Due to an advanced understanding of cancer biology and the rapid development of genomic technologies, cancer has shifted from 200 diseases based on pathology (i.e., what a tumor looks like under the microscope) to thousands of diseases based on molecular tumor profiles (i.e., what a tumor looks like when its altered genome is interrogated). Most cancers arise from alterations to the genome, including changes in the number or structure of chromosomes and variations in a single building block of the genetic code.
In Australia, cancer medicine is increasingly guided by our expanding knowledge of cancer genomics (the study of genetic information) and biology. Personalized treatments and targets are often defined by an individual’s genetic profile—known as precision cancer medicine. The translation of genomics-guided precision therapeutics from bench to bedside is beginning to produce real clinical benefits for Australians living with cancer.
Cold atmospheric plasma (CAP) is a safe and effective alternative to radiotherapy for cancer treatment. Its anticancer effects are attributed to increased intracellular reactive oxygen species (ROS). Glutathione, a key antioxidant derived from glutamine, is critical for cell proliferation. This study investigated whether CAP-induced ROS elevation results from reduced glutamine-glutathione conversion and elucidates the underlying mechanisms.
Smokers are at an increased risk of developing mucosal head and neck squamous cell cancers (HNSCCs) and have a worse prognosis when treated. The cellular and molecular mechanisms underlying the latter has not been established. We therefore developed an in vitro model to investigate the effects of radiation and smoking on mucosal HNSCCs.
Immunoneoadjuvant therapy has gained significant attention due to its remarkable advancements in cancer treatment. This study aimed to investigate the molecular mechanisms underlying immunoneoadjuvant therapy through a comprehensive multiomics analysis of samples from a registered clinical trial cohort.
Epidermal Growth Factor Receptor (EGFR) plays a critical role in the development of several cancers. Thus, modulation/inhibition of EGFR activity is an appealing target of developing novel cancer therapeutics.
Congratulations to Indigenous genomics researcher Dr Justine Clark, who is one of two scientists nationally to receive the Australian Academy of Science’s 2024 Aboriginal and Torres Strait Islander Science Award.
Four The Kids Research Institute Australia researchers have received prestigious fellowships and four significant cohort studies led or co-led by The Kids have received key grants under two new funding programs supported by the State Government’s Future Health Research and Innovation (FHRI) Fund.
Cancer prevention and care efforts have been challenged by the COVID-19 pandemic and armed conflicts, resulting in a decline in the global Human Development Index (HDI), particularly in low- and middle-income countries. These challenges and subsequent shifts in health care priorities underscore the need to continuously monitor cancer outcome disparities and statistics globally to ensure delivery of equitable and optimal cancer prevention and care in uncertain times.
Ewing Sarcoma of the pelvis has poorer outcomes than other anatomical sites, with complex anatomy often precluding resection with wide margins. The role of postoperative radiotherapy (RT) in improving outcomes remains undefined. A systematic review using Medline, Embase and Cochrane databases (1972-April 2024) evaluated postoperative RT's impact on local recurrence, event-free survival and overall survival. Twenty-nine retrospective studies (21 to 296 patients) met inclusion criteria, with 28 rated good quality.
