ABSTRACT: Background
Standard treatment for locally advanced esophageal cancer usually includes a combination of chemotherapy, radiation, and surgery. In squamous cell carcinoma (SCC), recent studies have indicated that esophagectomy after chemoradiation does not significantly improve survival but may reduce recurrence at the cost of treatment-related mortality. This study aims to evaluate the cost-effectiveness of chemoradiation with and without esophagectomy.Methods
We developed a decision tree and Markov model to compare chemoradiation therapy alone (CRT) versus chemoradiation plus surgery (CRT+S) in a cohort of 57-year-old male patients with esophageal SCC, over 25 years. We used information on survival, cancer recurrence, and side effects from a Cochrane meta-analysis of two randomized trials. Societal utility values and costs of cancer care (2017, USD) were from medical literature. To test robustness, we conducted deterministic (DSA) and probabilistic sensitivity analyses (PSA).Results
In our base scenario, CRT resulted in less cost for more quality-adjusted life years (QALYs) compared to CRT+S ($154 082 for 1.32 QALYs/patient versus $165 035 for 1.30 QALYs/patient, respectively). In DSA, changes resulted in scenarios where CRT+S is cost-effective at thresholds between $100 000-$150 000/QALY. In PSA, CRT+S was dominant 17.9% and cost-effective at willingness-to-pay of $150 000/QALY 38.9% of the time, and CRT was dominant 30.6% and cost-effective 61.1% of the time. This indicates that while CRT would be preferred most of the time, variation in parameters may change cost-effectiveness outcomes.Conclusions
Our results suggest that more data is needed regarding the clinical benefits of CRT+S for treatment of localized esophageal SCC, although CRT should be cautiously preferred.
