Abstract:
122 patients with primary breast cancer were followed-up for a median of 4.6 years after surgery. The concentration of cathepsin D in tumour cytosol was strongly related to both metastasis-free survival and disease-free survival and was independent of nine conventional prognostic indices. Cathepsin D assay may prove particularly useful in identifying women who, though without lymph node involvement at presentation, are at high risk of metastatic disease.
