    Abstract Introduction: Current literature suggests that axial skeleton magnetic resonance imaging (AS-MRI) is more sensitive than Tc 99m bone scintigraphy (BS) for detecting bone metastases (BM) in high-risk prostate cancer (PCa). However, BS is still widely performed. Its diagnostic accuracy has been studied; however, its feasibility and cost implications are yet to be examined.
    Methods: We reviewed all patients with high risk PCa undergoing AS-MRI over a 5-year period. AS-MRI was performed on patients with histologically confirmed PCa and either PSA > 20 ng/ml, Gleason ≥8, or TNM Stage ≥T3 or N1 disease. All AS-MRI studies were obtained using a 1.5-T AchievaPhilips™MRI scanner. We compared the AS-MRI positivity and equivocal rate with that of BS. Data were analysed according to Gleason score, T-stage and PSA. Multivariate logistic regression analyses were used to quantify the strength of association between positive scans and clinical variables. Feasibility and burden of expenditure was also evaluated.
    Results: Five hundred three patients with a median age of 72 and a mean PSA of 34.8 ng/ml were analysed. Eighty-eight patients (17.5%) were positive for BM on AS-MRI (mean PSA 99 [95% CI 69.1-129.9]). Comparatively 409 patients (81.3%) were negative for BM on AS-MRI (mean PSA 24.7 (95% CI [21.7-27.7]) (
    Conclusion: The use of AS-MRI to stage BM in high-risk PCa is both feasible and results in a reduced burden of expenditure.

    Abstract Introduction: To present the oncological outcomes in a series of patients with cT1a renal cell carcinoma (RCC) treated with radiofrequency ablation (RFA) and its effect on the glomerular filtration rate (GFR).
    Materials and methods: Forty-five patients (48 renal units) treated at the Belfast City Hospital, over 4 years. Average age is 61.5 years (range 41-80). Eighteen patients (22 renal units) were included with American Society of Anesthesiologists (ASA) II and III. The rest were ASA I. Average tumor size was 2.63 cm (range 1.2 cm-6 cm). Renal function before and after RFA was recorded by means of the estimated glomerular filtration rate (eGFR) and the changes are presented. Oncological outcomes were established from follow up imaging. A satisfactory response was defined by disappearance or a persistence of non-enhancing lesion of smaller size at follow up. A partial response was defined by a persistent but non-enhancing similar size lesion. A failed response was defined by enlarging or persistently enhancing lesions.
    Results: Mean follow up was 30.6 months (4-60 months). A good response was found in 33 (74%) patients. A partial response was found in 3 (8%) patients and failed response was identified in 8 (18%) patients. The average reduction in eGFR was 11 mL/min. Two patients had a 50% reduction in their eGFR. No patient required dialysis following treatment.
    Conclusion: RFA presents safe treatment choice for patients with RCC, particularly those that are high risk surgical candidates and those who refuse surgery. Short term results suggest good oncological outcomes and preservation of renal function.
