Evaluation of local recurrenc of osteosarcoma after surgery in extremities (A retrospective study)

Local recurrence of osteosarcomas usually seen together with displant metastasis which provides a very poor prognosis for the disease. We evaluated the important factors in local recurrence of osteosarcomas in 34 patients. We excluded those tumors in central skeleton and pelvic bones for the reason that wide resection of those tumors is almost impossible and the rate of recurrence is high. We evaluated the impact of age, sex, location of tumor, neoadjuvant and adjuvant chemotherapy, tumor degree, kind of surgery and margin of surgery on the recurrence of limb osteosarcoma. We concluded that except for the response to neoadjuvant chemotherapy and attaining a good margin of surgery, other factors mentioned above do not have any impact on recurrence of osteosarcoma after surgery in extremities.
