Context: Nasopharyngeal cancers were initially thought to be an uncommon disease in Nigeria, but recent studies have shown a steady increase in the incidence of the disease with an associated increase in morbidity and mortality due to late presentation. Aims: The aims are to evaluate the mode of presentation and referral pattern of nasopharyngeal cancer patients seen. Settings and Design: This was a retrospective review of patients with nasopharyngeal cancer seen in the department of Radiation Oncology U.C.H. Ibadan from 2000 to 2009. Methods and Material: Patients' biodata, clinical-pathologic presentation, and site of referral were retrieved using data extraction form and subsequently analyzed using Microsoft Excel (2013). Statistical Analysis Used: It is a descriptive analysis. Results: A total of 205 patients with histologically confirmed nasopharyngeal cancer seen during the study period were analyzed. The mean age of the patients was 41.7 years with 144 (70.2%) males and 61 (29.8%) females. The commonest presenting complaint was cervical lymphadenopathy in 98.5% of patients followed by nasal blockade, nasal discharge, and epistaxis with 82.0%, 78.0%, and 51.2%, respectively. Undifferentiated carcinoma was the commonest histologic type (68.8%). Majority of patients were civil servants (33.2%). The habit of smoking and alcohol ingestion was unspecified in majority of patients (43.4%). Ingestion of smoked fish has been found in majority of patients (122, 59.5%) with the disease in this study. Most of the patients came from southern part of the country which coincides with the geographic distribution of Burkitt's lymphoma; hence, the possibility of Epstein-Barr virus as one of the likely causative agents. None of the patients presented with stage I disease, while most patients presented at stage III 129 (62.9%). Conclusions: Nasopharyngeal cancer is common. Cervical lymphadenopathy, nasal blockade with undifferentiated histology, and late presentation were the norm. Referrals were from all the regions of the country.
