BackgroundThe upper aerodigestive tract (UAT) includes the nose and paranasal sinuses, oral cavity, pharynx, larynx, and salivary glands. Cancers of the UAT constitute approximately 4% of all malignancies. In this study, the varied nature of the UAT cancers was studied to find out their incidence, etiology, and clinicopathological correlations.Materials And MethodsThis prospective, observational, and clinicopathological study was conducted on 100 patients who were presented at outdoor in the Department of ENT, Government Medical College/Rajindra Hospital, Patiala, Punjab, India, from October 2016 to October 2018. Proven cases of UAT cancers were taken up and reviewed to gather data on multiple clinicopathological variables, such as age, sex, predisposing factors, and site of pathology. Histopathological differentiation was noted after conducting a biopsy.ResultsMost patients of UAT cancers were in the age group of 40-70 years. Maximum incidence was among males (82%) compared to females (28%). The most common predisposing factor was alcohol + smoking (28%), followed by alcohol + chewing tobacco (25%). The most common symptom in the oral cavity was ulcer and odynophagia (38%) each. In oropharyngeal cancers, dysphagia (92%) was the most common symptom. In laryngeal cancers, dyspnea (68%) and hoarseness of voice (32%) were the most common. The most common site involved in UAT cancers was the oral cavity (31%), followed by oropharynx (28%), larynx (22%), hypopharynx (7%), and salivary gland (5%). The most common histopathological type was squamous cell carcinoma (SCC) (90%). Most of the ulceroproliferative and exophytic growth was moderately differentiated SCC on histopathology.ConclusionStudies are essential for education and awareness aimed at reducing exposure to habit-forming substances.
