INTRODUCTION: Despite 3% of Australians identifying as Indigenous, cutaneous malignancies in these patients, including incidence, risk factors and outcomes have not been investigated. This is despite recognition that cancer outcomes in this population are significantly poorer. METHODS: We undertook a retrospective case series of Indigenous Peoples who presented to two urban cancer therapy centres for the management of cutaneous malignancies from 2003 to 2017. Risk factors, tumour-specific characteristics, treatments and outcomes were reviewed...

INTRODUCTION: Breast and chest wall desmoid tumours can cause debilitating symptoms and deformity. The mutilating effects of surgical treatment have prompted a shift to medical treatments and even to a wait-and-see approach. This study sought to highlight specific characteristics of breast and chest wall desmoid tumours on long-term follow-up by sequential MRI scans. METHODS: Thirty-two breast MRI scans from six patients with chest wall or breast desmoid tumours followed up for up to 6 years were retrospectively reviewed...

Vijay Mistry, Arani Halder, Nivene Saad
Perineal hernias are rare, protruding through a defect, congenital or acquired, of the pelvic floor musculature with intraperitoneal or extraperitoneal content. Anatomically they can be classified as anterior and posterior based on the position relative to the superficial transverse perineal muscle. We present a case of a rare primary posterior perineal hernia that was identified incidentally on computed tomography.

INTRODUCTION: The aim of this study was to determine the relationship between the way breast cancer is diagnosed and its prognostic features. METHODS: We studied new primary invasive and non-invasive breast cancers (670) diagnosed between 2013 and 2015 where detection included at least clinical examination, mammography and breast ultrasound (BUS). The cancers were classified into six Diagnostic Groups according to the results of each modality. RESULTS: Overall, 79% of cancers were positive on mammography, but another 20% were diagnosed on BUS after a negative mammogram...

INTRODUCTION: To evaluate the accuracy of deep convolutional neural networks (DCNNs) for detecting neck of femur (NoF) fractures on radiographs, in comparison with perceptual training in medically-naïve individuals. METHODS: This study extends a previous study that conducted perceptual training in medically-naïve individuals for the detection of NoF fractures on a variety of dataset sizes. The same anteroposterior hip radiograph dataset was used to train two DCNNs (AlexNet and GoogLeNet) to detect NoF fractures...

INTRODUCTION: Stroke caused by basilar artery occlusion (BAO) is a rare but potentially devastating neurological condition, with poor outcomes and high mortality rates, approaching 70-90%. Success of intravenous and intra-arterial thrombolysis in BAO is variable, leading to Endovascular Therapy (EVT) being utilized to a greater degree in this clinical setting. We investigate the use of EVT in BAO with regard to success of revascularization and patient mortality/outcome. METHODS: Retrospective patient data was collected from medical records and radiology information systems...

INTRODUCTION: To report a series of patients with osteoid osteoma treated by radiofrequency ablation in whom no complications or recurrences occurred. METHODS: Over a 13-year period, 32 consecutive patients with osteoid osteoma were treated by radiofrequency ablation in an Australasian teaching centre. RESULTS: All patients had resolution of symptoms with no complication or recurrence. CONCLUSIONS: This series is further evidence for the use of radiofrequency ablation as the primary treatment for osteoid osteoma...

REVIEW
Rebecca M Woodward, Marc J Philippon
Hip arthroscopy is one of the most rapidly growing and evolving orthopaedic subspecialties. With the recent dramatic increase in the volume of hip arthroscopy performed there has been an increase in the number of symptomatic patients following arthroscopy for femoroacetabular impingement. Imaging has a key role in determining the need for revision surgery and in preoperative planning. Although the revision rate for hip arthroscopy is 3-9%, little has been published about the imaging findings associated with unsatisfactory treatment outcomes...

The retroperitoneal space is made up of multiple communicating compartments. Here we detail an unusual case of ectopic gas almost exclusively isolated to the properitoneal space, a space in communication with the retroperitoneum. This case is a reminder that when extraperitoneal gas is identified, the retroperitoneal structures should be interrogated carefully to identify a cause.

INTRODUCTION: The aim of this study is to evaluate the use of androgen deprivation therapy (ADT) with post-prostatectomy radiotherapy (PPRT) in a population-based cohort of Australian men. METHODS: This is a prospective cohort of men with localised prostate cancer captured in the Prostate Cancer Outcomes Registry Victoria (PCOR-Vic), who received PPRT between January 2010 and December 2015. The primary outcome was ADT use with PPRT. Multivariate logistic regressions were used to identify patient, tumour and institutional factors influencing ADT use...

INTRODUCTION: Interventional Radiology procedures can provoke anxiety and may be painful. Current practice, Radiologist Controlled Sedation (RCS), involves titrating aliquots of midazolam and fentanyl to patient response but underdosing and overdosing may occur. This study tests a new method of titrating sedation/analgesia during the procedure, Patient Controlled Sedation (PCS), in which a combination of fentanyl and midazolam are administered using a patient-controlled analgesia pump...

INTRODUCTION: Stereotactic ablative radiotherapy (SABR) is a guideline-recommended treatment for inoperable stage I non-small cell lung cancer (NSCLC), but imaging assessment of response after SABR is difficult. The goal of this study was to evaluate imaging-based biomarkers of tumour response using dynamic 18 F-FDG-PET and CT perfusion (CTP). METHODS: Thirty-one patients with early-stage NSCLC participated in this prospective correlative study. Each underwent dynamic 18 F-FDG-PET/CTP studies on a PET/CT scanner pre- and 8 weeks post-SABR...

INTRODUCTION: Curative radiotherapy is guideline treatment for inoperable patients of good performance status with Stage I & II Non-Small Cell Lung Cancer (NSCLC). The aim of this study was to evaluate radiotherapy patterns of care in these patients, the reasons for palliative treatment and the proportion of patients suitable for curative stereotactic ablative body radiotherapy (SABR). METHODS: Electronic oncology databases at three institutions were queried to retrieve data on patients with inoperable Stage I & II NSCLC seen in radiation oncology clinics between 1/1/2008 and 31/12/2014...

REVIEW
Harriet E Gee, Lauren Moses, Kirsty Stuart, Najmun Nahar, Ken Tiver, Tim Wang, Rachel Ward, Verity Ahern
Adequate coverage of sites harbouring potential microscopic disease is paramount, where the clinical decision has been made to include regional lymph node radiotherapy for patients with breast cancer. This must be achieved in balance with minimising dose to normal tissues. Several international consensus guidelines detailing clinical target volumes (CTVs) are available, but there is currently no agreement as to which is most appropriate for a given clinical situation. Contouring guidelines are beneficial for routine practice and essential for clinical trial quality assurance...

INTRODUCTION: Ventilation perfusion single photon emission computed tomography (V/Q SPECT) and CTPA are the two leading imaging studies used to investigate acute pulmonary embolism. V/Q SPECT is often the first line investigation for pregnant patients and young females. Historically, V/Q Planar studies have high rates of indeterminate findings resulting in a preference for CTPA studies. The purpose of this research is to examine current V/Q SPECT referral practices in the quaternary clinical setting and to confirm V/Q SPECT studies have low rates of equivocal findings...

Neurofibromatosis type 1 (NF1) is a multisystem phakomatosis. The intrathoracic manifestations of NF1 are protean. We describe a rare case of a plexiform neurofibroma infiltrating the mediastinum and lungs with multiple endobronchial neurofibromata. To our knowledge, a mediastinal plexiform neurofibroma extending into the lungs on CT has not been reported.
