BackgroundNivolumab in combination with chemotherapy significantly improves survival in patients with gastric/gastroesophageal junction (G/GEJ)/esophageal adenocarcinoma.The purpose of this study was to evaluate the cost-effectiveness of Nivolumab plus chemotherapy for G/GEJ/esophageal adenocarcinoma. MethodsA Markov model was developed on the basis of the US healthcare payers perspectives. We estimated the costs and summarised their effectiveness as quality-adjusted life-years (QALYs). One-way and probabilistic sensitivity analyses were conducted to explore the impact of uncertainties on the cost-effectivenesss results. ResultsThe incremental cost-effectiveness ratios (ICER) for Nivolumab plus chemotherapy($149636.97,1.24QALYs) verus chemotherapy($13941.06,0.75QALYs) is $135695.91 and the QALYs is 0.49. ConclusionsEvidence suggests that Nivolumab plus chemotherapy a for the first-line treatment of locally advanced or metastatic gastric/GEJ/oesophageal adenocarcinoma may be not a cost-effective choice.
