Prostate cancer 4+5 belongs to the Gleason classification, which means 4+5=9, indicating a high degree of malignancy.
Currently at home and abroad, Gleason grading system is recommended for pathological grading of prostate cancer. That is to say, prostate cancer tissues are divided into main grading area and secondary grading area, and the Gleason score of each area is 1~5. Gleason score is the sum of Gleason score of main grading area and secondary grading area, which forms the grading constant of cancer tissues.
The Gleason score, prostate-specific antigen (PSA) level and tumor stage are the most important indicators for determining treatment options and prognostic risk. Patients with a Gleason grade of 9 are at high risk and have a pathologic grade of G3-4, which is poorly differentiated or undifferentiated.
If prostate cancer is suspected or diagnosed, it is recommended to go to a regular hospital for a comprehensive assessment of the condition and follow the doctor’s instructions for treatment to avoid delays.
