head neck radiotherapy

Way Chiang, Zofia Tynski
Angiosarcoma is a rare vascular soft tissue tumor of endothelial origin most commonly seen in the elderly as a primary cutaneous head and neck malignancy. Furthermore, a peritoneal angiosarcoma is an exceedingly rare entity. This is the second case of primary peritoneal angiosarcoma reported in literature that is not associated with prior radiotherapy. Herein, we describe a case of primary peritoneal angiosarcoma metastatic to both the liver and bone in a male patient with metachronous renal cell carcinoma and parathyroid adenoma...

Osteonecrosis of the jaw (ONJ) is an increasingly common condition primarily due to the rise of medication related osteonecrosis of the jaw (MRONJ) and osteoradionecrosis (ORN). Apart from MRONJ and ORN there remains a wide and varied range of rare causes and diseases that can lead to a clinical presentation of ONJ. This article aims to highlight alternatives causes of jaw necrosis following review of the literature to aid diagnosis and treatment planning for dental and head and neck specialities.

BACKGROUND AND PURPOSE: Accelerated repopulation (AR) can compromise tumor control after conventional radiotherapy for fast-growing tumors. Standard AR models assume it begins at a fixed time, with repopulation rates independent of the number of clonogens killed. We investigate the validity and significance of an alternative model where onset-time and rate of AR depend on the number of clonogens killed, and thus on dose and dose-fractionation. MATERIALS AND METHODS: We analyzed tumor control (TCP) from randomized trials for head and neck cancer (HNC, 7283 patients), featuring wide ranges of doses, times, and fractionation-schemes...

OBJECTIVE: This case-control study aimed to evaluate the effects of conventional radiotherapy (RT) on the prevalence and populations of oral microorganisms in head and neck cancer patients who did not receive adequate preventive dental care. It was hypothesized that side effects of radiotherapy could be associated with radiation dose, microbiological aspects, and socioeconomic conditions of the patients. DESIGN: Twenty-eight dentate patients with head and neck cancer submitted to RT were included in the study...

BACKGROUND: Cancer patients frequently suffer from physical and psychosocial impairments due to their disease and its treatment. Psychooncology (PO) can help to cope with stress resulting from outpatient radiotherapy (RT) treatment. There are currently few data regarding patients' wishes for PO support. The aim of this study was to investigate the number of patients with a wish for PO, treatment paths, and predictors of the wish for PO among cancer patients at the beginning of RT. METHODS: The results of routine psychological stress screening (Hornheide screening instrument; cut-off  ≥ 4) of 944 cancer patients between 2015 and 2017 were analyzed in a retrospective cross-sectional study...

Surgery, radiation therapy and chemotherapy are the oldest modalities for cancer treatment. However, as part of a continuous research in medicine, in order to improve therapeutic precision and biological effectiveness, there is an increasing interest into the use of heavy particle (e.g. protons or heavy ions) in the treatment of solid tumors. However, the restricted availability of the technology has concentrated the expertise in highly specialized centers that take care and treat extreme cases and rare pathologies...

Overall radiation treatment time has long been recognized as an important factor in head and neck tumor control. The concern of tumor growth in waiting time either before starting radiotherapy or during treatment is substantial given its negative impact on clinical outcome. There is an overwhelming evidence that increasing the time to initiate treatment increases the tumor burden and worsens the prognosis. This effect is more pronounced especially in patients with an early stage cancer disease. Delay in treatment initiation is contributed by both health care- and patient-related factors...

Our aim was to compare the efficacy of the Therabite® jaw motion rehabilitation system (Atos Medical) with that of wooden spatulas to relieve and prevent trismus in patients who have had radiotherapy for stage three and four oral and oropharyngeal cancer. Secondary aims were to assess the feasibility and the impact of exercise on health-related quality of life (QoL), and the use of health services after treatment. We designed a randomised, open-label, controlled, three-centre feasibility study to compare the effectiveness and cost of the Therabite® and wooden spatulas...

Radiation oncologists are increasingly tasked with the management of elderly patients with non-melanoma skin cancer, unsuitable for surgical intervention due to inoperable lesions and/or poor performance status. In this cohort, hypofractionated radiotherapy, delivered either daily, alternative daily or once weekly is highly effective. A systematic literature search was conducted of PUBMED, MEDLINE and EMBASE databases using the algorithm ('radiotherapy' OR 'radiation therapy' OR 'brachytherapy') AND ('hypofraction' OR 'hypofractionated' OR 'hypofractionation') AND ('skin neoplasms' OR 'carcinoma' OR 'malignancy') AND ('skin' OR 'epidermis' OR 'epidermal' OR 'cutaneous')...

OBJECTIVES: Prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) is used for detection and (re)staging of prostate cancer. However, healthy salivary, seromucous, and lacrimal glands also have high PSMA-ligand uptake. This study aimed to describe physiologic PSMA-ligand uptake distribution characteristics in the head and neck to aid in PSMA PET/CT interpretation and to identify possible new clinical applications for PSMA-ligand imaging. STUDY DESIGN: Thirty consecutive patients who underwent PSMA PET/CT for prostate cancer were evaluated...

With the UK's first high-energy Proton Beam Therapy Centre set to open next year at Manchester's The Christie, young patients with head and neck tumours, cancers close to the skull or spine, or a variety of soft tissue tumours, and adults with cancers difficult to treat using 'conventional' photon-based radiotherapy will, for the first time, be able to receive NHS proton beam therapy (PBT) without having to travel overseas. HEJ editor, Jonathan Baillie, visited the site of The Christie's new £135 million PBT Centre to find out more about the design and construction of a facility which interserve construction director for the North-West, Phil Shaw, describes as one of the most complex and specialist he has worked on...

Recent theoretical research on spatiobiologically integrated 
 radiotherapy has focused on optimization models that adapt fluence-maps to the 
 evolution of tumor state, for example, cell densities, as observed in quantitative 
 functional images 
 acquired over the treatment course. We propose an optimization 
 model that adapts the length of the treatment course as well as the fluence-maps 
 to such imaged tumor state. Specifically, after observing the tumor cell 
 densities at the beginning of a session, the treatment planner solves a group of convex optimization problems to determine an optimal number of remaining treatment sessions, and a corresponding optimal fluence-map for each of these sessions...
