Treatment of genitourinary rhabdomyosarcoma in children
Insights
Combined therapy including surgery, radiotherapy, and chemotherapy offers hope for children with genitourinary rhabdomyosarcoma. Many survivors retain a functional bladder, highlighting the effectiveness of tailored treatment approaches.
Area of Science:
- Pediatric Oncology
- Surgical Oncology
- Radiation Oncology
Background:
- Rhabdomyosarcoma is a rare childhood cancer affecting pelvic organs.
- Treatment for genitourinary rhabdomyosarcoma requires a multidisciplinary approach.
Purpose of the Study:
- To evaluate the outcomes of combined modality therapy for genitourinary rhabdomyosarcoma in children.
- To assess the impact of different treatment sequences on survival and bladder function.
Main Methods:
- Retrospective analysis of 27 children with bladder, prostate, uterus, cervix, or vaginal rhabdomyosarcoma.
- Treatment included surgery, radiotherapy, and multi-drug chemotherapy in various combinations and sequences.
Main Results:
- 18 of 27 patients (67%) survived with a median follow-up of 86 months.
- 9 patients (33%) retained a functional bladder.
- Extirpative surgery followed by adjuvant chemotherapy was highly effective for local control and survival.
Conclusions:
- Combined modality treatment, particularly with initial surgery, improves survival rates for pediatric genitourinary rhabdomyosarcoma.
- Preservation of bladder function is achievable in a significant proportion of patients.
- Multidisciplinary management is crucial for optimizing outcomes in these rare pediatric cancers.
Abstract:
We report on 27 children with rhabdomyosarcoma of the bladder, prostate, uterus, cervix and vagina treated with combined therapy of surgery, radiotherapy and multiple drug chemotherapy. Of the 27 patients 18 are alive for 13 to 147 months (median 86 months) and 9 have retained a functional bladder. Extirpative surgery followed by adjuvant chemotherapy and occasionally radiation therapy was most effective for local tumor control and 7 of 10 patients survived, including 5 with an intact functional bladder. Primary use of chemotherapy in 13 patients with extensive disease resulted in complete tumor control in only 3 but 7 survived, including 4 with an intact bladder. Radiation therapy used concomitantly with chemotherapy failed to control the local tumor but with subsequent extirpative surgery all 4 patients survived.
