Clinical Trial Summary

This is a dose escalation study involving stage IV breast cancer patients not progressing after 6 months of first line systemic treatment. Potential advantages of stereotactic body radiotherapy (SBRT) in treating breast primary tumor in metastatic breast cancer are:

• radio-biological advantage of a short highly effective treatment schedule

• possibility of preventing lesions to become symptomatic

• possibility of continuing systemic treatment without interruption

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Primary breast tumor local failure	2 years local failure probability of treated primary tumor predicted by CT planning images	2 years
Primary	Maximum tolerated dose of stereotactic body radiotherapy (SBRT)	the dose of radiotherapy associated with a = 20% rate pre-specified treatment-related dose -limiting toxicity (DLT) occurring within 6 months from the start of treatment. DLT is defined as any grade 3 or worse toxicity according to CTCAE v.4 related to the following specific symptoms: Radiation dermatitis grade > 3; Breast pain grade 3; Breast infection grade > 3; Breast asymmetry grade 3; Fibrosis grade > 3; Skin atrophy grade 3; Rib fracture grade 3; Chest wall pain grade 3	6 months
Secondary	Rate of long-term adverse events	scored according to the NCI CTCAE v. 4.2	2 years
Secondary	Breast Cosmesis	scored according to the European Organization for Research and Treatment of Cancer (EORTC) Cosmetic Rating System for Breast Cancer for the evaluation of cosmetics (score 1 to 4, no difference-large difference by comparing the treated breast to the controlateral breast) and carried out separately by the doctor and the patient	2 years
Secondary	QoL	scored according to the EORTC quality of life questionnaire (QLQ) in breast cancer patients (EORTC QLQ-C30 / BR23)	2 years
Secondary	Primary breast tumor best response	evaluated according to Response Evaluation Criteria in Solid Tumours (RECIST v1.1)	2 years
