INTRODUCTION: We evaluated long-term outcomes for octogenarians with localised prostate cancer treated using dose-escalated image-guided intensity-modulated radiation therapy (IMRT) at our institution. METHODS: The charts of octogenarians treated for localised prostate cancer were retrospectively reviewed. Overall survival (OS), prostate cancer-specific survival (PCaSS), toxicity rates and changes from baseline were collected. RESULTS: The median follow-up was 97 months...

Air trapping is a common finding radiologists encounter on CT imaging of the thorax. This term is used when there are geographic areas of differing attenuation within the lung parenchyma. Most commonly, this is the result of abnormal retention of air due to complete or partial airway obstruction from small airway pathologies. Perfusional differences due to underlying vascular diseases could also result in these appearances, and hence, inspiratory and full expiratory phase CT studies are required to accurately diagnose air trapping...

INTRODUCTION: Computed tomography (CT) imaging is one of the most commonly used diagnostic tools. Iodine-based contrast media (IBCM) are frequently administered intravenously to improve soft tissue contrast in a wide range of CT scans. Supply chain disruptions triggered by the SARS-CoV-19 pandemic led to a global shortage of IBCM in mid-2022. The purpose of this study was to explore the impact of this shortage on the delivery of healthcare in Western Australia. METHODS: We performed a single-centre retrospective analysis of the provision of CT studies, comparing historical patterns to the shortage period...

INTRODUCTION: The preauricular sulcus is a bony groove seen on the inferior aspect of the iliac bone. It is thought and accepted to be an indicator of female gender. To our knowledge, this study would be the first to examine the sulcal incidence in a multicultural population. To date, there are limited studies to also test the existing hypothesis that the sulcus is only seen in the female gender. The results of this study would be applicable to the field of forensic medicine and gender identification in the post-mortem setting...

INTRODUCTION: Previous studies have demonstrated positive correlations between computed tomography (CT) attenuation of lumbar spine vertebrae and their bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DEXA). However, these studies were performed using a standard 120 kilovoltage peak (kVp) setting. As radiation attenuation in mineralised tissues varies by the tube voltage applied, we determined the diagnostic accuracy of CT attenuation at identifying individuals with low BMD at different kVp settings...

INTRODUCTION: Interventional oncology (IO) is an essential component of cancer care, which has gained substantial recognition in recent years. The aim of this review is to evaluate the level of evidence supporting IO and its inclusion in cancer treatment guidelines. METHODS: A literature search of the PubMed database was performed to identify publication numbers and types for IO treatments published between 2012 and 2022. Selected cancer treatment guidelines and recommendations were reviewed for their inclusion of IO treatments...

INTRODUCTION: Fostering a research culture is a key goal of the Royal Australian and New Zealand College of Radiologists, yet there has never been an organization-wide enquiry into the extent to which this is being realized. The purpose of this work was to address that deficit for the Radiation Oncology (RO) Faculty to serve as a baseline for future comparison. The hypothesis was that such a culture is closer to fact than fantasy. METHODS: With College approval, three de-identified Excel spreadsheets detailing 25 research-related sub-categories of the Faculty's Continuing Professional Development (CPD) database were interrogated for the 2019-21 triennium, accepting that research activity in 2020-21 would be COVID-19 suppressed...

INTRODUCTION: Describing Safety-Related Events (SREs) in a radiotherapy (RT) department and comparing WHO-CFICPS (World Health Organization's Conceptual Framework For The International Classification For Patient Safety) and PRISMA (Prevention and Recovery Information System for Monitoring and Analysis) methods for classifying SREs. METHODS: From February 2017 to October 2020, two Quality Managers (QMs) randomly classified 1173 SREs using 13 incident types of WHO-CFICPS...

INTRODUCTION: Spectral detector computed tomography (SDCT) is a recent advancement that enables elemental material decomposition which could improve the detection of osseous metastases in the oncologic patient. METHODS: Sixteen patients who underwent oncologic staging SDCT as well as WBBS with Technetium-99 m hydroxydiphosphonate (Tc99m HDP) were included in this retrospective study. A total of 50 osseous metastases were identified and confirmed on bone scintigraphy...

Visibility of the tumour and its surroundings during the ablative procedure is crucial for optimal treatment planning, needle placement, ablation zone coverage and postprocedural control. The use of transcatheter CT arteriography providing real-time image guidance has proven to be of additional value for thermal liver ablation. The general advantages of the technique could be of value for other indications and ablation techniques as well, especially when requiring multiple needle placements in the vicinity of precarious vascular structures...

INTRODUCTION: The Royal Australian and New Zealand College of Radiologists (RANZCR) Faculty of Radiation Oncology Genitourinary Group (FROGG) guidelines and online EviQ protocols incorporate prostate-specific membrane antigen (PSMA) positron emission tomography (PET)-guided dose-escalated intensity-modulated radiation therapy (DE-IMRT) for newly diagnosed lymph node (LN) positive prostate cancer. We evaluated late toxicity and efficacy outcomes following the FROGG and EviQ approach. METHODS: Patients with LN-positive-only metastases on PSMA-PET imaging were offered curative therapy with 3 months neoadjuvant androgen deprivation therapy (ADT) followed by DE-IMRT and 3 years adjuvant ADT...

INTRODUCTION: A pacemaker may affect the utility of a mammogram in several ways. The aim of this study is to summarize our institution's experience with mammograms among patients with a cardiac pacemaker, focusing on the diagnostic workup among patients with a newly diagnosed ipsilateral breast cancer. METHODS: A retrospective search of all mammography reports between January 2011 and April 2021 was conducted for identifying cases of patients with a pacemaker. Demographic and clinical characteristics as well as mammography-derived quality parameters and findings were categorized and statistically compared...

INTRODUCTION: To evaluate the role of stereotactic body radiotherapy (SBRT) in hepatocellular carcinoma (HCC) patients with inferior vena cava tumour thrombus (IVCTT) who are not suitable for other loco-regional therapies. METHODS: This is an observational retrospective study done between May 2020 and April 2022. The data of 17 patients who underwent SBRT were collected. Patients of Child-Pugh score (CPS) A5-B7 and along with a liver reserve of ≥700 cc were included...

INTRODUCTION: Many publications have proposed quality standards for stereotactic ablative body radiotherapy (SABR). However, data on the level of compliance with these guidelines is lacking in the literature. This study aimed to understand how these guidelines are applied in the clinic and to identify barriers to implementing such recommendations. METHODS: Interviews were conducted with multidisciplinary staff at radiation oncology centres across New South Wales formulated around the RANZCR Guidelines for Safe Practice of Stereotactic Body (Ablative) Radiation Therapy...
