The 5 Factors to sum: 

(1) pre-malignant-biopsy PSA (chose one): 

• 2.0-6.0 = 0 CAPRA points
  
• 6.1-10.0 = 1 CAPRA point
  
• 10.1-20.0 = 2 CAPRA points
  
• 20.1-30.0 = 3 CAPRA points
  
• higher than 30 = 4 CAPRA points

(2) highest Gleason score in biopsies (chose one):

• (1-3) plus (1-3)= ?...gives 0 CAPRA points
  
• (1-3) plus (4-5)= ?...gives 1 CAPRA point
• (4-5) plus (1-5)= ?...gives 3 CAPRA points
   

(3) [assumed?] actual clinical T stage (chose one):

• T1c to clinical T2...gives 0 CAPRA points
  
• clinical T3a... gives 1 CAPRA point
   

(4) percentage of cores that were cancerous cores (PPB%):

• less than 34%...gives 0 CAPRA points
  
• 34% or higher... gives 1 CAPRA point
   

(5) patient's age:

• younger than 50 years old...gives 0 CAPRA points
  
• 50 years old or more... gives 1 CAPRA point
