Based on a review of the literature, eight parameters were evaluated as potential prognostic markers of survival outcomes: the blood-based parameters C-reactive protein (CRP), neutrophil–lymphocyte ratio (NLR), lymphocyte–monocyte ratio (LMR), platelet–lymphocyte ratio (PLR) and anemia (hemoglobin—HB) and the clinical factors age, ECOG performance status and the extent of disease (local disease only vs metastatic disease). Here, CRP is linked to anemia.
