About this study

Official title: WILL MULTIFUNCTIONAL MAGNETIC RESONANCE TECHNIQUES, DETAILED HISTOPATHOLOGICAL ANALYSIS AND PRONE TREATMENT POSITION IMPROVE ACCURACY OF TARGET VOLUME LOCALISATION & DEFINITION AND REDUCE EXPOSURE OF NORMAL TISSUES IN BREAST RADIOTHERAPY?

RATIONALE: Diagnostic procedures, such as multifunctional magnetic resonance imaging and CT scans, may help reduce normal tissue damage in patients undergoing radiation therapy for cancer.

PURPOSE: This clinical trial is studying how well radiation therapy planning techniques work in reducing damage to normal tissue in women undergoing breast-conserving surgery for ductal breast carcinoma.

Read the detailed description

OBJECTIVES:

  • To improve precision of tumor bed localization and definition of clinical target volume, and to reduce normal tissue irradiation in women undergoing partial breast or breast boost radiotherapy.
  • To test whether post-operative MRI improves the precision of tumor bed delineation after wide-local excision in comparison with the current standard CT scan/clip method.
  • To determine the impact of tumor position within the excision specimen upon the localization of clinical target volume in relation to the tumor bed.
  • To compare theoretical non-target tissue exposure from partial breast irradiation planned in the supine and prone (face-down) positions.

OUTLINE: Patients undergo planned breast-conservation surgery and placement of titanium clips to the four radial, the deep, and superficial margins of the excision cavity (for localization of tumor bed).

Within 2 weeks after surgery, patients undergo supine radiotherapy-planning CT scan as standard analysis. Patients then undergo a radiotherapy-planning CT scan in the prone position. Patients complete a linear analogue questionnaire after both scans designed to assess patient comfort and anxiety in each position. Patients then undergo multifunctional MRI (including dynamic contrast-enhancement MRI and diffusion-weighted MRI) of the ipsilateral breast in the prone position (≥ 3 weeks after surgery). If suspicious lesions ≥ 5 mm are found on MRI, patients are referred for a second-look ultrasound with biopsy (if lesion visible on ultrasound); where suspicious lesions are seen only on MRI, patients undergo MRI-guided biopsy. Lesions < 5 mm are included in the whole-breast radiotherapy treatment.

What is being measured

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

  1. Difference in lung NTDmean (biologically weighted [normalized] mean of total dose to lung normalized to 2 Gy fractions) in supine vs prone positions

Secondary outcomes (7)
  1. Closeness of agreement between MRI-based vs CT scan/clip- based delineation of tumor bed

  2. Closeness of agreement between clinical target volumes (CTVs) defined using uniform margin vs those defined using knowledge of all excision margins

  3. Difference in NTDmean to ipsilateral non-planning target volume (PTV) breast tissue, chest wall muscle, and heart

  4. Difference in mean volume of PTV in supine versus prone positions

  5. Difference in dose homogeneity within PTV in each position

  6. Difference in complexity of beams needed to achieve above dose homogeneity within PTV

  7. Patient comfort with each positioning technique (assessed by questionnaire)

Questions about this trial

What is this clinical trial studying?

A study testing questionnaire administration, adjuvant therapy and biopsy in people with Breast Cancer, run by Royal Marsden NHS Foundation Trust at 1 site in United Kingdom.

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 2 inclusion and 7 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 26 Jun 2013. 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 United Kingdom. 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?

Difference in lung NTDmean (biologically weighted [normalized] mean of total dose to lung normalized to 2 Gy fractions) in supine vs prone positions. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 26 Jun 2013; AzTrials last refreshed its copy on 27 Oct 2026.
