Here’s how the Gleason Score works: scale, types and what Biden has
The 82-year-old’s personal office announced on Sunday that he had been diagnosed with an “aggressive form” of prostate cancer.
Joe Biden has been diagnosed with an “aggressive form” of prostate cancer that has metastasized to the bone, his office said in a statement on Sunday.
The former U.S. president Biden, was diagnosed on after having experienced urinary symptoms, and he and his family are reviewing treatment options with doctors, the statement said.
A statement released by the president’s personal office said the cancer is “characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone.
The Pennsylvania native Biden will begin a series of PSA (prostate-specific antigen), tests, digital rectal exams, and biopsies with treatment initiated only if the cancer shows signs of progression.
A series of therapies are available and these will be selected according to the 82-year-old’s particular situation.
Gleason test
A statement released by the president’s personal office said the cancer is “characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone.
The Gleason Score is a system used to grade the aggressiveness of prostate cancer cells based on how they look under a microscope and is a key factor in determining the prognosis and guiding treatment decisions.
The Gleason score is a numerical value that reflects the grade of prostate cancer. It’s determined by adding together two grades, one for the most common cell pattern (primary grade) and one for the next most common cell pattern (secondary grade).
Grade Groups: The Gleason score is further categorized into grade groups (1-5), which provide a more general understanding of the cancer’s behavior.
Grade Group 1 (Gleason score 6 or lower): Low-grade cancer, likely to grow very slowly.
Grade Group 2 (Gleason score 7, 3+4): Medium-grade cancer, likely to grow and spread slowly.
Grade Group 3 (Gleason score 7, 4+3): Medium-grade cancer, likely to grow and spread at a moderate rate.
Grade Group 4 (Gleason score 8): High-grade cancer, likely to grow and spread quickly.
Grade Group 5 (Gleason score 9-10): High-grade cancer, likely to grow and spread quickly.
