Future developments AASLD-JNCI guidelines in HCC Trial design Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71. HCC trial design strategy recommended by AASLD expert panel Early clinical research phase Phase 1/2 study Randomized phase 2 Advanced clinical research phase Combined phase 2–3 Phase 3 study Combined phase 1/2 studies in cirrhotic patients will capture liver-specific toxic effects of new drugs Randomized phase 2 trials are pivotal in HCC research because they enable reliable comparison with standard of care Phase 3 studies remain the main source of evidence in HCC research Phase 2/3 studies may be appropriate in very specific circumstances, where the drug proposed would require fast-track assessment Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71. Endpoints in clinical trials recommended by AASLD expert panel Recommended primary and secondary endpoints Survival Time from randomization to death. Patients alive at the end of follow-up are censored •Primary endpoint in phase 3 studies assessing primary treatments •Primary/secondary endpoint in phase 2/3 studies assessing adjuvant or neoadjuvant treatments •Secondary endpoint in phase 2 studies assessing primary treatments Time to recurrence (TTR)* Time from randomization to recurrence. Evidence of recurrence should follow the RECIST amendments. Once evidence of HCC recurrence is confirmed, TTR will be defined as the time that recurrence was first suspected •Primary/secondary endpoint in phase 2/3 studies assessing adjuvant or neoadjuvant treatments Time to progression* Time from randomization to radiological progression. Definition of progression is based on the RECIST amendments. Deaths during follow-up without evidence of radiological progression are censored •Primary endpoint in phase 2 studies assessing primary treatments •Secondary endpoint in phase 3 studies assessing primary treatments Time to local recurrence* Time from randomization to local radiological progression. Definition of progression is based on the RECIST amendments. Deaths during follow-up without evidence of radiological progression are censored •Secondary endpoint in studies assessing locoregional therapies *Time to progression and time to local recurrence can vary considerably if evaluation interval varies among studies or between study arms of an individual study. RECIST = Response Evaluation Criteria in Solid Tumors. Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71. Endpoints in clinical trials recommended by AASLD expert panel Recommended primary and secondary endpoints Tertiary endpoints† Cancer-specific death Time from randomization to HCC-related death. Patients alive at the end of followup are censored •Competing risk analysis is recommended to assess this endpoint Time to symptomatic progression Time from randomization to deterioration of symptoms as assessed by a standardized questionnaire •No reliable questionnaires have been thoroughly validated in HCC research Disease-free survival Composite endpoint. Time from randomization to either recurrence or death. Patients alive and free of recurrence at the end of follow-up are censored •Vulnerable endpoint in HCC research Progression-free survival Composite endpoint. Time from randomization to either radiological progression or death. Patients alive and free of progression at the end of follow-up are censored •Vulnerable endpoint in HCC research Response rate Definition of response is based on the RECIST amendments † Tertiary endpoints include composite endpoints that are vulnerable in HCC research, such as disease-free and progression-free survival, that are difficult to measure with standard tools, such as time to symptomatic progression, or that are not time-to-event endpoints, such as response rate or disease control rate. RECIST = Response Evaluation Criteria in Solid Tumors. Llovet JM, et al. J Natl Cancer Inst. 2008;100:698-71. Other recommendations of AASLD expert panel on HCC trial design Target population • selection of the target population should be based on the Barcelona Clinic Liver Cancer staging system • new drugs should be tested in patients with well preserved liver function (Child–Pugh A class) Control arm in clinical trials • patients assigned to the control arm should receive standard-ofcare therapy, namely TACE for patients with intermediate-stage disease and sorafenib for patients with advanced-stage disease Llovet JM, et al.

Outcome prediction in HCC Model of HCC prognosis combining clinical and genomic data In patients with early stage tumors, survival is mostly determined by genomic data coded in non-tumoral cirrhotic tissue (‘field effect’), because it determines the risk of liver dysfunction and development of a de novo HCC As cancer progresses, genomic data from the tumor increases its prediction capacity because cancer-related death limits survival in patients with advanced disease Relative prognostic impact of molecular data from tumor and adjacent tissue Clinical stage (BCLC algorithm) Very early (Stage 0) Early (Stage A) Intermediate (Stage B) Advanced (Stage C) Single nodule < 2 cm, no vascular invasion, PST 0 Single nodule, 3 nodules < 3 cm, no macrovascular invasion, PST 0 Multiple nodules, no macrovascular invasion, PST 0 Macrovascular invasion, extrahepatic spread (N1, M1), PST 1–2 De novo tumor Liver dysfunction Intrahepatic dissemination Tumor biology Others Tumor Adjacent tissue © 2010 American Association for Cancer Research` Villanueva A, et al.
