Patient selection: renal cell carcinoma, undergoing surgical resection
Parameters:
(1) serum CRP in mg/L (C)
(2) serum albumin in g/dL (A)
(3) absolute neutrophil count per microliter (N)
(4) absolute lymphocyte count per microliter (L)
(5) platelet count per microliter (P)
(6) hemoglobin in g/dL (H)
(7) gender
CRP to albumin ratio =
= (CRP) / (albumin)
neutrophil to lymphocyte ratio =
= ANC / ALC
platelet to hemoglobin ratio =
= ((platelet count) / 10000) / (hemoglobin)
