Abstract

Abstract: Mucinous breast carcinoma (MBC) carcinoma represents approximately 1–6% of all malignant breast carcinoma and is divided into pure (PMBC) and mixed (MMBC) subtypes. This study presents the comparison of clinical characteristics and treatment results in 70 patients with PMBC and 40 patients with MMBC, treated at a single institution during 25 years. Performed analyses showed that only nodal status was different in both subtypes. Patients with MMBC showed a significantly higher incidence of axillary nodal metastases in comparison to PMBC (25% versus 10%, respectively). Instead, the 10‐year disease‐free survival rate was significant higher in PMBC than MMBC (85.7% versus 65%, p < 0.02, test log rank). Authors own observations and data from literature proved that MMBC should be considered as subtypes of mucinous breast cancer.
