“…Head and neck cancer (HNC) includes a broad spectrum of malignancies, anatomically related but different in terms of management, accounting for about 4% of cancer incidence in Europe . Imaging plays a crucial role in the diagnostic evaluation of patients affected by HNC, being able to add pivotal information related to diagnosis, staging, and response to therapy, significantly contributing to improve HNC prognosis . Advanced cross‐sectional imaging modalities enable radiologists to assess disease extent, its spread to neighboring structures and local lymph nodes, perineural or perivascular spread, and bone invasion, as well as to identify distant metastases and the presence of relevant comorbidities.…”

BackgroundDiagnostic imaging guidelines are increasingly embraced in oncologic imaging in order to improve examinations appropriateness and technical quality. The usefulness of guidelines employment in clinical practice is dramatically related to the quality of the guidelines themselves. However, an extreme variability in guidelines’ quality may occur. Following a European Network for the Assessment of Imaging in Medicine (EuroAIM) initiative, the aim of this study was to assess the quality of the available guidelines regarding head and neck cancer (HNC) imaging.MethodsA literature search was conducted to identify imaging guidelines focused on HNC. Selected guidelines were evaluated by four independent appraisers using the Appraisal of Guidelines for Research & Evaluation version 2.0 (AGREE II) tool, which comprises 23 key items, rated on a 7‐point scale (1—strongly disagree to 7—strongly agree) and organized within six domains. For each domain, the intraclass correlation coefficient (ICC) was used to assess the agreement among appraisers’ scores.ResultsAfter literature search, three guidelines were selected and evaluated. One guideline scored “average” as overall quality, while the remaining two scored a “low” overall quality. The highest result (total score = 75.0% ± 19.3%) was obtained in domain 4 (Clarity of presentation) while the lowest (total score = 27.1% ± 4.2%) in domain 6 (Editorial independence). ICC analysis showed a very good agreement (range: 0.932‐0.961) among the four appraisers.ConclusionsOur results showed a heterogeneous quality of existing guidelines in HNC imaging. Issues raised from this appraisal should be considered when developing future guidelines on HNC imaging.

“…The most common age group was 51–60 yrs (46.62%) in malignant lesions, and slightly younger in the inflammatory pathologies of the suprahyoid neck spaces. Past studies [21,22] have revealed that squamous cell carcinoma is five times more common in men than in women, and mainly patients in the age group of 50 to 60 years are affected. The nature of the lesion predicted by computed tomography correlated well with surgical findings in this study, which was similar to the study done by Gupta et al [9] in which CT correctly predicted the benign or malignant nature of lesions in 33/34 patients.…”

SummaryBackgroundSuprahyoid neck lesions are difficult to assess only by means of clinical inspection and therefore imaging techniques are required to precisely evaluate suprahyoid neck spaces. The aim of this study was to evaluate the distinctive role of computed tomography in the assessment of anatomical source and pathological type of masses involving the suprahyoid neck spaces.Material/MethodsSixty patients presenting with suprahyoid neck masses underwent computed tomography of the neck. The CT findings were correlated with histopathological findings and a final diagnosis was made.ResultsOverall, male preponderance was seen except in the case of parotid space lesions where female predominance was seen. The most common aetiology was squamous cell carcinoma and the majority of cases (30%) were seen in patients aged 41–50 years. The majority of lesions were found in the pharyngeal mucosal space (n=16) with squamous cell carcinoma being the most common pathology. In the parotid space, pleomorphic adenoma and in the prestyloid parapharyngeal space, squamous cell carcinoma were the most common lesions, respectively. In the retropharyngeal space, an equal incidence of malignant and inflammatory aetiologies was seen. Abscesses were the most common lesions in the prevertebral space. The pleomorphic adenoma was the most common benign tumour and was also the second most common tumour in the suprahyoid neck spaces. CT had an excellent correlation with histopathological findings with sensitivity of 96.4%, specificity of 100%, positive predictive value of 100% and a negative predictive value of 91.67%.ConclusionsComputed tomography definitely has a major role to play in the evaluation of suprahyoid neck masses as it has an excellent correlation with post-operative histopathological diagnosis.

Background: Overview of clinical impact of positron emission tomography-computed tomography (PET-CT) scans in patients with head and neck carcinomas at our center. Methods: Retrospective review of posttreatment 18F-fluorodeoxyglucose (18F-FDG) PET-CT scans in patients with head and neck carcinomas with risk of residual disease. Clinical outcome served as the reference standard. Results: This study included 93 patients (65.6% males, mean age: 48.8 years ± 17.2 standard deviation) with squamous cell carcinoma as most frequent histopathology (91.4%). PET-CT scans were performed on average 6 months posttreatment. Diagnostic accuracy, positive predictive value, and negative predictive value of PET-CT for disease were found to be 88%, 88%, and 92%, respectively. A median follow-up of 24 months was available for 91 patients. Kaplan–Meier curves showed significantly higher disease-free survival with negative PET-CT as compared to positive PET-CT (P = 0.01) and maximum standardized uptake values of <5.0 (P = 0.01). Conclusion: FDG PET-CT has diagnostic and prognostic implications in treated patient of head and neck cancers.
