Background

The validity of circulating tumour DNA (ctDNA) as an indicator of disease progression compared to medical imaging in patients with metastatic melanoma requires detailed evaluation.

Methods

Here, we carried out a retrospective ctDNA analysis of 108 plasma samples collected at the time of disease progression. We also analysed a validation cohort of 66 metastatic melanoma patients monitored prospectively after response to systemic therapy.

Results

ctDNA was detected in 62% of patients at the time of disease progression. For 67 patients that responded to treatment, the mean ctDNA level at progressive disease was significantly higher than at the time of …

Musculoskeletal Responses To Exercise Plus Nutrition In Men With Prostate Cancer On Androgen Deprivation: A 12-Month Rct, Jack Dalla Via, Patrick J. Owen, Robin M. Daly, Niamh L. Mundell, Patricia M. Livingston, Timo Rantalainen, Stephen J. Foulkes, Jeremy L. Millar, Declan G. Murphy, Steve F. Fraser

Purpose:

Androgen deprivation therapy (ADT) for prostate cancer has multiple adverse effects on musculoskeletal health. This 12-month randomized controlled trial aimed to assess the effects of multicomponent exercise training combined with whey protein, calcium and vitamin D supplementation on bone mineral density (BMD), structure and strength, body composition, muscle strength, and physical function in ADT-treated men.

Methods:

Seventy ADT-treated men were randomized to exercise plus supplementation (Ex + Suppl; n = 34) or usual care (control; n = 36). Ex + Suppl involved thrice weekly progressive resistance training plus weight-bearing impact exercise with daily multinutrient supplementation. Primary outcomes were DXA …

Adipogenesis associated Mth938 domain containing (AAMDC) represents an uncharacterized oncogene amplified in aggressive estrogen receptor-positive breast cancers. We uncover that AAMDC regulates the expression of several metabolic enzymes involved in the one-carbon folate and methionine cycles, and lipid metabolism. We show that AAMDC controls PI3K-AKT-mTOR signaling, regulating the translation of ATF4 and MYC and modulating the transcriptional activity of AAMDC-dependent promoters. High AAMDC expression is associated with sensitization to dactolisib and everolimus, and these PI3K-mTOR inhibitors exhibit synergistic interactions with anti-estrogens in IntClust2 models. Ectopic AAMDC expression is sufficient to activate AKT signaling, resulting in estrogen-independent tumor growth. Thus, AAMDC-overexpressing …

An Integrated Multicomponent Care Model For Men Affected By Prostate Cancer: A Feasibility Study Of Truenth Australia, Patsy Yates, Rob Carter, Robyn Cockerell, Donna Cowan, Cyril Dixon, Anne Magnus, Robert U.

Objective: To evaluate the feasibility of implementing an integrated multicomponent survivorship care model for men affected by prostate cancer. Methods: Using a single arm prospective cohort study design, men with prostate cancer were recruited from two regional public hospitals in Australia for a 6-months program that provided information and decision support, exercise and nutrition management, specialised clinical support, and practical support through localised and central care coordination. Carers of the men were also invited to the program. Data were collected from multiple sources to evaluate: (1) recruitment capability and participant characteristics; (2) appropriateness and feasibility of delivering the specific intervention …

Epidemiological Overview Of Multidimensional Chromosomal And Genome Toxicity Of Cannabis Exposure In Congenital Anomalies And Cancer Development, Albert Stuart Reece, Gary K. Hulse

Research outputs 2014 to 2021

Cannabis and cannabinoids are implicated in multiple genotoxic, epigenotoxic and chromosomal-toxic mechanisms and interact with several morphogenic pathways, likely underpinning previous reports of links between cannabis and congenital anomalies and heritable tumours. However the effects of cannabinoid genotoxicity have not been assessed on whole populations and formal consideration of effects as a broadly acting genotoxin remain unexplored. Our study addressed these knowledge gaps in USA datasets. Cancer data from CDC, drug exposure data from National Survey of Drug Use and Health 2003–2017 and congenital anomaly data from National Birth Defects Prevention Network were used. We show that cannabis, THC cannabigerol …

Evaluation Of A Remote Symptom Assessment And Management (Sam) System For People Receiving Adjuvant Chemotherapy For Breast Or Colorectal Cancer: Mixed Methods Study, Lisa Whitehead, Laura Emery, Deborah Kirk, Diane Twigg, Deborah Brown, Joanna Dewar

Research outputs 2014 to 2021

©Lisa Whitehead, Laura Emery, Deborah Kirk, Diane Twigg, Deborah Brown, Joanna Dewar. Background: The Symptom Assessment and Management (SAM) program is a structured, online, nurse-supported intervention to support symptom self-management in people receiving adjuvant chemotherapy post surgery for breast or colorectal cancer. Objective: The objective of this study was to describe the development, implementation strategy, and evaluation of the SAM system. Methods: The development of the SAM program involved 3 phases. In phase 1, the web app was developed through consultation with consumers and clinicians and of the literature to ensure that the system was evidence-based and reflected the realities …
