Survival will depend on achieving complete control over the primary neoplasm so that spreading into neighboring tissues and occurrences of metastatic foci are avoided. In this regard, the first surgical intervention should have the main aim of performing resection that is wide enough to prevent local recurrence. For this to be achieved, surgical margins of 4 cm on all sides are necessary, thereby leading to cure for almost all patients and resulting in 10-year survival of 97%. With this being in the calcaneus a below the knee amputation is the best procedure for survival.
