Plain English summary of protocol
Background and study aims
Radical radiation therapy is commonly used for the treatment of pelvic cancers. The most common acute side effect of radiation is diarrhea, which can affect up to 80% of patients treated. One of the clinical complications that occurs following an inflammatory response to irradiation is a modification of the intestinal microflora. Gastrointestinal symptoms usually begin the second week of treatment and can lead to other problems such as malnutrition, abdominal pain, fecal incontinence, tenesmus, dehydration, weakness, reduced quality of life, increased cost of care, and delayed treatment completion. The aim of this study is to find out whether partially hydrolysed guar gum (PHGG) can reduce diarrhea occurence among cancer patients undergoing pelvic radiation.
Who can participate?
Cancer patients with pelvic cancers scheduled for external beam radiotherapy (EBRT) treatment
What does the study involve?
Participants are randomly allocated to receive either 10 g PHGG twice daily or 10 g maltodextrin (placebo) twice daily. Duration of supplementation is 28 days: 14 days before radiation and 14 days during treatment. Participation involves body measurements (weight, height and mid upper arm circumference), blood pressure, temperature and heart rate measurements, collection of blood and stool samples, and symptoms charting.
What are the possible benefits and risks of participating?
Participants will know their current body measurements, vital signs, liver profile, renal profile, full blood count level and dietary intake. Information from this study will have an important bearing on health policy as guidelines for dietary treatment of pelvic radiation among cancer patients undergoing pelvic radiotherapy in the Ministry of Health. Selected participants will undergo the standard procedure similar to the current practice by the Ministry of Health. Therefore, there will be minimal risk in taking part in this study.

| Health condition(s) or problem(s) studied | Cancer patient (endometrium, cervix, colon, rectum and prostate) undergoing pelvic radiation treatment |
| Intervention | Eligible patients were allocated randomly (Random Allocation Software Ver 1.0 May 2004) to receive either 10 g twice daily PHGG or 10 g twice daily maltodextrin (placebo). Duration of supplementation was 28 days, e.g. 14 days pre radiation and 14 days during treatment. |
| Intervention type | Supplement |
| Primary outcome measure | Measured at baseline, day 7 (for microbiome growth only), day 14, day 28 and day 45: 1. Diarrhea incidence and frequency classified according to the National Cancer Institute Common Terminology Criteria (NCI-CTC); a reference of cancer patient’s managements Ministry of Health Malaysia 2017 (MOH Systemic Therapy Protocol 2016) 2. Stool formations recorded daily by patients based on Bristol Stool Charts |
| Secondary outcome measures | Measured at baseline, day 7 (for microbiome growth only), day 14, day 28 and day 45: 1. Patient's self-collected fecal samples preserved in Stool Nucleic Acid Collection and Transport Tubes (Norgen, Canada) at 4°C until further processing. Fecal DNA extracted using Stool DNA Extraction kit (Qiagen, Germany). DNA samples assessed for their quality and quantity using NanoDrop Spectrophotometer (Thermo Scientific, UK). DNA samples stored at -20°C until further use. 2. Quantification of Bifidobacterium spp. and all bacteria cells based on copy number of 16s rDNA region performed using probe-based qPCR assay by 1st Base Laboratories Sdn Bhd (604944-X). All reactions performed in a 25 μL reaction system of (Thermo Scientific™ Maxima Probe qPCR Master Mix (2X) 3. Comprehensive nutritional status assessed using Scored Patient-Generated Subjective Global Assessment (PG-SGA) 4. Quality of Life (QoL) assessed using EORTC QLQ-C30 version 3.0 questionnaire |
