Early detection of breast cancer through screening can lower breast cancer mortality rates and reduce the burden of this disease in the population. In most western countries, mammography screening starting from age 50 is recommended. However, there is debate about whether breast cancer screening should be extended to younger women. This systematic review provides an overview of the evidence from RCT's on the benefits and harms of breast cancer screening with mammography in women aged 40 to 49 years. The quality of the evidence for each outcome was appraised using the GRADE approach...

As the sequencing cost continued to drop in the past decade, RNA sequencing (RNA-seq) has replaced microarray to become the standard high-throughput experimental tool to analyze transcriptomic profile. As more and more datasets are generated and accumulated in the public domain, meta-analysis to combine multiple transcriptomic studies to increase statistical power has received increasing popularity. In this article, we propose a Bayesian hierarchical model to jointly integrate microarray and RNA-seq studies...

PURPOSE: HER2-amplified breast cancer (BC) has a poor prognosis. The combination of trastuzumab with chemotherapy in the adjuvant setting decreases recurrence and improves overall survival in HER2-positive BC. However, the role of adjuvant treatment in patients with HER2-amplified small BC without lymph node involvement is still under debate. The purpose of this study was to investigate the safety of adjuvant paclitaxel and trastuzumab (APT) in this group of patients. METHODS: A total of 87 operated early BC patients without lymph node involvement (N0) were treated with APT for 12 weeks followed by trastuzumab alone for a total of 9 months...

INTRODUCTION: Evidence supporting the use of Sentinel node biopsy (SNB) for nodal staging of early oral squamous cell carcinomas (OSCC) appears to be very promising. Pre-operative lymphatic mapping using planar lymphoscinitigraphy (PL) with or without SPECT/CT in the SNB procedure is useful in sentinel node localization and for planning appropriate surgery. Recently, a large prospective multi-centric study evaluating SNB in cutaneous melanoma, breast and pelvic malignancies, demonstrated that adding SPECT to PL leads to surgical adjustments in a considerable number of patients...

The present study was designed to determine whether loss of heterozygosity (LOH) in the p arm of chromosome 9 in invasive ductal carcinoma of the breast is detected during the neoplastic progression of the disease. Using laser capture microdissection (LCM) epithelial cells were isolated from 14 invasive ductal carcinoma cases (IDC), ductal carcinomas in situ (DCIS), normal mammary lobules, skin and/or lymph nodes of paraffin embedded tissue sections. LOH analysis of chromosome 9p was performed utilizing the microsatellite markers D9S199, D9S157, D9S171, D9S265 and D9S270...

The replacement of sentinel lymph node biopsy (SNB) by ultrasound-guided fine-needle aspiration (US-guided FNA) cytology of axillary lymph nodes is controversial, despite the simplicity and reduced cost of the latter. In the present study, US-guided FNA was performed in 27 patients with early-stage breast cancer for comparison with SNB. Data were analyzed by calculation of sample proportions. Tumor subtypes included invasive ductal carcinoma (85%), invasive lobular carcinoma (7%), and tubular and metaplastic carcinoma (4%)...

INTRODUCTION: The most common malignant tumour among women is breast carcinoma. Early lesions of the breast including carcinoma are potentially curable if treated properly in the era of breast conservative therapy. For this purpose different diagnostic strategies are in practice. Intra operative Imprint Cytology (IC) and Frozen Section (FS) have a role in spite of the intense recognition of aspiration cytology in the following settings: inconclusive cytological/core biopsy findings; for evaluation of lumpectomy margins and intra operative nodal status...

Classical cadherins are the key molecules that control cell-cell adhesion. Notwithstanding this function, it is also clear that classical cadherins are more than just the "glue" that keeps the cells together. Cadherins are essential regulators of tissue homeostasis that govern multiple facets of cellular function and development, by transducing adhesive signals to a complex network of signaling effectors and transcriptional programs. In cancer, cadherins are often inactivated or functionally inhibited, resulting in disease development and/or progression...

The inflammatory response is known to have a significant role in certain autoimmune diseases and malignancies. We review current knowledge regarding the functions of activator protein 1 (AP-1) as an important modulator in several immune disorders and carcinomas. AP-1 is overexpressed in rheumatoid arthritis and in long-term allogeneic hematopoietic stem cell transplantation survivors; however, decreased expression of AP-1 has been observed in psoriasis, systematic lupus erythematosus and in patients who do not survive after hematopoietic stem cell transplantation...

Hereditary breast and ovarian carcinomas are frequently caused by germline mutations of the BRCA1 and BRCA2 genes (BRCA1/2 syndromes) and are often less associated with other hereditary syndromes such as Li-Fraumeni and Peutz-Jeghers. The BRCA1/2 proteins have a special role in DNA repair. Therefore, loss of function due to mutation causes an accumulation of mutations in other genes and subsequent tumorigenesis at an early age. BRCA1/2 mutations are irregularly distributed over the length of the genes without hot spots, although special mutations are known...

PURPOSE: Li-Fraumeni syndrome (LFS) is a rare genetic disease with strong predispositions to multiple early-onset neoplasms, mostly sarcomas, breast cancers, brain tumors and adrenocortical carcinomas (LFS core cancers). In most LFS families the germline mutations of TP53 tumor suppressor gene were found. Lung cancer does not belong to the core cancers of LFS, however its higher incidence is observed in families with TP53 mutations. Our aim was to search for TP53 mutations in female lung cancer patients whose clinico-demographic characteristics suggested a probable genetic predisposition to the disease...

Ductal carcinoma in situ (DCIS) has a good prognosis with the current treatment approach, with a 10-year breast cancer-specific survival rate of 97-98%. In ductal carcinoma in situ without micrometastasis, surgery and postoperative adjuvant therapy significantly improve local control, however it has been reported that the selection of the surgical procedure and adjuvant therapy does not influence breast cancer death. On the other hand, owing to widespread mammography screening, the frequency of early breast cancer detection has increased...

BACKGROUND: Heat shock protein (HSP90) is a molecular chaperone involved in maintaining protein homeostasis by modulating stability of de novo synthesized proteins. Neoplastic cells with high metabolic rate have higher expression of HSP90 and develop so called "chaperone addiction". Specific inhibition of HSP90 has been therefore discussed as a viable therapeutic strategy and several inhibitors of HSP90 have already entered clinical trials. Recently, a novel role for HSP90 was found on plasma membrane of cancer cells...
