AIM: Several randomized trials on conservative surgery compared with mastectomy in early-stage breast cancer have validated this technique in terms of local and distant relapse and survival of patients. Standard conservative approach includes surgical removal of the cancer with adequate cancer-free margins, axillary dissection, postoperative breast irradiation and adjuvant treatments when required.
METHODS: From 1987 to 2003, 500 early stage breast carcinoma were treated on 494 patients with conservative surgery and postoperative radiotherapy. Surgery consisted in a wide tumorectomy, with intraoperative control of R0 margins. The total postoperative radiation dosage was 50 Gy on the whole breast, associated with a boost of 10 Gy on tumor bed (20 Gy in T2 neoplasms). Before 1997 node-positive patients were treated with axillary irradiation with 50 Gy. Postoperative chemotherapy and/or hormonal therapy were administered to patients according with node-involvement, age and menopausal status. AJCC-stage was T1N0 in 44%, T2N0 in 15%, T1N1 in 19% and T2N1 in 22% of the patients.
RESULTS: In a postoperative setting, we observed 9% of axillary seromas or hematomas and 7% of oedema of the arm. At a median follow-up of 150 months (range 48-248 months), actuarial local recurrence rates were 7% at 5 years and 14% at 10 years. The actuarial rates of distant metastases were 18% at 5 years and 33% at 10 years. Ten-year overall and disease-free survival rates were 81% and 60%, respectively. Cosmetic results were good/excellent in 80%, satisfactory in 10% and poor in 10% of patients.
CONCLUSION: Recurrence and survival rates in breast-conserving surgery are consistent with indexed literature on conservative treatment of early breast cancer. Women eligible for conservative treatment should be offered the choice of either wide tumorectomy or quadrantectomy with axillary lymph nodes removal and postoperative radiotherapy, or modified radical mastectomy.
