Clinical Trial Summary

In this multicenter study, the goal was to document the excisional biopsy or follow-up results of high risk lesions diagnosed on image guided CNB/VAB, and evaluate the clinical, imaging and histologic features for associated malignancy risk. The possibility of upgrade related to histologic subtype, tissue sampling and other variables was also evaluated.

Description:

This is a retrospective multicentric study that include 1345 patients from 30 centers. Patients who had a diagnosis of high risk lesions (HRL) on image guided core biopsy (tru-cut/vacuum biopsy) were reviewed in a 12 year period (between 2008 and 2020). The lesions included were ADH, LN (ALH/LCIS), papilloma (without or with atypia), RS, and FEA. The patients who managed with an excisional biopsy or having at least 1 year follow-up documentation following the diagnosis of borderline lesion were included in the study. Radiological findings, diameter of lesion (>15 vs <15 mm), needle biopsy type (14-16G vs 9-12G), sampling method and number of samplings (4 and >4 vs <4) were documented. IBM SPSS Version 25.0 statistical package program was used for analysis.
