July 2013The study included 631 patients with LPSCC, 468 of whom had pharyngeal cancer and 163 with vocal laryngeal cancers. Additionally, 1,234 individuals with no history of cancer were included as controls.
Participants completed a questionnaire detailing their sociodemographic information, and history of smoking, alcohol consumption and heartburn. After adjusting for age, gender, race, smoking, alcohol consumption, HPV16 seropositivity, education and body mass index, the researchers found that participants who weren’t heavy smokers or drinkers and who had a history of frequent heartburn were linked to a 78 percent increased risk of LPSCC, compared with the control group.
