Insights
This study reviewed 30 pediatric bladder tumors over 10 years, finding a mix of inflammatory and malignant types. Fortunately, most patients achieved no evidence of disease after treatment, highlighting the importance of understanding pediatric bladder tumor management.
Area of Science:
- Pediatric Urology
- Oncology
- Medical Research
Background:
- Pediatric bladder tumors are rare, with limited existing data on their presentation, management, and natural history.
- Understanding the spectrum of these tumors is crucial for effective clinical care.
Purpose of the Study:
- To present a single pediatric urology practice's 10-year experience with bladder tumors in children.
- To expand knowledge on the presentations, management strategies, and natural history of pediatric bladder tumors.
Main Methods:
- Retrospective review of electronic medical records from 2011 to 2021.
- Inclusion criteria focused on bladder tumors, excluding patients with pre-existing bladder conditions.
- Utilized International Classification of Diseases, Tenth Revision (ICD-10) and Current Procedural Terminology (CPT) codes for patient identification.
Main Results:
- Thirty pediatric bladder tumors were identified in patients aged 16 months to 19 years.
- Tumor types included inflammatory subtypes (11), papillomas (4), rhabdomyosarcomas (4), papillary urothelial neoplasms of low malignant potential (3), and others (8).
- All 30 patients achieved no evidence of disease at the most recent follow-up, with a median follow-up of 19 months.
Conclusions:
- Pediatric bladder tumors encompass a range from aggressive rhabdomyosarcomas to more common benign urothelial lesions.
- The majority of identified tumors were of less aggressive subtypes.
- Knowledge of treatment options and natural history benefits clinicians and parents.
Objective:
To present our experience in a single pediatric urology practice over a 10-year period with bladder tumors in the pediatric population in an effort to add to the relatively small amount of existing data. We hope to expand the community's knowledge of presentations, management and natural history of pediatric bladder tumors.
Methods:
We retrospectively queried our electronic medical records for International Classification of Diseases, Tenth Revision (ICD-10) and Current Procedural Terminology (CPT) codes relevant for bladder tumors. Patients with underlying bladder pathology, such as neurogenic bladder, history of bladder exstrophy, and history of bladder augmentation, were excluded.
Results:
We identified 30 patients with bladder tumors from 2011 to 2021. There were 21 males and 9 females. Age at diagnosis ranged from 16 months to 19 years. Tumors identified were: 11 of various inflammatory subtypes; 4 papillomas; 4 rhabdomyosarcomas; 3 papillary urothelial neoplasms of low malignant potential and 8 of other types. Treatment included transurethral resection of bladder tumor, chemoradiation and laparoscopic partial cystectomy. Twenty nine patients had disease limited to the bladder and 1 had disease outside the bladder. Follow-up ranged from 2 weeks to 13 years (median 19 months). All patients had no evidence of disease at most recent follow-up.
Conclusion:
Pediatric bladder tumors range from aggressive rhabdomyosarcomas to more benign urothelial lesions. Fortunately, the latter type of tumor is the more prevalent lesion. Knowledge of the treatment options and natural history of these tumors will hopefully be of benefit to clinicians and parents alike.
