From: CYFRA21-1 is a more sensitive biomarker to assess the severity of pulmonary alveolar proteinosis
Serum biomarkers during different grade PAP patients. A Grade I, 20; grade II, 37; grade III, 40; grade IV, 38; grade V, 16. P value: all P > 0.05(serum LDH, CEA and CYFRA21-1 between Grand I and control group); all P > 0.05(serum LDH and CEA between Grand II and I or III), P = 0.003 (serum CYFRA21-1 between Grand I and II), and P = 0.031(serum CYFRA21-1 between Grand II and III); all P > 0.05(serum LDH, CEA and CYFRA21-1 between Grand IV and V); All the other P < 0.05 (serum LDH, CEA and CYFRA21-1 between other any two groups)
