“…Thus, the total number of patients in the present study was comparable to that reported by the Japanese clinical statistics 2001 registry. With respect to histopathological tumour type, adenoid cystic carcinoma was commonest, followed by mucoepidermoid carcinoma, which is consistent with the results of Endo et al 1 The prevalence of each tumour type should be examined using data from many more studies, given the limited number of patients included in any one study.…”

“…1,5,7 In the present study, the survival rate of patients with stage IV cancer was poor, and a statistically significant difference was observed compared with the survival rates of patients with stage I, II or III tumours. Few previous studies have compared patient survival results for different histopathological tumour types; however, some survival results have been reported for adenoid cystic carcinoma and mucoepidermoid carcinoma ( for which patient numbers are greater).…”

“…Goldblatt and Ellis 5 reported that 50 of 55 patients with minor salivary gland tumours of the tongue had malignant disease, and that tumour progression, age and tumour grade were prognostic factors. Endo et al 1 reported the prevalence of different minor salivary gland tumour types; adenoid cystic carcinomas were commonest, followed by mucoepidermoid carcinomas. According to the Japanese clinical statistics 2001 registry, 6 minor salivary gland carcinoma accounted for four of 162 cases of oropharyngeal cancer (2 per cent), and 15 of 478 cases of cancer of the oral cavity (3 per cent) (based on data from 29 sites).…”

“…Minor salivary gland carcinoma of the oral cavity or oropharynx is rarely encountered in the clinical setting; the prevalence is reported as approximately only 1 to 2 per cent of malignant head and neck tumours 1 , 2 . This study analysed the prevalence of these lesions and reviewed their treatment, based on histopathological findings in patients treated at our centre.…”

This paper reviews 22 cases of minor salivary gland carcinoma of the oral cavity or oropharynx which were treated at Kurume University Hospital between 1976 and 2005. Minor salivary gland carcinoma was observed in eight of 362 patients with cancer of the oral cavity (2 per cent), and in 14 of 275 patients with cancer of the oropharynx (5 per cent). The five-year and 10-year survival rates of patients with oropharyngeal minor salivary gland carcinoma were 90 per cent. No statistically significant difference was observed between survival rates for oropharyngeal minor salivary gland carcinoma and for oropharyngeal squamous cell carcinoma (p = 0.06). The five- and 10-year survival rates of patients with oral cavity minor salivary gland carcinoma were 75 and 37 per cent, respectively. No statistically significant difference was observed between survival rates for oral cavity minor salivary gland carcinoma and oral cavity squamous cell carcinoma.Patients' survival results correlated well with the clinical stage of their lesions. A significant difference in survival was observed, comparing stage IV with stages I, II and III (p = 0.04). In contrast, no significant relationship was found between either survival and tumour type or survival and treatment. Adjuvant therapy is recommended for patients with grade III adenoid cystic carcinoma with perineural infiltration or intravascular infiltration.
