About this study

A cross sectional study to determine the prevalence of persistent pain after reconstructive surgery after mastectomy for breast cancer, with a comparative analysis of a cohort treated with mastectomy without reconstruction.

Read the detailed description

The aim of the study is to determine if reconstruction of the breast after mastectomy increases the risk of reporting persistent pain 2-3 years after surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ReconstructionProcedure or surgery

    Reconstructive surgery after mastectomy, either by expander or autologous tissue. Includes both primary and secondary reconstruction

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The risk of developing persistent if reconstructed

    The risk of developing persistent if reconstructed compared to patients mastectomized without reconstruction expressed as an odds ratio.

    Measured: Cross-sectional, 2-3 years after surgery for breast cancer

Secondary outcomes (2)
  1. Prevalence of persistent pain after reconstruction after mastectomy

    Self reported pain expressed as a percentage of the population of patients reconstructed with expander and autologous tissue. Pain intensity measured with a numerical rating scale 0-10, divided in mild (NRS 1-3), moderate (4-6) and severe pain (7-10). Patients regarded as having clinically relevant pain: NRS 4 or above, at least at a weekly basis.

    Measured: Cross-sectional, 2-3 years after surgery for breast cancer

  2. Prevalence of sensory disturbances after reconstruction after mastectomy

    Measured: Cross-sectional, 2-3 years after surgery for breast cancer

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Chronic Pain, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

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 1 inclusion and 4 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 30 Nov 2012. 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 Denmark. 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?

The risk of developing persistent if reconstructed (time frame: Cross-sectional, 2-3 years after surgery for breast cancer). 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 NCT01738048, which also lists 1 linked publication.

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 30 Nov 2012.
