Abstract
We retrospectively made a clinicopathological study on 128 breast cancer patients with tumor 2cm and smaller who were received more than axillary lymph node dissection during recent two decades in our hospital. The results were as follows: 1) Comparative analysis between recurrent nine patients and not-recurrent 13 patients who had node positive breast cancer tumor 2cm and smaller showed that the former had more frequency than the latter of scirrhous cancer, lowgrade histologic differentation, fatty invasion, positive vascular invasion and lymph node metastases. 2) Metastasizing rate to lymph nodes of T1 breast cancers was sig-nigficantly higher tumors more than 16mm in diameter than those less than 15mm (p<0.05). 3) Recurrent TO·Tl-breast cancer patients had more than four lymph node metastases in tumors less than 15mm, and the patients with one lymph node metantasis had recurrence in tumors more than 16mm. We conclude that tumor size and lymph node metastasis are especially significant an the prognostic factors in TO·Tl-breast cancers and we must perform postoperative adjuvant therapy to the patients with breast tumor less than 15mm and more than four lymph node metastases, tumor more than 16mm and positive lymph node metastasis.
