Percutaneous cryoablation versus partial nephrectomy for cT1b renal tumors: An inverse probability weight analysis

Clinical and Oncological Outcomes Following Percutaneous Cryoablation vs. Partial Nephrectomy for Clinical T1 Renal Tumours: Systematic Review and Meta-Analysis

“…Full-text reviews were performed for the remaining 95 articles. Ultimately, 81 papers were excluded (other than percutaneous cryoablation technique, single-arm studies, studies reporting no single outcome of interest or studies with overlapping cohorts), leaving 14 studies included in the present systematic review and meta-analysis [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

“…The available records were published from 2017 to 2023. Seven out of fourteen studies [ 14 , 15 , 16 , 17 , 18 , 21 , 22 ] presented data for European populations, followed by four [ 11 , 19 , 23 , 24 ] and three [ 12 , 13 , 20 ] papers conducted in Japan and the United States, respectively. The vast majority of studies had retrospective designs [ 11 , 12 , 13 , 14 , 15 , 17 , 19 , 20 , 22 , 23 , 24 ].…”

In six articles [ 11 , 12 , 13 , 14 , 18 , 20 ], PN was performed using either an open or minimally invasive (laparoscopic or robotic) approach, while six [ 16 , 17 , 19 , 21 , 22 , 23 ] and two [ 15 , 24 ] trials included patients undergoing only robotic and laparoscopic PN, respectively.…”

“…The majority of publications [ 13 , 14 , 16 , 17 , 18 , 19 , 23 , 24 ] focused on individuals with either cT1a or cT1b renal tumours, yet the proportion of cT1b renal masses was relatively low in these investigations. Clinical data and outcomes for both cT1a and cT1b renal cell tumours were reported separately in 2 out of 14 articles [ 12 , 15 ], while 2 articles [ 11 , 22 ] analysed only patients with cT1b tumours and 1 article [ 21 ] exclusively analysed patients with cT1a tumours. A male predominance was observed in all studies.…”
