HCC
Who & how ?
Who would be benefit? No standard census
Suggested best target group of patient
Well preserved liver function
Multi-nodular HCC without vascular invasion
How should we apply? No standard treatment
schedule 2 positive RCT:
treatment schedule - 2.8~4.8/patients
No standard embolization agent
Further RCT to explore optimal target population, active therapies
Advance in embolization agent

Combination Therapy
Conclusion
Untreated unresectable HCC had a poor prognosis with median survival of 3 months
TACE offer survival benefit in well selected case
Further study was indicted for explore the optimal target patient, treatment schedule and agent
Evaluation of advance in transarterial therapy and combination therapy for unsectable HCC was indicted

Stage 0 Fully active, normal life, no symptoms.
Stage 1 Minor symptoms, able to do light activity.
Stage 2 Capable of self-care but unable to carry out work activities. Up for more than 50% waking hours
Stage 3 Limited self care capacity. Confined to bed or chair > 50% waking hours.

Response rate
Response rate
Complete response: complete disappearance of tumor on imaging or normalization of serum -fetoprotein.
Major response: if tumor size or serum-fetoprotein decreased by more than 50% of the baseline measurement and
Minor response: if the reduction was 50% or less but more than 25%.
Stabilization: variations fo 25% of the initial value Progression: increase of more than 25%. Objective response was defined as the sum of complete an
d major responses.
Response rate (WHO)
Complete response: complete disappearance.
Partial response: decreased > 50% No response: decreased < 50%, increased
< 25% Progression: increase > 25%. Objective response = complete + partial
responses.
Indication for resection
