Here, we linked national transplant and cancer databases to determine how lung cancer impacted prognosis in lung transplant recipients with incidentally explanted lung cancers (IELCs). Records from the Scientific Registry of Transplant Recipients and National Cancer Database were linked to identify 186 patients who received a lung transplant and were subsequently diagnosed with lung cancer. These patients were determined to have IELC and were compared to control patients who received a lung transplant but were not diagnosed with IELC. Of the 186 patients, 144 had non-small cell lung cancer (NSCLC), 6 had small cell lung cancer, and 36 had a neuroendocrine cancer. Patients with stage I/II NSCLC or any stage neuroendocrine cancer had comparable overall survival and rates of cancer-related mortality compared to controls. Conversely, patients with stage III/IV NSCLC had worse overall survival, higher rates of cancer-related mortality, and infrequently received cancer-specific non-operative treatment. Taken together, stage I/II NSCLC and neuroendocrine cancers should be reconsidered as an absolute contraindication to transplant. Conversely, patients with stage III/IV NSCLC had worse outcomes, and strategies are needed to increase the use of adjuvant therapy.</p>","PeriodicalId":123,"journal":{"name":"American Journal of Transplantation","volume":" ","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, more than 70% of lung transplant recipients receive induction with an IL-2 receptor antagonist, and basiliximab is the most used agent.

We assessed the feasibility of studying KT using the Epic Cosmos aggregated EHR dataset, which includes 274 million unique individuals cared for in 238 U.S. health systems, by comparing it with the Scientific Registry of Transplant Recipients (SRTR). We identified 69,418 KT recipients transplanted between January 2014 and December 2022 in Cosmos (39.4% of all US KT transplants during this period). Demographics and clinical characteristics of recipients captured in Cosmos were consistent with the overall SRTR cohort. Survival estimates were generally comparable, although there were some differences in long-term survival. At 7 years post-transplant, patient survival was 80.4% in Cosmos and 77.8% in SRTR. Multivariable Cox regression showed consistent associations between clinical factors and mortality in both cohorts, with minor discrepancies in the associations between death and both age and race. In summary, Cosmos provides a reliable platform for KT research, allowing EHR-level clinical granularity not available with either the transplant registry or healthcare claims. Consequently, Cosmos will enable novel analyses to improve our understanding of KT management on a national scale.</p>","PeriodicalId":123,"journal":{"name":"American Journal of Transplantation","volume":" ","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142643475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
