Alcohol consumption is associated with improved health-related quality of life in head and neck cancer patients.

The study aim was to investigate the relationship between alcohol consumption and health-related quality of life (HRQL) in post-therapeutic head and neck cancer patients. A cross-sectional study design was used with a sample of 191 subjects. Data were collected through interview and chart review. Alcohol consumption was evaluated through the dichotomous response to the question "During the past month have you drunk alcohol on one or more occasions?" HRQL was evaluated through the EORTC QLQ-C30 and H&N35 instruments. Data were also collected concerning sociodemographic and clinical variables. Multivariate regression was used to evaluate the hypothesized association. Of 28 domains comprising the EORTC QLQ-C30 and H&N35 instruments, eight were significantly associated with alcohol consumption, while 19 of the 20 remaining domains showed a tendency towards an association. Alcohol drinking was associated with significantly better physical and role functioning, and better global HRQL, plus less fatigue, pain, problems swallowing, dry mouth and feelings of illness. This suggests that, while the study findings are limited by its design and the sample bias, despite alcohol's role as an aetiological factor, it may be reasonable to drink a little as one recovers from head and neck cancer.
