This trial is active, not recruiting.

Condition breast cancer
Treatments photon, 3d-proton/conventional plan or 3d-proton only
Phase phase 2
Sponsor University of Florida
Start date April 2012
End date March 2014
Trial size 18 participants
Trial identifier NCT01365845, UFPTI 1016-BR01


The purpose of this study is to determine if proton radiation therapy will reduce the amount of heart that is exposed to radiation, thereby decreasing the frequency and/or severity of any cardiac side effects.

Study Design

Allocation non-randomized
Endpoint classification safety/efficacy study
Intervention model parallel assignment
Masking open label
Primary purpose treatment
(Active Comparator)
Conventional photon plan
50.4 Gy to the breast/chest wall and peripheral lymph nodes at 1.8 Gy per fraction
3D-Proton/Conventional plan or 3D-proton only
3d-proton/conventional plan or 3d-proton only
50.4 Cobalt Gray Equivalent/Gray to the breast/chest wall and peripheral lymph nodes at 1.8 Cobalt Gray Equivalent/Gray per fraction

Primary Outcomes

Volume of Heart Receiving ≥ 5 Gray (Gy)/Cobalt Gray Equivalent (CGE)
time frame: 2 weeks prior to starting radiation therapy.

Secondary Outcomes

Secondary Dosimetric Endpoint
time frame: 2 weeks prior to starting radiation therapy.
Assessment of Acute Side Effects
time frame: Participants will be assessed weekly during radiation therapy for an expected average of 7 weeks.
Assessment of Longterm Side Effects and Disease Specific End Points.
time frame: 1 month following completion of treatment, then every 6 months for 5 years, then annually thereafter.
Assessment of Cardiac Function Markers
time frame: after treatment

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Pathologically confirmed invasive adenocarcinoma of the breast stage I-III (TX, T0-4, N0-3) with medially located tumor and/or axillary node invasion. - Patients must have undergone either mastectomy or breast conservation surgery. - Patients are required to have axillary staging which can include sentinel node biopsy alone if sentinel node is negative. - Patient must require peripheral lymph node radiation per physician discretion. Exclusion Criteria: - Evidence of distant metastasis (M1). - Prior radiotherapy to the area of interest. - Prior history of cardiovascular disease per physician discretion. - Prior or concurrent cancer other than non-melanomatous skin cancer unless disease free for at least 5 years. - Collagen vascular disease, specifically dermatomyositis with a CPK level above normal or with an active skin rash, systemic lupus erythematosis or scleroderma.
