This clinico-pathologic study of primary oral leiomyosarcomas and analysis of potential prognostic factors involved a literature review of 64 cases and a report of four cases treated in the authors’ unit. The demographic details, clinical presentation, diagnosis, treatment and outcome were documented for the whole group and clinico-pathologic variables analysed to detect potential prognostic factors. The most common presentation was that of a painless mass, with peak incidence in the 6th decade and a slight male predeliction (M:F = 1.3:1). The maxilla was the most frequently involved site, followed by the mandible and tongue. Surgical excision was most commonly employed with radiotherapy and chemotherapy being reserved for recurrent and metastatic tumours. Local recurrence (34%) and metastasis (35%) were not uncommon and occurred most frequently to the lungs and regional lymph nodes (15%). Age, sex, size and mitotic index were not statistically related to recurrence or metastasis. Site (P = 0.0125) was a predictor of metastasis. Metastasis (P = 0.010) and lesions involving the maxilla and mandible (P = 0.019) were associated with decreased survival. The estimated 5 year survival was 55% for the whole group and 43% and 19% for patients with bony involvement and metastasis respectively.
