Table 2 depicts the distribution of KLK14 expression, positive or negative, in breast tumour tissues in relation to other established prognostic factors such as menopausal status, tumour size, stage, grade, histological type, nodal status, steroid receptor status and adjuvant therapy. Patients with KLK14-positive breast tumours more frequently had advanced stage (III) disease (P=0.032). Significant associations between KLK14 expression and tumour size, grade and histology, or menopausal, nodal and steroid receptor status were not observed. Here, KLK14 is linked to breast neoplasm.
