Breast cancer risk in papilloma patients: Osteopontin splice variants indicate prognosis

Abstract: Background Papillomas of the breast pose challenges for treatment decisions as their risk for transformation to breast cancer is low but not negligible. To spare low-risk patients the burden of substantial treatment side effects, prognostic indicators are needed for cancerous progression. The secreted metastasis mediator Osteopontin (OPN) is a marker for breast cancer aggressiveness, and its variants are prognosticators for transformation in diverse premalignant breast lesions. Here, we test wh… Show more

“…Most breast cancers produce the full-length form (OPN-a) together with the shortest splice variant (OPN-c). Remarkably, OPN-c is also present in a fraction of the premalignant lesions, where it reflects a high risk for progression to cancer within 5 years, regardless of the lesion's subtype [13,14]. With the simple immunohistochemical staining of the biopsied material, the individualized progression risk for that patient can be estimated with good sensitivity and specificity (Table 1), and it can lead to improved counseling.…”
