Migration of tattoo pigment to axillary lymph nodes mimicking calcifications is a recognized phenomenon, however, pigment in an intra-mammary node masquerading as a breast mass is a rare complication of cosmetic tattoos. As the prevalence of tattooing increases among women presenting to Breastscreen, radiologists may expect to encounter this lesion mimicking a breast neoplasm. We present a 50-year-old female with extensive tattoos on her arms, chest wall and abdomen, recalled for a small calcified breast mass on her first screening mammogram...

Prostate cancer remains one of the leading causes of cancer-related death in the world. There have been significant advances in chemotherapy, hormonal therapy and targeted therapy options for patients with castrate-resistant disease. However, these systemic treatments are often associated with unwanted toxicities. Targeted therapy with radiopharmaceuticals has become of key interest to limit systemic toxicity and provides a more precision oncology approach to treatment. Strontium-89, Samarium-153 EDTMP and Radium-223 have been trialled with mixed results...

INTRODUCTION: Patients with squamous cell carcinoma of the head and neck (HNSCC) often receive post-operative radiotherapy (RT). A package time between surgery and completion of RT of ≤100 days is associated with lower recurrence and longer survival. In this study, we investigate the impact of outside referral and dental extractions on package time, with secondary detriment to relapse-free survival (RFS) and overall survival (OS). METHODS: We conducted a retrospective chart review on patients with HNSCC who received primary surgical resection at an academic medical centre...

INTRODUCTION: Uterine artery embolization is performed in pre-menopausal women. Understanding the contribution of radiation dose at each stage of the procedure is important for potential dose reduction. The aim was to retrospectively analyse radiation dose on a per-procedural-stage basis, comparing digital subtraction angiography (DSA) and conventional roadmap (CRM). METHODS: Group A consisted of 50 patients where DSA was used for road mapping at all stages: (I) Aortogram, (II) Left internal iliac artery (IIA) DSA, (III) Left uterine artery (UA) DSA, (IV) Right IIA DSA and (V) Right UA DSA...

Palliative radiotherapy (RT) effectively relieves pain in patients with bone metastases (BMs). Furthermore, several clinical trials, in most cases conducted in high-income countries (HICs), proved that single-fraction RT is equally effective compared to multi-fractionated RT. However, the evidence is scarce regarding low/middle-income countries (LMICs), where the diagnosis of BMs could be later and RT techniques less advanced. Therefore, we conducted a systematic literature review to evaluate the efficacy of palliative RT of BMs in the LMIC setting...

INTRODUCTION: Palliative radiotherapy (PRT) is frequently used to treat symptoms of advanced cancer, however benefits are questionable when life expectancy is limited. The 30-day mortality rate after PRT is a potential quality indicator, and results from a recent meta-analysis suggest a benchmark of 16% as an upper limit. In this population-based study from Queensland, Australia, we examined 30-day mortality rates following PRT and factors associated with decreased life expectancy. METHODS: Retrospective population data from Queensland Oncology Repository was used...
