Non-muscle-invasive bladder cancer (NMIBC)

Authored by Open Medicine, published on 2026-05-28 05:11:20.0

Risk-stratified management of NMIBC begins with TURBT, followed by surveillance for low-risk disease and intravesical therapy (BCG preferred) for intermediate- and high-risk tumors. Patients with BCG-unresponsive disease may receive bladder-preserving options such as nadofaragene firadenovec, pembrolizumab, or nogapendekin alfa inbakicept, with radical cystectomy remaining the definitive treatment.

  1. NMIBC
    • TURBT
      • Low grade cTa < 3cm
        • Cystoscopic Surveillance
      • Int & High grade Recurrent LG, HG, T1, CIS
        • TURBT
          Repeat TURBT within ~2–6 weeks after initial resection: • T1 disease (all patients) • High-grade Ta tumors • Any tumor with incomplete initial resection • No muscle in specimen (except clearly low-risk Ta LG)
          • Intravesical BCG (preferred) or Chemo
            • Radical cystectomy
            • Pembrolizumab
              (BCG Refractory with CIS, refusing/ineligible for RC)
            • Nadofaragene firadenovec-vncg
            • Nogapendekin alfa inbakicept
