Abstract: Background: Betel quid chewing and cigarette smoking are two of
the risk factors for some dental diseases as well as oral cavity cancer in Taiwan.
The aim of the study was to quantify these factors in oral cavity cancer patients
and compare the prevalence of these factors in patients and the general
population. Methods: A questionnaire was designed to evaluate betel quid
chewing, cigarette smoking and alcohol drinking in 254 patients, who had
squamous cell carcinoma of the oral cavity, and had received surgical excision
at the Changhua Christian Hospital in Taiwan between 2005 and 2008. The
results were compared with those of population of Taiwan, based on a nationwide
survey with sample of 26 744 people. Results: We found that more than
80% of the male patients were both betel quid chewers and smokers. Few
women in the survey practiced betel quid chewing, cigarette smoking or alcohol
drinking. Chewers and smokers usually started the habits in their 20s. On
average, a chewer patient consumed 12 508 betel quid pieces per year, for
23.3 years before the diagnosis of oral cavity cancer, making the total amount of
betel quid consumed nearly 310 000 pieces; and a smoker patient consumed 469
packs per year, for 28.5 years before diagnosis, making the total number of
about 14 000 packs. Patients with both habits had the age at diagnosis 4 years
earlier than the smoker-only patients, 5 years earlier than the chewer-only
patients, and 6 years earlier than those with neither. Conclusions: On average,
it took two decades of betel quid chewing and cigarette smoking before oral
cavity cancer diagnosis, making the life-time consumption of these substances
an astonishing amount. Betel quid chewing and cigarette smoking patients are
more likely to be diagnosed with oral cavity cancer at a younger age than those
who have just one habit or none. Patients that smoke more are not only more
likely to be diagnosed at a younger age, but also at an advanced stage.
