    Abstract:
    Axillary node dissection has been a routine part of breast cancer treatment for more than 100 years. As so few patients have been shown to have positive nodes, more consideration should be given to eliminating axillary node dissection for duct carcinoma in situ (DCIS) and T1a lesions. And for patients with a T1/2N0M0 cancer of the breast, lumpectomy alone without axillary dissection followed by radiation therapy to the intact breast and regional lymph nodes should be a reasonable treatment method that avoids arm morbidity. Between September 1989 and December 1998, we treated 79 breast cancer patients with this method intensified with tamoxifen and CAF chemotherapy. Before the start of the therapy, we performed a thorough evaluation using helical CT and doppler ultrasonography to exclude patients with significant swelling of axillary lymph nodes (more than 5 mm in short diameter). Through the end of December 1998, the mean follow-up period was 52.6 months. Up to this date, only one patient of the 79 showed local recurrence within 5 years after the start of the treatment. This patient received a second lumpectomy. She then experienced lung metastases 6 months later. She is currently receiving combined chemotherapy with docetaxel and cisplatin. The cause-specific survival rate of these 79 patients maintained 100% at 6 years, and no axillary failure has been experienced so far. The cosmetic results in 50 (65.8%) of the 76 patients who were alive at the end of December 1998 were rated as excellent, 26 (34.2%) as good, and none as fair or poor. Therefore, we have concluded that this method of treatment for early breast cancer could eliminate surgical damage and allow good cosmetic results, and that survival rates with this treatment are excellent.
