Radiation Therapy in Treating Post-Menopausal Women With Early Stage Breast Cancer Undergoing Surgery

Stopped early · Phase 2

Conditions studied: Ductal Breast Carcinoma In Situ, Estrogen Receptor Negative, Estrogen Receptor Positive, HER2/Neu Negative, Invasive Cribriform Breast Carcinoma, Invasive Ductal Carcinoma, Not Otherwise Specified, Lobular Breast Carcinoma In Situ, Mucinous Breast Carcinoma, Papillary Breast Carcinoma, Progesterone Receptor Positive, Stage I Breast Cancer, Stage II Breast Cancer, Stage IIIA Breast Cancer, Stage IIIC Breast Cancer, Tubular Breast Carcinoma

In brief

This phase II trial studies how well radiation therapy works in treating post-menopausal women with early stage breast cancer undergoing surgery. Radiation therapy uses high energy x rays to kill tumor cells. This may be an effective treatment for breast cancer.

Who can join

Age: 50 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Core needle biopsy (e.g. Mammotome, core, stereotactic, ultrasound guided) showing invasive mammary cancer (with or without concomitant ductal carcinoma or lobular carcinoma in situ) or ductal carcinoma in situ; acceptable histologic types of invasive mammary cancer include ductal, tubular, mucinous, papillary, cribriform and "NOS" (not otherwise specified); invasive lobular cancer is excluded
• Age >= 50 years and postmenopausal with no menses for at least one year prior to study enrollment
• Age > 70 years with invasive breast cancer clinical size =< 3 cm OR Age 50 - 70 years with invasive breast cancer clinical size =< 1.5 cm OR Age >= 50 years and postmenopausal with any grade ductal carcinoma in situ (DCIS) clinical extent =< 1.5 cm (clinical tumor size will be determined by pre-operative breast imaging-mammography, ultrasound and/or magnetic resonance imaging; in cases of multiple measurements, the largest recorded single dimension will be used to determine eligibility)
• Hormone receptor status
• Estrogen or progesterone receptor positive or
• Estrogen and progesterone receptor negative and clinical tumor size =< 1.0 cm
• Human epidermal growth factor receptor 2 (HER2)/neu negative on the core biopsy analysis defined as 0 or 1+ by immunohistochemistry or not amplified by fluorescent in situ hybridization analysis
• Tumor >= 0.5 cm from skin as defined by breast ultrasound
• Unicentric tumor
• Axillary lymph nodes negative by pre-operative physical examination in all cases and pathologic examination from surgery for invasive disease
• Negative surgical margins, defined as no margin-labeling ink on tumor cells from margin evaluation

You may not qualify if…

• Initial core biopsy showing invasive lobular cancer
• Estrogen receptor and progesterone receptor negative tumor with clinical size > 1 cm
• Any Her 2+ breast cancer (immunohistochemistry 3+; or amplified by fluorescence in situ hybridization [FISH])
• Cancer in a patient with a known inherited susceptibility mutation in breast cancer (BRCA)1 or BRCA2
• Multicentric breast cancer (two foci of known cancer in the breast separated by greater than 5 cm, or in separate quadrants
• Clinically or pathologically positive axillary lymph nodes
• Any prior breast cancer
• Prior breast radiation therapy
