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...

BACKGROUND: Several studies investigated the correlation between the intensity of fluorodeoxyglucose (FDG) uptake and some histological and biological characteristics in breast cancer. Ductal carcinoma in situ (DCIS) is generally thought to be a precursor lesion of invasive breast cancer. The aim of this study was to assess the correlation between FDG uptake values on positron emission tomography/computed tomography (PET/CT) with histological and biological prognostic factors in DCIS and ductal carcinoma in situ with microinvasion (DCIS-Mi)...

We report a case of microinvasive carcinoma of the breast cytologically diagnosed as ductal carcinoma - in situ in an 80-year-old lady with a breast lump. Extensive sampling of mastectomy specimen showed ductal carcinoma in situ (DCIS). Many ducts showed stromal reaction - periductal sclerosis and lymphocytic infiltration-features suggestive of microinvasion. However, no definite invasion was noted histologically. Immunohistochemical study highlighted the microinvasive foci.

BACKGROUND: No consensus exists for clear margins for breast-conserving surgery for pure ductal carcinoma in situ (DCIS). We examined the implications of applying a "no ink on tumor" standard for pure DCIS by correlating clear margin width with rates of residual disease. METHODS: Lumpectomies with complete shaved cavity margins (SCMs) for pure DCIS at our institution from 2004 to 2007 were reviewed and patients with microinvasive cancer or multifocal disease requiring multiple wires excluded...

A 48-year-old woman had a left breast mass identified during routine breast cancer screening. The mammogram showed pleomorphic-segmental microcalcifications in the mediolateral-oblique view of the left breast. Ultrasonography showed a hypoechoic mass approximately 3.7 cm in diameter with multiple calcifications. Contrast-enhanced magnetic resonance imaging of the breast showed non-mass like enhancement of approximately 4 cm in diameter in the C area of the left breast. She was diagnosed with glycogen-rich clear cell carcinoma (GRCC) by ultrasound-guided vacuum-assisted biopsy...

AIMS: While cancer immunity is involved in tumour progression from the very early stage, no detailed study has been reported on the relationship between 'early-stage' breast cancer and tumour-infiltrating lymphocytes (TILs). We focused on microinvasive carcinoma to investigate the relationship between histological tumour factors and immunity in 'early' breast cancer. METHODS: Of 2593 resected breast carcinomas, 46 microinvasive carcinomas (1.8%) were included. The relationships between tumour characteristics (invasive form, grade, comedo, subtype) and immunological characteristics (TIL, healing) were examined...

Microinvasion is the smallest morphologically identifiable stage of invasion. Its presence and distinction from in situ carcinoma may have therapeutic implications, and clinical staging also requires the recognition of this phenomenon. Microinvasion is established on the basis of several morphological criteria, which may be difficult and not perfectly reproducible among pathologists. The aim of this study was to assess the consistency of diagnosing microinvasion in the breast on traditional haematoxylin and eosin (HE) stained slides and to evaluate whether immunohistochemistry (IHC) for myoepithelial markers could improve this...
