A clinicopathological study was conducted on 26 patients undergoing conservative breast surgery breast-conserving surgery [BCS] in 17, and 9 subcutaneous mastectomies with axillary dissection [SM] in 9, and 23 patients treated by BCS+ radiotherapy in our hospital between 1992 and July 1995. BCS was performed in 11% of all 160 breast cancers. The mean age of the patients was 50.8 years. There were 2 Tis lesions, 8 stage I, and 7 stage II. Mean tumor size was 1.9cm and tumor-nipple distance was 4.7cm. Surgical methods consisted of 2 quadrantectomies, 14 wide excisions and one lumpectomy. Fourteen patients were given subsequent radio therapy to the breast. Axillary node metastasis was positive in 4 of 16 cases. During a median follow-up period of 22 months, no patient developed recurrence. The SM patients had 2 Tis lesions, 1 stage I and 6 stage II with a mean tumor size of 2.7cm and a tumor-nipple distance of 3.1cm. They were all negative for node metastasis. Seven patients underwent breast reconstruction. The patients with BCS plus radiotherapy received a total dose of 50 Gy with 10 MV Linac X-rays. There were few side effects of radiation, and the cosmetic results were almost always good. The breast conserving-procedures have yielded a satisfactory cosmetic appearance and good outcome.
