Correlation with risk groups for localized disease
|
I is "low risk" (PSA < 10, G = 6), IIA is "intermediate risk" (roughly, PSA 10-20, or G7 and PSA<20), IIB is "high risk" (T2c or PSA=20 or G=8).
|
|
|
Changes from 6th Edition
|
New stage groupings incorporate Gleason + PSA
Microscopic bladder neck invasion (previously T4) is now T3a |
