To evaluate whether histologic subtype (nonspecific interstitial pneumonia versus usual interstitial pneumonia) in cryptogenic fibrosing alveolitis correlates with clinical, radiologic, and survival outcomes.
Reviewed 113 consecutive lung biopsies for diffuse lung disease and reclassified them using the Katzenstein and Myers criteria, identifying 15 patients with nonspecific interstitial pneumonia (NSIP) and 15 with usual interstitial pneumonia (UIP) after applying exclusion criteria.
Compared baseline clinical and computed tomography features, longitudinal lung function data, and survival status up to November 1998 between the two groups.
Overall survival was significantly greater in the NSIP cohort compared to the UIP cohort (p < 0.001), a difference not explained by treatment variations.
CT scans revealed significantly more fibrosis in UIP patients than in NSIP patients (p < 0.011), with UIP patients displaying progressive lung function deterioration while NSIP patients remained stable.
