Abstract

The present study aimed to determine the difference between the clinical tumor stage (T stage) based on pre‑operative ultrasound and the histopathological T stage subsequent to surgery in vacuum‑assisted breast biopsy (VABB)‑diagnosed breast cancer. Tumor sizes measured ultrasonography (USG) and histologically were retrospectively calculated and analyzed using paired t‑tests in 209 patients diagnosed with breast cancer using VABB. The patients were classified into two groups, consisting of breast imaging reporting and data system (BI‑RADS) category 4a or below, who underwent complete resection by VABB, and BI‑RADS category 4b or above, who underwent incisional biopsy by VABB. The histopathological tumor size was found to be smaller compared with the USG‑determined size in 92.3% of pT1a, 75.5% of pT1b, 44.2% of pT1c, 47.7% of pT2 and 0% of pT3 cases. Furthermore, the histopathological tumor size was smaller compared with the USG‑determined size in 62.8% of cases classified as BI‑RADS category 3‑4a and in 53.7% of cases classified as BI‑RADS category 4b‑5. The smaller the primary tumor at the time of diagnosis by VABB, the higher the likelihood of pathological underestimation on post‑operative histopathological assessment compared to pre‑operative USG.
