Unveiling the Clinical Path of Microinvasive Breast Cancer: A Comparative Study With Tis-T1 Breast Cancer.

ABSTRACT:

Purpose

The prognosis of microinvasive breast cancer (MIBC) is controversial, with a high reported rate of local recurrence (LR). This study aimed to evaluate the characteristics, treatments, and prognosis of patients with MIBC compared to those with carcinoma in situ (CIS) or early invasive cancer.

Methods

Patients who diagnosed with CIS or stage I breast cancer were retrospectively enrolled. Using the Kaplan-Meier method, local recurrence-free survival (LRFS), systemic recurrence-free survival (SRFS), and cancer-specific survival (CSS) were compared according to T stage. The prognostic factors associated with LRFS were identified using the Cox proportional hazards model.

Results

According to T stage, 517 (21.6%), 200 (8.4%), 207 (8.7%), 363 (15.2%), and 1101 (46.1%)
