Pathologic Evaluation of Breast Tissue From Transmasculine Individuals Undergoing Gender-Affirming Chest Masculinization.
CONCLUSIONS.—: Our study demonstrates that we handle transmasculine mastectomy specimens by examining 2.8 times more slides on average than for RMs, with a 2.5 times lower rate of significant pathologic findings. Prior family history of breast cancer or the use of androgen therapy before surgery in gender-affirming individuals did not increase the risk of identifying significant breast lesions. We recommend submitting 4 tissue blocks per mastectomy for individuals undergoing gender-affirming breast surgery. PMID: 31816268 [PubMed - as supplied by publisher]
Conclusion: The findings of this study are comparable to results in the literature on OPS and demonstrate that OPS is an attractive alternative to standard lumpectomy for Canadian general surgeons who treat breast cancer. PMID: 31995336 [PubMed - indexed for MEDLINE]
ConclusionsBreast cancer risk among women with LCIS is impacted by breast density. These results aid in personalizing risk assessment among women with LCIS and highlight the importance of chemoprevention counseling for risk reduction.
AbstractManagement of classic lobular neoplasia (cLN) diagnosed on core needle biopsy (CNB) is controversial. Our aim in this study was to review cases of cLN diagnosed on CNB to determine the rate and risk factors of an upgrade to ductal carcinoma in situ (DCIS) or invasive carcinoma on excision. All breast CNBs with a diagnosis of atypical lobular hyperplasia (ALH) or classic lobular carcinoma in situ (cLCIS) from three different institutions within a single health care system between 2013 and 2018 were retrieved. Cases with any additional high-risk lesions in the same CNB or discordant radiological-pathological correlat...
Abstract Breast cancer is the most prevalent malignant tumor and main oncologic cause of mortality in women. Although most diagnosis of breast pathology is accomplished using hematoxylin and eosin stained sections, some cases require immunohistochemistry for proper evaluation. We investigated the latter cases including distinctions between ductal and lobular carcinoma, in situ and invasive carcinoma, typical ductal hyperplasia and atypical ductal hyperplasia/ductal carcinoma in situ, papillary and spindle cell lesion assessment, metastasis evaluation, and assessment of prognostic and therapy markers. E-cadherin is...
Conclusions: Immediate reconstruction for unilateral mastectomy and contralateral prophylactic mastectomy have similar complication risk profiles, among patients as a whole and between individual breasts. These findings contribute to our understanding of the clinical impact prophylactic mastectomy and reconstruction may have on optimizing the counseling among extirpative surgeons, reconstructive surgeons, and patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
AbstractPurposeIncrease in in situ breast cancer (BCIS) incidence has been reported across Europe and the USA. However, little is known about the trends in BCIS incidence in regions without population-based mammographic screening programs. We set out to investigate these trends in Zurich, Switzerland, where only opportunistic mammographic screening exists.MethodsData from 989 women diagnosed with a primary BCIS between 2003 and 2014 were used in our analyses. Age-standardized incidence rates per 100,000 person-years (ASR) were computed per year. Additional analyses by BCIS subtype, by age group at diagnosis and by incidenc...
ConclusionsHigh-risk women with greater than minimal BPE at screening MRI have increased risk of future breast cancer.
CONCLUSIONS: Our findings support the contention that LCIS has a repertoire of somatic genetic alterations similar to that of ILCs, and likely constitutes a non-obligate precursor of breast cancer. Intra-lesion genetic heterogeneity is observed in LCIS and should be considered in studies aiming to develop biomarkers of progression from LCIS to more advanced lesions.

CONCLUSION: We conclude that the upgrade rate for high-risk lesions at MRI-VAB at surgical excision is low. Surgical excision is warranted for ADH and combined ALH-LCIS lesions. For other lesions, a multidisciplinary approach to decide on personalized management may be appropriate. Advancesin knowledge: Surgical excision is warranted for ADH lesions and combined ALH-LCIS lesions identified at breast MRI-VAB. A multidisciplinary approach to patient management of other high-risk lesions may be appropriate. PMID: 29947265 [PubMed - as supplied by publisher]
Conclusions: Oncoplastic breast reductions allow wide resections with free margins and can be used for large cancers as an alternative to mastectomy.
