Challenge of Milan Criteria

Yao F et al, Am J Transpl, 2008

What are the criteria for OLT? LT within the Milan criteria (1 tumor 70% 5-yr survival UCSF criteria (1 tumor ≤ 6.5cm, ≤ 3 with the largest ≤ 4.5 cm and total tumour Ø ≤ 8 cm) : same outcome in retrospective studies

What are the criteria for OLT? Recommendation Level of evidence Strength 1.The Milan Criteria are currently the benchmark, and the basis for comparison with other suggested criteria. 2bStrong 2.A modest expansion of the number of potential candidates may be considered on the basis of several studies showing comparable survival for patients outside the Milan criteria. 3bWeak 3.Patients with worse prognosis may be considered for OLT outside the Milan criteria if the dynamics of the waiting list allow it without undue prejudice to other recipients with a better prognosis. ØWeak

Negative risk factors of survival for HCC Multifocal tumor Size of tumor Poor differentiation Lympho/ vascular invasion AFP > 400 – 1000 ng/ml

Allocation for Liver TPL Model for End-stage Liver Diseases: MELD Score 2002 «United Network for Organ Sharing» (UNOS): To grade patients on the waiting list according to the severity of liver disease Serum Creatinine (mg/dl) Bilirubin (mg/dl) INR Score Wiesner R et al., Gastroenterology, 2003 Kamath PS et al, Hepatology x (0.957 (Serum Crea) (Bilirubin) (INR) )

Allocation for Liver TPL Model for End-stage Liver Diseases: MELD Score Highly predictive of the risk of dying from liver disease for patients on the waiting list Switzerland: Allocation according to MELD since 2007

Allocation: Problem HCC - MELD Patients with HCC often have low MELD score Long waiting time for Liver TPL Extra points T1(< 2 cm) +0 pts 33% OLT without HCC ! T2 (2-5 cm) 22 pts T3 – T4: +0 pts negative prognostic UNOSEurotx Minimum 22 Upgrade 10% MELD equivalent (3 months) Swisstx MEDIAN of the MELD score of all liver-patients of the month before: 14 1pt in addition every month on the waiting list

Allocation: Problem HCC - MELD Tumor progression Tumor growth Risk of Drop-out (2-4% / mt) Loss of benefit of TPL Transplantation TPL Decision Vascular invasion CH: waiting time: months for HCC patients

Allocation: Problem HCC - MELD Contrast imaging every 3 mt (MRI) Consequences of long waiting time: 1. Monitoring - Trans-Arterial-Chemoembolization (TACE) - Percutaneous treatment (RFA) - Resection 2. Bridging

Trans-Arterial-Chemoembolisation as Bridge

AUTHORYEARnConclusions Maddala No survival advantage after LT Perez No survival advantage after LT Decaens No survival advantage after LT Yao Survival advantage for T2/T3 Porret No survival advantage after LT Kim et al., JACS, 2007 Only retrospective studies!

Trans-Arterial-Chemoembolisation as Bridge Improvement of long-term survival: unclear No increase of post-operative complications Insufficient evidence about TACE benefits Impact of hyperselective TACE ? Lesurtel et al, Am. J. Transplant. 2006

Radiofrequency Ablation as Bridge No randomized studies Controversial results Morbidity 2,2%, mortality 0,3% Good option for Child A-B patients with expected waiting time >6 months Kim et al, JACS, 2007 Lau et al, Ann Surg 2009

Resection as Bridge Salvage OLT Without recurrence With recurrence

Resection as Bridge Belghiti J et al., Ann Surg 2003; 238: Primary OLT Secondary OLT after liver resection n = 70n = 18 Morbidity Mortality 36 (51%) 4 (6%) 10 (56%) 1 (6%) (Within Milan)

Resection as Bridge “OLT after liver resection is associated with an increased risk of recurrence and poorer outcome than primary OLT“ Years Disease-free survival Primary LT (n=195) LT after resection (n=17) 29% 64% 58% p=0.003 Adam R et al. Ann Surg,2003

Resection as Bridge 61 Resection of HCC within the Milan criteria Mean follow-up 4.3 years Recurrence present 31 (51%) Salvage LT possible: 24 out of 31 (77%) Cherqui D et al., Ann Surg year survival: 85%

Is treatment of HCC on the waiting list necessary? RecommendationLevel of evidenc e Strengt h 1.Based on current absence of evidence, no recommendation can be made on bridging therapy in patients with UNOS T1 (<2cm) HCC. ØNone 2.In patients with UNOS T2 HCC (1 nodule 2-5cm or ≤3 nodules each ≤3cm) and a likely waiting time longer than 6 months, loco-regional treatment may be appropriate. 4Weak 3.No recommendation can be made for preferring any type of loco-regional therapy over others. ØNone

Does a patient qualify for OLT after downstaging? Recommendation Level of evidence Strength 1.Transplantation may be considered after successful downstaging. 5Weak 2.Criteria for successful downstaging should include tumor size and number of viable tumors. AFP may add additional information. 4 Strong/ Weak 3.LT after successful downstaging should achieve a 5yr survival comparable to that of HCC patients who meet the criteria for LT without requiring downstaging. 5Strong 4.Based on existing evidence, no recommendation can be made for preferring a specific locoregional treatment for downstaging over others. ØNone

Living Related Liver Transplantation Disadvantages Donor Mortality : 0,2% Donor Morbidity: 16% Technically more demanding

Living Related Liver Transplantation Clavien et al., J Hep, 2009

V A What is the role of adjuvant therapy after LT for HCC? Recommendation Level of evidence Strength 1.The current evidence does not justify the routine use of adjuvant anti- tumour therapy after LT for HCC outside of a controlled clinical trial. NAWeak

Conclusions Milan criteria is the standard to select cirrhotic patients with HCC for liver TPL Survival after Liver TPL (HCC and other patients): 85% 1y, >70% 5y Allocation of Donor organs base on MELD score of recepients Resection/ Ablation and Transplantation should be associated rather than opposed Living related liver transplantation is one option to reduce shortage of organs
