BACKGROUND: Surgery is the cornerstone of treatment for many solid tumours. A wide variety of imaging modalities are available before surgery for staging, although surgeons still rely primarily on visual and haptic cues in the operating environment. Image and molecular guidance might improve the adequacy of resection through enhanced tumour definition and detection of aberrant deposits. Intraoperative modalities available for image- and molecular-guided cancer surgery are reviewed here...

Androgen-deprivation therapy (ADT) remains the cornerstone of management for patients with metastatic prostate cancer. Although the toxicities of ADT are well established, there is increasing controversy surrounding the association between cognitive dysfunction and the receipt of ADT, with some evidence suggesting an increased risk of dementia. The authors conducted a literature search to identify pertinent clinical studies in this field. This general review outlines the key findings and discusses the relative strengths and weaknesses when drawing conclusions about the risk of cognitive dysfunction or dementia with ADT use...

BACKGROUND: To screen tumors with microsatellite instability (MSI) arising due to DNA mismatch repair deficiency (dMMR), a panel of five quasi-monomorphic mononucleotide-repeat markers amplified in a multiplex PCR (Pentaplex) are commonly used. In spite of its several strengths, the pentaplex assay is not robust at detecting the loss of MSH6-deficiency (dMSH6). In order to overcome this challenge, we designed this study to develop and optimize a panel of four quasi-monomorphic mononucleotide-repeat markers (Tetraplex) for identifying solid tumors with dMMR, especially dMSH6...

Improper signaling of the nuclear factor-κB (NF-κB) pathway plays a critical role in many inflammatory disease states including cancer, stroke, and viral infections. Although the signaling pathways are known, how these molecular mechanisms respond to changes in the intracellular microenvironment such as pH, ionic strength, and temperature, remains elusive. Molecular dynamics simulations were employed to differentiate the structural dynamics of the NF-kB Inducing Kinase (NIK), a protein kinase responsible for invoking the non-canonical NF-κB pathway, in its native and mutant form, and in the absence and presence of salt concentration in efforts to probe whether changes in the ionic environment stabilize or destabilize the NIK dimer...

Marc A M Mureau
Treatment of breast cancer is complex and multidisciplinary by nature, with protocols that are updated continuously. During preoperative multidisciplinary team meetings, regularly there is discussion between team members regarding optimal timing and type of breast reconstruction, due to conflicting interests of oncological and reconstructive treatments. Therefore, a multidisciplinary, evidence-based guideline for breast reconstruction in women undergoing breast conserving therapy or mastectomy for breast cancer, or following prophylactic mastectomy was developed by a multidisciplinary working group...

Patients with esophageal cancer are at high risk of developing malnutrition during neoadjuvant chemoradiation therapy (CRT), which in turn is associated with postoperative morbidity. The aim of the study is to explore whether parameters of a complete pre-treatment nutritional status may predict deterioration of nutritional status during CRT in patients with esophageal cancer. In this prospective cohort study, 101 patients with esophageal cancer treated with CRT were included. Data of patient characteristics, tumor classification, performance score, %weight change, body mass index, fat (free) mass index, phase angle, handgrip strength, energy- and protein intake, and use of (additional) dietary supplements were collected...

Collective cell migration is a fundamental process during embryogenesis and its initial occurrence, called epiboly, is an excellent in vivo model to study the physical processes involved in collective cell movements that are key to understanding organ formation, cancer invasion, and wound healing. In zebrafish, epiboly starts with a cluster of cells at one pole of the spherical embryo. These cells are actively spreading in a continuous movement toward its other pole until they fully cover the yolk. Inspired by the physics of wetting, we determine the contact angle between the cells and the yolk during epiboly...

The RNASEL -1385G/A (rs486907) variant has been reported to be associated with increased risk of prostate cancer. However, these associations are not consistent among studies. To address this issue, we performed a meta-analysis to evaluate the association between RNASEL -1385G/A polymorphism and prostate cancer risk. The PubMed, Embase, and Web of Science databases were searched for relevant papers published in the past 20 years from 1997 to 2017. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of associations...

Coregulators cooperate with nuclear receptors, such as the glucocorticoid receptor (GR), to enhance or repress transcription. These regulatory proteins are implicated in cancer, yet, their role in lymphoid malignancies, including multiple myeloma (MM) and acute lymphoblastic leukemia (ALL), is largely unknown. Here, we report the use and extension of the microarray assay for real-time nuclear receptor coregulator interactions (MARCoNI) technology to detect coregulator associations with endogenous GR in cell lysates...
