Squamous cell carcinoma of the oral cavity and oropharynx in patients aged 18 45 years: A case control study to evaluate the risk factors with emphasis on stress, diet, oral hygiene, and family history.
BACKGROUND Increasing incidence of squamous cell carcinoma (SCC) of the oral cavity and oropharynx is reported in young adults. However, there is a paucity regarding etiology and risk factors. AIM To evaluate the exposure potential carcinogenic factors among a sample aged 45 years and younger, diagnosed with SCC of the oral cavity and oropharynx. METHODOLOGY Eighty five case samples aged 18 45 years, diagnosed with SCC of the oral cavity and oropharynx were compared with 85 controls who had never had cancer, matched for age and sex. This study was conducted by questionnaire based interviews. Questionnaire contained items about exposure to the following risk factors: Caries prevalence, oral hygiene status, dental trauma, dental visit, stress, family history of cancer, environmental exposure to potential carcinogens, diet, body mass index (BMI) habits such as smoking, tobacco chewing, betel quid/pan, or supari. STATISTICAL ANALYSIS Odds ratios (ORs) of oral and pharyngeal cancer and the corresponding 95% confidence intervals were estimated using multiple logistic regression models. P< 0.05 was considered statistically significant. RESULTS Elevated OR was seen in young adults who had poor oral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid for 11 20 years. CONCLUSIONS An increased risk of oral and pharyngeal cancer was seen in cases who had poor oral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid.
