- Brief Summary
A randomized, double-blinded, placebo-controlled clinical trial using a Chinese Medicine 'Coriolus Versicolor for improving the quality of life of patients with advanced-stage cancer. Subjects will be randomized into a treatment group or placebo group for 6 months.
- Detailed Description
According to the Compendium of Materia Medica, a classic encyclopedia for Chinese medicines written by the venerated Physician Li ShiZhen of the Ming dynasty, Yunzhi (Coriolus Versicolor) is treasured as a superbly valuable herb as it not only can strengthen and consolidate the body's resistance, as well as reinforce and nourish a person's marrow and kidney essence and also is harmless to patients. Recent research found that the extract from Yunzhi, named as polysaccharide-peptide (PSP), could inhibit the growth of human hematoma cell line \& sarcoma and was proved to have direct anti-cancer effects.
Quality of life (QOL) of patients is the ultimate goal of palliative care as endorsed by the World Health Organization (WHO) in 1990. When survival is limited in advanced incurable diseases, quality of life is most important. Patients with advanced cancer (palliative) often manifest numerous physical and psychological symptoms and a poor quality of life. While maintenance of the quality of life of advanced cancer patients is important, the physical dimension of quality of life still needs improvement, especially in the palliative stage. To date, there is no specific supportive Traditional Chinese Medicine(TCM)-related products that have been proven in randomized controlled trials for alleviating these debilitating symptoms and improving their quality of life. The present study aims to scientifically evaluate whether a Yunzhi product named G.E. Yunzhi-Essence is effective and safe in improving the QOL of palliative patients with advanced cancer.

Group Intervention Description Placebo Placebo Subjects will take 2 placebo capsules, 4 times daily, for 6 months Active treatment (Yunzhi Essence) Yunzhi Essence Subjects will take 2 Yunzhi capsules, 4 times daily, for 6 months.
- Primary Outcome Measures
Name Time Method Score change of McGilll QOL-Hong Kong 6 months McGill QOL-Hong Kong questionnaire will be used to measure the quality of life of subjects. It consists of 16 items and also a single item rating the overall QOL. All the response categories are based on a numerical scale from 0 to 10, with verbal anchors at the ends of the scale. The higher the score, the better the quality of life.
- Secondary Outcome Measures
Name Time Method Use of rescue pain medication From baseline to 6 months Number of rescue pain medication will be record during the study period
Changes in tumor marker level 6 months When cancer occurs, a substance called "tumor marker" will appear in the body. It may be a by-product of cancer cells or the body's response to the tumor. Most tumor markers are proteins that can be detected in blood or urine come out. Tumor markers help to determine the possibility of cancer in some patients. One of the most important uses of tumor markers is to monitor the progress of patients during treatment.
The blood sample will be taken for measuring the tumor marker on month 6.Number of interventional medical treatments From baseline to 6 months Total number of interventional medical treatment will be records during the study period
Level change of Alanine Transaminase (ALT) From baseline to 6 months Blood samples will be taken for Liver function test(LFT). Alanine Transaminase (ALT) will be measured.
Survival rate From baseline to 6 months Survival rate will be measured from baseline to month 6
Changes in immunological levels 6 months T Serum immunoglobulins levels such as immunoglobulin A (IgA), immunoglobulin G (IgG) and immunoglobulin M (IgM) are key immunological markers for the humoral immune status. The levels of IgA, IgG and IgM are determined routinely in clinical practice to give the doctors important information about the immune system function, especially relating to infection or autoimmune diseases.
Score change of Edmonton Symptom Assessment System (ESAS) 6 months The ESAS includes 11 common patient symptoms: pain, tiredness, nausea, depression, anxiety, drowsiness, appetite, sleep, well-being, shortness of breath, and "other". It uses a 0-10 numerical scale: 0 indicates the absence of a symptom, and 10 indicates the worst experience of the symptom.
Level change of Uric acid From baseline to 6 months Blood samples will be taken for Renal function test (RFT). Uric acid will be measured.
Level change of Blood urea nitrogen (BUN) From baseline to 6 months Blood samples will be taken for Renal function test (RFT). Blood urea nitrogen (BUN) will be measured.
Level change of Alkaline Phosphatase (ALP) From baseline to 6 months Blood samples will be taken for Liver function test(LFT). Alkaline Phosphatase (ALP) will be measured.
Level change of Gamma-glutamyl Transferase (GGT) From baseline to 6 months Blood samples will be taken for Liver function test(LFT). Gamma-glutamyl Transferase (GGT) will be measured.
Level change of blood markers From baseline to 6 months Blood samples will be taken for Complete blood count (CBC)
Level change of total bilirubin From baseline to 6 months Blood samples will be taken for Liver function test(LFT). Total bilirubin will be measured.
Level change of Aspartate Transferase (AST) From baseline to 6 months Blood samples will be taken for Liver function test(LFT). Aspartate Transferase (AST) will be measured.
Level change of Creatinine From baseline to 6 months Blood samples will be taken for Renal function test (RFT). Creatinine will be measured.
Level change of Sodium From baseline to 6 months Blood samples will be taken for Renal function test (RFT). Sodium will be measured.
Level change of Potassium From baseline to 6 months Blood samples will be taken for Renal function test (RFT). Potassium will be measured.
Change of urine analysis 6 months Urine sample will be taken for urine protein analysis.
Change in Chinese medicine symptom score 6 months Chinese medicine practitioners will assess subjects' symptoms in month 6, the symptoms such as bloating, less appetite, fatigue and defecation.
