(Liver Transpl 2003;9:1231-1243.)

The European Liver Transplant Registry (ELTR)has cumulated data concerning 46,530 liver trans-

plantations (LTs) in 41,522 patients from 124 centersin 21 countries from May 1968 to December 2001(Fig. 1). These data give a comprehensive overview ofthe status and evolution of LT in Europe. Both numberof transplant centers and annual number of LTs per-formed in Europe have gradually increased since theELTR was created (Fig. 2). The following analysis wasundertaken using ELTR data from January 1988 toDecember 2001 (44,286 LTs, 39,196 patients). Janu-ary 1988 was chosen because it corresponds to the dif-

fusion of cyclosporine-based immunosuppression andstandardization of the surgical procedure.

Background of the ELTR

The ELTR is a Service of the European Liver Trans-plant Association, which is part of the European Societyfor Organ Transplantation. The ELTR represents morethan 95% of overall European data compared with pub-lished official figures.1 To encourage completion, anELTR Expert Committee decided intentionally to limitthe two-part questionnaire to the most relevant items.The first part of the questionnaire includes 34 items

regarding date and indication for LT, donor and recip-ient blood group compatibility, technical aspects of LT,and immediate postoperative immunosuppressiontherapy. The second part (11 items) concerns graft andpatient outcome and immunosuppressive regimen fol-low-up. Participation in the ELTR is voluntary, and astandard computerized database is provided to contrib-uting centers with a detailed instruction handbook forthe collection of accurate and uniform data. To avoidspelling and typing errors, all items are pull-downmenus, except for names of transplant recipients anddates. Centers send a copy of their database twice a year.Data then are subjected to checks for completeness andconsistency. Comprehensive logical intra-updates andinter-updates are performed routinely.

The ELTR has developed partnerships with themain European Organ Sharing Organisations: UKTransplant in the United Kingdom; Organizacion

Nacional de Transplantes in Spain; the EurotransplantFoundation, which includes Austria, Belgium, Ger-many, Luxemburg, Slovenia, and The Netherlands;and Scandiatransplant, which includes Denmark, Fin-land, Norway, and Sweden. These relationships repre-sent an additional way to control the quality of bothELTR and Organ Sharing Organisation data. Periodicmeetings and workshops are organized by the ELTRCommittee, ELTR Expert Committee, and contribu-tors to review the questionnaire and update the proce-dures of data collection and analysis. Twice a year, anELTR report is sent to participating centers, with asummary of results presented as tables and figures.Main data are available in the ELTR Web site (www.eltr.org) and have been published.2 In addition, theELTR database recently allowed the development of arisk model for LT mortality according to donor andrecipient characteristics and transplant procedure.3

This model can be used prospectively for an individualpatient profile and to perform risk-adjusted compari-sons of patient outcomes among centers.

To ensure the reliability of the scientific analysis ofall data, a control of adequacy between the ELTR ques-tionnaire and patient charts is performed by randomlyconduced audit visits. Seven hundred thirty-four filesfrom 21 centers were audited between June 1998 andJune 2001. The ELTR completeness rate was 95%, andthe consistency rate between charts and the ELTR was98%. Agreement between the ELTR and chart reviewwas very good for all conditions. No significant corre-lation was found between quality of data and experienceof visited centers. Results of audit visits indicate thatELTR data are reliable and scientific results of theELTR can be considered credible and representative ofLT in Europe.4

Results of LT in Europe

Main Indications for LT in Europe

Main indications for LT in Europe with the corre-sponding survival rates at 1, 5, and 10 years are listed inTable 1. Cirrhosis is the most frequent indication(50%), mainly related to either viral infection (24%),with 16% hepatitis C virus infection, or alcohol abuse

(18%). Cirrhosis is followed by three indications: cho-lestatic disease (13%), primary liver tumors (10%), andacute hepatic failure (9%). Cholestatic disease is repre-sented mainly by primary biliary cirrhosis (8%), biliaryatresia (5%), and primary sclerosing cholangitis (4%).Biliary atresia is the most frequent indication (56%) inthe pediatric population, followed by metabolic disease(21%). Hepatocellular carcinoma is the most frequentcancer (8%). Virus-related fulminant hepatitis is themost frequent cause of acute hepatic failure (2%) inEurope.

The percentage of main indications for LT haschanged significantly with time. Whereas cancers rep-resented 50% of indications before 1980, they currentlyrepresent no more than 10%. Conversely, acute hepaticfailure that led anecdotally to LT before 1986 has sincebecome a recognized indication for LT (Fig. 3).

Overall Patient Survival

When all indications are considered during the entirestudy period, patient survival rates are 80% at 1 year,70% at 5 years, and 62% at 10 years. Survival hasimproved regularly year after year, reaching 83% at 1year in 2001 compared with 76% in 1990 to 1994 andonly 34% before 1985 (Fig. 4). Currently, at 5 years,the patient survival rate is 72%. The improvement con-

cerns all indications, but particularly LT for cancers(Fig. 5).

The critical period for post-LT outcome is repre-sented by the first 6 months: 58% of deaths and 68% ofre-LTs occur within the 6 months after LT (Fig. 6). In48% of cases, re-LT is indicated in the month afterprimary LT, and one third of patients who die do sowithin the first month after LT.

Survival of Pediatric Versus Adult LiverTransplant Recipients

Eleven percent of LTs have been performed in pediatricpatients (�15 years), with 4% of children younger than2 years. Five-year survival in children is significantlybetter than in adults (76% v 68%; P � .0001). In thepediatric population, 5-year survival rates are 75% forchildren younger than 2 years and 77% for those aged 3to 15 years.

Survival According to Indication for LT

The 5-year patient survival rate is significantly better forcirrhosis (71%) than for primary liver tumors (49%;P � .001) and acute hepatic failure (59%; P � .001).The greater survival rates obtained in metabolic diseases(77%) and cholestatic diseases (73%) occur partlybecause of the high percentage of children in thesegroups. Details of survival rates at 1, 5, and 10 yearsaccording to primary indication are listed in Table 1.

Survival According to Donor and RecipientCharacteristics

Donor characteristics. The majority of donors weremale (61%). Eighty-one percent were younger than 55years, whereas 5% were older than 65 years. Graft sur-vival when organs were procured from donors youngerthan 55 years was significantly greater than that withorgans from donors older than 65 years (63% v 52% at5 years; P � .0001). An increasing percentage of liversare coming from donors older than 60 years (2% in1991, 10% in 1996, and 20% in 2001), in relation tothe increasing gap between a growing waiting list and arelatively stable donor pool (Fig. 7).

Recipient age. In addition to the already mentionedbetter survival of pediatric versus adult liver transplantrecipients, an influence of recipient age is noted foradults. Survival rates are 71% for adults aged 16 to 45years, 67% for those aged 46 to 60 years, and 63% forthose older than 60 years. However, average age oftransplant recipients has increased steadily during thelast decade, and patients older than 60 years, who rep-

resented less than 5% in the 1980s, represented approx-imately 20% of transplant recipients in 2001 (Fig. 8).

Blood group type matching. Ninety-two percent of LTswere isogroup, and 7% were compatible. Only 1% wereincompatible and restricted to urgent procedures. Inemergencies, isogroup and compatible LTs have similarsurvival. Incompatible LTs have a decreased 5-yeargraft survival rate of 24% compared with isogroup andcompatible LTs; 48% and 46%, respectively (P �.0001). However, use of these incompatible grafts inemergency indications allows an approximately 50%survival rate in patients otherwise destined to a fataloutcome.

In elective conditions, isogroup LTs have a better5-year survival rate than compatible LT (65% v 57%;P � .0001).

Survival According to Surgical Technique

More than 99% of LTs were performed orthotopically,and 89% of grafts were full size. Alternative proceduresto full-size LTs have been used increasingly in recentyears, represented by reduced livers (5%), split livers(4%) living donors (1.6%), and domino transplants(0.4%). Survival at 5 years was similar between split-liver and reduced-liver grafts (57% and 56%), but less

than that of total-liver grafts (61%; P � .0001). How-ever, split-liver transplantation in experienced centershad results similar to full-size LTs.3 Auxiliary graftsrepresented 0.4% of overall LTs, with a graft survivalsimilar to that of nonauxiliary grafts in urgent indica-tions (5-year survival rates, 45% v 47%), but not inelective cases (47% v 64%; P � .0001). Graft survivalwas better when cold ischemia time was less than 12hours and University of Wisconsin solution was usedfor preservation (P � 0.001).

Living Related LT in Europe

The ELTR has accumulated data concerning 806 livingrelated LTs (LRLTs) performed in 46 centers from 15countries from October 1991 to December 2001 (Fig.1). There were 359 LRLTs performed in adults and 446LRLTs performed in children. By the last 2 years, adultLRLT largely exceeded pediatric LT (286 v 128 proce-dures). The graft used was mainly the right liver foradults (93%) and left-liver lobe for children (84%). Thedonor surgical mortality rate was 0.5%, with four post-operative deaths related to pulmonary embolism (onedeath), sepsis (two deaths), and cardiac failure (onedeath). Donor morbidity accounted for 21% of earlypostoperative complications, greater for right-liver

(34%) than left-lobe donation (10%; P � .001). Com-pared with cadaveric LTs, there were significantly morecancers (23% v 10%), fewer acute hepatic failures (4%v 8%), and fewer re-LTs (1% v 10%). The overall5-year graft survival rate was 75%, better for childrenthan for adults (80% v 66% at 3 years). Whereas sur-vival of LRLT was better than cadaveric LT for children(80% v 70%; P � .001), it was similar for adults (66%v 68% at 3 years). Graft size had no prognostic influ-ence in children, but significantly affected the outcomeof adults (3-month graft loss, 21% for right livers, 50%for left livers, 69% for left lobes; P � .001). Overall,graft loss included more primary nonfunction (21% v13%) and technical complications (21% v 13%) afterLRLT than after cadaveric LT (P � .01).

Re-LT and Death

Main causes of re-LT. Re-LT was indicated in 4,216cases (9.5%), mainly for technical complications,mostly vascular (33%); primary nonfunction (27%);

and rejection (mainly chronic; 22%). Recurrence ofprimary disease (mostly nontumoral) was concerned inonly 8% of cases (Table 2).

Five-year graft survival rates for the second and thirdLTs were 42% and 37%, respectively. Rates was signif-icantly lower (P � .0001) than those for primary LT(63%; Fig. 9). In emergency situations, the differencein survival between primary LT and a second LT,although still significant (P � .001), was reduced (52%v 37%; data not shown).

Main causes of mortality. Main causes of death in the8,557 patients (�19%) who died after primary LT orre-LT were, by decreasing order, such general causes asmultiple organ failure and cerebrovascular, cardiovas-cular, pulmonary, and renal complications (30%); sep-sis (20%); recurrence of primary disease (mostly cancer;17%); technical complications (mostly hemorrhageand vascular; 6%); and rejection (4%; Table 3). Intra-operative deaths represented 5%, and primary non-function represented 3% of all deaths.

1239European Liver Transplant Registry Report

DiscussionWith more than 40,000 recorded LTs all over Europe,the ELTR currently is one of the most important data-bases to evaluate results of LT. It is representative of LTin Europe (95% of LTs performed). Owing to accuratecontrol of data, including audit visits to randomlyselected centers, its scientific value recently has beenemphasized.5-7

More than 4,000 LTs per year currently are per-formed in Europe. After an exponential growth fromthe 1980s, the number of yearly LTs is plateauing fromapproximately 4 years because of the lack of organs. Tocope with a donor shortage that presently represents themost important limiting factor of LT, such alternativesto cadaveric LT as split, domino, or living related LTsare increasingly used, accounting for 11% of all proce-dures. Although more technically demanding, thesetechniques give results similar to those for cadaveric LTand allow a larger number of patients to undergo LT.

One of the most important findings in the evolutionof LT is the significant improvement in results withtime; presently, a 1-year survival rate of 83%, all indi-cations confounded, in relation to greater technical

expertise, better selection of patients, and improvedpost-LT management of complications and immuno-suppressive therapy. The improvement is particularlysignificant for cancers, represented mainly by hepato-cellular carcinoma, with a gain of 17% in 5-year sur-vival rates from 1990 to 2000.

Donor and recipient age influence the quality ofresults, shown by a previous analysis of ELTR datafocused on mortality after LT.3 However, they are notprominent factors in mortality. Therefore, evolutionshows that older donors are increasingly used to aug-ment the donor pool, and older recipients increasinglyundergo LT owing to improved results and better selec-tion of patients.

What has not changed with time is the critical periodof the first 6 months and, more generally, the first yearto determine the final outcome of the transplant recip-ient. More than two thirds of deaths and more thanthree fourths of re-LTs occurred within the first yearafter LT.

When required in approximately 7% of patients,re-LT is associated with much less optimal results thanthe first LT. However, no team considers this a suffi-

cient reason to not perform a new LT, suggesting that asort of moral contract with the patient has a role to play,in addition to strict consideration of the optimal use oforgans. Interestingly, third and fourth LTs are not associ-ated with results much worse than those of second LTs.

One of the prominent features of recent years is thedevelopment of LRLT, now performed by almost halfthe centers. As with split LT, LRLT aims to providemore patients with transplants,but with special atten-tion to decrease as much as possible risks for the donor,now estimated to be 0.5% for mortality and 21% forpostoperative morbidity.

In conclusion, LT presently has reached the age ofmaturity. Indications are oriented to more optimal useof the limited donor pool. Survival is still increasing

gradually in relation to greater expertise in the surgicalprocedure and management of immunosuppressivetherapy. Alternatives to conventional use of cadavericfull-size liver grafts are expanding to palliate the organshortage. This latter development probably will repre-sent the key issue in the near future, to avoid patientdeath on the waiting list and offer LT to patients cur-rently not benefitting from this therapy.
