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 Jan 2018

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 …

The implementation of novel therapeutic interventions has improved the survival rates of melanoma patients with metastatic disease. Nonetheless, only 33% of treated cases exhibit long term responses. Circulating tumor cell (CTC) measurements are currently of clinical value in breast, prostate and colorectal cancers. However, the clinical utility of melanoma CTCs (MelCTCs) is still unclear due to challenges that appear intrinsic to MelCTCs (i.e. rarity, heterogeneity) and a lack of standardization in their isolation, across research laboratories. Here, we review the latest developments, pinpoint the challenges in MelCTC isolation and address their potential role in melanoma management.

Background: Circulating tumour DNA (ctDNA) may serve as a measure of tumour burden and a useful tool for non-invasive monitoring of cancer. However, ctDNA is not always detectable in patients at time of diagnosis of metastatic disease. Therefore, there is a need to understand the correlation between ctDNA levels and the patients' overall metabolic tumour burden (MTB). Methods: Thirty-two treatment naïve metastatic melanoma patients were included in the study. MTB and metabolic tumour volume (MTV) was measured by 18F-fluoro-D-glucose positron emission tomography/computed tomography (FDG PET/CT). Plasma ctDNA was quantified using droplet digital PCR (ddPCR). Results: CtDNA was detected in 23 …
