Abstract

fetched live from OpenAlex

To conduct a meta-analysis assessing the perioperative, functional and oncological outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) for T1b tumours. The primary endpoints were the oncological outcomes. The secondary endpoints were the perioperative and functional outcomes. A systematic literature review was performed by searching multiple databases through February 2019 to identify eligible comparative studies according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. Identified reports were assessed according to the Newcastle-Ottawa Scale for nonrandomized controlled trials. Overall, 13 retrospective cohort studies were included in the analysis. Patients undergoing PN were younger (weighted mean difference [WMD] −3.49 years, 95% confidence interval [CI] −5.16 to −1.82; p<0.0001) and had smaller masses (WMD −0.45 cm, 95% CI −0.59 to −0.31; p<0.0001). There were no differences in the oncological outcome, which was demonstrated by progression-free survival (hazard ratio [HR] 0.70; p=0.22), cancer-specific mortality (HR 0.91; p=0.57) and all-cause mortality (HR 1.01; p=0.96). The two procedures were similar in estimated blood loss (WMD −16.47 mL; p=0.53) and postoperative complications (risk ratio [RR] 1.32; p=0.10), and PN provided better renal function preservation and was related to a lower likelihood of chronic kidney disease onset (RR 0.38; p=0.006). PN is an effective treatment for T1b tumours because it offers similar surgical morbidity, equivalent cancer control, and better renal preservation compared to RN.

Full frame distilled prediction

Teacher imitation

Not 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.
