Maxillo-facial osteosarcoma is a rare primary tumor in adults. Between 1980 and 1990, 11 patients were considered; 6 had primary tumors in mandible and 5 in the maxillo-paranasal region. All cases were treated with surgery as the primary modality. Resection was radical in 8 patients and palliative in the other 3. Adjuvant postoperative chemotherapy with adriamycin was administered for 6 months in the 8 patients treated with complete resection. After a median follow-up of 3 years, 7 patients are still alive and 4 died of progressive disease. In the group of patients treated with radical surgery and adjuvant chemotherapy only one died for distant metastases, and 7 are living free of disease. With complete surgical resection long term local tumor control was achieved in all patients. No patient treated with incomplete resection achieved local tumor control with subsequent radiotherapy. The possibility of performing a complete surgical resection of the primary appears to be an essential step to obtain long term local control and survival in maxillo-facial osteosarcoma. Our series is, however, too limited to evaluate the therapeutic benefit of adjuvant chemotherapy.

Osteosarcoma (OS) is a rare primary malignant bone tumor in adolescents and children with a poor prognosis. The identification of prognostic genes lags far behind advancements in treatment. In this study, we identified differential genes using mRNA microarray analysis of five paired OS tissues.

Osteosarcoma is the most common malignant bone tumor, tending to be aggressive and recurrent. The therapeutic development for treating osteosarcoma has been largely hampered by the lack of effective and specific targets. Using kinome-wide CRISPR-Cas9 knockout screens, we systematically revealed a cohort of kinases essential for the survival and growth of human osteosarcoma cells, in which Polo-like kinase 1 (PLK1) appeared as a specific prominent hit.

Purpose Of Review: This article presents a review of the literature on mandibular osteosarcoma, focusing on the main aspects of its management, including diagnosis, histotype, and treatment. The literature published in the last 5 years was considered but because of the rarity of mandibular osteosarcoma, major publications from the past have also been included.
Recent Findings: Management of mandibular osteosarcoma still lacks a clear standard of care, and treatment has not changed markedly over the past several years.
