ABSTRACT
OBJECTIVES:
Intensity-modulated radiation therapy (IMRT) has been rapidly adopted for the treatment of head and neck cancer. Limited comparative effectiveness data suggest that IMRT reduces the incidence of xerostomia and improves quality of life. We assess the cost of IMRT versus the older conventional radiation therapy (CRT) relative to other potential drivers of cost in patients with head and neck cancer.METHODS:
We compared patients treated with definitive radiation with or without chemotherapy for squamous cell carcinoma of the head and neck treated between 2000 and 2009. IMRT-treated patients were matched to CRT-treated patients by site, stage, and smoking status. Itemized billing charges were obtained for each patient and used to estimate cost using the Medicare fee schedule. Multivariate analysis was used to assess the influence of demographic, clinical, and treatment variables on total, pretreatment, during treatment, and follow-up costs.RESULTS:
Models indicate that compared with CRT, IMRT was associated with, on average, a $5881 increase in total costs (P=0.043), a $1700 decrease in pretreatment costs (P=0.014), a $4768 increase in costs during treatment (P=0.004), and no significant difference in follow-up costs. Positron emission tomography scans, cancer recurrence, and comorbidity were also associated with higher total costs in this sample.CONCLUSIONS:
Use of IMRT relative to CRT was strongly correlated with higher total costs, but disease control, patient comorbidity, and use of positron emission tomography also had significant effects on overall costs. Cost-effectiveness models should be developed to assess whether the potential benefits of IMRT are worth the associated investment.
