Utility of ultrasound-guided fine needle aspiration cytology in assessing malignancy in head and neck pathology.

OBJECTIVE: Fine needle aspiration cytology (FNAC) is a well-established diagnostic procedure for head and neck masses not clearly originating from mucosal or cutaneous surfaces. We analysed head and neck masses evaluated over a 2-year period, to assess the reliability of FNAC for the evaluation of malignancy. METHODS: We enrolled all patients undergoing FNAC, from April 2013 to July 2015, in a single service of a large Italian university hospital. Relevant clinical data and ultrasonographic parameters of the lesions were recorded. We performed both conventional and thin-prep smears. Clinical presentation, ultrasonographic features and final cytology diagnoses were analysed and correlated with histology. RESULTS: The series included 301 lesions in 285 patients, with a single (94.4%) or two (5.6%) lesions. Only eight samples were considered non-diagnostic/inadequate (2.6%). Among the cases, 139 FNAC (46.1%) underwent surgery. Cytological-histological correspondence was found in 89% of the cases. Concerning malignancy, we documented less than 4% false positives and less than 2.5% false negatives, with 92.7% sensitivity and 94.6% specificity. CONCLUSION: FNAC diagnosis can be highly specific. Most importantly, it is highly reliable in assessing malignancy, thus defining the priority and guiding the management procedures.

Tumour stage and gender predict recurrence and second primary malignancies in head and neck cancer: a multicentre study within the INHANCE consortium.

Recurrence and second primary cancer (SPC) continue to represent major obstacles to long-term survival in head and neck cancer (HNC). Our aim was to evaluate whether established demographics, lifestyle-related risk factors for HNC and clinical data are associated with recurrence and SPC in HNC. We conducted a multicentre study by using data from five studies members of the International Head and Neck Cancer Epidemiology consortium-Milan, Rome, Western Europe, Sao Paulo, and Japan, totalling 4005 HNC cases with a median age of 59 (interquartile range 52-67). Multivariate hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated for recurrence and SPC. During follow-up, 1161 (29%) patients had recurrence and 343 (8.6%) developed SPC. Advanced tumour stage was associated with increased risk of recurrence in HNC overall (HR = 1.76, 95% CI 1.41-2.19). Women with laryngeal cancer had a reduced risk of recurrence compared to men (HR = 0.39, 95% CI: 0.24-0.74). Concerning predictors of SPC, advanced age (HR = 1.02; 95% CI: 1.00-1.04) and alcohol consumption (> 1 drink per day, HR = 2.11; 95% CI: 1.13-3.94) increased the risk of SPC among patients with laryngeal cancer. Additionally, women were at higher risk of SPC, in HNC overall group (HR = 1.68; 95% CI: 1.13-2.51) and oropharyngeal cancer group (HR = 1.74; 95% CI: 1.02-2.98). Tumour stage and male gender (larynx only) were positive predictors of cancer recurrence in HNC patients. Predictors of SPC were advanced age and alcohol use among laryngeal cancer cases, and female gender for oropharyngeal and HNC overall.

Adult height and head and neck cancer: a pooled analysis within the INHANCE Consortium.

Several epidemiological studies have shown a positive association between adult height and cancer incidence. The only study conducted among women on mouth and pharynx cancer risk, however, reported an inverse association. This study aims to investigate the association between height and the risk of head and neck cancer (HNC) within a large international consortium of HNC. We analyzed pooled individual-level data from 24 case-control studies participating in the International Head and Neck Cancer Epidemiology Consortium. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated separately for men and women for associations between height and HNC risk. Educational level, tobacco smoking, and alcohol consumption were included in all regression models. Stratified analyses by HNC subsites were performed. This project included 17,666 cases and 28,198 controls. We found an inverse association between height and HNC (adjusted OR per 10 cm height = 0.91, 95% CI 0.86-0.95 for men; adjusted OR = 0.86, 95% CI 0.79-0.93 for women). In men, the estimated OR did vary by educational level, smoking status, geographic area, and control source. No differences by subsites were detected. Adult height is inversely associated with HNC risk. As height can be considered a marker of childhood illness and low energy intake, the inverse association is consistent with prior studies showing that HNC occur more frequently among deprived individuals. Further studies designed to elucidate the mechanism of such association would be warranted.

Recreational physical activity and risk of head and neck cancer: a pooled analysis within the international head and neck cancer epidemiology (INHANCE) Consortium.

Increasing evidence suggests that physical activity could prevent cancer, but scanty data is available on head and neck cancer (HNC). The aim of our study is to clarify the effect of recreational physical activity (rPA) on HNC. We analyzed data from four case-control studies, including 2,289 HNC cases and 5,580 controls. rPA was classified as: none/low (reference group), moderate and high. We calculated summary Odds Ratios (ORs) by pooling study-specific ORs. Overall, moderate rPA was associated with 22% lower risk of HNC compared to those with none or very low rPA levels [OR = 0.78, 95% Confidence Interval (95% CI): 0.66, 0.91]. Moderate rPA is associated with reduced risk of oral (OR = 0.74, 95% CI: 0.56, 0.97) and pharyngeal cancer (OR = 0.67, 95% CI: 0.53, 0.85), as well as high rPA levels (OR = 0.53, 95% CI: 0.32, 0.88 for oral cavity, OR = 0.58, 95% CI: 0.38, 0.89 for pharynx). High rPA levels, however, is associated with higher risk of laryngeal cancer (OR = 1.73, 95% CI: 1.04, 2.88). Stratified analyses showed that such inverse association between moderate rPA and HNC was more evident among males (OR = 0.75, 95% CI: 0.62, 0.90), subjects ≥45 years (OR = 0.78, 95% CI: 0.66, 0.93), and ever smokers and ever drinkers (OR = 0.72, 95% CI: 0.59, 0.88). High rPA significantly reduces HNC risk among subject ≥45 years (OR = 0.66, 95% CI: 0.48, 0.91). Promoting rPA might be inversely associated with HNC.

Vocal fold nodules in school age children: attention deficit hyperactivity disorder as a potential risk factor.

OBJECTIVE: To evaluate the presence of symptoms of inattention and hyperactivity/impulsivity in a population of school age children affected by vocal fold nodules. METHODS: Parents and teachers of 18 children with vocal fold nodules (10 males, eight females; aged between 6 and 12 years) and 20 matched controls without dysphonia and/or vocal fold diseases (11 males, nine females; aged between 6 and 12 years) completed Attention-Deficit/Hyperactivity Disorder (ADHD) rating scale for parents (SDAG [Scala per i Disturbi di Attenzione/Iperattività per Genitori]) and teachers (SDAI [Scala per i Disturbi di Attenzione/Iperattività per Insegnanti) rating scales containing in two subscales items that specifically evaluate the symptoms of ADHD according to the DSM-IV. All children were subjected to videolaryngoscopy. RESULTS: The group with vocal fold nodules scored significantly higher than the controls; the difference between the two groups was statistically significant for both the subscales of both questionnaires (SDAG and SDAI) (P < 0.05). Four children in the group with vocal fold nodules who scored higher than 14 in at least one subscale were referred for psychiatric evaluation. For two of the children, both male, a diagnosis of combined ADHD was formulated. CONCLUSIONS: ADHD is a possible risk factor for the development of vocal fold nodules in childhood. SDAG and SDAI rating scales may supplement the diagnostic assessment of children with vocal fold nodules.

Clinical features and prognostic factors in patients with head and neck cancer: Results from a multicentric study.

BACKGROUND: The purpose of this study is to evaluate whether demographics, lifestyle habits, clinical data and alcohol dehydrogenase polymorphisms rs1229984 and rs1573496 associated with first primary head and neck (HNC) are associated with overall survival, recurrence, and second primary cancer (SPC). METHODS: We conducted a follow-up study in five centres including 801 cases. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated for overall survival, recurrence and SPC. RESULTS: Five-years overall survival was 62% for HNC cases, 55% for oral cavity, 53% for oropharynx, 41% for hypopharynx, and 71% for larynx. Predictors of survival were older ages (HR=1.18 for 5 years increase; CI: 1.07-1.30), higher tumour stage (HR=4.16; CI: 2.49-6.96), and high alcohol consumption (HR=3.93; CI: 1.79-8.63). A combined therapy (HR=3.29; CI: 1.18-9.13) was associated with a worst prognosis for oral cavity cancer. The only predictor was higher tumour stage (HR=2.25; CI: 1.26-4.03) for recurrence, and duration of smoking (HR=1.91; CI: 1.00-3.68) for SPC. ADH1B rs1229984 polymorphism HRs for HNC and oesophageal cancer death and for alcohol related cancer death were 0.67 (95% CI: 0.42-1.08), and 0.64 (95% CI: 0.40-1.03), respectively. CONCLUSIONS: The survival expectation differs among HNC sites. Increasing age and stage, and high alcohol consumption were unfavourable predictors of HNC survival overall. Duration of tobacco consumption before the first primary tumour was a risk factor for SPC.
