From: Interleukin-22 is elevated in lavage from patients with lung cancer and other pulmonary diseases
IL-22 concentrations in lavage are higher in patients with lung cancer. a Comparison between BL IL-22 concentrations found in n = 173 bronchoscopic lavage (BL) samples from patients with lung disease and controls (n = 22). b Comparison between BL IL-22 concentrations for samples from patients with pneumonia (n = 47) and controls (n = 22). c Comparison between BL IL-22 concentrations of patients with lung cancer (n = 20) and controls (n = 22). Samples from lung cancer patients with a known coexisting inflammatory lung pathology such as COPD or lung infection were excluded from this analysis to avoid confounding due to additional inflammation. d Comparison between BL IL-22 concentrations for samples from patients with lung cancer and thoracic manifestations of other malignancies, summed up as “cancer” (n = 34) and controls (n = 22). P-values were calculated using the two-part Wilcoxon test after setting all values <15 to 0
