This study examined coping strategies in head and neck cancer patients. The relationships between the use of approach and avoidant coping strategies and the physical and emotional distress of 35 newly diagnosed head and neck cancer patients during the early stages of cancer treatment were evaluated. Patients were categorized on the basis of coping strategy at the time of diagnosis and then eval...
The expected changes on CT or MRI after treatment of a head and neck cancer are described; it is important not to confuse such expected changes with persisting or recurrent tumour, or a treatment complication. Post-treatment CT or MRI is of value when a recurrent tumour is suspected, to confirm the presence of such a lesion and to determine its extent; this is important information for determin...
BACKGROUND Mixed results exist as to whether positive surgical margins impact survival. The aim of this study was to determine whether positive surgical margins are indeed associated with decreased survival in patients with primary head and neck cancer. METHODS We conducted a retrospective cohort study of 261 cases diagnosed with cancer of the larynx or tongue between 1995 and 1999. Cases wer...
OBJECTIVE Patients with head and neck cancer frequently present to academic tertiary referral centers with imaging studies that have been performed and interpreted elsewhere. At our institution, these outside head and neck imaging studies undergo formal second opinion reporting by a fellowship-trained academic neuroradiologist with expertise in head and neck imaging. The purpose of this study w...
We briefly highlight the growing body of recent evidence linking unprotected oral sex with the development of some types of head and neck cancer in younger patients. These tumours appear to be increasing in incidence although the development of more sensitive methods of HPV detection may be a confounding factor.
PURPOSE To synthesize the direct clinical evidence relating waiting times (WTs) for radiotherapy (RT) to the outcomes of RT. METHODS AND MATERIALS We did a systematic review of the literature between 1975 and 2005 to identify clinical studies describing the relationship between WTs and outcomes of RT. Only high quality (HQ) studies that had adequately controlled for confounding factors were i...
Ablative surgery for malignancies of the upper aerodigestive tract is the most common reason why the reconstructive surgeon is called upon to reconstruct adult head and neck defects. An understanding of the pathophysiology and treatment of head and neck malignancy is vital to the reconstructive surgeon so that restoration of both form and function can be achieved. It is important to understand ...
BACKGROUND Technological advances in military equipment have resulted in more devices being mounted on the helmet to enhance the capability of the soldier. The soldier's neck must bear this head-supported mass (HSM) and the resulting dynamic characteristics of the head and neck system are changed. The purpose of this study was to vary the conditions of impact as well as the design criteria to q...
BACKGROUND Little is known about the diagnosis of head and neck carcinoma in primary care. We sought to estimate the general prevalence of symptoms reported by patients with head and neck carcinomas and to determine the association between detection patterns of head and neck cancer cases in primary care and survival. METHODS In a cross-sectional survey, we used a questionnaire to estimate the...
