USP7 is a deubiquitinase implicated in destabilizing the tumor suppressor p53 and for this reason it has gained increasing attention as a potential oncology target for small molecule inhibitors. Herein we describe the biophysical, biochemical and computational approaches that led to the identification of 4-(2-aminopyridin-3-yl)-phenol compounds described by Kategaya et al.1 as specific inhibitors of USP7. Fragment based lead discovery (FBLD) by NMR combined with virtual screening and re-mining of biochemical high-throughput screening (HTS) hits led to the discovery of a series of ligands that bind in the "palm" region of the catalytic domain of USP7 and inhibit its catalytic activity...

Shivani Ahlawat, Laura M Fayad
Diffusion-weighted imaging (DWI) is a fast, non-contrast technique that is readily available and easy to integrate into an existing imaging protocol. DWI with apparent diffusion coefficient (ADC) mapping offers a quantitative metric for soft tissue evaluation and provides information regarding the cellularity of a region of interest. There are several available methods of performing DWI, and artifacts and pitfalls must be considered when interpreting DWI studies. This review article will review the various techniques of DWI acquisition and utility of qualitative as well as quantitative methods of image interpretation, with emphasis on optimal methods for ADC measurement...

The introduction into routine hematology-oncology clinical practice of molecular genetic testing assays based on next-generation sequencing platforms is prompting reassessment of the importance of molecular assay results in comparison to existing disease-specific risk stratification tools based on clinical assessment and light microscopy. For patients with myelodysplastic syndromes (MDS), the most commonly used tools for prognostication currently include the International Prognostic Scoring System (IPSS) and the Revised IPSS (IPSS-R), which are based on marrow blast proportion, number and degree of cytopenias, and the metaphase karyotype...

Micro-RNAs (miRNAs) are potent regulators of gene expression and cellular phenotype. Each miRNA has the potential to target hundreds of transcripts within the cell thus controlling fundamental cellular processes such as survival and proliferation. Here, we exploit this important feature of miRNA networks to discover vulnerabilities in cancer phenotype, and map miRNA-target relationships across different cancer types. More specifically, we report the results of a functional genomics screen of 1280 miRNA mimics and inhibitors in eight cancer cell lines, and its presentation in a sophisticated interactive data portal...

BACKGROUND AND AIMS: The phase angle (PA), derived from bioelectrical impedance analysis (BIA), has been interpreted as a cell membrane integrity indicator, while handgrip strength (HGS) has been used as a prognostic indicator in certain clinical situations, such as in cardiac, oncologic patients with renal disease, hemodialysis patients, HIV-positive patients, and liver disease patients. In addition to prognostic scores, body changes due to surgical procedures indicate the importance of measuring muscle function and cell integrity...

In the era of modern communication, the physician and patient relationship has evolved to include an entirely new dimension-social media. This new dimension offers several opportunities for patient education, research and its dissemination, and professional development for health care providers; it can also serve as a platform for addressing important public health issues. However, these advantages come with challenges such as threats to patient and professional privacy. In this article, we dissect the benefits and drawbacks of this social evolution on the practicing hematologist-oncologist...

The use of social media, and in particular, Twitter, for professional use among healthcare providers is rapidly increasing across the world. One medical subspecialty that is leading the integration of this new platform for communication into daily practice and for information dissemination to the general public is the field of hematology/oncology. A growing amount of research in this area demonstrates that there is increasing interest among physicians to learn not only how to use social media for consumption of educational material, but also how to generate and contribute original content in one's interest/expert areas...

Social media utilizes specific media platforms to allow increased interactivity between participants. These platforms serve diverse groups and purposes including participation from patients, family caregivers, research scientists, physicians, and pharmaceutical companies. Utilization of these information outlets has increased with integration at conferences and between conferences with the use of hashtags and "chats". In the realm of the "e-Patient" it is key to not underestimate your audience. Highly technical information is just as useful as a basic post...

Genetic testing for hereditary cancer syndromes is an integral component of oncology care. Various types of common errors that occur in the genetic testing process are presented in this article with actual clinical case examples and commentary. Genetic errors are expensive and may result in poor outcomes for the patient and his or her family. Oncology nurses need to be aware of potential sources of error and advocate for comprehensive genetic care.

We previously reported on a family with hereditary lung cancer, in which a germline mutation in the transmembrane domain (G660D) of avian erythroblastic leukemia viral oncogene homolog 2 (erb-b2 receptor tyrosine kinase 2) (ERBB2; human epidermal growth factor receptor 2 [HER2]) seemed to be responsible for the cancer predisposition. Although few data are available on treatment, anti-ERBB2 therapeutic agents may be effective for ERBB2-mutant cancers. The familial lung cancer patient in one of the authors' institutes developed bone metastasis with enlarging lung tumors and was treated with the ERBB2 inhibitor afatinib...

Multidisciplinary tumour board is an integral part of cancer treatment planning. Although no definite survival benefits have yet been shown by mostly observational studies, other benefits of multidisciplinary tumour board have been identified. Traditionally the multidisciplinary tumour board involves participation of treating clinicians-medical, radiation and surgical oncologists. They tend to focus on the cancer alone. There is an increasing awareness that the treatment goal for cancer in older adults is not primarily on prolonging survival, with functional preservation and quality of life being particularly important for this population...

Purpose The early integration of oncology and palliative care (EIPC) improves quality of life (QOL) and mood for patients with advanced cancer. However, the mechanisms by which EIPC benefits these outcomes remain unclear. We therefore examined whether EIPC improved patients' coping strategies and if changes in coping accounted for intervention effects on QOL and depressive symptoms. Patients and Methods For this secondary analysis of an EIPC trial, we examined data from 350 patients with newly diagnosed incurable lung or GI cancer...

The Middle East is a promising arena in which researchers can explore the interchange between cross-cultural traditional medicine and supportive cancer care, as provided within an integrative oncology setting. Integrative oncology research and clinical practice in this part of the world have been focusing, for the most part, on the use of herbal medicine and mind-body-spiritual modalities, both of which are deeply rooted in traditional medical care. A regional, multinational, and interdisciplinary collaboration is currently being undertaken as part of the academic activities of the Middle-East Research Group in Integrative Oncology (MERGIO)...

Significant strides have been made in the treatment of childhood cancer. Improvements in survival have led to increased attention toward supportive care indications; including the use of traditional and complementary medicine (T&CM). The use of T&CM among children and adolescents with cancer is well documented in both high-income countries (HICs) and low-middle income countries (LMICs). A higher incidence of the use of T&CM has been reported among children undergoing treatment in LMICs, which has elevated concerns related to drug interactions, adherence to therapy, and treatment-related toxicities...

Background: Integrative oncology, which is generally understood to refer to the use of a combination of complementary medicine therapies in conjunction with conventional cancer treatments, has been defined in different ways, but there is no widely accepted definition. We sought to develop and establish a consensus for a comprehensive definition of the field of integrative oncology. Methods: We used a mixed-methods approach that included a literature analysis and a consensus procedure, including an interdisciplinary expert panel and surveys, to develop a comprehensive and acceptable definition for the term "integrative oncology...
