METHODS: Between 1995 and 1999, 48 patients with locally advanced breast cancer were submitted to induction chemotherapy at Fundacion Tejerina--Centro de Patologia de la Mama, Madrid, Spain.
Core biopsies were performed in all cases prior to treatment for histological diagnosis which allowed for the determination of the following parameters by means of immunohistochemistry: hormone receptors (ER and PR), oncogenes and tumor suppressor genes (c-erb-B2 and p53) and the proliferation marker Ki67.

Patients and Methods: We reviewed the records of 135 patients with unifocal invasive breast cancers, 2 cm or less in diameter, operated upon at 'Fundacion Tejerina-Centro de Patologia de la Mama', Madrid, Spain, between January 1993 and December 1997.
Additionally, Ki67, c-erb-B2, p53, nm23, HSP27, HSP60 and CD44std expression was studied on archival, paraffin-embedded tumor material from these same patients by means of immunohistochemistry.

Markers of hormone dependence (estrogen and progesterone receptors), proliferation (Ki67 and DNA-ploidy), angiogenesis (VEGF and CD105), as well as oncogene (c-erb-B2), and tumor suppressor gene (p53) expression were also analyzed.

MATERIALS AND METHODS: This study was restricted to the ductal infiltrating variety only, and to pT1 size using the immunohistochemical markers estrogen receptor (ER), progesterone receptor (PR), HER2 and cytokeratin 5/6.

Using this technique, we have studied a series of 212 early (pT1) unifocal breast cancers and have correlated the expression of uPA-PAI-1 complexes, together with other clinical and biological features (histologic variety, histologic and nuclear grade, hormone receptors, Ki67 labelling index, c-erb-B2-, p53- and CD44std-expression) with or without the occurrence of axillary node invasion.
