Eligibility Criteria Expand/Collapse

Step 1 Pre-Randomization - Patients must have a diagnosis of hormone receptor positive (ER+ and/or PR+), HER-2 negative, metastatic (M1) breast cancer and must be receiving or plan to receive first-line systemic treatment for metastatic disease; patients must be registered to Step 1 between 14 days prior to and 28 days after start of first-line systemic treatment for metastatic disease; patients (women and men) must be >/= 18 years of age; patients must have been tested for all of the following breast cancer specific STMs after diagnosis of metastatic disease and within +/-14 days of initiation of first-line systemic treatment for metastatic disease: CA 15-3, CA 27.29, CEA; at least one of these STMs must have been >/= 2 x the institutional upper limit of normal at this time. Patients must have systemic radiographic imaging prior to initiation of systemic therapy for treatment of metastatic breast cancer and prior to Step 1 registration with either a computed tomography (CT) scan of the chest and abdomen with or without CT pelvis, and with or without bone scan or a positron emission tomography (PET) scan with or without CT; Patients must be willing to obtain disease monitoring (imaging and/or serum tumor markers) at their current center for the duration of the study intervention (312 weeks after Step 2 randomization); patients with known cirrhosis, untreated B12 deficiency, thalassemia, or sickle cell anemia are not eligible as these could cause falsely elevated STM levels; patients with known brain metastases are not eligible as they may require regular radiographic monitoring to assess treatment response; patients must not be currently enrolled or plan to participate in a first-line treatment trial for metastatic breast cancer with a defined monitoring schedule; patients who are able to complete questionnaires in English or Spanish must participate in patient-reported outcome (PRO) assessments as outlined in the protocol; patients must not be pregnant due to the potential harm to the fetus from radiation exposure from radiographic imaging. Patients must not have received prior systemic therapy for metastatic breast cancer, except for their current treatment regimen initiated no more than 28 days prior to registration. Step 2 Randomization - Patients must be tested for all 3 breast cancer specific STMs (CA 15-3, CA 27.29, CEA) between 56 and 112 days after initiation of first-line systemic therapy for metastatic disease and at least one of the STMs that was previously elevated must have decreased from the assessment at Step 1 by >/= 25% at this time. Patients must not have known progression since registration to Step 1. Patients must be registered to Step 2 randomization between 56 days and 112 days after the initiation of first-line systemic therapy for metastatic disease. Patients must have been eligible for Step 1 in order to be eligible for Step 2 Randomization. Baseline questionnaires must be completed within 28 days prior to Step 2 randomization. (Note: Those patients who cannot complete the PRO questionnaires in English or Spanish can be registered to Step 2 without contributing to PRO research)
