Abstract
PURPOSE: We aimed to compare local and metastatic recurrence of small renal masses primarily treated by cryoablation or microwave ablation. MATERIALS AND METHODS: The MEDLINE, CINAHL, and PUBMED databases were searched to review the treatment of small renal masses with cryoablation or microwave ablation. Fifty-one studies met the inclusion criteria. RESULTS: Fifty-one studies representing 3950 kidney lesions were analyzed. No differences were detected in the mean patient age (P = 0.150) or duration of follow-up (P = 0.070). The mean tumor size was significantly larger in the microwave ablation group compared with the cryoablation group (P = 0.030). There was no difference between microwave ablation and cryoablation groups in terms of primary effectiveness (93.75% vs. 91.27%, respectively; P = 0.400), cancer-specific survival (98.27% vs. 96.8%, respectively; P = 0.470), local tumor progression (4.07% vs. 2.53%, respectively; P = 0.460), or progression to metastatic disease (0.8% vs. 0%, respectively; P = 0.120). Patient age was predictive of overall complications in the multivariate analysis (P = 0.020). Local tumor progression with cryoablation was predicted by the mean follow-up duration using univariate (P = 0.009) and multivariate regression (P = 0.003). Clear cell and angiomyolipoma were more frequent in the microwave ablation group (P < 0.0001 and P = 0.03328, respectively), and papillary, chromophobe, and oncocytoma were more frequent in the cryoablation group (P < 0.0001, P < 0.0001, and P = 0.0004, respectively). Open access was used more often in the microwave ablation group than in the cryoablation group (12.20% vs. 1.04%, respectively; P < 0.0001), and percutaneous access was used more frequently in the cryoablation group than in the microwave ablation group (88.64% vs. 37.20%, respectively; P = 0.0021). CONCLUSION: There is no difference in local or metastatic recurrence between cryoablation- and microwave ablation-treated small renal masses.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
