September 8, 2025 updated by: Yeon Hee Park, Samsung Medical Center

A Prospective Cohort Study Comparing Metabolic Response Evaluation by F-18 FDG PET-CT Versus Conventional Imaging for Outcome Stratification in Patients With Advanced Breast Cancer Receiving First-line Systemic Therapy

This study is a prospective cohort study comparing metabolic response evaluation by F-18 FDG PET-CT versus conventional imaging for outcome stratification in patients with advanced breast cancer receiving first-line systemic therapy.

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

PET-CT, CE-CT ± bone scan are performed before and during treatment (6, 12, 24, 48 weeks) of the first systemic treatment in a total of 100 patients with advanced breast cancer, and some patients analyze ctDNA-based MRD by collecting blood at the same time point. We analyze the relationship between patient-specific responses and PFS, and compare the predictive performance of imaging and molecular indicators.

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

Histologically confirmed metastatic or locally advanced breast cancer patients with no radical topical treatment

Description

Inclusion Criteria:

  1. 19 years of age or older
  2. histologically confirmed metastatic or locally advanced breast cancer with no radical topical treatment available
  3. If there is liver metastasis, which the researcher believes will be difficult to evaluate the response accurately with bone metastasis or CT
  4. May or may not have measurable lesions in accordance with RECIST 1.1 criteria
  5. Patients who meet the criteria for coverage of F-18 FDG PET-CT tests conducted for the purpose of evaluating treatment response according to the Health Insurance Review and Assessment Service's announcement
  6. Patients scheduled to start primary systemic therapy for advanced breast cancer (endocrine therapy, targeted therapy, chemotherapy, immunotherapy or their combination therapy)
  7. Patients willing to undergo continuous response assessments using F-18 FDG PET-CT and CE-CT (± bone scan if clinically necessary) at the time point specified in the study plan (before treatment, 6, 12, 24, 48 weeks after treatment) and willing to pay for the examination accordingly
  8. ECOG Performance Status 0-2

Exclusion Criteria:

  1. a patient who has previously received systemic treatment for advanced breast cancer
  2. Taboos for F-18 FDG PET-CT (e.g., uncontrolled diabetes) or intravenous contrast agents for CE-CT (e.g., severe allergies, severe renal dysfunction)
  3. Pregnancy or lactation
  4. At the same time, other primary malignancies (except when treatment has been completed for radical purposes) are known
  5. Other medical conditions that, at the discretion of the researcher, may hinder participation in the study or affect the interpretation of the results
  6. If you are unable to follow a research procedure or follow-up

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
Time Frame
Follow up the response for 48 weeks after the start of the first systemic treatment
Time Frame: Within 4 weeks prior to the start of primary systemic treatment
Within 4 weeks prior to the start of primary systemic treatment

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.
July 25, 2025

Primary Completion (Estimated)

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 (Estimated)

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.
