Improving bladder-sparing treatment for muscle-invasive bladder cancer by targeting DNA repair changes

Targeting Nucleotide Excision Repair Deficiency to Improve Bladder Sparing Treatment for Muscle Invasive Bladder Cancer

NIH-funded research Dana-Farber Cancer Inst · NIH-11162292

This work looks at whether bladder cancers with specific DNA-repair gene changes make bladder-preserving chemo-and-radiation more effective so more patients can avoid bladder removal.

What this research studies

If you have muscle-invasive bladder cancer, the team will look for changes in a DNA-repair gene called ERCC2 in tumor tissue. They will compare how tumors with ERCC2 changes respond to standard cisplatin-based chemoradiotherapy versus tumors without those changes, using patient tumor samples and clinical outcome data. In lab models they will also test how ERCC2-deficient bladder cancer cells react to chemotherapy and radiation to understand why responses differ. The goal is to find a molecular marker that could help doctors and patients choose bladder-sparing treatment when it's likely to work.

Who could benefit from this research

Good fit: People with newly diagnosed muscle-invasive bladder cancer who can provide tumor tissue and are weighing bladder-preserving chemoradiotherapy versus cystectomy are the ideal candidates.

Not a fit: Patients with non-muscle-invasive disease, widely metastatic bladder cancer, or tumors without ERCC2 changes may not benefit from this specific approach.

Why it matters

Potential benefit: If successful, this could help identify patients who can safely keep their bladder by choosing chemoradiation instead of bladder removal.

How similar studies have performed: Previous work showed ERCC2 mutations make bladder tumors more sensitive to cisplatin chemotherapy, but using that marker to guide combined chemo‑radiation decisions is a novel step.
