Prognosis
If lymph nodes are negative, the five- and 10-year survival is 85% and 79%, respectively. If the lymph nodes are positive, it is 32% and 28%. Involvement of the lymph nodes does not directly cause any harm, but it is a merely an indicator of systemic spread.
Furthermore, patients with an identifiable associated underlying breast tumor have a survival rate of 38-40% at five years and a survival rate of 22-33% at 10 years. The death rate of metastatic breast carcinoma in patients with mammary Paget's disease and underlying cancer is 61.3%, with a 10-year cumulative survival rate of 33%.
