Background: T1a,bN0 breast cancer is not easily detected. Before mammography became widespread, most cases were discovered only after the development of symptoms. The presence of ductal carcinoma in situ (DCIS) affects the detectability of associated invasive cancer; however, the prognostic value of concomitant DCIS is controversial. This study compared the characteristics of screening-detected and symptom-detected T1a,bN0 breast cancer, and investigated the impact of accompanying DCIS on detection and prognosis...

BACKGROUND: The role of nipple discharge cytology (NDc) in the surgical management of breast cancer patients is unclear. We aimed: (i) to evaluate the effect of malignant NDc on the surgical approach to the nipple-areola complex, and (ii) to verify the association between malignant NDc and nipple malignancy. METHODS: We retrospectively analyzed a case series of 139 patients with NDc who underwent breast surgery. The clinical and histological findings, types of surgery with emphasis on nipple-areola complex amputation, immunohistochemical phenotypes of the carcinomas and measurements of the tumor-nipple distance were recorded...

BACKGROUND: While the roles of hypofractionated (HFxn) radiotherapy and lumpectomy boost in the adjuvant management of invasive breast cancer are supported by the results of clinical trials, randomized data supporting their use for ductal carcinoma in situ (DCIS) are forthcoming. We sought to evaluate current national trends and identify factors associated with HFxn and boost usage using the National Cancer Database. PATIENTS AND METHODS: We queried the National Cancer Database for women diagnosed with DCIS from 2004 to 2014 undergoing external beam radiotherapy after breast conservation surgery...

Increasing numbers of women in the US are getting too little sleep. Inadequate sleep has been associated with impaired metabolic function and endocrine disruption. Sister Study cohort participants (n=50,884), completed baseline and follow-up questionnaires on sleep patterns. Incident breast cancers estrogen receptor (ER) status of the tumor were ascertained from questionnaires and medical records. Cox regression was used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs). Analyses of sleep characteristics reported at the first follow-up interview included only participants who were breast cancer-free at time of follow-up interview...

Breast cancer epidemiological patterns vary in European countries, which present different incidence rates. Data have suggested that the reduction in breast cancer mortality is not only due to the early detection of the disease, but is, in almost equal part, due to screening and to the advances that have been made in molecular medicine and the development of novel therapies. The aim of the present study is to quantify the actual number of cases of breast cancer present in both of the sexes by calculating the prevalence of silent breast cancer in corpses...

A diagnosis of ductal carcinoma in situ (DCIS) at needle biopsy often changes to that of invasive ductal carcinoma as the definitive pathological diagnosis following the surgical procedure. The present study sought to identify the factors associated with invasive disease in cases diagnosed as DCIS on needle biopsy by analyzing (18)F-fluorodeoxyglucose-proton emission tomography (FDG-PET) findings. The present study retrospectively investigated the cases of 24 consecutive patients with primary breast cancer who were preoperatively diagnosed with DCIS by needle biopsy...

PURPOSE: Radiation therapy (RT) after breast-conserving surgery (BCS) for Ductal Carcinoma in Situ (DCIS) halves the risk of local recurrence (LR). The omission of RT is often supported by the paradigm that patients who develop LR can be salvaged with further breast-conserving therapy leading to higher rates of breast preservation and improved quality of life. However, population-based, long-term rates of breast preservation in women treated by upfront BCS ± RT are unknown. METHODS AND MATERIALS: Women diagnosed with pure DCIS from 1994 to 2003 treated with BCS ± RT in Ontario were identified...

Assessment of tumor-infiltrating lymphocytes (TILs) in histopathologic specimens can provide important prognostic information in diverse solid tumor types, and may also be of value in predicting response to treatments. However, implementation as a routine clinical biomarker has not yet been achieved. As successful use of immune checkpoint inhibitors and other forms of immunotherapy become a clinical reality, the need for widely applicable, accessible, and reliable immunooncology biomarkers is clear. In part 1 of this review we briefly discuss the host immune response to tumors and different approaches to TIL assessment...

BACKGROUND: Adjuvant hormonal therapy (HT) reduces breast cancer recurrence risk in estrogen receptor-positive (ER+) ductal carcinoma in situ (DCIS). We assessed national practice patterns and influence of surgery and pathology on HT use in DCIS. METHODS: Data on DCIS patients diagnosed from 2004 to 2014 were extracted from the National Cancer Database, and patients were classified according to ER status and whether HT was received. Factors associated with HT use were assessed using Chi square tests for univariate analysis and logistic regression for multivariate analysis...

BACKGROUND: Overexpression of human epidermal growth factor 2 (HER2) in invasive breast cancer (IBC) is an independent poor prognostic factor. However, the significance of HER2 overexpression in ductal carcinoma in situ (DCIS) is not well defined. The current study assessed the correlation of HER2(+) DCIS with the rate of upstaging to IBC on the final pathology. METHODS: The study retrospectively analyzed patients with the diagnosis of DCIS on core needle biopsy (CNB) at the authors' institution from 2009 to 2016...
