Predictive Factorsfor Final Pathologic Ureteral Sections

Completed

• Conditions: Urothelial Carcinoma

• Registration Number: NCT03677544
• Lead Sponsor: Centre Hospitalier Universitaire, Amiens

Brief Summary

To identify preoperative predictive factors for final ureteral section invasion after radical cystotomie (RC) and to validate significant factors on an external independent cohort. The investigators retrospectively reviewed data of all consecutive RC performed for bladder cancer in 2 high-volume institutions. Clinical, pathological, and follow-up data were collected prospectively and reviewed retrospectively. Pathological evaluation was performed by 2 well-trained uropathologists in each center. Logistic regression analyses were performed to identify predictive factors for final ureteral sections involvement. Significant factors in cohort A were validated in cohort B. Receiver operating curve and area under curve were modeled to evaluate predictive accuracy of the markers

Detailed Description

To identify preoperative predictive factors for final ureteral section invasion after radical cystotomie (RC) and to validate significant factors on an external independent cohort. Pathological evaluation was performed by 2 well-trained uropathologists in each center (Y.A. and C.C). The investigators retrospectively reviewed data of all consecutive RC performed for bladder cancer in 2 high-volume institutions. Clinical, pathological, and follow-up data were collected prospectively and reviewed retrospectively. Pathological evaluation was performed by 2 well-trained uropathologists in each center. Logistic regression analyses were performed to identify predictive factors for final ureteral sections involvement. Significant factors in cohort A were validated in cohort B. Receiver operating curve and area under curve were modeled to evaluate predictive accuracy of the markers
