Germline mutations in BRCA1 and BRCA2 account for approximately 50% of inherited breast and ovarian cancers. Three founder mutations in BRCA1/2 have been reported in Colombia, but the pattern of mutations in other cancer susceptibility genes is unknown. This study describes the frequency and type of germline mutations in hereditary breast and/or ovarian cancer genes in a referral cancer center in Colombia. Eighty-five women referred to the oncogenetics unit of the Instituto de Cancerologia Las Americas in Medellin (Colombia), meeting testing criteria for hereditary breast and ovarian cancer syndrome (NCCN 2015), who had germline testing with a commercial 25-gene hereditary cancer panel, were included in the analysis...

PURPOSE: Identification of clinicopathological factors predicting for a locoregional recurrence (LRR) after neoadjuvant chemotherapy (NAC) could help to decide on the optimal locoregional radiotherapy. The objective of this trial is to identify those factors in the context of a phase III trial (European Organisation for Research and Treatment of Cancer 10994). METHODS: Patients received NAC followed by surgery with or without radiotherapy. Radiotherapy was administered according to pre-specified guidelines...

PURPOSE: Exercise is a demonstrated, therapeutic strategy for cancer survivors to minimize many treatment-induced side effects and may decrease risk of recurrence. Nonetheless, structured programs that combine exercise and education are not yet standardized within cancer care. The Health, Exercise, Active Living, Therapeutic lifestyle (HEALTh) program is a clinical exercise program based on the established cardiac rehabilitation model, but customized for female breast cancer survivors...

In a previous study, we detected a significant association between phosphoserine aminotransferase 1 (PSAT1) hyper-methylation and mRNA levels to outcome to tamoxifen treatment in recurrent disease. We here aimed to study the association of PSAT1 protein levels to outcome upon tamoxifen treatment and to obtain more insight in its role in tamoxifen resistance. A cohort of ER positive, hormonal therapy naïve primary breast carcinomas was immunohistochemically (IHC) stained for PSAT1. Staining was analyzed for association with patient's time to progression (TTP) and overall response on first-line tamoxifen for recurrent disease...

Background: Distant metastatic breast cancer (MBC), including metastases found at diagnosis (de novo) and those occurring later (recurrence), represents the most severe form of the disease, when resource utilization is most intensive. Yet, the number of women living with MBC in the United States is unknown. The objective of this article is to use population-based data to estimate the prevalence of MBC.Methods: We used a back-calculation method to estimate MBC prevalence from U.S. breast cancer mortality and survival from the Surveillance, Epidemiology and End Results (SEER) registries...

Although much research has examined the experience of breast cancer, the distinctive perspectives and lives of young women have been relatively neglected. Women diagnosed with breast cancer under the age of 45, and who had completed their initial treatment, were interviewed, and social constructionist grounded theory methods were used to analyse the data. The end of initial treatment was accompanied by a sense of unease and uncertainty in relation to recurrence and survival, and also fertility and menopausal status...

Triple-negative breast cancer (TNBC) indicates a subset of breast carcinomas that does not express estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2). According to the literature, TNBCs are aggressive tumors, characterized by a high incidence of recurrence and a high risk of disease progression. Lactoferrin (LF) is a single-chain, iron-binding glycoprotein of ~700 amino acids, which is involved in a wide range of biological activities, including iron-trafficking and carcinogenesis...

Nipple-sparing mastectomies (NSMs) are increasingly used in the surgical treatment of patients with breast cancer and for prevention of breast cancer. The present study was performed to review the outcomes of patients undergoing NSMs at a single large university setting. A retrospective chart review was performed on all patients undergoing NSMs from 2008-2014. Charts were reviewed for demographic data and patient characteristics. Tumor and breast size, cancer recurrence and complications were also evaluated...

In the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Breast Cancer, among adjuvant radiotherapy options for whole-breast irradiation after breast-conserving surgery, hypofractionation is preferred. For the use of accelerated partial-breast irradiation, the NCCN Guidelines have adopted the updated definition of "suitability" used by the American Society for Radiation Oncology. Regional nodal irradiation is indicated-either in the setting of breast-conserving surgery or after mastectomy-for women with ≥4 positive nodes and should be strongly considered for 1 to 3 positive lymph nodes and select patients with node-negative disease deemed at high risk for recurrence...

All patients with early breast cancer should be classified by subgroup through testing estrogen receptor, progesterone receptor, and HER2 status, with or without Ki-67 proliferation percentage. Genomic expression profiling aids clinical decision-making in most patients, because most are estrogen receptor-positive. The commercially available classifiers are prognostic for distant recurrence in node-negative and also node-positive patients. Patients at genomically low risk have excellent 5-year outcomes with endocrine therapy alone...

The nuclear receptor (NR) superfamily contains hormone-inducible transcription factors that regulate many physiological and pathological processes through regulating gene expression. NR4A1 is an NR family member that still does not have an identified endogenous ligand, and its role in cancer is also currently unclear and controversial. In this study, we aimed to define the expression profiles and specific role of NR4A1 in the highly malignant triple-negative breast cancer (TNBC), which still lacks available targeted therapies...

AIMS: Breast myxoid fibroadenomas (MFAs) are characterized by a distinctive hypocellular myxoid stroma, and occur sporadically or in the context of Carney Complex, an inheritable condition caused by PRKAR1A inactivating germline mutations. Conventional fibroadenomas (FAs) are underpinned by recurrent MED12 mutations in the stromal components of the lesions. We sought to investigate the genomic landscape of MFAs and compare it to that of conventional FAs. METHODS AND RESULTS: Eleven MFAs from patients without clinical and/or genetic evidence of Carney Complex were retrieved...

Several prospective randomized clinical trials conducted internationally have proven the safety and survival equivalence of breast-conserving surgery compared with mastectomy. Adjuvant radiation is routinely recommended following lumpectomy surgery to minimize the risk of local recurrence. Comprehensive breast imaging (including bilateral mammography with diagnostic views and ultrasound evaluation), in addition to clinical examination, is essential to rule out potential contralateral pathology and to optimally characterize the extent of disease...

Preclinical and early clinical trials indicate that up to 50% of triple-negative breast cancers (TNBC) express androgen receptor (AR) and are potentially responsive to anti-androgens. However, the function of AR in TNBC and the mechanisms by which AR-targeted therapy reduces tumor burden are largely unknown. We hypothesized that AR maintains a cancer stem cell (CSC)-like tumor initiating population and serves as an anti-apoptotic factor, facilitating anchorage independence and metastasis. AR levels increased in TNBC cells grown in forced suspension culture compared to those in attached conditions, and cells that expressed AR resisted detachment-induced apoptosis...

OBJECTIVE: Metastatic brain tumors are the most common brain tumors in adults. Patients with metastatic brain tumors have poor prognoses with median survival of 6-12 months. Seizures are a major presenting symptom and cause of morbidity and mortality. Risk factors for the onset of preoperative seizures and postoperative seizure control are examined. METHODS: Adult patients who underwent resection of one or more brain metastases at a single institution between 1998 and 2011 were retrospectively reviewed...

OBJECTIVE: Sleep can affect quality of life (QoL) during cancer survivorship, and symptoms related to poor sleep can be exacerbated. We examined the prevalence, severity, and nature of subjective sleep complaints in women surviving stage I-III breast cancer who were 1-10 years posttreatment. We also examined the demographic, medical, physical, and psychosocial correlates of poor sleep in these women in order to identify the subgroups that may be most in need of intervention. METHOD: A total of 200 patients at a comprehensive cancer center who were 1-10 years posttreatment for primary stage I-III breast cancer with no evidence of disease at the time of enrollment completed a battery of questionnaires on demographics, sleep, physical symptoms, mood, cancer-specific fears, and QoL...

Poly (ADP-ribose) polymerase (PARP) inhibitors have attracted much attention as one of the major molecular-targeted therapeutics for inhibiting DNA damage response. The PARP inhibitor, olaparib, has been clinically applied for treating certain recurrent ovarian cancer patients with BRCA1/2 mutations in Europe and the United States. It was also designated on 24 March 2017 as an orphan drug in Japan for similar clinical indications. In this review, we discuss (i) the prevalence of BRCA1/2 mutations in ovarian cancer, (ii) clinical trials of PARP inhibitors in ovarian cancer, (iii) genetic counseling for hereditary breast and ovarian cancer patients, and (iv) non-BRCA genes that may be associated with homologous recombination deficiency...

BACKGROUND: Breast reconstruction (BR) is an option for women who are treated with mastectomy; however, there has been concern regarding the oncologic safety of BR. In this study, we evaluated recurrences and mortality in women treated with mastectomy and compared outcomes in those treated with mastectomy alone to those with mastectomy plus transverse rectus adbominis (TRAM) flap BR. METHODS: The prospective cohort study included women treated with mastectomy at Women's College Hospital from 1987 to 1997...

We conducted a retrospective study to assess the follow-up of patients with localized breast cancer and the first indicators of advanced breast cancer recurrence. All patients with advanced breast cancer recurrence treated between January 2010 and June 2016 in our institution were registered. Among these patients, 303 patients initially treated for early breast cancer with curative intent were identified. After initial curative treatment, follow-up involved the oncologist, the general practitioner and the gynecologist in 68...
