Claudia Henschke is a staunch supporter of CT scans for lung cancer screening. As a radiologist, this is understandable and she stands to benefit financially if CT scans were widely accepted and covered by insurance companies.

Her zealotry has colored her research, as studies in the NEJM and The Oncologist have been called into question. In this editorial in the latter journal (via MedPage Today), an audit of her work is called for:

We have previously called for an audit and now more than ever, it is in the interests of all concerned, including the authors, the sponsors (i.e., National Cancer Institute, American Cancer Society, as well as an independent foundation that derived its major support from a tobacco company) that an impartial audit be conducted expeditiously.
