Study objective Cytokeratin 19 fragment (CYFRA) is a specific tumor marker in patients with
lung cancer; however, it has been reported that serum CYFRA levels are elevated in some
patients with nonmalignant respiratory diseases such as interstitial pulmonary fibrosis (IPF)
and collagen disease-associated pulmonary fibrosis (CDPF). To investigate the serum
CYFRA levels in nonmalignant respiratory diseases in detail, we studied 413 patients with
respiratory diseases. Design Retrospective study. Setting University hospital. Patients Four …
