Abstract
OBJECTIVES Criteria for antiviral treatment initiation in Thailand were complex and difficult to implement. This study determined the cost-effectiveness of 2 simplified antiviral treatment initiation criteria among patients with chronic hepatitis B in Thailand. METHODS A hybrid model of the decision tree and Markov model was developed. Two simplified antiviral treatment initiation criteria were the expanded criteria, treating patients with hepatitis B surface antigen positive and viral load (hepatitis B virus deoxyribonucleic acid) >2000 IU/mL or cirrhosis by tenofovir alafenamide (TAF), and the test-and-treat criteria, treating patients with hepatitis B surface antigen positive and viral load >10 IU/mL or cirrhosis by TAF. PubMed was searched from its inception to July 2023 to identify input parameters. Best supportive care was chosen for patients who were ineligible for TAF. Incremental cost-effectiveness ratio per quality-adjusted life-year (QALY) was calculated. RESULTS The expanded criteria and the test-and-treat could reduce the occurrence of patients progressing to hepatocellular carcinoma. In particular, both criteria could reduce 4846 new cases of hepatocellular carcinoma per 100 000 patients. The incremental cost-effectiveness ratios for the expanded criteria and the test-and-treat criteria were 24 838 Thai baht (THB)/QALY and 163 060 THB/QALY, respectively. CONCLUSIONS At the current willingness to pay of 160 000 THB/QALY, the expanded criteria were cost-effective, but the test-and-treat criteria were not cost-effective to be the simplified antiviral treatment initiation criteria for patients with chronic hepatitis B in Thailand.

Abstract
OBJECTIVE Several risk prediction algorithms have been developed to guide antiviral therapy initiation among patients with chronic hepatitis B (CHB). This study assessed the cost-effectiveness and budget impact of three risk prediction algorithms among patients with CHB in Thailand. METHODS A decision tree with a Markov model was constructed. Three risk prediction algorithms were compared with current practices including HePAA, TREAT-B and REACH-B. PubMed was searched from its inception to December 2022 to identify inputs. Tenofovir alafenamide and best supportive care were selected for antiviral-eligible patients, and incremental cost-effectiveness ratios per quality-adjusted life year (QALY) were calculated. RESULTS Our base case analysis showed that HePAA and REACH-B could provide better QALY (0.098 for HePAA and 0.921 for REACH-B) with decreased total healthcare costs (-10909 THB for HePAA and -8,637 THB for REACH-B). TREAT-B provided worse QALY (-0.144) with increased total healthcare costs (10,435 THB). The budget impacts for HePAA and REACH-B were 387 million THB and 3,653 million THB, respectively. CONCLUSION HePAA and REACH-B algorithms are cost-effective in guiding antiviral therapy initiation. REACH-B is the most cost-effective option, but has a high budget impact. Policymakers should consider both cost-effectiveness and budget impact findings when deciding which algorithm should be implemented.

Abstract
Hepatocellular carcinoma (HCC) surveillance rates are suboptimal. We aimed to identify HCC surveillance barriers from both physician's and patient's perspectives and assess the effectiveness of physician education using social networks. A nationwide survey with 513 physicians and another single-center survey with 315 HCC-risk patients were conducted. Barriers to suboptimal surveillance were identified using univariate and multivariate logistic regression analysis. We educated 143 physicians by sending brief notes on HCC surveillance guidelines via social networks and re-evaluated their knowledge after 60 days using t test. Surveys showed 458 (86.3%), 254 (47.8%), and 225 (42.4%) physicians recommended surveillance in patients with cirrhosis, at-risk hepatitis B virus, and hepatitis C virus infection, respectively. Only 228 (42.9%) and 241 (38.0%) respondents adhered to recommended surveillance tools and interval, respectively. The main surveillance barriers among physicians were the lack of knowledge and resource limitations. The lack of a doctor's prescription was identified as a major barrier by patient' perspectives (odds ratio 1.4, 95% CI: 1.1-1.8, P = .024). Education via social networks enhanced physicians' knowledge, with pre- and post-education scores for guideline awareness of 63.0% versus 84.3% (P < .001) and for surveillance indication and tools of 40.0% versus 63.0% (P = .001), and 42.0% versus 59.3% (P = .015), respectively. Physicians' knowledge gap is a primary barrier for adherence to HCC surveillance protocols. Brief education via social networks shows effectiveness at increasing physicians' knowledge of HCC surveillance.

Vaccines (Basel) 2022; 10:vaccines10060950. [PMID: 35746558 PMCID: PMC9227762 DOI: 10.3390/vaccines10060950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 05/13/2022] [Accepted: 06/11/2022] [Indexed: 12/10/2022] Open
Abstract
Background: Understanding the public health value of a vaccine at an early stage of development helps in valuing and prioritizing the investment needed. Here we present the potential cost-effectiveness of an upcoming 12 valent pneumococcal conjugate vaccine (PCV 12) in the case study country, Thailand. Methods: The cost-effectiveness analysis included a hypothetical scenario of three doses (2 + 1 regimen) PCV12 introduction in the national immunization program of Thailand compared to no PCV, PCV10, and PCV13 among <6 months old from a societal perspective with a lifetime horizon and one-year cycle length. Data from Thailand, as well as assumptions supported by the literature, were used in the analysis. The price of PCV12 was assumed similar to that of PCV10 or PCV13 for GAVI’s eligible countries based on inputs from stakeholder meeting. A one-way sensitivity analysis was conducted using 0.5−1.5 times the base price of PCV12. Results were presented in incremental cost-effectiveness ratio (ICER) in terms of monetary value per quality-adjusted life-year (QALY) gained. Results: Vaccination with PCV12 among a hypothetical cohort of 100,000 Thai children is expected to avert a total of 5358 cases which includes 5 pneumococcal meningitis, 43 pneumococcal bacteremia, 5144 all-cause pneumonia, and 166 all-cause acute otitis media compared to no vaccination. The national PCV12 vaccination program is a cost-saving strategy compared to the other three strategies. The one-way sensitivity analysis showed PCV12 is a cost-saving strategy when 1.5 times the base price of PCV12 was assumed. Conclusions: Within the limitations of hypothetical assumptions and price points incorporated, the study indicates the potential public health value of PCV12 in Thailand.

Abstract
ObjectiveThis study aimed to estimate the public hospital costs associated with primary liver cancer (PLC) in the first and second years following the cancer diagnosis.MethodsThis study linked administrative datasets of patients diagnosed with PLC in Victoria, Australia, from January 2008 to December 2015. The health system perspective was adopted to estimate the direct healthcare costs associated with PLC, based on inpatient and emergency costs. Costs were estimated for the first 12 months and 12-24 months after the PLC diagnosis and expressed in 2017 Australian dollars (A$). The cost estimated was then extrapolated nationally. The linear mixed model with a Box-Cox transformation of the costs was used to explore the relationship between costs and patients' sociodemographic and clinical characteristics.ResultsFor the first 12 months, the total and annual per-patient cost was A$211.4 million and A$63 664, respectively. Costs for the subsequent year were A$49.7 million and A$46 751, respectively. Regarding the cost extrapolation to Australia, the total cost was A$137 million for the first 12 months after notification and A$42.6 million for the period from 12 to 24 months. Higher costs per episode of care were mostly associated with older age, hepatocellular carcinoma type of PLC, metropolitan hospitals, and Asian birth region.ConclusionThis study showed the public hospital admission and emergency costs associated with PLC and the substantial economic burden this cancer has placed on the Australian health system.

Abstract
Chronic hepatitis B (CHB) infection is a significant risk factor for developing hepatocellular carcinoma (HCC). As HCC is associated with significant morbidity and mortality, screening patients with CHB at a high risk for HCC is recommended in an attempt to improve these outcomes. However, the screening recommendations on who to screen and how often are not uniform. Identifying patients at the highest risk of HCC would allow for the best use of health resources. In this review, we evaluate the literature on screening patients with CHB for HCC, strategies for optimizing adherence to screening, and potential risk stratification tools to identify patients with CHB at a high risk of developing HCC.

Abstract
OBJECTIVES Many economic evaluations of hepatocellular carcinoma (HCC) screenings have been conducted; however, these vary substantially with regards to screening strategies, patient group, and setting. This review aims to report the current knowledge of the cost-effectiveness of screening and describe the published data. METHODS We conducted a search of biomedical and health economic databases up to July 2020. We included full and partial health economic studies if they evaluated the costs or outcomes of HCC screening strategies. RESULTS The review included 43 studies. Due to significant heterogeneity in key aspects across the studies, a narrative synthesis was conducted. Most studies reported using ultrasound or alpha fetoprotein as screening strategies. Screening intervals were mostly annual or biannual. Incidence, diagnostic performance, and health state utility values were the most critical parameters affecting the cost-effectiveness of screening. The majority of studies reported HCC screening to be cost-effective, with the biannual ultrasound + alpha fetoprotein standing out as the most cost-effective strategy. However, few studies considered the utilization rate, and none considered the diagnostic performance of ultrasound in the context of central adiposity. Computed tomography and magnetic resonance imaging were also evaluated, but its cost-effectiveness was still controversial. CONCLUSIONS Although many studies suggested HCC screening was cost-effective, substantial limitations of the quality of these studies means the results should be interpreted with caution. Future modeling studies should consider the impact of central adiposity on the precision of ultrasound, real-world utilization rates and projections of increased HCC incidence.

Abstract
Current study aimed to estimate clinical and economic outcomes of providing the Haemophilus influenzae type b (Hib) vaccination as a national vaccine immunization program in Thailand. A decision tree combined with Markov model was developed to simulate relevant costs and health outcomes covering lifetime horizon in societal and health care payer perspectives. This analysis considered children aged under 5 years old whom preventive vaccine of Hib infection are indicated. Two combined Hib vaccination schedules were considered: three-dose series (3 + 0) and three-dose series plus a booster does (3 + 1) compared with no vaccination. Budget impact analysis was also performed under Thai government perspective. The outcomes were reported as Hib-infected cases averted and incremental cost-effectiveness ratios (ICERs) in 2014 Thai baht (THB) ($) per quality-adjusted life year (QALY) gained. In base-case scenario, the model estimates that 3,960 infected cases, 59 disability cases, and 97 deaths can be prevented by national Hib vaccination program. The ICER for 3 + 0 schedule was THB 1,099 ($34) per QALY gained under societal perspective. The model was sensitive to pneumonia incidence among aged under 5 years old and direct non-medical care cost per episode of Hib pneumonia. Hib vaccination is very cost-effective in the Thai context. The budget impact analysis showed that Thai government needed to invest an additional budget of 110 ($3.4) million to implement Hib vaccination program. Policy makers should consider our findings for adopting this vaccine into national immunization program.

Cost-effectiveness of EOB-MRI for Hepatocellular Carcinoma in Japan. Clin Ther 2017; 39:738-750.e4. [PMID: 28363694 DOI: 10.1016/j.clinthera.2017.03.006] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2017] [Revised: 02/28/2017] [Accepted: 03/03/2017] [Indexed: 01/20/2023]
Abstract
PURPOSE The objective of the study was to evaluate the cost-effectiveness of gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) in the diagnosis and treatment of hepatocellular carcinoma (HCC) in Japan compared with extracellular contrast media-enhanced MRI (ECCM-MRI) and contrast media-enhanced computed tomography (CE-CT) scanning. METHODS A 6-stage Markov model was developed to estimate lifetime direct costs and clinical outcomes associated with EOB-MRI. Diagnostic sensitivity and specificity, along with clinical data on HCC survival, recurrence, treatment patterns, costs, and health state utility values, were derived from predominantly Japanese publications. Parameters unavailable from publications were estimated in a Delphi panel of Japanese clinical experts who also confirmed the structure and overall approach of the model. Sensitivity analyses, including one-way, probabilistic, and scenario analyses, were conducted to account for uncertainty in the results. FINDINGS Over a lifetime horizon, EOB-MRI was associated with lower direct costs (¥2,174,869) and generated a greater number of quality-adjusted life years (QALYs) (9.502) than either ECCM-MRI (¥2,365,421, 9.303 QALYs) or CE-CT (¥2,482,608, 9.215 QALYs). EOB-MRI was superior to the other diagnostic strategies considered, and this finding was robust over sensitivity and scenario analyses. A majority of the direct costs associated with HCC in Japan were found to be costs of treatment. The model results revealed the superior cost-effectiveness of the EOB-MRI diagnostic strategy compared with ECCM-MRI and CE-CT. IMPLICATIONS EOB-MRI could be the first-choice imaging modality for medical care of HCC among patients with hepatitis or liver cirrhosis in Japan. Widespread implementation of EOB-MRI could reduce health care expenditures, particularly downstream treatment costs, associated with HCC.

Abstract
AIM To determine the role of screening and surveillance of hepatocellular carcinoma (HCC) in treatment-naïve chronic hepatitis B (CHB) patients.
METHODS We recruited 2293 CHB patients (both males and females; aged 20-65 years). All patients were screened and underwent surveillance using abdominal ultrasonography (AUS) and serum alpha-fetoprotein (AFP) assay every 6 mo. The diagnosis, staging and treatment of HCC followed the American Association for the Study of Liver Diseases practice guidelines and the Barcelona Clinic Liver Cancer guidelines. The exclusion criteria included: decompensated cirrhosis; a history of any cancer in the last 5 years; previous antiviral treatment for CHB; concurrent infection with hepatitis C virus or human immunodeficiency virus; a Karnofsky Performance Status score < 60%; or any medical condition preventing eligibility to complete the protocol. The prevalence and incidence rates of HCC were determined; survival rates were calculated at 3-year post HCC diagnosis. The sensitivity and specificity were calculated on a per-patient basis.
RESULTS Among 2293 treatment-naïve CHB patients, seven cases had HCC at initial screening, giving a prevalence rate of 305 per 100000 persons; 3.3% were diagnosed with liver cirrhosis, all of which were Child-Pugh class A. With a median follow-up time of 42 (range, 3-48) mo, 10 additional cases were diagnosed with HCC, resulting in an incidence rate of 143 per 100000 persons per year. This burden was as high as that reported in other studies from East Asian countries. All HCC patients were aged ≥ 40 years. Most were at an early stage (Stage 0, A or B); 14/17 cases were successfully treated with surgical resection or radiofrequency ablation, with a high 3-year survival rate of 90%. Hemangioma was the most common focal liver lesion in CHB patients detected by AUS; the main causes of AFP elevation at the initial screening were cirrhosis, increased alanine aminotransferase level and HCC. AUS detected 16/17 HCC cases whereas AFP levels ≥ 20 μg/L at diagnosis were observed in only 7/17 patients, most with a tumor size > 5 cm. For HCC screening and surveillance, AUS had a sensitivity and specificity of 94% and 82%, respectively, whereas the sensitivity and specificity of AFP at a cut-off value of ≥ 20 μg/L were 41% and 98%, respectively. Combined use of AUS and AFP assay did not improve effectiveness.
CONCLUSION Implementation of active screening and surveillance using AUS to detect early-stage HCC in naïve CHB patients aged ≥ 40 years in an endemic area is of benefit.

Abstract
OBJECTIVE To investigate whether the expression of serum soluble neural cell adhesion molecule (sNCAM) is associated with hepatic encephalopathy (HE) in hepatocelular carcinoma (HCC) patients. MATERIALS AND METHODS The Oncomine Cancer Microarray database was used to determine the clinical relevance of NCAM expression in different kinds of human cancers. Sera from 75 HCC cases enrolled in this study were assessed for expression of sNCAM by enzyme linked immunosorbent assay (ELISA). RESULTS Dependent on the Oncomine Cancer Microarray database analysis, NCAM was down regulated in 10 different kinds of cancer, like bladder cancer, brain and central nervous system cancer, while up-regulated in lung cancer, uterine corpus leiomyoma and sarcoma, compared to normal groups. Puzzlingly, NCAM expression demonstrated no significant difference between normal and HCC groups. However, we found by quantitative ELISA that the level of sNCAM in sera from HCC patients with HE (347.4±151.9 ng/ml) was significantly more up-regulated than that in HCC patients without HE (260.3±104.2 ng/ml), the p-value being 0.008. sNCAM may be an important risk factor of HE in HCC patients, the correlation coefficients was 0.278 (P< 0.05) on rank correlation analysis. CONCLUSIONS This study highlights that up-regulated level of serum sNCAM is associated with HE in HCC patients and suggests that the high expression can be used as an indicator.

CYP2C19 Genotype Could be a Predictive Factor for Aggressive Manifestations of Hepatocellular Carcinoma Related with Chronic Hepatitis B Infection in Thailand. Asian Pac J Cancer Prev 2016; 16:3253-6.

Abstract
BACKGROUND Chronic hepatitis B virus (HBV) infection related hepatocellular carcinoma (HCC) is a major health problem in the Asia-Pacific region including Thailand. Several factors have been proposed as contributing to hepatocarcinogenesis. This study was aimed to investigate the impact of CYP2C19 genotypic polymorphism in HCC related to chronic HBV infection in Thailand. MATERIALS AND METHODS A cross-sectional study was performed between April 2014 and January 2015. Chronic HBV patients with HCC (n=50) and without HCC (n=50) were included. Clinical information and blood samples of all patients were collected. The CYP2C19 genotype was determined by polymerase chain reaction-restriction fragment length polymorphism method, and was classified as rapid metabolizer (RM), intermediate metabolizer (IM) or poor metabolizer (PM). RESULTS The CYP2C19 genotype frequencies of RM, IM and PM in HBV patients were found to be 19/50 (38%), 25/50 (50%) and 6/50 (12%), respectively. The CYP2C19 genotype frequencies of RM, IM and PM in HBV with HCC patients were 21/50 (42%), 25/50 (50%) and 4/50 (8%), respectively. The distribution of CYP2C19 genotype was not different between patients with and without HCC. Interestingly, among HBV with HCC patients, the RM genotype of CYP2C19 tended to increase risk of aggressive manifestation (OR=2.89, 95%CI=0.76-11.25, P-value = 0.07), compared with non RM genotype carriers. CONCLUSIONS CYP2C19 genotype IM was the most common genotype in Thai patients with chronic HBV infection. In addition, genotype RM could be an associated factor for aggressive presentation in HCC related to chronic HBV infection.

Abstract
BACKGROUND Serum Golgi protein 73 (GP73) as a novel and potential marker for diagnosing hepatocellular carcinoma (HCC) have been found to be elevated in HCC patients and associated with clinical variables representing tumor growth and invasiveness. The aim of this study was to prepare a pair of monoclonal antibodys (mAbs) against GP73 and develop a newly designed double-antibody sandwich enzyme-linked immunosorbent assay (s-ELISA), which would be used in the detection of serum GP73 (sGP73) as well as in the diagnosis of HCC. MATERIALS AND METHODS Produced by prokaryotic expression, the purified recombinant GP73 (rGP73), produced by prokaryotic expression, was used to immunize the Balb/c mice. Two hybridoma cell lines against GP73 were obtained by fusing mouse Sp2/0 myeloma cells with spleen cells from the immunized mice. The titers of anti-GP73 mAb reached 1:243,000. Western blotting analysis and Immunohistochemistry staining revealed that anti-GP73 mAb could recognize GP73 protein. The double-antibody s-ELISA was successfully established and validated by 119 HCC and 103 normal serum samples. RESULTS showed that the detection limit of this method could reach 1.56 ng/ml, and sGP73 levels in HCC group (mean=190.6 ng/ml) were much higher than those of in healthy controls (mean=70.92 ng/ml). CONCLUSIONS Results of our study not only showed that sGP73 levels of HCC patients were significantly higher than those of healthy controls, but also indicated that the laboratory homemade anti-GP73 mAbs could be the optimal tool used in evaluating sGP73 levels, which would provide a solid foundation for subsequent clinical applications.
