Is there a role for neoadjuvant therapies followed by radical cystectomy in oligometastatic bladder cancer?

Purpose of review: This review explores the potential role of neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC) for oligometastatic bladder cancer (OMBC) treatment. We focused on extrapolating evidence from studies including lymph node-positive only and metastatic bladder cancer to address the key challenges and therapeutic strategies for OMBC.

Recent findings: Current evidence for NAC and RC in OMBC is limited, with most data derived from studies in locally advanced bladder cancer. NAC has shown efficacy in downstaging and improving survival in patients with locally advanced disease, but its benefits in OMBC remain speculative. Additionally, diagnostic uncertainties, particularly regarding the inclusion of pelvic lymph nodes and the role of FDG-PET/CT, pose significant challenges to accurate staging and treatment decisions. Recent studies highlight the potential of metastasis-directed therapy, but uncertainties remain on patient selection and treatment protocols for OMBC.

Summary: There is need for prospective studies to evaluate neoadjuvant systemic treatments and RC specifically in OMBC. Moreover, resolving current diagnostic challenges is crucial to avoid undertreatment due to inaccurate staging. Until more concrete evidence emerges, changes to standard treatment protocols should be approached with caution and offered only within trials.
