Tanigluchi et al reported the hemoglobin-platelet index (HPI) for evaluating a patient with diffuse large B-cell lymphoma (DLBCL). The authors are from Kindai University and Perfect Liberty General Hospital in Osaka, Japan.
Patient selection: diffuse large B-cell lymphoma (DLBCL)
Parameters:
(1) hemoglobin in g/L and sex (as a measure of anemia)
(2) platelet count in 10^9/L (as a measure of thrombocytopenia)
