First seen Jan 19, 2026 · Last updated Apr 29, 2026 · Updated 16 times

Summary

This study tested a new way to remove early-stage bladder tumors called En Bloc resection, where the tumor is taken out in one piece instead of in fragments. The goal was to see if this method gives doctors better tissue samples and more accurate diagnosis, which could lower the chance of the cancer coming back. The trial involved 220 adults with bladder tumors between 1 and 6 cm, comparing the new technique to standard surgery.
