Prevalence of Oral and Pharyngeal Cancers and the Relationship Between Tumour Size and Lymph Node Metastases in Oral Cancer.

Abstract

\n Background: the study aimed at studying the incidence and prevalence rates of oral and pharyngeal cancer and their distribution according to gender, tumour size, histological type and chief complaint. We also tackled the relationship between the tumour size and the metastasis to the regional lymph nodes.Materials and Methods: This cohort retrospective study was done in Al-Mouasat hospital from January 2017 to June 2020. The population included patients with oral or pharynx cancer who were admitted to the Ear, Nose, Throat department.Results: The total participants were 96 cases. The median age was 57 year. The most common tumour location was oral tumour 58.3%, and the most common chief complaint about oral tumour was mass by 62.5%. while nasopharynx cases most commonly came with neck mass 68.2%. 50% was the percentage of dysphagia that was the most common complaint. Squamous cell carcinoma (SCC) was the most common histologic type < 90% of the oral, oropharynx, and hypopharynx cases. About the classification of the tumour due to its subsite 33.9% of the oral cases were in lip and especially the lower one. Whereas, oropharynx most frequent tumour site was the tonsil (50%). we found statistical evidence for the relationship between the tumour size (T) and the metastasis to the regional lymph node (N) in oral cancer.Conclusion: Oral and pharyngeal cancer is a very important issue. And according to our paper, the most frequent cancer was oral cancer and especially lower lip tumour. oral cancer presents with mass. whereas, the nasopharyngeal cancer presentation was neck mas. The most common histological type was SCC. And we reached a relationship between the T and N in oral cancer
