Gastric adenocarcinoma: 1-year overall survival, disability-adjusted life years, years of life lost, and prognostic factors-a single-institution experience

To analyze factors affecting 1-year overall survival and burden of gastric adenocarcinoma in a single-institution cohort. A prospective cohort study of gastric adenocarcinoma patients from a cancer center in São Paulo, Brazil, was conducted between February 2016 and July 2019. Overall survival was a...

description To analyze factors affecting 1-year overall survival and burden of gastric adenocarcinoma in a single-institution cohort. A prospective cohort study of gastric adenocarcinoma patients from a cancer center in São Paulo, Brazil, was conducted between February 2016 and July 2019. Overall survival was analyzed at 12 months post-diagnosis using the Kaplan-Meier method. A log-rank test was applied to compare curves. Sociodemographic and clinicopathological features were assessed to detect prognostic factors using univariate and multivariable Cox regression analyses to calculate hazard ratio (HR) and its confidence intervals (CIs). Disability-adjusted life years (DALY) constituted the sum of years of life lost (YLL) plus years lived with disability (YLD). YLL represented the sum of years lost before the age of 76.6 years. YLD was calculated as the number of cases multiplied by the duration and burden of the disease. YLL per death was calculated as the mean YLL for each individual. Overall survival at 1-year follow-up was 80.8%. The multivariable model adjusted for age and sex identified cerebrovascular disease (HR 8.5, 95% CI 3.3-21.8), stage III/IV (HR 5.7, 95% CI 2.3-13.7), diabetes (HR 3.2, 95% CI 1.5-6.6), and

Out of the 214 treated cases, there was 700.72 DALY during the first year, of which 90.55% corresponded to YLL and 9.45% to YLD. The average YLL per death was 15.48 and was higher among women (19.24 YLL per death). At a single cancer center, 1-year overall survival probability was approximately 80% in patients with gastric adenocarcinoma. Patients with a higher risk of death had cerebrovascular disease, advanced clinical staging, diabetes, and/or lower educational level. Approximately 700 years of DALY was documented, with women having the highest YLL per death. Because this study was conducted at a single cancer center, the results might not be representative of a general population. To the best of our knowledge, this study was the first to assess gastric adenocarcinoma DALY, YLL, and YLL per death in the first year of follow-up in a hospital cohort in Brazil.</description><identifier>ISSN: 2234-943X</identifier><identifier>EISSN: 2234-943X</identifier><identifier>DOI: 10.3389/fonc.2022.918833</identifier><identifier>PMID: 36158672</identifier><language>eng</language><publisher>Switzerland: Frontiers Media S.A</publisher><subject>gastric adenocarcinoma ; Oncology ; prognostic factor ; survival ; years of life lived with disability ; years of life lost</subject><ispartof>Frontiers in oncology, 2022-09, Vol.12, p.918833</ispartof><rights>Copyright © 2022 Tiengo, Fernandes and Curado.</rights><rights>Copyright © 2022 Tiengo, Fernandes and Curado 2022 Tiengo, Fernandes and Curado</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c345t-ae4ddda72f6afeb67698993f28c26ec109d21c58eebc8eb0c68a25572a7e6b073</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC9493081/pdf/$$EPDF$$P50$$Gpubmedcentral$$Hfree_for_read</linktopdf><linktohtml>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC9493081/$$EHTML$$P50$$Gpubmedcentral$$Hfree_for_read</linktohtml><link.rule.ids>230,314,727,780,784,885,27924,27925,53791,53793</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/36158672$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Tiengo, Tatiane</creatorcontrib><creatorcontrib>Fernandes, Gisele Aparecida</creatorcontrib><creatorcontrib>Curado, Maria Paula</creatorcontrib><title>Gastric adenocarcinoma: 1-year overall survival, disability-adjusted life years, years of life lost, and prognostic factors-a single-institution experience</title><title>Frontiers in oncology</title><addtitle>Front Oncol</addtitle><description>To analyze factors affecting 1-year overall survival and burden of gastric adenocarcinoma in a single-institution cohort.
