International Prognostic Scoring System
The International Prognostic Scoring System (IPSS) is used by many doctors to help assess the severity of a patient's myelodysplastic syndrome (MDS). Based on the IPSS score, the patient's history, and his/her personal observations, the physician will design a treatment plan to address the MDS.
The IPSS uses three "prognostic indicators" to develop a "score" which may be useful in understanding how the MDS may progress:
Each indicator is rated according to its severity and the ratings are combined into a "score."
Scores are sorted into one of four risk categories:
The two lower categories can be further described as the lower risk group while the two upper categories can be further described as the higher risk group.
