[Rhabdomyosarcoma of the bladder in a child: report of a case]
Insights
This case study details an 11-month-old boy with bladder rhabdomyosarcoma. Combination chemotherapy with vincristine, bleomycin, and cis-DDP showed initial effectiveness but the tumor relapsed, leading to fatal pulmonary metastases.
Area of Science:
- Pediatric Oncology
- Urological Pathology
Background:
- Rhabdomyosarcoma of the urinary bladder is a rare and aggressive malignancy in infants.
- Early diagnosis and effective treatment are crucial for improving outcomes in pediatric bladder cancer.
Observation:
- An 11-month-old boy presented with complete urinary retention due to embryonal rhabdomyosarcoma of the bladder.
- Initial treatment with vincristine, actinomycin-D, and radiation therapy was ineffective.
- Subsequent chemotherapy with vincristine, bleomycin, and cis-diamminedichloroplatinum (cis-DDP) resulted in a non-palpable tumor.
Findings:
- Despite initial response, the tumor relapsed one year later, progressing to diffuse pulmonary metastases.
- The patient ultimately succumbed to respiratory failure secondary to metastatic disease.
Implications:
- This case highlights the challenges in treating recurrent bladder rhabdomyosarcoma in young children.
- Combination chemotherapy including vincristine, bleomycin, and cis-DDP may offer a therapeutic option for recurrent disease, though long-term efficacy remains a concern.
- Further research into novel therapeutic strategies is warranted for improving prognosis in pediatric bladder rhabdomyosarcoma.
Abstract:
A case of rhabdomyosarcoma of the urinary bladder in an 11-month-old boy is presented. The chief complaint was complete urinary retention and histological examination showed embryonal rhabdomyosarcoma of the bladder. Initially, he was treated with vincristine, actinomycin-D and radiation therapy. This therapy was not effective, and he was next treated with vincristine, bleomycin, and cis-DDP. This therapy was significantly effective, and the tumor became non-palpable on physical examination. After six courses he was discharged and maintenance chemotherapy was continued until the tumor relapsed 1 year later. Finally he died of dyspnea due to diffuse pulmonary metastases approximately 2 years after the first diagnosis. We herein discuss several points which affect the prognosis and the usefulness of chemotherapy, especially combination therapy with vincristine, bleomycin, and cis-DDP for recurrent cases.
