Patients with NSCLC and treated with PD-1/PD-L1 immune checkpoint inhibitors between Jan 2010 and Dec 2020 were included. Overall survival (OS) was estimated using the Kaplan-Meier method and compared using Cox proportional hazards regression. Hospitalizations and duration of treatment were compared secondarily using logistic and linear regression. A total of 4306 patients received ICI and 54% of patients had a diagnosis of COPD. Median (95% CI) OS was 9.2 (8.5-9.9) months for patients with COPD and 8.2 (7.3-8.8) for patients without COPD, which was not significantly different (adjusted hazard ratio (aHR) = 0.94, 95% CI, 0.87-1.01, P = 0.092). Similarly, the median time on treatment was not different (85 vs. 99 days, multivariable P = 0.10).

Multi-omics data were stratified using the MOVICS package, identifying different molecular subtypes. Our analysis identified 2 molecular subtypes (CS1 and CS2) with significant survival differences. Transcriptional regulatory network analysis revealed differential activation of transcription factors such as FOXA1 and GATA3 in CS1, whereas AR and ESR2 were enriched in CS2. A robust prognostic signature comprising 5 key genes was developed through the integration of 10 machine learning algorithms, demonstrating high predictive power across data sets. Immune cell infiltration analysis revealed that anti-tumor immune cells were more abundant in low-risk groups, whereas pro-tumor immune cells predominated in high-risk groups. Furthermore, low-risk patients exhibited better immunotherapy responses and higher tumor mutational burden (TMB).

The immune checkpoint receptor programmed cell death-1 (PD-1) can bind to its ligand programmed cell death-ligand 1 (PD-L1), which is expressed on the surface of cancer cells. This interaction suppresses T-cell activation and promotes immune tolerance. Radiation therapy can increase the expression of PD-L1 on tumor cells, which can lead to a decrease in the effectiveness of the treatment, and detailed studies are needed to understand the mechanisms. As many patients develop resistance to chemotherapy and radiotherapy-either through lack of response or cancer recurrence-there is a critical need to maximize synergistic effects by selecting combination treatments that offer improved therapeutic efficacy with minimal side effects. In the present study, immature DCs (iDCs) were introduced directly into irradiated tumor sites (referred as IR/iDCs), and immune checkpoint blockades (ICBs) were administered intraperitoneally. We confirmed the antitumor effect of combining IR/iDCs and ICBs by examining tumor growth and mouse survival. The proportion of CD4 + and CD8 + T cells in splenocytes increased in the IR/iDCs-treated groups. Combining IR/iDCs with an anti-PD-L1 antibody led to a significant reduction in distant tumor growth and improved mouse survival rates compared with IR/iDCs alone or IR/iDCs + anti-PD-1 antibody. These findings suggest that integrating radiotherapy, DC-based immunotherapy, and ICB, specifically targeting PD-L1, may be an effective cancer treatment strategy.</p>","PeriodicalId":15996,"journal":{"name":"Journal of Immunotherapy","volume":" ","pages":"89-96"},"PeriodicalIF":3.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11875407/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142895032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
