbidity and mortality. RESULTS: A total of 134 SIRT procedures were performed on 113 patients. Post-SIRT complications occurred in 18 (15.9%) patients, with a single 30-day mortality. Seventeen patients underwent SIRT with the intent to augment FLR for liver resection. Following SIRT, mean hepatic mebrofenin extraction and FLR rose from 2.5%/min/m2 and 30.5% to 4.2%/min/m2 (p=0.01) and 52.5% (p<0.0001), respectively. Ten patients underwent resection and there were two intra-operative complications. The median time from SIRT to resection was 5.2 months. Ninety-day post-operative morbidity was 20% (n=2) and complications were analysed according to the Clavien-Dindo II classification scale. There was no 30-day or 90-day post-operative mortality. CONCLUSION: Post-SIRT liver resection is a challenging procedure with low post-operative mortality and morbidity.

ABSTRACT

PURPOSE: Whether there are differences in recurrence-free survival (RFS) prognosis between combined hepatocellular carcinoma-cholangiocarcinoma (cHCC-CCA) cases with a small proportion of CCA components and HCC cases remains unknown. We aim to investigate the differences in RFS prognosis between cHCC-CCAs with a small proportion of CCA components and HCCs. METHODS: Patients with malignant liver neoplasms who underwent MRI and surgery were prospectively recruited. All cHCC-CCA patients were divided into different groups according to the ratio of CCA components. The primary end point was recurrence-free-survival. Cox regression analysis and Kaplan-Meier survival analysis was used to investigate and compare RFS prognosis. RESULTS: One hundred sixty-four cHCC-CCA cases and 271 HCC cases were enrolled. There was no significant difference in RFS prognosis between cHCC-CCA cases with a CCA component of < 10% and HCC cases (log rank p = 0.169). There were no significant differences in some major HCC-favoring MR features, such as nonrim APHE (85.7% vs. 81.5%, p = 0.546), nonperipheral washout (80.0% vs. 84.1%, p = 0.534), and enhancing capsule (62.9% vs. 45.4%, p = 0.051) between them. In addition, some clinicopathological findings had no significant differences between cHCC-CCAs with a CCA component of < 10% and HCCs (all p > 0.05). CONCLUSIONS: There were no significant differences in RFS prognosis, major HCC-favoring MRI features, and clinicopathological findings between cHCC-CCAs with a CCA component of < 10% and HCCs. Therefore, we suggest that cHCC-CCAs with pathological diagnosis of less than 10% of CCA components may be treated as HCCs in clinical setting.

ABSTRACT

AIMS: Structured reporting in pathology is not universally adopted and extracting elements essential to research often requires expensive and time-intensive manual curation. The accuracy and feasibility of using large language models (LLMs) to extract essential pathology elements, for cancer research is examined here. METHODS: Retrospective study of patients who underwent pathology sampling for suspected hepatocellular carcinoma and underwent Ytrrium-90 embolisation. Five pathology report elements of interest were included for evaluation. LLMs (Generative Pre-trained Transformer (GPT) 3.5 turbo and GPT-4) were used to extract elements of interest. For comparison, a rules-based, regular expressions (REGEX) approach was devised for extraction. Accuracy for each approach was calculated. RESULTS: 88 pathology reports were identified. LLMs and REGEX were both able to extract research elements with high accuracy (average 84.1%-94.8%). CONCLUSIONS: LLMs have significant potential to simplify the extraction of research elements from pathology reporting, and therefore, accelerate the pace of cancer research.

ABSTRACT

BACKGROUND: Stereotactic ablative body radiation (SABR) is a well-recognized treatment option for hepatocellular carcinoma (HCC). Due to the inherent motion of liver tumors, effective motion management is crucial for successful SABR. In the motion-encompassing motion management technique, all 10 respiratory phase image datasets are delineated and designated as the internal target volume (ITV). Some treatment centers use single or combination image sets to delineate the target volume. This study determines which specialty image set most closely matches an all-phase ITV contour on a synchronized contrast-enhanced 4DCT. MATERIALS AND METHODS: Synchronized 4DCT contrast and delayed scans were acquired for 10 patients in the study. The maximum intensity projection (MiP), average intensity projection (AvgIP), and minimum intensity projection (MinIP) images were generated. The ITV delineation was done in all 10 phases (ITV_all_phase). The ITV_2phase combines the peak inhale and exhale phase, ITV_2 M combines MiP and MinIP, and ITV_3 M combines MiP, MinIP, and AvgIP. All ITVs were compared to ITV_all_phase with Dice similarity index (DSI) and volumes. RESULTS: Using ITV_all_phase as the reference, the DSI and the mean ITV volumes for the different ITVs were as follows: ITV_all_phase (1 and 116.69 cc), ITV_2phase (0.87 and 105.27 cc), MiP (0.76 and 98.24 cc), AvgIP (0.72 and 94.54 cc), ITV_MinIP (0.67 and 81.08 cc), ITV_2 M (0.84 and 106.26 cc), and ITV_3 M (0.86 and 112.51 cc). CONCLUSION: The study demonstrates that in the motion-encompassing technique of motion management, the target volume generated by delineating all phases of 4DCT provides the most accurate representation for patients with HCC. Specialty image sets and their combinations, while sometimes close, tend to result in less accurate targeting. Hence, the all-phase 4DCT method should be preferred to avoid geographical misses and ensure optimal treatment outcomes. However, our conclusion may be limited by the technique we employed.

ABSTRACT

Purpose: To study the MRI features (based on LI-RADS) and clinical characteristics of P53-mutated hepatocellular carcinoma (HCC) patients. Patients and Methods: This study enrolled 344 patients with histopathologically confirmed HCC (P53-mutated group [n = 196], non-P53-mutated group [n = 148]). We retrospectively evaluated the preoperative MRI features, clinical and pathologic features of the lesions and assigned each lesion according to the LI-RADS. MRI findings, clinical features, and pathologic findings were compared using the Student's t test, χ2 test, and multivariable regression analysis. Results: Most HCC patients were categorized as LR-5. On multivariate analysis, the Edmondson-Steiner grade (odds ratio, 2.280; 95% CI: 1.268, 4.101; p = 0.006) and rim enhancement (odds ratio, 2.517; 95% CI: 1.095, 5.784; p = 0.030) were found to be independent variables associated with P53-mutated HCC. In the group of HCC lesions with the largest tumor diameter (LTD) greater than or equal to 10mm and less than or equal to 20mm, enhancing capsule was an independent predictor of P53-mutated HCC (odds ratio, 6.200; 95% CI: 1.116, 34.449; p = 0.037). Among the HCC lesions (20 mm ˂ LTD ≤ 50 mm), corona enhancement (odds ratio, 2.102; 95% CI: 1.022, 4.322; p = 0.043) and nodule-in-nodule architecture (odds ratio, 2.157; 95% CI: 1.033, 4.504; p = 0.041) were found to be independent risk factors for P53 mutation. Among the HCC lesions (50 mm ˂ LTD ≤ 100 mm), diameter (odds ratio, 1.035; 95% CI: 1.001, 1.069; p = 0.044) and AFP ≥ 400 (ng/mL) (odds ratio, 3.336; 95% CI: 1.052, 10.577; p = 0.041) were found to be independent variables associated with P53-mutated HCC. Conclusion: Poor differentiation and rim enhancement are potential predictive biomarkers for P53-mutated HCC, while HCCs of different diameters have different risk factors for predicting P53 mutations.

ABSTRACT

INTRODUCTION: Hepatectomies associated with vascular resections pose a technical challenge for surgeons, involving multiple reconstruction techniques. Moreover, adding clinical and surgical risks in the postoperative setting of these complex procedures are mainly due to prolonged surgical periods and potential complications inherent to vascular manipulation. Leveraging the expertise of a Cancer Center, we propose an institutional assessment utilizing the case series from A. C. Camargo Cancer Center in hepatectomies associated with vascular resection, evaluating postoperative complications and outcomes while highlighting clinical, laboratory, pathological, and surgical factors that may influence results. OBJECTIVE: To assess mortality and morbidity associated with hepatectomies involving vascular resection. MATERIALS AND METHODS: From a prospective database, a study was performed evaluating postoperative survival and morbidity using scoring systems such as Clavien-Dindo through a cohort analysis. RESULTS: From a total of 1021 liver resections for a period of 10 years, 31 cases were evaluated from a unique cancer center in Brazil! Factors such as the performance of major hepatectomies, the need for blood transfusion, and the administration of neoadjuvant or adjuvant systemic therapy did not appear to influence the outcome of morbidity or mortality. However, the resection of the associated bile duct and the type of vascular resection seemed to influence morbidity outcomes with statistical significance (p = 0.006+ …). CONCLUSION: Hepatectomies associated with vascular resections are safe in selected cases and when performed in referral centers. Factors such as associated bile duct resection and type of vascular resection should be considered for procedure indication.

ABSTRACT

Lymphoepithelioma-like intrahepatic cholangiocarcinoma (LEL-ICC) is a rare liver tumor that appears as a hepatic nodule on imaging with a specific pathological pattern, and the definitive diagnosis relies on its pathological histomorphology, immunophenotype, and Epstein-Barr encoding region test. Radical surgical resection is the primary treatment modality, and immunotherapy is expected to be a new adjuvant treatment option. LEL-ICC with massive multinucleated giant cell infiltration has not been reported so far. In this article, we report a patient with LEL-ICC showing massive multinucleated giant cell infiltration, review the relevant literature, and analyze its clinicopathological features and prognosis to accumulate experience for the accurate diagnosis of LEL-ICC.

ABSTRACT

OBJECTIVES: To create prediction models (PMs) for distinguishing between benign and malignant liver lesions using quantitative data from dual-energy CT (DECT) without contrast agents. MATERIALS AND METHODS: This retrospective study included patients with liver lesions who underwent DECT, including non-contrast-enhanced scans. Benign lesions included hepatic hemangioma, whereas malignant lesions included hepatocellular carcinoma, metastatic liver cancer, and intrahepatic cholangiocellular carcinoma. Patients were divided into derivation and validation groups. In the derivation group, two radiologists calculated ten multiparametric data using univariate and multivariate logistic regression to generate PMs. In the validation group, two additional radiologists measured the parameters to assess the diagnostic performance of PMs. RESULTS: The study included 121 consecutive patients (mean age 67.4 ± 13.8 years, 80 males), with 97 in the derivation group (25 benign and 72 malignant) and 24 in the validation group (7 benign and 17 malignant). Oversampling increased the benign lesion sample to 75, equalizing the malignant group for building PMs. All parameters were statistically significant in univariate analysis (all p < 0.05), leading to the creation of five PMs in multivariate analysis. The area under the curve for the five PMs of two observers was as follows: PM1 (slope K, blood) = 0.76, 0.74; PM2 (slope K, fat) = 0.55, 0.51; PM3 (effective-Z difference, blood) = 0.75, 0.72; PM4 (slope K, blood, fat) = 0.82, 0.78; and PM5 (slope K, effective-Z difference, blood) = 0.90, 0.87. PM5 yielded the best diagnostic performance. CONCLUSION: Multiparametric non-contrast-enhanced DECT is a highly effective method for distinguishing between liver lesions. CLINICAL RELEVANCE STATEMENT: The utilization of non-contrast-enhanced DECT is extremely useful for distinguishing between benign and malignant liver lesions. This approach enables physicians to plan better treatment strategies, alleviating concerns associated with contrast allergy, contrast-induced nephropathy, radiation exposure, and excessive medical expenses. KEY POINTS: Distinguishing benign from malignant liver lesions with non-contrast-enhanced CT would be desirable. This model, incorporating slope K, effective Z, and blood quantification, distinguished benign from malignant liver lesions. Non-contrast-enhanced DECT has benefits, particularly in patients with an iodine allergy, renal failure, or asthma.

ABSTRACT

Purpose: This study aimed to report the overall national trends in the rates of cancer screening based on recommendations and provide insights into the changing trends of these rates across different demographics. Materials and Methods: This study used data from the Korean National Cancer Screening Survey (KNCSS), which surveys nationwide cancer-screening rates and includes 4,500 individuals meeting the Korean National Cancer Screening Program (NCSP) protocol age criteria. Cancer-screening rates were assessed using structured questionnaires; yearly trends were analyzed for both lifetime cancer-screening rates and rates of screening based on recommendations, and subgroup analyses were performed based on age and sex. Results: The rates of cancer screening based on recommendations showed significant increments: the stomach cancer-screening rate increased from 39.2% in 2004 to 77.5% in 2023 (3.50% per year), the liver cancer-screening rate increased from 20.0% to 48.8% (4.30% per year), and the colorectal cancer, increased from 19.9% to 70.7% (5.15% per year). The breast cancer-screening rate increased from 33.2% to 72.7% (2.88% per year), and the cervical cancer, increased from 58.3% to 70.2% (1.08% per year). Despite some differences, particularly in relation to sociodemographic factors, screening rates increased significantly for all cancer types. Conclusion: Cancer-screening rates in Korea increased consistently from 2004 to 2023, demonstrating the effectiveness of the national cancer-screening program. However, the increments in breast, cervical and lung cancer-screening rates were relatively lower, indicating the need for additional efforts and strategies.

ABSTRACT

PURPOSE: To assess the association between minimal ablative margin (MAM) and local tumor progression (LTP) following CT-guided thermal ablation of colorectal liver metastases (CRLM) in a multicenter cohort and across two confirmation software. MATERIALS AND METHODS: This multicenter retrospective study included patients who underwent CT-guided radiofrequency or microwave ablation for CRLM between 2009 and 2021 in three institutions. Three-dimensional (3D) MAM was retrospectively assessed using dedicated ablation confirmation software by automatic non-rigid (Ablation-fit) or semi-automatic rigid co-registration (SAFIR) of intraprocedural pre- and post-ablation contrast-enhanced CT scans by two independent reader teams blinded to patient outcomes. LTP was assessed on a per-tumor basis. Factors associated with LTP-free survival were assessed using multivariable Cox regression analysis. RESULTS: Overall, 113 patients (mean age: 67 ± 10 years; 78 men) who underwent thermal ablation for 189 CRLM (mean diameter: 1.9 ± 1.1 cm) met the inclusion criteria. 173/189 (92%) CRLM could be successfully analyzed using both software. Over a median follow-up of 31 months (IQR: 22-47), 21 of 173 CRLM (12.1%) developed LTP. On multivariable analysis, 3D MAM was independently associated with LTP in both software (Ablation-fit: HR 0.47, 95% CI: 0.36-0.61, p < 0.001; SAFIR: HR 0.42, 95% CI: 0.32-0.55, p < 0.001). No LTP was observed in CRLM ablated with MAM ≥ 4 mm (Ablation-fit) and ≥ 5 mm (SAFIR). The per-tumor median absolute difference in MAM quantification between both software was 2 mm (IQR: 1-3). CONCLUSION: MAM was independently associated with LTP after thermal ablation of CRLM across multicenter data and two confirmation software. Ablations achieving a MAM ≥ 5 mm were associated with local control in both software. CLINICAL RELEVANCE STATEMENT: MAMs from intraprocedural contrast-enhanced CT were independently associated with LTP after thermal ablation of CRLM across multicenter data and two confirmation software, with a margin ≥ 5 mm associated with local control in both software. KEY POINTS: Sufficient ablative margins are critical for local control following thermal ablation of CRLM. Intraprocedural CT-derived MAM was the only independent factor associated with LTP across two confirmation software. No LTP was observed in CRLM ablated with a MAM ≥ 5 mm.

ABSTRACT

Background: It is well known that laparoscopic liver surgery can offer advantages over open liver surgery in selected patients. However, what type of procedures can benefit most from a laparoscopic approach has been investigated poorly thus far. The aim of this study is thus to define the extent of advantages of laparoscopic over open liver surgery for lesions in the anterolateral (AL) and posterosuperior (PS) segments. Methods: In this international multicentre retrospective cohort study, laparoscopic and open minor liver resections for lesions in the AL and PS segments were compared after propensity score matching. The differential benefit of laparoscopy over open liver surgery, calculated using bootstrap sampling, was compared between AL and PS resections and expressed as a Delta of the differences. Results: After matching, 3,040 AL and 2,336 PS resections were compared, encompassing open and laparoscopic procedures in a 1:1 ratio. AL and PS laparoscopic liver resections were more advantageous in comparison to open in terms of blood loss, transfusion rate, complications, and length of stay. However, AL resections benefitted more from laparoscopy than PS in terms of overall and severe complications (D-difference were 4.8%, P=0.046 and 3%, P=0.046) and blood loss (D-difference was 195 mL, P<0.001). Similar results were observed in the subset for high-volume centres, while in recent years no significant differences were found in the differential benefit between AL and PS segments. Conclusions: The advantage of laparoscopic over open liver surgery is greater in the AL segments than in the PS segments.

ABSTRACT

This study aimed to explore whether the prediagnostic use of metformin and statins is associated with the prognosis of patients with hepatocellular carcinoma (HCC) and type 2 diabetes. We identified 1383 eligible individuals who had both type 2 diabetes and HCC diagnosed between 1998 and 2017 from several Finnish registers. Cox models were fitted for cause-specific and all-cause mortality in relation to the use of antidiabetic medications and statins prior to the HCC diagnosis. Prediagnostic metformin use was associated with decreased overall mortality (hazard ratio 0.84, 95% confidence interval 0.74-0.94) compared with nonuse in patients with type 2 diabetes. Similarly, slightly decreased HCC mortality and other-cause mortality were observed among metformin users. The results were inconclusive regarding metformin use and both overall and HCC mortality among patients with localized HCC. No discernible contrast between statin users and nonusers was found in overall mortality nor HCC mortality in either the whole cohort or patients with localized cancer.

ABSTRACT

Introduction: This study aimed to investigate the liver-related outcomes of newly suggested metabolic dysfunction-associated steatotic liver disease (MASLD) and MASLD with increased alcohol intake (MetALD), as well as alcohol-associated liver disease (ALD). Methods: From a National Health Insurance Service Health Screening Cohort, we included 369,094 participants who underwent health checkups between 2009 and 2010 in South Korea. Steatotic liver disease (SLD) was defined as a fatty liver index ≥60. The risk of primary liver cancer (PLCa), hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (iCCA), incident cirrhosis, and decompensated cirrhosis was compared with no SLD. The subdistribution hazard ratio (SHR) was calculated using the Fine-Gray model regarding competing risks. Results: A total of 3,232 participants (0.9%) developed PLCa during the median follow-up of 3,227,176 person-years: 0.5% with no SLD, 1.1% with MASLD, 1.3% with MetALD, and 1.9% with ALD. Competing risk analysis revealed that compared with no SLD, MASLD (SHR: 1.65; 95% CI: 1.44-1.88), MetALD (SHR: 1.87; 95% CI: 1.52-2.29), and ALD (SHR: 1.86; 95% CI: 1.39-2.49) were associated with an increased risk of PLCa. MASLD (SHR: 1.96; 95% CI: 1.67-2.31), MetALD (SHR: 2.23; 95% CI: 1.75-2.84), and ALD (SHR: 2.34; 95% CI: 1.67-3.29) were associated with a higher risk of HCC. No significant difference was observed in the risk of iCCA. The risk of incident cirrhosis and decompensated cirrhosis increased in the order of no SLD, MASLD, MetALD, and ALD. Conclusion: MASLD, MetALD, and ALD have an increased risk of PLCa, HCC, incident cirrhosis, and decompensated cirrhosis but not iCCA. These findings may serve as a robust ground for the prognostic value of the newly suggested MASLD and MetALD.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Hepatocellular carcinoma (HCC) is an aggressive tumor and presents late. The underlying etiology of HCC is changing rapidly. HCC in Sri Lanka is unique due to its predominant non-viral etiology (nvHCC) but lacks survival data. METHOD: Data was collected from patients who presented with HCC from 2011 to 2018. There were 560/568 (98.6%) nvHCC. The patients who were not candidates for tumor-specific treatment (149/560 [26.7%]) were selected. Population characteristics, demographic data, tumor characteristics, survival and factors affecting survival were analyzed. RESULTS: The median age was 64 years (range 30-88) and 86% (n = 129) were males. As many as 124 (83%) were cirrhotic. The overall performance score was 80%. Nearly 21/124 tumors were detected in cirrhotic screening. Tumors were single nodular in 32 (21%), up to three nodules in 28 (18%), more than three nodules in 33 (22%) and diffusely infiltrating in 56 (37%). The major venous invasions were present in 78 (52.3%). Extra-hepatic tumor spread was seen in 19 (12.7%) (lungs 13 [72.2%], bones 2 [11.1%]). The median survival of patients receiving palliative care was three months (1-43 months). Tumor size and cirrhotic status were significant predictors in univariate analysis. CONCLUSION: A quarter of nvHCCs were not amenable to treatment at presentation as they had dismal survival. CLINICAL TRIAL REGISTRY NUMBER: P/126/09/2021.
