Answer

NCCN recommendations for treatment of chondrosarcoma are as follows [1] :

  • Enrollment in a clinical trial should be considered when available; in addition, whenever possible patients should be referred to a tertiary care center with expertise in sarcoma, for treatment by a multidisciplinary team

  • Wide excision or intralesional excision with or without adjuvant therapy for resectable low-grade and intracompartmental lesions

  • Wide excision is preferred for pelvic low-grade tumors

  • High-grade (grade II, III), clear cell, or extracompartmental lesions, if resectable, should be treated with wide excision

  • Wide excision should provide negative surgical margins and may be achieved by either limb-sparing surgery or amputation

  • Postoperative treatment with proton and/or photon beam radiation for tumors in unfavorable location

  • Consider radiation therapy for unresectable tumors

  • No established chemotherapy regimens exist for grade I-III tumors; treatment of patients with dedifferentiated chondrosarcoma should follow osteosarcoma guidelines; treatment of patients with mesenchymal tumor should follow Ewing sarcoma guidelines; dasatinib is an option

ESMO-PaedCan-EURACAN guidelines recommend that low-grade central chondrosarcomas in the long bones of the limbs be managed by curettage, with or without adjuvant therapy (eg, phenol, cement, cryotherapy) and low-grade peripheral chondrosarcomas be surgically excised. Higher-grade chondrosarcomas and all chondrosarcomas of the pelvis or axial skeleton should be surgically excised with wide margins. For dedifferentiated chondrosarcoma, if wide margins cannot be achieved with limb salvage, consideration of amputation is recommended. [2]

The ESMO-PaedCan-EURACAN guidelines are in agreement with NCCN regarding chemotherapy regimens for mesenchymal chondrosarcoma, and also note the following [2] :

  • Dedifferentiated chondrosarcoma is often treated as a high-grade bone sarcoma, with systemic and local therapies that need to be adapted to patient’s age.
  • Skull base chondrosarcomas can be treated with high-dose radiation therapy, including proton or carbon ion beam radiation therapy.
  • Doxorubicin and ifosfamide may prove active in chondrosarcoma, especially in high-grade lesions, and gemcitabine in combination with docetaxel has also been reported to be effective.

NCCN recommendations for treatment of local recurrence of chondrosarcoma are as follows [1] :

  • Wide excision if resectable

  • Consider radiation therapy or re-resection to achieve negative surgical margins following wide excision with positive margins

  • Radiation therapy for unresectable recurrences

  • Surgical excision, cyclophosphamide and sirolimus, or participation in a clinical trial for patients with systemic recurrence of a high-grade chondrosarcoma
