Abstract

Axillary lymph node dissection (ALND) is performed for staging purposes. Sentinel lymph node biopsy may decrease the cost and morbidity of ALND. Are there patients that the procedure is not indicated avoiding cost and morbidity? We retrospectively studied the incidence of lymph node metastasis in 423 patients with T1 breast cancer. Thirty-one T1a, 146 T1b, and 246 T1c tumors were seen. The mean age was 61 years. Ten per cent were premenopausal, and 84 per cent were postmenopausal. Tumor size averaged 1.29 cm. Eighty-one per cent of the tumors were node negative and 19 per cent were node positive. One T1a patient (3 per cent) had an axillary metastasis, 19 T1b patients (13%), and 61 T1c patients (25%) were node positive, respectively. Seventy-three per cent were ER positive. Thirty-three patients (8%) died from cancer. Eighty-seven per cent received surgery with axillary lymph node dissection (ALND), and three per cent had surgery without ALND. Younger age, increased tumor size, premenopausal status, and ER negativity affected node positivity rates (P < 0.05). Death from breast cancer was more common among node-positive patients (P < 0.05). No difference was found regarding the performance of ALND and survival (P > 0.05). We feel that ALND can be safely omitted in T1a to reduce the morbidity and the expense of breast cancer treatment. In T1b and T1c tumors, the use of ALND is necessary, but morbidity and cost can be reduced by the use of sentinel lymph node biopsy.
