Abstract
BACKGROUND: With an increasing number of potential recipients and a comparatively static number of donors, lung transplantation (LT) in the elderly has come under significant scrutiny. Previous studies have been limited by single-center experiences with small population sizes and often mixed results. Using a national registry, we sought to evaluate the following: (1) differences in survival outcomes in septuagenarians compared with sexagenarians; and (2) the effect of temporal trends on the development of other comorbidities in this population. METHODS: We analyzed the Scientific Registry of Transplant Recipients (SRTR) data files from the United Network for Organ Sharing (UNOS) database to identify recipients who underwent LT between the years 2000 and 2013. The study period was divided into two equal eras. Using Kaplan-Meier analysis, we compared the 30-day, 3-month, 1-year, 3-year and 5-year patient survival between septuagenarians and sexagenarians in both eras. Separate multivariate analyses were performed to estimate the risk of renal failure, risk of rejection and length of hospital stay (LOS) post-LT in each of these time periods. RESULTS: A total of 6,596 patients were identified comprising 1,726 (26.2%) during 2000 to 2005 and 4,870 (73.8%) during 2006 to 2012. In the "early era," 32 (1.9%) septuagenarians and 1,694 (98.1%) sexagenarians underwent LT, whereas 543 (11.1%) septuagenarians and 4,327 (88.9%) sexagenarians underwent transplantation in the "latter era." A comparison of patient survival between the two groups in the early era revealed no difference at 30 days (95.7% vs 93.8%, p = 0.65). However, 3-month (91.2% vs 75%, p = 0.04) and 1-year patient survival (79.5% vs 62.5%, p = 0.048) were both lower in the septuagenarian group. In the later era, however, there were no differences in 30-day (96.2% vs 96.8, p = 0.5), 3-month (92.7% vs 91.9%, p = 0.56) or 1-year (81.7% vs 78.6%, p = 0.12) patient survival between the two age groups. Survival rates at 3 years (63.7% vs 49.3%, p < 0.001) and 5 years (47.5% vs 28.2%, p < 0.001) were each significantly lower in the septuagenarian group. CONCLUSION: Overall, LT outcomes for the elderly have improved significantly over time and early outcomes in the modern era rival those found in younger recipients.
