Published on: August 19, 2021

  • Lymph node status is a primary prognostic factor in bladder cancer.
  • Histologic and molecular techniques offer high sensitivity and specificity for identifying lymph node metastasis.
  • These advanced methods may surpass standard pathological evaluation.

    • Conclusions:

    • Current staging methods may underestimate bladder cancer metastasis.
    • Advanced histologic and molecular techniques hold potential for more accurate staging.
    • Further research is needed to define the clinical utility of these methods for bladder cancer patients.
