Effect of a dietary supplement with antioxidant and anti-inflamatory properties on the intestinal microbiota in patients with colon cancer. Ramdonized placebo controlled clinical trial. Teratrophic study

Introduction:

The alteration in the microbiota plays a fundamental role in the promotion and progression of colon cancer due to various pathways such as inflammation and oxidative stress. The use of substances with anti-inflammatory and antioxidant effect could be useful for the treatment of this disease.

Methodology:

Prospective randomized clinical trial, with three parallel groups and double blind. Patients with stage II or III colon neoplasia who are going to receive post-surgical chemotherapy will be included. Patients will be randomized to one of the following groups: group 1 (25 patients): product with hydroxytyrosol extract; group 2 (25 patients): product with curcumin and selenium extract. Group 3 (25 patients): placebo. Before starting chemotherapy, stool and blood samples will be taken, and gastrointestinal symptoms, quality of life, symptoms of anxiety-depression and evaluation of nutritional status will be assessed. When starting chemotherapy, they will start with a daily intake of the assigned dietary supplement. At 3 months ± 2 weeks after starting chemotherapy (at least 2 weeks must have passed since the last chemotherapy of the fourth cycle), the same assessment will be made as in the initial visit, in addition to recording adherence to the intervention dietary supplement and new health problems that have appeared since the previous visit.

Patients will be randomized in a 1:1 ratio

Dietary Supplement on the Intestinal Microbiota in Patients With Colon Cancer

This diversity index is a quantitative indicator of the number of different bacteria that are present in a stool sample, taking into account the uniformity in the distribution of these bacteria in these species. Diversity index value increases both when the number of species increases and when evenness increases. The Shannon index is a well-known diversity index used in microecological studies. The higher the Shannon index value, the higher the community diversity. It is calculated as: H = -Σpi \* ln(pi), where "H" is the Shannon Diversity Index. "Σ" is a Greek symbol that means "sum". "ln" is natural log. "pi" is the proportion of the entire community made up of species i. The minimum value the Shannon diversity index can take is 0. Such a number would tell us that there is no diversity - only one species is found in that habitat. There is no upper limit to the index.

to evaluate adherence to a Mediterranean diet pattern. It consists of 14 items in which different components of the Mediterranean diet are evaluated (number of pieces of fruit consumed per day, number of portions of legumes consumed per week...). Each item is scored as 0 or 1. A total score of \<9 indicates poor adherence, while a score of ≥9 indicates good adherence.

This scale was developed by the Eastern Cooperative Oncology Group (ECOG), currently the ECOG-ACRIN Cancer Research Group. It was published in 1982. The scale describes the level of functioning of a patient in terms of her ability to take care of herself, perform daily physical activity and physical capacity (walk, work...). It was devised to use standard criteria between different centers to measure how the disease affects a patient's daily living abilities. The scale has a score from 0 to 5 in whole numbers. Lower score indicates better functional capacity. Score 0 refers to fully active patients, capable of carrying out all activities as before the onset of the disease. A score of 5 indicates the death of the patient.

The "EORTC quality of life questionnaire (QLQ)" is an integrated system to assess the quality of life of cancer patients participating in international clinical trials. The main questionnaire is the "QLQ-C30". Version 3.0 is currently the standard version. The QLQ-C30 is made up of multiple-item and single-item scales. Five functionality scales, three symptom scales, a global health status/quality of life scale, and six individual items are included. Each of the multiple item scales includes a different set of items; no item appears on more than one scale. All single-item scales and measures range in score from 0 to 100. A high scale score represents a higher level of response. Thus, a high score for a functionality scale represents a high/healthy level of functionality, a high score for global health status/quality of life represents a high quality of life, but a high score for a scale or isolated items of symptoms represents a high level of symptoms/problems.

It is a supplemental questionnaire module to be used together with the QLQ-C30. The QLQ-CR29 incorporates 4 multi-item and 19 single-item scales. A variety of common symptoms and problems are assessed in colorectal cancer patients. The scoring approach is identical in principle to that of the scales or isolated items of functionality and symptoms of the QLQ-C30. All scales and single-item measures have a score range of 0 to 100. A high score on the functionality scale and the isolated items of functionality represents a high level of functionality, while a high score for the scales and isolated items represents a high level of functionality. of symptoms represents a high level of symptomatology or problems.

Hospital Anxiety and Depression Scale (HADS). Its objective is to detect depressive and anxious disorders in non-psychiatric hospital services, avoiding overlapping with symptoms due to physical illness, without taking into account the physical aspects that may accompany anxiety/depression, focusing only on emotional ones. It is a self-administered scale with 14 items divided into 2 subscales (anxiety and depression) whose maximum score is 21 points for each of them. Based on the score obtained, patients can be classified as normal (\<7), doubtful (between 8 and 10) and potential clinical case (≥11). The score is referred to the last week.

Gastrointestinal symptoms questionnaire: an own questionnaire created for this study will be carried out in which the presence of nausea, vomiting, diarrhoea, constipation, acid reflux, early satiety, abdominal distension and abdominal pain will be evaluated. Each variable is evaluated on a scale with 4 possible responses: absent, mild, moderate, severe.
