3-Dimensional Conformal Radiation Therapy In Treating Women With Stage I or Stage II Breast Cancer Previously Treated With Lumpectomy and Axillary Node Dissection
A Phase I/II Trial to Evaluate Three Dimensional Conformal Radiation Therapy (3D-CRT) Confined to the Region of the Lumpectomy Cavity for Stage I and II Breast Carcinoma
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.
연구 개요
상세 설명
OBJECTIVES:
- Determine the technical feasibility and reproducibility of three-dimensional conformal radiotherapy confined to the region of the lumpectomy cavity in women with stage I or II breast cancer.
- 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.

설명
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 eligible:
- Invasive ductal
- Medullary
- 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
- No distant metastases
