Imitation Learning with Superhuman Policy Gradient Optimization for Sequential Cancer Treatment Decisions
… framework for sequential deci- sion making in head and neck cancer (HNC) treatment. Our method, Superhu- man Policy Gradient Optimization (SPGO), integrates inverse reinforcement learning principles with policy gradient updates to derive three-stage treat- ment policies directly from recorded …

A demographic review of stage of presentation and survival rates of head and neck cancer patients in the Western Cape, South Africa
… poorer access to healthcare, more advanced cancers, and worse survival in rural and remote populations. This study investigates if significant disparities exist with regard to stage at presentation and overall survival of patients with head and neck cancer (HNC) between geographical areas …

Penalized maximum likelihood method for reducing limited-angle artifacts in image reconstructions for a dual-panel high-spatial-resolution pet system
… has limited spatial resolution for imaging human head and neck cancer (HNC) due to the small size of lymph nodes. We are developing a dual-panel high-spatial-resolution PET system for better imaging HNC. The PET system is designed as a dual-panel geometry to consider the patient’s comfort, but the …

Deep Learning and Radiomics Based Outcome Prediction for Cancer Patients
The accurate prediction of cancer patient treatment outcomes is essential for personalized treatment planning and improved treatment outcome. The use of machine learning methods, such as deep learning (DL) and radiomics, has been gaining attention in the field of cancer research for predicting …

Design study of a two-panel head-and-neck cancer dedicated position emission tomography system
Head and neck cancer (HNC) is collectively a group of cancers that usually begin in mucosal surfaces inside the head and neck. Due to the complex anatomy and vital physiological role of the tumor-involved regions, the goal of HNC treatment is not only to improve survival outcomes but also to …

A Systems Approach to Modelling Tumour and Tissue Response in Radiotherapy for Head-and-Neck Cancer
… to radiotherapy poses significant challenges in head-and-neck cancer (HNC), with outcomes ranging from severe toxicities to loco-regional recurrence (LRR). Multi-modal biomarker data—encompassing genetic, dosimetric, and imaging domains—offers an opportunity to address this variability by …

Quantifying, Understanding and Predicting Differences Between Planned and Delivered Dose to Organs at Risk in Head & Neck Cancer Patients Undergoing Radical Radiotherapy to Promote Intelligently Targeted Adaptive Radiotherapy
… (RT) is an effective but toxic treatment for head and neck cancer (HNC). Contemporary radiotherapy techniques sculpt dose to target disease and avoid organs at risk (OARs), but anatomical change during treatment mean that the radiation dose delivered to the patient – delivered dose (DA), is …

Ai-Enabled Online Plan Adaptation For Mr-Guided Stereotactic Ablative Radiotherapy (Sabr) of Head and Neck Cancer
<p>Head and neck cancer (HNC) is a prevalent cancer type worldwide. Stereotactic ablative radiotherapy (SABR) has emerged as an effective treatment for HNC, delivering highly conformal doses to the tumor target while sparing surrounding normal tissues with a sharp dose gradient. However, the …

Methods for the Prediction of Osteoradionecrosis resulting from Head and Neck Cancer Radiation Therapy
<p>Head and neck cancer (HNC) is the sixth most diagnosed cancer worldwide with over 600,000 patients diagnosed every year. One of the primary methods to treat HNC is through radiation therapy (RT). While RT is effective at treating HNC, late toxicities resulting from treatment can occur months to …

Illness Perceptions, Coping, and Psychological Outcomes in Patients with Head and Neck Cancer and their Caregivers
Patients with head and neck cancer (HNC) often experience enduring impairments in functional ability and appearance as a consequence of their disease. Despite high rates of psychological distress and low levels of health-related quality of life (HRQL) reported by this population and their …

Complicaciones respiratorias en pacientes intervenidos por cáncer de cavidad oral, faringe y laringe en La Rioja
Introduction Cancer is one of the leading causes of morbidity and mortality worldwide. In recent years, survival rates for cancer have increased; however, this is not the case for head and neck cancers (HNC). HNC is the seventh most common cancer globally, and its incidence is estimated to increase …

Integration of Biomedical Imaging and Translational Approaches For Management of Head and Neck Cancer
… with radiotherapy (RT) platforms for monitoring and adaptation of radiation dose, prediction of tumor response and disease outcomes, and characterization of patterns of failure and normal tissue toxicity in head and neck cancer (HNC) patients with potentially curable tumors. In Aim 1, we showed …

Design study of an organ-dedicated positron emission tomography system
… tomography (PET) has been widely used for cancer diagnosis and treatment, but its low spatial resolution limits the management of cancers in specific organs or regions. To promote the pre-clinical and clinical research and improve the diagnosis accuracy and treatment out- comes, …

Acute Pain Prediction in Oral Cavity and Oropharyngeal Cancer Patients Receiving Radiation Therapy
<p>Oral-Cavity and oropharyngeal cancers (OC/OPC) are types of head and neck cancers that are increasing in incidence domestically. Radiation therapy (RT) is crucial in OC/OPC management. Pain is a common and challenging symptom for most patients during therapy, as nearly all patients undergoing …

Novel image processing and deep learning methods for head and neck cancer delineation from MRI data
… treatment aims to achieve accurate treatment of cancer without introducing damage and side effects to organs at risk (OAR). Development of medical imaging technique enables molecular study of cancer to provide quantitative analysis and three-dimensional visualisation to oncologists and …

Vegetable intake and head and neck cancer
Introduction: Head and neck cancer (HNC), especially cancers of the oral cavity, oropharynx, hypopharynx, and larynx is the sixth most common cancer, affecting more than half a million patients worldwide and approximately 4% of patients in the United States, with a five-year survival rate of 60% …

The SYNQ study: SYmptoms, Nutrition, and Quality of life in head and neck cancer survivors
At least 90% of head and neck cancer (HNC) survivors experience significant symptom burden that impacts their ability and/or desire to eat as a result of tumor location, treatment with chemoradiation and/or surgical resection of the tumor. Symptoms prevalent in this population that may persist long …
