Antioxidant Supplements, Genetics and Chemotherapy Outcomes

August 4, 2022 updated by: Roswell Park Cancer Institute
This study will investigate the null hypothesis that use of antioxidant supplements during adjuvant chemotherapy will have no impact on toxicities and disease-free, as well as overall, survival, and also evaluate the role of polymorphisms in genes related to oxidative stress in relation to treatment outcomes.

Study Overview

Indicates the current recruitment status or the expanded access 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.

Detailed Description

This study will enroll 3000 women from S0221with node positive or high-risk node-negative breast cancer receiving AC+T onto this ancillary study to address the following specific aims:

  1. To characterize use of antioxidant supplements with a survey instrument prior to and at completion of treatment, and to evaluate reported use pre and post treatment in relation to toxicity and disease-free survival. The potential effects of diet, physical activity, and other lifestyle factors on relationships between supplement use and treatment outcomes will also be considered.
  2. To evaluate if variants (polymorphisms) in genes that produce reactive oxygen species (ROS) (MPO) and in genes that protect cells from the effects of ROS are associated with treatment-related toxicities and with disease-free survival.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

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
Epidemiologic Questionnaire
Time Frame: At baseline interview
Self administered questionnaire to evaluate use of antioxidant supplements in relation to toxicity
At baseline interview
Evaluate if variants in genes are associate with treatment related toxicities

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 18, 2004

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
