ClinicalTrials.gov · September 11, 2026

Preliminary Why this matters to you Expert discussion

Early or partial results. Treat as a signal, not a conclusion.

AI Summary

This is a clinical trial registry record for an active observational study with no posted results. The study aims to characterize knowledge of environmental exposures and investigate potential links between weight and hormone-disrupting chemicals in breast cancer survivors and family members.

What was studied

Observational. Breast Cancer; age from 18 Years; accepts healthy volunteers. Intervention: Pre-Focus Group Survey; Focus Group Session; Post-Focus Group Survey. n = 30. 1 site: United States.

Key findings

Safety

This is a registry record only; no efficacy, safety, or outcome results are reported.

Who this may help

The source did not state who this applies to in practice.

Plain-language summary

This is a registry record for an observational study that is actively recruiting with no results posted; it describes planned data collection via surveys and video in breast cancer survivors and family members.

Caveats

This is a registry record only; no efficacy, safety, or outcome results are reported.
Study is in active recruitment; data collection and analysis not yet complete.
Sample size is small (n=30 estimated) and observational without a comparator group.
Primary outcomes focus on knowledge and interest, not clinical endpoints or causal mechanistic evidence.

Evidence assessment

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

Study design

limited

Observational design with surveys and video; no control arm or randomization.

Directness

limited

Knowledge and interest outcomes are measured; causal link between weight and chemical exposure not yet tested.

Consistency

insufficient

No results reported; no comparator data available.

Risk of bias

insufficient

Observational, recruiting study; no methods details on blinding, allocation, or analysis plan.

Sample adequacy

limited

Estimated 30 participants for exploratory aims on knowledge and environmental exposure links.

What is missing. This record has no key findings. That is a gap in the analysis, not a judgement about the study.

Source abstract

Registry record from ClinicalTrials.gov (NCT07137468). This is a study registration, not published results. Lead sponsor: M.D. Anderson Cancer Center. Recruitment status: RECRUITING. Study type: OBSERVATIONAL. Enrollment: 30 participants (ESTIMATED). Conditions: Breast Cancer. Interventions: OTHER: Surveys; OTHER: Video. Primary outcome measures: Outcome Measure , Through study completion; an average of 1 year. Brief summary: To learn about breast cancer survivors' and their family members' knowledge of and interest in learning about environmental exposures related to personal care products. Researchers also want to learn if there is a link between excessive weight and chemicals that may affect hormones.
