title: Factors related to advanced stage oral squamous cell carcinoma in southern Thailand.
abstract: A critical factor that indicates a poor prognosis of oral squamous cell carcinoma (OSCC) is advanced stage disease. This study, therefore, aimed to identify the factors related to advanced stage (TNM staging III, IV) OSCC in Thailand. There were 161 patients with squamous cell carcinoma of the oral cavity and lip (ICD-9 140, 141, 143-5), included in the study. Sixty-two per cent of the patients presented with advanced stage disease. Information on demographic characteristics, risk habits, health-seeking behaviour prior to health care professional (HCP) consultation, tumour characteristics and patient and professional delay was obtained by questionnaire-based interview of the patients. These variables were included as initial variables in a logistic regression to calculate the odds ratio (OR) of advanced versus early stage OSCC. Having traditional herbal medication before HCP consultation significantly increased the risk of advanced stage OSCC (OR 5.77; 95% C.I. 1.25-26.62). Floor of mouth location of tumour was associated with a lower risk of advanced stage disease (OR 0.27; 95% C.I. 0.09-0.82) as was having an ulcer (OR 0.43, 95% C.I. 0.02-0.89). The findings indicate that having traditional herbal medication before HCP consultation increased the risk of advanced stage disease. The lower risk of advanced stage OSCC associated with ulcerative tumours and those on the floor of the mouth may be due to their being more readily detected by the patients.
