Abstract
Objectives:18F-FDG-PET/CT is accurate in detecting distant metastases (DM) in breast cancer patients scheduled for neoadjuvant chemotherapy. If DMs are screen-detected in an early phase, morbidity and mortality may be reduced. Because 18F-FDG-PET/CT comes at a significant cost, we compared its expected cost-effectiveness in stage II/III breast cancer patients of the UK, the US and the Netherlands (NL) vs. the gold-standard (X-thorax/liver sonography/bone scan (UK/NL) and CT-thorax-abdomen/bone scan (US)).
Methods: A time-dependent Markov model compared expected Life Year (LY) and cost/Quality-adjusted Life Year (QALY) gained in four breast cancer subtypes (ER-/HER2+;ER+/HER2+;ER-/HER2-;ER+/HER2-) over a 5-year time horizon from a hospital perspective. Sensitivity and specificity of imaging and type of systemic and local treatments were derived from the Netherlands Cancer Institute. Epidemiological, survival and utility data were estimated from literature or informed by expert assumptions. Costs (2013) were derived from national tariffs (UK and NL), and from the Centres for Medicaid and Medicare Services (US).
Results: 18F-FDG-PET/CT is more sensitive (53% vs. 15%) and specific (97% vs. 94%) than the gold-standard. LYs and QALYs gained were similar across subtypes, ranging from 0.025 to 0.027 and 0.0037 to 0.0044 respectively. In all countries, ER+HER2+ was the least and ER+HER2- the most costly group. 18F-FDG-PET/CT is expected to be cost-effective in the NL and the US (with highest ICERs of €165/QALY in ER+/HER2+ and $750 in ER-HER2+), with probabilities of cost-effectiveness ranging from 46-52% and 62-72% respectively, but not in the UK, with a 66-75% probability, depending on tumor subtype.
Conclusions: Using 18F-FDG-PET/CT for DM screening in stage II/III breast cancer is expected to result in incremental QALY gains in all subtypes and countries. Due to costs differences between countries, 18F-FDG-PET/CT is expected to be cost-effective in the US and the NL, but not in the UK.
