Overview
Extranodal NK/T cell lymphoma survival rate is not well predicted by Ann Arbor staging system. A new system was introduced based on B symptoms, Ann Arbor system, LDH level, and regional lymphadenopathy combined. Another parallel mechanism for extranodal NK/T cell lymphoma is based on tumor biologic and micro-environmental factors. High Ki-67 nuclear antigen is a marker for actively proliferation tumor cell which could be a related factor with mass bulk.
Staging
- Extranodal NK/T cell lymphoma survival rate is not well predicted by Ann Arbor staging system. A new system was introduced by a Korean study based on B symptoms, Ann Arbor system, LDH level, and regional lymphadenopathy combined.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 |
- Another parallel mechanism for extranodal NK/T cell lymphoma is based on tumor biologic and micro-environmental factors. High Ki-67 nuclear antigen is a marker for actively proliferation tumor cell which could be a related factor with mass bulk.
