Conditions
Summary
This prospective, single-centre, parallel-group randomised controlled trial evaluates the optimal sequencing of mammography views in women with a history of breast cancer undergoing surveillance mammography. Women treated with breast-conserving surgery within the previous five years will be randomised 1:1:1:1 to one of four mammography view sequencing groups. The primary objective is to compare patient-reported pain and satisfaction across sequencing groups. Secondary objectives include comparison of image quality (PGMI scoring), compression force, and breast thickness. A total of 400 participants will be enrolled at Beaumont Hospital Breast Care Centre over 2.5 years.
Eligibility
Inclusion Criteria1
- Female patients aged 18 years or older History of breast cancer treated with breast-conserving surgery (wide local excision) Undergoing first annual surveillance mammogram following completion of surgery and radiotherapy Within five years of breast cancer treatment May have history of whole-breast or partial-breast radiotherapy May have history of axillary surgery Able and willing to provide informed consent
Exclusion Criteria1
- Male patients Patients younger than 18 years History of mastectomy History of bilateral wide local excision Lack of capacity to provide informed consent More than five years since completion of breast cancer treatment
Interventions
Standard surveillance mammography consisting of MLO and CC views of both treated and untreated breasts. Participants are randomised to one of four predefined sequences determining the order in which views are obtained. No additional imaging beyond standard of care is performed.
