This retrospective study was conducted in the Shiraz breast clinic, which is a BC referral center for central and southern Iran. This study was conducted and included patients from June 1997 up to November 2018 using data from the Shiraz Breast Cancer Registry (SBCR) which includes data from 8000 plus patients with BC [8]. The registry includes data on socioeconomic status, baseline characteristics, patients’ clinical history, physical examination, imaging, disease course, and prognosis among individuals diagnosed with BC.
Women who had both FS and permanent pathology reports of any age were included in this report. All patients had a previous pathological diagnosis. Considering the goal of the study, all male BC patients were excluded. Furthermore, all patients with missing data on frozen or permanent pathology were excluded from the study.
