Background: The 67-kd laminin receptor is a cell-surface protein that binds laminin with high affinity. In vitro studies suggest that this protein is involved in the progression of human tumors to invasive cancers (metastasis), but there have been few in vivo studies. Identification of such proteins would allow development of therapies aimed at interfering with their mechanisms of action. Purpose: This large retrospective study was designed to investigate the association of expression of this laminin receptor molecule with established prognostic factors and overall survival in breast carcinoma patients. Methods: We immunohistochemically stained archival paraffin-embedded sections of 1160 primary breast carcinomas, using an immunoperoxidase technique and the MLuC5 monoclonal antibody, which is specific for the 67-kd laminin receptor. Specimens were obtained from consecutive surgeries performed from January 1968 through December 1971. Patients with negative lymph nodes or involved regional nodes had been treated with surgery alone; those with positive axillary nodes had received surgery and radiotherapy. No chemotherapy had been administered until disease recurrence. The statistical analysis was carried out using the logrank method for the survival curves and the actuarial life table to calculate survival rates according to the different prognostic variables. Results: We found statistically significant associations between laminin receptor expression and young age (P
