Collection and usage attributes | |
Guide for use: | Primary Gleason grade (a specific form of histopathological grade) refers to the tumour pattern which occupies the greatest area of tumour in sections from a needle core biopsy or radical prostatectomy specimen. This is assigned by a pathologist. Primary Gleason grades range from 1 to 5 and is an indicator of how likely it is that a tumour will spread. A low Gleason grade means the cancer tissue is similar to normal prostate tissue and the tumour is less likely to spread; a high Gleason grade means the cancer tissue is very different from normal and the tumour is more likely to spread. The primary Gleason grade is used in conjunction with the secondary Gleason grade to form the Gleason score (or sum). |

Collection methods: | To be sought from pathology reports or patient medical records. |
Comments: | A Gleason grade is a prognostic indicator of prostate cancer which may be used to guide treatment and assess whether appropriate treatment protocols have been used. |
