Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study has been designed to compile information on the efficacy of the MammoSite RTS providing sole radiation therapy for patients with pure DCIS.

Detailed Description

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

Data relevant to the evaluation of the efficacy and safety of the MammoSite RTS system in providing radiation therapy to patients with DCIS will be collected. The MammoSite is a radionuclide applicator designed to deliver internal radiation therapy (brachytherapy) in patients with breast tumors following breast tumor resection surgery (lumpectomy).

MammoSite Radiation Therapy System

Intervention Type DEVICE

The MammoSite is a balloon catheter that is designed to position a radioactive source inside the lumpectomy cavity. The MammoSite applicator is inserted into the cavity created by the tumor removal surgery. The MammoSite applicator is then inflated and expands to fill the cavity.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Pre-Surgery:

* Unicentric pure DCIS
* Lesions should have a greatest dimension of 3 cm or less as determined by pre-surgery mammography and MRI
* Post-Surgery:

* Negative histological margins confirmed prior to beginning radiation therapy.
* Margins are positive if there is tumor at the inked margin.
* Classified as low (NG1), intermediate (NG2) or high (NG3) nuclear grade DCIS, using the Philadelphia Consensus Conference Guidelines are eligible
* Clinically node negative

Exclusion Criteria

* Distance from the balloon surface to the surface of the skin \< 5mm as determined by CT imaging.
* Distant metastases.
* Invasive or in-situ lobular carcinoma (post-surgery assessment).
* Nonepithelial breast malignancies such as sarcoma or lymphoma.
* DCIS that is multicentric in the ipsilateral breast.
* Pregnant or lactating.
* Prior non-hormonal therapy for the present breast cancer, including radiation therapy and/or chemotherapy.
* Collagen vascular diseases
* Coexisting medical conditions with life expectancy \< 2 years.
* Serious psychiatric or addictive disorder
* Previously treated contralateral breast carcinoma
* Synchronous bilateral breast carcinoma.
* Other malignancy, except non-melanoma skin cancer, \< 5 years prior to participation in the study; the disease free interval from any prior carcinoma must be continuous.
* Patients with diffuse disease
