I. Test the hypothesis that segmental mastectomy with or without axillary dissection followed by postoperative breast irradiation is more effective than segmental mastectomy with or without axillary dissection alone in controlling the subsequent occurrence of ipsilateral invasive and/or noninvasive cancers in patients with noninvasive intraductal adenocarcinoma.

General Eligibility Criteria:
Female patients aged 18 years and over who have undergone a segmental mastectomy for histologically confirmed noninvasive intraductal adenocarcinoma (those with mixed intraductal and lobular in situ are also eligible). If axillary dissection was performed, all axillary lymph nodes must be negative for tumor on histologic examination. The interval between the definitive operation and the proposed randomization may be no more than 56 days. Patients whose histologic diagnosis (including excisional, incisional, or needle biopsy and aspiration cytology) was established more than 8 weeks prior to segmental mastectomy are ineligible. The life expectancy, excluding the diagnosis of breast cancer, must be at least 10 years, and patients must not be pregnant at the time of the proposed randomization. Patients with diffuse microcalcifications in whom segmental mastectomy would be inadequate to resect all foci are ineligible, as are those presenting with more than one tumor mass in the same breast unless it is demonstrated that only one of the masses contains intraductal cancer, i.e., all other masses are benign. The presence of one or more ipsilateral axillary lymph nodes that are positive for tumor on histologic examination excludes, as does bilateral malignancy or a mass in the contralateral breast unless there is biopsy proof that the mass is not a malignancy (mirror image biopsy or blind biopsy is not required). Patients with suspicious palpable nodes in the contralateral axilla or with palpable supraclavicular or infraclavicular nodes are ineligible unless there is biopsy evidence that these nodes are not involved with tumor. There may be no previous or concurrent malignancy (including prior noninvasive breast cancer) except for squamous or basal cell carcinoma of the skin that has been effectively treated and carcinoma in situ of the cervix that has been treated operatively only. Prior therapy for the present breast cancer, including radiotherapy, chemotherapy, immunotherapy, and/or hormonal therapy, is not allowed; patients receiving hormonal therapy such as birth control pills or replacement therapy are eligible if this therapy is discontinued while on protocol. Nonmalignant systemic disease (e.g., cardiovascular, renal, or hepatic) that would preclude any of the treatment options or prevent prolonged follow-up excludes, as do any psychiatric or addictive disorders that would preclude obtaining informed consent. Patients with Paget's disease of the nipple, those with breasts deemed too large to permit satisfactory irradiation, and those who received breast irradiation following segmental mastectomy but prior to randomization are ineligible. A registry of lobular in-situ patients will be initiated; such patients must be registered within 56 days following definitive surgery. The same entry information and follow-up requirements already outlined in the protocol are to be utilized. However, the primary therapies are at the discretion of the investigators.
As of 05/90, it was anticipated that the required 775 patients would be entered by 12/31/90.
Randomized study. Arm I: Postoperative Radiotherapy. Irradiation of all remaining ipsilateral breast tissue using Co60 or linear accelerator x-rays. Arm II: No postoperative therapy.

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.
