Evaluating the De-Escalation of Surveillance for Patients Who Have Undergone Curative Treatment for Primary Breast Cancer (De-Escalation)

May 29, 2026 updated by: Royal College of Surgeons, Ireland

Breast cancer is the most common cancer in women around the world. That means a lot of women are affected by it every year, and it's important that we always look for ways to improve their care, not just during treatment, but afterwards too. After treatment for early-stage breast cancer, patients usually come back to the hospital for regular check-ups for up to five years. These visits are based on old guidelines, and even though breast cancer treatment has improved a lot over the years, the follow-up schedule has stayed the same. This study is being done to see if we can safely reduce the number of hospital visits after treatment, while still keeping patients healthy and well looked after.

Right now, patients are asked to attend follow-up appointments at 6, 12, 18, 24, 36, 48 and 60 months (that's every 6 to 12 months for five years). These clinic visits often involve long waits and can cause stress or anxiety. At the same time, patients are also invited for a mammogram once a year. Recent research shows that most recurrences of breast cancer are found by patients themselves or during their annual mammograms, not necessarily at these clinic visits. That's why we're looking at whether we can safely reduce the number of hospital appointments, without affecting patient safety.

In this study, some patients will continue with the usual five-year clinic schedule. Others will only attend hospital clinics for the first two years (at 6, 12, 18 and 24 months), and after that, they will no longer need to come in for the extra follow-up visits, but they will still have their annual mammograms as normal.

Within this study all participants will complete a short questionnaire once a year. This will help us understand how the different follow-up plans affect quality of life, and how patients feel about their care. This research study is taking place to find out if fewer hospital check-ups, combined with continued mammogram screening, is just as safe and possibly better for patients' wellbeing.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study began in 2025 at the Breast Centre in Beaumont RCSI Cancer Centre. We expect that around 600 people will take part. If you agree to join the study, you will be placed into one of two groups:

  • One group will continue with the usual follow-up plan after breast cancer treatment. This includes regular hospital visits for up to five years.
  • The other group will follow a new plan, where hospital visits will stop after two years, but yearly mammograms will continue as normal.
  • Participants will continue to have access to the breast care team by the usual contact points such as your breast care nurse. All patients following treatment of breast cancer in Beaumont hospital are provided with a direct phone number to contact the breast care nurse should they have any concern.

Participants won't need to take any new medicines or treatments. Each year, we'll ask you to complete a short questionnaire (either in person or over the phone) to tell us how participants are feeling and how the follow-up process is working for them.

This will help the researchers understand whether the new follow-up plan is just as safe and possibly more convenient for patients.

Participants will be placed into one of two groups, this will be chosen at random (like flipping a coin). Both groups will be followed for a total of five years after their breast cancer treatment.

Group 1 - Current Follow-Up Plan (Usual Care):

  • Continue with the current schedule of hospital clinic visits at: 6, 12, 18, 24, 36, 48 and 60 months after your treatment
  • Be invited for your annual mammogram as normal
  • Be asked to fill in a short questionnaire at your clinic visits at 24, 36, 48, and 60 months. This will help us understand how you're feeling and your experience with follow-up care
  • All your appointments will take place in person at the Breast Centre in Beaumont Hospital.

Group 2 - New Follow-Up Plan (Study Group):

  • Attend clinic visits at: 6, 12, 18, and 24 months after treatment
  • Be discharged from hospital clinics after 2 years
  • Continue to have your annual mammogram as normal
  • Fill in the same questionnaire at 24 months in person, and then by telephone at 36, 48 and 60 months
  • If you are in this group and ever feel you would prefer to return to hospital clinic visits, you will be supported to do so.

No extra hospital visits, medical tests, or blood samples are required for this study. The questionnaire may ask about your health, daily activities, and how you feel about the follow-up care you are receiving. Some people may find questions about quality of life or cancer follow-up a little emotional or upsetting, but you can skip any question you don't want to answer. Researchers may look at medical records to check information about diagnosis, treatment, and follow-up care. This will be done confidentially, and only by members of the research team who are trained to handle personal health information safely.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Health-Related Quality of Life Measured by the EuroQol 5-Dimension 5-Level Questionnaire (EQ-5D-5L)
Time Frame: Measured at months 24, 36, 48 and 60 post randomisation.
Health-related quality of life measured using the EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L). The EQ-5D-5L evaluates five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each scored on five response levels. Responses will be converted to an EQ-5D-5L index score using validated scoring methods. Higher index scores indicate better health-related quality of life.
Measured at months 24, 36, 48 and 60 post randomisation.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Breast Cancer Recurrence During Follow-Up
Time Frame: Measured with annual mammogram and clinical outcomes at months 12, 24, 36, 48 and 60 post randomisation.
Number of participants with breast cancer recurrence identified during follow-up through annual mammography, clinical assessment, patient-reported symptoms, or medical record review.
Measured with annual mammogram and clinical outcomes at months 12, 24, 36, 48 and 60 post randomisation.
