Use of Alternative and Complementary Medicine by Colorectal Cancer Patients (ALTERNATIVCCR)

June 24, 2026 updated by: University Hospital, Limoges
Complementary and alternative medicine (CAM) is defined by the National Center for Complementary and Alternative Medicine as "a group of diverse medical and health systems, practices and products that are not currently considered part of conventional medicine" (Complementary, Alternative, or Integrative Health, n. d. 2012). Complementary medicine is used to complement conventional medicine, and alternative medicine is used instead of conventional medicine (Dy et al., 2004). These are two very different approaches, whose consequences for a cancer patient can be completely different. The use of CAM is steadily increasing in most countries. A study carried out in France in 2017 revealed that for half of CAM users, the diagnosis of cancer was one of the main factors that led patients to turn to CAM (Sarradon-Eck et al., 2017). CAM use was found to be significantly associated with younger age, female gender and higher education (Sarradon-Eck et al., 2017). The source of information about MAC was mainly friends/family and the media, while doctors and nurses played a succinct role in MAC information (Molassiotis et al., 2005). The most frequently cited reasons for using CAM were to improve their physical well-being, strengthen their bodies, improve their emotional well-being and relieve the side effects of treatment (Sarradon-Eck et al., 2020). Another study carried out in 2019 at nine centers in France showed that 45% of glioma patients had changed their eating habits after glioma diagnosis, 44% were on complementary treatment, mainly vitamins and dietary supplements, and 32% were using alternative medicine, mainly magnetism and acupuncture. A total of 68% reported using at least one of these approaches (Le Rhun et al., 2019). Another single-center study conducted in France in 2019 found that 83% of cancer patients used CAM (M et al., 2019). CAM included osteopathy, homeopathy, acupuncture, therapeutic touch, magnetism, naturopathy, cupping, Chinese medicine, reflexology and hypnosis. However, no studies have been carried out to assess the use of CAM among colorectal cancer (CRC) patients in France.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
