Brief Summary:
RATIONALE: The evaluation of breast cancer recurrence rates may improve the ability to plan cancer treatment for patients with breast cancer.
PURPOSE: Study to evaluate the rate of recurrence of breast cancer in women who have had surgery for ductal carcinoma in situ.
Detailed Description:
OBJECTIVES:
* Evaluate actuarial local in situ and invasive recurrence rates at 5 and 10 years after local excision in women with a favorable ductal carcinoma in situ (DCIS) prognosis.
* Evaluate concordance between institutional pathologists and central review pathologists with respect to diagnosis and grading of DCIS.
* Identify parameters that indicate increased or decreased risk of recurrence in the absence of irradiation.
* Evaluate patterns of salvage of recurrence and rates of breast conservation.
* Evaluate actuarial relapse-free, overall, and cause-specific survival at 5 and 10 years post DCIS excision.
OUTLINE: This is a registration study stratified by histologic grade (high vs low or intermediate) and adjuvant tamoxifen therapy (yes vs no).
Patients receive standard clinical and mammographic follow-up for greater than 10 years. If recurrence occurs, treatment will be at the discretion of the investigators. Patients may receive adjuvant oral tamoxifen daily for 5 years after local excision.
A follow up magnification view mammogram must be taken after the last local excision, and microcalcification must be negative.
Patients are followed every 6 months for the first 10 years, and then annually thereafter.
PROJECTED ACCRUAL: 1000 (500 per stratum) eligible and evaluable patients will be enrolled at an estimated accrual rate of 250 patients per year.
