Abstract

Objective: To identify the recurrence after surgery in patients diagnosed with salivary gland tumor. Methods: Data on age, gender, type of salivary gland tumor, local recurrence, stage, primary site and type of treatment were collected at Hospital de Câncer de Pernambuco, Recife, Brazil, using a standard form based on clinical records. These were described and analyzed with a significance level of 5% (p < 0.05). Results: Of the 55 medical records that comprised the study sample, 51% were male. Overall mean age was 55 years, ranging from 13 to 90 years. Adenocarcinoma (NOS) was the most prevalent (n = 17), followed by adenoid cystic carcinoma (ACC) (n = 14; 25.5%). Among all sites, parotid gland (n = 29; 53%) was the most common. Among the patients studied, 61.8% (n = 34) had no distant metastasis, but 38.18% (n = 21) did, and 14.55% (n = 8) showed bone metastasis. Conversely, 34.55% (n = 19) of the patients had recurrence only one year after diagnosis. The neoplasm with the highest recurrence rate was NOS (n = 17, 30.91%), followed by CAC (n = 14, 25.45%). Conclusion: Results show a prevalence of male patients and parotid gland involvement, with NOS adenocarcinoma and CAC being the most frequent neoplasms. Distant metastasis occurred in 38.18% (n = 21) of the cases, and bone was the most affected site. Surgery with adjuvant radiotherapy (n = 15) was the treatment of choice.
