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.

The impact of irritable bowel syndrome on health-related quality of life: a Singapore perspective.

BACKGROUND: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder. The prevalence of IBS in Asian countries varies from 2.9% to 15.6%. IBS does not result in increased mortality, but is associated with psychological distress and disruption of work and sleep. Consequently, the evaluation of health-related quality of life (HRQoL) is an important outcome measure for patients with IBS since it provides a holistic assessment of the patient's emotional, social and physical function. However, some HRQoL tools can be time-consuming to apply. EQ-5D is a brief HRQoL tool which has been validated in the Western IBS population but has thus far not been used in Asia. This study was conducted to determine whether persons with self-reported symptoms that met the Rome III criteria for IBS had a poorer quality of life than those without these symptoms. We also aimed to determine which specific aspects of quality of life were most affected and whether any risk factors distinguished those with and without IBS. METHODS: Self-administered questionnaires which included the Rome III diagnostic questionnaire modules for IBS and the EQ-5D questionnaire were obtained from participants of a health symposium in Singapore on 31th October 2010. IBS was diagnosed based on the Rome III Criteria. The main outcome measure was the EQ-5D index score. The relationship between the presence of IBS and the EQ-5D index score, individual dimensions of EQ-5D and demographic risk factors were examined. RESULTS: 449 completed questionnaires were analyzed. The mean EQ-5D index score for IBS was 0.739 which was a significant reduction compared to non-IBS participants [-0.11 (95% CI: -0.15 to -0.07), p<0.001]. Multivariate analysis showed that IBS was significantly associated with younger age and higher education level. Of the five EQ-5D dimensions, IBS sufferers were significantly affected in mobility, anxiety or depression, usual activity and pain. There was a "dose related" increase in likelihood of having IBS with increased severity of pain and anxiety or depression. CONCLUSION: IBS sufferers have significantly poorer quality of life. Assessment of HRQoL in IBS using the EQ-5D should be considered in further studies and routine clinical practice.
