BACKGROUND AND OBJECTIVE

Transarterial chemoembolization (TACE) is a locoregional therapy used in patients with unresectable intermediate-stage hepatocellular carcinoma (HCC). It has proven benefit on overall survival, but considerable side effects and potential complications may occur. Preservation of quality of life is a concern in many cancer-related therapies, and the same goal should apply in TACE. This study aimed to determine the effect of TACE on the immediate health-related quality of life (HRQoL) of Filipino patients with unresectable HCC.

A prospective observational survey study of 18 HCC patients who underwent TACE was conducted. HRQoL scores were measured using the validated EORTC QLQ-C30 and QLQ-HCC18 questionnaires, 1-2 days before and two weeks after TACE. Baseline clinical data, which included tumor characteristics, Child-Pugh score, and performance status score, were also obtained. Changes in HRQoL scores before and after TACE, and any association of demographic and clinical variables with HRQoL outcomes were assessed.

Patients experienced overall decline in their global health status and functional scores with increase in their symptom scores after undergoing TACE. Statistically significant deterioration was observed in global health status (-13.9%), physical functioning (-23.0%), and role functioning (-31.4%). Alcohol users had lower global health status scores at baseline and follow-up, although there was no significant difference in the degree of decline in their post-TACE scores compared with non-alcohol users. Patients with BCLC stage C disease also had lower global health status scores at baseline, although scores were no longer significantly different from patients of other stages on post-TACE follow-up. Patients with BCLC stage B tumor experienced significant decline in their global health status scores. The presence of minimal ascites at baseline was associated with less deterioration in physical function scores after TACE. Largest and significant increases in symptomatology were seen for appetite loss (+41.1%), fever (+30.3%), fatigue (+28.5%), and general pain (+25.1%).

TACE can negatively affect the HRQoL of Filipino patients in the early phase after treatment, with significant deteriorations in global health status, physical, and role functioning, and increased severity in symptoms, especially appetite loss, fever, fatigue and pain. Knowledge of these changes should be used to improve patient care, compliance, and expectations.

Hepatocellular carcinoma (HCC) is well characterized as a heterogeneous disease. Its late-stage diagnosis and chemotherapy resistance make it one of the refractory tumors in China. Natural killer (NK) cells play a significant role in immune surveillance. However, NK cells become dysfunctional in the progression of HCC, leading to tumor immune escape. This article reviews the recent progress on different strategies of NK cell-based immunotherapy in treating HCC, including direct adoptive NK cell transfer, gene engineering in NK cell, NK cell receptor targeting, immunosuppressive microenvironment modification, and tumor toxicity enhancement by cytokines or traditional Chinese medicine. These NK cell-based strategies have shown promising therapeutic potential.

OBJECTIVE: To assess the risk of aristolochic acid (AA)-associated cancer in patients with AA nephropathy (AAN). METHODS: A retrospective study was conducted on patients diagnosed with AAN at Peking University First Hospital from January 1997 to December 2014. Long-term surveillance and follow-up data were analyzed to investigate the influence of different factors on the prevalence of cancer. The primary endpoint was the incidence of liver cancer, and the secondary endpoint was the incidence of urinary cancer during 1 year after taking AA-containing medication to 2014. RESULTS: A total of 337 patients diagnosed with AAN were included in this study. From the initiation of taking AA to the termination of follow-up, 39 patients were diagnosed with cancer. No cases of liver cancer were observed throughout the entire follow-up period, with urinary cancer being the predominant type (34/39, 87.17%). Logistic regression analysis showed that age, follow-up period, and diabetes were potential risk factors, however, the dosage of the drug was not significantly associated with urinary cancer. CONCLUSIONS No cases of liver cancer were observed at the end of follow-up. However, a high prevalence of urinary cancer was observed in AAN patients. Establishing a direct causality between AA and HCC is challenging.

Hepatocellular carcinoma (HCC) is one of the most common malignancies and is a major cause of cancer-related mortalities worldwide (Forner et al., 2018; He et al., 2023). Sarcopenia is a syndrome characterized by an accelerated loss of skeletal muscle (SM) mass that may be age-related or the result of malnutrition in cancer patients (Cruz-Jentoft and Sayer, 2019). Preoperative sarcopenia in HCC patients treated with hepatectomy or liver transplantation is an independent risk factor for poor survival (Voron et al., 2015; van Vugt et al., 2016). Previous studies have used various criteria to define sarcopenia, including muscle area and density. However, the lack of standardized diagnostic methods for sarcopenia limits their clinical use. In 2018, the European Working Group on Sarcopenia in Older People (EWGSOP) renewed a consensus on the definition of sarcopenia: low muscle strength, loss of muscle quantity, and poor physical performance (Cruz-Jentoft et al., 2019). Radiological imaging-based measurement of muscle quantity or mass is most commonly used to evaluate the degree of sarcopenia. The gold standard is to measure the SM and/or psoas muscle (PM) area using abdominal computed tomography (CT) at the third lumbar vertebra (L3), as it is linearly correlated to whole-body SM mass (van Vugt et al., 2016). According to a "North American Expert Opinion Statement on Sarcopenia," SM index (SMI) is the preferred measure of sarcopenia (Carey et al., 2019). The variability between morphometric muscle indexes revealed that they have different clinical relevance and are generally not applicable to broader populations (Esser et al., 2019).

INTRODUCTION: Ultrasonography (US) is the current standard of care for imaging surveillance in patients at risk of hepatocellular carcinoma (HCC). Magnetic resonance imaging (MRI) has been explored as an alternative, given the higher sensitivity of MRI, although this comes at a higher cost. We performed a cost-effective analysis comparing US and dual-sequence non-contrast-enhanced MRI (NCEMRI) for HCC surveillance in the local setting. METHODS: Cost-effectiveness analysis of no surveillance, US surveillance and NCEMRI surveillance was performed using Markov modelling and microsimulation. At-risk patient cohort was simulated and followed up for 40 years to estimate the patients' disease status, direct medical costs and effectiveness. Quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio were calculated. RESULTS: Exactly 482,000 patients with an average age of 40 years were simulated and followed up for 40 years. The average total costs and QALYs for the three scenarios - no surveillance, US surveillance and NCEMRI surveillance - were SGD 1,193/7.460 QALYs, SGD 8,099/11.195 QALYs and SGD 9,720/11.366 QALYs, respectively. CONCLUSION Despite NCEMRI having a superior diagnostic accuracy, it is a less cost-effective strategy than US for HCC surveillance in the general at-risk population. Future local cost-effectiveness analyses should include stratifying surveillance methods with a variety of imaging techniques (US, NCEMRI, contrast-enhanced MRI) based on patients' risk profiles.

RATIONALE/OBJECTIVE

Hepatic Resection (HR) has emerged as a potentially curative treatment for HCC, particularly in Barcelona Clinic Liver Cancer – B (BCLC-B) patients, even though Transarterial Chemoembolization (TACE) is the standard of care according to the BCLC staging system. This study aimed to investigate the characteristics, survival rates and outcomes of patients who underwent HR for HCC BCLC-B at a single center over a 10-year period.

Patients who were diagnosed HCC BCLC-B and had undergone HR from January 2011 to December 2021 were analyzed. Only complete records with long-term follow-up were included in the study. The authors described patient characteristics, calculated overall survival rates, and assessed associations between patient, disease factors, and survival.

Of 344 patients who underwent HR, 20 of them had complete records with long-term follow-up. This cohort had a median age of 57, predominantly male (70%), exhibiting a median alpha-fetoprotein (AFP) level of 230.5 ng/mL and an average of 4 nodules. Lymphovascular invasion was evident in 65%, with 85% displaying negative primary tumor margins. Major hepatectomy was the primary procedure (50%), followed by bisegmentectomy (40%) and trisegmentectomy (10%). The 1, 2 and 3-year survival rates post-hepatic resection (HR) for HCC BCLC-B stood at 65%, 35% and 25% respectively.

The study shows that the institution’s treatment approach for BCLC-B HCC patients achieved acceptable 3-year survival rates, and the median overall survival rate observed are comparable with global data. This study highlights hepatic resection as a potential curative option for BCLC-B HCC patients.

Knowledge of these changes should be used to improve patient care, compliance, and expectations.

BACKGROUND: Glutamine synthetase (GS) and arginase 1 (Arg1) are widely used pathological markers that discriminate hepatocellular carcinoma (HCC) from intrahepatic cholangiocarcinoma; however, their clinical significance in HCC remains unclear. METHODS: We retrospectively analyzed 431 HCC patients: 251 received hepatectomy alone, and the other 180 received sorafenib as adjuvant treatment after hepatectomy. Expression of GS and Arg1 in tumor specimens was evaluated using immunostaining. mRNA sequencing and immunostaining to detect progenitor markers (cytokeratin 19 [CK19] and epithelial cell adhesion molecule [EpCAM]) and mutant TP53 were also conducted. RESULTS: Up to 72.4% (312/431) of HCC tumors were GS positive (GS+). Of the patients receiving hepatectomy alone, GS negative (GS-) patients had significantly better overall survival (OS) and recurrence-free survival (RFS) than GS+ patients; negative expression of Arg1, which is exclusively expressed in GS- hepatocytes in the healthy liver, had a negative effect on prognosis. Of the patients with a high risk of recurrence who received additional sorafenib treatment, GS- patients tended to have better RFS than GS+ patients, regardless of the expression status of Arg1. GS+ HCC tumors exhibit many features of the established proliferation molecular stratification subtype, including poor differentiation, high alpha-fetoprotein levels, increased progenitor tumor cells, TP53 mutation, and upregulation of multiple tumor-related signaling pathways. CONCLUSIONS GS- HCC patients have a better prognosis and are more likely to benefit from sorafenib treatment after hepatectomy. Immunostaining of GS may provide a simple and applicable approach for HCC molecular stratification to predict prognosis and guide targeted therapy.
