; Ademar Lopes, TCBC-SP 6 RESUMO: Objetivos: Os sarcomas sinoviais são tumores raros e agressivos que acometem adultos jovens, com sobrevida doença-específica em cinco anos de 57 a 63%. O presente estudo analisa a experiência institucional com este tumor, dando ênfase à associação entre variáveis clínicas, padrões de recorrência e sobrevida. Método: Entre 1970 e 2001 foram identificados 57 pacientes com sarcomas sinoviais. Fatores demográficos, clínicos e anatomopatológicos foram pesquisados. Associações entre variáveis clínicas e a sobrevida livre de recidiva local, livre de metástases e doença-específica em cinco anos foram calculadas. Resultados: A idade mediana dos pacientes foi 26 anos, 56% eram masculinos, 79% eram brancos. Localizavam-se em membro inferior em 74%, proximalmente em 53%. O sintoma mais comum foi a presença de tumor em 42%. Na admissão 18% eram intactos, 42% manipulados e 40% recidivados. A maioria era maior que 5 cm., e três pacientes apresentavam metástase linfonodal. A cirurgia mais freqüente foi ressecção ampla, 30% necessitou amputação. Margens amplas foram obtidas em 65%, 51% eram tumores bifásicos. Neoadjuvância foi utilizada em 46% e adjuvância em 58% dos casos. As sobrevidas livre de recidiva local , metástases e doença específica em cinco anos foram 60±8%, 47±7% e 58±7%. A localização proximal do tumor associou-se com preservação de membro (p=-0,001), margens inadequadas (p=0,006) e subtipo bifásico (p=0,047). Conclusões: Os dados confirmam a hipótese de tratar-se de tumor agressivo, com altos índices de recidiva local e à distância. Os resultados do tratamento são comparáveis a outros centros especializados. Tratamento fora destes centros deve ser desencorajado (Rev. Col. Bras. Cir. 2005; 32(6): 304-309).
Objectives: Anterior flap hemipelvectomy is an unusual procedure used to treat tumors from the buttock and proximal posterior thigh. This study reviews the technique and analyzes 8 such operations.Methods: Charts from 1973 to 2001 were reviewed. The technique is described and demographics, histology, symptomatology, tumor status, blood transfusion, operative time, ICU time, use of neo-or adjuvant therapy, complications, patterns of recurrence and outcome were recorded.Results: The ratio male:female was 6:2. Seven patients were Caucasian, one was Asian. Median age was 47.5 years. Pain and swelling were the major complaints. Two patients had previous manipulation before referral. Most tumors were sarcomas. All patients had regional disease at diagnosis. All procedures had curative intent. Median operative time was 427 minutes. Median blood transfusion was 1200 mL. Maximum ICU permanence was 48 hours. Six patients received neo-or adjuvant therapy. The most frequent complication was phantom pain. Recurrences were local in 1 case and pulmonary in 4 cases. Median follow up was 10.5 months. Median survival was 21 months. There was no operative mortality.Conclusions: The anterior flap hemipelvectomy is a safe and effective procedure to treat gluteal or high posterior thigh tumors. It has a low rate of complications, and should be the reconstructive procedure of choice in such cases.
