Reduction mammaplasty in patients with history of breast cancer : The incidence of occult cancer and high-risk lesions

Introduction: Contralateral reduction mammaplasty is regularly included in the treatment of breast cancer patients. We analyzed the incidence of occult breast cancer and high-risk lesions in reduction mammaplasty specimens of women with previous breast cancer. We also analyzed if timing of reduction mammaplasty in relation to oncological treatment influenced the incidence of abnormal findings, and compared if patients with abnormal contralateral histopathology differed from the study population in terms of demographics. Materials and methods: The study consisted of 329 breast cancer patients, who underwent symmetrizing reduction mammaplasty between 1/2007 and 12/2011. The data was retrospectively analyzed for demographics, operative and histopathology reports, oncological treatment, and postoperative follow-up. Results: Reduction mammaplasty specimens revealed abnormal findings in 68 (21.5%) patients. High-risk lesions (ADH, ALH, and LCIS) were revealed in 37 (11.7%), and cancer in six (1.9%) patients. Abnormal histopathology correlated with higher age (p = 0.0053), heavier specimen (p = 0.0491), and with no previous breast surgery (p <0.001). Abnormal histopathological findings were more frequent in patients with reduction mammaplasty performed prior to oncological treatment (p <0.001), and in patients with immediate reconstruction (p = 0.0064). Conclusion: The incidences of malignant and high-risk lesions are doubled compared to patients without prior breast cancer. Patients with abnormal histopathology cannot be preoperatively identified based on demographics. If reduction mammaplasty is performed before oncological treatment, the incidence of abnormal findings is higher. In the light of our results, contralateral reduction mammaplasty with histopathological evaluation in breast cancer patients offers a sophisticated tool to catch those patients whose contralateral breast needs increased attention.

Breast Cancer Detection by Preoperative Imaging in Reduction Mammaplasty Patients : A Single Center Study of 918 Patients

Background The role of preoperative imaging and the usability of different imaging modalities is highly variable and controversial in reduction mammaplasty patients. Our study describes the imaging process in a single center in regard to modality selection, age and timing, and of the association between imaging and histopathological findings in reduction mammaplasty specimens. Methods Nine hundred eighteen women, who underwent reduction mammaplasty during 1.1.2007-31.12.2011, were retrospectively reviewed for demographics, preoperative imaging, further preoperative examinations, and pathology reports. Results Preoperative imaging had been conducted for 89.2% (n = 819) of the patients. In 49 (6.0%) patients, suspicious preoperative imaging led to further examinations revealing 2 high-risk lesions (atypical ductal hyperplasia (ADH), lobular carcinoma in situ (LCIS)), and 2 cancers preoperatively. Postoperatively abnormal histopathology specimens were revealed in 88 (10.4%) patients. The incidence of high-risk lesions was 5.5% (n = 47), and the incidence of cancer was 1.2% (n = 10). Preoperative imaging was normal (BI-RADS 1 and BI-RADS 2) in 80.8% of these patients. The sensitivity of the preoperative imaging for cancer detection was 20.0%, and the specificity was 100.0%. Conclusions Preoperative imaging and further examinations do not sufficiently detect malignant or cancer risk-increasing findings. Therefore, histopathological analysis of reduction mammaplasty specimens seems mandatory.Peer reviewe

Should we routinely analyze reduction mammaplasty specimens?

Background: Reduction mammaplasty is one of the most common plastic surgery procedures. Preoperative imaging and histopathology protocols vary among countries and institutions. We aimed to analyze the incidence of occult breast cancer and high-risk lesions in reduction mammaplasty specimens. We also analyzed whether patients with abnormal histopathology differed from the study population in terms of demographics. Patients and methods: In total, 918 women who underwent reduction mammaplasty from January 2007 to December 2011 were retrospectively reviewed for demographics, preoperative imaging, further preoperative examinations, pathology reports, and postoperative follow-up. Results: Abnormal histopathological findings were revealed in 88 (10%) patients with a mean age of 49.5 +/- 10.2 years. The incidence of breast cancer was 1.2%, and the incidence of high-risk lesions (atypical ductal and lobular hyperplasia and lobular carcinoma in situ) was 5.5%. Age and specimen weights were significantly higher in patients with abnormal histopathology. Eighty-one percent of patients with abnormal histopathology had normal preoperative imaging revealing two high-risk and two cancer findings. Two patients developed breast cancer in the same breast in which the high-risk lesion was originally detected. Conclusion: Women with abnormal histopathology cannot be sufficiently detected preoperatively. Therefore, histopathological analysis of reduction mammaplasty specimens seems mandatory. Reduction mammaplasty combined with subsequent histopathological examination offers a sufficient chance of detecting cancer and risk-increasing lesions that merits the cost of histopathology.
