2611 scanned prostate biopsies from 460 patient cases sampled between 2015 and 2018. Annotation of clinical metadata and treatment decisions made in connection with biopsy sampling exist on case-level. Roughly 35% of the biopsies contain cancer. In-image annotations exists in macro images the form of ink markings from the clinical workflow.
Keywords: Prostate Cancer, Pathology.

Annotation
The cases are annotated with clinical data relevant for the treatment decision and the following treatment decision made in conjunction with the biopsy sampling. Each image is given an identifier which can be connected to the case by the case mapping file. Clinical data and treatment decisions have been extracted by manual medical records search. The information about treatment is what has been noted in conjunction with the diagnosis. Some cases contain missing data in some of the fields as the data wasn’t available. Some of the biopsies are resliced versions of another biopsy belonging to the same case. Together with the images macro-images of the biopsies exist with localized annotation of gleason grade and cancer detection as provided in the clinical workflow.
