Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Intraoperative Radiotherapy (IORT)

Arm Description

Patients with diagnosis of invasive breast cancer (IBC) will be treated with conservative surgery (with or without oncoplastic surgery) and 20 Gy IORT followed by hypofractionated radiotherapy.

Outcomes

Primary Outcome Measures

Changes in Cosmetic results - BCCT
It will be measured by the BCCT.core software programme. This software uses 4 photographies of the breast for each timepoint and evaluates cosmetic outcome based upon symmetry, skin colour changes and surgical scar appearance. The lower the calculated score, the better the cosmetic outcome (1=excellent, 2=good, 3=fair, 4=poor)
Changes in Cosmetic results - Self Evaluation using YBT
Questionnaire for cosmetic self-evaluation from the Young Boost Trial (YBT) that consists s of 8 questions about various aspects (size, shape, skin colour, massiveness of the breast, nipple position, general appearance, visibility of the surgical scar, and overall satisfaction) to evaluate the degree of satisfaction of the patients themselves about the cosmetic results.

Secondary Outcome Measures

Changes in Quality of life (QOL) - General
It will be measured by the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaires QLQ-C30
Toxicity (acute and late)
Defined according to the NCI criteria published in the Common Terminology Criteria for Adverse Events (CTCAE) v4.0
Local control
Defined as histologically-confirmed evidence of tumour recurrence in the ipsilateral breast
Changes in Quality of life (QOL) - Breast
It will be measured by the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaires QLQ-BR23
