Clinicopathological characteristics and prognostic factors of invasive micropapillary carcinoma of the breast.

ABSTRACT:

Purpose

To evaluate the clinicopathological characteristics of breast invasive micropapillary carcinoma (IMPC) and identify factors associated with recurrence and metastasis.

Methods

The study retrospectively analyzed 401 cases of breast IMPC diagnosed between 2017 and 2021. The primary endpoint was recurrence and metastasis-free survival (RMFS). Secondary endpoints included locoregional recurrence-free survival (LRRFS) and distant metastasis-free survival (DMFS). Survival was estimated using the Kaplan-Meier method and compared with the log-rank test. Univariable and multivariable Cox regression analyses were performed to identify prognostic factors. Continuous variables were categorized using maximum log-rank statistics to optimize group stratification.
