Abstract
We analyzed survival of 102 invasive ductal, node positive breast cancer patients, treated with surgery and adjuvant chemotherapy (anthracyclines and/or taxanes) with relation to: (a) well-known clinicopathological parameters, (b) MIB-1 labeling index (LI), (c) the distribution of podoplanin-positive vessels (DPV), expression of: (d) basal markers, and (e) fascin. Lower progression risk was found for patients with tumors characterized by (i) pN1 + pN2, (ii) MIB-1LI ≤ 28%, (iii) lack of lymphatic vessels or high tumor DPV than for patients with pN3, MIB-1LI > 28%, low DPV, respectively. Cox multivariate analysis revealed that both pN3 and low DPV were negative prognostic indicators.
