Summary
A second endoscopic resection is crucial for pT1 bladder tumors to detect residual cancer before treatment. This procedure helps ensure complete tumor removal and accurate staging, improving patient outcomes.
Area of Science:
- Urology
- Oncology
- Pathology
Context:
- pT1 bladder tumors require accurate staging for effective treatment.
- Endoscopic resection is a primary treatment modality for non-muscle-invasive bladder cancer.
- Residual tumor after initial resection can lead to understaging and suboptimal treatment.
Purpose:
- To determine the rate of residual pT1 bladder tumors after initial endoscopic resection.
- To assess the efficacy of a second endoscopic resection in detecting residual disease.
- To evaluate the necessity of a second resection for accurate staging before intravesical therapy.
Summary:
- A second endoscopic resection was performed on 52 patients with pT1 bladder tumors.
- Residual tumor was found in 36.5% of patients during the second resection.
- Residual disease was more common in multifocal tumors and when procedures were performed by junior surgeons.
Impact:
- A second endoscopic resection is essential for confirming the absence of residual tumor before initiating conservative treatment for pT1 bladder cancer.
- This approach aids in definitively excluding muscle invasion, crucial for treatment planning.
- Findings highlight the importance of surgical experience and tumor characteristics in resection outcomes.
