“…8 MWA also had the benefit of shorter procedural and ablation times compared to the cryoablation and RFA groups. A systematic review and meta-analysis of comparison studies comparing efficacy and safety of MWA against RFA and cryoablation was undertaken by Castellana et al 9 The study included a total of 2258 thermal ablations and concluded that MWA is as effective and safe as RFA and cryoablation in addition to encountering fewer recurrences. A systematic review by McClure et al 10 also found MWA had lower 1-year local recurrence rates, shorter ablation times with similar complication rates.…”

“…6,7 There have also been a number of systematic reviews, meta-analyses and retrospective cohort studies demonstrating either superior or similar cancer-related outcomes and lower complication rates in MWA for RCCs when compared to RFA and cryoablations. [8][9][10] The RENAL nephrometry score is a system used to describe tumour anatomy and complexity and has been used as a tool to aid perioperative decision-making and to predict long-term outcomes. Using this scoring system, the tumour can be classified into low complexity (score 4-6), moderate complexity (score 7-9) and high complexity (score [10][11][12].…”

IntroductionPartial nephrectomy is currently the preferred treatment option for T1a renal cell carcinomas (RCC), with nephron‐sparing techniques, including microwave ablation, becoming more common in select patients. Primary aims are to document outcomes of microwave ablation for T1a RCCs in an Australian tertiary centre to add to the evidence for its safety and efficacy.MethodsThe prospectively maintained Sir Charles Gairdner Hospital Interventional Radiology database was retrospectively searched for all Renal Microwave ablations completed between June 2012 and February 2022. This database and a combination of hospital programmes including Agfa Impax PACS, Bossnet digital medical record and iSoft Clinical Manager were used to extract the relevant data which was anonymized and entered into an Excel spreadsheet for analysis.ResultsForty‐eight patients underwent microwave ablation for 50 tumours. Of these, there were two local and two distant recurrences. A fifth patient had metastases on presentation. Higher local recurrence rates were associated with larger tumour size (P = 0.043). Tumour proximity to the collecting system <4 mm was associated with higher rates of complications (P = 0.020). RENAL scores did not show statistically significant correlation with complications (P = 0.092) or local or distant recurrence. Notably, the study follow‐up time was longer than many comparative studies (mean = 2796, ~7.66 years censoring for death and mean = 832 days, ~2.28 years not censoring for death).ConclusionConsistent with the literature, this study further demonstrates that microwave ablation is a safe and efficacious option for treatment of T1a RCC.
