Re-excision after unplanned resection of nonmetastatic nonrhabdomyosarcoma soft tissue sarcoma in children: Comparison with planned excision

Abstract

BackgroundIt is not exceptional to come by children with initial unplanned surgical intervention for nonrhabdomyosarcoma soft tissue sarcomas (NRSTS). The aim of this study was to evaluate the presence of residual disease in these patients after re-excision and compare the treatment outcomes with patients who had planned upfront excision. MethodsThe data of patients with primary nonmetastatic NRSTS with initially unplanned excision who underwent re-excision between March 2006 and December 2014 were analyzed and the results compared with patients having planned upfront excision in the similar period. ResultsOf the 84 patients, 40 (48%) had an unplanned excision elsewhere; 35 of these patients had a re-excision. Twenty-one of the remaining 44 patients underwent upfront planned excision. A residual tumor was present in 16 (45.7%) patients. There was no significant difference in the local recurrence, distant metastases, or deaths in patients with re-excision or planned excision. The 5-year overall, disease-free survival and local control rates were, respectively, 93.5%, 90.2% and 96.6% for the re-excision group and 84.9%, 65.2% and 88.5% in the planned excision group (p=NS). ConclusionsThe probability of residual disease following unplanned excision of NRSTS is high. The outcomes following re-excision are similar to that with planned excision.
