RESUMO
INTRODUCTION: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality and transarterial chemoembolisation (TACE) is an established technique to treat patients with intermediate-stage HCC. The aim of this study was to generate accurate costing data on cTACE and DEB-TACE in an Australian setting and assess whether one of the procedures offers favourable cost-effectiveness. METHODS: Costing study using data from all TACE procedures performed at a single centre between January 2018 and December 2022. Data were included from all direct and indirect costs including operative costs, wages, overheads, ward costs, transfusion, pathology, pharmacy and ward support. Cost-effectiveness was assessed by dividing local costs by existing high-quality data on quality-adjusted life years (QALYs). RESULTS: 64 TACE treatments were performed on 44 patients. Mean age was 66.5 years and 91% were male. Overall median total cost per patient for the entire TACE treatment regime was AUD$7380 (range AUD$3719-$20,258). However, 39% of patients received more than one treatment, and the median cost per individual treatment was AUD$5270 (range AUD$3533-$15,818). The difference in median cost between cTACE (AUD$4978) and DEB-TACE (AUD$9202) was significant, P < 0.001. In calculating cost-effectiveness, each cTACE treatment cost AUD$2489 per QALY gained, while each DEB-TACE cost AUD$3834 per QALY gained. The incremental cost-effectiveness ratio (ICER) for DEB-TACE over cTACE was AUD$10,560 per QALY gained. CONCLUSION: Both cTACE and DEB-TACE are low-cost treatments in Australia. However, DEB-TACE offers a solution with an ICER of AUD$10,560 per QALY gained which is below the Australian government willingness to pay threshold and thus is a more cost-effective treatment.
RESUMO
Lymphomas are a heterogenous group of cancers of the lymphatic system in which disease primarily arises in lymph nodes. Extranodal disease is common; however, musculoskeletal involvement is rare. Imaging plays an important role in the diagnosis and staging of all lymphomas. In this case series, we present examples of musculoskeletal involvement of lymphoma encountered at our institution. We outline the clinical presentation and imaging findings of each and use these cases to review the features that can help to differentiate lymphoma from other musculoskeletal lesions.
RESUMO
Xanthogranulomatous Pyelonephritis (XGP) is a rare, chronic granulomatous inflammatory condition thought to arise secondary to a combination of obstruction, recurrent bacterial infection and an incomplete immune response resulting in focal or diffuse renal destruction. This destruction may be profound with the potential to infiltrate surrounding tissues and viscera. The imaging features of XGP can be ambiguous, mimicking malignancy, tuberculosis (TB) and malakoplakia earning the title of "the great imitator". Computed tomography (CT) is the mainstay of XGP diagnosis and staging, accurately quantifying the stone burden and staging the renal destruction, including the extent of extra-renal spread. Although some cases in children have been successfully treated with antibiotics alone, nephrectomy remains the most common treatment for XGP in adults. The specific management strategy needs to be tailored to individual patients given the potential constellation of renal and extrarenal abnormalities. Although XGP has classically required open nephrectomy, laparoscopic nephrectomy has an increasing role to play arising from the advancement in laparoscopic skills, technique and instruments. Nephron-sparing partial nephrectomy may be considered in the focal form. Interventional radiology techniques most often play a supportive role, eg, in the initial drainage of associated abscesses, but have rarely achieved renal salvage. This narrative review seeks to synthesise the existing literature and summarise the radiological approach and interventional radiology management situated in a clinical context.
