Abstract
Background
Over the last decade, rates of risk-reducing prophylactic mastectomy (PM) have risen
dramatically. A topic of debate regarding the procedure is whether to use sentinel
lymph node biopsy (SLNB) at the time of PM and what factors might predict for such
need. In order to assess the rate of identifying presence of occult invasive breast
cancer in the PM specimen, we performed a retrospective review of the pathology findings
from a single-surgeon case-series of PM.
Methods
Patients undergoing PM between January 2013 and June 2019 at Orlando Health Cancer
Institute were identified for a retrospective chart review. Demographic, clinical,
and histopathological data from the surgical procedure were collected and analyzed
for the incidence of occult invasive breast cancer in the PM specimen.
Results
A total of 146 consecutive patients with PM were identified; 120 (82.2%) underwent
contralateral PM (CPM) and 26 (17.8%) underwent bilateral PM (BPM). Final pathology
of the 172 PM specimens identified 4 (3.3%) with lobular carcinoma in situ, 3 (2.5%)
with atypical ductal hyperplasia, and 2 (1.7%) with atypical lobular hyperplasia and
2 (1.7%) with intraductal papilloma. No invasive malignancy was detected in any of
the 172 PM specimens.
Conclusions: The absence of occult invasive carcinoma in 172 consecutive PM specimens
suggests a limited clinical utility in routinely performing SLNB in this setting.
This study also suggests that use of preoperative breast MRI imaging could offer a
potential non-invasive tool to detect occult malignancy and select patients who can
safely undergo omission of SLNB at the time of PM.
