“…Large (> 3 cm) or endophytic RCC is more likely to progress locally or lead to reduced recurrence-free survival rates (1, 2, 13). The median tumor size (2.1 cm) of our study was smaller than those of previously reported studies (1,2,3,4). However, the percentage of endophytic tumors in our study was greater than those of previously reported studies (2, 13).…”

“…Zagoria et al (1) and other groups (2,3,4) have reported that recurrence-free survival rates were 100% and 92.3–95.4% after RFA treatment for T1a RCC, respectively. However, the number of T1a RCCs in the Zagoria study (1) was smaller than those of the other groups (2,3,4). Two-year recurrence-free survival rate is a mid-term outcome, and is not equivalent to the five-year recurrence-free survival rate.…”

ObjectiveTo evaluate the mid-term outcomes of percutaneous radiofrequency ablation (RFA) treatment in patients with small (< 4 cm) renal cell carcinoma (RCC) in Korea.Materials and MethodsBetween 2010 and 2015, 51 patients (40 men and 11 women; median age, 57 years) with biopsyproven 51 RCC were treated using CT-guided RFA. All patients were clinically staged T1aN0M0 prior to RFA. The median tumor size and follow-up period were 2.1 cm (range, 1.0–3.9 cm) and 26 months (4–60 months), respectively. Local tumor progression, distant metastasis, primary and secondary effectiveness rates, and major complication rates were recorded. Estimated glomerular filtration rates (GFRs) between pre-RFA and last follow-up were compared using paired t tests. The 2-year recurrence-free survival rate was calculated using Kaplan-Meier survival analysis.ResultsOf the 51 patients, 2 (3.9%) experienced local tumor progression, and 1 (2.0%) had lymph node metastasis after the first RFA session. Primary and secondary effectiveness rates were 96.1% (49/51) and 100% (1/1), respectively. Only 1 patient experienced a major complication (uretero-pelvic stricture) after the second RFA session for treating a local tumor progression, and the major complication rate was 1.9% (1/52). The median pre-RFA and last follow-up GFRs were 87.1 mL/ min/1.73 m2 (14.2–142.7 mL/min/1.73 m2) and 72.0 mL/min/1.73 m2 (7.2–112.6 mL/min/1.73 m2), respectively (p < 0.0001). The 2-year recurrence-free survival rate was 96.0%.ConclusionCT-guided RFA is a safe and effective treatment in Korean patients with T1a RCC because of excellent mid-term outcomes.

“…[1][2][3][4] Among those management options, LTA may be undertaken and, according to recent reports, provide adequate oncological outcomes. 5,6 Also, different LTA types of energy (for example, cryoablation, radiofrequency, or microwaves) and approaches (percutaneous, laparoscopic, or open) can be chosen depending on the institution's experience.…”

Introduction: Local tumour ablation (LTA) is a recommended option for the treatment of localized kidney cancer in nonsurgical candidates. We performed a survey to describe the practice patterns of this procedure in Canada. Methods: An electronic survey was sent by email to all urologists registered to the Canadian Urological Association (CUA). Urologists were queried about general demographic information, LTA availability at their institution (and reasons for non-availability, if it was the case), as well as the type and context of LTA use. Results: Overall, 103 individual responses were obtained (response rate of 19.5%). Of those, 58 (56.3%) had access to LTA at their institution. Urologists who had access to LTA were more likely to work at an academic institution (69 vs. 16%, p<0.001). Among individuals who did not use LTA, the main reasons were lack of staff, such as radiologists, who can assist and/or perform the procedure (64%); and lack of expertise with the procedure (62%). Among urologists who had access to LTA, percutaneous radiofrequency and cryoablation were the most commonly used (72% and 21%, respectively); however, urologists were rarely involved in those procedures (12%). Conclusions:In this national survey, we found that a significant proportion of Canadian urologists did not have access to LTA. We also found that when LTA was performed, urologists were rarely involved in the procedures. Those findings represent significant areas for improvement in the access to LTA. The conclusions of this study are limited by the low response rate.
