Saving the bladder in advanced bladder cancer with variant cell types

This trial is testing a three-part approach called trimodal therapy for patients with advanced bladder cancer that has variant histology (uncommon cell types mixed with typical bladder cancer cells). The treatment combines chemotherapy given before surgery, followed by a procedure to remove the tumor, and then chemotherapy given at the same time as radiation therapy. The goal is to shrink and control the cancer while keeping your bladder instead of removing it surgically.

Most bladder cancer research focuses on patients with typical bladder cancer cells, but some patients have rarer variants of bladder cancer cells. There is very little information about whether the new treatment works well for these variant types, so this study aims to fill that knowledge gap.
