Cancer Screening for Dermatomyositis: A Survey of Indirect Costs, Burden, and Patient Willingness to Pay.

Dermatomyositis (DM) is a rare idiopathic inflammatory myopathy (IIM) associated with an increased risk for malignancy. Although cancer screening is recommended, no consensus guidelines currently exist. Whole-body positron emission tomography/ computed tomography (PET/CT) has similar cost and efficacy to a more traditional conventional cancer screening panel (CSP). Our study sought to characterize patients' perspective of cancer screening and the indirect costs to patients. We conducted a survey of patients recently diagnosed with DM who were undergoing or had recently undergone a CSP. Patient values and indirect costs need to be considered in choosing a screening modality. This study contributes to a greater understanding of patients' experience of cancer screening in DM, which should be taken into consideration when developing consensus guidelines for cancer screening.
