Uveal melanoma is the most common primary ocular malignancy in adults, characterized by gene mutations in G protein subunit alpha q (GNAQ) and G protein subunit alpha 11 (GNA11). Although they are considered to be driver mutations, their role in MUM remains elusive. We investigated key somatic mutations of MUM and their impact on patients’ survival after development of systemic metastasis (Met-to-Death). Metastatic lesions from 87 MUM patients were analyzed by next generation sequencing (NGS). GNA11 (41/87) and GNAQ (39/87) mutations were most predominantly seen in MUM. Most GNA11 mutations were Q209L (36/41), whereas GNAQ mutations comprised Q209L (14/39) and …

The objective of this study was to use material from a randomized clinical trial to evaluate whether patients with preexisting immune infiltrates responded better to treatment with gemcitabine + docetaxel (GD) compared to docetaxel alone. Formalin fixed, paraffin-embedded breast cancer tissues from SBG0102 phase 3 trial patients randomly assigned to treatment with GD or docetaxel were used. Immunohistochemical staining for CD8, FOXP3, LAG3, PD-1, PD-L1 and CD163 was performed. Tumor infiltrating lymphocytes (TILs) and tumor associated macrophages were evaluated. Prespecified …


Mucin And Splice Variant Profiles Of Pancreatic Adenocarcinoma Predict Patient Survival And Subtyping, Christopher M. Thompson May 2021

Mucin And Splice Variant Profiles Of Pancreatic Adenocarcinoma Predict Patient Survival And Subtyping, Christopher M. Thompson

Theses & Dissertations

PDAC is a pancreatic epithelial malignancy and demonstrates aggressive progression and bleak patient prognosis. Despite decades of research, the evolution of novel diagnostics and intervention modalities for PDAC is stagnant. This dissertation explores the characteristic aberrant and elevated expression of mucins in PDAC. Beginning with the hypothesis that mucins are associated with disease aggressiveness, analysis of PDAC patient survival in TCGA revealed no associations between single mucin expression and patient survival. This led to the underlying issue of PDAC tumor cellularity since this disease demonstrates variability in the proportion of cancer cells within the tumor. Tumor purity assessed with the …

Prostate Cancer Survivorship Care: If Not Now, When?, Jeffrey Dunn, Peter Heathcote, Suzanne K. Chambers

Research outputs 2014 to 2021

Prostate cancer is the most common cancer diagnosed in Australian men, excluding non-melanoma skin cancer, and it is estimated that there are over 220 000 Australian men living with a diagnosis of prostate cancer [1]. Survival for men with prostate cancer is excellent in countries that have accessible screening and treatment services, and in Australia 5-year relative survival is over 95% [1]. High incidence, coupled with improving long-term survival, leads to a correspondingly high prevalence rate and high community disease burden. Many men with prostate cancer experience long-term decrements in their mental and physical quality of life, overall they have …

Background/aim: To investigate the utility of preoperative serum cancer antigen 125 (CA 125) levels in type 1 endometrial carcinoma (EC) as a marker for determining poor prognostic factors and survival. Material and methods: All patients with endometrial cancer, who had been treated between 2012 and 2020, were retrospectively reviewed, and finally, 256 patients with type 1 endometrium carcinoma were included in the study. The relationship between the clinicopathological characteristics, CA 125 level, and survival rates were analyzed. The cut-off value for the preoperative serum CA 125 level was defined as 16 IU/L. Results: The median serum CA 125 levels were …

Background/aim: To evaluate the pre and post-treatment heart rate and oxygen (O2 ) saturation values measured before, during and after 6MWT in children who received PAH-specific treatment and to determine the effect of these variables on prognosis. Materials and methods: This retrospective study included 29 patients who were diagnosed as PAH and treated. The transcutaneous O2 saturationand heart rate levels were recorded before the test: baseline (Sat0, HR0), at the end of the test: exercise (Sat1, HR1) and 5 min after the test: recovery (Sat2, HR2). The increase in heart rate was defined as HR1-HR0 and the decrease in saturation …
