Atypical Lobular Hyperplasia

The management of atypical lobular hyperplasia (ALH) on core biopsy remains controversial. The upstaging rates after surgical excision vary. We reviewed our upgrade rates and use of chemoprevention for ALH. Patients were identified through our pathology database for ALH from 2006 to 2013. Patients were included in the study that had a diagnosis only of ALH on core needle biopsy. Tumor and patient characteristics and final pathology were analyzed. ALH was identified in 56 patients since 2006. Sixteen patients met the inclusion criteria. All the patients underwent surgical excision. Final pathology of the excised specimens confirmed ALH in 62 per cent (n = 11). Two cases contained lobular carcinoma in situ. The upgrade rate on excisional biopsy was 18.75 per cent (n = 3) to invasive cancer. Chemopreventative treatment was taken by 44 per cent of the patients. After a mean follow-up of three years, none of the patients who received chemoprevention developed breast cancer. One patient who refused tamoxifen developed breast cancer. This is one of the few studies to examine the current treatment of ALH. We noted a significant upstaging rate after excision. We recommend women to undergo surgical excision. Patients should also consider chemoprevention to reduce their risk for developing breast cancer.

The treatment of breast cancer associated with lobular neoplasia detected on core needle biopsy (CNB) remains controversial. The purpose of this study was to review the prevalence of lobular neoplasia in CNB specimens and to correlate CNB pathology to final surgical pathology. Patients with lobular neoplasia were included for analysis in this retrospective review. Patients with concomitant malignant or atypical lesions were excluded. Method of initial diagnosis, clinical history, pathology results, and follow-up data were then analyzed. From January 1994 to December 2005, 5257 CNBs were performed at our tertiary level medical facility. Of patients with lobular neoplasia, 42 of 50 (84%) patients had atypical lobular hyperplasia, whereas 8 (16%) patients were diagnosed with lobular carcinoma in situ on CNB specimens. There were no associated malignancies in 21 patients who underwent immediate surgical excision. Of those patients who were serially followed, four developed malignancies at an average of 73 months after the sentinel diagnosis. Three of the four (75%) malignancies occurred in the ipsilateral breast. Patients with a diagnosis of lobular neoplasia by CNB should not routinely undergo an open surgical biopsy. Lobular neoplasia should only be considered a risk marker for future invasive breast cancer.

Context.— The management of lobular neoplasia (LN) found on core biopsy is controversial and ranges from obligatory surgical excision to clinical/imaging observation. Objective.— To determine if in cases of core needle biopsy yielding LN, quantification of normal and diseased terminal ductal lobular units (TDLUs) can predict which cases require surgical excision and which can be safely followed. A secondary goal is to assess whether the concordance or discordance of core biopsy results, determined by rigorous radiologic-pathologic correlation, can predict for upgrade to malignancy at excision. Design.— In this retrospective study, 79 specimens from 78 women who underwent image-guided core needle biopsies between 2005 and 2012 yielding LN were evaluated for total number of TDLUs and total number and percentage of TDLUs involved by LN. Additionally, radiologic-pathologic correlation was performed to assess concordance or discordance. All were correlated with the results of surgical excisional biopsy or imaging/clinical follow-up. Results.— There were 5 upgrades to malignancy. There was no association between upgrade to malignancy and any of the 3 TDLU variables evaluated, including total TDLUs in the specimen (P = .42), total abnormal TDLUs (P = .56), and percent of TDLUs that are abnormal (P = .07). Kendall rank correlation demonstrated a correlation between discordance and upgrade to cancer at surgery that was statistically significant (τb = −0.394, P < .001). Conclusions.— Quantifying total TDLU and those involved by LN on core biopsy will not aid in triaging patients to surgery or observation. Assiduous radiologic-pathologic correlation to determine lesion concordance/discordance can predict those patients who would benefit from surgical excision.

Abnormal Pathology

Columnar cell lesion with atypia (CCLA) is a newly recognized pathologic entity seen in breast specimens. The breast cancer risk associated with this finding is unclear, although CCLA had been found adjacent to both in situ and invasive carcinomas, but the incidence is unknown. Breast specimens from patients with a columnar cell lesion were reviewed by a pathologist for atypia. Twenty-one specimens with CCLA were identified [core biopsy (8), excisional biopsy (11), and simple mastectomy (2)]. Six of eight specimens with CCLA on core had adjacent abnormal pathology: infiltrating ductal carcinoma (IDC)/lobular carcinoma in situ (LCIS) (1), ductal carcinoma in situ (DCIS)/LCIS (1), DCIS (1), LCIS (1), and papillomatosis (2). Five of 11 specimens with CCLA on excisional biopsy had adjacent abnormal pathology: IDC (3), DCIS/LCIS (1), and atypical ductal hyperplasia/papilloma (1). Two of two simple mastectomy specimens had CCLA associated with IDC (1) and DCIS (1). Overall, abnormal pathology was found adjacent to CCLA in 62 per cent of specimens (13/21). Breast pathologic specimens containing a columnar cell lesion should be carefully examined for atypia. Surgical excision is warranted for CCLA found on core biopsy. The future risk of breast cancer based on the finding of CCLA alone requires further investigation.

Her 2

Accurate assessment of HER-2/neu gene status in breast cancer patients has important prognostic and therapeutic implications. Overexpression/gene amplification of HER-2 is associated with a more aggressive clinical course and eligibility for targeted therapy with trastuzumab. A variety of immunohistochemical (IHC) antibodies and in situ hybridisation (ISH) methods have been employed to assess HER-2 status. SP3 is a rabbit monoclonal antibody that has been shown to have a high level of agreement with other anti-HER-2 antibodies and ISH methods. We assessed HER-2 status by SP3 and HercepTest IHC stains and by fluorescence in situ hybridisation (FISH) on invasive breast carcinomas from paired needle core biopsy and excisional biopsy specimens from 100 patients. We compared the two antibodies with respect to concordance rates with FISH, concordance rates between samples of the same tumour, and sensitivity and specificity using FISH as the reference test. Concordance between SP3 and FISH in needle core biopsy and excisional biopsy specimens was 96% (95% CI 91.9% to 99.7%) (κ=0.89 (95% CI 0.73 to 1.00)) and 97% (95% CI 90.3% to 99.3%) (κ=0.84 (95% CI 0.66 to 1.00)), respectively. Sensitivity and specificity of SP3 for detecting HER-2 overexpression/gene amplification were 78.3% and 100%, respectively, in needle core biopsy and excisional biopsy specimens. Concordance between SP3 results assessed on the needle core biopsy and excisional biopsy was 89% (95% CI 81.2% to 94.4%) (κ=0.62 (95% CI 0.42 to 0.82)). Concordance between SP3 and HercepTest antibodies, after excluding 2+ cases, was 97.6% (95% CI 94.0% to 99.3%) (κ=0.88 (95% CI 0.77 to 1.00)). SP3 is a reliable alternative to HercepTest in evaluating HER-2 status in breast cancer patients. Like other anti-HER-2 antibodies, SP3 may serve as a diagnostic tool in breast pathology and has potential utility as an IHC biomarker in non-mammary malignancies.

75 Background: Lobular neoplasia (LN) is a continuum of rare, noninvasive lesions of the breast including lobular carcinoma in situ and atypical lobular hyperplasia. Current management is controversial and often includes excisional biopsy in women diagnosed with LN on percutaneous core biopsy (PCB) to exclude an occult malignancy. This strategy is based on retrospective data in women undergoing selective excisions. We performed routine excision of all lesions diagnosed as LN in our institution in order to ascertain a more accurate assessment of pathologic upgrade. Methods: Retrospective review of all prospectively collected cases of LN treated in a single institution from 2007-2010. Excisional biopsies were performed in all cases of LN excepting one (patient declined). Histologic findings of excisional biopsies were reviewed to assess the rate of pathologic upgrade. Results: Of the 2,289 PCBs performed during the study period, LN was found in 23 cases (1.0%). Twenty two (0.96%) cases proceeded to excisional biopsy. On final pathology, malignancy was found in 4 patients (18%). Two of 22 (9%) women were upgraded to ductal carcinoma in situ (DCIS) (both intermediate grade with foci of <1mm and 4mm) and 2/22 (9%) women were diagnosed with invasive lobular carcinoma. Conclusions: While 18% of women in our series had upgraded pathology at the time of excisional biopsy, we support selective rather than routine excisional biopsy. One of the invasive diagnoses was an incidental finding unrelated to the microcalcifications for which biopsy was initially performed. In the second case of invasive disease, the upgraded lesion was a mass identified on MRI performed for surgical planning in a woman already diagnosed with breast cancer. In both cases of DCIS, the area of malignancy was small (<1mm and 4mm) and of uncertain clinical significance. Based on these findings, we do not recommend routine excision of all LN identified on PCB. Cases in which the lesion is associated with a radiographic mass and/or is identified in a breast with a synchronous malignancy do warrant excisional biopsy. Patients without these high risk features can be counseled on the risks of malignancy and given the option of observation with close follow up.
