Patients and Methods: We performed a retrospective study of the overall survival (OS) between advanced lung cancer patients with IIPs (n=28) and those without IIPs (n=145). Results: The OS in NSCLC patients with IIPs was shorter than in those without IIPs (median OS, 10.6 vs. 27.9 months, p=0.008) but the OS in SCLC patients with IIPs was not inferior to that of those without IIPs (12.7 vs. 14.8 months, p=0.835). Multivariate analysis showed that the small number of regimens increased the risk of mortality, instead of pre-existing IIPs. Conclusion: The continuation of chemotherapy in SCLC patients with IIPs made it possible to have a similar prognosis to that in those without IIPs.}, issn = {0250-7005}, URL = {https://ar.iiarjournals.org/content/35/2/1065}, eprint = {https://ar.iiarjournals.org/content/35/2/1065.full.pdf}, journal = {Anticancer Research} }
