IL33 and non-small cell lung carcinoma: Among the four groups of patients with NSCLC, sarcoidosis (BBS), hypersensitivity pneumonitis (HO) and healthy controls that were studied, serum levels of IL-27, IL-31, and IL-33 did not differ, while BALF IL-33 levels did not change before or after chemotherapy [89] and therefore, were not predictive for lung cancer.
