This page illustrates, for training and educational purposes, how the published PanCan/Brock University model by McWilliams et al. (New England Journal of Medicine, 2013;369:910‑9) combines variables into a probability estimate. Enter example values to see how each variable affects the calculation — this is a teaching illustration of the published formula, not a tool for evaluating a specific patient.
Brockscore.com is intended exclusively for use by physicians, pulmonologists, radiologists, and other qualified healthcare professionals. It is not a medical device and does not in any way replace clinical judgment, multidisciplinary review, or applicable guidelines (e.g. Fleischner Society, BTS).
The calculation is based on the published Brock/PanCan model (McWilliams A, Tammemagi MC, Mayo JR, et al. Probability of Cancer in Pulmonary Nodules Detected on First Screening CT. N Engl J Med. 2013;369(10):910‑919). Despite careful implementation, it cannot be guaranteed that the output is at all times error-free, up to date, or complete.
