Dietary Supplements Among Cancer Patients: Tolerance, Impact on Medications, and Potential Drug Interactions (Dietary Supple)

June 19, 2026 updated by: Sihame Lkhoyaali, Centre Mohammed VI de la Recherche et de l'Innovation (CM6RI)

Use of Dietary Supplements Among Cancer Patients: Tolerance and Impact on Medications and Drug Interactions Assessed Using the Hedrine Software

The goal of this observational study is to To assess the prevalence and patterns of dietary supplement use among patients with cancer and to analyze the impact of these supplements in the context of anticancer medical treatments, including chemotherapy, targeted therapies, hormone therapy, and immunotherapies.

The main questions it aims to answer :

  • What is the prevalence of dietary supplement use among cancer patients, and what is their tolerance profile?
  • Are there any potential drug interactions between dietary supplements and anticancer medications?

Participants will:

  • Provide sociodemographic information, including age, sex, educational level, and other relevant characteristics.
  • Report their use of dietary supplements, including the types of supplements consumed (e.g., vitamins, minerals, herbal products), dietary practices, frequency and duration of use, and reasons for consumption (e.g., medical recommendation or self-medication).
  • Report any perceived adverse effects related to dietary supplement use to assess tolerance.
  • Allow the collection of relevant clinical data from their medical records, including cancer type, ongoing anticancer treatments, and treatment-related adverse effects.

Study Overview

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

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

Sampling Method

Non-Probability Sample

Study Population

Adult patients diagnosed with cancer and receiving medical anticancer treatment (chemotherapy, hormone therapy, immunotherapy, or targeted therapy) at the study site. Participants will be assessed for dietary supplement use, tolerance, and potential interactions between dietary supplements and anticancer medications.

Description

Inclusion Criteria:

  • Patients diagnosed with cancer and receiving medical anticancer treatment, including chemotherapy, hormone therapy, immunotherapy, and targeted therapies.
  • Current or recent use of one or more dietary supplements (e.g., vitamins, minerals, herbal products, or other nutritional supplements).
  • Adult patients : >=18

Exclusion Criteria:

  • Patients unable to complete the study questionnaire because of cognitive impairment or a deteriorated health condition.
  • Failure or refusal to provide written informed consent.

What is the study measuring?

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.
Outcome Measure
Measure Description
Time Frame
Prevalence of Dietary Supplement Use and Tolerance
Time Frame: At enrollment
Assessment of the prevalence of dietary supplement use among cancer patients and evaluation of adverse effects associated with dietary supplement consumption.
At enrollment
Potential Drug-Supplement Interactions
Time Frame: At enrollment or single study visit
Assessment of potential interactions between dietary supplements and anticancer medications
At enrollment or single study visit

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
