Impact of sarcopenia on survival and late toxicity in head and neck cancer patients treated with radiotherapy.

This study aims to determine the impact of sarcopenia on survival and late toxicity in a large cohort of head and neck squamous cell carcinoma (HNSCC) patients treated with definitive (chemo)radiotherapy ((C)RT). MATERIALS AND METHODS: HNSCC patients treated with definitive (C)RT from January 2007 to June 2016 were included. Sarcopenia was assessed from radiation planning computed tomography (CT) scans using skeletal muscles at level C3. The impact of sarcopenia on overall survival (OS) and disease-free survival (DFS) was evaluated using the Kaplan-Meier method. Multivariable association models were developed to assess the impact of sarcopenia on late toxicity. RESULTS: The study population was composed of 750 HNSCC patients. Cut-off values for sarcopenia were set at SMI

ConclusionThe proposed multiparametric MRI-based SLICs+MTh method performs noninvasive assessment of NACT response in osteosarcoma that may improve cancer treatment monitoring, planning, and overall prognosis.Key Points• The simple linear iterative clustering supervoxels and Otsu multithresholding-based technique (SLICs+MTh) successfully estimates the proportion of necrosis, viable tumor, and edema in osteosarcoma in the course of chemotherapy.• The proposed technique is noninvasive and uses multiparametric MRI to measure necrosis as an indication of anticancer treatment response.• SLICs+MTh-based necrosis w...

ConclusionsThe e-ASPECTS software generates robust values for e-ASPECTS and acute infarct volumes when using ST ≤ 4 mm with ST = 1 mm yielding the best performance for predicting baseline stroke severity and clinical outcome after 90 days.Key Points•Clinical utility of automatically derived ASPECTS from computed tomography scans was shown in patients with acute ischemic stroke and treatment with mechanical thrombectomy.•Thin slices (=  1 mm) had the highest clinical utility in comparison with thicker slices (2–10 mm) by having the strongest correlation...

Abstract BACKGROUND AND PURPOSE: Bilateral elective nodal irradiation (ENI) remains the standard treatment for head and neck squamous cell carcinoma (HNSCC). Unilateral ENI could reduce treatment toxicity and improve health-related quality-of-life (HRQOL). This prospective proof-of-principle trial (NCT02572661) investigated the feasibility, safety and clinical benefits of SPECT/CT-guided ENI of the node-negative contralateral neck. MATERIALS AND METHODS: Patients with lateralized T1-3N0-2bM0 HNSCC of the oropharynx, oral cavity, larynx and hypopharynx underwent SPECT/CT after peritumoral 99mTc-nanocolloid inj...

In the modern era, favorable oncologic and survival outcomes are achieved for many patients with head and neck squamous cell carcinoma (HNSCC) treated with curative-intent radiotherapy (RT) [1 –3], particularly for those with human papilloma virus (HPV) associated disease [4,5]. Consequently, there is now substantial emphasis on reduction of late radiation toxicities for the ever increasing numbers of long-term survivors [5]. As burden of xerostomia is partially mitigated by the use of more conformal treatment techniques such as intensity modulated radiotherapy (IMRT) and proton therapy [6–8], dysphagia has ove...

(NRG Oncology) A pooled analysis of data from NRG Oncology studies RTOG 0129 and 0522 compared intensity-modulated radiotherapy (IMRT) with three-dimensional conformal radiotherapy for patients treated for locally advanced head and neck squamous cell carcinoma. The study found that IMRT was associated with significantly reduced xerostomia and feeding tube dependency after treatment, especially in oropharyngeal cancer patients.
