title: Gleason’s Grading of Prostatic Adenocarcinoma: Inter-Observer Variation Among Seven Pathologists at a Tertiary Care Center in Oman
abstract: Prostatic adenocarcinoma is the commonest solid malignancy seen in Omani elderly males 60-80 years of age.
  The Gleason grade is the most widely used grading system for prostatic carcinoma and is recommended by the World
  Health Organization. A peer review was carried out at the Pathology Department of Sultan Qaboos University Hospital
  (SQUH), Oman, to assess the quality of reporting at the center. The aim of this study was to determine inter-observer
  variation among 7 pathologists working at a tertiary care center in Oman. A total of 47 consecutive prostatic biopsies
  were interdependently reviewed by seven pathologists and the results obtained were compared with each other and
  the original diagnosis. This peer review indicated a fair inter-observer agreement (0.482) among 7 pathologists in the
  department, with fair to moderate agreement when the results were compared to the reported diagnosis, comparable to
  the published literature. Dual and sub-specialty reporting are being instituted to improve the performance in this vital
  aspect of pathology.
