Abstract
BACKGROUND & AIMS Guidelines suggest endoscopic screening for esophageal adenocarcinoma (EAC) among individuals with symptoms of gastroesophageal reflux disease (GERD) and additional risk factors. We aimed to determine at what age to perform screening and whether sex and race should influence the decision. METHODS We conducted comparative cost-effectiveness analyses using 3 independent simulation models. For each combination of sex and race (White/Black, 100,000 individuals each), we considered 41 screening strategies, including one-time or repeated screening. The optimal strategy was that with the highest effectiveness and an incremental cost-effectiveness ratio <$100,000 per quality-adjusted life-year gained. RESULTS Among White men, 536 EAC deaths were projected without screening, and screening individuals with GERD twice at ages 45 and 60 years was optimal. Screening the entire White male population once at age 55 years was optimal in 26% of probabilistic sensitivity analysis runs. Black men had fewer EAC deaths without screening (n = 84), and screening those with GERD once at age 55 years was optimal. Although White women had slightly more EAC deaths (n = 103) than Black men, the optimal strategy was no screening, although screening those with GERD once at age 55 years was optimal in 29% of probabilistic sensitivity analysis runs. Black women had a very low burden of EAC deaths (n = 29), and no screening was optimal, as benefits were very small and some strategies caused net harm. CONCLUSIONS The optimal strategy for screening differs by race and sex. White men with GERD symptoms can potentially be screened more intensely than is recommended currently. Screening women is not cost-effective and may cause net harm for Black women.

Abstract
Ideally, patient-centered trial information material encourages the discussion with the treating physician, and helps patients making trade-offs regarding treatment decisions In a situation of possible equivalent treatment options in terms of overall survival (OS), it can make it easier to weigh up advantages and disadvantages. Preferences for choice of treatment in esophageal cancer (EC) are complex, and no standardized assessment tools are available. We will explore patient’s factors for treatment choice and develop a comprehensive patient information leaflet for the inclusion into randomized controlled trials (RCT) on EC. We conduct a cross-sectional, observational study based on a mixed-methods design with patients suffering from non-metastatic EC with post-neoadjuvant complete response after neoadjuvant chemotherapy (nCT) or neoadjuvant chemoradiation (nCRT), to develop patient-centered trial information material. This pilot study is performed in a concept development phase and a subsequent pilot phase. We start with patient interviews (n = 10–15) in the concept development phase to evaluate patients’ needs, and develop a Preference and Decision Aid Questionnaire (PDAQ). We pre-test the PDAQ with another n = 10 patients with EC after nCT or nCRT, former patients from a self-help organization, and n = 10 medical experts for their comments on the questionnaire. In the pilot phase, a multicenter trial using the PDAQ and additional measures is carried out (n = 120). Based on evidence of a possible equivalence in terms of OS of the treatment options “surgery as needed” and “surgery on principle” in patients with post-neoadjuvant complete response of EC, this pilot study on patient participation is conducted to assess patient’s needs and preferences, and optimize patients’ inclusion in a planned RCT. The aim is to develop patient-centered trial information material for the RCT to increase patients’ consent and compliance with the randomized treatment. The trial is registered at the German Clinical Trials Register (DRKS00022050, October 15, 2020).

The Optimal Age to Stop Endoscopic Surveillance of Patients With Barrett's Esophagus Based on Sex and Comorbidity: A Comparative Cost-Effectiveness Analysis. Gastroenterology 2021; 161:487-494.e4. [PMID: 33974935 PMCID: PMC8495224 DOI: 10.1053/j.gastro.2021.05.003] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Revised: 04/15/2021] [Accepted: 05/01/2021] [Indexed: 12/26/2022]
Abstract
BACKGROUND AND AIMS Current guidelines recommend surveillance for patients with nondysplastic Barrett's esophagus (NDBE) but do not include a recommended age for discontinuing surveillance. This study aimed to determine the optimal age for last surveillance of NDBE patients stratified by sex and level of comorbidity. METHODS We used 3 independently developed models to simulate patients diagnosed with NDBE, varying in age, sex, and comorbidity level (no, mild, moderate, and severe). All patients had received regular surveillance until their current age. We calculated incremental costs and quality-adjusted life-years (QALYs) gained from 1 additional endoscopic surveillance at the current age versus not performing surveillance at that age. We determined the optimal age to end surveillance as the age at which incremental cost-effectiveness ratio of 1 more surveillance was just less than the willingness-to-pay threshold of $100,000/QALY. RESULTS The benefit of having 1 more surveillance endoscopy strongly depended on age, sex, and comorbidity. For men with NDBE and severe comorbidity, 1 additional surveillance at age 80 years provided 4 more QALYs per 1000 patients with BE at an additional cost of $1.2 million, whereas for women with severe comorbidity the benefit at that age was 7 QALYs at a cost of $1.3 million. For men with no, mild, moderate, and severe comorbidity, the optimal ages of last surveillance were 81, 80, 77, and 73 years, respectively. For women, these ages were younger: 75, 73, 73, and 69 years, respectively. CONCLUSIONS Our comparative modeling analysis illustrates the importance of considering comorbidity status and sex when deciding on the age to discontinue surveillance in patients with NDBE.

Abstract
BACKGROUND Upper tract urothelial carcinoma (UTUC) is clinically understudied, and there are no definitive recommendations regarding timing of perioperative chemotherapy. The objective of this study was to compare 3 treatment pathways in UTUC: nephroureterectomy (NU) alone, neoadjuvant chemotherapy (NAC), and adjuvant chemotherapy (AC) using a microsimulation model. PATIENTS AND METHODS An individual-level state transition model was constructed using TreeAgePro software to compare treatment strategies for patients with newly diagnosed UTUC. The base case was that of a 70-year-old patient with a radiographically localized upper tract tumor. Primary outcome was quality-adjusted life expectancy. Secondary outcomes included crude overall survival, rates of adverse events, and bladder cancer diagnoses. RESULTS A total of 100,000 patients were simulated. NAC was preferred, with an estimated quality-adjusted life expectancy of 7.50 years versus 6.79 years with NU alone and 7.23 years with AC. Median crude overall survival was 123 months with NAC, 96 months with NU only, and 111 months with AC. Overall, 40.0% of patients in the AC group with invasive pathology completed chemotherapy. In the NAC group, 83.3% of patients completed chemotherapy. In the NAC group, 37.5% of patients experienced an adverse chemotherapy event compared to 15.1% of patients in the AC group. Bladder cancer recurrence rates were 64.9%, 65.9%, and 67.4% over the patient's lifetime for the NU, NAC, and AC strategies, respectively. CONCLUSION This study supports the increased use of NAC in UTUC until robust randomized trials are completed. The ultimate choice should be based on patient and tumor factors.

Abstract
INTRODUCTION Clinical guidelines recommend surveillance of patients with Barrett's esophagus (BE). However, the surveillance intervals in practice are shorter than policy recommendations. We aimed to determine how this policy-practice gap affects the costs and benefits of BE surveillance. METHODS We used the Netherlands as an exemplary Western country and simulated a cohort of 60-year-old patients with BE using the Microsimulation Screening Analysis model-esophageal adenocarcinoma (EAC) microsimulation model. We evaluated surveillance according to the Dutch guideline and more intensive surveillance of patients without dysplastic BE and low-grade dysplasia. For each strategy, we computed the quality-adjusted life years (QALYs) gained and costs compared with no surveillance. We also performed a budget impact analysis to estimate the increased costs of BE management in the Netherlands for 2017. RESULTS Compared with no surveillance, the Dutch guideline incurred an additional &OV0556;5.0 ($5.7) million per 1,000 patients with BE for surveillance and treatment, whereas 57 esophageal adenocarcinoma (EAC) cases (>T1a) were prevented. With intensive and very intensive surveillance strategies for both nondysplastic BE and low-grade dysplasia, the net costs increased by another &OV0556;2.5-5.6 ($2.8-6.5) million while preventing 10-19 more EAC cases and gaining 33-60 more QALYs. On a population level, this amounted to &OV0556;21-47 ($24-54) million (+32%-70%) higher healthcare costs in 2017. DISCUSSION The policy-practice gap in BE surveillance intervals results in 50%-114% higher net costs for BE management for only 10%-18% increase in QALYs gained, depending on actual intensity of surveillance. Incentives to eliminate this policy-practice gap should be developed to reduce the burden of BE management on patients and healthcare resources.

Abstract
Purpose This study evaluates the cost-effectiveness of a quantitative multi-biomarker assay (the Assay) that stratifies patients with Barrett’s Esophagus (BE) by risk of progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) and can be used to guide clinical decisions, versus the current guidelines (standard of care [SOC]) for surveillance and treatment of BE. Patients and methods Markov decision modeling and simulation were used to compare cost and quality-adjusted life-years (QALYs) from the perspective of a US health insurer with care delivered by an integrated health system. Model assumptions and disease progression probabilities were derived from the literature. Performance metrics for the Assay were from an independent clinical validation study. Cost of the Assay was based on reimbursement rates from multiple payers. Other costs were derived from Geisinger payment data. Results Base-case model results for a 5-year period comparing the Assay-directed care to the SOC estimated an incremental cost-effectiveness ratio (ICER) of $52,483/QALY in 2012 US dollars. Assay-directed care increased the use of endoscopic treatments by 58.4%, which reduced the progression to HGD, EAC and reduced EAC-related deaths by 51.7%, 47.1%, and 37.6%, respectively, over the 5-year period. Sensitivity analysis indicated that the probability of the Assay being cost-effective compared to the SOC was 57.3% at the $100,000/QALY acceptability threshold. Conclusion Given the model assumptions, the new Assay would be cost-effective after 5 years and improves patient outcomes due to improvement in the effectiveness of surveillance and treatment protocols resulting in fewer patients progressing to HGD and EAC and fewer EAC-related deaths.

Abstract
BACKGROUND Emerging preclinical evidence indicates statins, medications commonly used in the prevention of cardiovascular disease (CVD), inhibit proliferation, promote apoptosis and limit invasiveness of esophageal adenocarcinoma (EAC). Population-based observational data demonstrate statin treatment after diagnosis of EAC is associated with significant reductions in all-cause and cancer-specific mortality. A feasibility study of adjuvant statin therapy following potentially curative resection for EAC has been completed, with planned progression to a full phase III, randomized controlled trial. OBJECTIVE The aim was to estimate the cost-utility of statin therapy following surgical resection for EAC from a UK National Health Service (NHS) perspective. METHODS A Markov model was developed to estimate the costs and outcomes [quality-adjusted life years (QALYs)] for hypothetical cohorts of patients with EAC exposed or not exposed to statins following potentially curative surgical resection. Model parameters were based on estimates from published observational and trial data. Costs, utilities and transition probabilities were modeled to reflect clinical practice from a payer's perspective. Probabilistic and one-way sensitivity analyses were performed to account for uncertainty in key parameters. RESULTS Overall, a cost saving of £6781 per patient was realized with statin treatment compared to no statins. In probabilistic sensitivity analysis, 99% of all iterations were cost saving and 99% of all iterations were less than £20,000 per QALY gained. These results were robust to changes in the price and effectiveness of statins. CONCLUSIONS The cohort exposed to statins had lower costs and better QALY outcomes than the no statin cohort. Assuming a causal improvement in disease outcomes following resection for EAC, statin therapy is very likely to be a cost-saving treatment.

Abstract
OBJECTIVE The purpose of this study is to determine the comparative effectiveness of esophagectomy versus endoscopic mucosal resection followed by radiofrequency ablation (EMR-RFA) for the treatment of Barrett esophagus with high-grade dysplasia (HGD). BACKGROUND HGD of the esophagus may be managed by surgical resection or EMR-RFA. National guidelines suggest that EMR-RFA is effective at eradicating HGD. The comparative effectiveness and cost-effectiveness of EMR-RFA versus esophagectomy for HGD remains unclear. METHODS A decision-analysis model was constructed to represent 3 management strategies for HGD: (1) esophagectomy, (2) EMR-RFA, and (3) endoscopic surveillance. Estimates for model variables were obtained from literature review, and costs were estimated from Medicare fee schedules. Costs and utilities were discounted at an annual rate of 3%. The baseline model was adjusted for alternative age groups and high-risk dysplastic variants. One-way and multivariable probabilistic sensitivity analyses were conducted. RESULTS For a 65-year-old patient, compared to esophagectomy, EMR-RFA yields equivalent utility (11.5 vs 11.4 discounted quality-adjusted life years) with lower total cost ($52.5K vs $74.3K) over the first 20 years. Dominance of EMR-RFA over esophagectomy persists for all age groups. Patients with diffuse or ulcerated HGD are more effectively treated with esophagectomy. Model outcomes are sensitive to estimated rates of disease progression and postintervention utility parameters. CONCLUSIONS Existing evidence supports EMR-RFA over esophagectomy for the treatment of esophageal HGD. Long-term outcomes and more definitive quality-of-life studies for both interventions are crucial to better inform decision-making.

Abstract
BACKGROUND The surveillance of patients with nondysplastic Barrett's esophagus (NDBE) has a high cost and is of limited effectiveness in preventing esophageal adenocarcinoma (EAC). Ablation for NDBE remains expensive and controversial. Biomarkers of genomic instability have shown promise in identifying patients with NDBE at high risk for progression to EAC. Here, we evaluate the cost-effectiveness of using such biomarkers to stratify patients with NDBE by risk for EAC and, subsequently, the cost-effectiveness of ablative therapy. METHODS A Markov decision tree was used to evaluate four strategies in a hypothetical cohort of 50-year old patients with NDBE over their lifetime: strategy I, natural history without surveillance; strategy II, surveillance per current guidelines; strategy III, ablation for all patients; strategy IV, risk stratification with use of a biomarker panel to assess genomic instability (i. e., mutational load [ML]). Patients with no ML underwent minimal surveillance, patients with low ML underwent standard surveillance, and patients with high ML underwent ablation. The incremental cost-effectiveness ratio (ICER) and incremental net health benefit (INHB) were assessed. RESULTS Strategy IV provided the best values for quality-adjusted life years (QALYs), ICER, and INHB in comparison with strategies II and III. RESULTS were robust in sensitivity analysis. In a Monte Carlo analysis, the relative risk for the development of cancer in the patients managed with strategy IV was decreased. Critical determinants of strategy IV cost-effectiveness were the complete response rate, cost of ablation, and surveillance interval in patients with no ML. CONCLUSION The use of ML to stratify patients with NDBE by risk was the most cost-effective strategy for preventive EAC treatment. Targeting ablation toward patients with high ML presents an opportunity for a paradigm shift in the management of NDBE.

Abstract
BACKGROUND As esophagectomy is associated with a considerable complication rate, the aim of this study was to assess the impact of postoperative complications and neoadjuvant treatment on long-term outcome of adenocarcinoma (EAC) and squamous cell carcinoma (SCC) patients. METHODS Altogether, 134 patients undergoing transthoracic esophagectomy between 2005 and 2010 with intrathoracic stapler anastomosis were included in the study. Postoperative complications were allocated into three main categories: overall complications, acute anastomotic insufficiency, and pulmonary complications. Data were collected prospectively and reviewed retrospectively for the purpose of this study. RESULTS SCC patients suffered significantly more often from overall and pulmonary complications (SCC vs. EAC: overall complications 67 vs. 45 %, p = 0.044; pulmonary complications 56 vs. 34 %, p = 0.049). The anastomotic insufficiency rates did not differ significantly (SCC 11%, EAC 15%, p = 0.69). Long-term survival of EAC and SCC patients was not affected by perioperative (overall/pulmonary) complications or by the occurrence of anastomotic insufficiency. Also, neoadjuvant treatment did not influence the incidence of complications or long-term survival. CONCLUSIONS This is the first time the patient population of a center experienced with esophageal cancer surgery was assessed for the occurrence of general and esophageal cancer surgery-specific perioperative complications. Our results indicated that these complications did not affect long-term survival of EAC and SCC patients. Our data support the hypothesis that neoadjuvant treatment might not affect the incidence of perioperative complications or long-term survival after treatment of these tumor subtypes.

High-resolution microendoscopy for esophageal cancer screening in China: A cost-effectiveness analysis. World J Gastroenterol 2015; 21:5513-23. [PMID: 25987774 PMCID: PMC4427673 DOI: 10.3748/wjg.v21.i18.5513] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2014] [Revised: 09/03/2014] [Accepted: 11/08/2014] [Indexed: 02/06/2023] Open
Abstract
AIM To study the cost-effectiveness of high-resolution microendoscopy (HRME) in an esophageal squamous cell carcinoma (ESCC) screening program in China. METHODS A decision analytic Markov model of ESCC was developed. Separate model analyses were conducted for cohorts consisting of an average-risk population or a high-risk population in China. Hypothetical 50-year-old individuals were followed until age 80 or death. We compared three different strategies for both cohorts: (1) no screening; (2) standard endoscopic screening with Lugol's iodine staining; and (3) endoscopic screening with Lugol's iodine staining and an HRME. Model parameters were estimated from the literature as well as from GLOBOCAN, the Cancer Incidence and Mortality Worldwide cancer database. Health states in the model included non-neoplasia, mild dysplasia, moderate dysplasia, high-grade dysplasia, intramucosal carcinoma, operable cancer, inoperable cancer, and death. Separate ESCC incidence transition rates were generated for the average-risk and high-risk populations. Costs in Chinese currency were converted to international dollars (I$) and were adjusted to 2012 dollars using the Consumer Price Index. RESULTS The main outcome measurements for this study were quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER). For the average-risk population, the HRME screening strategy produced 0.043 more QALYs than the no screening strategy at an additional cost of I$646, resulting in an ICER of I$11808 per QALY gained. Standard endoscopic screening was weakly dominated. Among the high-risk population, when the HRME screening strategy was compared with the standard screening strategy, the ICER was I$8173 per QALY. For both the high-risk and average-risk screening populations, the HRME screening strategy appeared to be the most cost-effective strategy, producing ICERs below the willingness-to-pay threshold, I$23500 per QALY. One-way sensitivity analysis showed that, for the average-risk population, higher specificity of Lugol's iodine (> 40%) and lower specificity of HRME (< 70%) could make Lugol's iodine screening cost-effective. For the high-risk population, the results of the model were not substantially affected by varying the follow-up rate after Lugol's iodine screening, Lugol's iodine test characteristics (sensitivity and specificity), or HRME specificity. CONCLUSION The incorporation of HRME into an ESCC screening program could be cost-effective in China. Larger studies of HRME performance are needed to confirm these findings.

Abstract
AIM To evaluate predictors of allogenic blood transfusion requirements in patients undergoing minimal invasive oesophagectomy at a tertiary high volume centre for oesophago-gastric surgery. METHODS Retrospective analysis of all patients undergoing minimal access oesophagectomy in our department between January 2010 and December 2011. Patients were divided into two groups depending on whether they required a blood transfusion at any time during their index admission. Factors that have been shown to influence perioperative blood transfusion requirements in major surgery were included in the analysis. Binary logistic regression analysis was performed to determine the impact of patient and perioperative characteristics on transfusion requirements during the index admission. RESULTS A total of 80 patients underwent minimal access oesophagectomy, of which 61 patients had a laparoscopic assisted oesophagectomy and 19 patients had a minimal invasive oesophagectomy. Perioperative blood transfusion was required in 28 patients at any time during hospital admission. On binary logistic regression analysis, a lower preoperative haemoglobin concentration (p < 0.01), suffering a significant complication (p < 0.005) and laparoscopic assisted oesophagectomy (p < 0.05) were independent predictors of blood transfusion requirements. DISCUSSION It has been reported that requirement for blood transfusion can affect long-term outcomes in oesophageal cancer resection. Two factors which could be addressed preoperatively; haemoglobin concentration and type of oesophageal resection, may be valuable in predicting blood transfusions in patients undergoing minimally invasive oesophagectomy. CONCLUSION Our analysis revealed that preoperative haemoglobin concentration, occurrence of significant complications and type of minimal access oesophagectomy predicted blood transfusion requirements in the patient population examined.

Abstract
BACKGROUND Endoscopic surveillance for non-dysplastic Barrett's esophagus (BE) is contentious and its cost effectiveness unclear. OBJECTIVE To perform an economic analysis of endoscopic surveillance strategies. DESIGN Cost-utility analysis by using a simulation Markov model to synthesize evidence from large epidemiologic studies and clinical data for surveillance, based on international guidelines, applied in a coordinator-managed surveillance program. SETTING Tertiary care hospital, South Australia. PATIENTS A total of 2040 patient-years of follow-up. INTERVENTION (1) No surveillance, (2) 2-yearly endoscopic surveillance of patients with non-dysplastic BE and 6-monthly surveillance of patients with low-grade dysplasia, (3) a hypothetical strategy of biomarker-modified surveillance. MAIN OUTCOME MEASUREMENTS U.S. cost per quality-adjusted life year (QALY) ratios. RESULTS Compared with no surveillance, surveillance produced an estimated incremental cost per QALY ratio of $60,858. This was reduced to $38,307 when surveillance practice was modified by a hypothetical biomarker-based strategy. Sensitivity analyses indicated that the likelihood that surveillance alone was cost-effective compared with no surveillance was 16.0% and 60.6% if a hypothetical biomarker-based strategy was added to surveillance, at an acceptability threshold of $100,000 per QALY gained. LIMITATIONS Treatment options for BE that overlap those for symptomatic GERD were omitted. CONCLUSION By using best available estimates of the malignant potential of BE, endoscopic surveillance of patients with non-dysplastic BE is unlikely to be cost-effective for the majority of patients and depends heavily on progression rates between dysplasia grades. However, strategies that modify surveillance according to cancer risk might be cost-effective, provided that high-risk individuals can be identified and prioritized for surveillance.

Abstract
Data suggest that aspirin, statins, or a combination of the two drugs may lower the progression of Barrett's esophagus to esophageal adenocarcinoma. However, aspirin is associated with potential complications such as gastrointestinal bleeding and hemorrhagic stroke, and statins are associated with myopathy. We developed a simulation disease model to study the effectiveness and cost effectiveness of aspirin and statin chemoprevention against esophageal adenocarcinoma. A decision analytic Markov model was constructed to compare four strategies for Barrett's esophagus management; all regimens included standard endoscopic surveillance regimens: (i) endoscopic surveillance alone, (ii) aspirin therapy, (iii) statin therapy, and (iv) combination therapy of aspirin and statin. Endpoints evaluated were life expectancy, quality-adjusted life years (QALY), costs, and incremental cost-effectiveness ratios (ICER). Sensitivity analysis was performed to determine the impact of model input uncertainty on results. Assuming an annual progression rate of 0.33% per year from Barrett's esophagus to esophageal adenocarcinoma, aspirin therapy was more effective and cost less than (dominated) endoscopic surveillance alone. When combination therapy was compared with aspirin therapy, the ICER was $158,000/QALY, which was above our willingness-to-pay threshold of $100,000/QALY. Statin therapy was dominated by combination therapy. When higher annual cancer progression rates were assumed in the model (0.5% per year), combination therapy was cost-effective compared with aspirin therapy, producing an ICER of $96,000/QALY. In conclusion, aspirin chemoprevention was both more effective and cost less than endoscopic surveillance alone. Combination therapy using both aspirin and statin is expensive but could be cost-effective in patients at higher risk of progression to esophageal adenocarcinoma.

Abstract
BACKGROUND & AIMS Radiofrequency ablation (RFA) reduces the risk of esophageal adenocarcinoma (EAC) in patients with Barrett's esophagus (BE) with high-grade dysplasia (HGD), but its effects in patients without dysplasia are debatable. We analyzed the effectiveness and cost effectiveness of RFA for the management of BE. METHODS We constructed a decision analytic Markov model. We conducted separate analyses of hypothetical cohorts of patients with BE with dysplasia (HGD or low-grade [LGD]) and without dysplasia. In the analysis of the group with HGD, we compared results of initial RFA with endoscopic surveillance with surgery when cancer was detected. In analyzing the group with LGD or no dysplasia, we compared 3 strategies: endoscopic surveillance with surgery when cancer was detected (S1), endoscopic surveillance with RFA when HGD was detected (S2), and initial RFA followed by endoscopic surveillance (S3). RESULTS Among patients with HGD, initial RFA was more effective and less costly than endoscopic surveillance. Among patients with LGD, when S3 was compared with S2, the incremental cost-effectiveness ratio was $18,231/quality-adjusted life-year, assuming an annual rate of progression rate from LGD to EAC of 0.5%/year. For patients without dysplasia, S2 was more effective and less costly than S1. In a comparison of S3 with S2, the incremental cost-effectiveness ratios were $205,500, $124,796, and $118,338/quality-adjusted life-year using annual rates of progression of no dysplasia to EAC of 0.12%, 0.33%, or 0.5% per year, respectively. CONCLUSIONS By using updated data, initial RFA might not be cost effective for patients with BE without dysplasia, within the range of plausible rates of progression of BE to EAC, and be prohibitively expensive, from a policy perspective. RFA might be cost effective for confirmed and stable LGD. Initial RFA is more effective and less costly than endoscopic surveillance in HGD.

Abstract
Background Health-related quality of life studies among adults with type 2 diabetes mellitus, using the EQ-5D, have been short term and have not assessed change over years. This study assessed the change in health status and health-related quality of life over 5 years among individuals with and without diabetes. Methods Respondents to the US Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) completed the EuroQol-5D (EQ-5D) at baseline (2004) and 5 years later (2009). Visual analog scale (VAS) score and health index score were computed at baseline and year 5, and the change over 5 years was measured for individuals with type 2 diabetes mellitus (T2DM) and those without diabetes, and T2DM adults with and without diabetic complications. Linear regression models were used to determine change in EQ-5D score, controlling for age, gender, race, education, household income, and body mass index (BMI). Results There was significantly greater decline in the EQ-5D index score in the T2DM group (-0.031 [SD 0.158]), compared with those without diabetes (-0.016 [0.141], p = 0.001). Compared with respondents without diabetes, those with T2DM had a larger reduction in EQ-5D index score, after controlling for demographics (p = 0.001). EQ-5D VAS score declined over 5 years for both groups: -1.42 (18.1) for the T2DM group, and -0.63 (15.8) for the group without diabetes, but the between-group difference was not significant either before (p = 0.09) or after (p = 0.12), controlling for demographics. T2DM respondents with diabetic complications had a greater decline in EQ-5D scores than T2DM respondents without complications (p < 0.05). Conclusion Over a 5-year period, health status of respondents with T2DM declined significantly compared with those with no diabetes, indicating that the burden of the disease has a long-term detrimental impact. This decline in health status is likely to impact utility scores (fewer quality-adjusted life years) for economic evaluations.

Abstract
OBJECTIVE This study aims to synthesize cost and health outcomes for current treatment pathways for esophageal adenocarcinoma and high-grade dysplasia (HGD) and to model comparative net clinical and economic benefits of alternative management scenarios. METHODS A decision-analytic model of real-world practices for esophageal adenocarcinoma treatment by tumor stage was constructed and validated. The model synthesized treatment probabilities, survival, quality of life, and resource use extracted from epidemiological datasets, published literature, and expert opinion. Comparative analyses between current practice and five hypothetical scenarios for modified treatment were undertaken. RESULTS Over 5 years, outcomes across T stage ranged from 4.06 quality-adjusted life-years and costs of $3,179 for HGD to 1.62 quality-adjusted life-years and costs of $50,226 for stage T4. Greater use of endoscopic mucosal resection for stage T1 and measures to reduce esophagectomy mortality to 0-3 % produced modest gains, whereas a 20 % reduction in the proportion of patients presenting at stage T3 produced large incremental net benefits of $4,971 (95 % interval, $1,560-8,368). CONCLUSION These findings support measures that promote earlier diagnosis, such as developing risk assessment processes or endoscopic surveillance of Barrett's esophagus. Incremental net monetary benefits for other strategies are relatively small in comparison to predicted gains from early detection strategies.

Abstract
BACKGROUND Colon cancer screening with colonoscopy is an accepted strategy; however, there are limited data regarding the cost-effectiveness of screening for upper GI cancers (esophageal adenocarcinoma with its premalignant precursor Barrett's esophagus, esophageal squamous cell cancer, gastric adenocarcinoma) in the United States. OBJECTIVE To evaluate the cost-effectiveness of screening the general population for upper GI cancers by performing an upper endoscopy at the time of screening colonoscopy. DESIGN Decision analysis. SETTING Third-party-payer perspective with a time horizon of 30 years or until death. PATIENTS This study involved 50-year-old patients already undergoing screening colonoscopy. INTERVENTION Comparison of two strategies: performing and not performing a screening upper endoscopy at the time of screening colonoscopy. MAIN OUTCOME MEASUREMENTS Incremental cost-effectiveness ratio (ICER). RESULTS One-time screening for the general population at the age of 50 for upper GI cancers required $115,664 per quality-adjusted life year (QALY) compared with no screening or surveillance. A strategy of screening and surveillance for Barrett's esophagus required only $95,559 per QALY saved. In 1-way sensitivity analyses, the prevalence rates of esophageal adenocarcinoma, esophageal squamous cell cancer, or gastric adenocarcinoma would have to increase by 654%, 1948%, and 337%, respectively, to generate an ICER of less than $50,000 per QALY. LIMITATIONS Omission of premalignant conditions for squamous cell cancer and gastric adenocarcinoma. CONCLUSION The ICER for screening the general population for upper GI cancers with endoscopy remains high, despite accounting for reduced endoscopy costs and the combined benefits of detecting early esophageal adenocarcinoma, esophageal squamous cell cancer, and gastric adenocarcinoma. However, the ICER compares favorably with commonly performed screening strategies for other cancers.

Abstract
Incidence of esophageal cancer (EC) is rising more rapidly in the Western world than that of any other cancer. Despite advances in therapy, more than 50% of patients have incurable disease at the time of presentation. This precludes curative treatment and makes palliative treatment a more realistic option for most of these patients. Dysphagia is the predominant symptom in more than 70% of patients with EC and although several management options have been developed in recent years to palliate this symptom, the optimum management is not established. Self-expanding metal stents (SEMS) are a well-established palliation modality for dysphagia in such patients. Health-related quality of life (HRQoL) is becoming a major issue in the evaluation of any therapeutic or palliative intervention. To date, only a few published studies can be found on Medline examining HRQoL in patients with advanced EC treated with SEMS implantation. The aim of this study was to review the impact on HRQoL of SEMS implantation as palliative treatment in patients with EC. All Medline articles regarding HRQoL in patients with advanced EC, particularly those related to SEMS, were reviewed. In most studies, relief of dysphagia was the only aspect of HRQoL being measured and SEMS implantation was compared with other palliative treatments such as brachytherapy and laser therapy. SEMS insertion provides a swift palliation of dysphagia compared to brachytherapy and no evidence was found to suggest that stent implantation is different to laser treatment in terms of improving dysphagia, recurrent dysphagia and better HRQoL, although SEMS insertion has a better technical success rate and also reduces the number of repeat interventions.

Abstract
BACKGROUND In the UK, oesophagectomy is the current recommendation for patients with persistent high-grade dysplasia in Barrett's oesophagus. Radiofrequency ablation is an alternative new technology with promising early trial results. AIM To undertake a cost-utility analysis comparing these two strategies. METHODS We constructed a Markov model to simulate the natural history of a cohort of patients with high-grade dysplasia in Barrett's oesophagus undergoing one of two treatment options: (i) oesophagectomy or (ii) radiofrequency ablation followed by endoscopic surveillance with oesophagectomy for high-grade dysplasia recurrence or persistence. RESULTS In the base case analysis, radiofrequency ablation dominated as it generated 0.4 extra quality of life years at a cost saving of £1902. For oesophagectomy to be the most cost-effective option, it required a radiofrequency ablation treatment failure rate (high-grade dysplasia persistence or progression to cancer) of >44%, or an annual risk of high-grade dysplasia recurrence or progression to cancer in the ablated oesophagus of >15% per annum. There was an 85% probability that radiofrequency ablation remained cost-effective at the NICE willingness to pay threshold range of £20 000-30 000. CONCLUSION Radiofrequency ablation is likely to be a cost-effective option for high-grade dysplasia in Barrett's oesophagus in the UK.

Abstract
BACKGROUND & AIMS Recommendations for patients with Barrett's esophagus (BE) include endoscopic surveillance with esophagectomy for early-stage cancer, although new technologies to ablate dysplasia and metaplasia are available. This study compares the cost utility of ablation with that of endoscopic surveillance strategies. METHODS A decision analysis model was created to examine a population of patients with BE (mean age 50), with separate analyses for patients with no dysplasia, low-grade dysplasia (LGD), or high-grade dysplasia (HGD). Strategies compared were no endoscopic surveillance; endoscopic surveillance with ablation for incident dysplasia; immediate ablation followed by endoscopic surveillance in all patients or limited to patients in whom metaplasia persisted; and esophagectomy. Ablation modalities modeled included radiofrequency, argon plasma coagulation, multipolar electrocoagulation, and photodynamic therapy. RESULTS Endoscopic ablation for patients with HGD could increase life expectancy by 3 quality-adjusted years at an incremental cost of <$6,000 compared with no intervention. Patients with LGD or no dysplasia can also be optimally managed with ablation, but continued surveillance after eradication of metaplasia is expensive. If ablation permanently eradicates >or=28% of LGD or 40% of nondysplastic metaplasia, ablation would be preferred to surveillance. CONCLUSIONS Endoscopic ablation could be the preferred strategy for managing patients with BE with HGD. Ablation might also be preferred in subjects with LGD or no dysplasia, but the cost effectiveness depends on the long-term effectiveness of ablation and whether surveillance endoscopy can be discontinued after successful ablation. As further postablation data become available, the optimal management strategy will be clarified.

Abstract
An accurate assessment of health-related quality of life (QoL) in patients with oesophageal or gastric cancer (OGC) is essential to inform clinical decisions by providing insights into patients' experiences of the impact of the disease and its treatments on physical, social and emotional health. Robust QoL questionnaires have been developed and validated in the past decade to measure the QoL of OGC patients. Baseline QoL variables are also prognostic for survival in patients with oesophageal cancer or metastatic gastric cancer. This article reviews the impact of surgery and reconstructive techniques, as well as of adjuvant and palliative treatments on the QoL of patients with OGC.

Abstract
OBJECTIVE There are few prospective data on the effects of prolonged intensive care unit stay on the quality of life and long-term survival of a homogeneous patient population. Therefore, the aims of this prospective study were a) to describe the quality of life in patients after having a transthoracic esophageal resection; and b) to analyze the influences of a prolonged intensive care unit stay on quality of life and survival in patients after esophageal cancer resection who survived to hospital discharge. DESIGN Prospective study. SETTING Medical center. PATIENTS The study population consisted of 109 patients undergoing a transthoracic resection for adenocarcinoma of the middistal esophagus or gastric cardia between April 1994 and February 2000. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A comparison was made between patients staying <or=5 days vs. >or=6 days in the intensive care unit and also <or=2 days vs. >or=14 days. Quality of life was assessed in all patients by mailed self-report questionnaires at baseline (preoperatively), at 5 wks, and at 3, 6, 9, 12, 18, 24, 30, and 36 months after surgery. Daily physical, emotional, and social functioning was assessed with the generic Medical Outcome Studies Short Form-20. Disease-specific quality of life was measured by an adapted Rotterdam Symptom Check List. Quality of life data were gathered between July 1994 and March 2003. Five of the 109 patients died in the hospital and were excluded from the analysis. All five of them were in the intensive care unit >or=6 days. Of the remaining 104 patients, 92 provided baseline scores. The data of the 92 patients were used for the quality of life analyses. For the clinicopathologic and survival analysis, the data of 104 hospital survivors were used. Patients spent a median of 5.5 days (range 0-71) in the intensive care unit. The Medical Outcome Studies Short Form-20 and the Rotterdam Symptom Check List measurements showed no clear differences in long-term quality of life between patients after a short vs. a prolonged postoperative intensive care unit period. The median overall survival in all patients was 2.0 yrs (range 0.1-8.0). Median overall survival in patients staying in the intensive care unit <or=5 days was 1.9 yrs (range 0.3-7.4 yrs) vs. 2.7 yrs (range 0.9-7.2 yrs) in patients staying >or=6 days (p = .9, log-rank test). Median overall survival in patients staying in the intensive care unit <or=2 days was 1.7 yrs (range 1.2-2.6 yrs) vs. 2.0 yrs (range 0.2-3.8 yrs) in patients staying >or=14 days (p = .74, log-rank test). CONCLUSIONS For patients who survived to hospital discharge after transthoracic esophagectomy, there was no difference in long-term quality of life or survival between those submitted to the intensive care unit for a short period vs. a long period.

Abstract
Objectives: The convergent validity between utility assessment methods was assessed.Methods: Investigated were patients with esophageal cancer treated surgically with curative intent. Patients were interviewed in a period from 3 to 12 months after surgical resection. Patients evaluated their actual health and seven other states. Visual analogue scale (VAS) and standard gamble (SG) utilities were obtained for the health states in an interview. Patients also indicated whether or not they preferred death to living in a health state (worse than dead [WTD] preferences).Results: Fifty patients completed the interview. Convergent validity was excellent at the aggregate and individual level. However, the relation between VAS and SG differed strongly across individuals. On a scale from 0 (dead) to 100 (perfect health), SG scores were lower for patients with WTD preferences (mean difference d=35; p=.002); however, VAS scores did not vary by WTD preferences.Conclusions: In general, there is good agreement between VAS and SG measures, although patients disagree about how the VAS and SG are related. The standard gamble varied by WTD preferences, however, the VAS did not.

Abstract
BACKGROUND Multiple treatment strategies for subjects with high grade dysplasia (HGD) in Barrett's oesophagus (BO) have been suggested. However, it is unclear which of these strategies provides the greatest life expectancy, and the costs associated with the management strategies are unknown. AIM To compare the efficacy and cost effectiveness of competing management strategies for BO with HGD. METHODS We created a decision analysis model in Data 4.0 to assess possible treatment strategies for BO with HGD. The strategies included: (1) no preventative strategy, (2) elective surgical oesophagectomy, (3) endoscopic ablation, and (4) surveillance endoscopy. The base case was a healthy 50 year old White male with an initial diagnosis of BO with HGD. The model allowed for complications of surgery, including death. Ablative therapy could cause stricture or perforation. Pathological misinterpretation was allowed, and modelled after reported rates. Estimates were derived from the literature for the rate of progression of HGD to cancer and for complication rates for the various treatment modalities. The endoscopic ablation arm was modelled as photodynamic therapy. Sensitivity analyses were performed over a wide range of cancer incidences, complication rates, and procedure costs. RESULTS Endoscopic ablation was the most effective strategy, yielding 15.5 discounted quality adjusted life years (dQALY), compared with 15.0 for endoscopic surveillance and 14.9 for oesophagectomy. No preventative strategy was the most inexpensive option, yielding an average cost per quality adjusted life year of US dollars 54 (44) per dQALY, but resulted in high rates of cancer. Endoscopic surveillance dominated oesophagectomy, being both less costly and more effective. The condition of extended dominance occurred when comparing endoscopic ablation to endoscopic surveillance because, although the total costs of ablation were greater than those of surveillance, it was less expensive to buy an additional life year using endoscopic ablation than endoscopic surveillance. The incremental cost effectiveness ratio when moving from no therapy to ablative therapy was a reasonable US dollars 25 621/dQALY (21 009/dQALY). Sensitivity analysis demonstrated that when yearly rates of progression to cancer from HGD exceeded 30%, oesophagectomy became the most cost effective option. CONCLUSIONS A strategy of endoscopic ablation provided the longest quality adjusted life expectancy for BO with HGD. Although endoscopic surveillance was less expensive than endoscopic ablation, it was associated with shorter survival. Optimal utilisation of healthcare resources may be achieved with endoscopic ablative therapy for BO with HGD.

Abstract
BACKGROUND Photodynamic therapy appears to be effective in ablating high-grade dysplasia in Barrett's esophagus. Our aim was to identify the most effective and cost-effective strategy for managing high-grade dysplasia in Barrett's esophagus without associated endoscopically visible abnormalities. METHODS By using decision analysis, the lifetime costs and benefits of 4 strategies for which long-term data exist were estimated by us: esophagectomy, endoscopic surveillance, photodynamic therapy, followed by esophagectomy for residual high-grade dysplasia; and photodynamic therapy followed by endoscopic surveillance for residual high-grade dysplasia. It was assumed by us that there was a 30% prevalence of cancer in high-grade dysplasia patients and a 77% efficacy of photodynamic therapy for high-grade dysplasia and early cancer. RESULTS Esophagectomy cost 24,045 dollars, with life expectancy of 11.82 quality-adjusted life years. In comparison, photodynamic therapy followed by surveillance for residual high-grade dysplasia was the most effective strategy, with a quality-adjusted life expectancy of 12.31 quality-adjusted life years, but it also incurred the greatest lifetime cost (47,310 dollars) for an incremental cost-effectiveness of 47,410 dollars/quality-adjusted life years. The results were sensitive to post-surgical quality of life and survival, and to cancer prevalence if photodynamic therapy efficacy for cancer was less than 50%. CONCLUSIONS Photodynamic therapy followed by endoscopic surveillance for residual high-grade dysplasia appears to be cost effective compared with esophagectomy for patients diagnosed with high-grade dysplasia in Barrett's esophagus. Clinical trials directly comparing these strategies are warranted.

Abstract
Objectives Major depressive disorder (MDD) is a prevalent psychiatric disorder associated with impaired patient functioning and reductions in health-related quality of life (HRQL). The present study describes the impact of MDD on patients' HRQL and examines preference-based health state differences by patient features and clinical characteristics. Methods 95 French primary care practitioners recruited 250 patients with a DSM-IV diagnosis of MDD for inclusion in an eight-week follow-up cohort. Patient assessments included the Montgomery Asberg Depression Rating Scale (MADRS), the Clinical Global Impression of Severity (CGI), the Short Form-36 Item scale (SF-36), the Quality of Life Depression Scale (QLDS) and the EuroQoL (EQ-5D). Results The mean EQ-5D utility at baseline was 0.33, and 8% of patients rated their health state as worse than death. There were no statistically significant differences in utilities by demographic features. Significant differences were found in mean utilities by level of disease severity assessed by CGI. The different clinical response profiles, assessed by MADRS, were also revealed by EQ-5D at endpoint: 0.85 for responders remitters, 0.72 for responders non-remitter, and 0.58 for non-responders. Even if HRQL and EQ-5D were moderately correlated, they shared only 40% of variance between baseline and endpoint. Conclusions Self-reported patient valuations for depression are important patient-reported outcomes for cost-effectiveness evaluations of new antidepressant compounds and help in further understanding patient compliance with antidepressant treatment.
