CRP and IL-6 also correlated to cytokine intensity in gastric cancer [65] and certain clinical characteristics such as more advanced tumor stage in gastric [65, 79, 123] and colorectal cancer [92], shorter survival in colorectal [24, 94, 95], PC [135] and lung cancer [47], and cachexia in patients with colorectal [94], pancreatic [24, 82] and lung cancer [113].
