Tratamento do Sarcoma Sinovial em Pacientes com Menos de 18 Anos
O sarcoma sinovial em pacientes pediátricos apresenta considerações de manejo específicas. Esta página resume a abordagem de primeira linha para pacientes com menos de 18 anos de idade, onde evidências de estudos prospectivos dedicados e análises conjuntas de grupos cooperativos ajudaram a definir um quadro terapêutico ideal.
Cenário Clínico
O sarcoma sinovial pediátrico (idade <18 anos) é raro, tornando inerentemente difícil a realização de grandes ensaios randomizados nessa população específica. Apesar disso, a abordagem terapêutica ideal para esses pacientes está agora mais bem definida, baseando-se em estudos prospectivos pediátricos e de adolescentes e em análises conjuntas com grupos cooperativos de adultos.

- The optimal approach to the treatment of SS in pediatric patients is now better defined.
- The disease is rare in the pediatric population, making it difficult to conduct randomized pediatric SS-specific clinical trials.
- In localized SS, this typically involves initial first-line resection, where feasible, plus adjuvant or second-line treatments, including a combination of full-dose doxorubicin and ifosfamide chemotherapy, depending on an individual risk stratification that takes account of tumor stage, site, and size.
- A prospective trial by the EpSSG in patients <21 years of age with nonmetastatic SS showed that with multimodal treatment, which included radiotherapy and a combination of doxorubicin and ifosfamide chemotherapy according to tumor stage, site, and size, 5-year EFS was 80.7% and OS was 90.7%.
- A joint analysis by the EpSSG and the Children's Oncology Group (COG), however, found that pediatric patients with a localized nonmetastatic SS tumor of grade 2 of any size or grades 3 and 5 cm that had been fully resected could be treated effectively with surgery alone.
