Purpose
RATIONALE: 3-dimensional conformal radiation therapy delivers a high dose of radiation directly to the tumor and may kill
more tumor cells and cause less damage to normal tissue.
PURPOSE: Phase I/II trial to study the effectiveness of 3-dimensional conformal radiation therapy in treating women who have
undergone lumpectomy and axillary node dissection for stage I or stage II breast cancer.

Official Title: Phase I/II Study of Three-Dimensional Conformal Radiotherapy In Women With Stage I or II Breast Cancer Previously Treated
With Lumpectomy and Axillary Node Dissection
Further Study Details:
OBJECTIVES:
- Determine the technical feasibility and reproducibility of three-dimensional conformal radiotherapy in women with stage I
or II breast cancer previously treated with lumpectomy and axillary node dissection.
- Determine the cosmetic results in patients treated with this regimen.
- Determine the complication rates in patients treated with this regimen.
- Determine the local control rate in patients treated with this regimen.
OUTLINE: This is a multicenter study.
Patients undergo three-dimensional conformal radiotherapy twice daily for 5 days beginning within 8 weeks after surgery.
Patients are followed at 6 weeks, every 3 months for 1 year, every 4 months for 1 year, every 6 months for 3 years, and then
annually thereafter.
PROJECTED ACCRUAL: A total of 19-46 patients will be accrued for this study within 6.3 to 15.3 months.

DISEASE CHARACTERISTICS:
- Histologically confirmed invasive breast cancer
- Stage I or II (T1, N0; T1, N1; T2, N0; or T2, N1)
- Unifocal disease (single focus that can be encompassed by one lumpectomy)
- The following histologies are eligilble:
- Invasive ductal

- Papillary
- Colloid (mucinous)
- Tubular
- No invasive or extensive in situ lobular carcinoma or pure ductal carcinoma in situ (DCIS)
- No nonepithelial breast malignancies such as sarcoma or lymphoma
- Previously treated with lumpectomy of a lesion no greater than 3 cm and axillary dissection of at least 6 lymph nodes or a
sentinel node biopsy
- Six surgical clips in place delineating the margins of the tylectomy cavity
- Negative, inked histologic margins of lumpectomy (greater than 2 mm) OR re-excision specimen available for confirmation
- Negative mammography post-lumpectomy or post-excision if malignancy-associated microcalcifications were initially present
- No prior lumpectomy so extensive that the cosmetic result is low or poor prior to radiotherapy
- No more than 3 positive axillary nodes
- No proven multicentric carcinoma (tumors in different quadrants of the breast or tumor separated by at least 4 cm) with other
clinically or radiographically suspicious areas in the ipsilateral breast unless negative by biopsy
- No palpable or radiographically suspicious contralateral axillary, supraclavicular, infraclavicular, or internal mammary nodes
unless nodes are histologically negative
- No extensive intraductal carcinoma, indicated by one of the following according to the Harvard definition:
- More than 25 % of invasive tumor is DCIS and DCIS is in adjacent breast tissue
- Intraductal carcinoma with microinvasion
- No previously treated contralateral breast cancer or synchronous ipsilateral breast cancer
- No evidence of suspicious microcalcifications
- No Paget's disease of the nipple
- No skin involvement by disease, regardless of tumor size
