Factors Associated with Late Diagnosis of Oral Cancer

Abstract

Objective: The aim of the present study was to determine associations between the late diagnosis of oral cancer and demographic/clinical factors. A quantitative cross-sectional study was carried out in 2007. Material and Method: Oral tumors were recorded based on the TNM staging system, with T1 and T2 considered early diagnosis and T3 and T4 considered late diagnosis. Results: Patient age ranged from 30 to 105 years (mean: 64.7). Just over half of the patients (54.9%) resided in urban areas and approximately 1/4 (25.7%) had an agricultural occupation. The majority had smoking habits (89.9%) and consumed alcohol (62.5%). The most frequent tumor site was the tongue (42.4%), followed by the hard palate (19.2%) and lip (12.2%). The majority (70.1%) were in advanced stages (III and IV). A greater percentage of smokers were in advanced stages than non-smokers. The percentage of cases in the early stages was lowest when the tumor was located in the tongue (14.1%) and highest when located in the buccal mucosa (80.0%). Conclusion: The main causes of the late diagnosis of oral cancer are insufficient training on the part of physicians and dentists in the field of pathology, delays on the part of patients in seeking medical assistance and deficient access to quality medical care, reflecting the absence of preventive public health programs and an effective healthcare system.

Assessment of factors associated with early and late stage diagnosis of buccal mucosa carcinoma

“…Similarly, many studies also reported that 50% of cases of oral cancer were diagnosed with advanced condition of stage III and IV which had higher morbidity and mortality rates (Das Neves et al, 2015 andForastiere et al, 2001). Though many epidemiological studies about oral cancer have been done in different parts of India, buccal squamous cell carcinoma was leading subsite in south India but only few studies were carried out in specific subsite of oral cancer.…”
