Kaberi Kakati, Tashnin Rahman, Nizara Baishya

Abstract :

Introduction : Adenoid cystic carcinoma constitutes around 1% of all head and neck malignancies. Although commonly found in salivary glands, it can occur at other sites in head and neck region like nose and paranasal sinus, larynx, oropharynx. Here, we sought to present our experience with adenoid cystic carcinoma of head and neck region. Methods and Materials : A retrospective analysis was conducted from 2011–2015 on adenoid cystic carcinoma cases in head and neck region from a prospectively maintained Institutional database. Only the cases who took treatment at our Institute were taken for analysis. The cases were analysed on the basis of demographic profile, tumor site, stage, treatment modalities and survival outcome. Results : A total of 30 cases were included in this study. 46.7% cases were from salivary gland, followed by maxilla. 80% presented in T3 and T4 stage. 13.3% had distant metastases at presentation. Recurrence rate was 22.7%. 5 years Overall Survival (OS) and 5 years Disease Free survival (DFS) were 45.3% and 71.7% respectively. Conclusion : The clinical behaviour of this tumor and its propensity for recurrence makes it necessary for a long term periodic follow up. Advanced stage of the disease calls for morbid treatment and impacts survival functions.
