The impact of computed tomography-defined sarcopenia on outcomes in head and neck cancer has been well described. Sarcopenic obesity (SO) (depleted muscle mass combined with obesity) may pose a more serious risk than either condition alone. We investigated SO and its impact on survival and critical weight loss (≥ 5 %) in patients with head and neck cancer who received curative radiotherapy (± other modalities). Retrospective analysis of computed tomography cross-sectional muscle at cervical (C3), thoracic (T2) and lumbar (L3) regions was conducted. Patients were grouped by BMI and sarcopenia status based on established thresholds. A total of 413 patients were included for analysis, the majority having oropharyngeal carcinoma (52 %), and 56 % received primary concurrent chemoradiotherapy. The majority of the cohort (65 %) was overweight or obese (BMI ≥ 25 kg/m2). Sarcopenia was found in 43 %, with 65 % having SO (n 116), equating to 28 % of the whole cohort. Critical weight loss was experienced by 58 % (n 238). A significantly higher proportion of patients with SO experienced critical weight loss (n 70 v. 19, P < 0·001) and were four times more likely to do so during treatment (OR 4·1; 95 % CI 1·5, 7·1; P = 0·002). SO was not found to impact on overall or cancer-specific survival; however, in patients with sarcopenia, those with SO had better overall survival (median 9·1 v. 7·0 years; 95 % CI 5·2, 16·8; P = 0·021). SO at the time of presentation in patients with head and neck cancer is predictive of critical weight loss during treatment, and muscle evaluation can be useful in identifying patients at nutritional risk regardless of BMI and obvious signs of wasting.

Background: Late‐stage progressive decline of swallowing function after radiotherapy for head and neck cancer (HNC) is often difficult to monitor. This study examined the feasibility and clinical outcomes of speech‐language pathology implementing flexible endoscopic evaluation of swallow (FEES) screening during annual cancer surveillance visits to monitor late‐stage swallowing function. Methods: Patients >2 years post treatment who attended routine oncological visits underwent FEES screening. Feasibility (service data, stakeholder survey) and swallowing outcomes (oral intake, secretions, internal lymphedema, penetration–aspiration, and residue) were collected. Results: Screening was completed with 70% (50/71) of eligible patients. Medical staff and speech‐language pathologists indicated the protocol was worthwhile and achievable to incorporate into practice. Almost all patients were willing to complete the protocol annually. FEES outcomes identified 84% with dysphagia versus only 26% self‐reported dysphagia. Conclusion: Findings indicate FEES screening incorporated into annual oncological reviews is feasible and effective at monitoring late‐stage swallowing function following HNC. [ABSTRACT FROM AUTHOR]

Background: Knowledge of the prognostic factors and performance of machine learning predictive models for 2‐year cancer‐specific survival (CSS) is limited in the head and neck cancer (HNC) population. Methods: Data from our facilities' oncology information system (OIS) collected for routine practice (OIS dataset, n = 430 patients) and research purposes (research dataset, n = 529 patients) were extracted on adults diagnosed between 2000 and 2017 with squamous cell carcinoma of the head and neck. Results: Machine learning demonstrated excellent performance (area under the curve, AUC) in the whole cohort (AUC = 0.97, research dataset), larynx cohort (AUC = 0.98, both datasets), and oropharynx cohort (AUC = 0.99, both datasets). Tumor site and T classification were identified as predictors of 2‐year CSS in both datasets. Hypothyroidism and fitness for operation were further identified in the research dataset. Conclusions: Datasets extracted from an OIS for routine clinical practice and research purposes demonstrated high utility for informing 2‐year head and neck CSS. [ABSTRACT FROM AUTHOR]

Body composition measurement using diagnostic computed tomography (CT) scans has emerged as a method to assess sarcopenia (low muscle mass) in oncology patients. Assessment of skeletal muscle mass (SMM) using the cross-sectional area of a single vertebral slice (at lumbar L3) in a CT scan is correlated with whole-body skeletal muscle volume. This method is used to assess CT-defined sarcopenia in patients with cancer, with low SMM effecting outcomes. However, as diagnostic scans are based on tumour location, not all include L3. We evaluated the evidence for the use of alternate vertebral CT slices for SMM evaluation when L3 is not available. Five electronic databases were searched from January 1996 to April 2020 for studies using CT scan vertebral slices above L3 for SM measurement in adults with cancer (solid tumours). Validation with whole-body SMM, rationale for the chosen slice and sarcopenia cut-off values were investigated. Thirty-two studies were included, all retrospective and cross-sectional in design. Cervical, thoracic and lumbar slices were used (from C3 to L1), with no validation of whole-body SMM using CT scans. Alternate slices were used in lung, and head and neck cancer patients. Sarcopenia cut-off values were reported in 75 % of studies, with differing methods, with or without sex-specific values, and a lack of consensus. Current evidence is inadequate to provide definitive recommendations for alternate vertebral slice use for SMM evaluation in cancer patients. Variation in sarcopenia cut-offs warrants more robust investigation, in order for risk stratification to be applied to all patients with cancer. [ABSTRACT FROM AUTHOR]

Critical weight loss (CWL) continues to be a major issue in head and neck cancer (HNC) and many patients require tube feeding. We investigated the use of reactive feeding tubes (RFTs), associated CWL, and the impact on cancer-specific survival (CSS). A single-institution, retrospective audit was conducted on 460 adult HNC patients who received radiotherapy ± chemotherapy between 2005 and 2017. CSS in patients with CWL and RFTs was compared to those with no tube. Prediction analysis for RFT insertion was also performed. CWL occurred in 53% of patients, and in 88% of those with a RFT (p < 0.001). In patients with CWL, those with a RFT had worse 5 and 10-year CSS compared to those with no tube (68% and 65% vs 83% and 80% respectively, p = 0.040) in multivariate Cox regression analysis. Concurrent chemoradiotherapy combined with CWL was the strongest predictor for RFT insertion (p = 0.003). CWL, combined with having a RFT, impacts negatively on CSS. CWL may be one of the triggers for RFT insertion, however those with no tube have better CSS. This may be due to higher weight loss levels seen in those who have a RFT, and earlier insertion to prevent such losses seems indicated. [ABSTRACT FROM AUTHOR]

Purpose: Following head and neck cancer (HNC) treatment, individuals experience an array of side effects which can impact on physical, emotional, and practical aspects of their lives. Responsive, supportive rehabilitation services are therefore essential to address ongoing survivorship needs. This study examined the nature of patient-reported goals from acute to long-term post-treatment, to inform design/delivery of future rehabilitation services.Methods: Using a cross-sectional cohort design, 91 patients between 2 weeks and 5 years of post non-surgical HNC treatment (acute n = 29; sub-acute n = 28; long-term n = 34), provided their top four rehabilitation goals considering any aspect of their lives. Content analysis was used to categorise responses at each time point.Results: Three core categories of patient goals were identified relating to: (1) treatment side effects (TSE), (2) overall health (OH), and (3) living life (LL). TSE goals were a priority during the acute and sub-acute phases, with less focus long-term. LL goals were prevalent across all time points, though increased in the long-term. Approximately a third of all goals at each time point related to OH.Conclusions: A variety of rehabilitation goals were identified, and the focus shifted over time. These data highlight the importance of changing the focus of rehabilitation as patients' priorities vary over time. Early multidisciplinary care from allied health services is crucial to provide support with managing side effects and returning to daily activities. In the long-term, greater input from services to address health, nutrition, leisure, and fitness goals may be more beneficial. [ABSTRACT FROM AUTHOR]
