Abstract

The aim of this study was to determine predictors of outcome in childhood truncal rhabdomyosarcoma.Retrospective chart review evaluating the impact of demographic features, disease characteristics, and the extent and timing of surgical intervention on outcome was performed.Thirty-three patients with a median age of 8 years were identified. Most had advanced Intergroup Rhabdomyosarcoma Study group III (n = 13) or group IV (n = 9) disease. Primary site included 20 (61%) chest wall, 6 (21%) paraspinal, 5 (15%) periscapular, and 1 (3%) abdominal wall. Most tumors were embryonal (n = 21), larger than 5 cm (n = 27), and locally invasive (n = 13); 7 had positive nodes. Tumor size, nodal status, and gross total tumor resection (upfront or delayed) were significant predictors of event-free and overall survival. Tumors 5 cm or smaller were amenable to upfront surgical resection (P = .007). In patients with tumors larger than 5 cm, resection at any time was associated with a 10-year overall survival 57% +/- 13% compared with 8% +/- 5% in those who had no surgery (P = .003). Tumor recurrence was local in 44% of cases, and survival after local recurrence was rare (1 of 8).Tumor size, nodal status, and gross total resection at any time are significant predictors of outcome in truncal rhabdomyosarcoma. Gross tumor excision should be the goal of surgical intervention in this disease.
