Indication for a Single Postoperative Instillation of Chemotherapy in Non-muscle-invasive Bladder Cancer: What Factors Should Be Considered?
Overview
abstract
An early single instillation of intravesical chemotherapy (SICI) used immediately after transurethral resection of the bladder (TURB) can significantly reduce the recurrence rate in selected patients with non-muscle-invasive bladder cancer (NMIBC). SICI should be used in patients with low-risk and with selected intermediate-risk tumours, in particular for multiple primary small papillary tumours, single primary papillary tumours >3cm, and single recurrent papillary tumours recurring >1yr after the previous resection. The available data do not support any recommendation to reduce the role of SICI in patients after fluorescence cystoscopy-guided TURB or en bloc TURB. SICI can even provide some benefit in patients with intermediate-risk tumours subsequently treated with further instillations. During instillation, contraindications should be taken into account and safety measures should be applied. PATIENT SUMMARY: An early single instillation of intravesical chemotherapy immediately after transurethral resection of the bladder can significantly reduce the recurrence rate in selected patients with non-muscle-invasive bladder cancer. It should be used in patients with low-risk and selected intermediate-risk tumours.
