The Han tables were developed by urologists Misop Han, M.D., Alan W. Partin, M.D., Ph.D., and Patrick C. Walsh, M.D., based on accumulated data from thousands of patients who had been treated for prostate cancer at the James Buchanan Brady Urological Institute at The Johns Hopkins Hospital. After using the Partin tables to predict the definitive pathological stage (the extent of cancer spread), men and their doctors may want to know the probability of recurrence following surgery (radical prostatectomy). The Han tables were designed to predict the probability of the first evidence of recurrence (detectable PSA level) after surgery.
Similar to the Partin tables, the Han tables correlate the three common factors known about a man’s prostate cancer, PSA level, Gleason score, and clinical stage (or pathological stage). While the Partin tables are used to predict pathological stage, the Han tables are used to predict the probability of prostate cancer recurrence up to 10 years following surgery. Based on the result of the probability of recurrence, men and their doctors can choose the best course of treatment.
Which model should I use?
1. Preoperative Model
- For men who are considering surgery for prostate cancer, but have not had surgery yet
- Prediction of recurrence probability following surgery using the available information BEFORE the surgery (PSA level, biopsy Gleason score, and clinical stage)
Based on PSA, gleason score, and clinical stage, recurrence probability is calculated at 3, 5, 7, and 10 years following surgery
Based upon PSA, surgical Gleason score and pathological stage, recurrence probability is calculated at 3, 5, 7, and 10 years following surgery
