Extranodal NK/T-cell lymphoma (ENKL) is a rare subtype of NHL (Non-Hodgkin lymphoma]. It occurs mostly in the nasal and paranal areas. Most of the cases are presented stage I/II. International prognostic index (IPI) can predict the outcome. However, better prognostic model is available such as NKIPI. Because of high expression of p-glycoprotein, ENKL is refractory to chemotherapy. Early stage disease can be bestly treated with concurrent chemoradiation. For advanced stage disease, new clinical trials are now being conducted. |
