Longitudinal Tumor Burden Quantification Using Circulating Tumor DNA in Metastatic Lobular Breast Cancer
Recruiting now
Conditions studied: Metastatic Invasive Lobular Carcinoma (mILC)
In brief
The goal of this study is to characterize early dynamic changes in ctDNA, which can aid in tailoring early therapy in patients with metastatic Invasive lobular carcinoma (ILC). Response assessment using ctDNA analysis could not only aid in de-escalation but also escalation strategies.

You may qualify if…
- Signed informed consent
- Patients must have histologically or cytologically confirmed invasive lobular breast cancer that is ER+ (> 1% staining) and HER2-negative as per ASCO/CAP guidelines with radiographical or clinical evidence of metastatic disease
- Lobular histology as assessed on either tissue collected from a metastatic lesion or from the patient's primary breast tumor (in case of recurrent metastatic disease)
- Patients with mixed ductal/lobular (NST/ILC) tumors are eligible to participate (with the ultimate goal to evaluate 20 patients with pure ILC)
- Patients must have tumor tissue available for whole exome sequencing for Signatera assay design
- Prior therapies:
- Patients must not have received any therapy in the metastatic setting
- Patients could have received adjuvant therapy as indicated for their primary breast cancer
- Age ≥ 18 years
- Patients may be pre- or post-menopausal.
You may not qualify if…
- Stage I-III breast cancer
- Lack of lobular histology on tumor tissue biopsy
- Other active cancer (previously treated cancer with no current evidence of disease is allowed)
- ctDNA assay development is unattainable due to insufficient tumor tissue or sequencing failure
Where it is running
- Magee Women's Hospital of UPMC — Pittsburgh, Pennsylvania, United States (enrolling)
