Mammographically detected breast cancers and the risk of axillary lymph node involvement: is it just the tumor size?

摘要: PURPOSE In early breast cancer the knowledge of risk axillary node involvement is important in determining local as well systemic therapy. Because increased acceptance mammography, there has been an increase diagnosis small, mammographically detected tumors. The objective this study to determine whether cancers have a lower compared those clinically. PATIENTS AND METHODS From our patient database stage I and II we identified 980 patients with tumors RESULTS Fourteen percent had positive nodes 26% clinically Eight single positive, while 11% node. Thirteen ≤1 cm 25% 1.1 2 nodes. smaller size could explain proportion nodes, analyzed separately ≤ 1 group tumors, 9% if they were 19% detected. Four 5% multiple If palpable 10% Mammographically similargrade multivariate analysis, method detection remains significant variable impacting on even cm. DISCUSSION independent tumor or grade. Mammography detects their metastatic progression. majority node-positive who are Method may need be considered when assessing incorporated staging.
