Περιγραφή
The value of various prognostic factors in breast cancer patients has been determined in a number of studies. One hundred thirty-eight Greek women were followed up over a 5-year period after surgery for breast cancer. Amplification and overexpression of c-erbB-2 was found in 22.4% and 29.7% of the respective cases, and the concentration of total cytosolic Cathepsin-D (CD) in 46.4% of them was high (> or = 60 pmol/mg protein). The examined biological variables were compared with standard clinicopathological prognostic factors for the disease and related to early relapse (ER; before 3 years), relapse-free survival (RFS; median, 5 years), and overall survival (OS; median, 5 years). It was found that high CD levels significantly shorten ER of both node-negative and node-positive patients (P < 0.0001 and P = 0.002, respectively) and have prognostic value for RFS and OS of node-negative patients (P = 0.0012 and P = 0.0288, respectively), but lose their value as relapse predictors for node-positive patients for periods longer than 3 years. Overexpression of c-erbB-2 was found to be predictive for OS of node-positive and -negative patients (P = 0.0048 and P = 0.0285, respectively), but its predictive power was weak for ER (P = 0.0456) and RFS (P = 0.0455) of node-negative patients and disappeared for node-positive patients. c-erbB-2 amplification offers minimal assistance to the prediction. In conclusion, high CD concentration is indicative of ER of patients, and c-erbB-2 overexpression correlates with OS of patients.
