OPTN/SRTR 2020 Annual Data Report: Lung
Abstract
For the first time in a decade, both the number of candidates added to the waiting list and the number of lung transplants performed decreased from the year prior; the number of lung donors also declined. This slowing of transplant activities in 2020 was associated with a modest increase in waitlist mortality. The year 2020 was notable for the global outbreak of the COVID-19 pandemic, which undoubtedly influenced all trends noted in lung transplantation. Time to transplant continued to decrease, with a median time to transplant of 1.4 months across all waitlist candidates. Posttransplant survival remained stable, with 89.4% of transplant recipients surviving to 1 year, 74.8% to 3 years, and 61.2% to 5 years.
Introduction
The year 2020 was remarkable for lung transplantation in many ways. The COVID-19 pandemic was declared in 2020, affecting every aspect of society worldwide, including the US transplant system. COVID-19-related restrictions and the health risks the virus posed to transplant candidates and recipients resulted in changes in center listing and transplant practices, and in time a COVID-19-related indication for lung transplant emerged. Compared with 2019, transplant activity declined. Fewer candidates were added to the lung transplant waiting list in 2020, with 2696 new candidates (Figure LU 1) and 2597 lung transplants performed (Figure LU 50).
In 2020, the impact of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapy on cystic fibrosis patients came into focus, with potential transplant candidates experiencing stabilization and even improvement in their lung function, and so followed a precipitous decline in number of cystic fibrosis patients requiring a transplant. A lower proportion of candidates with cystic fibrosis was on the lung transplant waiting list, waitlist mortality rates decreased and, ultimately, fewer cystic fibrosis patients underwent lung transplant. Because long-term trends have yet to be observed, it is not known if these changes will persist or what we are witnessing is simply a delay in the need for transplant. Notably, some trends seen in the 2020 data may be impacted by changes in center listing or transplant practices amid the COVID-19 pandemic.
Last, work began to change the US lung transplant allocation system to the continuous distribution framework, in which the bounds of geography will become more flexible in relation to clinical factors that impact waitlist and posttransplant survival. Currently, candidates 12 years or older access lung transplant based on their calculated lung allocation score (LAS), age, geography, blood type compatibility and, if necessary, waiting time. Candidates younger than 12 years access transplant based on illness-based priority status, age, geography, blood type compatibility, and waiting time. The LAS calculates transplant benefit by estimating waitlist and posttransplant mortality. Currently, waitlist survival accounts for two-thirds and posttransplant survival accounts for one-third of the LAS, reflecting the preference for prioritizing waitlist mortality over posttransplant survival. Pulmonary diseases are categorized into four main diagnosis groups: group A, obstructive lung disease; group B, pulmonary vascular disease; group C, cystic fibrosis and immunodeficiency disorders; and group D, restrictive lung diseases. These groupings represent similar survival probability and disease pathophysiology. Notable changes to the LAS system that may impact interpretation of the data presented in this report include: (1) the 2015 update with a more contemporary cohort and addition of new variables to characterize disease severity for candidates in diagnosis group B; and (2) the 2017 replacement of donation service area with 250 nautical-mile radius from the donor hospital as the first unit of allocation, as a first step toward addressing geographic disparities in access to transplant.
In this report, all lung transplant candidates and recipients 18 years or older are included under Adult Lung Transplant, and those <18 years are included under Pediatric Lung Transplant. Heart-lung candidates and recipients are included in all tabulations. The data presented cover January 1 to December 31, 2020, except for the COVID-19 data, in which the latest available data is presented to July 31, 2021. The data presented here generally cover January 1, 2009, to December 31, 2020, with the addition of a few COVID-19 data points through July 31, 2021.
Adult Lung Transplantation in the US
Impact of COVID-19
The US declared a national emergency due to the COVID-19 pandemic on March 13, 2020; however, COVID-19 diagnosis codes were added to the Organ Procurement and Transplantation Network (OPTN) system on October 28, 2020, providing at least a 7-month lag in the collection of standardized data for this diagnosis. Transplant centers had the option to retrospectively change diagnoses for candidates with COVID-19 for this period once the diagnosis codes became available. In 2020, 21 candidates were listed for transplant with a COVID-19 diagnosis; of those, 17 (81%) underwent transplant, 2 (9.5%) died waiting, 1 (4.8%) died during the transplant procedure, and 1 (4.8%) was removed due to deteriorating health. An additional 5 patients received a transplant for this diagnosis who were not recorded to have COVID-19 at listing because diagnoses can be updated between listing and transplant, resulting in a total count of 22 lung transplant recipients in 2020.
From January 1 to July 31, 2021, 197 candidates with a COVID-19 diagnosis were added to the waiting list. Of these, 165 (84%) underwent transplant, 7 (3.6%) died waiting, 6 (3.1%) were removed for improved condition, 9 (4.6%) deteriorated, 1 was removed for other reasons, and 9 (4.6%) remain on the list. For the same reasons cited above, an additional 3 patients were reported with a COVID-19 diagnosis at transplant, resulting in a total of 168 lung transplant recipients in the first 7 months of 2021. In 2021, six transplant recipients died shortly posttransplant (three died within two weeks, two within 2 months posttransplant, and two within 6 months). The follow-up period for COVID-19 transplant recipients in 2021 is short and incomplete; however, it is being reported due to the novelty of this diagnosis and the transplant community’s interest in this population.
Waiting List
Characteristics of adult candidates listed for lung transplant
In 2020, 2696 new candidates were added to the lung transplant waiting list (Figure LU 1), a 17% decline from 2019. Adults aged 50-64 comprised 47% of the US lung transplant waiting list, although the percentage of candidates 65 years or older continued to increase, while the percentage of individuals 49 years or younger decreased (Figure LU 3). Since 2011, the proportion of candidates on the waiting list 65 years or older has nearly doubled, from 18.6% to 33.0% in 2020. There continues to be a higher percentage of men than women waiting for a lung transplant (Figure LU 4). The proportion of non-White candidates continues to increase, with Black, Asian, Hispanic, and “other” races comprising 28.2% of the waiting list (Figure LU 5). Lung transplant candidates in diagnosis group D continue to increase and represented 60.2% of the lung transplant waiting list. Diagnosis group A candidates decreased to 26.5% of the waiting list, and diagnosis group C candidates decreased from 7.4% in 2019 to 4.1% of candidates in 2020 (Figure LU 6). About one-third of candidates fall into the lowest LAS category, <35, 28.0% have LAS 35-<40, 21.6% have LAS 40-<50, and 6.2% have LAS 50-<60 (Figure LU 8). Candidates in the highest LAS category, 60 and above, continue to comprise 12.3% of the waitlist population. Most adults awaiting transplant are 150 to 180 cm (5 foot 2 to 5 foot 11 inches) tall, while 3.0% are under 150 cm, and 15.0% are over 180 cm (Figure LU 9). The proportion of candidates by blood type are like the general population, with type O blood comprising 50% of the waiting list, type A comprising 35.8%, type B comprising 11.1%, and type AB comprising 3.1%, respectively (Figure LU 10). The percentage of candidates with a prior lung transplant is 3.6%, a trend that has remained stable over time (Figure LU 11).
Outcome of adult candidates listed for lung transplant
Seventy-six percent of lung transplant candidates in 2020 were on the waiting list fewer than 90 days (Figure LU 7). Deceased donor lung transplant rates were the highest ever in 2020 at 218.6 transplants per 100 waitlist years (Figure LU 12). At the same time, waitlist mortality increased slightly from 14.7 deaths per 100 waitlist years in 2019 to 16.1 in 2020 (Figure LU 25). Transplant rates increased markedly for candidates 65 years or older, from 238.9 transplants per 100 waitlist years in 2019 to 302.1 in 2020 (Figure LU 13); candidates 50 to 64 years also experienced an increase in transplant rates from 172.4 to 209.1 transplants per 100 waitlist years. This mirrored an increase in transplant rates for candidates in diagnosis group D, which increased from 263.0 transplants per 100 waitlist years in 2019 to 308.7 in 2020 (Figure LU 15). Transplant rates declined sharply for diagnosis group C candidates, from 201.9 transplants per 100 waitlist years in 2019 to 92.7 in 2020 (Figure LU 15). Overall median waiting time for candidates in the US was 42 days in 2020, with the shortest waiting time for diagnosis group D candidates at 36 days, followed by diagnosis group C at 55 days, diagnosis group A at 68 days, and diagnosis group B at 78 days (Figure LU 20). As expected, median waiting time was inversely related to LAS, with those in the highest LAS range of 50-100 experiencing the shortest median waiting time of 17 days and those in the lowest LAS range of less than 35 with the longest median waiting time of 80 days (Figure LU 21). Transplant rates were highest for White candidates, followed by “other,” Asian, Hispanic, and Black candidates (Figure LU 14). Candidates with blood type AB experienced the highest transplant rates, followed by type A, B, and O, respectively (Figure LU 16). Candidates taller than 180 cm experienced the highest transplant rates, with declining rates as candidate height decreased (Figure LU 17). There was geographic variability in the percent of candidates who were transplanted within a year, by the state where the candidate lived, from 50%-100% (Figure LU 24). Differences were likely influenced by both the number of candidates per state and the number of transplant centers within a state (Figure LU 24). Transplant rates did not differ between residents of metropolitan or non-metropolitan areas (Figure LU 18).
While pretransplant mortality increased slightly over the last year, it has been declining since 2014, when 22.1 deaths per 100 waitlist years occurred, compared with 16.1 in 2020 (Figure LU 25). Candidates 65 years and older experienced the greatest pretransplant mortality rate of all age categories, a trend that remains largely unchanged over the past 5 years (Figure LU 26). Pretransplant mortality was greater for men, with 21.3 deaths per 100 waitlist years, compared with 12.6 for women, and varies annually by race, which may be influenced by small subgroups (Figure LU 28 and Figure LU 27, respectively). Pretransplant mortality varied by diagnosis group, with the highest mortality rate in group D, followed by group B, group A, and group C, respectively (Figure LU 29). Pretransplant mortality continued to decline for candidates with an LAS of 60 or above (Figure LU 30). Biological factors influenced access to transplant. Candidates <150 cm in height experienced the greatest pretransplant mortality, likely due to a smaller supply of appropriately sized donor organs (Figure LU 32). A clear trend for impact of blood type on access to transplant is not evident, likely because the lung allocation policy of prioritizing blood type identical over compatible donor-recipient matching allows blood type O candidates access to these universally compatible organs (Figure LU 31). Data about degree of immunological sensitization of candidates are not shown because the data are missing in a nonrandom fashion and may be misleading. Of candidates removed from the waiting list for reasons other than transplant or death, 18.8% died within 6 months of removal (Figure LU 35). Higher percentages of post-removal deaths occurred among those 65 years or older (Figure LU 37) and those in diagnosis group D (Figure LU 36).
Donors
There were 2578 deceased lung donors in 2020, compared with 2755 in 2019 (Figure LU 38); this unusually large decline in recovered donor lungs may be due to the impact of the COVID-19 pandemic on considerations such as determining donor eligibility and travel restrictions faced by organ procurement teams. Of the donors, 185 (7.2%) were younger than 18 years, 2125 (82.4%) 18-54 years, and 268 (10.4%) 55 years or older (Figure LU 39, Figure LU 40); 39.4% of donors were women (Figure LU 41), 19.0% Black, 18.0% Hispanic, and 3.4% Asian (Figure LU 42). In 2020, 5.4% lungs were recovered for transplant and not transplanted, with the highest proportion occurring in donors 55 years or older and those with a cause of death of anoxia (Figure LU 44, Figure LU 45, Figure LU 46). Utilization of increased risk donors continues to improve, with 95% of lungs recovered for transplant ultimately used for transplant (Figure LU 47). A minority of donors, 7.4%, had a smoking history of 20 pack-years or more (Figure LU 48). The most common causes of donor death were anoxia and head trauma (37% each), followed by cardiovascular accidents/stroke (Figure LU 49). In 2020, 7.4% of transplants used “donation after circulatory death” donors, which has increased from 3.1% in 2015 (Table LU 8).
Transplant
Characteristics of adult lung transplant recipients
In 2020, in line with a decreased number of donor lungs, 2597 lung transplants were performed, compared with 2759 the year prior, a 5.9% decline (Figure LU 50). Bilateral lung transplants accounted for 78% of procedures (Figure LU 51). There were 93 (3.6%) re-transplants and 53 (2.1%) heart-lung transplants performed (Table LU 8). By age, in decreasing order, the number of lung transplants performed were: 50-64 years, 1175; 65 years or older, 982; 35-49 years, 262; 18-34 years, 142; and younger than 18 years, 36 (Figure LU 52). Male recipients outnumbered women, at 1518 transplants (58%) versus 1100 (42%) (Figure LU 53). The number of transplants was greatest for diagnosis group D, at 1708, followed by group A (608), group B (205), and group C (76) (Figure LU 55). Notably, the number of transplants for group C decreased by 68.9% from 2019 to 2020. The overall median LAS at transplant was 40.7, and 543 transplants occurred in recipients with an LAS of >60, 216 with an LAS of 50-<60, 614 with an LAS of 40-<50, 605 with an LAS of 30-<40, and 605 with an LAS of <35 (Figure LU 57, Figure LU 56). Median LAS differed by diagnosis group, with the highest median LAS of 46.6 in group B, followed by 44.2 in group D, 43.8 in group C, and 33.7 in group A (Figure LU 58).
Sixty-eight centers performed lung transplants last year (Figure LU 90). The median number of transplants performed by centers was 34, with a 25th-75th percentile of 20-55 (Figure LU 62). Twenty percent of transplants were performed at centers with an annual transplant volume >100, 45.5% at centers performing 41-100 transplants, and 33.4% at centers performing 11-40 transplants, with less than 1% occurring at centers performing 10 or fewer transplants annually (Figure LU 63).
Outcomes of adult lung transplant recipients
Posttransplant survival trends remained stable, with 89.4% of recipients in 2019 surviving to one year, 61.2% in 2015 to five years, and 33.1% in 2010 to 10 years (Figure LU 64). Five-year posttransplant survival was lowest for recipients aged 65 and older, followed by those aged 18-34, 50-64, and 35-49, respectively (Figure LU 65). Five-year survival varied by race; by five years posttransplant, Black recipients had a survival of 54.5%, followed by White recipients (60.2%), Asian recipients (62.4%), and Hispanic recipients (64.1%) (Figure LU 66). By five years posttransplant, those with LAS values of =50 had the lowest survival, and those with LAS values of <40 had the highest survival (Figure LU 67). Recipients of bilateral transplants had better five-year survival (63.1%) than single-lung recipients (53.3%) (Figure LU 68). This is likely confounded by pretransplant characteristics informing decisions on procedure type. Diagnosis group C recipients had the best five-year survival (66.6%), followed by group A (62.4%), group B (59.5%), and group D (57.8%) (Figure LU 69).
Posttransplant outcomes, other than survival data reported above, has varying degrees of missingness particularly as time from transplant increases and should be interpreted with caution. Induction agents were used commonly at transplant; induction therapy was reported for 80.9% of recipients, and 81.5% reported the most common immunosuppression regimen of tacrolimus, mycophenolate mofetil, and prednisone (Figure LU 59, Figure LU 60). In the first posttransplant year, an episode of acute rejection was reported in 14.6% of lung transplant recipients, which varied slightly by age (12.5%-18.18%) (Figure LU 73). Episodes of acute rejection in the first year were most commonly reported in recipients with no induction therapy reported (19.6%), followed by those reporting T-cell-depleting agents (18.4%) and IL-2 receptor antagonists (13.0%) (Figure LU 74). Posttransplant lymphoproliferative disorder was most commonly reported among recipients who were Epstein-Barr virus-negative (7.6%) compared with 1.1% in those who were Epstein-Barr virus-positive (Figure LU 75). By 1 year, 5.7% of recipients had bronchiolitis obliterans syndrome (BOS) reported, and by year 5, 40.2% did. Creatinine of >2.5 mg/dl was reported in 4.8% of recipients by 1 year and 12.5% by 5 years, and 1.9% reported chronic dialysis by year 1 and 3.3% by year 5. Malignancy was reported in 24.0% of recipients by 5 years posttransplant. Most recipients (80%) had a functional status of no assistance needed at both 1 and 5 years posttransplant (Table LU 10).
Pediatric Lung Transplant in the US
Waiting List
Characteristics of pediatric candidates listed for lung transplant
In 2020, 58 new pediatric candidates (aged <18 years) were added to the lung transplant waiting list (Figure LU 76), and 88 candidates were on the list at some point during the year (Figure LU 77). The number of pediatric waitlist candidates decreased from 249 in 2010 to 88 in 2020 (Figure LU 77). The largest age-group of pediatric candidates on the waiting list in 2020 was 12-17 years (51.1%,) followed by 1-5 years (23.9%), younger than 1 year (15.9%), and 6-11 years (9.1%) (Figure LU 78). Most pediatric lung transplant candidates were White (62.5%), followed by Hispanic (19.3%), Black (9.1%), and Asian (3.4%) (Figure LU 79). Most (73.9%) pediatric candidates on the waiting list in 2020 had been on the list fewer than 90 days (Figure LU 81).
Outcomes of pediatric candidates listed for lung transplant
Of 66 candidates removed from the waiting list in 2020, 36 (54.6%) were removed after undergoing transplant, 8 (12.1%) after death, 8 (12.1%) due to improved condition, and 4 (6.0%) due to becoming too sick to undergo transplant (Table LU 14, Table LU 15). Among pediatric lung transplant candidates listed in 2017, 66.2% underwent deceased donor transplant within 3 years, 14.7% died waiting, 16.7% were removed from the list for reasons other than transplant or death, and 2.5% were still waiting (Figure LU 82). The overall pediatric lung transplant rate has generally increased since 2012, from 39.5 transplants per 100 waitlist-years to 131.3 in 2020 (Figure LU 83). Transplant rates varied with age and were highest for candidates aged 12-17 years (244.7 per 100 waitlist years), followed by candidates younger than 1 year (203.3 per 100 waitlist years), 6-11 years (111.6 per 100 waitlist years), and 1-5 years (26.3 per 100 waitlist-years) (Figure LU 84). Transplant rates also varied by race, with the highest rates among Black candidates (632 per 100 waitlist years), followed by Hispanic candidates (278.6 per 100 waitlist years) and White candidates (84.2 per 100 waitlist years) (Figure LU 85). Pretransplant mortality decreased from a peak of 42.9 deaths per 100 waitlist years in 2015 to 27.1 in 2020 (Figure LU 86). Pretransplant mortality varied by age, ranging from 24.2 deaths per 100 waitlist years among candidates aged 6-11 years to 58.1 among candidates younger than 1 year (Figure LU 87).
Transplant
Characteristics of pediatric lung transplant recipients
In 2020, 36 lung transplants were performed in pediatric recipients 0-17 years (Figure LU 88), seven in those younger than 1 year, three in those 1-5 years, four in those 6-11 years, and 22 in those 12-17 years (Figure LU 89). In 2020, 10 programs were characterized as providing pediatric transplant, compared with 61 programs that offered transplants for adults (Figure LU 90). Since 2008, cystic fibrosis remained the leading indication for pediatric lung transplant (Table LU 17). More than half of pediatric lung transplant recipients in 2018-2020 were not hospitalized at the time of transplant (Table LU 17). An increasing proportion of candidates were bridged to transplant; 7.0% required mechanical ventilation and extracorporeal membrane oxygenation (ECMO), 10.2% mechanical ventilation only, and 12.5% ECMO only (Table LU 17). Time to transplant has decreased over the past decade, with 46.9% of recipients in 2018-2020 with wait times shorter than 31 days, compared with 21.4% in 2008-2010 (Table LU 18). Induction therapy was reported in 86.1% of pediatric lung transplant recipients in 2020 (Figure LU 91). The most common initial immunosuppression regimen was tacrolimus, mycophenolate, and steroids, reported in 91.7% of pediatric lung recipients (Figure LU 92). Among pediatric lung transplant recipients in 2018-2020, the combination of a cytomegalovirus (CMV)-positive donor and CMV-negative recipient occurred in 35.2% of transplants; this combination for Epstein-Barr was used in 33.6% of transplants (Table LU 19).
Outcomes of pediatric lung transplant recipients
Across all pediatric recipients who underwent lung transplant in 2013-2015, 1-, 3-, and 5-year patient survival was 85.4%, 62.2%, and 53.7%, respectively (Figure LU 96). Incidence of death was 3.8% at 6 months and 7.7% at 1 year for transplants in 2019, 37.8% at 3 years for transplants in 2017, 47.7% at 5 years for transplants in 2015, and 59.6% at 10 years for transplants in 2010 (Figure LU 95). The incidence of post-transplant lymphoproliferative disorder among Epstein-Barr-negative recipients who underwent transplant in 2008-2018 was 9.9% at 5 years posttransplant, compared with 1.1% among Epstein-Barr-positive recipients (Figure LU 94). Complication rates in pediatric lung transplant recipients increased with time posttransplant, including bronchiolitis obliterans syndrome (1.9% at 1 year, 30.3% at 5 years) (Table LU 20). For most surviving pediatric lung transplant recipients (89.9%), functional status was reported as fully active at 5 years posttransplant.
