Brief Summary

This phase II trial studies how well FDG-PET/CT works in assessing the response of patients with breast cancer that has spread to the bones or mostly to the bones (bone-dominant metastatic breast cancer). Diagnostic procedures, such as FDG-PET/CT, may work better in measuring breast cancer activity before and after treatment compared to other standard imaging tests.

Detailed Description

PRIMARY OBJECTIVE:

I. Evaluate the performance of fludeoxyglucose F-18 (FDG)-positron emission tomography (PET)/computed tomography (CT) response criteria (modified PET Response Criteria in Solid Tumors \[PERCIST\] complete, partial and stable metabolic disease versus progressive metabolic disease) as a binary predictor of progression-free survival (PFS) in patients with bone-dominant (BD) metastatic breast cancer (MBC) treated with systemic therapy.

SECONDARY OBJECTIVES:

I. Evaluate the ability of FDG-PET/CT modified PERCIST criteria (complete versus \[vs\] partial vs stable vs metabolic progression) to independently predict PFS in patients with BD MBC.

II. Evaluate the ability of FDG-PET/CT modified PERCIST criteria (complete, partial, and stable versus progressive metabolic disease) to predict time to skeletal related events (SRE) and overall survival (OS) in patients with BD MBC.

III. Evaluate the ability of FDG-PET/CT metrics (percent change in peak standardized uptake value corrected for lean body mass (SULpeak), maximum standardized uptake value corrected for body weight (SUVmax) as continuous variables in index or up to 5 lesions) to predict PFS, time to SRE and OS in patients with BD MBC.

IV. Assess the utility of FDG-PET/CT to identify disease progression by identification of new lesions not identified by standard CT and bone scan.

EXPLORATORY OBJECTIVES:

I. Define criteria for selection of FDG-avid bone lesions for analysis based on thresholds for SULpeak or SUVmax.

II. In collaboration with National Cancer Institute (NCI) Quantitative Imaging Network (QIN), explore alternative methods for measuring metabolic response with FDG-PET/CT (e.g., total lesion glycolysis, quantitative total bone imaging, MD Anderson bone criteria, and radiomics) to predict clinical endpoints in patients with BD MBC.

III. Evaluate automated image analysis of FDG-PET/CT by AutoPERCIST.

OUTLINE:

Patients receive FDG intravenously (IV) and undergo PET/CT scan over 15-30 minutes at baseline (within 21 days before start of standard systemic treatment) and at 12 weeks after start of standard systemic treatment in the absence of unacceptable toxicity.

After completion of study, patients are followed up periodically for up to 3 years after study registration.

  • Patients must have radiologically confirmed bone-dominant (BD) or bone-only (BO) disease

    • BD defined as disease involving bone with or without limited measurable metastases by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, with >= 1 non-irradiated bone metastasis on bone scintigraphy

      • NOTE: Limited measurable metastases includes lymph nodes and the soft tissue components of lytic or mixed lytic/blastic bone metastases. Any number of lymph nodes < 3 cm and up to 2 lymph nodes > 3 cm will be allowed. Up to 5 measurable soft tissue components of lytic or mixed mytic/blastic bone metastases will be allowed
    • BO defined as detectable disease confined within the bone (any site, any number of lesions). Diagnosis requires abnormalities identified by imaging (bone scan, CT +/- PET +/- magnetic resonance imaging [MRI]) with no other sites of metastases identified and with >= 1 non-irradiated bone metastasis on bone scintigraphy

  • Patients must have no contraindication to FDG-PET imaging

  • Patients must have one of the following systemic therapies:

    • Plan to receive either 1st or 2nd line endocrine therapy for metastatic breast cancer. Endocrine therapy may include selective estrogen receptor modulators (SERMs), aromatase inhibitors, and/or fulvestrant that may be combined with Food and Drug Administration (FDA)-approved biologic agents (palbociclib, ribociclib, abemaciclib, everolimus, alpelisib)
    • Chemotherapy per National Comprehensive Cancer Network (NCCN) or institutional standard. Use of colony stimulating growth factor must be suspended for >= 14 days prior to FDG-PET/CT scans at baseline and 12-weeks
    • Plan to receive HER2-targeted therapy per ASCO, NCCN, and/or institutional guidelines as indicated for patients with HER2 positive disease. When HER2-targeted therapy is used with chemotherapy, use of colony stimulating growth factors is NOT expected or should be suspended for a minimum of 2 weeks, but preferably for at least 3 weeks prior to the required FDG-PET/CT scan time points
  • The use of bone-stabilizing agents (bisphosphonates or denosumab) is permitted

  • Patient must meet institutional guidelines for renal function for MRI and CT scanning

  • Patient's life expectancy must be estimated at >= 24 weeks

  • The patient is participating in the trial at an institution which has agreed to perform the imaging research studies, completed the ECOG-American College of Radiology Imaging Network (ACRIN) defined PET/CT scanner qualification procedures and received ECOG-ACRIN PET/CT scanner approval

  • Patients must complete the baseline (T0) FDG-PET within 28 days prior to registration or within 28 days after registration

    • For patients completing the baseline (T0) FDG-PET AFTER registration all parameters must be met

    • For patients who completed the baseline (T0) FDG-PET prior to registration the following tests are exempt:

      • Pregnancy testing documentation prior to FDG-PET (T0 time point)
Exclusion Criteria
  • Patients with RECIST 1.1 measurable lesions in viscera, active central nervous system (CNS), leptomeningeal carcinomatous or pleural or peritoneal disease will not be eligible. Patients with prior CNS metastases treated with radiation or resection and without evidence of clinical or radiographic progression within 28 days of registration are eligible
  • Patients who have received greater than 3 lines of cytotoxic chemotherapy for metastatic breast cancer are not eligible
  • Patients currently participating in or have participated in a study of an investigational agent or using an investigational device within 3 weeks of study registration are not eligible
  • Patients with known additional malignancy that is progressing or requires active treatment are not eligible. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy
  • Women must not be pregnant because FDG is a radiopharmaceutical with the potential for teratogenic effects and PET/CT involves additional radiation exposure. In addition, because of radiation exposure to a nursing infant from FDG, women who are breastfeeding are also excluded from this study. All females of childbearing potential must have a blood test or urine study within 7 days prior to FDG-PET/CT to rule out pregnancy. Patients are excluded from this if baseline FDG-PET/CT scan met study parameters and was completed within 28 days of study registration

Primary Outcome Measures
NameTimeMethod
Performance of fludeoxyglucose F-18 (FDG)-positron emission tomography (PET)/computed tomography (CT) response criteria as a binary predictor of progression-free survival (PFS)Up to 3 years after study registration

Will evaluate the performance of FDG-PET/CT response criteria (modified PET Response Criteria in Solid Tumors complete, partial and stable metabolic disease versus progressive metabolic disease) as a binary predictor of PFS in patients with bone-dominant (BD) metastatic breast cancer (MBC) treated with systemic therapy.

Secondary Outcome Measures
NameTimeMethod
Utility of FDG-PET/CT to identify disease progression by identification of new lesions not identified by standard CT and bone scanUp to 3 years after study registration

For the cases where progression is documented in the study, will record and tabulate the number of new lesions uniquely identified by the 12-week FDG-PET/CT research scan.

Ability of FDG-PET/CT metrics to predict time to SRE in patients with BD MBCUp to 3 years after study registration

For each participant, will collect up to 5 lesions from FDG-PET/CT scans and calculate the percent change in SULpeak, SUVmax from T0 to T1 scans. Multivariable Cox proportional hazard models will be used to model the ability of these changes to predict time to SRE. The analysis will first be conducted on the index lesion (i.e., associating the change of SUVpeak or SUVmax for the index lesion with outcomes), and then be applied to the average change of up to 5 lesions (i.e., associating the average change of SUVpeak or SUVmax from all detected lesions with outcomes). The C-statistics will be used to measure the performance.

Ability of FDG-PET/CT metrics to predict OS in patients with BD MBCUp to 3 years after study registration

For each participant, will collect up to 5 lesions from FDG-PET/CT scans and calculate the percent change in SULpeak, SUVmax from T0 to T1 scans. Multivariable Cox proportional hazard models will be used to model the ability of these changes to predict OS. The analysis will first be conducted on the index lesion (i.e., associating the change of SUVpeak or SUVmax for the index lesion with outcomes), and then be applied to the average change of up to 5 lesions (i.e., associating the average change of SUVpeak or SUVmax from all detected lesions with outcomes). The C-statistics will be used to measure the performance.

Ability of FDG-PET/CT modified PERCIST criteria (complete versus [vs] partial vs stable vs metabolic progression) to independently predict PFS in patients with BD MBCUp to 3 years after study registration

Will keep the multiple categories of FDG-PET/CT modified PERCIST criteria and test the PFS differences across them using the Kaplan-Meier survival curve and the corresponding log-rank test. The multivariable Cox proportional hazard model will be also fitted with the adjustment of the same set of confounders (e.g., age, line of therapy - early line treatment versus late line treatment, type of therapy - endocrine therapy versus chemotherapy). Since the categories of FDG-PET/CT modified PERCIST criteria are ordered, will also apply the method of C-statistics to evaluate the performance after quantifying the criteria (i.e., 1-complete response, 2-partial response, 3-stable, 4-metabolic progression).
