Radiation therapy is a common treatment for head and neck cancers. However, because of the presence of nerve structures (brain stem, spinal cord, and brachial plexus), salivary glands (SGs), mucous membranes, and swallowing muscles in the head and neck regions, radiotherapy inevitably causes damage to these normal tissues. Among them, SG injury is a serious adverse event, and its clinical manifestations include changes in taste, difficulty chewing and swallowing, oral infections, and dental caries. These clinical symptoms seriously reduce a patient’s quality of life. Therefore, it is important to clarify the mechanism of SG injury caused by radiotherapy. Although the mechanism of radiation-induced SG injury has not yet been determined, recent studies have shown that the mechanisms of calcium signaling, microvascular injury, cellular senescence, and apoptosis are closely related to oxidative stress. In this article, we review the mechanism by which radiotherapy causes oxidative stress and damages the SGs. In addition, we discuss effective methods to prevent and treat radiation-induced SG damage.

In addition to anti-tumor effects, ionizing radiation causes damage in normal tissues located in the radiation portals. Oral complications of radiotherapy in the head and neck region are the result of the deleterious effects of radiation on, e.g., salivary glands, oral mucosa, bone, dentition, masticatory musculature, and temporomandibular joints. The clinical consequences of radiotherapy include mucositis, hyposalivation, taste loss, osteoradionecrosis, radiation caries, and trismus. Mucositis and taste loss are reversible consequences that usually subside early post-irradiation, while hyposalivation is normally irreversible. Furthermore, the risk of developing radiation caries and osteoradionecrosis is a life-long threat. All these consequences form a heavy burden for the patients and have a tremendous impact on their quality of life during and after radiotherapy. In this review, the radiation-induced changes in healthy oral tissues and the resulting clinical consequences are discussed.

Radiation Beams

: More than half of cancer patients need radiotherapy during the course of their treatment. Despite the beneficial aspects, the destructive effects of radiation beams on normal tissues lead to oxidative stress, inflammation, and cell injury. Kidneys are affected during radiotherapy of abdominal malignancies. Radiation nephropathy eventually leads to the release of factors triggering systemic inflammation. Currently, there is no proven prophylactic or therapeutic intervention for the management of radiation-induced nephropathy. This article reviews the biomarkers involved in the pathophysiology of radiation-induced nephropathy and its underlying molecular mechanisms. The efficacy of compounds with potential radio-protective properties on amelioration of inflammation and oxidative stress is also discussed. By outlining the approaches for preventing and treating this critical side effect, we evaluate the potential treatment of radiation-induced nephropathy. Available preclinical and clinical studies on these compounds are also scrutinized.

AbstractOral mucositis is an unavoidable side effect of radiation therapy to the head and neck, which can compromise patient health and quality of life. This study investigates the effect of manuka honey on the extent of oral mucositis in head and neck patients in New Zealand. A total of 28 patients were recruited; 10 patients received standard care and 18 patients were given additional manuka honey. Honey was used three times a day; assessment included: extent of oral mucositis using a multi-site mucositis scoring system, weight and quality of life. The first six patients, randomised to the honey arm, used undiluted honey and pulled out in the first week because of extreme nausea, vomiting and stinging sensations in the mouth. The next 12 honey patients used a honey mouthwash (diluted 1:3). Six of these patients completed the trial and four more completed the first 4 weeks of the trial. Eight control patients completed the trial. In contrast to previous honey trials in Malaysia, Egypt, Iran and India, diluted manuka honey did not decrease the extent and onset of radiation-induced oral mucositis but did appear to ameliorate radiation-induced weight loss and increase quality of life in the absence of cisplatin chemotherapy.

Radiation induced xerostomia is a persistent clinical presentation that affects the quality of life in head and neck cancer patients even with the best of the intensity modulated radiotherapy protocols. Comprehensive review of the anatomic, histologic, developmental and neuronal entities of salivary glands from a regenerative perspective, ensuing radiation is taken. It also evaluates the systemic and glandular radiation responses that form the early and late clinical changes. From these, the article submits probable strategies; based on the current knowledge and future challenges involved, in reversing radiation induced xerostomia. Further, it elaborates on the status of radioprotectors and mitigators including the recently reported biologic and chemical derivatives and proposes the rationale of using combination radioprotector therapy in radiation injuries. A brief of palliative regimes, alternate treatment modes and technologic advancements in radiotherapy are also explained. Salivary gland histologic components, which need to be protected in the emerging radiotherapy protocols and can be targeted in different salivary gland regeneration therapies is highlighted. The paper contributes to an improved understanding in radiation induced xerostomia and deliberates on novel mechanisms towards enhancing quality of life in head and neck cancer radiotherapy patients.

The Impact

Purpose To investigate the impact of treatment-related toxicity on health-related quality of life (HRQoL) among patients with head and neck squamous cell carcinoma treated with radiotherapy either alone or in combination with chemotherapy or surgery. Patients and Methods The study sample was composed of 425 disease-free patients. Toxicity was scored according to the European Organisation for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) late radiation-induced morbidity scoring system. HRQoL was assessed using the EORTC Quality of Life Questionnaire C30. These assessments took place at 6, 12, 18, and 24 months after completion of radiotherapy. The analysis was performed using a multivariate analysis of variance. Results Of the six RTOG scales investigated, two significantly affected self-reported HRQoL, salivary gland (RTOGxerostomia) and esophagus/pharynx (RTOGswallowing). Although RTOGxerostomia was reported most frequently, HRQoL was most affected by RTOGswallowing, particularly in the first 18 months after completion of radiotherapy. Conclusion Late radiation-induced toxicity, particularly RTOGswallowing and RTOGxerostomia, has a significant impact on the more general dimensions of HRQoL. These findings suggest that the development of new radiation-induced delivery techniques should not only focus on reduction of the dose to the salivary glands, but also on anatomic structures that are involved in swallowing.

Abstract Objective: Childhood-onset craniopharyngiomas (CP) are diagnosed due to clinical symptoms (symCP) or incidentally (incCP). We investigated clinical manifestations and outcome in incCPs and symCPs. Design and methods: IncCP were discovered in 4 (3m/1f) and symCP in 214 CP (101m/113f) recruited 2007–2014 in KRANIOPHARYNGEOM 2007. Age, sex, height, body mass index (BMI), tumor size, degree of resection, pre- and postsurgical hypothalamic involvement/lesions, pituitary function and outcome were compared between both subgroups. Results: Reasons for imaging in incCP were cerebral palsy, head trauma, nasal obstruction, and tethered-cord syndrome, whereas headache (44%) visual impairment (25%), and growth retardation (17%) lead to imaging in symCP. Tumor size at diagnosis was smaller in incCP (median tumour size 3.26 cm2; range: 0.56–5.13 cm2) when compared with symCP (median tumour size 12.16 cm2; range: 0.004–79.54 cm2). Age, gender, BMI, height, hydrocephalus, tumor location, and hypothalamic involvement at diagnosis of incCP were within the range of these parameters in symCP. Complete resections were achieved more frequently (3/4 patients) in incCP when compared with symCP (20%). Surgical hypothalamic lesions were distributed similar in incCP and symCP. Irradiation was performed only in symCP (33%). No noticeable differences were observed concerning survival rates, endocrine deficiencies, BMI, height, functional capacity and quality of life of the 4 incCP cases when compared with the symCP cohort. Conclusions: IncCP are rare (1.8%) and characterized by lack of endocrine deficiencies, resulting in normal height and BMI, no hydrocephalus, and smaller tumor size at diagnosis when compared with symCPs. Outcome of the observed incCP is similar with symCP.

e17514 Background: Malignant pelvic tumors account for more than 25% of cancer incidence in Russia. Radiation therapy is the most common treatment for such patients; however, 10-15% of patients develop radiation-induced complications of the pelvic organs, and more effective treatments are required to manage these complications. Methods: The study included 30 patients with cervical cancer T3NхM0 after combination treatment. 7-10 months after combined radiation treatment (total radiation dose to the primary focus 80 Gy), patients developed erosive ulcerative radiation rectitis (RTOG grade 1 and 2). Patients were divided into 2 groups: main group (n = 15) – conservative treatment combined with LILEDR. Each course included 10 LILEDR sessions, the red spectrum λ = 640 nm on the cubital vein projection (exposure time 5 minutes, dose 6.86 J/cm2) and locally on the ulcerated zones (exposure time 3 minutes, dose 3.96 J/cm2). Patients received 2 LILEDR courses with a 1-month interval. The control group received only conservative therapy. Results: Main clinical manifestations of rectitis (tenesmus, bloody mucous discharge) disappeared in the main group already on the 3-4th day of the first course, epithelialization of ulcerative defects occurred in a shorter period of 7-10 days. Soft superficial scars not causing rectal stenosis formed at the site of the ulcer by the end of LILEDR courses. The control group showed long periods of the ulcer epithelialization up to 30 days, late remission and a lingering recurrent character of the disease. Conclusions: LILEDR in combination with the main conservative therapy allows rapid managing with the clinical symptoms of radiation rectitis and regression of disorders developed after the complex treatment, which improves the quality of life of patients and shortens the rehabilitation period.
