BACKGROUND: The prognostic value of lymphocyte infiltration (LI) of colorectal carcinoma (CC) has been demonstrated by several groups. However, no validated test is currently available for clinical practice. We previously described an automated and reproducible method for testing LI and aimed to validate it for clinical use. PATIENTS AND METHODS: According to National Institutes of Health criteria, we designed a prospective validation of this biomarker in patients included in the PETACC8 phase III study...

BACKGROUND: Prostate cancer (PCa) is a leading reason of death in men and the most diagnosed malignancies in the western countries at the present time. After radical prostatectomy (RP), nearly 30% of men develop clinical recurrence with high serum prostate-specific antigen levels. An important challenge in PCa research is to identify effective predictors of tumor recurrence. The molecular alterations in microRNAs are associated with PCa initiation and progression. Several miRNA microarray studies have been conducted in recurrence PCa, but the results vary among different studies...

Invasive lobular carcinoma (ILC) is the second most common breast cancer subtype and accounts for 8-14% of all cases. Although the majority of human ILCs are characterized by the functional loss of E-cadherin (encoded by CDH1), inactivation of Cdh1 does not predispose mice to develop mammary tumors, implying that mutations in additional genes are required for ILC formation in mice. To identify these genes, we performed an insertional mutagenesis screen using the Sleeping Beauty transposon system in mice with mammary-specific inactivation of Cdh1...

OBJECTIVE: To determine rates of axillary dissection (ALND) and nodal recurrence in patients eligible for ACOSOG Z0011. BACKGROUND: Z0011 demonstrated that patients with cT1-2N0 breast cancers and 1 to 2 involved sentinel lymph nodes (SLNs) having breast-conserving therapy had no difference in locoregional recurrence or survival after SLN biopsy alone or ALND. The generalizability of the results and importance of nodal radiotherapy (RT) is unclear. METHODS: Patients eligible for Z0011 had SLN biopsy alone...

Chromodomain helicase DNA binding proteins (CHD) are characterized by N-terminal tandem chromodomains and a central ATP-dependent helicase domain. CHDs govern the cellular machinery's access to DNA, thereby playing critical roles in various cellular processes including transcription, proliferation, and DNA damage repair. Accumulating evidence demonstrates that mutation and dysregulation of CHDs are implicated in the pathogenesis of developmental disorders and cancer. However, we know little about genomic and transcriptomic alterations and the clinical significance of most CHDs in human cancer...

Growing evidence indicates that adiposity is associated with breast cancer risk and negatively affects breast cancer recurrence and survival, a paracrine role of mammary adipose tissue being very likely in this process. In contrast to other adipose depots, occurrence of a sub-inflammatory state of mammary adipose tissue defined by dying adipocytes surrounded by macrophages forming crown-like structures in overweight and obese subjects, remains only partially described. In a general population of breast cancer patients (107 patients) mostly undergoing breast-conserving surgery, we found a positive association between patient's body composition, breast adipocytes size, and presence of crown-like structures in mammary adipose tissue close to the tumor...

Cancer stem cells are responsible for tumor recurrence and metastasis. A new highly reproducible procedure for human breast cancer MCF-7 stem cells (BCSC) isolation and selection was developed by using a combination of hypoxia/hypoglycemia plus taxol and adriamycin for 24h. The BCSC enriched fraction (i) expressed (2-15 times) the typical stemness protein markers CD44+, ALDH1A3 and Oct 3/4; (ii) increased its clonogenicity index (20-times), invasiveness profile (>70%), migration capacity (100%) and ability to form mammospheres, compared to its non-metastatic MCF-7 counterpart...

PURPOSE: Invasive lobular carcinoma (ILC) of the breast has unique clinicopathologic characteristics, compared to invasive ductal carcinoma. The role of the 21-gene Recurrence Score (RS) has not been clearly defined for ILC. We sought to determine the prognostic value of RS and the impact of adjuvant chemotherapy on long-term survival in patients with ILC. METHODS: Utilizing the Surveillance, Epidemiology and End Results database from 2004 to 2013, we identified records of women aged 18-74 years, diagnosed with estrogen receptor (ER)-positive ILC (stage I to III) with RS available...

PURPOSE: Sentinel node biopsy (SNB) after neoadjuvant therapy (NAT) for breast cancer remains controversial. We conducted a retrospective study of patients who underwent SNB after NAT to evaluate the effectiveness of this procedure. METHODS: A consecutive 105 women with locally advanced breast cancer (cT1-4, cN0-3, M0) were treated with NAT between 2006 and 2015. The subjects were 80 of these patients who became or remained clinically node-negative after NAT, 53 of whom had axillary management determined by SNB (group A) and the other 27 underwent axillary lymph node dissection (ALND) without SNB (group B)...

INTRODUCTION: Management of complex cysts and benign intraductal/intracystic masses is controversial. The aim of this study was to determine if the complete removal of the complex cyst lesions with ultrasound-guided vacuum-assisted excision (US-VAE) is sufficient for their safe management when the histological diagnosis obtained at biopsy is benign. SUBJECTS AND METHODS: This is a single institution retrospective study performed on patients who underwent breast biopsy between April 2007 and September 2013...

INTRODUCTION: The conservative surgery is more and more indicated for breast cancer. However, we still fear local recurrence which is mostly due to residual tumors?. Several techniques have been used to minimize theses residual tumors; one of them is the systematic circumferential tumor cavity shaving (SCTCS). METHODS: We sampled 75 female patients who had conservative surgery with positive shaved margins in the anatomopathology examination and to whom a complementary treatment with mastectomy have been decided...

OBJECTIVE: Breast cancer survivors often take hormonal treatments to prevent the recurrence of breast cancer, particularly aromatase inhibitors that can worsen the symptoms of genitourinary syndrome of menopause (GSM) such as dyspareunia, dysuria, and urinary incontinence, all of which may adversely affect survivors' quality of life. Few breast cancer survivors experiencing GSM receive adequate assessment or treatment. METHODS: In this descriptive study, we reviewed medical records for documented GSM and any treatments administered or referrals for treatment in 800 female patients who visited the Breast Cancer Survivorship Clinic at a comprehensive cancer center between July 1, 2010 and June 30, 2011, either at least 5 years after completion of treatment for invasive breast cancer or at least 6 months after completion of treatment for ductal carcinoma in situ...

Most women use hormonal contraception for more than 30 years and for many, this may involve exposure in their older reproductive years when baseline breast cancer risk rises steeply. Overall, the risk of breast cancer diagnosis with exposure to hormonal contraception is very small and outweighed by its contraceptive benefits but despite this, there are still outstanding questions for all methods used in clinical practice due to paucity of available evidence, lack of which should not be taken to imply safety...

PURPOSE: Urine prostaglandin E2 (PGE2) levels have shown to be a risk factor of breast cancer, and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) is known to be beneficial in preventing breast cancer risk and/or recurrence with or without aromatase inhibitors. We hypothesized that the use of an aromatase inhibitor triggers the activation of the inflammatory pathway via release of PGE2. METHODS: A single oral 25 mg dose of an aromatase inhibitor (exemestane) was given to 14 healthy postmenopausal female volunteers...

Triple-negative breast cancer (TNBC) is a heterogeneous subtype with varying disease outcomes. Tumor-infiltrating lymphocytes (TILs) are frequent in TNBC and have been shown to correlate with outcome, suggesting an immunogenic component in this subtype. However, other factors intrinsic to the cancer cells may also influence outcome. To identify proteins and molecular pathways associated with recurrence in TNBC, 34 formalin-fixed paraffin-embedded (FFPE) primary TNBC tumors were investigated by global proteomic profiling using mass spectrometry...
