Study population: The study population will include women residing in Norway, who are currently alive and were invited and attended, and were invited but did not attend the screening program. Among the attending and not attending women, women who were diagnosed with breast cancer 2006-2017 will be randomly selected. The women diagnosed with breast cancer will be stratified by detection mode (screen-detected versus symptomatic breast cancer). The women within each group will be matched by age. Additionally, women who have never had a diagnosis of breast cancer will be randomly selected from the target population of BreastScreen Norway.
Who may be able to join
- Screened in BreastScreen Norway and diagnosed with breast cancer between 2006 and 2017
- Diagnosed with symptomatic breast cancer between 2006 and 2017 and never attended screening

About this study
Official title: Long-term Effects Following Treatment of Women With Screen-detected Versus Symptomatic Breast Cancer
The objective of this project is to generate evidence about quality of life related to side effects of treatment of women with screen-detected versus symptomatic breast cancer. The project will investigate the impact of detection mode (by screening or by symptoms) versus tumor characteristics as a predictor of quality of life among breast cancer survivors. The burden of long-term effects, measured as quality of life at specific points after diagnosis, will be compared between these groups. The results will also be compared with a control group of women, who have attended screening, but never been diagnosed with breast cancer.
Read the detailed description
The project will include a retrospective information which will be collected by using a self-administered questionnaire about the treatment women received and their quality of life at certain time points after a breast cancer diagnosis. Women aged 50-69 years at the time of diagnosis are the target group of BreastScreen Norway and also for this project.
The women will be identified from the Cancer Registry databases. The questionnaire will be based on EQ-5D-5L and will be developed in close collaboration with breast cancer survivors who have personally experienced the long-term effects of breast cancer treatment, whether resulting from screen-detected or symptomatic breast cancer.
The questionnaire will cover topics related to demographics, treatment, and information required to estimate health related quality of life (HRQoL) and quality-adjusted life years (QALY). Information about detection mode and disease stage at diagnosis will be extracted from the Cancer Registry.
Study I - a review of the literature in a paper describing and analyzing the current evidence on quality of life among women diagnosed with breast cancer and treated for this disease, with a focus on disease stage at diagnosis. Due to substantial changes in treatment during the last decades, only studies reporting on women who have received treatment in 1995 or later will be included. Solely studies written in English will be included.
For studies II and III, data collected from the self-administered questionnaire will be used. In addition, information about screening history and tumor characteristics will be obtained from the Cancer Registry of Norway.
In Study II, quality of life will be compared between about 1000 women treated for screen-detected, about 1000 women treated for symptomatic, about 1000 women treated for interval cancer and about 1000 women without any diagnosis of breast cancer. The main hypothesis is that women with screen-detected breast cancer have a higher quality of life than women diagnosed with symptomatic breast cancer.
Study III will be a continuation of Study II, and will aim to investigate the impact of detection mode versus tumor characteristics and treatment types as the main predictor of long-term quality of life among women diagnosed and treated for breast cancer among the two groups of women, those diagnosed with screen-detected breast cancer versus those diagnosed with interval breast and symptomatic breast cancer.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Study II | * Women with a screen-detected breast cancer after attending BreastScreen Norway * Women with symptomatic breast cancer, who have never been screened in BreastScreen Norway * Women with interval breast cancer after attending BreastScreen Norway * Women free from breast cancer | |

What is being measured
The primary outcome is the main question the study is designed to answer.
Quality of life score
Quality of life measure from 0 to 100 on a visual analogue scale
Measured: 2006-2017
QALY (Quality-Adjusted-Life-Year)
QALY is calculated by estimating the years of life remaining for a woman following a particular treatment or intervention and weighting each year with her corresponding health related quality of life score
Measured: 2006-2017

Questions about this trial
What is this clinical trial studying?
An observational study of Breast Cancer, run by Norwegian Institute of Public Health at 1 site in Norway.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quality of life score (time frame: 2006-2017). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03877029, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Mar 2026; AzTrials last refreshed its copy on 7 Nov 2026.
