Phase III Randomized Study of Postsurgical Radiotherapy vs No Treatment for in Situ Ductal Carcinoma of the Breast Treated by Wide Excision
Radiation Therapy Compared With No Further Treatment in Treating Patients With In Situ Ductal Breast Cancer
Basic Trial Information
|Phase III||Treatment||Closed||under 70||EORTC-10853|
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.
Biopsy-proven, noninvasive in situ ductal carcinoma of the breast of the following histologies: Solid Cribriform Papillary Clinging Comedo 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 biopsied Patients undergoing axillary clearance eligible if free of axillary metastases 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
Biologic therapy: Not specified Chemotherapy: Not specified Endocrine therapy: Not specified Radiotherapy: Not specified Surgery: Disease amenable to conservative surgery required
Age: Under 70 Menopausal status: Not specified Performance status: 0 or 1 Hematopoietic: Not specified Hepatic: Not specified Renal: Not specified Other: 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
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 recommended. 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.
