Dissecting patterns of care in patients with variant histology of bladder cancer and lymph node invasion

Objectives Lymph node invasion (LNI) is related to long-term survival in patients with muscle-invasive bladder cancer. However, in the case of variant histology (VH), data on pelvic lymph node dissection (PLND) and LNI are sparse. We described the pattern of care of PLND in patients with VHs of bladder cancer, exploring predictors of LNI. Methods Using the 2001–2016 SEER registry, 20 767 bladder cancer patients who underwent PLND were...
