Plain English summary of protocol
Background and study aims
Breast cancer is the most common cancer in women. Routinely women who are diagnosed with breast cancer will be followed with a yearly mammogram (an X-ray test) for a minimum of 5 years. There is a little evidence that routine mammogram follow-up of patients treated for early breast cancer helps to detect recurrences or new cancers. The aim of this study is to follow up patients with early breast cancer for recurrences and new primary cancers in order to determine the role of mammogram follow up.
Who can participate?
Patients who were diagnosed with breast cancer either by screening or presented with symptoms from 2001 to 2006.
What does the study involve?
This is an observational study that follows up patients who had breast cancer from 2001 to 2006 for a minimum of 10 years or until recurrence of cancer to find out whether this recurrence was detected by follow-up mammogram.
What are the possible benefits and risks of participating?
There are no expected benefits or risks for participants
Where is the study run from?
Addenbrooke’s Hospital (UK)
When is the study starting and how long is it expected to run for?
October 2015 to January 2016

| Scientific title | The effectiveness of mammography surveillance after treatment of primary breast cancer: a single-centre retrospective cohort study |
| Study acronym | MaSATPriBrCa |
| Study objectives | Is mammography surveillance after treatment of primary breast cancer efficient at detecting recurrence and new primaries? |
| Ethics approval(s) | Access to patients’ data was obtained through an official data request to Addenbrooke’s Hospital Research Department. Formal ethics committee clearance was not needed as this was a service evaluation. |
| Health condition(s) or problem(s) studied | New breast cancer/recurrence in patients with primary breast cancer after treatment |
| Intervention | Patients who had primary breast cancer during the years 2001 to 2006 were included and followed up for a minimum of 10 years. Patients who developed recurrence/new primaries are studied to find if that incident was picked up by a mammogram. All data are collected from the hospital database. |
| Intervention type | Other |
| Primary outcome measure | Effectiveness of follow-up mammography at detecting recurrences/new cancers, measured using the hospital database with a minimum of 10 years of follow-up |
| Secondary outcome measures | The rate of detection of recurrence/new primaries by mammogram between patients whose original tumour was detected by screening and those who presented symptomatically, measured using the hospital database with a minimum of 10 years of follow-up |
