PINK (Prognostic Index for Natural Killer/T-cell lymphoma)
Stratifies newly diagnosed extranodal NK/T-cell lymphoma into three prognostic groups from four baseline factors to guide risk-adapted therapy in the non-anthracycline era; this is the four-factor PINK, NOT PINK-E (which adds EBV DNA), and it is a prognostic index for an already-diagnosed lymphoma, not a diagnostic, screening, or staging test.
