Is lymph vascular invasion in invasive mammary carcinomas identified by the endothelial lymphatic marker D2-40 associated with other indicators of poor prognosis?
D2-40 is a reliable marker of lymphatic vessels and is a useful tool for lymphatic emboli identification in immunostained sections of breast carcinomas with higher identification rates than H&E. Lymphatic vessel invasion was related to other features (high combined histologic grade, high Ki67 score, negative hormone receptors expression) associated with worse prognosis, probable reflecting a potential for lymphatic metastatic spread and aggressive behavior.
In this large, representative, community-based sample of women, there is a high prevalence of untreated moderate to severe VMS even in women aged 60 to 65 years. The use of vaginal estrogen and nonhormonal prescription therapy with proven efficacy for treatment of menopausal symptoms is strikingly low, suggesting that menopause remains an undertreated condition.
