Montalban et al reported a prognostic index for patients with splenic marginal zone lymphoma. The acronym is HPLL for its parameters. The authors are from multiple institutions in Spain and Italy.
Patient selection: splenic marginal zone lymphoma
NOTE: The author subsequently reported a prognostic score using the same parameters.
Parameters:
(1) hemoglobin in g/L (H)
(2) platelet count in 10^9/L (P)
(3) serum LDH in U/L relative to upper limit of normal (L)
(4) extrahilar lymphadenopathy (L)
