Clinicopathological features of mammary Paget’s disease: a single-center experience in Turkey

Abstract

Background/aim: Paget's disease (PD) of the breast is a very rare presentation of breast malignancy, accounting for 1-3% of all primary breast tumors. We aimed to evaluate and compare the clinicopathological featuresand clinical outcome of PD accompanied by in situ carcinoma and invasive cancer. Materials and Methods:We used the archive of our pathology laboratory retrospectively for age, gender, history of surgery, histopathological findings, treatment modalities and follow-up information. We used the Kaplan-Meier method for survival analysis.Results: There were 46 female patients diagnosed with PD. In 39 (84.7%) patients invasive carcinoma accompanied PD, while 7 (15.3%) patients had ductal carcinoma in situ (DCIS).The median age at diagnosis was 53.5 years. The median follow-up period was 47 months. Of the 39 invasive carcinoma 10 (25.6%) died during the follow-up period. Invasive ductal carcinoma group had a mean overall survival of rate of 57.8 ± 6.6 months. According to univariate analysis only the tumor type was found to impact overall survival (p < 0.001) Conclusions:The current study displayed the tumor type as the only parameter affecting overall survival in the invasive carcinoma group. Although it was not statistically significant, breast cancers accompanied by PD were found to be predominantly advanced stage tumors, high grade, hormon receptor negative and HER2 positive.

The effects of clinicopathological and imaging findings on recurrence and survival in mammary Paget’s disease

“…In our study, we determined these periods to be earlier at 39.4 and 42 months, respectively. Kar et al [ 25 ] found the OS for patients with MPD to be 58±9.5 months (95% CI: 39.2–76.7). While 43 of our patients (87.8%) were alive, six of them died during follow-ups.…”
