Cost-effectiveness analysis of salvage therapies in locoregional previously irradiated head and neck cancer.

ABSTRACT: BACKGROUND:The purpose of this study was to present our evaluation of the cost-effectiveness of salvage therapies for patients with recurrent head and neck cancer. METHODS:A Markov model was developed with 5 salvage treatment strategies: (1) platinum-based chemotherapy alone; (2) chemotherapy plus cetuximab; (3) stereotactic body radiotherapy (SBRT) alone; (4) SBRT plus cetuximab; and (5) intensity-modulated radiotherapy (IMRT) plus chemotherapy. Clinical parameters were obtained from comprehensive literature review and 2016 Medicare reimbursement. Strategies were compared using the incremental cost-effectiveness ratio (ICER), with effectiveness in quality-adjusted life years (QALYs), and evaluated with a willingness-to-pay (WTP) threshold of $100 000 per QALY gained. RESULTS:In the base case analysis, no treatment strategy was cost-effective at a WTP threshold. The most cost-effective therapy was SBRT alone with $150 866 per QALY gained. If median survival of SBRT alone was ?11 months, SBRT was considered to be cost-effective. CONCLUSION:None of the treatment strategies were cost-effective. However, SBRT-based reirradiation has potential to be cost-effective.

Project description:BackgroundTreatment options for patients with platinum-refractory, recurrent, metastatic head and neck squamous cell carcinoma (r/m HNSCC) are limited and prognosis is poor. The recent CheckMate 141 clinical trial demonstrated that nivolumab, an anti-programmed cell death protein 1 monoclonal antibody, was efficacious in extending the median overall survival (OS) in this patient population compared with standard therapies. We conducted a cost-effectiveness analysis to determine whether nivolumab is a cost-effective treatment in this patient population and examined various subgroups to determine for which, if any, the treatment is more cost-effective.Materials and methodsWe implemented a state transition model for HNSCC with a patient cohort who had tumor progression 6 months after the last dose of platinum-containing chemotherapy and compared the cost-effectiveness of nivolumab with docetaxel. Treatment effect estimates and adverse event rates were obtained from CheckMate 141. Costs, utilities, and other model inputs were gathered from published sources. We used a Canadian perspective, a 5-year time horizon, and a 1.5% discount rate for the analysis.ResultsNivolumab extended mean OS by 4 months compared with docetaxel and resulted in fewer treatment-related adverse events, producing an incremental effectiveness of 0.13 quality-adjusted life years (QALY). The incremental cost of treatment with nivolumab was $18,823. At a willingness-to-pay threshold of $100,000/QALY, nivolumab was not a cost-effective treatment option for r/m HNSCC, with an incremental cost-effectiveness ratio of $144,744/QALY. Nivolumab would be cost-effective if its price was reduced by 20%. Our subgroup analysis seemed to indicate that nivolumab might be cost-effective for tumors with expression of programmed death-ligand 1 >5%.ConclusionWe conclude that although nivolumab offers clinical benefit for the treatment of r/m HNSCC over current regimens, it is not cost-effective based on its list price. We have also established a value-based price estimate for nivolumab to be cost-effective in this patient population. Further study is required to draw a definitive conclusion on biomarkers for cost-effectiveness.Implications for practiceIn health care settings in which cost considerations are a constraint on choice of therapy, patient selection should be carefully considered to maintain efficiency in the system. Until a biomarker for response to therapy is identified for nivolumab, this medication is unlikely to be cost-effective for most patients with recurrent, metastatic head and neck squamous cell carcinoma.

Project description:ObjectiveThere is limited evidence regarding the economic effects of nutrition support in cancer patients. This study aims at investigating the cost-effectiveness profile of systematic oral nutritional supplementation (ONS) in head and neck cancer (HNC) patients undergoing radiotherapy (RT) and receiving nutritional counseling.MethodsA cost-effectiveness analysis based on a RCT was performed to estimate direct medical costs, life years gained (LYG) and Quality-Adjusted Life Years (QALY) for nutritional counseling with or without ONS at 5-month and 6-year follow up time. Value of information analysis was performed to value the expected gain from reducing uncertainty through further data collection.ResultsONS with nutritional counseling produced higher QALY than nutritional counseling alone (0.291 ± 0.087 vs 0.288 ± 0.087), however the difference was not significant (0.0027, P = 0.84). Mean costs were €987.60 vs €996.09, respectively in the treatment and control group (-€8.96, P = 0.98). The Incremental Cost Effectiveness Ratio (ICER) was -€3,277/QALY, with 55.4% probabilities of being cost-effective at a cost-effectiveness threshold of €30,000/QALY. The Expected Incremental Benefit was €95.16 and the Population Expected Value of Perfect Information was €8.6 million, implying that additional research is likely to be worthwhile. At a median 6-year follow up, the treatment group had a significantly better survival rate when adjusting for late effect (P = 0.039).ConclusionOur findings provide the first evidence to inform decisions about funding and reimbursement of ONS in combination with nutritional counseling in HNC patients undergoing RT. ONS may improve quality of cancer care at no additional costs, however further research on the cost-effectiveness of nutritional supplementation is recommended.Trial registrationClinicalTrials.gov: NCT02055833.
