Overview
Staging
Extranodal NK/T cell lymphoma survival rate is not well predicted by Ann Arbor staging system.[1] A new system was introduced by a Korean study based on B symptoms, Ann Arbor system, LDH level, and regional lymphadenopathy combined.[2]Four risk groups identified as below:
- group 1: No adverse factor
- group 2: One factor
- group 3: Two factors
- group 4: Three or more factors
| Group | Altered factors count | 5 year prognosis |
|---|---|---|
| 1 | N.O. | 81000 out of 100000 |
| 2 | 1 | 64000 out of 100000 |
| 3 | 2 | 34000 out of 100000 |
| 4 | 3/More | 7000 out of 100000 |
