Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||N/A and Over|
Inclusion Criteria:At least one of these criteria must be satisfied: 1. Less than 46 years of age 2.

More than 45 years of age, but with at least two of the following poor prognostic factors 1. ER and/or PgR negative 2. Grade 3 histology 3. Positive margins at first excision 4. Those patients with large tumours which have responded to neo-adjuvant chemo- or hormone therapy in an attempt to shrink the tumour and are suitable for breast conserving surgery as a result. 5. Lobular carcinoma or Extensive Intraductal Component (EIC) 6. A list (one to many) of high risk factors are present (as predefined in the policy document) that give a high risk of local recurrence. 7. Patients with either HER2 positive or HER2 negative can be included.
Exclusion Criteria:1. Bilateral breast cancer at the time of diagnosis. 2. Patients with any severe concomitant disease that may limit their life expectancy 3. Previous history of malignant disease does not preclude entry if the expectation of relapse-free survival at 10 years is 90% or greater (e.g., non-melanoma skin cancer, CIN, etc). 4. No more than 30 days can have elapsed between last breast cancer surgery (not axillary) and randomisation for patients in the post-pathology stratification unless part of a specific clinical trial that addresses the question of timing or tumour bed can be reliably identified, e.g., by ultrasound.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

DESIGN: A pragmatic multi-centre randomised clinical trial to test whether TARGeted Intraoperative radioTherapy as a tumour bed Boost (TARGIT-B) is superior in terms of local relapse within the treated breast compared with standard post-operative external beam radiotherapy boost in women undergoing breast conserving therapy who have a higher risk of local recurrence. Patients can be entered before the primary surgery or in a smaller proportion of cases, post-pathology. SETTING: Specialist breast units in UK, USA, Canada, Australia and Europe; 31 centres currently recruiting in the TARGIT-A trial and several are ready to join. TARGET POPULATION: Breast cancer patients suitable for breast conserving surgery, but with a high risk of local recurrence. Details of inclusion and exclusion are given in part 2. Briefly the patients should be either younger than 45 or if older, need to have certain pathological features that confer a high risk of local recurrence of breast cancer. HEALTH TECHNOLOGIES BEING ASSESSED. The TARGIT Technique: The Intrabeam® (Carl Zeiss, FDA approved and CE marked) is a miniature electron beam-driven source which provides a point source of low energy X-rays (50kV maximum) at the tip of a 3.2mm diameter tube. The radiation source is inserted into the tumour bed immediately after excision of the tumour and switched on for 20-35 minutes to provide intra-operative radiotherapy accurately targeted to the tissues that are at highest risk of local recurrence. The physics, dosimetry and early clinical applications of this soft x-ray device have been well studied. For use in the breast, the technique was first developed and piloted at University College London. The radiation source is surrounded by a spherical applicator, specially designed (and available in various sizes) to produce a uniform field of radiation at its surface, enabling delivery of an accurately calculated dose to a prescribed depth. It is inserted in the tumour bed and apposed to it with surgical sutures and/or other means. As the x-rays rapidly attenuate the dose to more distant tissues is reduced; this also allows it to be used in standard operating theatres. 20 Gy is delivered to the tumour bed surface in 20-35 minutes, after which the radiation is switched off, the applicator removed, and the wound closed in the normal way. This simple technique has potentially several advantages over convential external beam radiotherapy, interstitial implantation of radioactive wires or conformal external beam radiotherapy. The first pilot of twenty-five cases was at performed at UCL using TARGIT technique as a replacement for the boost dose of radiotherapy; full dose external beam treatment was subsequently given. The phase II study of 300 patients was published and recently updated with long term data along with favourable toxicity and cosmetic outcome results of individual cohorts. A mathematical model of TARGIT developed recently (funded by Cancer Research UK) suggests that it could be superior to conventional radiotherapy. Translational research has found that TARGIT impairs the surgical-trauma-stimulated proliferation and invasiveness of breast cancer cells. This effect of radiotherapy may act synergistically with its tumouricidal effect yielding a superior result. MEASUREMENT OF COST AND OUTCOME: Patient assessments will be clinical examination (6 monthly x 3 years then yearly x 10 years) and mammography (yearly). with ulstrasound (if needed) . Primary outcome: histologically/cytologically proven local recurrence. Secondary: site of relapse in the breast, overall survival, local toxicity (RTOG and LENT SOMA criteria), cosmesis, quality of life, patient satisfaction and health economics. The cost and cost-effectiveness of TARGIT versus EBRT, both as boost, will be calculated from a NHS and personal social services (PSS) perspective. Costs directly incurred by patients will also be assesed, since EBRT as a boost is likely to impose additional time and travel expense to patients and families.
The experimental policy is to give targeted intra-operative radiotherapy (TARGIT-Boost) in a single dose to substitute for the usual boost dose, in addition to whole breast external beam radiotherapy delivered according to local treatment guidelines.
Active Comparator: External beam radiotherapy boost
The conventional policy is to receive radiation boost to the tumour bed delivered by external beam radiotherapy (EBRT) in addition to whole breast external beam radiotherapy delivered according to local treatment guidelines.
Radiation: - Boost to the tumour bed
Boost to the tumour bed, with whole breast EBRT delivered according to local policy.
