This work aimed to identify the immune-related gene signature that can predict the prognosis of NSCLC patients receiving ICI treatment.\nMethods: The ImmPort database was queried to obtain a list of immune-related genes (IRGs). Differentially expressed IRGs in NSCLC patients were identified using the TCGA database. RNA-seq data and clinical information from NSCLC patients receiving immunotherapy were obtained from the GEO database (GSE93157 and ////). A gene signature was generated through multivariate Cox and LASSO regression analyses. The prognostic value and function of this gene signature were thoroughly investigated using comprehensive bioinformatics analyses.\nResults: A total of 6 prognostic-related genes were identified from 617 differentially expressed genes, and two prognostic-related differentially expressed genes (CAMP and IL17A) were determined to construct gene signature. Our gene signature demonstrated superior performance compared to other clinicopathological parameters in predicting the prognosis of NSCLC patients receiving immunotherapy, with an area under the ROC curve (AUC) of 0.812. Furthermore, immune infiltration analysis indicated that the high-risk group was enriched with resting CD4 T cell memory, while the low-risk group showed a \"hot\" tumor microenvironment that promotes anti-tumor immunity in NSCLC patients.\nConclusion: Gene signatures based on immune-related genes exhibited excellent indicator performance of prognosis and immune infiltration, which has the potential to be an effective biomarker for NSCLC with ICI treatment.", "claims": [{"id": "claim-method", "statement": "A gene signature was generated through multivariate Cox and LASSO regression analyses.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:38463866", "locator": "sections[0] \"Abstract\" paragraph 2", "quote": "A gene signature was generated through multivariate Cox and LASSO regression analyses."}], "state": "complete"}, {"id": "claim-data-access", "statement": "All data included in this study are available including GEO database (GSE93157 and GSE135222), TCGA database, and cBioPortal for cancer genomics database.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:38463866", "locator": "sections[24] \"Data availability\" paragraph 2", "quote": "All data included in this study are available including GEO database (GSE93157 and GSE135222), TCGA database, and cBioPortal for cancer genomics database."}], "state": "complete"}, {"id": "claim-target-result", "statement": "Our gene signature demonstrated superior performance compared to other clinicopathological parameters in predicting the prognosis of NSCLC patients receiving immunotherapy, with an area under the ROC curve (AUC) of 0.812.", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:38463866", "locator": "sections[0] \"Abstract\" paragraph 3", "quote": "Our gene signature demonstrated superior performance compared to other clinicopathological parameters in predicting the prognosis of NSCLC patients receiving immunotherapy, with an area under the ROC curve (AUC) of 0.812."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "complete", "objective": "Our gene signature demonstrated superior performance compared to other clinicopathological parameters in predicting the prognosis of NSCLC patients receiving immunotherapy, with an area under the ROC curve (AUC) of 0.812.", "steps": [{"id": "read_published_estimate", "order": 1, "name": "Read the published estimate from the source", "kind": "other", "state": "complete", "blocked_on": null, "description": "The claim, method and evidence span published with the source article.", "duration_hours": null, "parameters": {}, "inputs": ["source:pmid:38463866"], "outputs": ["the published estimate and its evidence"], "instruments": [], "reagents": []}, {"id": "obtain_source_data", "order": 2, "name": "Obtain the source data from the named repository", "kind": "data-preparation", "state": "complete", "blocked_on": null, "description": "The GEO series accession resolves and its sample accessions are listed.
