Urothelial cancer is a rare pediatric malignancy; previous analyses suggest lower rates of recurrence and death as compared to adults. We analyzed pediatric bladder cancer information in a national database, hypothesizing that survival would be better in children than adults.
We analyzed the 2004-2016 National Cancer Database (NCDB) for children and adolescents (0-18 years) with urothelial bladder cancer. Rhabdomyosarcoma patients were excluded. Assessed variables included TNM staging, pathology, tumor size, surgical procedures, and post-operative re-admissions. Overall survival was defined as months since diagnosis as of last follow-up.
Of 140 urothelial tumors reported to NCDB between 2004-2016, 75.7% (N=106) were stage 0 at diagnosis, 6.4% (N=9) were stage I, 2.9% (N=4) were stage II and 3.6% (N=5) were stage IV, while 11.4% cases (N=16) were unknown. From available mortality data (121 patients), no patients died after definitive surgical resection. Only 1 mortality was reported at 90 days, although cause of death was reportedly unknown. Three (2.5%) patients were lost to follow-up, and most (96.7%) were alive at 90 days.
Short-term survival outcomes among children and adolescents with urothelial bladder tumors captured in NCDB are reassuring. Future investigations focused on long-term outcomes and appropriate surveillance in this rare patient cohort are imperative to better guide management options.
