However, there is no clear understanding of the specific link between interstitial lung abnormality (ILA) and CIP in patients with small\u2010cell lung cancer (SCLC). In addition, the prognosis of SCLC patients with ILA who receive chemoimmunotherapy is uncertain. Our study aimed to investigate the effect of ILA on the occurrence of CIP in SCLC patients receiving first\u2010line chemoimmunotherapy and to assess its relationship with prognosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a retrospective analysis of SCLC patients who received chemoimmunotherapy as a first\u2010line treatment between January 2018 and April 2024.

We investigated independent risk factors for CIP using logistic regression analysis and factors affecting PFS and OS using Cox regression analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 128 patients with SCLC were included in the study.
