The study found that only tumor stage and proliferation rate, measured by the mitotic index, significantly predict outcomes in nodular bladder cancer. These factors are crucial for understanding bladder cancer progression and survival.

Area of Science:

  • Urology
  • Oncology
  • Pathology

Background:

  • Nodular transitional cell carcinoma (TCC) is a subtype of bladder cancer.
  • Accurate prognostic factors are essential for managing bladder cancer patients.

Purpose of the Study:

  • To evaluate the prognostic significance of clinical stage, WHO grade, nuclear morphometry, and mitotic index in nodular TCC.
  • To identify predictors of tumor progression and patient survival.

Main Methods:

  • A cohort of 106 nodular TCC cases were followed for a mean of 9 years.
  • Clinical stage, WHO grade, six nuclear factors, and volume-corrected mitotic index (M/V index) were analyzed.
  • Correlation with progression and survival was assessed.

Main Results:

  • The M/V index strongly correlated with WHO grade.
  • WHO grade independently predicted progression in N- and M-categories.
  • Tumor stage (T-category), N-category, M-category, and M/V index predicted survival.
  • In T1-T2N0M0 tumors, Dmax and M/V index predicted survival.
  • Multivariate analysis confirmed T-category and M/V index as independent prognostic factors.

Conclusions:

  • Tumor stage and proliferation rate (M/V index) are key independent prognostic indicators in nodular TCC.
  • These factors are crucial for predicting patient survival and guiding treatment decisions.
