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

Page 20: Ain sh ams, feb 2014 liver transplant

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

Page 23: Ain sh ams, feb 2014 liver transplant

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

Page 24: Ain sh ams, feb 2014 liver transplant

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)

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)

Page 27: Ain sh ams, feb 2014 liver transplant

Donor Assessment

Volume of harvested lobe should be ≥ 1% of the recipient weight:

GRWR ≥ 0.8%

Page 28: Ain sh ams, feb 2014 liver transplant

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

Technique

• Cadaveric full size• Split

Page 32: Ain sh ams, feb 2014 liver transplant

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

Page 36: Ain sh ams, feb 2014 liver transplant

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.

Page 50: Ain sh ams, feb 2014 liver transplant

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

Page 51: Ain sh ams, feb 2014 liver transplant

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.

CNI minimization in liver transplant patients

…… but High level exposure to CNIs is a well-recognized risk factor for chronic kidney disease in liver transplant recipients1

Attempts to withdraw CNI have lead to increased risk of

acute rejection2,3

CNI minimization can help tip the balance between adequate

immunosuppression and exposure to CNIs2

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.

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.
