The WW domain is composed of 38 to 40 semi-conserved amino acids shared with structural, regulatory, and signaling proteins. WW domain-binding protein 2 (WBP2), as a binding partner of WW domain protein, interacts with several WW-domain-containing proteins, such as Yes kinase-associated protein (Yap), paired box gene 8 (Pax8), WW-domain-containing transcription regulator protein 1 (TAZ), and WW-domain-containing oxidoreductase (WWOX) through its PPxY motifs within C-terminal region, and further triggers the downstream signaling pathway in vitro and in vivo...

Intraoperative partial breast radiotherapy is an alternative or an adjunct to fractionated whole breast irradiation for the administration of adjuvant radiotherapy in breast cancer following breast conserving surgery. Establishing intraoperative radiotherapy as a therapeutic modality requires a multidisciplinary approach to patient selection, workup, surgery, radiation protocols, chemotherapy, and patient follow up. In this article, we review the published evidence for best clinical practice, as a guide to the introduction of intraoperative radiotherapy for breast cancer treatment...

Current dietary guidelines for breast cancer patients (BCPs) fail to address adequate dietary intakes of macro- and micronutrients that may improve patients' nutritional status. This review includes information from the PubMed and Biomed Central databases over the last 15 y concerning dietary guidelines for BCPs and the potential impact of a personalized, nutrient-specific diet on patients' nutritional status during and after antineoplastic treatment. Results indicated that BCPs should receive a nutritional assessment immediately after diagnosis...

PURPOSE: Hyperthermia (40-44°C) effectively sensitizes tumors to radiotherapy by locally altering tumor biology. One of the effects of heat at the cellular level is inhibition of DNA repair by homologous recombination via degradation of the BRCA2-protein. This suggests that hyperthermia can expand the group of patients that benefit from PARP-inhibitors, a drug exploiting homologous recombination deficiency. Here, we explore whether the molecular mechanisms that cause heat-mediated degradation of BRCA2 are conserved in cell lines from various origins and, most importantly, whether, BRCA2 protein levels can be attenuated by heat in freshly biopted human tumors...

BACKGROUND/PURPOSE: The 21-gene recurrence score (RS) assay evaluates the likelihood of distant recurrence and benefit of chemotherapy in lymph node-negative, estrogen receptor (ER)-positive, HER2-negative breast cancer patients. The RS categories are associated with the risk of locoregional recurrence (LRR) in some, but not all studies. METHODS: We reviewed the institutional database to identify consecutive female patients with node-negative, ER+/HER2- breast carcinoma tested for the 21-gene RS assay and treated at our center from 2008 to 2013...

Dermatofibrosarcoma protuberans (DFSP) is a rare malignant tumor of subcutaneous tissue characterized by slow infiltrative growth. The tumor occurs in patients of all ages, with the highest frequency occurring between the second and the fifth decades of age. Genetically, DFSP is characterized by a reciprocal translocation t(17;22)(q22;q13), or more often, as a supernumerary ring chromosome involving chromosomes 17 and 22. Standard treatment of a localized tumor is surgical excision with wide margins. In the present study, a case report of a 43-year-old woman with a growing tumor in the left breast is discussed...

Many of the women newly diagnosed with breast cancer not have access to all the information they need to make the surgical and treatment choices that are most appropriate for them. Research clearly shows that lumpectomy and other breast-conserving surgeries are just as safe as mastectomy for most women with early stage disease, and yet approximately half will undergo the more disfiguring procedures, but many healthy women who have strong family histories of breast cancer consider prophylactic mastectomies, and their decisions are also based on very limited information, because there are few studies showing the effectiveness of that procedure...

Many of those who work in oncology or deal with cancer patients know of Prof. Umberto Veronesi and none of them could deny the importance of his battle against cancer. He devoted his life to improving cancer treatment and quality of life for patients. He was a physician, and a politician, but above all he was a researcher. He embodied the true spirit of research, i.e., to believe in something and investigate every aspect of it until all the questions about it have been satisfactorily answered. He never gave up when faced with challenges, and he never stopped being curious...

The goal of regional treatments in breast cancer should be to eradicate any disease within lymph nodes, avoid regional recurrences, minimize the risk of distant metastases, and improve survival. In addition, regional treatments should focus on reducing potential morbidities and optimizing the long-term quality of life of breast cancer survivors. While data from recent surgical and radiation trials have helped clarify many issues regarding regional treatment, there still remains controversy as to the optimal approach for patients with "intermediate risk" disease...

BACKGROUND: The incidence of ipsilateral breast tumor recurrence (IBTR) seems to be higher in BRCA-positive than sporadic breast cancer. We compared the oncologic outcomes of BRCA-positive breast cancer patients managed with breast-conserving surgery, simple mastectomy or mastectomy followed by immediate reconstruction. MATERIALS/METHODS: Thirty four BRCA-positive breast cancers were grouped according to surgical treatment: breast-conserving surgery (n = 17), simple mastectomy (n = 9), and mastectomy followed by immediate reconstruction (n = 8)...

Radiotherapy is able to improve locoregional control in breast cancer patients both after breast conserving surgery or mastectomy, with positive impact in high-risk patients for long-term survival. Recent advances in the precision of radiotherapy were based on the choice of the appropriate fractionation and technique. But the concept of adaptive radiotherapy is not only technical, and includes the biologic characterisation of the breast tumor. The knowledge that different subtypes of breast cancer can have distinct locoregional patterns of recurrence is consisted in the literature data...

Intraoperative assessment of sentinel lymph nodes (SLNs) has the advantage of allowing breast cancer patients with tumor-positive SLNs to avoid a second surgery by immediately proceeding to axillary lymph node dissection (ALND). However, there are several reasons why the use of intraoperative assessment should be questioned. Whereas ALND was traditionally advised for all breast cancer patients with tumor-positive lymph nodes for axillary staging and locoregional control, more recent studies have demonstrated safety of omitting ALND in a substantial number of patients...

For post-menopausal women with clinical stage II/III estrogen receptor positive (ER+) breast cancer neoadjuvant endocrine therapy (NET) is an under-utilized and low-toxicity alternative to chemotherapy for increasing breast conservation rates. Individual responses to endocrine therapy can also be used to tailor systemic treatment. The Preoperative Endocrine Prognostic Index (PEPI) was developed to identify patients at low risk of relapse after NET so that adjuvant chemotherapy can safely be avoided. In a recent validation study, patients with pathological stage 1 or 2A breast cancers with a Ki67 value of 2...

The relationship between age and breast cancer subtype is complex: both impact risk of locoregional recurrence (LRR) and survival. Young patients frequently present with aggressive tumors but the increased risk imparted by young age appears to differ among breast cancer subtypes. Dramatic improvements in local control among young women with breast cancer of all tumor subtypes have been observed, likely attributable to improved local therapy strategies, improvements in adjuvant therapies and implementation of subtype-specific targeted therapies...

The number of patients with ductal carcinoma in situ (DCIS) increases with more widely used screening mammography programs. DCIS accounts for approximately 20% of all new breast cancer diagnoses in these programs and the natural course of this heterogeneous group of pre-invasive lesions is not fully known. Better definition of subgroups benefitting from radiotherapy and knowledge on the natural course of DCIS are important issues for the future management of DCIS. Four large randomized trials have studied the effects of postoperative radiotherapy after breast conserving surgery in patients with wider spectrum of DCIS and all of them have shown radiotherapy to halve the risk of ipsilateral events, however, without any significant effect on breast cancer mortality...
