Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective single-arm phase II study designed to study the efficacy of high dose rate (HDR) brachytherapy with CT-imaging, single-fraction intraoperative radiation therapy (IORT). The study will accrue patients with early-stage breast cancer who will be treated with breast-conserving surgery (BCS). The main clinical eligibility criterion is based on suitability for accelerated partial breast irradiation. Patients may be eligible prior to receiving BCS or within 30 days of receiving BCS. Eligible patients that will undergo BCS will receive surgery according to the standard clinical practice in the Brachytherapy Suite in the Emily Couric Clinical Cancer Center. Patients that have already undergone BCS must meet all other eligibility criteria and are able to be treated with IORT within 30 days of their breast surgery. Eligible subjects will undergo a lumpectomy or re-excision lumpectomy according the standard clinical practice. Immediately following lumpectomy, the breast HDR brachytherapy applicator will be placed and CT imaging will be performed for treatment planning. After HDR brachytherapy is delivered, the applicator will be removed, and the breast surgeon will complete the skin closure. Although the ultimate goal of the study is to determine 5-year ipsilateral breast tumor recurrence (IBTR), all efforts will be made to follow the patients until death.

IORT with CT-Guided HDR Brachytherapy

Patients will receive IORT with CT-guided HDR brachytherapy at the time of breast surgery.

Group Type EXPERIMENTAL

IORT with CT-Guided HDR Brachytherapy

Intervention Type DEVICE

This therapy targets the cancer cells directly, reducing the volume of breast tissue exposed to the radiation and the risks involved with the radiation. CT imaging will be used via a multichannel/multi-dwell balloon catheter to better sculpt the cancer away from the heart, skin, and ribs.
