Abstract Background To investigate the relationship between radiotherapy (RT) and the risk of cerebrovascular mortality (CVM) in head and neck cancer (HNC) survivors aged ≥ 65 years. Methods Patients with HNC survivors aged ≥ 65 years diagnosed between 2000 and 2012 were included from the Surveillance, Epidemiology, and End Results database. Kaplan–Meier analysis, Log-rank tests, and Cox proportional-hazards regression models were performed for statistical analyses. Results We included 16,923 patients in this study. Of these patients, 7110 (42.0%) patients received surgery alone, 5041 (29.8%) patients underwent RT alone, and 4772 (28.2%) patients were treated with surgery and RT. With a median follow-up time of 87 months, 1005 patients died with cerebrovascular disease. The 10-years CVM were 13.3%, 10.8%, and 11.2% in those treated with RT alone, surgery alone, and surgery plus RT, respectively (P < 0.001). The mean time for CVM was shorter in RT alone compared to surgery alone and surgery plus RT (52 months vs. 56–60 months). After adjusting for covariates, patients receiving RT alone had a significantly higher risk of developing CVM compared to those receiving surgery alone (hazard ratio [HR] 1.703, 95% confidence interval [CI] 1.398–2.075, P < 0.001), while a comparable risk of CVM was found between those treated with surgery alone and surgery plus RT (HR 1.106, 95% CI 0.923–1.325, P = 0.274). Similar trends were found after stratification age at diagnosis, gender, tumor location, and marital status. Conclusions Definitive RT but not postoperative RT can increase the risk of CVM among older HNC survivors. Long-term follow-up and regular screening for CVD are required for HNC patients who received definitive RT to decrease the risk of CVM.

137 Background: Sites of head and neck are associated with chewing, swallowing and speaking. As for treatment of head and neck cancer (HNC), we have to consider organ preservation as well as clinical outcomes. Although non-surgical treatments have been preferred in recent years, complications after treatment have been a concern. The aim of this study was to evaluate the late effects in a cohort of HNC survivors in Utah compared to a matched cohort of cancer free individuals. Methods: Up to 5 cancer free individuals were matched to each HNC survivor on birth year, sex, birth state, and follow up time. Electronic medical records and statewide ambulatory and inpatient surgery data were used to identify late effects over two time periods: 1-5 and 5-10 years after cancer diagnosis. Cox proportional hazards models were used to estimate the risks of late effects. We adjusted for matching factors, race and number of hospital visit. Results: In this study, 2,432 HNC survivors and 12,149 matched controls were enrolled. More than 80% cases had loco-regional disease and a histological type of squamous cell carcinoma. Hazard ratio (HR) for second primary HNC was notably increased among HNC survivors for both 1-5 years (HR: 1498.46; 95% confidence interval (CI), 158.58-14159.69) and 5-10 years (HR: 1509.62; 95% CI, 147.94-15404.15) post cancer diagnosis. And, HRs for respiratory disease, including respiratory system, lung cancer and pneumoniae, were also increased among HNC survivors for both 1-5 years and 5-10 years post cancer diagnosis. As for hearing loss, HNC survivors had a increased HR for 1-5 years post cancer diagnosis (HR: 5.90; 95% CI, 2.67-13.01) and this association was consistent for 5-10 years post cancer diagnosis (HR: 5.01; 95% CI, 2.06-12.18). Conclusions: In this study, we found HNC survivors have notable associations with second primary HNC, smoking related respiratory disease, and hearing loss which might be associated with chemotherapy when compared to cancer free subjects.

Abstract Background The rapidly increasing coincidence of thyroid cancer and metabolic syndrome (MS) in recent decades suggests an association between the two disorders. To investigate this association, we conducted a nationwide study of a large-scale patient cohort. Methods Between 2009 and 2011, data were collected by the Korean National Health Insurance Service for 4,658,473 persons aged 40–70 years without thyroid cancer. During the 6-year follow-up period, participants were monitored for the development of thyroid cancer. The relative risks and incidences of thyroid cancer were calculated using multivariate Cox proportional hazards regression analyses after adjusting for age and body mass index. Results At the end of the study, 47,325 subjects (1.0%) were newly diagnosed with thyroid cancer. The risk of thyroid cancer was significantly elevated in men and women with MS or MS components, except for hyperglycaemia (p = 0.723) or hypertriglyceridemia (p = 0.211) in men. The incidence of thyroid cancer per 10,000 person-years in individuals with MS was significantly higher in men (6.2, p < 0.001) and women (21.3, p < 0.001) compared to those without MS. Additionally, the risk of thyroid cancer increased significantly with an increasing number of MS components even in individuals with only one or two MS components. Conclusions MS and its components were significantly associated with increased risk of developing thyroid cancer. Patients with MS or MS components should be regularly screened for thyroid cancer to enable swift therapeutic response in this at-risk population.

Purpose This study aimed to determine the risk and time trends of herpes zoster among patients with head and neck cancer, with or without radiotherapy. Methods A total of 2160 patients with head and neck cancer were enrolled. The radiotherapy and non- radiotherapy cohorts were frequency-matched at a 1:1 ratio according to sex, age, and index date. Moreover, 1080 matched non-cancer individuals were considered normal controls. Data were obtained from the National Health Insurance Research Database and Cancer Registry. The primary end point was the incidence of herpes zoster, and the adjusted confounding factors were age, sex, comorbidities, oncological surgery, and chemotherapy. Results The incidence of herpes zoster was higher in cancer patients than in non-cancer individuals but did not significantly differ (13.67 vs. 8.06 per 1,000 person-years, p = 0.18). The risk of herpes zoster was significantly higher in the radiotherapy cohort than in the non-radiotherapy cohort (18.55 vs. 9.06 per 1,000 person-years, p = 0.03). The 5-year incidence rates in the radiotherapy and non-radiotherapy cohorts were 8.9% and 5%, respectively (p < 0.0001). Survival analysis indicated there was no immortal time bias. The time trends in the radiotherapy cohort persistently showed a high risk within the first 2 years, which decreased thereafter. Only patients with comorbid rheumatoid arthritis showed a significantly high risk of herpes zoster (p = 0.02). Oncological surgery and chemotherapy had no impact on the development of herpes zoster. Conclusions This nationwide population-based study showed that patients with head and neck cancer receiving radiotherapy are at an increased risk of herpes zoster. Health care professionals should pay more attention to this vulnerable group to improve their quality of life.

Abstract Visual impairment has emerged as a potential modifiable risk factor for dementia. However, there are a lack of large studies with objective measures of vison and with more than ten years of follow-up. We investigated whether visual impairment is associated with an increased risk of incident dementia in UK Biobank and EPIC-Norfolk. In both cohorts, visual acuity was measured using a “logarithm of the minimum angle of resolution” (LogMAR) chart and categorised as no (≤0.30 LogMAR), mild (&gt;0.3 - ≤0.50 LogMAR), and moderate to severe (&gt;0.50 LogMAR) impairment. Dementia was ascertained through linkage to electronic medical records. After restricting to those aged ≥60 years, without prevalent dementia and with eye measures available, the analytic samples consisted of 62,206 UK Biobank and 7,337 EPIC-Norfolk participants, respectively. In UK Biobank and EPIC-Norfolk. respectively, 1,113 and 517 participants developed dementia over 11 and 15 years of follow-up. Using multivariable cox proportional-hazards models, the hazard ratios for mild and moderate to severe visual impairment were 1.26 (95% Confidence Interval [CI] 0.92-1.72) and 2.16 (95% CI 1.37-3.40), in UK Biobank, and 1.05 (95% CI 0.72-1.53) and 1.93 (95% CI 1.05-3.56) in EPIC-Norfolk, compared to no visual impairment. When excluding participants censored within 5 years of follow-up or with prevalent poor or fair self-reported health, the direction of the associations remained similar for moderate impairment but were not statistically significant. Our findings suggest visual impairment might be a promising target for dementia prevention, however the possibility of reverse causation cannot be excluded.
