Development of a Screening Nomogram for Regional Lymph Node Metastasis Development in Muscle Invasive Bladder Cancer after Multiagent Systemic Therapy

This study demonstrates a clinically applicable risk stratification tool for identifying patients at risk for developing lymphadenopathy in T2-4 bladder cancer and may help guide future research in selecting patients eligible for escalation of therapy. Future studies should aim to externally validate this tool within prospective cohorts, and seek to determine if this nomogram may provide further prognostic utility.
