IL6 and Anorexia: Correlation analysis of the post-/pretreatment ratios of serum TNF-α, TGF-β, and IL-6 levels with fatigue or anorexia over 2–10 weeks (Table 2) revealed that the post-/pretreatment ratio of serum TGF-β levels at 10 weeks in patients with fatigue (median = 0.94; interquartile range; IQR = 0.78–1.04) was significantly higher (p = 0.020) than that in patients without fatigue (median = 0.68; IQR = 0.55–0.81).
