Patient survival after liver transplantation has shown continued improvement
• The last 10 yrs have seen steady improvements in pt survival in Europe, the US, Australia & New Zealand1–3
– 1-year post-transplant survival of ≈ 90%
– These improvements are due to advances in peri-operative care, perfection of surgical technique, introduction of potent immunosuppressants, antibiotics & antiviral drugs4

In the face of donor organ shortage, Organ Allocation is determined by MELD score
• MELD scale provides a predictive measure of short-term mortality risk & prognosis in patients with ESLD1,2
– MELD score is based on laboratory indicators of renal dysfunction (serum creatinine), liver disease (serum bilirubin) and bleeding risk (INR for prothrombin time)
• The higher the MELD score, the higher the priority for a liver transplant
• In the MELD era, patients with ESLD and poor renal function have become increasingly common candidates for liver transplantation3
• Allocation of donor livers is based on MELD scores in most countries
ESLD, end stage liver disease; MELD, Model for End-stage Liver Disease; INR, international normalized ratio1. Malinchoc M et al. Hepatology 2000;31:864-871;2. Kamath PS et al. Hepatology 2001;33:464-470;3. Sharma P et al. Liver Tranpl 2009;15:1142-48
MELD score: 6- 40• Serum Bilirubin, serum Creatinine & INR to predict survival
• Patients dialyzed twice within the last 7 days, value for serum creatinine should be 4.0

Extended Criteria Donors (ECD)Marginal Donors
• Ideal Donor: Age<40, trauma as cause of death, donation after brain death (DBD), haemodynamic stability at time of procurement, no steatosis or any underlying liver disease & no transmissible diseases (infectious/ malignant).
• ECD: Any donor who does not fit these criteriaSRTR Data: increased utilization of elderly donors, DCD &
donors with positive markers of HBV & HCV
• Implications: 1ry graft nonfunctioning Early graft poor function
Transmission of donor derived disease
Death or need for re-transplantation
Donor after Cardiac Death (DCD)
• Def. Organ procurement after a standoff period of 5 min. after death is certified
• Implications: variable period of warm ischemia time that may result in early poor function, non-function of the graft or diffuse cholangiopathy
• Measures to halt deleterious effects on graft function: judicious donor selection (age<40, no steatosis), use of heparinized perfusate, use of extracorporeal oxygenation, short WIT (<15 min) & short CIT (<10 hrs)
Deshpande R, Heaton N: J.Hepatology 2006; 45: 499
Donor Assessment
• Age 18-50• BMI < 30• No Co-morbid disease• Phase I: ABO blood group compatibility & Blood
chemistry (CBC, Liver and Kidney function)• Phase II: Virology markers (e.g. Anti HCV antibodies,
Anti HBV antibodies, etc)• Phase III: CT scan anatomy & Volumetry.• Phase IV: Liver biopsy, Medical consultation (e.g.
Cardiac , Chest & Psychiatric consultation)
Donor Assessment
Volume of harvested lobe should be ≥ 1% of the recipient weight:
GRWR ≥ 0.8%
Recipient Assessment
• History – Etiology of liver disease– Previous liver transplantation– GIT hemorrhage– Ascites– History of SBP– History of encephalopathy– Surgical history– Medical history eg, diabetes, hypertension, ischemic
heart disease• Child-Pugh & MELD score
Recipient Assessment
CVS assessment:› Clinical examination› ECG› Echocardiography (pulmonary hypertension; cardiomyopathy, etc)› Dobutamine Stress echo
Respiratory assessment› Clinical examination› Chest x-ray› Pulmonary function tests
Renal assessment› Urea and serum creatinine &Creatinine clearance
ENT and dental examination› Exclude septic foci
Imaging and laboratory investigation
Surgical Team
Technique
• Cadaveric full size• Split
Split liver transplantation
• Partial liver graft Tx was initially suggested by Smith in 1969.
•Reduced liver graft was reported by Bismuth & Houssin 1984.
•Pichlamyr & Bismuth reported successful split liver transplant 1989
Technical Aspects of LDLT
Interrelationship for Technically Successful LDLT
Surgical procedures
• The two surgical techniques are performed simultaneously; the donor procedure last 6-8 hrs while the recipient procedure 10-12 hrs
• The donor spend the first 24- 48 hrs post-op in the ICU & an 6- 10 days in hospital
• The two half-livers (both in donor and recipient) grow back to 80% of their size in 3-4 weeks

HCV recurrence post-transplant is a key unmet need in HCV patients

Liver transplant
Recurrence of infection: >98%
Acute hepatitis: 25–45%
• HCV-related chronic hepatitis: 80–100%• HCV-related graft cirrhosis: 8–30%• Cholestatic hepatitis: 2–8%
Follow-up: 3.5 months (1–13 months)
Follow-up: 5 years
• HCV reinfection is “Universal”1–5
• Early & aggressive HCV recurrence significantly accelerates the progression of the disease, compared with HCV in the non-transplant population1–5
• HCV Recurrence after LTx is associated with
– Accelerated fibrosis progression– Accelerated graft cirrhosis– Reduced graft survival– Reduced pt survival
• Reducing the use of CNIs & Steroids appears to slow the progression of HCV6

Are Neo-Adjuvant Locoregional Treatment Indicated in pts listed for LT ?
• Bridge Therapy: No recommendation could be made on bridging therapy in pts with UNOS T1 HCC .
• A cost-effective analysis based on Markov
model & the review of cohort studies indicate a benefit for bridging therapies if the waiting time is expected to be > 6 months to avoid TP.
Definitions of Down-staging before transplantation
Toso C, et al. J Hepatology. 2010;52:930-6.
Neo-adjuvanttreatment
Down-staging
To decrease tumor progression
and hence dropout from the
waiting list
To improve long-term results To select pts with good
long-term outcomes among
poor risks pts.
(Response to ttt & observation time
used as a surrogate markers for
favorable biology)
To bring patient whose tumor
burden is outside accepted
criteria for Tx to within acceptable
criteria.
Before transplantation
Which is the best neo-adjuvant treatment in Pts considered for LT?
Locoregional therapy Indications Risks Benefits
RFA Small HCC (usually 3 cm), away from the liver surface,
away from major vessels
HCC seeding (1–2%) liver rupture (small)
• OK even in case of decreased liver function
• Only one session usually required
• Complete necrosis in 90% of cases
TACE Any HCC size preserved liver function (Child–Pugh A-B)
uptake of contrast
Liver failure arterial injury (2%)
• OK even for large HCCs
TARE Any HCC preserved liver function (Child–Pugh A-B),
absence of intra-hepatic shunt, uptake of contrast
Off-target embolization arterial injury
• OK even for large HCCs (up to 10 cm?)
• OK even in case of portal vein thrombosis more efficient than TACE (to be confirmed)
• Shorter time to response (to be confirmed)
Toso C, et al. J Hepatology. 2010;52:930-6.
Response to therapy is a potentially effective tool for prioritizing HCC patients for liver transplantation

Everolimus + low Tac demonstrated a Comparable Safety profile with standard Tac
aThe incidence of clinically relevant proteinuria above 3 g/day in the everolimus + low Tac group was comparable to that in the standard Tac group. Patients with proteinuria ≥0.5 g/24 hrs at one month post-transplant had no progression to more severe proteinuria with everolimus + low Tac.

Both Sirolimus (P≤ 0.05) & Anti-CD25 Antibody induction (P≤ 0.01) demonstrated significantly improved survivals after LTx for HCC.

No sense of accomplishment can exceed that of seeing a robust LT recipient who, a few weeks earlier, was seemingly near death from ESLD.
Summary
• Successful LTx requires optimal patient selection and timing of Tx.• Indications across most centers are similar, however, a regional
difference exists with HCC & metabolic reasons being on the rise. • To date, MELD score is the most accurate to predict early outcome of
LTx & to prioritize organ allocation including that for HCC patients.• Organ shortage is currently tackled by: ECD & Surgical innovation. • Current unmet needs following LTx include: minimizing CNI toxicity,
CKD, HCV & HCC recurrence.• Introduction of new immunosuppressant with less severe AEs and
equivalent anti-rejection efficacy are urgently needed with mTORi emerging as a new player in this context.
