This randomized research trial studies how well serum tumor marker directed disease monitoring works in monitoring patients with hormone receptor positive Her2 negative breast cancer that has spread to other places in the body. Using markers to prompt when scans should be ordered may be as good as the usual approach to monitoring disease.
PRIMARY OBJECTIVES: I. To assess whether patients with HER-2 negative, hormone receptor positive, metastatic breast cancer who are monitored with serum tumor marker directed disease monitoring (STMDDM) have non-inferior overall survival compared to patients monitored with usual care. SECONDARY OBJECTIVES: I. To compare cumulative direct healthcare costs through 48 weeks among patients monitored with STMDDM versus those monitored with usual care in this patient population. II. To assess whether the patient-reported outcomes (PROs) of anxiety and quality of life (QOL) are different among pat…
Inclusion Criteria: * STEP 1 REGISTRATION * Patients must have a diagnosis of hormone receptor positive (estrogen receptor positive \[ER+\] and/or progesterone receptor positive \[PR+\]), HER-2 negative, metastatic (M1) breast cancer and must be receiving or plan to receive first-line systemic treatment for metastatic disease. (Systemic treatment is any treatment meant to treat the whole body such as endocrine therapy +/- targeted therapy +/- chemotherapy). * NOTE: Participants are eligible if they have either de-novo metastatic breast cancer and/or recurrent breast cancer from an earlier…
Imaging and serum tumor markers are at the discretion of the treating physician (however imaging must be performed at least every 12 weeks).
Serum tumor markers every 4-8 weeks without imaging
