Abstract
Any conflict in countries that process nuclear power plants raises concerns of the potential radiation injuries to the people in that region and beyond such as the current conflict in Ukraine. International healthcare organizations and societies should prepare for the potential scenarios of nuclear incidents. The Worldwide Network for Blood and Marrow Transplantation (WBMT) and its members, have recent experience preparing for this type of events such as the Fukushima incident in 2011. In this article, we discuss the risks of radiation exposure, current guidelines, and scientific evidence on hematopoietic support, including the role of hematopoietic stem cell transplant (HCT) for those exposed to nuclear radiation, and the role that the WBMT and other global BMT societies can play in triaging and managing people suffering from radiation injuries.

Abstract
INTRODUCTION Neurocognitive impairment from inadvertent brain irradiation is common following intensity-modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC). This study aimed to determine the prevalence, pattern, and radiation dose-toxicity relationship of this late complication. MATERIALS AND METHODS We undertook a cross-sectional study of 190 post-IMRT NPC survivors. Neurocognitive function was screened using the Montreal Cognitive Assessment-Hong Kong (HK-MoCA). Detailed assessments of eight distinct neurocognitive domains were conducted: intellectual capacity (WAIS-IV), attention span (Digit Span and Visual Spatial Span), visual memory (Visual Reproduction Span), verbal memory (Auditory Verbal Learning Test), processing speed (Color Trail Test), executive function (Stroop Test), motor dexterity (Grooved Pegboard Test) and language ability (Verbal Fluency Test). The mean percentiles and Z-scores were compared with normative population data. Associations between radiation dose and brain substructures were explored using multivariable logistic regression. RESULTS The median post-IMRT interval was 7.0 years. The prevalence of impaired HK-MoCA was 25.3 % (48/190). Among the participants, 151 (79.4 %) exhibited impairments in at least one neurocognitive domain. The predominantly impaired domains included verbal memory (short-term: mean Z-score, -0.56, p < 0.001; long-term: mean Z-score, -0.70, p < 0.001), processing speed (basic: mean Z-score, -1.04, p < 0.001; advanced: mean Z-score, -0.38, p < 0.001), executive function (mean Z-score, -1.90, p < 0.001), and motor dexterity (dominant hand: mean Z-score, -0.97, p < 0.001). Radiation dose to the whole brain, hippocampus, and temporal lobe was associated with impairments in executive function, verbal memory, processing speed, and motor dexterity. CONCLUSIONS Neurocognitive impairment is prevalent and profound in post-IMRT NPC survivors. Cognitive assessment and rehabilitation should be considered part of survivorship care.

Abstract
PURPOSE The purpose of the present prospective study was to evaluate the significance of geriatric conditions measured by a comprehensive geriatric assessment (GA) for the prediction of the risk of high-grade acute radiation-induced toxicity. METHODS A total of 314 prostate cancer patients (age ≥ 65 years) undergoing definitive radiotherapy at a tertiary academic center were included. Prior to treatment, patients underwent a GA. High-grade toxicity was defined as acute toxicity grade ≥ 2 according to standard RTOG/EORTC criteria. To analyze the predictive value of the GA, univariable and multivariable logistic regression models were applied. RESULTS A total of 40 patients (12.7%) developed acute toxicity grade ≥ 2; high grade genitourinary was found in 37 patients (11.8%) and rectal toxicity in 8 patients (2.5%), respectively. Multivariable analysis revealed a significant association of comorbidities with overall toxicity grade ≥ 2 (odds ratio [OR] 2.633, 95% confidence interval [CI] 1.260-5.502; p = 0.010) as well as with high-grade genitourinary and rectal toxicity (OR 2.169, 95%CI1.017-4.625; p = 0.045 and OR 7.220, 95%CI 1.227-42.473; p = 0.029, respectively). Furthermore, the Activities of Daily Living score (OR 0.054, 95%CI 0.004-0.651; p = 0.022), social status (OR 0.159, 95%CI 0.028-0.891; p = 0.036), and polypharmacy (OR 4.618, 95%CI 1.045-20.405; p = 0.044) were identified as independent predictors of rectal toxicity grade ≥ 2. CONCLUSION Geriatric conditions seem to be predictive of the development of high-grade radiation-induced toxicity in prostate cancer patients treated with definitive radiotherapy.

Abstract
Health effects of space radiation are a serious concern for astronauts on long-duration missions. The lens of the eye is one of the most radiosensitive tissues in the body and, therefore, ocular health risks for astronauts is a significant concern. Studies in humans and animals indicate that ionizing radiation exposure to the eye produces characteristic lens changes, termed "radiation cataract," that can affect visual function. Animal models of radiation cataractogenesis have previously utilized inbred mouse or rat strains. These studies were essential for determining morphological changes and dose-response relationships between radiation exposure and cataract. However, the relevance of these studies to human radiosensitivity is limited by the narrow phenotypic range of genetically homogeneous animal models. To model radiation cataract in genetically diverse populations, longitudinal cataract phenotyping was nested within a lifetime carcinogenesis study in male and female heterogeneous stock (HS/Npt) mice exposed to 0.4 Gy HZE ions (n = 609) or 3.0 Gy γ-rays (n = 602) and in unirradiated controls (n = 603). Cataractous change was quantified in each eye for up to 2 years using Merriam-Focht grading criteria by dilated slit lamp examination. Virtual Optomotry™ measurement of visual acuity and contrast sensitivity was utilized to assess visual function in a subgroup of mice. Prevalence and severity of posterior lens opacifications were 2.6-fold higher in HZE ion and 2.3-fold higher in γ-ray irradiated mice compared to unirradiated controls. Male mice were at greater risk for spontaneous and radiation associated cataracts. Risk for cataractogenesis was associated with family structure, demonstrating that HS/Npt mice are well-suited to evaluate genetic determinants of ocular radiosensitivity. Last, mice were extensively evaluated for cataract and tumor formation, which revealed an overlap between individual susceptibility to both cancer and cataract.

Abstract
OBJECTIVE Imaging changes after stereotactic radiosurgery (SRS) can occur for years after treatment, although the available data on the incidence of tumor progression and adverse radiation effects (ARE) are generally limited to the first 2 years after treatment. METHODS A single-institution retrospective review was conducted of patients who had >18 months of imaging follow-up available. Patients who had ≥1 metastatic brain lesions treated with Gamma Knife SRS were assessed for the time to radiographic progression. Those with progression ≥18 months after the initial treatment were included in the present study. The lesions that progressed were characterized as either ARE or tumor progression based on the tissue diagnosis or imaging characteristics over time. RESULTS The cumulative incidence of delayed imaging radiographic progression was 35% at 5 years after the initial SRS. The cumulative incidence curves of the time to radiographic progression for lesions determined to be ARE and lesions determined to be tumor progression were not significantly different statistically. The cumulative incidence of delayed ARE and delayed tumor progression was 17% and 16% at 5 years, respectively. Multivariate analysis indicated that the number of metastatic brain lesions present at the initial SRS was the only factor associated with late radiographic progression. CONCLUSIONS The timing of late radiographic progression does not differ between ARE and tumor progression. The number of metastatic brain lesions at the initial SRS is a risk factor for late radiographic progression.

Abstract
OBJECTIVE To compare characteristics and outcomes in patients who had radiotherapy (RT) for prostate cancer (PCa) and underwent urinary diversion (UD) due to prostatic fistula (Fistula) vs localized radiation injury (Localized). METHODS This study was a retrospective single-institution study. Exclusion criteria included follow-up <3 months, large pelvic tumor, and surgery for cancer control. The Fistula group included fistulization outside of the urinary tract (rectal, soft tissue, thigh, pubic symphysis, and extensive necrosis surrounding the prostate). The group Localized had a multitude of problems; however, all were confined to the urinary tract. Patient characteristics, perioperative variables, and outcomes were compared between groups. RESULTS Sixty-nine patients were included and had UD from 2009-2022. Median age and time from RT to UD were 73 (interquartile range (IQR) 67.9, 78.1) and 7.3 (IQR 3.2, 12.5) years. There were 29 (42%) and 40 (58%) patients in the Fistula and Localized groups. The Fistula group had a higher rate of abdominal/perineal approach (62.1% vs 12.5%, P <.001), a lower rate of right colon pouch (17.2% vs 40%, P = .043), and a longer operative time (515.7 vs 414.2 minutes, P = .017). Clavien-Dindo complications ≥3 were higher in the Fistula group (44.8% vs 20%, P = .027), including a higher rate of re-operation for recurrent pelvic abscess (37.9% vs 5%, P <.001). Survival for the cohort was 85.5% and did not differ between groups. CONCLUSION Patients with prostate fistula after RT for PCa undergoing UD had longer, more complex operations, and higher rates of complications, notably post-operative pelvic abscesses, compared to men with localized RT injury. Long-term survival was comparable in both groups.

Abstract
The question about correlation between organic and functional changes in persons, exposed to radiation is still insufficiently studied. Dynamics of morbidity for different forms and classes of non-tumour diseases periodisation, proposed by epidemiologists, suggests the identification of three main periods: «early» (the first 6 post-Chornobyl accident years); «distant» (12-21 years) and «late» (22-30 years). However, the correspondence this periodisation to the results of epidemiological data, without taking into account the clinical features of the diseases, may contribute to the impression, that in the first period after a radiation disaster functional disorders (or autonomic regulation disorders, etc.) prevail in all cases. Meanwhile, the data from ophthalmological and neurological studies, which we aim to demonstrate in this paper, rather indicate the presence of a significant morphological basis for the development of functional disorders in early period after a radiation disaster. The objective of this work is analyse modern experimental, epidemiological and clinical data on the correlation between organic and functional changes, characteristic of radiation cerebro-ophthalmological effects - radiation cataracts, age-related macular degeneration, cerebral small vessel disease, and neurocognitive deficits. Materials and methods. The criteria for inclusion in the analytical review were peer-reviewed publications in PubMed/MEDLINE, Scopus, Web of Science, and manually selected papers; the results of our own research were also used. An additional analysis of the results of examinations conducted in 1991-2004 was performed, which included a total of 11 123 persons irradiated as the result of catastrophy at the Chornobyl NPP. Results. In the first period of radiation cataract development, which is a specific consequence of radiation exposure, morphological changes (lens opacities) are observed, which lead to a decrease in visual function only later. Analysing the correlation between organic and functional changes in the development of diseases, for which ionising radiation exposure is a significant risk factor, we observe a similar picture. For example, CSVD associated with arterial hypertension may be a manifestation of accelerated aging associated with exposure to ionising radiation.Similarly, the initial signs of age-related macular degeneration in radiation-exposed individuals are usually manifested by changes in the morphology of the retina, choroid, and pigment epithelium in the macular area, while functional disorders in the form of decreased central vision and metamorphopsia, etc., occur later.

Abstract
BACKGROUND Currently, radiation therapy treatment planning system intends biological optimization that relies heavily upon plan metrics from tumor control probability (TCP) and normal tissue complication probability (NTCP) modeling. Implementation and expansion of TCP and NTCP models with alternative data is an important step towards reliable radiobiological treatment planning. In this retrospective single institution study, the treatment charts of 139 lung cancer patients treated with chemo-radiotherapy were reviewed and correlated dosimetric predictors with the incidence of esophagitis and established NTCP model of esophagitis grade 1 and 2 for lung cancer patients. METHODS Esophagus is an organ at risk (OAR) in lung cancer radiotherapy (RT). Esophagitis is a common toxicity induced by RT. In this study, dose volume parameters Vx (Vx: percentage esophageal volume receiving ≥ x Gy) and mean esophagus dose (MED) as quantitative dose-volume metrics, the esophagitis grade 1 and 2 as endpoints, were reviewed and derived from the treatment planning system and the electronic medical record system. Statistical analysis of binary logistic regression and probit were performed to have correlated the probability of grade 1 and 2 esophagitis to MED and Vx. IBM SPSS software version 24 at 5% significant level (α = 0.05) was used in the statistical analysis. RESULTS The probabilities of incidence of grade 1 and 2 esophagitis proportionally increased with increasing the values of Vx and MED. V20, V30, V40, V50 and MED are statistically significant good dosimetric predictors of esophagitis grade 1. 50% incidence probability (TD50) of MED for grade 1 and 2 esophagitis were determined. Lyman Kutcher Burman model parameters, such as, n, m and TD50, were fitted and compared with other published findings. Furthermore, the sigmoid shaped dose responding curve between probability of esophagitis grade 1 and MED were generated respecting to races, gender, age and smoking status. CONCLUSIONS V20, V30, V40 and V50 were added onto Quantitative Analysis of Normal Tissue Effects in the clinic, or QUANTEC group's dose constrains of V35, V50, V70 and MED. Our findings may be useful as both validation of 3-Dimensional planning era models and also additional clinical guidelines in treatment planning and plan evaluation using radiobiology optimization.

Abstract
PURPOSE To explore the feasibility and safety of simultaneous integrated boost technology (SIB) with elective nodal irradiation (ENI) to the cervical and upper mediastinal lymph node (LN) regions in upper thoracic esophageal squamous cell carcinoma (ESCC). MATERIAL AND METHODS Patients with pathologically proven unresectable upper thoracic ESCC were assigned 50.4 Gy/28 fractions (F) to the clinical target volume (encompassing the ENI area of cervical and upper mediastinal LN regions) and a boost of 63 Gy/28 F to the gross tumor volume. Chemotherapy consisted of courses of concurrent cisplatin (20 mg/m2) and docetaxel (20 mg/m2) weekly for 6 weeks. The primary endpoint was toxicity. RESULTS Between Jan 2017 and Dec 2019, 28 patients were included. The median follow-up time for all patients was 24.6 months (range 1.9-53.5). Radiation-related acute toxicity included esophagitis, pneumonia and radiodermatitis, all of which were well managed and reversed. Late morbidity included esophageal ulcer, stenosis, fistula and pulmonary fibrosis. Grade III esophageal stenosis and fistula was seen in 11% (3/28) and 14% (4/28) patients, respectively. The cumulative incidence rate of late esophageal toxicity was 7.7%, 19.2% and 24.6% at 6, 12 and 18 months, respectively. There was significant difference of the occurrence of severe late esophageal toxicity among the different volume levels of the esophagus, and cervical and upper mediastinal LNs which received ≥ 63 Gy stratified by the tertiles (p = 0.014). CONCLUSIONS Despite the acceptably tolerated acute toxicity of SIB in concurrent CRT with ENI to the cervical and upper mediastinal LN regions for upper thoracic ESCC, the incidence of severe late esophageal toxicity was relatively high. Cautions are provided against easy clinical application of SIB (50.4 Gy/28F to the CTV, 63 Gy/28F to the GTV) in upper thoracic ESCC. Further exploration on dose optimization is warranted.

Abstract
BACKGROUND In patients with nasopharyngeal cancer (NPC), radiation-induced temporal lobe injury (TLI) is the most dreaded late-stage complication following radiation therapy (RT). We currently lack a definitive algorithmic administration for this entity. In the meantime, the pathogenesis of TLI and the mechanism-based interventions to prevent or treat this adverse effect remain unknown. To better answer the aforementioned questions, it is necessary to comprehend the intellectual foundations and prospective trends of this field through bibliometric analysis. METHODS Articles were gathered from the Web of Science Core Collection (WoSCC) database between 2000 and 2022. CiteSpace was utilized to create a country/institutional co-authorship network, perform dual-map analysis, and find keywords with citation bursts. VOSviewer was used to build networks based on author co-authorship, journal citation, co-citation analysis of authors, references, and journals, and keyword co-occurrence. RESULTS A total of 140 articles and reviews were included in the final analysis. The number of publications has steadily increased with some fluctuations over the years. The country and institution contributing most to this field are the China and Sun Yat-Sen University. Han Fei was the most prolific author, while Lee Awm was the most frequently cited. The analysis of co-occurrence revealed three clusters, including: "radiation-induced injury or necrosis in NPC," "clinical studies on chemotherapy/radiotherapy complications and survival in recurrent NPC," and "IMRT/chemotherapy outcomes and toxicities in head and neck cancer"). Most recent keyword bursts were "volume," "temporal lobe injury," "toxicities," "model," "survival," "intensity modulated radiotherapy," "induced brain injury," "head and neck cancer," and "temporal lobe." CONCLUSION This study provides some insights of the major areas of interest in the field of radiation-induced TLI in patients with NPC by bibliometric analyses. This study assists scholars in locating collaborators and significant literature in this field, provides guidance for publishing journals, and identifies research hotspots. This analysis acknowledges significant contributions to the discipline and encourages the scientific community to conduct additional research.

Abstract
Since the nuclear bomb attack against Hiroshima and Nagasaki in 1945, the world has advanced in nuclear technology. Today, a nuclear bomb could target a large-scale attack, at a longer range, and with much greater destructive force. People are increasingly concerned about the potential destructive humanitarian outcomes. We discuss actual conditions detonation of an atomic bomb would create, radiation injuries, and diseases. We also address concerns about functionality of medical care systems and other systems that support medical systems (i.e., transport, energy, supply chain, etc. systems) following a massive nuclear attack and whether citizens able to survive this.

Abstract
OBJECTIVE To evaluate the healthcare resource impact of radiation injury following prostate cancer treatment. METHODS Using IBM MarketScan, we performed a retrospective study of men with prostate cancer who were treated with radiotherapy and subsequently developed low-grade (LGRI) and high-grade radiation injury (HGRI). Radiation injury diagnoses included bladder neck stenosis, hematuria/cystitis, fistula, ureteral stricture, and incontinence. LGRI and HGRI included injury diagnosis without intervention and with intervention, respectively. Health care visits and costs were measured over 5 time periods including 2 years before radiation, 1 year before radiation, radiation to injury diagnosis, injury diagnosis to first intervention (LGRI), and following first intervention (HGRI). Negative binomial regression modeling was used to assess the effect of radiation injury on average cost adjusting for demographics and comorbidities. RESULTS Between 2008 and 2017, we identified 121,027 men who received radiotherapy following prostate cancer diagnosis of which 10,057 (8.3%) experienced a HGRI. The frequency of urologic visits and average costs were similar in those without injury and LGRI. However, men with HGRI experienced higher visit frequency and monthly costs. Amongst high-grade injuries, urinary fistula had the highest frequency of visit utilization at 378 visits before first intervention and 245 visits after first intervention. Following radiation injury diagnosis, the average monthly cost was twice as high in those with HGRI ($85.78) compared to LGRI ($38.66). CONCLUSIONS HGRI was associated with increased urologic health care use and average monthly cost when compared to those who experienced LGRI or no injury. Urinary fistula was associated with the largest resource burden.

Abstract
PURPOSE We aimed to assess the outcomes and patterns of toxicity in patients with melanoma brain metastases (MBM) treated with stereotactic radiosurgery (SRS) with or without immunotherapy (IO). METHODS From a prospective registry, we reviewed MBM patients treated with single fraction Gamma Knife SRS between 2008 and 2021 at our center. We recorded all systemic therapies (chemotherapy, targeted therapy, or immunotherapy) administered before, during, or after SRS. Patients with prior brain surgery were excluded. We captured adverse events following SRS, including intralesional hemorrhage (IH), radiation necrosis (RN) and local failure (LF), as well as extracranial disease status. Distant brain failure (DBF), extracranial progression-free survival (PFS) and overall survival (OS) were determined using a cumulative Incidence function and the Kaplan-Meier method. RESULTS Our analysis included 165 patients with 570 SRS-treated MBM. Median OS for patients who received IO was 1.41 years versus 0.79 years in patients who did not (p = 0.04). Ipilimumab monotherapy was the most frequent IO regimen (30%). In the absence of IO, the cumulative incidence of symptomatic (grade 2 +) RN was 3% at 24 months and remained unchanged with respect to the type or timing of IO. The incidence of post-SRS g2 + IH in patients who did not receive systemic therapy was 19% at 1- and 2 years compared to 7% at 1- and 2 years among patients who did (HR: 0.33, 95% CI 0.11-0.98; p = 0.046). Overall, neither timing nor type of IO correlated to rates of DBF, OS, or LF. Among patients treated with IO, the median time to extracranial PFS was 5.4 months (95% IC 3.2 - 9.1). CONCLUSION The risk of g2 + IH exceeds that of g2 + RN in MBM patients undergoing SRS, with or without IO. IH should be considered a critical adverse event following MBM treatments.

Abstract
PURPOSE Radiation-associated cardiac disease is a major cause of morbidity/mortality among childhood cancer survivors. Radiation dose-response relationships for cardiac substructures and cardiac diseases remain unestablished. METHODS Using the 25,481 5-year survivors of childhood cancer treated from 1970 to 1999 in the Childhood Cancer Survivor Study, we evaluated coronary artery disease (CAD), heart failure (HF), valvular disease (VD), and arrhythmia. We reconstructed radiation doses for each survivor to the coronary arteries, chambers, valves, and whole heart. Excess relative rate (ERR) models and piecewise exponential models evaluated dose-response relationships. RESULTS The cumulative incidence 35 years from diagnosis was 3.9% (95% CI, 3.4 to 4.3) for CAD, 3.8% (95% CI, 3.4 to 4.2) for HF, 1.2% (95% CI, 1.0 to 1.5) for VD, and 1.4% (95% CI, 1.1 to 1.6) for arrhythmia. A total of 12,288 survivors (48.2%) were exposed to radiotherapy. Quadratic ERR models improved fit compared with linear ERR models for the dose-response relationship between mean whole heart and CAD, HF, and arrhythmia, suggesting a potential threshold dose; however, such departure from linearity was not observed for most cardiac substructure end point dose-response relationships. Mean doses of 5-9.9 Gy to the whole heart did not increase the risk of any cardiac diseases. Mean doses of 5-9.9 Gy to the right coronary artery (rate ratio [RR], 2.6 [95% CI, 1.6 to 4.1]) and left ventricle (RR, 2.2 [95% CI, 1.3 to 3.7]) increased risk of CAD, and to the tricuspid valve (RR, 5.5 [95% CI, 2.0 to 15.1]) and right ventricle (RR, 8.4 [95% CI, 3.7 to 19.0]) increased risk of VD. CONCLUSION Among children with cancer, there may be no threshold dose below which radiation to the cardiac substructures does not increase the risk of cardiac diseases. This emphasizes their importance in modern treatment planning.

Abstract
Objective: To compare the incidence of radiation-related toxicities between conventional and hypofractionated intensity-modulated radiation therapy (IMRT) for limited-stage small cell lung cancer (SCLC), and to explore the risk factors of hypofractionated radiotherapy-induced toxicities. Methods: Data were retrospectively collected from consecutive limited-stage SCLC patients treated with definitive concurrent chemoradiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from March 2016 to April 2022. The enrolled patients were divided into two groups according to radiation fractionated regimens. Common Terminology Criteria for Adverse Events (CTCAE, version 5.0) was used to evaluate the grade of radiation esophagus injuries and lung injuries. Logistic regression analyses were used to identify factors associated with radiation-related toxicities in the hypofractionated radiotherapy group. Results: Among 211 enrolled patients, 108 cases underwent conventional IMRT and 103 patients received hypofractionated IMRT. The cumulative incidences of acute esophagitis grade ≥2 [38.9% (42/108) vs 35.0% (36/103), P=0.895] and grade ≥ 3 [1.9% (2/108) vs 5.8% (6/103), P=0.132] were similar between conventional and hypofractionated IMRT group. Late esophagus injuries grade ≥2 occurred in one patient in either group. No differences in the cumulative incidence of acute pneumonitis grade ≥2[12.0% (13/108) vs 5.8% (6/103), P=0.172] and late lung injuries grade ≥2[5.6% (6/108) vs 10.7% (11/103), P=0.277] were observed. There was no grade ≥3 lung injuries occurred in either group. Using multiple regression analysis, mean esophageal dose ≥13 Gy (OR=3.33, 95% CI: 1.23-9.01, P=0.018) and the overlapping volume between planning target volume (PTV) and esophageal ≥8 cm(3)(OR=3.99, 95% CI: 1.24-12.79, P=0.020) were identified as the independent risk factors associated with acute esophagitis grade ≥2 in the hypofractionated radiotherapy group. Acute pneumonitis grade ≥2 was correlated with presence of chronic obstructive pulmonary disease (COPD, P=0.025). Late lung injuries grade ≥2 was correlated with tumor location(P=0.036). Conclusions: Hypofractionated IMRT are tolerated with manageable toxicities for limited-stage SCLC patients treated with IMRT. Mean esophageal dose and the overlapping volume between PTV and esophageal are independently predictive factors of acute esophagitis grade ≥2, and COPD and tumor location are valuable factors of lung injuries for limited-stage SCLC patients receiving hyofractionated radiotherapy. Prospective studies are needed to confirm these results.

Radiation-induced oral mucositis (RIOM) is one of the common toxic reactions from ionizing radiation and normal tissue injuries as a complication of radiation therapy and chemotherapy. Radiation therapy is an option for the treatment of head and neck cancer (HNC). The use of natural products is an alternative therapy for RIOM. This review aimed to describe the effectiveness of natural-based products (NBPs) in reducing the severity, pain score, incidence, oral lesion size, and other symptoms such as dysphagia, dysarthria, and odynophagia. This systematic review follows the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Pubmed, ScienceDirect, and Ebscohost-CINAHL Plus databases were used for article searches. The inclusion criteria were studies published from 2012 to 2022 with full text available, in English, a study in humans, and a Randomized Clinical Trial (RCT) that evaluate the effect of NBPs therapy in RIOM patients diagnosed with HNC. This study's population was HNC patients who had oral mucositis after receiving radiation or chemical therapy. The NBPs were manuka honey, thyme honey, aloe vera, calendula, zataria multiflora, Plantago major L., and turmeric. Eight of the twelve included articles showed significant effectiveness against RIOM in various parameters, such as a decrease in severity, incidence rate, pain score, oral lesion size, and the other symptoms of oral mucositis such as dysphagia and burning mouth syndrome. This review concludes that NBPs therapy is effective for RIOM in HNC patients.

Abstract
BACKGROUND Cervical cancer is one of the most common gynecological malignant tumors. Radiation enteritis (RE) leads to radiotherapy intolerance or termination of radiotherapy, which negatively impacts the therapeutic effect and seriously affects the quality of life of patients. If the incidence of RE in patients can be predicted in advance, and targeted clinical preventive treatment can be carried out, the side effects of radiotherapy in cervical cancer patients can be significantly reduced. Furthermore, accurate prediction of RE is essential for the selection of individualized radiation dose and the optimization of the radiotherapy plan.
AIM To analyze the relationships between severe acute RE (SARE) of cervical cancer radiotherapy and clinical factors and dose-volume parameters retrospectively.
METHODS We included 50 cervical cancer patients who received volumetric modulated arc therapy (VMAT) from September 2017 to June 2018 in the Department of Radiotherapy at The First Affiliated Hospital Soochow University. Clinical and dose-volume histogram factors of patients were collected. Logistic regression analysis was used to evaluate the predictive value of each factor for SARE. A nomogram to predict SARE was developed (SARE scoring system ≥ 3 points) based on the multiple regression coefficients; validity was verified by an internal verification method.
RESULTS Gastrointestinal and hematological toxicity of cervical cancer VMAT gradually increased with radiotherapy and reached the peak at the end of radiotherapy. The main adverse reactions were diarrhea, abdominal pain, colitis, anal swelling, and blood in the stool. There was no significant difference in the incidence of gastrointestinal toxicity between the radical and postoperative adjuvant radiotherapy groups (P > 0.05). There were significant differences in the small intestine V20, V30, V40, and rectal V40 between adjuvant radiotherapy and radical radiotherapy after surgery (P < 0.05). Univariate and multivariate analyses revealed anal bulge rating (OR: 14.779, 95%CI: 1.281-170.547, P = 0.031) and disease activity index (DAI) score (OR: 53.928, 95%CI: 3.822-760.948, P = 0.003) as independent predictors of SARE.
CONCLUSION Anal bulge rating (> 0.500 grade) and DAI score (> 2.165 points) can predict SARE. The nomogram shows potential value in clinical practice.

Abstract
INTRODUCTION Smoking during breast radiotherapy (RT) may be associated with radiation-induced skin injury (RISI). We aimed to determine if a urinary biomarker of tobacco smoke exposure is associated with increased rates of RISI during and after breast RT. PATIENTS AND METHODS Women with Stage 0-IIIA breast cancer treated with breast-conserving surgery or mastectomy followed by RT to the breast or chest wall with or without regional nodal irradiation were prospectively enrolled on a multicenter study assessing acute/late RISI. 980 patients with urinary cotinine (UCot) measurements (baseline and end-RT) were categorized into three groups. Acute and late RISI was assessed using the ONS Acute Skin Reaction scale and the LENT-SOMA Criteria. RESULTS Late Grade 2+ and Grade 3+ RISI occurred in 18.2% and 1.9% of patients, respectively-primarily fibrosis, pain, edema, and hyperpigmentation. Grade 2+ late RISI was associated with UCot group (P= 006). Multivariable analysis identified UCot-based light smoker/secondhand smoke exposure (HR 1.79, P= .10) and smoking (HR 1.60, p = .06) as non-significantly associated with an increased risk of late RISI. Hypofractionated breast RT was associated with decreased risk of late RISI (HR 0.51, P=.03). UCot was not associated with acute RISI, multivariable analysis identified race, obesity, RT site/fractionation, and bra size to be associated with acute RISI. CONCLUSIONS Tobacco exposure during breast RT may be associated with an increased risk of late RISI without an effect on acute toxicity. Smoking cessation should be encouraged prior to radiotherapy to minimize these and other ill effects of smoking.

Abstract
BACKGROUND AND PURPOSE To investigate the association between clinician-scored toxicities and patient-reported health-related quality of life (HRQoL), in early-stage (ES-) and locally-advanced (LA-) non-small cell lung cancer (NSCLC) patients receiving loco-regional radiotherapy, included in the international real-world REQUITE study. MATERIALS AND METHODS Clinicians scored eleven radiotherapy-related toxicities (and baseline symptoms) with the Common Terminology Criteria for Adverse Events version 4. HRQoL was assessed with the European Organization for Research and Treatment of Cancer core HRQoL questionnaire (EORTC-QLQ-C30). Statistical analyses used the mixed-model method; statistical significance was set at p = 0.01. Analyses were performed for baseline and subsequent time points up to 2 years after radiotherapy and per treatment modality, radiotherapy technique and disease stage. RESULTS Data of 435 patients were analysed. Pre-treatment, overall symptoms, dyspnea, chest wall pain, dysphagia and cough impacted overall HRQoL and specific domains. At subsequent time points, cough and dysphagia were overtaken by pericarditis in affecting HRQoL. Toxicities during concurrent chemo-radiotherapy and 3-dimensional radiotherapy had the most impact on HRQoL. Conversely, toxicities in sequential chemo-radiotherapy and SBRT had limited impact on patients' HRQoL. Stage impacts the correlations: LA-NSCLC patients are more adversely affected by toxicity than ES-NSCLC patients, mimicking the results of radiotherapy technique and treatment modality. CONCLUSION Pre-treatment symptoms and acute/late toxicities variously impact HRQoL of ES- and LA-NSCLC patients undergoing different treatment approaches and radiotherapy techniques. Throughout the disease, dyspnea seems crucial in this association, highlighting the additional effect of co-existing comorbidities. Our data call for optimized radiotherapy limiting toxicities that may affect patients' HRQoL.

Abstract
Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned coprimary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The purpose of this update was to determine differences in patient-reported chronic toxicity and disease outcomes with intensity-modulated radiation therapy (IMRT) compared with conventional pelvic radiation. Patients with cervical and endometrial cancers who received postoperative pelvic radiation were randomly assigned to conventional radiation therapy (CRT) or IMRT. Toxicity and quality of life were assessed using Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events, Expanded Prostate Cancer Index Composite (EPIC) bowel and urinary domains, and Functional Assessment of Cancer Therapy-General. Between 2012 and 2015, 279 eligible patients were enrolled to the study with a median follow-up of 37.8 months. There were no differences in overall survival (P = .53), disease-free survival (P = .21), or locoregional failure (P = .81). One year after RT, patients in the CRT arm experienced more high-level diarrhea frequency (5.8% IMRT v 15.1% CRT, P = .042) and a greater number had to take antidiarrheal medication two or more times a day (1.2% IMRT v 8.6% CRT, P = .036). At 3 years, women in the CRT arm reported a decline in urinary function, whereas the IMRT arm continued to improve (mean change in EPIC urinary score = 0.5, standard deviation = 13.0, IMRT v -6.0, standard deviation = 14.3, CRT, P = .005). In conclusion, IMRT reduces patient-reported chronic GI and urinary toxicity with no difference in treatment efficacy at 3 years.

Abstract
OBJECTIVES To evaluate the risk of developing eye lens opacities and cataracts among physicians and healthcare workers occupationally exposed to radiation. METHODS Our literature search captured articles published in Embase, Web of Science, PubMed, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and Google Scholar databases until September 2021. Then, we retrieved articles reporting cataracts and eye lens opacities induced by radiation exposure among healthcare professionals. The outcomes of interest were cataracts, nuclear opacity, cortical opacity, posterior subcapsular opacity, and any lens opacity. RESULTS Of the 4123 articles identified, 15 studies met the inclusion criteria. Healthcare workers exposed to radiation had a significantly greater risk of posterior subcapsular cataracts (PSCs), cataracts, and any lens opacities than those of the non-exposed participants (p<0.05). The cortical opacity was not significantly different between the exposed and non-exposed participants (p>0.05). Radiation was not determined to be a risk factor for nuclear opacity as it was significantly greater in the control group than the exposed participants. Subgroup analysis revealed that nurses had the highest risk for PSCs (risk ratio = 4.00), followed by interventional cardiologists (risk ratio = 3.85). CONCLUSION The risk of posterior subcapsular opacities and cataracts is significantly higher in healthcare workers with occupational radiation exposure than in non-exposed workers, highlighting the necessity to enhance and promote the wearing of protective measures with high safety levels.

Abstract
INTRODUCTION In this study, we investigate factors associated with radionecrosis (RN) in HER2 + (human epidermal growth factor receptor 2) patients with brain metastases (BrM) treated with stereotactic radiosurgery (SRS). METHODS Patients with HER2 + breast cancer BrM treated with SRS (2010-2020) were identified from an institutional database. The incidence of RN was determined per treated BrM according to serial imaging and/or histology. Factors associated with RN such as age, RT dose, BrM volume, and initiation of Trastuzumab Emtansine (T-DM1) were investigated with univariate and multivariable analyses (MVA). RESULTS 67 HER2 + patients with 223 BrM were identified. 21 patients (31.3%) were treated with T-DM1 post-SRS, including 14 patients (20.9%) who received T-DM1 within 12 months of SRS. The median follow-up was 15.6 (interquartile range (IQR) 5.4-35.3) months. The overall probability of RN post-SRS was 21.6% (95% confidence interval (CI) 2.7-10.7), and the 1 and 2 year risk was 6.7% (95% CI 2.7-10.7) and 15.2% (95% CI 9.2-21.3). MVA identified T-DM1 treatment post-SRS (hazard ratio (HR) 2.5, 95% CI 1.2-5.3, p = 0.02) and equivalent dose in 2 Gy fractions (EQD2) > 90 Gy2 (HR 2.4, 95% CI 1.1-5.1, p = 0.02) as predictors of RN. Patients treated with T-DM1 and SRS had a 29.9% (95% CI 15.3-44.6%) probability of RN, with a 25.2% (95% CI 12.8-37.6%) risk at 1- and 2 years post-T-DM1. The majority of RN were symptomatic (71%), with a median time to RN of 4.8 months. CONCLUSION T-DM1 exposure post-SRS was associated with a higher risk of RN among patients with HER2 + BrM.

Abstract
PURPOSE To explore the potential protective effect of Kanglaite injection against radiotherapy-induced mucositis in patients with head and neck cancer. PATIENTS AND METHODS This was an open-label, single-arm, and phase II trial. The primary endpoint was the incidence of grade 3-4 radiation-induced mucositis. The secondary endpoints were hematological toxicity, non-hematological toxicity, nutritional status, and quality of life. All patients received 20g Kanglaite daily concurrently with radiotherapy. RESULTS The data of 46 patients were available for analysis. The incidence rates of grade 3 mucositis, pain, dysphagia, and neutropenia were 10.9%, 2.2%, 10.9%, and 6.5%, respectively, while the incidence of grade 4 acute toxicities was zero. The rate of opioid use was 2.2%. Radiotherapy dose reduction was 2.2% and no irradiation field was modified. The nutritional supports were oro-enteral nutritional supplements (13.0%), TPN (10.9%), and feeding tubes (0%) during radiotherapy. After radiotherapy, 52.2% of patients lost weight, and the weight loss was <10%. The mean pain score in the QLQ-H&N35 and QLQ-C30 was <50. Patients had nearly normal physical, emotional, and cognitive functions. CONCLUSIONS A low incidence of grade 3-4 radiation-induced mucositis and no severe acute toxic events, with favorable nutritional status and quality of life, were observed in cancer patients after Kanglaite injection. Our findings highlight the need for a prospective, multicenter, and randomized study to investigate the effect of Kanglaite injection on the reduction of radiation-induced mucositis in patients with head and neck cancer.

Abstract
Oral mucositis (OM) is a common, highly symptomatic complication of cancer therapy that affects patients' function, quality of life, and ability to tolerate treatment. In certain patients with cancer, OM is associated with increased mortality. Research on the management of OM is ongoing. Oral mucosal toxicities are also reported in targeted and immune checkpoint inhibitor therapies. The objective of this article is to present current knowledge about the epidemiology, pathogenesis, assessment, risk prediction, and current and developing intervention strategies for OM and other ulcerative mucosal toxicities caused by both conventional and evolving forms of cancer therapy.

Abstract
High-dose radiation exposures of humans occur every year around the world, and may lead to harmful tissue reactions. This review aims to look at the available information sources that can help answering the question of how often these events occur yearly on a global scale. In the absence of comprehensive databases of global occurrence, publications on radiation accidents in all uses of radiation and on rates of high-dose events in different medical uses of radiation have been reviewed. Most high-dose radiation exposures seem to occur in the medical uses of radiation, reflecting the high number of medical exposures performed. In therapeutic medical uses, radiation doses are purposely often given at levels known to cause deterministic effects, and there is a very narrow range in which the medical practitioner can operate without causing severe unacceptable outcomes. In interventional medical uses, there are scenarios in which the radiation dose given to a patient may reach or exceed a threshold for skin effects, where this radiation dose may be unavoidable, considering all benefits and risks as well as benefits and risks of any alternative procedures. Regardless of if the delivered dose is unintended, unnecessary or unavoidable, there are estimates published of the rates of high-dose events and of radiation-induced tissue injuries occurring in medical uses. If this information is extrapolated to a global scenario, noting the inherent limitations in doing so, it does not seem unreasonable to expect that the global number of radiation-induced injuries every year may be in the order of hundreds, likely mainly arising from medical uses of radiation, and in particular from interventional fluoroscopy procedures and external beam radiotherapy procedures. These procedures are so frequently employed throughout the world that even a very small rate of radiation-induced injuries becomes a substantial number when scaled up to a global level.

Abstract
OBJECTIVE to investigate the clinical, hormonal-metabolic and structural features of parathyroid injuries in sur-vivors exposed to ionizing radiation after the Chornobyl NPP accident in adulthood and childhood, both with theirconnections to other non-cancerous endocrine disorders, and to establish the respective interhormonal and dys-metabolic relationships. MATERIALS AND METHODS Clinical effects of ionizing radiation on the endocrine system in persons affected by theChornobyl NPP accident (n = 224) and their descendants (n = 146), compared with the general population sample(n = 70) were the study object. All patients underwent the ultrasound thyroid and parathyroid examination. Thegenerally recognized clinical, anthropometric (body weight, height, thigh volume, body mass index), instrumental(ultrasound examination of thyroid and parathyroid glands), laboratory (biochemical, hormonal), and statisticalmethods were applied. Parametric and nonparametric statistical methods were used in data processing. The value ofp < 0.05 was considered a statistically significant. RESULTS No significant difference was found in the incidence of carbohydrate metabolic disorders in the ChornobylNPP (ChNPP) accident consequences clean-up workers (ACCUW), evacuees from the NPP 30-km exclusion zone, res-idents of radiologically contaminated areas and in the control group in whom the parathyroid hyperplasia wasdetected. There was a significant increase in the incidence of arterial hypertension among ACCUW who had parathy-roid hyperplasia (76.9%) vs. the control group (51.2%). In cases of parathyoid hyperplasia the vitamin D levels weresignificantly lower than without it. Vitamin D insufficiency/deficiency was found in 94% of the surveyed subjects.The average level of parathyroid hormone in blood serum was significantly higher in the ACCUW of «iodine» period withdiagnosed parathyroid hyperplasia than in the control group: (57.2 ± 2.87) pg / ml against (32.74 ± 3.58) pg / ml,p < 0.05. Results of multivariative analysis indicated a strong association of vitamin 25(OH)D insufficiency/defi-ciency with development of thyroid disease, carbohydrate metabolic disorders, cardiovascular disease, osteo-penia/osteoporosis. parathyroid ultrasound scan was at that an effective diagnostic method for primary screeningfor parathyroid hyperplasia and regular monitoring of the treatment efficiency. When examining children bornto parents irradiated after the ChNPPA the parathyroid hyperplasia (58%) and low serum content of vitamin D(11.6 ± 3.5) nmol / l were most often found in children living on radiologically contaminated territories (RCT).A strong correlation was established between the HOMA insulin resistance index and serum content of vitamin D(r = 0.65), parathyroid hormone (r = 0.60), and free thyroxine (r = 0.68) in the group of children born to parents irra-diated after the ChNPPA, having got chronic autoimmune thyroiditis, which indicated a relationship between thy-roid function, impaired carbohydrate and fat metabolism and the state of parathyroids. CONCLUSIONS No difference in the incidence of carbohydrate metabolic disorders was found in the ChNPP ACCUW,evacuees from the 30-km exclusion zone, and residents of radiologically contaminated territories in whom parathy-roid hyperplasia was detected vs. the control group. Patients with parathyroid hyperplasia were found to be defi-cient in vitamin D in 94% of cases, and level of latter was significantly lower than under the normal parathyroid size.There was a significant increase in the incidence of diagnosed arterial hypertension among ACCUW who had parathy-roid hyperplasia vs. the control group: (76.9 ± 3.5)% vs. (51.2 ± 3.7)%. According to multivariate analysis a strongassociation between the vitamin 25(OH)D insufficiency/deficiency and development of thyroid disease, carbohydratemetabolic disorders, cardiovascular disease, and osteopenia/osteoporosis was established. The average level of pa-rathyroid hormone in the blood serum of the ChNPP ACCUW of the «iodine» period with diagnosed parathyroid hyper-plasia was significantly higher (57.2 ± 2.87) pg / ml against (32.74 ± 3.58) pg / ml; p <0,05) in the control group.

Abstract
OBJECTIVE to explore proliferative potential of peripheral blood lymphocytes of Chornobyl clean-up workers and persons with malignant neoplasms of the oral cavity, oropharynx and laryngopharynx by level of expression of cyclin D1 and quantitative parameters of cell cycle. MATERIALS AND METHODS A total of 294 men aged (58.47 ± 7.32) were surveyed, 215 of them were Chornobyl clean"up workers (1986-1987), exposed at the dose range 10.43-3623.31 mSv; 49 persons of the control group and 30persons with malignant neoplasms of the oral cavity, oropharynx and laryngopharynx at III, IVА and IVВ stages ofthe disease. The analysis of parameters of cell cycle and proliferative activity of peripheral blood (PB) lymphocyteswas performed using the flow cytometry. The evaluation of distribution of cells by G0/G1, S, G2/M cell cycle phaseswas done in vivo and in in vitro. Proliferative potential was analyzed by level of expression of cytoplasmic protein ofcyclin D1. RESULTS Proliferative potential of PB lymphocytes of Chornobyl clean"up workers and persons with malignant neo"plasms of the oral cavity, oropharynx and laryngopharynx was assessed. An increase in the level of spontaneousсyclin D1 expression and disturbance of сyclin D1-dependent regulation of cell cycle of PB lymphocytes after mito"gen activation were determined in the Chornobyl clean-up workers. An increase in pool of cells in the S" and G2/M"phases of cell cycle was detected, which characterizes high proliferative potential of PB lymphocytes. These changesare most pronounced in the subgroup of persons with a radiation dose of D > 500 mSv, and in persons with oncolo"gical pathology. CONCLUSIONS A positive linear dependence has been established between the radiation dose and the number of cellsin the S"phase of cell cycle in the subgroup of Chornobyl clean"up workers with a radiation dose of D > 500 mSv. The detected changes of cyclin D1-dependent regulation of cell cycle and proliferative status of lymphocytes depend on the radiation dose, can be a manifestation of genome instability and be a cause for risks of oncogenesis, in a remote period after radiation exposure.

Abstract
OBJECTIVE to analyze comorbid pathology by methods of its quantitative assessment in servicemen exposed toextreme factors of military service (a set of factors of radiation accidents, the influence of modern armed conflictsand modern combat trauma without blood loss). MATERIALS AND METHODS Studies of comorbid pathology were performed in 613 servicemen who were treated at theclinical base of the Ukrainian Military Medical Academy (UMMA) in National Military Medical Clinical Center «MainMilitary Clinical Hospital» NMMCC «MMCH» during 1989-2018 years. Soldiers who suffered from acute radiation sick-ness (ARS) in 1961 (n = 34), participants in the liquidation of the consequences of the Chornobyl catastrophe(PLCChC) 15 years after participating in the elimination of its consequences and in a later period (respectivelyPLCChC 1st group (n = 59) and the 2nd group (n = 337)). Soldiers are participants in the anti-terrorist operation(ATO)/Combined Forces (CFO) operation who did not receive modern combat injuries with blood loss (participants inthe ATO/CFO, n = 183). All servicemen did not have any diseases limiting their fitness capabilities for military serv-ice before being exposed to extreme factors of military service. A cumulative CIRS scale was used to comprehensive-ly assess comorbidity. RESULTS With increasing time after participation in the elimination of the consequences of radiation accidents, thecourse of arterial hypertension (AH) is aggravated, but the dose-dependence of the severity of AH on the receivedradiation dose has not been established. The easier course of hypertension in ATO/CFO servicemen compared to ARSremote servicemen and group 2 PLCChC servicemen can be explained by their younger age at the time of the surveyand less time after exposure to extreme military service factors. In the military in the remote period after exposureto a complex of factors of radiation accidents, the frequency of diagnosing diseases by individual organs and bodysystem increases comparing to non-irradiated servicemen. The total number of disease severity scores on the cumu-lative scale of CIRS diseases is also higher. However, a dose-dependent effect of the severity of comorbid patholo-gy was also not found. These data indicate a higher prevalence of comorbid pathology in servicemen affected by acomplex of factors of radiation accf5idents, compared with participants in the anti-terrorist operation / environ-mental protection. However, the lower severity of comorbid pathology in ATO/CFO participants can also be explainedby their younger age at the time of the survey and less time after exposure to extreme factors of military service. CONCLUSIONS For servicemen, with increasing time after participation in the elimination of the consequences ofradiation accidents, the course of hypertension without its dose dependence becomes more difficult. The total num-ber of disease severity scores on the cumulative scale of CIRS diseases in servicemen in the remote period after participation in the elimination of the consequences of radiation accidents is higher than in non-irradiated service-men. However, a dose-dependent effect of the severity of comorbid pathology was also not found.

Abstract
OBJECTIVE to evaluate the parameters of inflammatory reaction and oxidative stress in patients with non-alcoholicfatty liver disease (NAFLD) in the remote period after the influence of the Chornobyl accident factors. MATERIALS AND METHODS Eighty two patients with NAFLD who had been exposed to ionizing radiation as a result ofthe Chornobyl accident and have concomitant cardiovascular pathology were examined. Hematological parametersand the level of highly sensitive C-reactive protein (hsCRP) were determined, and the content of products of oxida-tive modification of lipids and proteins was evaluated. RESULTS Activation of the processes of oxidative modification of lipids and proteins was observed in most patientswith NAFLD. According to the level of hsCRP, the presence of subclinical inflammation and the risk of developingcomplicated cardiovascular pathology was found in 58 % of patients with NAFLD. The neutrophil / lymphocyte ratiocorrelates positively with hsCRP and can be used as an available routine clinical marker for selection among patientswith NAFLD persons with increased risk of cardiovascular complications. CONCLUSIONS HsCRP, oxidative modification products of lipids and proteins, ESR, and leukograms should be used toassess the degree of systemic inflammation in people affected by the Chornobyl accident, suffering NAFLD with con-comitant cardiovascular disease.

Abstract
UNLABELLED The objective was to analyze the relative telomere length (RTL) of peripheral blood lymphocytes depending onmyocardium structural and functional state in emergency workers (EW) of the Chornobyl accident who suffered fromcoronary arteries stenotic atherosclerosis. MATERIALS AND METHODS There were examined 60 male EW who operated at the Chornobyl nuclear power plant at1986 and 25 male non-irradiated persons (control group - CG) with coronary heart disease (CHD). Everyone EW andCG patients were almost healthy before the accident. During the period 2016-2021, they underwent a comprehen-sive clinical and laboratory examination, echodopplercardiographic examination and determination of RTL by fluo-rescent hybridization in situ using laser flow cytometry. RESULTS EW almost did not differ from CG according to its clinical characteristics, the presence of risk factors,indices of systolic and diastolic heart functions, as well as RTL. The analysis of variance showed that RTL was influ-enced by the fact of irradiation in combination with obesity (p = 0.020). At normal body weight, RTL average valuein CG was significantly higher than in EW (p = 0.023). According to the results of hierarchical cluster analysis of twovariables as RTL and end-diastolic volume normalized by body surface area (EDV/BSA), EW and CG patients togeth-er were divided into two subgroups. The first subgroup (1st cluster) differed from the second (2nd cluster) by signi-ficantly larger average values of left ventricle (LV) EDV and end-systolic volume (ESV) as well as EDV/BSA andESV/BSA, LV myocardial mass (MM) and MM/BSA, reduced ejection fraction (EF). In patients of the 1st cluster telom-eres were significantly shorter than in the 2nd one (10,3 ± 1.7 vs. 14.3 ± 2.0 at p = 0.000). The increase of myocar-dial mass and LV wall thickness caused the development of its hypertrophy. The number of people with hypertrophyLV was significantly higher among patients of the 1st cluster (91.6 vs. 67.2 %, p < 0.001) due to eccentric hypertro-phy LV. Accordingly, concentric hypertrophy LV was more common among patients in the 2nd cluster (24.6 vs. 4.2 %at p < 0.01). Patients of the 1st cluster was characterized by a more severe course of heart failure. CONCLUSIONS In patients who suffered from CHD with stenotic atherosclerosis of the coronary arteries and wereexposed to radiation 30-35 years earlier, having normal body weight, there was a reduction in telomere. Hierarchicalcluster analysis proved to be a good tool that allows by the value of RTL and EDV/BSA to separate the group ofpatients with the most severe clinical course of CHD and LV systolic dysfunction among patients with the samepathology.

Abstract
UNLABELLED The objective of the study was to improve the biological dosimetry approach among patients with acute radiationsickness of various degrees based on the analysis of radiation-induced chromosome aberrations in peripheral bloodlymphocytes of the victims. MATERIALS AND METHODS The study was based on primary cytogenetic data obtained in May 1986 within examina-tion of the 30 clean-up workers («liquidators») having got stage I-III acute radiation sickness. Dose verificationwas performed using the cytogenetic dosimetry based on a culture of peripheral blood lymphocytes with metaphaseanalysis of chromosome aberrations. RESULTS A new method of evaluating the results of patients' cytogenetic examination at the beginning of specifictherapy has been developed. Procedure was performed using a model of multiple linear regression (complex of cyto-genetic parameters) and provided a satisfactory diagnostic level (featuring a compliance with initially definedclinical and laboratory diagnoses). Overall frequency of the aberrant cells and radiation markers increased in high-er disease stages. There was a trend of the frequency growth of chromatid-type aberrations with increasing of radi-ation burden. Adequacy of the proposed method based on the regression analysis of cytogenetic results was con-firmed through the preservation of group differences in estimates of disease stage in subjects with verified diagnosis. CONCLUSION Cytogenetic dosimetry in the scope of examination of persons exposed to ionizing radiation is an oblig-atory component of radiation sickness stage verification. The recommended method of cytogenetic data evaluationbefore and at the beginning of detoxification therapy provides a satisfactory level of diagnostics.

Abstract
BACKGROUND Radiation accidents at the Chornobyl Nuclear Power Plant (USSR, 1986) and Fukushima-1 (Japan,2011) have shown that global environmental contamination is an intervention in normal human life making nega-tive effect on population health. These accidents highlighted a number of statutory and regulatory both with me-dical and social problems for individuals, who returned voluntarily for permanent residence in the ChornobylExclusion Zone i.e. a radiation-hazardous area (they are named the «self-settlers»). OBJECTIVE generalization of experience in the settlement of normative-legal, ecological-dosimetric and medico-social life issues of population living in the Chornobyl NPP (ChNPP) Exclusion Zone («self-settlers»). OBJECT AND METHODS The chosen problem is complex, necessitating the generalization of radiation-hygienic, med-ical-biological, socio-economic, demographic and sociological research results obtained by the national and foreignauthors. A set of theoretical research and analysis of empirical data methods on the principles of interdisciplinaryinteraction was used; the systematic, legal, economic, medical-biological, demographic and retrospective-dosimet-ric approaches of research were applied. RESULTS It was shown that a part of population refused to evacuate or had returned for permanent residence to theradiation-hazardous lands after the ChNPP accident. In 1986-2009 the number of «self-settlers» ranged from 150to 2,000 in different years. In 2021 - the 101 people. Those were mainly people of working age, mostly females, single people or widows/widowers. Рrevious medical and dosimetric studies have shown that long-term residence inthe Exclusion Zone affects physical and mental health of «self-settlers» and causes atypical aging, includinginvolvement of the central nervous system. According to calculations, the average effective total radiation doseaccumulated by «self-settlers» for the first 3 years was 30 % of dose for the entire post-accident period, and thedose accumulated over 20 years was 54 % of the dose accumulated over 35 years. But the effective radiation dosesaccumulated in different periods after the accident differ significantly in residents of different Exclusion Zone settlements. This information needs further study in terms of the «radiation dose - health status» dependence. CONCLUSIONS The effective radiation doses accumulated in different periods after the accident differ significantlyin the residents of different Exclusion Zone settlements. Тhe average effective total radiation dose accumulated by«self-settlers» for the first 3 years was 30 % of the dose for the entire post-accident period, and the dose accumulated over 20 years was 54 % of the dose accumulated over 35 years.

Abstract
INTRODUCTION Persistent growth hormone hypersecretion can be observed in roughly 50% of patients operated for somatotroph adenomas, requiring additional treatments. Despite its proven antisecretory efficacy, the use of Gamma Knife radiosurgery (GK) is limited probably due to the lack of data on long-term side effects, including potential cognitive consequences. METHODS The LATe Effects of Radiosurgery in Acromegaly study was a cross-sectional exposed/unexposed non-randomized study. The primary objective was to determine the long-term neurocognitive effects of GK focusing on memory, executive functions, and calculation ability. Exposed patients had been treated by GK for acromegaly at least 5 years before inclusion. Unexposed patients (paired for age) had to be cured or controlled at last follow-up without any radiation technique. Patients of both groups were cured or controlled at the last follow-up. RESULTS Sixty-four patients were evaluated (27 exposed and 37 unexposed). Mean follow-up after GK was 13 ± 6 years (including 24 patients followed for at least 10 years). While up to 23.8% of the patients of the whole cohort presented at least one abnormal cognitive test, we did not observe any significant difference in neurocognitive function between both groups. During the follow-up, 11 patients presented at least one new pituitary deficiency (P = 0.009 for thyroid-stimulating hormone deficiency with a higher rate in exposed patients), two presented a stroke (1 in each group), and one presented a meningioma (12 years after GK). CONCLUSIONS While GK exposes patients to a well-known risk of pituitary deficiency, it does not seem to induce long-term cognitive consequences in patients treated for acromegaly.

Abstract
PURPOSE The contemporary management of early-stage Hodgkin lymphoma (ES-HL) involves balancing the risk of late adverse effects of radiotherapy against the increased risk of relapse if radiotherapy is omitted. This study provides information on the risk of radiation-related cardiovascular disease to help personalize the delivery of radiotherapy in ES-HL. METHODS We predicted 30-year absolute cardiovascular risk from chemotherapy and involved field radiotherapy in patients who were positron emission tomography (PET)-negative following three cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy within a UK randomized trial of PET-directed therapy for ES-HL. Cardiac and carotid radiation doses and chemotherapy exposure were combined with established dose-response relationships and population-based mortality and incidence rates. RESULTS Average mean heart dose was 4.0 Gy (range 0.1-24.0 Gy) and average bilateral common carotid artery dose was 21.5 Gy (range 0.6-38.1 Gy), based on individualized cardiovascular dosimetry for 144 PET-negative patients receiving involved field radiotherapy. The average predicted 30-year radiation-related absolute excess overall cardiovascular mortality was 0.56% (range 0.01%-6.79%; < 0.5% in 67% of patients and > 1% in 15%), whereas average predicted 30-year excess incidence was 6.24% (range 0.31%-31.09%; < 5% in 58% of patients and > 10% in 24%). For cardiac disease, the average predicted 30-year radiation-related absolute excess mortality was 0.42% (0.79% with mediastinal involvement and 0.05% without) and for stroke, it was 0.14%. CONCLUSION Predicted excess cardiovascular risk is small for most patients, so radiotherapy may provide net benefit. However, for a minority of patients receiving high doses of radiation to cardiovascular structures, it may be preferable to consider advanced radiotherapy techniques to reduce doses or to omit radiotherapy and accept the increased relapse risk. Individual assessment of cardiovascular and other risks before treatment would allow personalized decision making about radiotherapy in ES-HL.

Abstract
AIM The aim of this study was to review and report on radiation therapy injury claims lodged with the Accident Compensation Corporation (ACC) in New Zealand in the last decade. METHODS ACC's treatment injury database was used to identify injury claims decided between 1 July 2009 and 30 June 2019. The associated structured and unstructured data, including claim lodgement information and medical records, were reviewed. RESULTS Of 121,168 treatment injuries, only 975 (0.8%) were radiation therapy injury claims, with 519 claims accepted for cover. Most declined claims were considered "ordinary consequences of treatment" rather than treatment injuries. Of the 519 accepted claims, ACC classified 21 as fatal and eight as serious, which indicates a need for lifelong ACC support. Injuries correlated with the age and gender of the most common cancers treated with radiation therapy in New Zealand. More treatment injury claims were submitted and accepted for New Zealand European patients compared with Māori and Pasifika patients. CONCLUSION Radiation therapy injury claims make up a very small proportion of the total number of ACC treatment injury claims. A better understanding of the claim process may assist injured individuals better by improving appropriate claim lodgement and claim acceptance rates.

Abstract
BACKGROUND Radiation induced enteropathy is a common complication of radiotherapy for pelvic tumors and adversely affects patient quality of life. Probiotics are thought to restore bowel microflora to optimal levels and reinforce intestinal barrier capacity. Although probiotics are effective in the treatment of radiation induced enteropathy, less is known about their efficacy to prevent radiation induced enteropathy. METHODS This double-blind randomized placebo-controlled study will investigate the efficacy of probiotics to prevent radiation-induced enteropathy in patients with gynecologic or urologic cancer who received pelvic radiotherapy. The study is designed to enroll 248 eligible patients, who will be randomized 1:1 to a probiotic or placebo group. Toxicities will be evaluated using Common Terminology Criteria for Adverse Events (CTCAE) v5.0. DISCUSSION The primary aim of this study is to provide high level evidence for the ability of probiotics to prevent acute radiation induced enteropathy. The secondary aims are to determine the effects of probiotics on the incidence of chronic radiation induced enteropathy and the safety of probiotics in patients with gynecologic or urologic cancer.

Abstract
OBJECTIVES The present multicenter Phase II study evaluated the rate of late grade ≥2 gastrointestinal (GI) toxicities at 3 years, after hypofractionated radiotherapy (HFR) of prostate cancer with injection of hyaluronic acid (HA) between the prostate and the rectum. METHODS Between 2010 and 2013, 36 patients with low- or intermediate-risk prostate cancer were treated by HFR/IMRT-IGRT. 20 fractions of 3.1 Gy were delivered, 5 days per week for a total dose of 62 Gy. A transperineal injection of 10cc of HA was performed between the rectum and the prostate. Late toxicities were evaluated between 3 and 36 months after the end of treatment (CTCAE v4). RESULTS Median pretreatment prostate-specific antigen was 8 ng ml-1. Among the 36 included patients, 2 were not evaluated because they withdrew the study in the first 3 months of follow-up, and 4 withdrew between 3 and 36 months, the per protocol population was therefore composed.Late grade ≥2 GI toxicities occurred in 4 (12%) patients with 3 (9%) Grade 2 rectal bleedings and one diarrhoea. Therefore, the inefficacy hypothesis following Fleming one-stage design cannot be rejected. None of the patients experienced late Grade 3-4 toxicities. Among the 30 patients completing the 36 months' visit, none still had a grade ≥2 GI toxicity. Late grade ≥2 genitourinary (GU) toxicities occurred in 14 (41%) patients. The most frequent toxicities were dysuria and pollakiuria. Four patients still experienced a grade ≥2 GU toxicity at 36 months.The biochemical relapse rate (nadir +2 ng ml-1) was 6% (2 patients). Overall, HA was very well tolerated with no pain or discomfort. CONCLUSION Despite the inefficacy of HA injection was not rejected, we observed the absence of Grade 3 or 4 rectal toxicity as well as a rate of Grade 2 rectal bleeding below 10% at 36 months of follow-up. Late urinary toxicities are the most frequent but the rate decreases largely at 3 years. ADVANCES IN KNOWLEDGE With an injection of HA, hypofractionated irradiation in 4 weeks is well tolerated with no Grade 3 or 4 GI toxicity and a rate of Grade 2 rectal bleeding below 10% at 36 months of follow-up.

Abstract
Charged-particle therapy (CPT) such as proton beam therapy (PBT) and carbon-ion radiotherapy (CIRT) exhibit substantial physical and biological advantages compared to conventional photon radiotherapy. As it can reduce the amount of radiation irradiated in the normal organ, CPT has been mainly applied to pediatric cancer and radioresistent tumors in the eloquent area. Although there is a possibility of greater benefits, high set-up cost and dearth of high level of clinical evidence hinder wide applications of CPT. This review aims to present recent clinical results of PBT and CIRT in selected diseases focusing on possible indications of CPT. We also discussed how clinical studies are conducted to increase the number of patients who can benefit from CPT despite its high cost.

Abstract
BACKGROUND Nutritional complications in patients with locally advanced head and neck cancer (LA-HNC) treated by concurrent chemoradiotherapy (CCRT) often lead to placement of a prophylactic gastrostomy (PG) tube, while indication lacks harmonization. Our aim was to explore the current PG tube utilization among Belgian radiation oncology centers. METHODS A survey was distributed to all 24 Belgian Radiation oncology departments, with questions about the number of patient treated per year, whether the PG indication is discussed at the multidisciplinary board, placement technique, time of starting nutrition and removal, its impact on swallowing function and importance of clinical factors. For the latter Relative Importance and Discordance Indexes were calculated to describe the ranking and agreement. RESULTS All 24 centers submitted the questionnaire. Twenty three treat more than 20 head and neck (HNC) patients per year, while four (1 in 21-50; 3 in 51-100) are not discussing the gastrostomy tube indication at the multidisciplinary board. For the latter, endoscopic placement (68%) is the dominant technique, followed by the radiologic (16%) and laparoscopic (16%) methods. Seventy-five percent start the enteral nutrition when clinically indicated, 17% immediately and 8% from the start of radiotherapy. Majority of specialists (19/24) keep the gastrostomy tube until the patient assume an adequate oral feeding. Fifteen centres are considering PG decrease swallowing function. Regarding factors and their importance in the decision for the PG, foreseen irradiated volume reached highest importance, followed by 'anatomical site', 'patients' choice' and 'postoperative versus definitive' and 'local expertise', with decreasing importance respectively. Disagreement indexes showed moderate variation. CONCLUSIONS The use of a PG tube for LAHNC patients treated by CCRT shows disparity at national level. Prospective studies are needed to ensure proper indication of this supportive measure.

Abstract
IMPORTANCE To promptly recognize and manage cardiovascular (CV) risk factors before, during, and after cancer treatment, decreasing the risk of cancer therapy-related cardiac dysfunction is crucial. After recent advances in breast cancer treatment, mortality rates from cancer have decreased, and the prevalence of survivors with a potentially higher CV disease risk has increased. Cardiovascular risks might be associated with the multimodal approach, including systemic therapies and breast radiotherapy (RT). OBSERVATIONS The heart disease risk seems to be higher in patients with tumors in the left breast, when other classic CV risk factors are present, and when adjunctive anthracycline-based chemotherapy is administered, suggesting a synergistic association. Respiratory control as well as modern RT techniques and their possible further refinement may decrease the prevalence and severity of radiation-induced heart disease. Several pharmacological cardioprevention strategies for decreasing cardiac toxic effects have been identified in several guidelines. However, further research is needed to ascertain the feasibility of these strategies in routine practice. CONCLUSIONS AND RELEVANCE This review found that evidence-based recommendations are lacking on the modalities for and intensity of heart disease screening, surveillance of patients after RT, and treatment of these patients. A multidisciplinary and multimodal approach is crucial to guide optimal management.

Abstract
The review presents the results of a retrospective analysis of early markers of chronic radiation syndrome (CRS) in residents of the Techa riverside settlements. Mean values of postnatal red bone marrow doses calculated with the Techa River Dosimetry System-2016D were 698.8 ± 18.2 mGy, and maximum values reached 3 603.9 mGy. The clinical picture of the initial CRS stage was characterized by a set of non-specific functional changes that included not only hematopoietic but also immune, neurological, endocrine, and visceral disorders. CRS signs developed in a certain sequence. The earliest CRS signs were: increase of olfactory and taste thresholds, decrease of sensitivity to vibration and changes of systemic immunity. These were registered prior to hematopoietic changes typical of CRS. All initial organ changes related to CRS were functional in nature, mild or moderate, and transient. Early changes induced by chronic exposure in nervous, immune, and endocrine systems permit to consider CRS at early stages as a stereotype dysregulation pathology primarily based on radiation-induced disorders in regulatory systems. Disorders of circulatory, digestive, and other organs at early stages of CRS are secondary and their function restores spontaneously when the exposure stops. If exposure is continuous at doses sufficient for development of morphological tissue changes (dystrophy, fibrosis, hypoplasia and others), the CRS course becomes progressive and irreversible. The paper also describes the specific clinical manifestations of early stage of CRS in children.

Abstract
Radiation overexposure is common in chest X-ray (CXRs) of pediatric patients. However, overexposure may reveal incidental findings that can help to guide patient management or warrant quality improvement.To assess the prevalence of overexposure in CXRs in pediatric intensive care unit (PICU); and identify the incidental findings within overexposed areas, we conducted a retrospective cohort study of children who were admitted to PICU. Two independent evaluators reviewed patient's charts and digital CXRs according to the American College of Radiology standards; to evaluate overexposure of the anatomical parameters and incidental findings.A total of 400 CXRs of 85 patients were reviewed. The mean number of CXRs per patient was 4.7. Almost all (99.75%) CXRs met the criteria for overexposure, with the most common being upper abdomen (99.2%), upper limbs (97%) and neck (95.7%). In addition, 43% of these X-rays were cropped by the radiology technician to appear within the requested perimeter. There was a significant association between field cropping and overexposure (t-test: t = 9.8, P < .001). Incidental findings were seen in 41.5% of the radiographs; with the most common being gaseous abdominal distension (73.1%), low-positioned nasogastric tube (24.6%), and constipation (10.3%).Anatomical overexposure in routine CXRs remains high and raises a concern in PICU practice. Appropriate collimation of the X-ray beam, rather than electronically cropping the image, is highly recommended to minimize hiding incidental findings in the cropped-out areas. Redefining the anatomic boundaries of CXR in critically ill infants and children may need further studies and consideration. Quality improvement initiatives to minimize radiation overexposure in PICU are recommended, especially in younger children and those with more severe illness upon PICU admission.

Abstract
PURPOSE There are well-known correlations between high and moderate doses (>0.5 Gy) of ionizing radiation exposure and circulatory system damage, also between radiation and posterior subcapsular cataract. At lower dose correlations with circulatory disease are emerging in the Japanese atomic bomb survivors and in some occupationally exposed groups, and are still to some extent controversial. Heterogeneity in excess relative risks per unit dose in epidemiological studies at low (<0.1 Gy) and at low-moderate (>0.1 Gy, <0.5 Gy) doses may result from confounding and other types of bias, and effect modification by established risk factors. There is also accumulating evidence of excess cataract risks at lower dose and low dose rate in various cohorts. Other ocular endpoints, specifically glaucoma and macular degeneration have been little studied. In this paper, we review recent epidemiological findings, and also discuss some of the underlying radiobiology of these conditions. We briefly review some other types of mainly neurological nonmalignant disease in relation to radiation exposure. CONCLUSIONS We document statistically significant excess risk of the major types of circulatory disease, specifically ischemic heart disease and stroke, in moderate- or low-dose exposed groups, with some not altogether consistent evidence suggesting dose-response non-linearity, particularly for stroke. However, the patterns of risk reported are not straightforward. We also document evidence of excess risks at lower doses/dose-rates of posterior subcapsular and cortical cataract in the Chernobyl liquidators, US Radiologic Technologists and Russian Mayak nuclear workers, with fundamentally linear dose-response. Nuclear cataracts are less radiogenic. For other ocular endpoints, specifically glaucoma and macular degeneration there is very little evidence of effects at low doses; radiation-associated glaucoma has been documented only for doses >5 Gy, and so has the characteristics of a tissue reaction. There is some evidence of neurological detriment following low-moderate dose (∼0.1-0.2 Gy) radiation exposure in utero or in early childhood.

Abstract
Importance The adoption of alternative fractionated radiotherapy regimens for the treatment of patients with cancer and comorbid collagen vascular disease (CVD) is controversial among oncologists because of concerns about potentially severe toxic effects; however, the association between fractionated radiotherapy and toxic effects in the modern era has not been well studied. Objective To compare acute and late toxic effects among patients with cancer and comorbid CVD who received dose-fractionated radiotherapy. Design, Setting, and Participants This retrospective cohort study examined 197 adult patients with cancer and CVD who received radiotherapy at a single-institution tertiary academic center over a 12-year period (February 1, 2007, to April 30, 2019), with a median follow-up of 23 months (range, 0-108 months). Data were analyzed from February 1 to August 31, 2020. Exposures Three dose-fractionated radiotherapy regimens: conventional fractionation (CF; ≤2 Gy per fraction), moderate hypofractionation (MH; >2 Gy to <5 Gy per fraction), and ultrahypofractionation (UH; ≥5 Gy per fraction). Main Outcomes and Measures The main outcomes were the incidence and severity of acute and late radiotherapy-associated toxic effects, which were assessed separately by dose-fractionation regimen. Toxic effects occurring within 90 days after radiotherapy completion were considered acute, and toxic effects occurring after that 90-day period were considered late. Secondary goals were to identify covariates associated with toxic effects and to characterize the incidence of CVD symptom flares (defined as worsening clinical symptoms and/or worsening results [transient or permanent] on associated blood tests compared with baseline, as documented by managing physicians) after radiotherapy. Results Of 197 patients with cancer and comorbid CVD (mean [SD] age, 69 [12] years; 134 women [68.0%]; and 149 White participants [75.6%]), 80 patients (40.6%) received CF radiotherapy, 55 patients (27.9%) received MH radiotherapy, and 62 patients (31.5%) received UH radiotherapy. The most common CVD diagnoses were rheumatoid arthritis (74 patients [37.6%]), psoriasis (54 patients [27.4%]), systemic lupus erythematosus (34 patients [17.3%]), and scleroderma (8 patients [4.1%]). The most common radiotherapy sites were the breast (48 patients [24.4%]), thorax (25 patients [12.7%]), central nervous system (24 patients [12.2%]), and prostate (23 patients [11.7%]). Data on acute toxic effects were available for 188 patients (95.4%) and missing for 9 patients (4.6%). Data on late toxic effects were available for 142 patients (72.1%) and missing for 55 patients (27.9%). Over 12 years, the unadjusted incidences of severe acute toxic effects associated with CF, MH, and UH radiotherapy were 5.4% (95% CI, 0.3%-10.5%), 7.4% (95% CI, 0.4%-14.4%), and 1.7% (95% CI, 0%-5.0%), respectively. The incidences of severe late toxic effects associated with CF, MH, and UH radiotherapy were 8.3% (95% CI, 1.3%-15.3%), 0%, and 2.2% (95% CI, 0%-6.4%), respectively. No significant associations were found between severe acute or late toxic effects by dose fractionation regimen. In the multivariable analysis, MH radiotherapy was associated with a lower likelihood of developing late toxic effects (odds ratio [OR], 0.21; 95% CI, 0.05-0.83; P = .03) compared with CF radiotherapy. Those who received UH radiotherapy had a lower likelihood of experiencing late toxic effects (OR, 0.22; 95% CI, 0.04-1.21; P = .08). A total of 19 of 80 patients (23.8%), 15 of 55 patients (27.3%), and 10 of 62 patients (16.1%) experienced CVD symptom flares after receiving CF, MH, and UH radiotherapy, respectively (P = .33). Conclusions and Relevance In this study, the incidences of unadjusted severe toxic effects over 12 years were less than 10% and were not significantly associated with dose fractionation. When clinically indicated, patients with cancer and comorbid CVD may not require immediate exclusion from the receipt of currently used hypofractionated radiotherapy regimens.

Abstract
The last decades have seen increased concern about the possible effects of low to moderate doses of ionizing radiation (IR) exposure on cognitive function. An interdisciplinary group of experts (biologists, epidemiologists, dosimetrists and clinicians) in this field gathered together in the framework of the European MELODI workshop on non-cancer effects of IR to summarise the state of knowledge on the topic and elaborate research recommendations for future studies in this area. Overall, there is evidence of cognitive effects from low IR doses both from biology and epidemiology, though a better characterization of effects and understanding of mechanisms is needed. There is a need to better describe the specific cognitive function or diseases that may be affected by radiation exposure. Such cognitive deficit characterization should consider the human life span, as effects might differ with age at exposure and at outcome assessment. Measurements of biomarkers, including imaging, will likely help our understanding on the mechanism of cognitive-related radiation induced deficit. The identification of loci of individual genetic susceptibility and the study of gene expression may help identify individuals at higher risk. The mechanisms behind the radiation induced cognitive effects are not clear and are likely to involve several biological pathways and different cell types. Well conducted research in large epidemiological cohorts and experimental studies in appropriate animal models are needed to improve the understanding of radiation-induced cognitive effects. Results may then be translated into recommendations for clinical radiation oncology and imaging decision making processes.

Abstract
In Japan, a robotic-assisted PCI (R-PCI) system, the CorPath GRX System (Corindus Inc.), has been approved for clinical use in 2018, which is the first introduction of R-PCI into Japan. In this study, the clinical performance of the R-PCI system in the initial year at Kurume University Hospital was evaluated comparing with conventional manual PCI (M-PCI). A total of 30 R-PCI and 77 M-PCI procedures performed between April 2019 and March 2020, were retrospectively included. The primary outcome was the rate of clinical success defined as < 30% residual stenosis without in-hospital major adverse cardiovascular events (MACE). The secondary outcomes were fluoroscopy time, dose area product (DAP), amount of radiation exposure to operators and assistants, procedural time, and contrast volume. Propensity-matching technique was used to match each R-PCI lesion to the nearest M-PCI lesion without replacement. After propensity score matching, 30 R-PCI procedures in 28 patients and 37 M-PCI procedures in 35 patients were analyzed. Clinical success rate with R-PCI was favorable and comparable to M-PCI (93.3 vs. 94.6%, p = 0.97), without any in-hospital MACE. The operator radiation exposure was significantly lower in R-PCI (0 vs. 24.5 µSV, p < 0.0001). Radiation exposure to the patients was tended to be reduced by R-PCI (DAP: 77.6 vs. 100.2 Gycm2, p = 0.07). There were no statistically significant differences in radiation exposure to the assistant, fluoroscopy time, procedural time and contrast volume between the two groups (radiation exposure to the assistant: 10.5 vs. 10.0 µSV, p = 0.64, fluoroscopy time: 27.5 vs. 30.1 min, p = 0.55, procedural time: 72.4 vs. 61.6 min, p = 0.23, and contrast volume: 93.2 vs. 102.0 ml, p = 0.36). R-PCI in selected patients demonstrated favorable clinical outcomes with dramatical reduction of radiation exposure to operators.

Abstract
Purpose To investigate men’s experiences of receiving external-beam radiotherapy (EBRT) with neoadjuvant Androgen Deprivation Therapy (ADT) for localized prostate cancer (LPCa) in the ProtecT trial. Methods A longitudinal qualitative interview study was embedded in the ProtecT RCT. Sixteen men with clinically LPCa who underwent EBRT in ProtecT were purposively sampled to include a range of socio-demographic and clinical characteristics. They participated in serial in-depth qualitative interviews for up to 8 years post-treatment, exploring experiences of treatment and its side effects over time. Results Men experienced bowel, sexual, and urinary side effects, mostly in the short term but some persisted and were bothersome. Most men downplayed the impacts, voicing expectations of age-related decline, and normalizing these changes. There was some reticence to seek help, with men prioritizing their relationships and overall health and well-being over returning to pretreatment levels of function. Some unmet needs with regard to information about treatment schedules and side effects were reported, particularly among men with continuing functional symptoms. Conclusions These findings reinforce the importance of providing universal clear, concise, and timely information and supportive resources in the short term, and more targeted and detailed information and care in the longer term to maintain and improve treatment experiences for men undergoing EBRT.

Abstract
Risks to health are the prime consideration in all human situations of ionizing radiation exposure and therefore of relevance to radiation protection in all occupational, medical, and public exposure situations. Over the past few decades, advances in therapeutic strategies have led to significant improvements in cancer survival rates. However, a wide range of long-term complications have been reported in cancer survivors, in particular circulatory diseases and their major risk factors, metabolic diseases. However, at lower levels of exposure, the evidence is less clear. Under real-life exposure scenarios, including radiotherapy, radiation effects in the whole organism will be determined mainly by the response of normal tissues receiving relatively low doses, and will be mediated and moderated by systemic effects. Therefore, there is an urgent need for further research on the impact of low-dose radiation. In this article, we review radiation-associated risks of circulatory and metabolic diseases in clinical, occupational or environmental exposure situations, addressing epidemiological, biological, risk modelling, and systems biology aspects, highlight the gaps in knowledge and discuss future directions to address these gaps.

Radiation-induced lens opacities: Epidemiological, clinical and experimental evidence, methodological issues, research gaps and strategy. Environ Int 2021; 146:106213.

Abstract
In 2011, the International Commission on Radiological Protection (ICRP) recommended reducing the occupational equivalent dose limit for the lens of the eye from 150 mSv/year to 20 mSv/year, averaged over five years, with no single year exceeding 50 mSv. With this recommendation, several important assumptions were made, such as lack of dose rate effect, classification of cataracts as a tissue reaction with a dose threshold at 0.5 Gy, and progression of minor opacities into vision-impairing cataracts. However, although new dose thresholds and occupational dose limits have been set for radiation-induced cataract, ICRP clearly states that the recommendations are chiefly based on epidemiological evidence because there are a very small number of studies that provide explicit biological and mechanistic evidence at doses under 2 Gy. Since the release of the 2011 ICRP statement, the Multidisciplinary European Low Dose Initiative (MELODI) supported in April 2019 a scientific workshop that aimed to review epidemiological, clinical and biological evidence for radiation-induced cataracts. The purpose of this article is to present and discuss recent related epidemiological and clinical studies, ophthalmic examination techniques, biological and mechanistic knowledge, and to identify research gaps, towards the implementation of a research strategy for future studies on radiation-induced lens opacities. The authors recommend particularly to study the effect of ionizing radiation on the lens in the context of the wider, systemic effects, including in the retina, brain and other organs, and as such cataract is recommended to be studied as part of larger scale programs focused on multiple radiation health effects.
