Moreover, the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), the Prognostic Index (combination of C-reactive protein and white cell count) and Onodera’s Prognostic Nutritional Index have also been shown to be associated with cancer specific survival in patients with various cancers, including PDAC [8,9,10]. The gene discussed is CRP; the disease is cancer.
