Abstract

The transparency and documentation of the peer review process have been discussed recently. Our position is that transparency is best achieved when peer review is a collaborative process, in which both parties are open-minded but both also realize that the study pathologist retains complete control over the findings (raw data) and over the content of the pathology report. For these reasons, we believe that histopathology raw data should be defined as the observations made by the study pathologist (printed and/or electronic formats) rather than as the tissue slides recommended by the Organisation for Economic Co-operation and Development (OECD). Also, because the study pathologist retains control over the histopathology raw data, any notes or tabulations of findings by the study pathologist and peer review pathologist during the peer review are interim notes and should not be included as an appendix to the pathology report though they may be retained if desired, as currently recommended. Because the histopathology raw data have not been created until completion of the peer review, the performance of a peer review should be documented in the study report, as currently recommended, but that it not be a GLP-compliant process.
