Lobular carcinomas in situ display intra-lesion genetic heterogeneity and clonal evolution in the progression to invasive lobular carcinoma.
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.
Conclusions High-risk women with greater than minimal BPE at screening MRI have increased risk of future breast cancer.
CONCLUSIONS: Although a carcinoma within a preexisting benign fibroepithelial tumor is extremely rare, it is important to be aware of the possibility of invasive and metastatic disease. PMID: 29460095 [PubMed - as supplied by publisher]
AbstractPurpose of reviewThe purpose of this review is to describe recent updates in the management of high-risk breast lesions. We review the various high-risk breast lesions and evaluate the collective literature regarding the rates of upgrade to invasive cancer or ductal carcinoma in situ with excisional biopsy as well as the increased risk for future breast cancer development that a diagnosis of a high-risk breast lesion may portend. For those lesions associated with an increased risk of breast cancer, we discuss the appropriate surveillance regimens as well as risk reduction opportunities available to patients.Recent ...
Conclusion Combining DWI, T2WI, and ADC values provides increased accuracy for differentiation between benign and malignant lesions, compared with DCE-MRI. A lower ADC value was associated with a higher histologic grade cancer.
ConclusionsSurgical excision of LN yields a low upgrade rate when careful consideration is given to radiologic/pathologic correlation to exclude cases of discordance. Observation with interval breast imaging is a reasonable alternative for most cases.

CONCLUSIONSIn patients who had an initial diagnosis of atypical hyperplasia or lobular carcinoma in situ on core biopsy, the 7‐year cumulative breast cancer incidence was 9.9%. Most tumors were ipsilateral, stage I, estrogen receptor‐positive, invasive carcinomas. The current data support close clinical and radiologic follow‐up for more than 5 years in this patient population. Cancer 2017. © 2017 American Cancer Society.
This study aimed to evaluate the clinicopathological characteristics of pregnancy-associated breast cancer (PABC) in comparison with non-pregnancy associated breast cancer (non-PABC). METHODS: A total of 344 eligible patients with PABC were identified in the Korean Breast Cancer Society Registry database. PABC was defined as ductal carcinoma in situ, invasive ductal carcinoma, or invasive lobular carcinoma diagnosed during pregnancy or within 1 year after the birth of a child. Patients with non-PABC were selected from the same database using a 1:2 matching method. The matching variables were operation, age, and initial...
