8. Arterial Embolization +/- Chemotherapy (TACE)
Meta- Analysis of Randomized Trials
• TACE improved 2 year survival vs
control: odds ratio: 0.53 (.32-.89),
P=0.017
• Benefit with use of Cisplatin and
Doxorubicin
• NO survival benefit with embolization
alone
• Response rate: 35% (16 %- 61%)
• Optimal patients for TACE: well
preserved liver function, multi- nodular
HCC, no vascular invasion
Llovet, Bruix, Hepatology 2003; 37: 429-442
10. Hormonal Rx of HCC
Tamoxifen:
One clinical study suggests benefit, several others do not-
considered largely ineffective
Octreotide:
One clinical study suggests benefit, several others do not-
considered largely ineffective
Thalidomide (? Mechanism)
Multiple trials with at best minimal efficacy
(Revlimid more potent)

16. Regulatory Control- Micro RNAs
Fig. 1 Schematic representation of
pathways affected by miRNAs
deregulated in human hepatocellular
carcinoma . Receptor tyrosine
kinase (here indicated HGF/MET
axis solely), RAS and PI3K
pathways affected by the down-
regulated (downward green arrow)
miR-1, miR-199a*, Let-7 and the up-
regulated (upward red arrow) miR-
21 may lead to cell
growth, survival, motility, invasion
and metastasis. The cell cycle
progression is mainly affected by the
miR-221 (and miR-222, not
indicated) up-regulation, which can
repress the CDK inhibitors CDKN1
B/p27 and CDKN1 C/p57.

27. Molecular Targeted Drugs for HCC-
Multi- kinase Inhibitors
Sunitinib (Sutent); Targets: VEGFR, PDGFR, CKIT Small Molecule Multi- kinase
inhibitor
Side Effects: Fatigue, Diarrhea, Anorexia, Vomiting, HTN
Phase II: 30- 40% of patients have period of cancer control
Phase III:
Sunitinib vs sorafenib, failed; sunitinib with more side effects without additional efficacy-
trial closed early for lack of benefit
Brivanib, Targets: VEGF, FGFR
Small Molecule Multi- kinase inhibitor
Phase II: Second line- after sorafenib
58% stable disease, 43% AFP drop > 50%
Phase III: ongoing trials Brivanib vs BSC, TACE +/- Brivanib
28. Summary- Challenges
• Sorafenib first systemic agent with proven
efficacy in Rx of HCC- future studies
• Modalities and techniques (Surgery/ Loco-
regional/ systemic/ RT) need to combined
and integrated rationally
• Drug glut
• Increasing number of targets
29. HCC Clinical Trials @ Montefiore/ Einstein
Pfizer A6181170 Phase III HCC study: Sunitinib Malate
Versus Sorafenib in Patients with Advanced
Hepatocellular Carcinoma- closed to accrual, more
toxicity with sunitinib
Lenalidomide (Revlimid) phase II study for advanced HCC
(Safran- Brown), for patients who have received
sorafenib
Bristol Phase III: Brivanib (VEGFR, FGFR) vs placebo
after TACE, Can Brivanib prevent or delay recurrence
after TACE?
NY Consortium 8233 Phs. II Trial of Temsirolimus (mTor)
& Bevacizumab (VEGF).
30. Proposed Standards for Future Clinical
Trials in HCC

BCLC 0 or A –Early stages Adjuvant: drug vs placebo -
(Resection, Transplantation Local ablation)
BCLC B-Intermediate stage TACE vs TACE + drug -
(Chemoembolization-TACE)
BCLC C- Advance stage TACE vs drug or device** Drug vs placebo

31. Clinical and Translational Reasearch Opprtunities in
Liver Cancer at AECOM/ Monte
1) Tissue Banking- Molecular Profiling; large patient population will lead
quickly to meaningful tissue bank (identification of prognostic or
treatment guiding biomarkers?)
2) Therapeutic trials
A) Enhancements to Local treatments: TACE + novel agents, TACE +
RT?, TACE + RFA as standard local Rx
B) Can local ablative techniques (TACE, RFA, HIFU, RT etc) generate
auto- immunizing antigens, perhaps with in vivo dendritic cell
stimulation?
C) Can moderate doses of 2 separate local therapies result in better
cancer control with an improved therapeutic index? (eg SIRT and drug-
eluting beads)
D) Rational combinations of biologic agents (eg mTor/ EGFR inhibition)
E) How can we enhance the efficacy of radiation in the treatment of
HCC
3) All of the above with correlative science to enhance our understanding
of the biology of liver cancer
32. "You know, medicine is not an exact science, but
we are learning all the time. Why, just fifty years
ago, they thought a disease like your daughter's
was caused by demonic possession or witchcraft.
But nowadays we know that Isabelle is suffering
from an imbalance of bodily humors, perhaps
caused by a toad or a small dwarf living in her
stomach.“

2 phosphorylation, decreased microvessel density, growth
inhibition) CCR 2008, 14:6146-53
