MRI Screening Versus SYMptom-directed Surveillance for Brain Metastases Among Patients With Triple Negative or HER2+ MBC

Official Title

Routine MRI Screening Versus Symptom-directed Surveillance for Brain Metastases Among Patients With Triple Negative and HER2+ Metastatic Breast Cancer (MBC): A Single-centre Randomized Pilot Study

Summary:

In this study, 50 women with either HER2+ or triple negative metastatic breast cancer but no known brain metastases will be recruited at the Sunnybrook Odette Cancer Centre. They will be randomized to undergo either routine MRI screening of their brain every 4 months for 1 year or standard-of-care (MRI only if symptoms of brain metastases develop). Patients will complete questionnaires about quality of life and cancer-related anxiety throughout the study. To determine why some cancers spread to the brain and others do not, blood samples will be collected to analyze the genetic makeup of patients' breast cancers. Finally, a novel MRI imaging technique that detects abnormal metabolism in the brain will be used to help detect brain metastases even earlier than the standard MRI. If results are promising, we will conduct a large multi-centre randomized trial to determine whether screening for brain metastases can help them live longer with improved quality of life.

Trial Description

Primary Outcome:

  • Proportion of eligible patients at the Sunnybrook Odette Cancer Centre (SOCC) who i) agree to enroll in the proposed randomized phase II pilot study, and ii) complete the study protocol.
Secondary Outcome:
  • Proportion of patients in the control arm who undergo imaging of the brain with CT or MRI.
  • Incidence of symptomatic brain metastases.
  • Number of interventions used to treat brain metastases.
  • Size and location of BrM per patient.
  • Neurologic-specific quality-of-life (The Functional Assessment of Cancer Therapy-Brain; FACT-BR version 4 tool).
  • Overall quality-of-life (EORTC core quality of life questionnaire; EORTC QLQ-C30 version 3 tool).
  • Cancer-related anxiety (NCI PRO-CTCAE for anxiety).
  • Time to death due to any cause.
  • Time to death due to neurologic progression.
