RADIATION DYSPHAGIA

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Malnutrition has been found to have negative effects on the immune system and inflammatory responses, impairing the wound healing process. Free flap failure is a serious complication in patients undergoing microvascular reconstruction, as it increases patient morbidity, length of stay in the hospital, patient, and hospital costs, as well as causes the need for further surgical interventions1 . Malnutrition is estimated to be present in 35-50% of head and neck cancer patients with higher rates in those experiencing hypo-oropharyngeal disease...

Trismus commonly arises after surgery for head and neck cancer (HNC) and its severity is potentiated by postoperative radiotherapy. While the benefit of trismus rehabilitation after surgery and radiotherapy is well established, the evidence during radiotherapy is less clear. This may be due to poor adherence to trismus exercises secondary to acute mucositis. This study assessed the feasibility of using a novel trismus device during adjuvant radiotherapy for HNC in patients with acute postoperative trismus. Prospective single-arm cohort feasibility study...

AIMS: Prehabilitation is a process of identifying and assessing factors that could compromise the physical and psychological health of patients undergoing cancer treatment and implementing an intervention to combat such concerns. The use of prehabilitation in cancer surgery has yielded positive outcomes in rectal, lung and abdominal cancers. Prehabilitation strategies have potential to improve the management of patients receiving radiation therapy or chemoradiation. The aim of the present study was to map the evidence of the assessment and evaluation of prehabilitation for radiation therapy patients...

Oesophageal squamous cell carcinoma is a common malignancy worldwide. Definitive chemoradiotherapy is the standard treatment for patients with resectable stage oesophageal squamous cell carcinoma who cannot undergo surgery, as well as those with locally advanced unresectable oesophageal squamous cell carcinoma. However, it has several disadvantages such as poor survival, radiation-related toxicities and severe and lethal complications related to salvage treatment for residual or recurrent disease. Numerous clinical trials on chemoradiotherapy have been conducted to confirm the optimal combination of irradiation and chemotherapy...

OBJECTIVES: To evaluate participant-reported atypical dysphagia symptoms and their association with oxaliplatin treatment. METHODS: This observational study recruited 73 adults with solid tumours outside the head, neck or upper gastrointestinal tract. All had dysphagia, were in hospital or hospice and were treated by Medical Oncology, Radiation Oncology or Palliative Care. Participants reported their experiences of swallowing difficulties by semistructured interview...

A 76-year-old woman with a history of rheumatoid arthritis, Sjögren syndrome, and hypertension presented with a headache, fever, and dysphagia. The patient was taking prednisone and leflunomide to treat rheumatoid arthritis. Her headache was primarily left sided and occasionally radiated to the occipital region. The patient had a high-grade fever spike, with a temperature of 104°F (40°C). Results of a prior lumbar puncture and temporal artery biopsy from an outside hospital were negative. Findings of a neurologic examination were unremarkable...

PURPOSE: Our purpose was to compare robust intensity modulated proton therapy (IMPT) plans, automatically generated with wish-list-based multicriterial optimization as implemented in Erasmus-iCycle, with manually created robust clinical IMPT plans for patients with head and neck cancer. METHODS AND MATERIALS: Thirty-three patients with head and neck cancer were retrospectively included. All patients were previously treated with a manually created IMPT plan with 7000 cGy dose prescription to the primary tumor (clinical target volume [CTV]7000) and 5425 cGy dose prescription to the bilateral elective volumes (CTV5425)...

Modified Barium Swallow Studies (MBSS) are a critical part of the evaluation, treatment planning, and outcome assessment for persons with swallowing disorders. Since MBSSs use ionizing radiation with associated cancer risks, many clinicians have reduced radiation exposure by reducing the fluoroscopic pulse rate. However, by reducing pulse rate, we also decrease the temporal resolution of MBSSs which has been shown in pilot studies to significantly reduce diagnostic accuracy. Two hundred MBSSs from patients routinely undergoing MBSS as standard of care conducted at 30 pulses per second (pps) using the Modified Barium Swallow Study Impairment Profile (MBSImP™) standardized administration protocol were selected...

PURPOSE: Knowledge-based planning (KBP) has evolved to standardize and expedite the complex process of radiation therapy planning for nasopharyngeal cancer (NPC). Herein, we aim to develop and validate the suitability of a single-optimization KBP for NPC. METHODS AND MATERIALS: Volumetric modulated arc therapy plans of 103 patients with NPC treated between 2016 and 2020 were reviewed and used to generate a KBP model. A validation set of 15 patients was employed to compare the quality of single optimization KBP and clinical plans using the paired t test and the Wilcoxon signed rank test...

Identification of the optimal treatment strategy is challenging in elderly with localized non-small cell lung cancer (NSCLC). Concurrent chemotherapy with low-dose cisplatin represents an option for elderly. Outcomes (1) in elderly (≥70 years, n = 158) vs. younger patients ( n = 188) and (2), independently of age, in definitive radiochemotherapy, with low-dose cisplatin ( n = 125) vs. cisplatin/vinorelbine ( n = 76) were studied. Elderly included more males, had a lower Karnofsky index, more comorbidities, and lower stages...

OBJECTIVES: Patients on anticancer therapy attending palliative care services often have oral health problems, but not enough is known in this regard (in India). This cross-sectional study aimed to elucidate this issue. METHODS: Participants were 98 patients with metastatic cancer (52 males, 46 females) who attended the palliative care clinic and were assessed by a multidisciplinary team consisting of dental health professionals working alongside the palliative care team, between August 2021 and October 2022...

Esophageal squamous cell carcinoma (ESCC) often presents with debilitating dysphagia, significantly affecting quality of life. In metastatic disease, standard therapy with radiation and chemotherapy is associated with high morbidity. Liquid nitrogen cryotherapy offers a minimally invasive intervention for palliation in metastatic esophageal cancers. Although beneficial outcomes have been reported in esophageal adenocarcinoma, few studies have assessed its safety and efficacy as palliation treatment in metastatic ESCC...

PURPOSE: The study aims to enhance the efficiency and accuracy of literature reviews on normal tissue complication probability (NTCP) in head and neck cancer patients using radiation therapy. It employs meta-analysis (MA) and natural language processing (NLP). MATERIAL AND METHODS: The study consists of two parts. First, it employs MA to assess NTCP models for xerostomia, dysphagia, and mucositis after radiation therapy, using Python 3.10.5 for statistical analysis...

PURPOSE: Head and neck cancers (HNCs) are the third most commonly treated cancer with radiation in Ethiopia. Most patients present with advanced stage and are not candidates for curative treatment. The objective of our study is to assess the outcome of hypofractionated palliative radiotherapy (RT) for advanced HNCs in a resource-limited setting. MATERIALS AND METHODS: Patients with histology-proven advanced HNC candidates for hypofractionated palliative RT were enrolled...

Well-differentiated thyroid carcinoma has a favorable prognosis with a 5-year survival rate of over 95%. However, the undifferentiated or anaplastic type accounting for < 0.2%, usually in elderly individuals, exhibits a dismal prognosis with rapid growth and disappointing outcomes. It is the most aggressive form of thyroid carcinoma, with a median survival of 5 mo and poor quality of life (airway obstruction, dysphagia, hoarseness, persistent pain). Early diagnosis and staging are crucial. Diagnostic tools include biopsy (fine needle aspiration, core needle, open surgery), high-resolution ultrasound, computed tomography, magnetic resonance imaging, [(18)F]fluoro-D-glucose positron emission tomo-graphy/computed tomography, liquid biopsy and microRNAs...

A 71-year-old female presented with progressive dysphagia and unexplained weight loss. Computed tomography and esophagogastroduodenoscopy (EGD) revealed invasive esophageal squamous cell carcinoma, which was initially treated with local radiation and esophageal stenting. Over the next year, the patient experienced multiple symptoms and hospital admissions consistent with a malignant tracheoesophageal fistula, despite negative findings on imaging, bronchoscopy, and EGD. Prophylactic antibiotics were initiated based on symptomatology to prevent septic episodes...

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...

Extra-nodal NK/T cell lymphoma, nasal type (ENKTL) is a rare and aggressive non-Hodgkin lymphoma primarily seen in Asian and South American populations. Diagnosis involves methods like biopsy and molecular testing, with treatment typically combining systemic and radiation therapy. We present the rare case of a 62-year-old female who was diagnosed with localized ENKTL upon initial presentation of nasal congestion. She was started on radiation therapy and responded favorably at first, with decreased congestion and facial swelling...

Despite advances in head and neck cancer treatment, virtually all patients experience chemoradiation-induced toxicities. Oral mucositis (OM) and dysphagia are among the most prevalent and have a systemic impact on patients, hampering treatment outcome and harming quality of life. Accurate prediction of severe cases is crucial for improving management strategies and, ultimately, patient outcomes. This scoping review comprehensively maps the reported predictors and critically evaluates the performance, methodology, and reporting of predictive models for these conditions...

BACKGROUND: Although dysphagia is a common side effect after radiotherapy (RT) of head and neck cancer (HNC), data on long-term dysphagia is scarce. We aimed to 1) compare radiation dose parameters in HNC survivors with and without dysphagia, 2) investigate factors associated with long-term dysphagia and its possible impact on health-related quality of life (HRQoL), and 3) investigate how our data agree with existing NTCP models. METHODS: This cross-sectional study conducted in 2018-2020, included HNC survivors treated in 2007-2013...
