Celiac plexus radiosurgery for pain management in advanced cancer: a multicentre, single-arm, phase 2 trial.

Background: Refractory upper abdominal pain or lower back pain (retroperitoneal pain syndrome) related to celiac plexus involvement characterises pancreatic and other upper gastrointestinal malignancies and is an unmet need. We hypothesised that ablative radiation delivered to the celiac plexus would decrease pain.

Methods: This multicentre, single-arm, phase 2 study was done at eight hospitals in five countries (Israel, Poland, Canada, the USA, and Portugal).

Understanding quality of life issues in patients with advanced melanoma: Phase 1 and 2 in the development of the EORTC advanced melanoma module.

Aims: We aimed to develop a European Organization for Research and Treatment of Cancer (EORTC) Quality of Life (QoL) module tailored for patients with advanced (resectable or unresectable stage III/IV) melanoma receiving immune checkpoint inhibitors or targeted therapy.

Methods: Following the EORTC QoL Group module development guidelines, we conducted phases 1 and 2 of the development process. In phase 1, we generated a list of health-related (HR)QoL issues through a systematic literature review and semi-structured interviews with healthcare professionals (HCPs) and patients with advanced melanoma.

Cancer pain patients do not successfully handle opioids.

Objective: To evaluate patterns of opioid handling as well as their associated -variables.

Design: A transversal study.

Setting: Institutional care.

Coeliac plexus radiosurgery for pain management in patients with advanced cancer : study protocol for a phase II clinical trial.

Introduction: Pancreatic cancer is characterised by severe mid-back and epigastric pain caused by tumour invasion of the coeliac nerve plexus. This pain is often poorly managed with standard treatments. This clinical trial investigates a novel approach in which high-dose radiation (radiosurgery) is targeted to the retroperitoneal coeliac plexus nerve bundle.

Single-Fraction Celiac Plexus Radiosurgery: A Preliminary Proof-of-Concept Phase 2 Clinical Trial.

Background: Refractory epigastric/midback pain is associated with locally advanced abdominal malignancies, especially pancreatic cancer. The pain is caused by tumor infiltration of the celiac plexus, a nerve network attached to the abdominal aorta. Contemporary palliative approaches are often inadequate.

Phase III study of the European Organisation for Research and Treatment of Cancer Quality of Life cancer survivorship core questionnaire.

Purpose: The purpose of this study is to develop a European Organisation for Research and Treatment of Cancer Quality of Life Group (EORTC QLG) questionnaire that captures the full range of physical, mental, and social health-related quality of life (HRQOL) issues relevant to disease-free cancer survivors. In this phase III study, we pretested the provisional core questionnaire (QLQ-SURV111) and aimed to identify essential and optional scales.

Methods: We pretested the QLQ-SURV111 in 492 cancer survivors from 17 countries with one of 11 cancer diagnoses.

Preliminary assessment of medical cannabis consumption by cancer survivors.

Objectives: To assess the motivation of cancer survivors to consume medical cannabis and to assess the patterns of use, perceived efficacy, as well as side and adverse effects.

Methods: Cross-sectional survey among 190 Israeli cancer survivors who were licensed to use medical cannabis in a single institution. In addition to demographic information, the questionnaire examined patterns of use (including dosage, type of cannabis and way of administration), motivation for medical cannabis consumption, perceived efficacy, adverse and side effects, motivation for ceasing cannabis consumption, and tobacco smoking.

Medical cannabis treatment for chronic pain: Outcomes and prediction of response.

Background: Although studied in a few randomized controlled trials, the efficacy of medical cannabis (MC) for chronic pain remains controversial. Using an alternative approach, this multicentre, questionnaire-based prospective cohort was aimed to assess the long-term effects of MC on chronic pain of various aetiologies and to identify predictors for MC treatment success.

Methods: Patients with chronic pain, licensed to use MC in Israel, reported weekly average pain intensity (primary outcome) and related symptoms before and at 1, 3, 6, 9 and 12 months following MC treatment initiation.

Gender effects on quality of life and symptom burden in patients with lung cancer: results from a prospective, cross-cultural, multi-center study.

Background: Lung cancer causes impairment of health-related quality of life (QoL), but little is known about gender aspects in QoL and symptom burden of lung cancer patients. The aim of this study was to investigate gender differences in QoL as assessed by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and the updated lung cancer module.

Methods: In a prospective, international, cross-cultural, multicenter study that was undertaken to update the lung cancer-specific module EORTC QLQ-LC13, patients filled in the core questionnaire EORTC QLQ-C30 and the updated lung cancer module.

Effect of the botanical compound LCS102 on innate immunity.

Innate immunity serves an important role in the healthy population, providing surveillance and protection against infections. Chemotherapy suppresses the body's immune system, including neutrophil and natural killer (NK) cell numbers and activity. This leads to an increased risk of infection which often requires the reduction or even discontinuation of the chemotherapeutic regimens.

Psychometric properties of the updated EORTC module for assessing quality of life in patients with lung cancer (QLQ-LC29): an international, observational field study.

Background: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) assesses quality of life (QOL) in patients with lung cancer and was the first EORTC module developed for use in international clinical trials. Since its publication in 1994, major treatment advances with possible effects on QOL have occurred. These changes called for an update of the module and its international psychometric validation.

Understanding the quality of life (QOL) issues in survivors of cancer: towards the development of an EORTC QOL cancer survivorship questionnaire.

Backround: The number of cancer survivors is growing steadily and increasingly, clinical trials are being designed to include long-term follow-up to assess not only survival, but also late effects and health-related quality of life (HRQOL). Therefore it is is essential to develop patient-reported outcome measures (PROMs) that capture the full range of issues relevant to disease-free cancer survivors. The objectives of this project are: 1) to develop a European Organisation for Research and Treatment of Cancer (EORTC) questionnaire that captures the full range of physical, mental and social HRQOL issues relevant to disease-free cancer survivors; and 2) to determine at which minimal time since completion of treatment the questionnaire should be used.

Filamentous Bacteriophage Viruses: Preparation, Magic-Angle Spinning Solid-State NMR Experiments, and Structure Determination.

Filamentous bacteriophages are elongated semi-flexible viruses that infect bacteria. They consist of a circular single-stranded DNA (ssDNA) wrapped by a capsid consisting of thousands of copies of a major coat protein subunit. Given the increasing number of discovered phages and the existence of only a handful of structures, the development of methods for phage structure determination is valuable for biophysics and structural virology.

An international study to revise the EORTC questionnaire for assessing quality of life in lung cancer patients.

Background: The European Organization for Research and Treatment of Cancer (EORTC) QLQ-LC13 was the first module to be used in conjunction with the core questionnaire, the QLQ-C30. Since the publication of the LC13 in 1994, major advances have occurred in the treatment of lung cancer. Given this, an update of the EORTC QLQ-LC13 was undertaken.

Structural Effects of Single Mutations in a Filamentous Viral Capsid Across Multiple Length Scales.

Filamentous bacteriophage (phage) are single-stranded DNA viruses that infect bacteria. Single-site mutants of fd phage have been studied by magic-angle spinning nuclear magnetic resonance and by small-angle X-ray scattering. Detailed analysis has been performed that provides insight into structural variations on three length scales.

Magic-angle spinning NMR of intact bacteriophages: insights into the capsid, DNA and their interface.

Bacteriophages are viruses that infect bacteria. They are complex macromolecular assemblies, which are composed of multiple protein subunits that protect genomic material and deliver it to specific hosts. Various biophysical techniques have been used to characterize their structure in order to unravel phage morphogenesis.

[Use of herbal medicine for cancer treatment-related toxicities].

Cancer treatment-related toxicities often require dose reductions and delays. Herbal medicine use is prevalent among cancer patients. Though evidence is lacking regarding benefits in treatment outcomes and immunity, a large body of evidence supports the use of herbals for reducing treatment-induced toxicities.

The NMR-Rosetta capsid model of M13 bacteriophage reveals a quadrupled hydrophobic packing epitope.

Filamentous phage are elongated semiflexible ssDNA viruses that infect bacteria. The M13 phage, belonging to the family inoviridae, has a length of ∼1 μm and a diameter of ∼7 nm. Here we present a structural model for the capsid of intact M13 bacteriophage using Rosetta model building guided by structure restraints obtained from magic-angle spinning solid-state NMR experimental data.

Complete chemical shift assignment of the ssDNA in the filamentous bacteriophage fd reports on its conformation and on its interface with the capsid shell.

The fd bacteriophage is a filamentous virus consisting of a circular single-stranded DNA (ssDNA) wrapped by thousands of copies of a major coat protein subunit (the capsid). The coat protein subunits are mostly α-helical and curved, and are arranged in the capsid in consecutive pentamers related by a translation along the main viral axis and a rotation of ~36° (C5S2 symmetry). The DNA is right-handed and helical, but information on its structure and on its interface with the capsid is incomplete.

Preliminary report of the relationship between experience of death of a relative, illness perception, and psychological outcome among BRCA carriers.

With recent advances in mapping the genetic mutations involved in breast cancer and the availability of genetic testing, it has become necessary to explore the psychological consequences of women who have tested positive for the gene mutations involved in breast cancer (BReast CAncer gene one and two, BRCA1/2). Findings regarding psychological consequences of positive results in genetic testing for breast cancer are ambiguous and insufficient. The aim of the current study was to explore the relationship between experience of the death of a relative due to breast cancer, perception of the illness, distress, and well-being among BRCA1/2 mutation women carriers.

Association between metabolic syndrome, diabetes mellitus and prostate cancer risk.

Background: The worldwide incidence of diabetes mellitus is rapidly increasing. There is recent interest in the influence of glucose metabolism on oncogenesis. We investigated the role of diabetes mellitus and the metabolic syndrome (MS) on prostate cancer development.
