8. Arterial Embolization +/- Chemotherapy (TACE) Llovet, Bruix, Hepatology 2003; 37: 429-442 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

15. Molecular Classification of HCC- Expression Profiles Molecular Classification and Novel Targets in Hepatocellular Carcinoma: Recent Advancements Yujin Hoshida, Sara Toffanin, Anja Lachenmayer, Augusto Villanueva, Beatriz Minguez, Josep M. Llovet
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.

Sorafenib vs drug** Sorafenib vs Sorafenib +drug (Sorafenib) Drug vs placebo TACE vs drug or device** BCLC C- Advance stage (Chemoembolization-TACE) - TACE vs TACE + drug BCLC B-Intermediate stage (Resection, Transplantation Local ablation) - Adjuvant: drug vs placebo BCLC 0 or A –Early stages 2nd line treatment* 1st line treatment (standard of care) Testing novel drugs HCC subclass
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.“ SNL, Theodoric of York, Medieval Barber (Steve Martin)
