Clinical management of microinvasive breast cancer (Tmic) remains controversial. Although metastases are infrequent in Tmic carcinoma patients, surgical treatment typically includes lymph node sampling. The objective of this study was to determine the rate and predictors of lymph node metastases, recurrence, and survival in a large series of Tmic breast carcinomas. Consecutive cases of Tmic were identified within our health care system from 2001 to 2015. We reviewed results of lymph node sampling and other pathologic factors including hormone receptor/HER2 status, associated in situ tumor size/grade, margin status, number of invasive foci, surgical/adjuvant therapies, and recurrence/survival outcomes...

BACKGROUND: Tumour-infiltrating lymphocytes (TILs) have been demonstrated to significantly influence prognosis and response to therapy of invasive breast cancer (IBC). Thus, it has been suggested that TIL density or/and immunophenotype could serve as biomarkers for selection of IBC patients for immunotherapy. However, much less is known about significance of TILs in breast ductal carcinoma in situ (DCIS). METHODS: We retrospectively investigated TIL density and immunophenotype in 96 pure DCIS and 35 microinvasive carcinomas (miCa)...

PURPOSE: Controversy surrounds management of lobular neoplasia (LN), [atypical lobular hyperplasia (ALH) or lobular carcinoma in situ (LCIS)], diagnosed on core needle biopsy (CNB). Retrospective series of pure ALH and LCIS reported "upgrade" rate to DCIS or invasive cancer in 0-40%. Few reports document radiologic/pathologic correlation to exclude cases of discordance that are the likely source of most upgrades, and there is minimal data on outcomes with follow-up imaging and clinical surveillance...

BACKGROUND: Ductal carcinoma in situ (DCIS) is a neoplastic proliferation of epithelial cells which is confined within the basement membrane of the mammary ductal-lobular system. It is of interest to determine to what extent the potential to metastasize increases for DCIS patients when the basement membrane is breached (i.e. microinvasion is present). METHODS: We retrieved the records of 525,395 women who had either first primary DCIS or small (≤ 2.0 cm) node-negative invasive breast cancer in the Surveillance, Epidemiology and End Results (SEER) registries database (1990-2013)...

INTRODUCTION: Pleomorphic lobular carcinoma in situ (PLCIS) is a variant of LCIS with high-grade morphologic features. The number of case series studying PLCIS is limited, and clinical management of patients with PLCIS is controversial. We report a breast core biopsy (BCBx) series of PLCIS. MATERIALS AND METHODS: We reviewed 37 cases of PLCIS with or without microinvasion diagnosed by BCBx. PLCIS was defined as dyscohesive cells showing acinar expansion and loss of immunohistochemical membranous expression of e-cadherin or beta-catenin with nuclear pleomorphism with at least 2- to 3-fold variation in nuclear size, membrane irregularities, and variably prominent nucleoli...

Breast cancer is the leading cause of cancer death in women younger than 40 years. Triple-negative breast cancer (TNBC) and human epidermal growth factor receptor-2 (HER2) positive subtypes have a particularly poor prognosis in this age group. The purpose of this study was to compare rates of recurrence among breast cancer subtypes in young patients treated with modern adjuvant systemic therapy. A retrospective review of breast cancer patients managed at a major academic breast center between May 2000 and November 2014 was performed...

PURPOSE: The natural history of pleomorphic lobular carcinoma in situ (PLCIS) remains largely unknown. METHODS: A pathology database search (1995-2012) was performed to identify patients diagnosed with an LCIS variant. Patients with synchronous breast cancer and/or no evidence of pleomorphism were excluded. Original slides were re-evaluated by three pathologists to identify a consensus cohort of PLCIS. Borderline lesions with focal atypia were classified as LCIS with pleomorphic features (LCIS-PF)...

Importance: The use of a radiotherapy (RT) boost to the tumor bed after whole-breast RT (WBRT) for ductal carcinoma in situ (DCIS) is largely extrapolated from invasive cancer data, but robust evidence specific to DCIS is lacking. Objective: To compare ipsilateral breast tumor recurrence (IBTR) in women with DCIS treated with vs without the RT boost after breast-conserving surgery and WBRT. Design, Setting, and Participants: This retrospective analysis pooled deidentified patient-level data from 10 academic institutions in the United States, Canada, and France from January 1, 1980, through December 31, 2010...

BACKGROUND: It is desirable to decrease the underestimation rate of invasion in cases diagnosed as ductal carcinoma in situ (DCIS) in breast core needle biopsy (CNB) in order to determine the appropriate candidates for axillary staging. The objective of this study is to identify the predictors of invasion in histology. METHODS AND RESULTS: Consecutive 92 CNB's were retrospectively evaluated. The upstaging rate was 47.8% after surgery. Among all the evaluated parameters, high nuclear grade, single architectural pattern, marked periductal lymphocytic infiltration, partial myoepithelial loss and the presence of foci suspicious of microinvasion were the significant predictors of invasion (two tailed p values 0...

We report a case of recurrent breast cancer with involvement of the right adrenal grand, which was resected using laparoscopic surgery. The patient was a 41-year-old woman who underwent duct-lobular segmentectomy for ductal carcinoma in situ. Histopathology showed microinvasion, and tested positive for ER and PR, but negative for HER2, so we applied radiation to the remaining breast and administered tamoxifen. After 9 months, local recurrence was detected and quadrantectomy with axillary lymph node dissection was performed...

We report a case of breast cancer with microinvasion and lymph node metastasis. The patient was a 72-year-old woman who had spontaneous nipple discharge from her left breast. There was no detectable lesion on mammographyor duct endoscopy. Ultrasonography showed a low echoic lesion, 23×15mm in diameter, in the CD area of her left breast. Contrastenhanced MRI showed a high intensityarea, 25mm in diameter, in her left breast, so microdochectomywas performed. The histopathological diagnosis was invasive ductal carcinoma(invasion of 2mm)and the surgical margin was positive...

BACKGROUND: Papillary carcinoma (PC) of the breast represents ∼0.5% of all newly diagnosed cases of breast cancer and usually has an indolent course. The current data suggest lack of a consensus in the surgical management of this disease. Because patients can occasionally develop metastatic disease, sentinel lymph node (SLN) biopsy is often performed during surgery. MATERIALS AND METHODS: In the present study, we retrospectively evaluated the histologic characteristics of 99 cases of PC with or without associated frank invasive carcinoma, including 43 encapsulated or intracystic PCs, 24 solid PCs, and 32 intraductal PCs, and correlated these with the incidence of nodal metastasis...

BACKGROUND: Ductal carcinoma in situ with microinvasion (DCIS-Mi) generally has favorable prognosis, but the long-term outcomes of DCIS-Mi and the biologic evolution from ductal carcinoma in situ (DCIS), DCIS-Mi, to DCIS with T1a breast cancer (DCIS-T1a) has not been specified. The aim of our study was to explore the biological and prognostic features of DCIS-Mi, compared with pure DCIS and DCIS-T1a. RESULTS: After a median follow-up of 31 months, the 3-year estimated disease free survival(DFS) rate of DCIS-Mi patients was significantly lower than that of pure DCIS patients (89...
