Abstract:
Objective: To determine the prognostic factors of primary osteosarcoma in adults . Methods:This is a review of 54 patients older than 40 years (24 men and 30 women) who were treated between 1998 and 2011 at the authors ’ institution .Demographic information and follow-up data were obtained and statistically analyzed .Results: Tumors involved the limbs in 30 patients ( 55 .5%) and axial skeleton in 17 patients (31.5%), and arose from soft tissue in 7 patients (13%).And 6 patients (11.1%) had synchronous metastasis .According to our review , tumors were treated surgically in 52 patients (96.3%).Local recurrence was documented in 14 patients (26.9%).Metastasis after diagno-sis appeared in 21 patients (38.9%).In the 52 patients who received the surgical treatment , the 5 year disease-free survival and overall survival rates were 43.7% and 50.4%, respectively.Conclusion:Adult patients with primary osteosarcoma had a poor clinical outcome .Inadequate surgical margins , more tumors in the axial location due to high recurrence rates , metastatic disease at presentation , and large tumor volumes were associated with significantly lower survival rates .Aggressive multi-agent treatment regimens might improve survival .
