Osteosarcoma de maxilar y mandíbulaconsideraciones epidemiológicas, clínicas y evolutivas

Resum

Foundation: to assess the epidemiological, clinical and evolutionary aspects of the maxillary and mandibular osteosarcoma. Material and method: the study consists of a meta-analytics review of the literature about 396 patients who suffered from maxillary and mandibular osteosarcoma since 1984 until 2010. Results: the most common osteosarcoma is the mandibular type, especially the one which affects to men (57.9 %) between the second and third period of their lives. The prevailing histological tumor is the chondroblastic kind (48 %), particularly the high rank (III and IV type). The frequent clinical manifestations are inflammation, pain, the widening of the periodontal ligament, bone expansion and the extension to the soft tissues. The most used treatment was the complete surgical removal (47.8 %) or the combination with chemotherapy (22.8 %) either radiotherapy (19.1 %). The local relapse appeared again in 19% of the patients and metastasis in the 15.4 %. Conclusions: the most frequent osteosarcoma is the mandibular one, which affects to men between the second and third period of their life, and the surgical removal is the best way of treatment.
