6593 Background: Female childhood HL survivors treated with ≥10 Gy of chest radiation are at high risk of developing BC. The Children’s Oncology Group (COG) guidelines recommend lifetime annual mammography (MAM) and breast Magnetic Resonance Imaging (MRI) starting 8y after chest radiation or age 25, whichever is later, and clinical breast examination (CBE) annually from puberty and semiannually from age 25. Initial model results suggest that CBE adds no survival benefit in this cohort. Digital breast tomosynthesis (DBT) is increasingly replacing digital MAM in clinical practice. Here, we present the efficacy and cost-effectiveness of COG’s imaging-based screening recommendations. Methods: Life-years (LYs), quality-adjusted LYs (QALYs), BC mortality, and costs (2017 U.S.$) were estimated from simulating the lifetimes of 5-million chest-irradiated 25y old HL survivors who underwent BC screening with each of the following strategies: annual digital MAM, MRI, MAM+MRI, annual DBT or DBT+MRI from age 25 onward. Treatment-related BC risk (in-situ and invasive) and non-BC mortality were estimated from female 5y HL survivors in the Childhood Cancer Survivor Study and from U.S. population rates. Test sensitivity was 70-74% for MAM (based on prior HL studies) and 89% for DBT and MRI (based on women at high risk of de novo BC). Costs and quality of life weights were obtained from medical literature. Results: For HL survivors with no screening, lifetime BC risk was 42.7% and BC mortality was 18.1%. BC risk and non-BC mortality were, respectively, 7.4- and 5.2-fold higher at age 50 in HL survivors relative to the general population. Screening at ages 25-74 had similar LY gain and BC mortality reduction compared to lifetime screening; hence, we focused on screening for ages 25-74. For all strategies screening provided LY gain of 0.34-0.47 and reduced BC mortality by 6.7-9.8% compared with no screening; incremental cost-effectiveness ratio (ICER), or cost per QALY gained, for MAM alone was $58,726 and for DBT alone was $62,989. ICER of adding MRI to MAM ($385,285) or to DBT ($513,358) indicated lower cost-effectiveness of supplemental MRI (Table). Conclusions: Annual screening at ages 25-74y in chest-irradiated HL survivors appears beneficial. Using $100K per QALY gained as cost-effectiveness threshold, annual MAM or DBT are more cost-effective, whereas adding MRI to MAM is less cost-effective.[Table: see text]

10028 Background: Female survivors of childhood HL treated with ≥10 Gy of chest radiation are at high risk for breast cancer (BC). The Children’s Oncology Group (COG) guidelines recommend CBE annually starting at puberty and then semiannually from age 25, plus lifetime annual mammography (MAM) and breast Magnetic Resonance Imaging (MRI) starting 8y after chest radiation or age 25, whichever is later. While imaging-based screening recommendations are largely consistent with US guidelines for women at high BC risk, only the COG guidelines recommend CBE. The benefits of lifetime CBE starting from puberty for life in chest-irradiated HL survivors is unknown. Methods: Life-years (LYs) and lifetime BC mortality risk were estimated from a simulated cohort of 5-million HL survivors using the data from 5y female survivors of HL in the Childhood Cancer Survivor Study (CCSS) treated with ≥10 Gy of chest radiation. The simulated cohort underwent annual MAM+MRI from age 25 for life, with and without annual CBE from age 11 (presumed age of puberty) to age 24 and with and without semiannual CBE from age 25 for life with 100% adherence. BC included in-situ and invasive BC. Treatment-related BC incidence and non-BC mortality risks were estimated from the CCSS data. Risks at age <25 were extrapolated from the CCSS estimates while risks beyond age 50 were extrapolated additionally using the US population rates. CBE sensitivity (17.8%, in-situ and invasive BC) and specificity (98%) and MAM+MRI sensitivity (84.2-86.0%, in-situ; 96.7-97.1%, invasive) and specificity (75.3%) were obtained from the medical literature. Results: The CCSS cohort included 1057 female HL survivors. BC (all invasive) developed in three patients at age <25 (ages: 23, 24, 24). In the simulated cohort receiving no screening, lifetime BC risk was 40.8% and BC mortality was 17.5%. HL survivors around age 50 were at a 7.4-fold higher risk of developing BC and a 5.2-fold higher risk of non-BC mortality when compared with the general population. Compared to no annual CBE for ages 11-24y, undergoing annual CBE did not increase gains in LYs or reduce lifetime BC mortality relative to no screening (Table). Among those who survived to age ≥25, undergoing semiannual CBE from age 25 for life compared to no semiannual CBE also resulted in little gain in LYs or reduction in lifetime BC mortality relative to no screening. Conclusions: Lifetime CBE starting at puberty in conjunction with MAM+MRI appears to add little survival benefits compared with no CBE, suggesting that COG guidelines may be revised without adverse effect on long-term outcomes for chest-irradiated female survivors of childhood HL.[Table: see text]

ObjectiveTo evaluate the cost-effectiveness of insertable cardiac monitors (ICMs) compared with standard of care (SoC) for detecting atrial fibrillation (AF) in patients at high risk of stroke (CHADS2 >2), using a UK National Health Service (NHS) perspective.MethodsUsing patient characteristics and clinical data from the REVEAL AF trial, a Markov model assessed the cost-effectiveness of detecting AF with an ICM compared with SoC. Costs and benefits were extrapolated across modelled patient lifetime. Ischaemic and haemorrhagic strokes, intracranial and extracranial haemorrhages and minor bleeds were modelled. Diagnostic and device costs were included, plus costs of treating stroke and bleeding events and costs of oral anticoagulants (OACs). Costs and health outcomes, measured as quality-adjusted life years (QALYs), were discounted at 3.5% per annum. One-way deterministic and probabilistic sensitivity analyses (PSA) were undertaken.ResultsThe total per-patient cost for ICM was £13 360 versus £11 936 for SoC (namely, annual 24 hours Holter monitoring). ICMs generated a total of 6.50 QALYs versus 6.30 for SoC. The incremental cost-effectiveness ratio (ICER) was £7140/QALY gained, below the £20 000/QALY acceptability threshold. ICMs were cost-effective in 77.4% of PSA simulations. The number of ICMs needed to prevent one stroke was 21 and to cause a major bleed was 37. ICERs were sensitive to assumed proportions of patients initiating or discontinuing OAC after AF diagnosis, type of OAC used and how intense the traditional monitoring was assumed to be under SoC.ConclusionsThe use of ICMs to identify AF in a high-risk population is cost-effective for the UK NHS.

Introduction: The burden of oral cancer is high in Hungary. Aim: To study the cost-effectiveness of potential oral cancer screening in Hungary. Method: Three strategies were compared: no introduction of screening, organized yearly screening for 40-year-old males in general medical practise, and opportunistic screening of high risk 40-year-old males in primary care. Local estimates of health utilities and costs of each health state and of the screening programmes were identified. The main outcomes were total costs, quality adjusted life years, and incremental cost-effectiveness ratios. Results: Depending on the efficacy of the treatments of precancerous lesions and the participation rate, screening strategies are cost-effective over a 15–20 year time course. The opportunistic screening of high risk people is more cost-effective than the other strategies. Conclusions: Opportunistic screening of high risk people would be cost-effective in Hungary. The uncertainty about the efficacy of the treatments of precancerous lesions requires more research to support evidence based health policy making. Orv. Hetil., 2016, 157(29), 1161–1170.

AbstractDual antiplatelet therapy (DAPT) with clopidogrel plus aspirin within 48 h of acute minor strokes and transient ischemic attacks (TIAs) has been indicated to effectively reduce the rate of recurrent strokes. However, the efficacy of clopidogrel has been shown to be affected by cytochrome P450 2C19 (CYP2C19) polymorphisms. Patients carrying loss-of-function alleles (LoFAs) at a low risk of recurrence (ESRS < 3) cannot benefit from clopidogrel plus aspirin at all and may have an increased bleeding risk. In order to optimize antiplatelet therapy for these patients and avoid the waste of medical resources, it is important to identify the subgroups that genuinely benefit from DAPT with clopidogrel plus aspirin through CYP2C19 genotyping. This study sought to assess the cost-effectiveness of CYP2C19 genotyping to guide drug therapy for acute minor strokes or high-risk TIAs in China. A decision tree and Markov model were constructed to evaluate the cost-effectiveness of CYP2C19 genotyping. We used a healthcare payer perspective, and the primary outcomes included quality-adjusted life years (QALYs), costs and the incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed to evaluate the robustness of the results. CYP2C19 genotyping resulted in a lifetime gain of 0.031 QALYs at an additional cost of CNY 420.13 (US$ 59.85), yielding an ICER of CNY 13,552.74 (US$ 1930.59) per QALY gained. Probabilistic sensitivity analysis showed that genetic testing was more cost-effective in 95.7% of the simulations at the willingness-to-pay threshold of CNY 72,100 (GDP per capita, US$ 10,300) per QALY. Therefore, CYP2C19 genotyping to guide antiplatelet therapy for acute minor strokes and high-risk TIAs is highly cost-effective in China.

Objective: To evaluate the cost-effectiveness of insertable cardiac monitors (ICMs) compared to standard of care (SoC) for detecting atrial fibrillation (AF) in patients at high risk of stroke (CHADS2 >2), in the US. Background: ICMs are a clinically effective means of detecting AF in high-risk patients, prompting the initiation of non-vitamin K oral anticoagulants (NOACs). Their cost-effectiveness from a US clinical payer perspective is not yet known. Methods: Using patient data from the REVEAL AF trial (n= 446, average CHADS2 score= 2.9), a Markov model estimated the lifetime costs and benefits of detecting AF with an ICM or with SoC (namely, intermittent use of electrocardiograms [ECGs] and 24-hour Holter monitors). Ischemic and hemorrhagic strokes, intra- and extra-cranial hemorrhages, and minor bleeds were modelled. Diagnostic and device costs were included, plus costs of treating stroke and bleeding events and of NOACs. Costs and health outcomes, measured as quality-adjusted life years (QALYs), were discounted at 3% per annum. One-way deterministic and probabilistic sensitivity analyses (PSA) were undertaken. Results: Lifetime per-patient cost for ICM was $58,132 vs. $52,019 for SoC. ICMs generated a total 7.75 QALYs vs. 7.59 for SoC, with 34 fewer strokes projected per 1,000 patients. The incremental cost-effectiveness ratio (ICER) was $35,452 per QALY gained. ICMs were cost-effective in 72% of PSA simulations, using a $50,000 per QALY threshold. Conclusions: The use of ICMs to identify AF in a high-risk population is likely to be cost-effective in the US healthcare setting.

Abstract Introduction: Though cure rates for childhood acute lymphoblastic leukemia (ALL) have improved significantly, outcomes for children with relapsed ALL remain poor. Novel immunotherapies have proved effective in relapsed disease. Blinatumomab, a bispecific T-cell engager targeting CD19, was recently shown to improve disease-free and overall survival among children with high-risk relapsed disease (Brown et al, 2021) prior to proceeding to stem cell transplant. Blinatumomab however also represents a significant cost burden to institutions and healthcare systems. Our objective was thus to determine the cost-effectiveness of blinatumomab vs. standard of care therapy among children with high-risk relapsed ALL. Methods: We used a childhood ALL-specific policy simulation model previously developed using real world clinical, healthcare utilization, and cost population-based data from Ontario, Canada, and restricted it to children with B-lineage ALL who relapsed with 18 months of their original diagnosis to capture a population of patients with high-risk relapse who survived their original month of re-induction chemotherapy. This model was combined with published data from the Children's Oncology Group randomized control study AALL1331 to estimate the long-term survival, healthcare costs and quality adjusted life years associated with two courses of blinatumomab vs. two courses of standard intensive chemotherapy, followed by stem cell transplant. Combining these two sources allowed for the creation of a multi-state survival model and the estimation of the impact of blinatumomab upon relapse and survival. Healthcare costs for the administration of blinatumomab or chemotherapy were sourced from administrative data, provincial formularies, and published sources. Lifetime costs and quality-adjusted life years were calculated while Monte Carlo simulation was used to propagate parameter uncertainty in the cost-effectiveness outcomes. All costs were calculated in Canadian dollars (CAD). Results: Blinatumomab was associated with on average higher life expectancy (43.4 years vs. 36.8 years) and a higher number of quality adjust life years [2.75 QALYs gained, 95 th confidence interval (95CI) -0.44 to 5.99] but higher costs (60,420 CAD, 95CI 26,794 - 94,047) compared to standard intensive chemotherapy. The incremental cost effectiveness ratio (ICER) associated with blinatumomab was 21,970 CAD/QALY gained. However, substantial uncertainty around model parameters resulted in wide confidence intervals around cost-effectiveness outcomes. Discussion: Initial evidence indicates that the use of blinatumomab in high-risk relapse of childhood ALL as compared to standard chemotherapy is associated with a cost-effectiveness ratio that is comparable to or lower than that associated with other interventions recently introduced in pediatric ALL, and represents a cost-effective intervention for this population. However, estimates are based on limited evidence; further research is necessary to better inform several model parameters and thereby decrease uncertainty in cost-effectiveness outcomes.

Bacillus Calmette–Guerin (BCG), the only available vaccine for tuberculosis (TB), has been applied for decades. The Indonesian government recently introduced a national TB disease control programme that includes several action plans, notably enhanced vaccination coverage, which can be strengthened through underpinning its favourable cost-effectiveness. We designed a Markov model to assess the cost-effectiveness of Indonesia’s current BCG vaccination programme. Incremental cost-effectiveness ratios (ICERs) were evaluated from the perspectives of both society and healthcare. The robustness of the analysis was confirmed through univariate and probabilistic sensitivity analysis (PSA). Using epidemiological data compiled for Indonesia, BCG vaccination at a price US$14 was estimated to be a cost-effective strategy in controlling TB disease. From societal and healthcare perspectives, ICERs were US$104 and US$112 per quality-adjusted life years (QALYs), respectively. The results were robust for variations of most variables in the univariate analysis. Notably, the vaccine’s effectiveness regarding disease protection, vaccination costs, and case detection rates were key drivers for cost-effectiveness. The PSA results indicated that vaccination was cost-effective even at US$175 threshold in 95% of cases, approximating the monthly GDP per capita. Our findings suggest that this strategy was highly cost-effective and merits prioritization and extension within the national TB programme. Our results may be relevant for other high endemic low- and middle-income countries.

Objective To compare the cost-effectiveness of sialendoscopy with gland excision for the management of submandibular gland sialolithiasis. Study Design Cost-effectiveness analysis. Setting Outpatient surgery centers. Methods A Markov decision model compared the cost-effectiveness of sialendoscopy versus gland excision for managing submandibular gland sialolithiasis. Surgical outcome probabilities were found in the primary literature. The quality of life of patients was represented by health utilities, and costs were estimated from a third-party payer’s perspective. The effectiveness of each intervention was measured in quality-adjusted life-years (QALYs). The incremental costs and effectiveness of each intervention were compared, and a willingness-to-pay ratio of $150,000 per QALY was considered cost-effective. One-way, multivariate, and probabilistic sensitivity analyses were performed to challenge model conclusions. Results Over 10 years, sialendoscopy yielded 9.00 QALYs at an average cost of $8306, while gland excision produced 8.94 QALYs at an average cost of $6103. The ICER for sialendoscopy was $36,717 per QALY gained, making sialendoscopy cost-effective by our best estimates. The model was sensitive to the probability of success and the cost of sialendoscopy. Sialendoscopy must meet a probability-of-success threshold of 0.61 (61%) and cost ≤$11,996 to remain cost-effective. A Monte Carlo simulation revealed sialendoscopy to be cost-effective 60% of the time. Conclusion Sialendoscopy appears to be a cost-effective management strategy for sialolithiasis of the submandibular gland when certain thresholds are maintained. Further studies elucidating the clinical factors that determine successful sialendoscopy may be aided by these thresholds as well as future comparisons of novel technology.

Background: The IMbrave 150 trial revealed that atezolizumab plus bevacizumab (atezo–bev) improves survival in patients with unresectable hepatocellular carcinoma (HCC) (1 year survival rate: 67.2% vs. 54.6%). We assessed the cost-effectiveness of atezo–bev vs. sorafenib as first-line therapy in patients with unresectable HCC from the US payer perspective. Methods: Using data from the IMbrave 150, we developed a Markov model to compare the lifetime cost and efficacy of atezo–bev as first-line systemic therapy in HCC with those of sorafenib. The main outcomes were life-years, quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratio (ICER). Results: Atezo–bev demonstrated a gain of 0.44 QALYs, with an additional cost of USD 79,074. The ICER of atezo–bev was USD 179,729 per QALY when compared with sorafenib. The model was most sensitive to the overall survival hazard ratio and body weight. If we assumed that all patients at the end of the IMbrave 150 trial were cured of HCC, atezo–bev was cost-effective (ICER USD 53,854 per QALY). However, if all patients followed the Surveillance, Epidemiology, and End Results data, the ICER of atezo–bev was USD 385,857 per QALY. Reducing the price of atezo–bev by 20% and 29% would satisfy the USD 150,000/QALY and 100,000/QALY willingness-to-pay threshold. Moreover, capping the duration of therapy to ≤12 months or reducing the dosage of bev to ≤10 mg/kg would render atezo–bev cost-effective. Conclusions: The long-term effectiveness of atezo–bev is a critical but uncertain determinant of its cost-effectiveness. Price reduction would favorably influence cost-effectiveness, even if long-term clinical outcomes were modest. Further studies to optimize the duration and dosage of therapy are warranted.

Abstract Background Previous studies have examined the impact of material financial hardship on cancer screening but without focusing on the psychological aspects of financial hardship. Purpose This study examined the effects of different types of financial anxiety on adherence to breast cancer screening in women at high risk of breast cancer. Adherence to cervical cancer screening was also examined to determine whether associations between financial anxiety and screening adherence were unique to breast cancer screening or more general. Methods Women (n = 324) aged 30–50 and at high risk for inherited breast cancer completed a survey on general financial anxiety, worry about affording healthcare, financial stigma due to cancer risk, and adherence to cancer screening. Multivariate analyses controlled for poverty, age, and race. Results More financial anxiety was associated with lower odds of mammogram adherence (odds ratio [OR] = 0.97, confidence interval [CI] = 0.94, 0.99), Pap smear adherence (OR = 0.98, CI = 0.96, 0.996), and clinical breast examination adherence (OR = 0.98, CI = 0.96, 0.995). More worry about affording healthcare was associated with lower odds of clinical breast examination adherence (OR = 0.95, CI = 0.91, 0.9992) but not mammogram or Pap smear adherence (p &gt; .05). Financial stigma due to cancer risk was associated with lower odds of Pap smear adherence (OR = 0.87, CI = 0.77, 0.97) but no other cancer screenings (p &gt; .07). Conclusions Financial anxiety may impede cancer screening, even for high-risk women aware of their risk status. Clinical interventions focused on social determinants of health may also need to address financial anxiety for women at high risk of breast cancer.
