I.  Determine what proportion of patients with in situ ductal carcinoma of the 
breast may be treated by a conservative procedure.

II.  Determine whether wide excision alone or in combination with external 
breast irradiation provides adequate treatment for in situ ductal carcinoma of 
the breast.

Entry Criteria

Disease Characteristics:

Biopsy-proven, noninvasive in situ ductal carcinoma of the breast of the
following histologies:

Tumors up to 3 cm in diameter (5 cm optionally) must be amenable to
conservative surgical procedure

Lumps and discrete areas of microcalcification must have been completely
excised with a 1 cm margin with pathologically confirmed negative margins

No evidence of tumor spread after staging investigations 

No axillary metastases
  Clinically enlarged axillary nodes suspected of containing tumor should be

  Patients undergoing axillary clearance eligible if free of axillary

No bilateral in situ ductal carcinoma

No Paget's disease of the nipple

Patients excluded because of tumor size or incomplete excision were registered
for follow-up alone until December 1993

Hormone receptor status:
  Not specified

Prior/Concurrent Therapy:

Biologic therapy:
  Not specified

  Not specified

Endocrine therapy:
  Not specified

  Not specified

  Disease amenable to conservative surgery required

Patient Characteristics:

  Under 70

Menopausal status:
  Not specified

Performance status:
  0 or 1

  Not specified

  Not specified

  Not specified

  No second malignancy except:
     Adequately treated basal cell skin carcinoma
     Cone-biopsied carcinoma in situ of the cervix
  No mental or social contraindication to long-term follow-up
  No pregnant women

Expected Enrollment

100 patients/year are expected to be entered over 1.5 years until a successor 
trial is available or until up to 1,000 evaluable patients have been entered.  
As of August 1995, 879 patients have been entered; entry will continue until a 
successor trial becomes available.


This is a randomized study.  Patients are randomized following wide excision.

One group receives radiotherapy to the breast; radiotherapy must begin within 
12 weeks of surgery.  Patients with a locoregional recurrence then undergo 
total mastectomy.

The other group is observed only.  Patients who experience a locoregional 
recurrence may then undergo re-excision and, if the margins are clear, 
subsequent radiotherapy.  If the margins are not clear, total mastectomy is 

If in either group the recurrence is histologically determined to be 
infiltrating carcinoma, the patient is treated according to the policy of the 
participating institution while follow-up continues on this study.

It is recommended that patients be followed every 3 months for 3 years, every 
6 months until the 10th postoperative year, and yearly thereafter.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
