Tumour-infiltrating lymphocytes predict for outcome in HPV-positive oropharyngeal cancer
2014
Background:
Human papillomavirus (HPV)-positive oropharyngeal cancer (OPSCC) is associated with improved survival compared with HPV-negative disease. However, a minority of HPV-positive patients have poor prognosis. Currently, there is no generally accepted strategy for identifying these patients.
Methods:
We retrospectively analysed 270 consecutively treated OPSCC patients from three centres for effects of clinical, pathological, immunological, and molecular features on disease mortality. We used Cox regression to examine associations between factors and OPSCC death, and developed a prognostic model for 3-year mortality using logistic regression analysis.
Results:
Patients with HPV-positive tumours showed improved survival (hazard ratio (HR), 0.33 (0.21–0.53)). High levels of tumour-infiltrating lymphocytes (TILs) stratified HPV-positive patients into high-risk and low-risk groups (3-year survival; HPV-positive/TIL
high
=96%, HPV-positive/TIL
low

low
patients did not differ from HPV-negative patients (HR, 1.01;
P
=0.98). We developed a prognostic model for HPV-positive tumours using a ‘training’ cohort from one centre; the combination of TIL levels, heavy smoking, and T-stage were significant (AUROC=0·87). This model was validated on patients from the other centres (detection rate 67%; false-positive rate 5.6%; AUROC=0·82).
Interpretation:
Our data suggest that an immune response, reflected by TIL levels in the primary tumour, has an important role in the improved survival seen in most HPV-positive patients, and is relevant for the clinical evaluation of HPV-positive OPSCC.

Background
Neck metastasis is the most important prognostic factor in oral cavity squamous cell carcinomas (SCC). Apart from the T- stage, depth of invasion has been used as a highly predictable factor for microscopic neck metastasis, despite the controversy on the exact depth cut off point. Depth of invasion can be determined clinically and radio logically. However, there is no standard tool to determine depth of invasion preoperatively. Although MRI is used widely to stage the head and neck disease, its utility in depth evaluation has not formally been assessed.
Objective
To compare preoperative clinical and radiological depth evaluation in oral tongue SCC using the standard pathological depth.
To compare clinical and radiological accuracy between superficial (<5 mm) vs. deep invaded tumor (≥5 mm)
Methods
This prospective study used consecutive biopsy-proven oral tongue invasive SCC that presented to the University health network (UHN), Toronto. Clinical examination, radiological scan and appropriate staging were determined preoperatively. Standard pathology reports postoperatively were reviewed to determine the depth of invasion from the tumor specimen.
Results
72 tumour samples were available for analysis and 53 patients were included. For all tumors, both clinical depth (
r
= 0.779;
p
< 0.001) and radiographic depth (
r
=0.907;
p
<0.001) correlated well with pathological depth, with radiographic depth correlating slightly better. Clinical depth also correlated well with radiographic depth (
r
= 0.731;
p
< 0.001). By contrast, for superficial tumors (less than 5 mm on pathological measurement) neither clinical (
r
= 0.333,
p
= 0.34) nor radiographic examination (
r
= − 0.211;
p
= 0.56) correlated with pathological depth of invasion.
Conclusion
This is the first study evaluating the clinical assessment of tumor thickness in comparison to radiographic interpretation in oral cavity cancer. There are strong correlations between pathological, radiological, and clinical measurements in deep tumors (≥5 mm). In superficial tumors (<5 mm), clinical and radiological examination had low correlation with pathological thickness.

Comparison of techniques for identification of peripheral vestibular nystagmus
2012
To determine the best clinical method for identifying peripheral vestibular nystagmus, by comparing eye movement examination with optic fixation, and with fixation removed using Frenzel's glasses, infra-red video-Frenzel's goggles or an ophthalmoscope, with results of electronystagmography.
One hundred patients referred for electronystagmography from the audiovestibular medicine clinic at Queen Alexandra Hospital, Portsmouth, were examined immediately before undergoing electronystagmography.
Video-Frenzel's goggles were highly effective at detecting peripheral vestibular nystagmus, with a sensitivity of 85 per cent (95 per cent confidence interval, 62.1-96.8 per cent) and a specificity of 65 per cent (53.5-75.3 per cent), compared with electronystagmography. Ophthalmoscopy had comparable sensitivity to Frenzel's glasses (used in the dark), i.e. 26.3 per cent (9.1-51.2 per cent) compared with 31.6 per cent (12.6-56.6 per cent), respectively. Frenzel's glasses as normally used in ENT clinics (i.e. in dim lighting) were ineffective, with a sensitivity of just 10 per cent (1.2-31.7 per cent).
Video-Frenzel's goggles should be used in all clinics with substantial numbers of balance-impaired patients. Traditional Frenzel's glasses have no place in clinical practice unless formal black-out facilities are available.

Head & neck cancer
2018
Up to 70 per cent of the population search online for medical or health-related information. This study aimed to assess the quality of online health resources available to educate patients on a variety of otolaryngological conditions.
Two clinicians independently analysed the quality and content of educational websites (patient.co.uk and wikipedia.org) for common and uncommon diagnoses, with cancerresearchuk.org also used to assess two head and neck cancers.
Cancerresearchuk.org, followed by patient.co.uk, scored most highly in their ability to inform readers on a selection of otolaryngological conditions. Although wikipedia.org was less likely to include all relevant information and was more difficult to read, it still provided mostly accurate information.
Where possible, patients should be advised to access professionally maintained health information websites (patient.co.uk and cancerresearchuk.org). However, wikipedia.org can provide adequate information, although it lacks depth and can be difficult to understand.

Background/Aim: There is significant variation in post-treatment surveillance imaging for sinonasal malignancies. This study examined the utility of surveillance imaging in detecting recurrence in patients treated for sinonasal malignancies. Patients and Methods: We performed a retrospective review on an IRB-approved dataset of patients with sinonasal malignancies treated at a single institution between 2005 to 2021. Patients were categorized into groups based on the frequency of annual imaging and total number of imaging studies. We compared time-to-recurrence between the groups using log-rank test. A two-sided p-value of <0.05 was considered as the threshold for significance. Results: A total of 93 patients were eligible for this study with a median follow up of 42.3 months and 25.8% (n=24) of patients had documented recurrence. Sensitivity and specificity for recurrence based on computed tomography (CT) scans within one year of treatment completion were 50.0% and 19.5%; positron emission tomography/CT was 90.0% and 19.5%; and magnetic resonance imaging was 60.0% and 61.0%, respectively. Regardless of the type of imaging, symptomatic presentation after treatment had a specificity of 91.0% with a positive likelihood ratio of recurrence of 2.95 (95%CI=1.06-8.22). The frequency of scans was not associated with the risk of recurrence (HR=0.55; 95%CI=0.23-1.29, p=0.17). Similarly, no association was noted between the total number of scans and risk of recurrence (HR=0.64; 95%CI=0.27-1.51, p=0.31). Conclusion: The total number of frequency of scans within the first year after treatment had no association with time to recurrence of sinonasal malignancies. Symptomatic presentation was strongly associated with recurrence and should be investigated with appropriate imaging.

The Relationship Between Loneliness and Interpersonal Trust During Middle Childhood
2004
The authors administered measures of loneliness, generalized trust beliefs in peers, and trust beliefs in specific familiar peers (i.e., opposite-gender peers, same-gender peers, close same-gender peers) to a sample of 63 children (33 girls, 30 boys) from 4th and 5th grades (M age = 10 years, 6 months). They assessed children's trusting behavior by engaging them in a Prisoner's Dilemma game (reciprocal trusting) and by evaluating teachers' ratings. The authors found that, across gender, loneliness was negatively correlated with each measure of trust beliefs and trusting behavior. As expected, the relationship between children's loneliness and trust, specifically trust beliefs in same-gender peers, was stronger for girls than for boys. In support of an additive risk model, the authors found low trust beliefs in same-gender peers and low reciprocal trusting behavior with peers each statistically contributed to loneliness in girls.
