Dynamic ctDNA Mutational Complexity in Patients with Melanoma Receiving Immunotherapy.

Background: Circulating tumour DNA (ctDNA) analysis promises to improve the clinical care of people with cancer, address health inequities and guide translational research. This observational cohort study used ctDNA to follow 29 patients with advanced-stage cutaneous melanoma through multiple cycles of immunotherapy.

Method: A melanoma-specific ctDNA next-generation sequencing (NGS) panel, droplet digital polymerase chain reaction (ddPCR) and mass spectrometry analysis were used to identify ctDNA mutations in longitudinal blood plasma samples from Aotearoa New Zealand (NZ) patients receiving immunotherapy for melanoma.

Complex Patterns of Genomic Heterogeneity Identified in 42 Tumor Samples and ctDNA of a Pulmonary Atypical Carcinoid Patient.

Unlabelled: Tumor evolution underlies many challenges facing precision oncology, and improving our understanding has the potential to improve clinical care. This study represents a rare opportunity to study tumor heterogeneity and evolution in a patient with an understudied cancer type. A patient with pulmonary atypical carcinoid, a neuroendocrine tumor, metastatic to 90 sites, requested and consented to donate tissues for research.

Chromosomal Aberrations Accumulate during Metastasis of Virus-Negative Merkel Cell Carcinoma.

Merkel cell carcinoma is a rare, aggressive skin tumor initiated by polyomavirus integration or UV light DNA damage. In New Zealand, there is a propensity toward the UV-driven form (31 of 107, 29% virus positive). Using archival formalin-fixed, paraffin-embedded tissues, we report targeted DNA sequencing covering 246 cancer genes on 71 tumor tissues and 38 nonmalignant tissues from 37 individuals, with 33 of 37 being negative for the virus.

The meaning of social support for persons with serious mental illness: A family member perspective.

Social support is essential to the health and well-being of persons with serious mental illness (SMI), and family members are a primary source of this support. Despite the primary role of family in the lives of persons with SMI, family is an understudied source of support. This study investigated the types of social support beneficial for persons with SMI from the perspective of family members.

Circulating tumor DNA is a sensitive marker for routine monitoring of treatment response in advanced colorectal cancer.

Accurate assessment of chemotherapy response provides the means to terminate ineffective treatment, trial alternative drug regimens or schedules and reduce dose to minimize toxicity. Here, we have compared circulating tumor DNA (ctDNA) with carcinoembryonic antigen (CEA) for the cycle by cycle assessment of chemotherapy response in 30 patients with metastatic colorectal cancer. CtDNA (quantified using individualized digital droplet PCR (ddPCR) assays) and CEA levels were determined immediately prior to each chemotherapy cycle over time periods ranging from 42-548 days (average of 10 time points/patient).

Specialized Cell-Free DNA Blood Collection Tubes Can Be Repurposed for Extracellular Vesicle Isolation: A Pilot Study.

Liquid biopsies offer a minimally invasive approach to patient disease diagnosis and monitoring. However, these are highly affected by preprocessing variables with many protocols designed for downstream analysis of a single molecular biomarker. Here we investigate whether specialized blood tubes could be repurposed for the analysis of an increasingly valuable biomarker, extracellular vesicles (EVs).

Accessing a New Dimension in TP53 Biology: Multiplex Long Amplicon Digital PCR to Specifically Detect and Quantitate Individual Transcripts.

, the most commonly-mutated gene in cancer, undergoes complex alternative splicing. Different transcripts play different biological roles, both in normal function and in the progression of diseases such as cancer. The study of alternative RNA splice forms and their use as clinical biomarkers has been hampered by limited specificity and quantitative accuracy of current methods.

A Predictor of Early Disease Recurrence in Patients With Breast Cancer Using a Cell-free RNA and Protein Liquid Biopsy.

Introduction: Circulating biomarkers have been increasingly used in the clinical management of breast cancer. The present study evaluated whether RNAs and a protein present in the plasma of patients with breast cancer might have utility as prognostic biomarkers complementary to existing clinical tests.

Patients And Methods: We performed microarray profiling of small noncoding RNAs in plasma samples from 30 patients with breast cancer and 10 control individuals.

Recurrent loss of heterozygosity correlates with clinical outcome in pancreatic neuroendocrine cancer.

Pancreatic neuroendocrine tumors (pNETs) are uncommon cancers arising from pancreatic islet cells. Here we report the analysis of gene mutation, copy number, and RNA expression of 57 sporadic well-differentiated pNETs. pNET genomes are dominated by aneuploidy, leading to concordant changes in RNA expression at the level of whole chromosomes and chromosome segments.

Assessing vocational outcome expectancy in individuals with serious mental illness: a factor-analytic approach.

: Self-determination theory (SDT) and self-efficacy theory (SET) can be used to conceptualize self-determined motivation to engage in mental health and vocational rehabilitation (VR) services and to predict recovery. To incorporate SDT and SET as a framework for vocational recovery, developing and validating SDT/SET measures in vocational rehabilitation is warranted. Outcome expectancy is an important SDT/SET variable affecting rehabilitation engagement and recovery.

Hunter and New England HealthPathways: a 4-year journey of integrated care.

Objective This paper describes the 4-year journey of Hunter and New England HealthPathways - a password-protected web-based portal designed to provide localised evidence-informed clinical and referral information to support general practice at the point of care. Methods A process evaluation was conducted in 2013, with a case study comparison performed in 2014 to assess impact of HealthPathways on patient referral and access to specialist care, followed by a review in 2016 of utilisation of the online portal to assess whether healthcare providers continued to access HealthPathways. Results Increased utilisation was correlated with an increase in the number of pathways published online.

A novel EGR-1 dependent mechanism for YB-1 modulation of paclitaxel response in a triple negative breast cancer cell line.

Chemotherapy with taxanes such as paclitaxel (PTX) is a key component of triple negative breast cancer (TNBC) treatment. PTX is used in combination with other drugs in both the adjuvant setting and in advanced breast cancer. Because a proportion of patients respond poorly to PTX or relapse after its use, a greater understanding of the mechanisms conferring resistance to PTX is required.

Psychometric validation of the Clubhouse climate questionnaire as an autonomy support measure for people with severe mental illness.

Background: Self-determination represents a paradigm shift from "shoulds" to "decisions and behaviors" as the best options for helping people with mental illness achieving recovery goals. Autonomy support plays an important role in self-determination.

Aims: The purpose of this study was to validate the Clubhouse climate questionnaire (CCQ) as an autonomy support measure.

Links between the oncoprotein YB-1 and small non-coding RNAs in breast cancer.

Background: The nucleic acid-binding protein YB-1, a member of the cold-shock domain protein family, has been implicated in the progression of breast cancer and is associated with poor patient survival. YB-1 has sequence similarity to LIN28, another cold-shock protein family member, which has a role in the regulation of small noncoding RNAs (sncRNAs) including microRNAs (miRNAs). Therefore, to investigate whether there is an association between YB-1 and sncRNAs in breast cancer, we investigated whether sncRNAs were bound by YB-1 in two breast cancer cell lines (luminal A-like and basal cell-like), and whether the abundance of sncRNAs and mRNAs changed in response to experimental reduction of YB-1 expression.
