Risk stratification by ultrasound and mammography for screen-detected non-palpable breast cancer in Chinese women.

ABSTRACT:

Background

Mammography (MG) and ultrasound (US) are currently the 'real-world' initial imaging tests for breast cancer in China. Previously, we demonstrated that US and MG detected non-palpable breast cancer (NPBC) had similar survival. This study was performed to validate the hypothesis whether MG+/US- NPBC could be taken as ultra-low risk cancer.

Method

From 2015-2018, 3,113 consecutive patients received biopsy with initial positive screening. Among them, 2,591 US positive patients underwent US-guided biopsy. Meanwhile, 371 MG+/US- patients underwent MG-guided biopsy. Clinical characteristics, treatment and 5-year disease free survival (DFS) and overall survival (OS) were analyzed. Prognostic factors of NPBC were identified.

Results

We identified 419 cases of US+/MG
