Bossi P, et al. - A total of 129 individuals were analyzed to estimate the prevalence of fatigue and its interference with daily life activities and also to examine the relationship between fatigue and sex, age, primary tumor site, human papillomavirus (HPV) status, past oncologic treatment, and time since end of treatment from February 2015 to July 2016. Researchers of this study noted that oropharynx (46%, with 4/5 cases HPV positive), nasopharynx (22%), larynx/hypopharynx (14%), oral cavity (13%), and paranasal sinus or salivary gland (5%) were the primary sites of cancer. They noted that oncologic therapy was completed 12-96 months earlier. In addition, they observed mild fatigue in 67% of subjects, moderate in 11%, and severe in 7% whereas fatigue was absent in 15% of the patients. They did not record any relationship between the Brief Fatigue Inventory average score and the analyzed variables.
