Study Start Date:	April 1997

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.
