The value of preoperative mammograms in nononcologic breast surgery

Current practices of plastic surgeons at King Abdulaziz University Hospital in requesting breast imaging studies prior to non-oncological breast surgeries

Background

In the context of the high incidence of breast cancer and the high frequency of breast cosmetic surgeries, malignant and/or premalignant lesions are frequently detected incidentally in postoperative histopathology specimens. The current literature does not provide clear practice guidelines for the use of preoperative imaging prior to non-oncological breast surgeries.

Objectives

In this study, we aimed to determine the current practices of plastic surgeons at King Abdulaziz University Hospital (KAUH) and their use of preoperative breast imaging before non-oncological breast surgeries.

Design

Non-intervention/ retrospective record review.

Settings

Department of Radiology at King Abdulaziz University Hospital (KAUH).

Methods

In 08/06/2017 at King Abdulaziz University Hospital, we conducted a single-center, retrospective chart review of the medical files of candidates for non-oncological breast surgery in order to examine preoperative imaging requests by plastic surgeons in the period 01/01/2013 to 08/06/2017.

Main outcome measures

The practice of plastic surgeons at KAUH in requesting preoperative imaging prior non-oncological breast surgeries.

Sample size

104 patients.

Results

We found that, in the period 2013 to 2017, 104 women who underwent non-oncological breast surgeries were evaluated for recent preoperative breast imaging. Only 37 patients (35.6%) were found to have had preoperative imaging, and only less than one fifth (19.4%) of those 37 patients had abnormal preoperative imaging results, all of which were negative for malignancy.

Conclusions

Although the yield of malignancy on preoperative breast imaging was zero in women seeking non-oncological breast surgeries at KAUH, we recommend the establishment of unified practice guidelines to be followed by plastic surgeons for better postoperative screening in different risk groups.

Limitations

Lack of follow up of patients postoperatively for any development of malignancy.

Occult breast carcinoma in reduction mammaplasty specimens: 14-year experience

Reduction mammaplasty is commonly performed for bilateral macromastia, congenital asymmetry, or as a contralateral symmetry procedure in breast reconstruction following mastectomy for cancer. Occult carcinoma has been detected in 0.06 percent to 0.4 percent of breast reduction specimens. The purpose of this study was to examine the incidence of breast cancer in breast reductions performed in one institution over a 14-year period. The authors reviewed their experience with 800 reduction mammaplasties performed between 1988 and 2001. Six cancers were detected (0.8 percent). Of these cancers, three were invasive (0.4 percent) and three were ductal carcinoma in situ (0.4 percent). Stratified by indication for surgery, there was a trend toward higher detection rates in the reconstruction group (1.2 percent) compared with the macromastia (0.7 percent) or congenital asymmetry (0 percent) groups. Mammography was performed preoperatively in these patients and all results were negative for masses or suspicious microcalcification. Pathological diagnosis was guided by gross specimen evaluation in two patients and specimen radiography in one patient. Reduction mammaplasty has a small but definite risk of finding cancer in the resection specimen.
