Prostate Cancer Staging: TNM, Grade Groups, and Treatment Paths

TNM plus Grade Group

Prostate cancer staging pairs the AJCC TNM system with the Grade Group (derived from Gleason score) and baseline PSA. Together they drive risk stratification far better than T stage alone.

From stage to strategy

• Low risk may be appropriate for active surveillance rather than immediate treatment.
• Intermediate risk often involves surgery or radiation, sometimes with short-course androgen deprivation.
• High risk / locally advanced typically needs combined modality therapy and systemic treatment.

A consistent staging workflow keeps these thresholds explicit across cases.
