Which adjuvant treatment(s) would you recommend for an incompletely resected, high grade osteoblastic osteosarcoma of the jaw?  

Since the patient has already had partial local control treatment, may make sense to complete local control therapy first even though this is not the norm in osteosarcoma.Thus, re-evaluate by an experienced ENT oncologic surgeon for re-resection. Adjuvant RT thereafter. Even if complete resecti...

I ask for adjuvant radiation after surgery and chemotherapy. Literature on osteoblastic osteosarcoma says curative treatment should be chemotherapy and resection, with radiation instead of resection reserved for unresectable tumors (e.g. sacral tumors).  The literature is mostly long bone tumo...

As this is a rare condition, the patient should be evaluated at a multidisciplinary sarcoma center.

Complete resection if at all possible could potentially be curative....
