Godoy et al reported a nomogram for predicting the risk of pelvic lymph node metastases in a male with prostate cancer. This can help to identify a patient who may benefit from a pelvic lymph node disssection. The authors are from Memorial Sloan-Kettering Cancer Center.
Patient selection: prostate cancer
Parameters:
(1) initial PSA in ng/mL
(2) clinical stage
(3) Gleason score on the biopsy

Interpretation:
• minimum score: 0
• maximum score: 204.5
• The higher the score the greater the risk of pelvic lymph node metastases.
