HCC Stage 0PST 0, Child–Pugh A Stage A–CPST0–2,Child–PughA–B Stage DPST > 2, Child–Pugh C Very early stage (0) 1 HCC < 2 cmCarcinoma in situ Early stage (A) 1 HCC or 3 nodules< 3 cm, PST 0 Intermediate stage (B) Multinodular,PST 0 Advanced stage (C) Portal invasion, N1, M1, PST 1–2 End stage (D) 1 HCC 3 nodules ≤ 3 cm Increased Associated diseases Normal No Yes Resection Liver transplantation RFA TACE Sorafenib Symptomatictreatment (20%) Survival < 3 months Curative treatments (30%) 5-year survival 40–70% Palliative treatments (50%) Median survival 11–20 months HCC staging: AASLD guidelines (updated 2010) Portal pressure/bilirubin Adapted from Bruix J, Sherman M. Hepatology. 2010.http://www.aasld.org/practiceguidelines/Documents/Bookmarked%20Practice%20Guidelines/HCCUpdate2010.pdf. Llovet JM, et al. J Natl Cancer Inst. 2008;100:698–711. AASLD = American Association for the Study of Liver Diseases; PEI = percutaneous ethanol injection; PST = Performance Status test; RFA = radiofrequency ablation.

  18. HCC Confined to the liver Main portal vein patent Extrahepatic metastasis Main portal vein tumor thrombus Resectable Child–Pugh A/B Child–Pugh C Yes No Solitary tumor ≤ 5 cm ≤ 3 tumors ≤ 3 cm No venous invasion Tumor > 5 cm > 3 tumors Invasion of hepatic/portal vein branches Resection/RFA (for < 3 cm HCC) Child–Pugh A Child–Pugh B Child–Pugh C Child–Pugh A/B Child–Pugh C Local ablation Transplantation TACE Supportive care APASL guidelines Sorafenib or systemic therapy trial APASL recommendations on HCC. Omata M, et al. Hepatol Int. 2010;4:439–74.

  19. Japan Society of Hepatology:consensus-based treatment algorithm for HCC HCC Extrahepatic spread No Yes Child–Pugh A/B Child–Pugh B/C Liver function Child–Pugh C Child–Pugh A Vessel invasion No Yes No Yes Number 1–3 4 or more Single Within Milan criteria and age ≤ 65 Within Milan criteria and age ≤ 65 Exceeding Milan criteria or age > 65 Hypovascular early HCC Size ≤ 3 cm > 3 cm Intensive follow-up Ablation Resection Ablation Resection TACE (TACE + ablation) Sorafenib HAIC TACE Resection Transplantation (TACE/ablation for Child–Pugh C patients) Palliative care Sorafenib TACEHAIC (resection + ablation) Transplantation (TACE/ablation for Child–Pugh C patients) Treatment Sorafenib (TACE refractory) TAI = hepatic arterial infusion chemotherapy. Kudo M, et al. Dig Dis. 2011;29:339–364.

  20. First-line treatment option in each mUICC stage

  21. Single, less than 2cm HCC, Child-A, no or minimal portal hypertension (BCLC-0) Resection vs. RFA; many studies LT?

  22. Single, more than 2cm HCC (BCLC-A) In case within Milan criteria

  23. Multiple, less than 2cm HCC (BCLC-A or B) In case above Milan criteria

  24. Single, less than 2cm HCC with vascular invasion (BCLC-C) According to Western guidelines Unusual presentation. Practically TACE preferred, Resection vs. TACE?

  25. Multiple, more than 2cm HCC (BCLC-B or A) Mostly TACE, LT or RFA: limitedly applied

  26. Hong Kong Liver Cancer (HKLC) classification Yau T, et al. Gastroenterology 2014

  27. Single, more than 2cm HCC with vascular invasion (BCLC-C) Which modality is the best for this kind of HCC? No data

  28. Multiple, less than 2cm HCC with vascular invasion (BCLC-C) Resection TACE may be preferred because of small tumor size

  29. Advanced HCC without extrahepatic spread (BCLC-C) Only sorafenib has evidence.

  30. Competitor (I)

  31. Competitor (II)

  32. Competitor (III) Gastroenterology 2010

  33. HCC with extrahepatic spread (BCLC-C)

  34. Conclusions • HCC incidence in Korea is slightly decreasing. • Still a major cancer related with significant mortality • Prognosis is being improved due to proper management • Selection of first treatment option does not always depend on evidence. • Guideline are just guidelines. • Heterogeneity of HCC presentation makes it difficult to keep algorithm for selecting treatment option.
