NCT01792726

Brief Summary

TARGIT-Boost is an international randomised clinical trial designed to test the hypothesis that the tumour bed boost delivered as a single dose of targeted intraoperative radiotherapy (TARGIT-B) is superior to the conventional course of external beam radiotherapy boost (EBRT-Boost), especially in women with high risk of local recurrence. It is a pragmatic trial in which each participating centre can use the local predefined inclusion/exclusion criteria for entry into the trial. Only centres with access to the Intrabeam® (Carl Zeiss) are eligible to enter patients into the trial. Eligible patients are those with a higher risk of local recurrence after breast conserving surgery. After giving consent patients are randomised to either TARGIT Boost or EBRT Boost. All patients will receive whole breast EBRT. They may receive any other adjuvant treatments as deemed necessary. The protocol recommends that patients be followed at six monthly intervals for three years and then annually. The primary endpoint is ipsilateral breast recurrence rate. Secondary endpoints are relapse-free survival, site of recurrence, overall survival (breast-cancer specific and non-breast cancer deaths) patient satisfaction and quality of life.

Outcome Measures

Primary Outcomes (1)

  • Local tumour control (defined as no recurrent tumour in the ipsilateral breast).

    To evaluate whether a tumour bed boost in the form of a single fraction of radiotherapy given intra-operatively and targeted to the tissues at the highest risk of local recurrence is superior (in terms of local tumour control) to standard post-operative external beam radiotherapy boost, after breast conserving surgery in women undergoing breast conserving therapy who have a higher risk of local recurrence.

    Five year median follow-up

Secondary Outcomes (5)

  • Site of relapse within the treated breast

    5 years median follow-up

  • Relapse-free survival

    Five year median follow-up

  • Overall survival

    Five year median follow-up.

  • Adverse events related to the primary treatment of the breast cancer.

    Five year median follow-up.

  • Quality of life assessed by patient completed validated questionnaires.

    Five year median follow-up

Study Arms (2)

TARGIT

EXPERIMENTAL

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.

Radiation: Boost to the tumour bed

External beam radiotherapy boost

ACTIVE COMPARATOR

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

Interventions

Boost to the tumour bed, with whole breast EBRT delivered according to local policy.

Eligibility Criteria

Sexfemale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • At least one of these criteria must be satisfied:
  • Less than 46 years of age
  • More than 45 years of age, but with one of the following poor prognostic factors:
  • lymphovascular invasion
  • gross nodal involvement (not micrometastasis)
  • more than one tumour in the breast but still suitable for breast conserving surgery through a single specimen
  • More than 45 years of age, but with at least two of the following poor prognostic factors
  • ER and/or PgR negative
  • Grade 3 histology
  • Positive margins at first excision
  • 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.
  • Lobular carcinoma or Extensive Intraductal Component (EIC)
  • 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.
  • Patients with either HER2 positive or HER2 negative can be included.

You may not qualify if:

  • Bilateral breast cancer at the time of diagnosis.
  • Patients with any severe concomitant disease that may limit their life expectancy
  • 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).
  • 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.
