From: Lymph vascular invasion in invasive mammary carcinomas identified by the endothelial lymphatic marker D2-40 is associated with other indicators of poor prognosis

  1. Mac-Met = macrometastases; Mic-Met = micrometastases; LNN = lymph node negative; LVI = lymphatic vessel invasion; BVI = blood vessel invasion; n = number of cases; H&E = hematoxylin and eosin; IHC = immunohistochemistry
  2. * p value = 0.002. The other p values were not statistically significant.
