Hypothesis The density of vasoactive endothelial growth factor receptor 3immunostained microvessels in primary breast cancers correlates with the incidence of axillary lymph node metastasis.
Design Breast cancer microvessel clusters ("hot spots") were sequentially immunostained for factor VIII, type IV collagen, and vasoactive endothelial growth factor receptor 3. Microvessels were counted under light microscopy at a magnification of x200. Axillary lymph nodes were evaluated for metastases by light microscopy.
Setting A multidisciplinary breast cancer clinic and laboratory.
Patients Sixty patients with T2 breast cancers treated by lumpectomy (or mastectomy) and axillary lymphadenectomy.
Main Outcome Measures Putative lymphatic microvessel density compared with axillary metastases.
Results There were 16% (SE, 1.4%) vs 4% (SE, 0.8%) vasoactive endothelial growth factor receptor 3immunostained microvessels (P<.001), 38% (SE, 3.9%) vs 65% (SE, 3.1%) type IV collagenimmunostained microvessels (P<.001), and 46% (SE, 4.1%) vs 31% (SE, 3.2%) unstained microvessels (P=.004) in node-positive vs node-negative patients, respectively. A fitted logistic model based on the relative percentage of putative lymphatic microvessels to blood microvessels correctly predicted that 23 (96%) of 24 patients would have a low risk and that 26 (96%) of 27 patients would have a high risk of lymph node metastases. Six (67%) of 9 patients predicted to have an intermediate risk had lymph node metastases.
Conclusion The odds of a patient with breast cancer having axillary lymph node metastasis increased substantially as the proportion of putative lymphatic microvessels increased and the relative proportion of blood microvessels in angiogenic hot spots decreased (log likelihood=14.6; 2=53.4; P<.001; area under the receiver operation characteristic curve=0.97).
