Research outputs 2014 to 2021

A loss of balance between G protein activation and deactivation has been implicated in the initiation of melanomas, and non-canonical Wnt signaling via the Wnt5A/Frizzled (FZD) pathway has been shown to be critical for the switch to an invasive phenotype. Daple [CCDC88C], a cytosolic guanine nucleotide exchange modulator (GEM) which enhances non-canonical Wnt5A/FZD signaling via activation of trimeric G protein, Gαi, has been shown to serve opposing roles-as an inducer of EMT and invasiveness and a potent tumor suppressor-via two isoforms, V1 (full-length) and V2 (short spliced isoform), respectively. Here we report that the relative abundance of these isoforms in …

BACKGROUND: Skeletal metastases present a major challenge for clinicians, representing an advanced and typically incurable stage of cancer. Bone is also the most common location for metastatic breast carcinoma, with skeletal lesions identified in over 80% of patients with advanced breast cancer. Preclinical models have demonstrated the ability of mechanical stimulation to suppress tumour formation and promote skeletal preservation at bone sites with osteolytic lesions, generating modulatory interference of tumour-driven bone remodelling. Preclinical studies have also demonstrated anti-cancer effects through exercise by minimising tumour hypoxia, normalising tumour vasculature and increasing tumoural blood perfusion. This study proposes to explore the promising …

INTRODUCTION: Preliminary evidence supports the beneficial role of physical activity on prostate cancer outcomes. This phase III randomised controlled trial (RCT) is designed to determine if supervised high-intensity aerobic and resistance exercise increases overall survival (OS) in patients with metastatic castrate-resistant prostate cancer (mCRPC).

METHODS AND ANALYSIS: Participants (n=866) must have histologically documented metastatic prostate cancer with evidence of progressive disease on androgen deprivation therapy (defined as mCRPC). Patients can be treatment-naïve for mCRPC or on first-line androgen receptor-targeted therapy for mCRPC (ie, abiraterone or enzalutamide) without evidence of progression at enrolment, and with no prior chemotherapy for mCRPC. Patients …

Feasibility And Preliminary Efficacy Of A 10-Week Resistance And Aerobic Exercise Intervention During Neoadjuvant Chemoradiation Treatment In Rectal Cancer Patients, Favil Singh, Daniel A. Galvão, Robert Newton, Nigel A. Spry, Michael K. Baker, Dennis Taaffe

Research outputs 2014 to 2021

Background:

Neoadjuvant chemoradiation treatment (CRT) in rectal cancer patients is associated with a reduction in physical capacity, lean mass and increased fatigue. As a countermeasure to these treatment-related adverse effects, we examined the feasibility and preliminary efficacy of a 10-week exercise program during CRT.

Methods:

Ten rectal cancer patients (7 men, aged 27-70 years, body mass index = 26.4 ± 3.8 kg/m2) receiving CRT undertook supervised resistance and aerobic exercise twice weekly. Assessments were undertaken pre- and post-intervention for upper and lower body muscle strength by 1-RM, muscle endurance, physical performance tests, body composition by dual X-ray absorptiometry, quality of …

Background: In Australia, cancer survival is significantly lower in non-metropolitan compared to metropolitan areas. Our objective was to evaluate the evidence on geographical variations in the clinical management and treatment of colorectal cancer (CRC).

Methods: A systematic review of published and gray literature was conducted. Five databases (CINAHL, PubMed, Embase, ProQuest, and Informit) were searched for articles published in English from 1990 to 2018. Studies were included if they assessed differences in clinical management according to geographical location; focused on CRC patients; and were conducted in Australia. Included studies were critically appraised using a modified Newcastle–Ottawa Scale. PRISMA systematic review …

A Diagnostic Autoantibody Signature For Primary Cutaneous Melanoma, Pauline Zaenker, Johnny Lo, Robert L. Pearce, Phillip Cantwell, Lester Cowell, Mark Lee, Christopher Quirk, Henry Law, Elin S. Gray, Mel R. Ziman Dr

Research outputs 2014 to 2021

Melanoma is an aggressive form of skin cancer that is curable by surgical excision in the majority of cases, if detected at an early stage. To improve early stage melanoma detection, the development of a highly sensitive diagnostic test is of utmost importance. Here we aimed to identify antibodies to a panel of tumour associated antigens that can differentiate primary melanoma patients and healthy individuals. A total of 245 sera from primary melanoma patients and healthy volunteers were screened against a high-throughput microarray platform containing 1627 functional proteins. Following rigorous statistical analysis, we identified a combination of 10 autoantibody biomarkers …

Circulating Tumour Dna: A Non-Invasive Biomarker For Melanoma, Ashleigh Cavell Mcevoy

Theses: Doctorates and Masters

Cutaneous melanoma accounts for 90% of all skin cancer deaths (Balch et al., 2010) and is responsible for 3.6% of deaths from cancer in Australia (Australian Institute of Health and Welfare, 2016). Whilst early detection and successful surgical removal of primary melanomas have improved survival rates (DeSantis et al., 2014), approximately 30% of these patients will have disease recurrence at some point in their lives (Soong et al., 1992; Soong et al., 1998). This is despite being considered disease free following treatment, which may have included surgical removal of the primary and/or its metastasis/es, radiation and/or systemic therapy. Whilst the …

Geographic Disparities In Previously Diagnosed Health Conditions In Colorectal Cancer Patients Are Largely Explained By Age And Area Level Disadvantage, Belinda C Goodwin, Sonja March, Michael J Ireland, Fiona Crawford-Williams, Shu-Kay Ng, Peter D Baade, Suzanne K. Chambers, Joanne F Aitken, Jeff Dunn

Research outputs 2014 to 2021

Background: Geographical disparity in colorectal cancer (CRC) survival rates may be partly due to aging populations and disadvantage in more remote locations; factors that also impact the incidence and outcomes of other chronic health conditions. The current study investigates whether geographic disparity exists amongst previously diagnosed health conditions in CRC patients above and beyond age and area-level disadvantage and whether this disparity is linked to geographic disparity in CRC survival.

Methods: Data regarding previously diagnosed health conditions were collected via computer-assisted telephone interviews with a cross-sectional sample of n = 1,966 Australian CRC patients between 2003 and 2004. Ten-year survival …
