Coriolus versicolor (Yunzhi) Use as Therapy in Advanced Hepatocellular Carcinoma Patients with Poor Liver Function or Who Are Unfit for Standard Therapy.

BACKGROUND: The majority of patients with hepatocellular carcinoma (HCC) are inoperable and results with conventional chemotherapy are dismal. Many end up with no treatment options and resort to alternative medicine. The authors report the use of Coriolus versicolor (CV) in advanced HCC patients with poor liver function or who were unfit to receive standard therapy. METHODS: Fifteen eligible cases were randomized 2:1 to either CV or placebo. The primary endpoint was the median time to progression (TTP) between both arms. Secondary endpoints include evaluating response rates, toxicity, quality of life (QOL), progression-free survival (PFS), and overall survival (OS). Further correlative studies were performed looking at the effect of CV on the immune system. RESULTS: The median treatment duration was 1.5 cycles and 3 cycles on the placebo and CV arm, respectively. Median TTP was 2.5 (1.4-5.3) months compared to 4.2 (0.4-4.2) months in the CV and placebo arm, respectively, hazard ratio (HR) 0.70 (0.16-3.05 p = 0.634). Median PFS was 2.5 (1.4-5.3) months in the CV and 1.1 (0.4-4.2) months in the placebo arm, HR 0.42 (0.13-1.34, p = 0.144). Median OS was 6.5 (3.3-24.1) and 2.2 (0.8-23.3) months, respectively, HR 0.35 (0.10-1.25, p = 0.105). Social and emotional functioning scores were higher in the CV group compared to placebo group on treatment. CV subjects had less appetite loss and pain symptoms compared to placebo subjects during treatment. CONCLUSIONS: There was no difference in TTP with use of CV compared to placebo. CV subjects generally had better QOL on treatment compared to placebo subjects. The utility of this supplement in patients whose primary treatment goal is palliation should be further explored.

Peretinoin as an adjuvant therapy for hepatocellular carcinoma.

INTRODUCTION: The current curative treatment modalities for hepatocellular carcinoma (HCC) are unfortunately fraught with high rates of HCC recurrence. Hence there is a need to prevent or reduce HCC recurrence after initial curative therapy. Peretinoin is a synthetic oral retinoid showing significant reduction in the incidence of recurrent or new HCC in patients who had received curative HCC therapy. Areas covered: Peretinoin is analysed against the background of molecular pathogenesis of the different causes of HCC. Publications related to peretinoin since 1996 are reviewed, covering clinical characteristics, safety and tolerance profile as well as the current status of clinical development. Expert commentary: Early phase studies are promising but we need to await the results of the ongoing phase III study of peretinoin in hepatitis C related HCC. Long term impact of peretinoin may be diminished by the foreseeable near eradication of hepatitis C by the direct acting antivirals.

Consensus recommendations and review by an International Expert Panel on Interventions in Hepatocellular Carcinoma (EPOIHCC).

Hepatocellular carcinoma (HCC) presents with a high burden of disease in East Asian countries. Intermediate-stage HCC as defined by the Barcelona Clinic Liver Cancer (BCLC) staging system poses a clinical challenge as it includes a heterogeneous population of patients that can vary widely in terms of tumour burden, liver function and disease aetiology. Intermediate HCC patients often have unsatisfactory clinical outcomes with repeated transarterial chemoembolization (TACE, due to non-response of the target tumour or the development of further metastasis indicating progressive disease. In September 2011, an Expert Panel Opinion on Interventions in Hepatocellular Carcinoma (EPOIHCC) was convened in HK in an attempt to provide a consensus on the practice of TACE. To that end, current clinical practice throughout Asia was reviewed in detail including safety and efficacy data on TACE alone as well as in combination with targeted systemic therapies. This review summarises the evidence discussed at the meeting and provides expert recommendation regarding the available therapeutic options for unresectable intermediate stage HCC. A key consensus of the Expert Panel was that in order to improve patient outcomes and long-term survival, the possibility of using TACE in combination with targeted agents given systemically should be explored. While the currently available clinical data is promising, the expected completion of several pivotal phase II and III RCTs will provide further evidence in support of the rationale for combination therapy regimens.
