A retrospective study of six patients with mandibular metastatic carcinoma.
Mandibular metastatic carcinoma is a rare lesion that accounts for <1% of all oral malignancies. To provide greater experience in this field, the present study was conducted in which 6 cases of mandibular metastatic carcinoma were retrospectively reviewed. The origin of the lesions was the prostate in 2 cases, the lungs in 2 cases, the breast in 1 case and the thyroid gland in 1 case. The clinical and computed tomography features, surgical management and follow-up outcomes were investigated. The study indicated that surgeons should include the suspicion of metastasis in the differential diagnosis for mandibular tumor, particularly in patients who have a history of malignancy. A poor prognosis was associated with the examined patients. To extend the survival time as long as possible, a treatment strategy using multiple therapies, including segmental mandibulectomy, radiotherapy and chemotherapy, is recommended.
