RESUMEN
OBJECTIVES: To analyze the long-term side effects of radiation therapy (RT) for head and neck cancer (HNC). METHODS: Retrospective chart analysis of all 688 HNC patients treated during 2010-2015 at Turku University Hospital, Finland. All patients who survived for more than a year after RT/chemoRT were included (n = 233). Intensity modulated RT (IMRT) with standard fractionation was applied in each case. RESULTS: One hundred and six patients (45%) reported persisting dysphagia, for which neck RT increased risk. Definitive neck RT to high-risk volume did not increase late toxicity risks compared to elective neck RT. Radiation-induced hypothyroidism (29%, n = 67) was more common among younger patients and females. Osteoradionecrosis (12%, n = 29) was more common in the oral cavity cancer group (20.7%, n = 92) compared to all other subsites. CONCLUSIONS: Late toxicities of RT for HNC are common. Age, gender, tumor subsite, and neck RT affect susceptibility to long-term side effects. LEVEL OF EVIDENCE: 4.
RESUMEN
BACKGROUND: The purpose of this retrospective study was to present our assessment of modifiable perioperative factors for major cardiac and cerebrovascular events (MACCE). METHODS: This study included an unselected cohort of patients with head and neck cancer (n = 456) treated in Turku University Hospital between 1999 and 2008. RESULTS: Perioperative and postoperative univariate predictors of MACCE at 30-day follow-up were: total amount of fluids (during 24 hours) over 4000 mL, any red blood cell (RBC) infusion, treatment in the intensive care unit (ICU), tracheostomy, and microvascular reconstruction surgery. Median time from operation to MACCE was 3 days. Patients receiving >4000 mL of fluids had MACCE more often compared with those receiving <4000 mL (10.8% vs 2.4%; p < .001, respectively). Moreover, every RBC unit transfused or every liter of fluid administered over 4000 mL/24h increased the risk of MACCE 18% per unit/liter, respectively. CONCLUSION: Patients with head and neck cancer receiving excessive intravenous fluid administration perioperatively and postoperatively are at high risk for cardiac complications, especially heart failure. © 2016 Wiley Periodicals, Inc.

Incidence and predictors of peri-operative or post-operative cardiovascular complications in head and neck cancer surgery remain poorly elucidated. In this retrospective study, we investigated the rate and pre-operative risk factors for cardiovascular and cerebrovascular complications. This study included all patients (n = 456) operated for head and neck cancer between 1999 and 2008. Patients' medical records were reviewed and the adjudication of endpoints was performed by adjudication committee. The 30-day incidence of cardiovascular and cerebrovascular complications was 7.2 %. Cardiac mortality at 30 days was 1.0 %. Univariate predictors of MACCE (major adverse cardiac and cerebrovascular events) at the 30-day follow-up were history of myocardial infarction (OR 4.56, 95 % CI 1.73-11.97, p = 0.002); history of heart failure (OR 4.14, 95 % CI 1.32-13.02, p = 0.015); pre-existing coronary artery disease (OR 3.98, 95 % CI 1.75-9.06, p = 0.001); prior aspirin medication (OR 3.73, 95 % CI 1.81-7.71, p < 0.001); prior betablocker medication (OR 3.67, 95 % CI 1.79-7.51, p < 0.001); hypertension (OR 2.55, 95 % CI 1.25-5.19, p = 0.010); and increasing age (OR 1.08, 95 % CI 1.05-1.12, p < 0.001). In a multivariate model, independent predictors of MACCE were pre-existing coronary artery disease (OR 2.45, 95 % CI 1.03-5.80, p = 0.042) and increasing age (OR 1.08, 95 % CI 1.04-1.11, p < 0.001). Patients having surgery for head and neck cancer are at high (>5 %) risk of developing vascular complications. Prior coronary artery disease and increasing age are independent risk factors for MACCE.
