Biopsy Gleason Scores Summarized by 4Kscore Test Risk

Gleason Score	Negative	6	3+4	4+3	8	9	Total
Low risk < 7.5%	11	2	2	0	0	0	15
Intermediate risk 7.5% – 19.9%	26	14	5	4	1	2	52
High risk ≥ 20%	35	24	22	11	7	5	104
Total	72	40	29	15	8	7	171

Two patients who had taken biopsy were excluded from this table because their biopsy results were not available. Higher 4Kscore Test result is associated with significantly higher risk of Gleason 7 or above at biopsy (P 5 0.009 by Fisher’s exact test).
