Assessing the impact of the absence of detrusor muscle in ta low-grade urothelial carcinoma of the bladder on recurrence-free survival
Background: Obtaining detrusor muscle (DM) in transurethral resection of bladder tumor (TURBt) specimen is considered a surrogate marker of resection quality. However, evidence was principally investigated in high-risk tumors. Therefore, DM sampling for low-grade (LG) urothelial carcinoma (UC) remains poorly investigated and certainly requires further investigation.
Objective: To assess whether the absence of DM in TURBt specimen has a negative impact on recurrence-free survival (RFS) in patients with a Ta LG UC.
