- Abstract
Background: The aim was to investigate the value of adjuvant radiotherapy for locally advanced soft tissue sarcoma after hyperthermic isolated limb perfusion (ILP) with tumor necrosis factor alpha and melphalan followed by limb-saving surgery., Methods: From 1991 to 2003, 73 patients (median age, 54 years; range, 14-80 years) underwent 77 ILPs, followed by resection in 68 patients (93%). Radiotherapy was administered in case of marginally or microscopically positive resection margins. Local recurrences were scored and calculated according to the Kaplan-Meier method and log-rank test., Results: After residual tumor mass resection, 58% received radiotherapy (external beam radiotherapy [EBRT]+ group), and 42% did not (EBRT- group). The median follow-up was 28 months (range, 2-159 months). A significantly better local control rate was observed in the EBRT+ compared with the EBRT- group (P<.0001). When only R0 resections in patients without metastasis were considered, the significance remained between groups (P=.0003). In the EBRT- group, an R1 or R2 resection resulted in earlier relapse of local disease compared with R0 resections (P=.0475)., Conclusions: Adjuvant EBRT reduces the risk for local recurrence after delayed resection in soft tissue sarcoma patients treated with ILP and tumor necrosis factor and is indicated when resection margins are close or microscopically positive. It also seems beneficial after an R0 resection.
