TCM as an Adjuvant Treatment in Breast Cancer Patients

Universiti Tunku Abdul Rahman30 enrolled

Overview

Chinese herbs can alleviates the side effects caused by conventional treatment in breast cancer patients and affects the syndrome element differentiation by altering the specific set of proteomes at specific time point of treatment.

The previous studies have reported that adjuvant Chinese herbs therapy can improve the survival of breast cancer patients by alleviating the side effects of conventional treatments. Protein expression determines the phenotype of a patient that contributes to the onset of side effects in breast cancer patients caused by conventional treatment. Chinese herbs treatment will alleviate the treatment-related side effects by altering the protein expression in the patients. Associating changes in protein levels with the onset of side effects caused by conventional treatments could be used to identify clinically relevant diagnostic biomarkers. In addition, a set of proteome that is being expressed at diseased state will exhibit the phenotype that is also correlated to the TCM syndrome differentiation. Hence, this study aims to determine the proteome profile for the syndrome differentiation of breast cancer patients treated with adjuvant Chinese herbs for musculoskeletal pain. A quasi-experimental study with purposive sampling will be conducted on 30 breast cancer patients recruited from Tung Shin hospital. All participants will be invited to complete a structured questionnaire to collect their demographic information, pain score, syndrome element differentiation, quality of life, stress, body constitution and other relevant information, including cancer type, cancer stage, and cancer treatment. The questionnaires will be self-administered either at the outpatient waiting room or in the ward of the study hospital. Blood of the patients will be collected for determination of protein expression, biochemical markers and cytokines. The study is an in-point analysis where 2 time-points of data collection and analysis will be carried out at baseline, and immediate post Chinese herbs treatment. Informed consent will be obtained before participant enrolment according to a clinical trial protocol. Statistical differences for protein expression, biochemical markers, cytokines and mean pain score before and after Chinese herbs treatment will be compared using the paired-sample t test.

Outcomes

Primary Outcomes

Feasibility of the study (Adherence)

The feasibility of the adherence will be determined by the number of sachets of Chinese herbs taken.

Time frame: Immediate post 1 week of Chinese Herbs intervention

Secondary Outcomes

Feasibility of the study (Dropout rate)

The feasibility will be assessed by dropout rate of the patients.

Time frame: Immediate post 1 week of Chinese Herbs intervention

Change in the pain score

The pain score of breast cancer patients will be assessed by Brief Pain Inventory-Short Form (BPI-SF). BPI-SF is a validated and reliable tool used to assess the severity or intensity of pain on scale ranging from 0 (no pain) to 10 (worst pain imaginable). Higher scores mean a worse outcome.

Time frame: Baseline and immediate post 1 week of Chinese Herbs intervention

Change in Syndrome element differentiation

Syndrome Element Differentiation rating scale will be used to determine the syndrome element differentiation of the patients. Syndrome Element Differentiation rating scale can quantify the syndrome elements of this patient based on the clinical manifestations. The quantitative output weight values of syndrome elements are acquired from clinical input data based on the severity and frequency of each sign and symptom. Based on the quantitative output value, the syndrome elements can then be categorized into four levels of health state or severity: normal (\<70), mild (≥ 70 to \<100), moderate (≥100 to \<150), and severe (≥ 150).

Time frame: Baseline and immediate post 1 week of Chinese Herbs intervention

Change in quality of life as assessed by WHO-BREF (World Health Organization Quality of Life)

The quality of life will be assessed by the WHO-BREF questionnaire in this study. The WHOQOL-BREF instrument comprises 26 items, measuring the following broad domains: physical health, psychological health, social relationships, and environment, with scores ranging from 0 to 100. The four domain scores denote an individual's perception of the quality of life in each domain. Domain scores are scaled in a positive direction in which higher scores denote a higher quality of life. * the minimum and maximum values: 0, 100 * higher scores mean a better outcome.
