Fig. 4From: CYFRA21-1 is a more sensitive biomarker to assess the severity of pulmonary alveolar proteinosisSerum biomarkers in APAP patients between before treatment and after six months. Serum CYFRA21-1 of patients with PAP after six months were higher than baseline in aggravated group (P = 0.003). Serum LDH, CEA and CYFRA21-1 of patients with PAP after six months were lower than baseline in relieved group (P = 0.005, 0.005; P < 0.001)Back to article page
