Objectives

I.  Determine the results of breast-conserving therapy (radiotherapy plus 
surgery) for operable breast cancer with regard to survival, length of 
disease-free period, and quality of life (cosmetic results, psychologic 
factors, functional tests of arm movements).

Entry Criteria

Disease Characteristics:

See General Eligibility Criteria

Patient Characteristics:

See General Eligibility Criteria

General Eligibility Criteria:

Patients with Stage I or II 
histologically proven breast carcinoma; axillary lymph node metastases must 
either be absent or operable.  Patients must be less than 71 years of age and 
have a Karnofsky performance index of 80 or greater.  There must not be other 
malignant tumors except nonmelanomatous skin tumors.  Patient must be 
accessible for prolonged follow-up.

Expected Enrollment

1,000 patients will be entered.

Outline

Randomized study.  Patients with histological proof of axillary node 
involvement also receive Adjuvant Therapy.
Arm I:  Surgery plus Radiotherapy.  Radical mastectomy; plus parasternal field 
and axillary field megavoltage irradiation.
Arm II:  Surgery plus Radiotherapy.  Lumpectomy; plus external megavoltage 
irradiation of the breast and booster tumor bed irradiation by Iridium 
implants.
Adjuvant Therapy:  3-Drug Combination Chemotherapy.  CMF:  Cyclophosphamide, 
CTX, NSC-26271; 5-Fluorouracil, 5-FU, NSC-19893; Methotrexate, MTX, NSC-740.
