Huang et al developed a simple prognostic model for patients with extranodal natural killer/T-cell lymphoma (ENKL). This tumor is common in Asia. The authors are from Sun Yat-Sen University in Guangdong, People’s Republic of China.
Patient selection: ENKL
Parameters:
(1) B symptoms
(2) Stage at presentation
(3) absolute lymphocyte count

prognostic score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 3
• The higher the score the worse the prognosis.
