TREATMENT Chemotherapy Started In DEC.2019 According to EURO.EWING 99 protocols including 6 cycles of VIDE and 8 cycles of VAI. Surgery was done after initial 6 cycles and re-evaluation by orthopedic department in CHF where wide marginal resection and bone excision was done. Limb was saved . Treatment completed in Nov.2020 now Patient is completely well.
