Abstract
Reduction mammoplasty (RM) is one of the most frequently performed surgical procedures. The incidental determination of significant pathologic lesions (SPL), that is precursor and malignant lesions, in RM specimens is rare. The aim of this study was to determine the frequency of SPL in RM specimens, to evaluate the relationship between SPL and clinicopathological factors, and to examine the incidence of invasive breast carcinoma forming in the remaining breast tissue during the postoperative follow-up period developing in patients after RM operation. This retrospective study included 874 females who underwent RM operation between January 2012 and January 2021. Demographic, clinicopathological findings, and preoperative radiological findings were recorded. The patients were followed up after the RM operation in respect of the first occurrence of breast cancer. Invasive carcinoma was determined in 0.2% and SPL in 3.5% in RM. The probability of SPL determination was greater in patients aged ≥ 40 years and with ≥ 4 paraffin blocks (p=0.038, p=0.01, respectively). No statistically significant difference was found between patients with and without SPL in respect of radiological findings (p=0.35). The mean postoperative follow-up period was 53.6 months, and invasive carcinoma was diagnosed during follow-up in 0.2% of all patients (6.9% of the patients with SPL). Age over 40 years and an increased number of sampled blocks were found to be factors increasing the possibility of the determination of precursor and malignant lesions in RM specimens. RM could decrease the risk of the development of breast cancer. This journal requires that authors assign a level of evidence to each article.
