Abstract
This study focused on a novel strategy that combines deep learning and radiomics to predict epidermal growth factor receptor (EGFR) mutations in patients with non-small cell lung cancer (NSCLC) using computed tomography (CT). A total of 1280 patients with NSCLC who underwent contrast-enhanced CT scans and EGFR mutation testing before treatment were selected for the final study. Regions of interest were segmented from the CT images to extract radiomics features and obtain tumor images. These tumor images were input into a convolutional neural network model to extract 512 image features, which were combined with radiographic features and clinical data to predict the EGFR mutation. The generalization performance of the model was evaluated using external institutional data. The internal and external datasets contained 324 and 130 EGFR mutants, respectively. Sex, height, weight, smoking history, and clinical stage were significantly different between the EGFR-mutant patient groups. The EGFR mutations were predicted by combining the radiomics and clinical features, and an external validation dataset yielded an area under the curve (AUC) value of 0.7038. The model utilized 1280 tumor images, radiomics features, and clinical characteristics as input data and exhibited an AUC of approximately 0.81 and 0.78 during the primary cohort and external validation, respectively. These results indicate the feasibility of integrating radiomics analysis with deep learning for predicting EGFR mutations. CT-image-based genetic testing is a simple EGFR mutation prediction method, which can improve the prognosis of NSCLC patients and help establish personalized treatment strategies.

Abstract
168 Background: We developed a deep learning model to predict pathological response based on magnetic 3D resonance imaging in rectal cancer. Methods: A total of 242 patients with locally advanced rectal cancer who received preoperative chemoradiotherapy followed by surgical resection were collected from single center. Surgical resection was performed at 6 to 8 weeks after the completion of preoperative CRT. Achieving pathogic complete response (pCR) was defined as complete absence of any tumour cells, in both the primary site and the dissected lymph node in surgical specimens. Based on pre-chemoradiotherapy T1-weighted axial 3D MR images, deep learning models were developed to predict pCR, respectively. Results: We analyzed 32,000 MRI images and involved several radiation oncologists in segmenation and classification. To calculate the probability of pCR using various convolutional neural network (CNN) architectures, several deep learning models were developed. The data input to the deep learning model was 3D MRI image, clinical data, and MRI metadata. Among 242 patients, 50 (20.7%) had evidence of pCR. The best model was developed based on SeResNet using transfer learning by MONA framework. The deep learning model showed an area under the receiver operating characteristic curve, sensitivity, specificity, and accuracy of 0.926, 0.831, 0.921, and 90.2% for predicting pCR. Conclusions: The pre-chemoradiotherapy T1-weighted 3D MR image-based deep learning model showed acceptable performance in predicting pCR in patients with rectal cancer.[Table: see text]

Abstract
PURPOSE We developed a comprehensive return to work (RTW) intervention covering physical, psycho-social and practical issues for patients newly diagnosed and evaluated its efficacy in terms of RTW. Materials and Methods A multi-center randomized controlled trial was done to evaluate the efficacy of the intervention conducted at two university-based cancer centers in Korea. The intervention program comprised educational material at diagnosis, a face-to-face educational session at completion of active treatment, and three individualized telephone counseling sessions. The control group received other education at enrollment. RESULTS At 1-month post-intervention (T2), the intervention group was more likely to be working compared to the control group after controlling working status at diagnosis (65.4% vs. 55.9%, p=0.037). Among patients who did not work at baseline, the intervention group was 1.99-times more likely to be working at T2. The mean of knowledge score was higher in the intervention group compared to the control group (7.4 vs. 6.8, p=0.029). At the 1-year follow-up, the intervention group was 65% (95% confidence interval, 0.78 to 3.48) more likely to have higher odds for having work. CONCLUSION The intervention improved work-related knowledge and was effective in facilitating cancer patients' RTW.

Abstract
Background: This study aimed to investigate the impact of absolute lymphocyte count (ALC) on clinical outcomes in patients treated with adjuvant RT with or without chemotherapy for pancreatic adenocarcinoma. Methods: From 2001 to 2015, 68 patients underwent curative surgery followed by adjuvant RT. Chemotherapy was administered concurrently or sequentially with RT. We analyzed the clinical impact of the initial ALC level on locoregional recurrence-free survival (LRRFS), distant metastasis-free survival (DMFS), and overall survival (OS). Results: With a median follow-up of 13.7 months (range: 3.1–61.3), the 3 year OS, LRRFS, and DMFS are 25.4%, 40.0%, and 26.6%, respectively. The OS and LRRFS of the high initial ALC group (≥ 1540 × 106/L) are significantly higher than that of the group with lower initial ALC (3 year OS: 32.6% vs. 18.6%, p = 0.036; 3 year LRRFS: 53.5% vs. 27.0%, p = 0.031). In multivariable analyses, initial ALC level is the significant prognostic factor affecting LRRFS (HR = 0.457, p = 0.028) and OS (HR = 0.473, p = 0.026). Conclusions: Initial ALC could have potential prognostic significance in patients with pancreatic adenocarcinoma receiving adjuvant RT with or without chemotherapy. Further studies are warranted to investigate the role of adjuvant RT, considering the initial ALC.

Abstract
BACKGROUND/AIMS The study investigated the incidence of thromboembolic events (TEE) in head and neck (H&N) cancer patients who received concurrent chemoradiotherapy (CCRT) with cisplatin, and analyzed the factors affecting TEE occurrence. METHODS Two hundred and fifty-seven patients who started CCRT with cisplatin for H&N cancer from January 2005 to December 2019 were analyzed. RESULTS TEE occurred in five patients, an incidence rate of 1.9%. The 2-, 4-, and 6-month cumulative incidences of TEE were 0.8%, 1.6%, and 1.9%, respectively. Khorana score was the only factor associated with TEE occurrence (p = 0.010). CONCLUSION The incidence of TEE in H&N cancer patients who underwent CCRT with cisplatin was relatively low when compared to other types of cancer. However, patients with a high Khorana score require more careful surveillance for possible TEE occurrence.

Abstract
In this study, we developed a deep learning model to identify patients with tongue cancer based on a validated dataset comprising oral endoscopic images. We retrospectively constructed a dataset of 12,400 verified endoscopic images from five university hospitals in South Korea, collected between 2010 and 2020 with the participation of otolaryngologists. To calculate the probability of malignancy using various convolutional neural network (CNN) architectures, several deep learning models were developed. Of the 12,400 total images, 5576 images related to the tongue were extracted. The CNN models showed a mean area under the receiver operating characteristic curve (AUROC) of 0.845 and a mean area under the precision-recall curve (AUPRC) of 0.892. The results indicate that the best model was DenseNet169 (AUROC 0.895 and AUPRC 0.918). The deep learning model, general physicians, and oncology specialists had sensitivities of 81.1%, 77.3%, and 91.7%; specificities of 86.8%, 75.0%, and 90.9%; and accuracies of 84.7%, 75.9%, and 91.2%, respectively. Meanwhile, fair agreement between the oncologist and the developed model was shown for cancer diagnosis (kappa value = 0.685). The deep learning model developed based on the verified endoscopic image dataset showed acceptable performance in tongue cancer diagnosis.

Abstract
Objective Children with acute lymphoblastic leukemia (ALL) may be at increased risk of psychiatric disorders. This study analyzed the incidence of psychiatric disorders in children with ALL in South Korea. Methods Using nationwide claims data for January 2009 to March 2016, we identified three major psychiatric disorders (depression, anxiety and stress/adjustment disorder) among children diagnosed with ALL. We analyzed the incidence of psychiatric disorders before and after ALL diagnosis. Results Overall, 2160 children diagnosed with ALL were identified. Seventy-five children (3.5%) were diagnosed with at least one major psychiatric disorder from 1 year before ALL diagnosis to the last follow-up point (range: 42.5–111.5 months). Of these, 70 (93.3%) patients were identified after ALL diagnosis, with the incidence peaking 1 year after ALL diagnosis. Depression, anxiety and stress/adjustment disorders were diagnosed in 30 (1.4%), 15 (0.7%) and 30 (1.4%) patients, respectively. Conclusions Among pediatric patients with ALL, most psychiatric disorders were identified after the diagnosis of leukemia, and psychiatric disorder incidence differed according to patient age and time since ALL diagnosis. Timely screening for and proper management of mental disorders are needed during all stages of ALL treatment.

Abstract
OBJECTIVE Hyperlipidemia is a risk factor of cerebrovascular disease (CVD). However, the relationship between CVD and cholesterol variability is less clear. This study assesses the relationship between cholesterol change and CVD risk. PATIENTS AND METHODS We reviewed 480,830 people from 20 to 99 years with 2 health check-ups from 2002 to 2015 from the Korean National Health Insurance (KNHI) database. People's baseline and follow-up cholesterol levels were classified into low (<180 mg/dL), moderate (≥180 mg/dL and <240 mg/dL), and high (≥240 mg/dL). Participants were divided into 9 groups (low-to-low, low-to-moderate, low-to-high, moderate-to-low, moderate-to-moderate, moderate-to-high, high-to-low, high-to-moderate, high-to-high). RESULTS Low to high cholesterol level is associated with hemorrhagic stroke (aHR1 = 1.59; 95% CI 1.12-2.28 and aHR2 = 1.56; 95% CI 1.07-2.25). Low to moderate/high cholesterol level is associated with ischemic stroke and occlusion/stenosis (for low to moderate, aHR1 = 1.11; 95% CI 1.04-1.17 and aHR2 = 1.14; 95% CI 1.07-1.21 for ischemic stroke and aHR1 = 1.18; 95% CI 1.07-1.29 and aHR2 = 1.20; 95% CI 1.08-1.32 for occlusion/stenosis, for low to high, aHR1 = 1.42; 95% CI 1.20-1.67 and aHR2 = 1.28; 95% CI 1.08-1.52 for ischemic stroke and aHR1 = 1.86; 95% CI 1.46-2.36 and aHR2= 1.74; 95% CI 1.36-2.23 for occlusion/stenosis). Moderate to high cholesterol level is associated with ischemic stroke and occlusion/stenosis (for ischemic stroke, aHR1 = 1.12; 95% CI 1.05-1.20 and aHR2 = 1.10; 95% CI 1.03-1.17, for occlusion/stenosis, aHR1 = 1.21; 95% CI 1.10-1.33 and aHR2 = 1.19; 95% CI 1.08-1.32). Moderate to low cholesterol level is associated with ischemic and hemorrhagic stroke and occlusion/stenosis (for ischemic, aHR1 = 1.15; 95% CI 1.09-1.21, for hemorrhagic, aHR1 = 1.14; 95% CI 1.01-1.28, for occlusion/stenosis, aHR1 = 1.14; 95% CI 1.05-1.23). High to low cholesterol level is associated with ischemic stroke and occlusion/stenosis (for ischemic stroke, aHR1 = 1.51; 95% CI 1.33-1.71 and aHR2 = 1.20; 95% CI 1.05-1.36, for occlusion/stenosis, aHR1 = 1.50; 95% CI 1.24-1.81). CONCLUSIONS Our study shows that cholesterol changes, especially larger changes, lead to an increase in CVD, which demonstrates that cholesterol variability may increase CVD.

Abstract
The purpose of this study was to investigate the impact of the coronavirus disease 2019 (COVID-19) pandemic on patients undergoing radiotherapy by comparing the patterns of unplanned radiotherapy interruption before and after the COVID-19 pandemic. We enrolled patients who received their first dose of radiotherapy for breast cancer between January 28 and July 31, 2019 and between January 28, 2020, and July 31, 2020. We compared the radiotherapy interruption patterns in 2019 with those in 2020 to analyze the impact of the COVID-19 pandemic on treatment interruption. Between January 28 and July 31, 2019, 287 patients with breast cancer received radiotherapy. Among them, 19 patients (6.6%) experienced treatment interruption; the reasons for treatment interruption were radiotherapy-related side effects (10 patients, 52.6%), other medical reasons (three patients, 15.8%), and personal reasons (six patients, 31.6%). Between January 28 and July 31, 2020, 279 patients with breast cancer received radiotherapy. Among them, 23 patients (8.2%) experienced treatment interruption; the reasons for treatment interruption were radiotherapy-related side effects (eight patients, 35%) and COVID-19 screening clinic-related reasons (six patients, 26.1%). Among the six patients with screening clinic-related causes of radiotherapy interruption, five had asymptomatic fever and one had mild cold-like symptoms. The duration of treatment interruption was longer in patients with screening clinic-related interruptions than in those with interruptions because of other causes (p = 0.019). Multivariate analysis showed that cancer stage and radiotherapy volume did not significantly affect treatment interruption. The radiotherapy of certain patients was suspended despite the lack of a confirmed COVID-19 diagnosis. Precise and systematic criteria for the management of patients with suspected COVID-19 are needed, and the opinion of radiation oncologist in charge of the patient must also be considered.

Abstract
Simple Summary The paradigm shift from cytotoxic chemotherapy to molecular targeted therapy dramatically improved the survival and quality of life of cancer patients. In radio-oncological aspects, there also was a paradigm shift from whole-brain radiotherapy to localized radiotherapy including stereotactic radiosurgery. This retrospective study analyzed 124 consecutive patients who had undergone surgical resection of brain metastases. We found targeted therapies to improve overall survival and distant control with decreased incidence of leptomeningeal metastasis. Our data suggest that localized radiotherapy is sufficient after resection of brain metastases when systemic targeted therapy is available. Abstract Whether targeted therapy (TT) and radiotherapy impact survival after resection of brain metastases (BM) is unknown. The purpose of this study was to analyze the factors affecting overall survival (OS), local control (LC), distant control (DC), and leptomeningeal metastases (LMM) in patients who had undergone resection of BM. We retrospectively analyzed 124 consecutive patients who had undergone resection of BM between 2004 and 2020. Patient information about age, sex, Karnofsky Performance Scale (KPS), origin of cancer, synchronicity, tumor size, status of primary cancer, use of TT, extent of resection, and postoperative radiotherapy was collected. Radiation therapy was categorized into whole-brain radiotherapy (WBRT), localized radiotherapy (local brain radiotherapy or stereotactic radiosurgery (LBRT/SRS)), and no radiation. We identified factors that affect OS, LC, DC, and LMM. In multivariable analysis, significant factors for OS were higher KPS score (≥90) (HR 0.53, p = 0.011), use of TT (HR 0.43, p = 0.001), controlled primary disease (HR 0.63, p = 0.047), and single BM (HR 0.55, p = 0.016). Significant factors for LC were gross total resection (HR 0.29, p = 0.014) and origin of cancer (p = 0.041). Both WBRT and LBRT/SRS showed superior LC than no radiation (HR 0.32, p = 0.034 and HR 0.38, p = 0.018, respectively). Significant factors for DC were use of TT (HR 0.54, p = 0.022) and single BM (HR 0.47, p = 0.004). Reduced incidence of LMM was associated with use of TT (HR 0.42, p = 0.038), synchronicity (HR 0.25, p = 0.028), and controlled primary cancer (HR 0.44, p = 0.047). TT was associated with prolonged OS, improved DC, and reduced LMM in resected BM patients. WBRT and LBRT/SRS showed similar benefits on LC. Considering the extended survival of cancer patients and the long-term effect of WBRT on cognitive function, LBRT/SRS appears to be a good option after resection of BM.

Abstract
Delayed wound healing in heavily irradiated areas is a serious clinical complication that makes widespread therapeutic use of radiation difficult. Efficient treatment strategies are urgently required for addressing radiation-induced wound failure. Herein, we applied liquid-type nonthermal atmospheric plasma (LTP) to a silk-fibrin (SF) composite gel to investigate whether controlled release of LTP from SF hydrogel not only induced favorable cellular events in an irradiated wound bed but also modulated the SF hydrogel microstructure itself, eventually facilitating the development of a regenerative microenvironment. Scanning electron microscopy and Fourier-transform infrared spectroscopy revealed that LTP modulated the microstructures and chemical bindings of the SF gel. Improved cell viability, morphology, and extracellular matrix depositions by the LTP-treated SF hydrogel were identified with wound-healing assays and immunofluorescence staining. An irradiated random-pattern skin-flap animal model was established in six-week-old C57/BL6 mice. Full-thickness skin was flapped from the dorsum and SF hydrogel was placed underneath the raised skin flap. Postoperative histological analysis of the irradiated random-pattern skin-flap mice model suggested that LTP-treated SF hydrogel much improved wound regeneration and the inflammatory response compared to the SF hydrogel- and sham-treated groups. These results support that LTP-treated SF hydrogel significantly enhanced irradiated wound healing. Cellular and tissue reactions to released LTP from the SF hydrogel were favorable for the regenerative process of the wound; furthermore, mechanochemical properties of the SF gel were improved by LTP.

Abstract
BACKGROUND/AIM Using nationwide data from South Korea, we analyzed the prevalence of mental disorders among patients with nasopharyngeal carcinoma (NPC) who received radiotherapy (RT). PATIENTS AND METHODS Data were collected between January 2010 and December 2014, and 1,819 patients diagnosed with NPC who underwent RT were identified. We calculated the prevalence of the five most commonly diagnosed mental disorders and their incidences according to a time sequence based on the time of RT. RESULTS Among 1,819 patients, 144 (7.9%) were diagnosed at least once with a mental disorder between one year before the start of RT and the last follow-up. Based on the first diagnosis, 51 (35.4%) patients experienced anxiety, and 46 (31.9%) suffered from depression. The frequency of mental disorders increased up to the beginning of RT and then declined. Before the start of RT, anxiety was most frequent, and depression occurred after the start of RT. The cumulative incidence of mental disorders in the older age group tended to be higher than that of the younger group (≥54 vs. <54 years, log-rank p=0.052). CONCLUSION The proportion of mental disorders differed before and after the start of RT in patients with NPC. At the beginning of RT, mental disorders emerged most often during management. Early screenings and interventions for mental disorders were able to improve quality of life (QOL).

Abstract
BACKGROUND/AIM We quantified the incidence, and identified risk factors for influenza infection among childhood cancer survivors in South Korea, an at-risk population. PATIENTS AND METHODS Nationwide health insurance claims data were used to assess the frequency of influenza among childhood cancer survivors (aged <20 years) diagnosed between January 2009 and April 2016. A multivariable logistic regression was constructed to identify risk factors for influenza. RESULTS Of 6,457 children cancer survivors, 1,704 (27.0%) were diagnosed with influenza. Influenza was common in children <5 years old and infections were highest between late October and April. Over 60% of influenza treatment claims came from private clinics. Risk factors for influenza included age <9 years. CONCLUSION Childhood cancer survivors are particularly at-risk for influenza infection during the traditional influenza season. Identifying risks for influenza infection will help to establish countermeasures for reducing the influenza infections in at-risk cancer surviving children.

Abstract
Purpose This study describes the protocol for the design and evaluation of a self-assessment based educational program supporting cancer patients’ return-to-work (RTW), prior to its complete and ongoing implementation. Methods We designed a multi-center, randomized controlled trial with three follow-up points. The study population (N = 239) includes recently diagnosed cancer patients who plan to receive active treatment at two university hospitals in Korea. A pre-test is conducted at the point of enrollment for both groups. The intervention group receives a leaflet clarifying misconceptions about RTW and is shown a video clip of patient interviews concerning RTW. The control group receives a booklet about cancer and nutrition, and is not provided with further intervention. After active treatment, the intervention group receives a one-time, face-to-face education session with an oncology nurse. Following the education session, both groups receive three follow-up phone calls. The first follow-up call occurs at the end of intervention and at the end of active treatment for intervention and control groups, respectively. The next two follow-up calls will be conducted one month and a year following the post-test. The primary outcome is whether the patient has RTW or has plans to RTW, and the secondary outcome is knowledge of RTW. Results As of April 2020, 239 patients have been enrolled in the trial. Statistical analyses will be conducted upon trial completion in December 2020. Discussion We hypothesize that the provision of RTW education near diagnosis will not only enhance patients’ intentions to RTW, but also effectively encourage them to RTW.

Abstract
Excessive body fat and the related dysmetabolic diseases affect both developed and developing countries. The aim of this study was to investigate the beneficial role of a bacterial culture supernatant (hereafter: BS) of Lactobacillus and Bifidobacterium and their potential mechanisms of action on white-fat browning and lipolysis. For selection of four candidates among 55 Lactic acid producing bacteria (LAB) from human infant faeces, we evaluated by Oil Red O staining and Ucp1 mRNA quantitation in 3T3-L1 preadipocytes. The expression of browning and lipolysis markers was examined along with in vitro assays. The possible mechanism was revealed by molecular and biological experiments including inhibitor and small interfering RNA (siRNA) assays. In a mouse model, physiological, histological, and biochemical parameters and expression of some thermogenesis-related genes were compared among six experimental groups fed a high-fat diet and one normal-diet control group. The results allow us to speculate that BS treatment promotes browning and lipolysis both in vitro and in vivo. Moreover, the BS may activate thermogenic programs via a mechanism involving PKA-CREB signaling in 3T3-L1 cells. According to our data, we can propose that two LAB strains, Bifidobacterium longum DS0956 and Lactobacillus rhamnosus DS0508, may be good candidates for a dietary supplement against obesity and metabolic diseases; however, further research is required for the development as dietary supplements or drugs.

Abstract
Research Objective Global surgery is becoming an increasingly important global health agenda. Cardiovascular disease is the major cause of mortality around the world, and congenital heart disease is the leading cause of morbidity in children. This study aimed to investigate and illustrate the caregivers’ experiences of accessing the health care system and undergoing pediatric cardiac surgery for children with congenital heart disease (CHD). Study Design A qualitative study was conducted. Interviews were conducted in December 2019 in Amharic, then translated into English using trained local interpreters. Data were transcribed verbatim and analyzed according to the principles of interpretive thematic analysis, informed by the candidacy framework, using NVivo. The candidacy framework explores the access to health care utilization by seven elements: candidacy, navigation, the permeability of services, appearances at health services, adjudications, offers and resistance, and operating conditions and the local production of candidacy. Population Studied Interviews were conducted with 13 caregivers of 10 patients with congenital heart disease that received cardiac surgery during the week of the interview. Principal Findings The following three themes emerged from the interviews: (a) Recognition of CHD mostly took place at birth, but for those born at home, they found out much later (max 14 years); (b) CHD was misdiagnosed multiple times prior to seeking care at a large hospital; and (c) patients were waiting for the surgery for more than a year, (d) being scheduled for surgery induced both anxiety and hopefulness. In the discussion, caregivers had financial difficulties and struggled in a fragmented delivery system and experienced poor service quality such as the inaccuracy of diagnosis while navigating the Ethiopian health care system. Conclusions Major care‐seeking delays were related to the inefficient and complex health care system, largely due to lack of early CHD recognition and financial hardships. Financial protection is low despite the availability of fee waivers for medications. Low education attainment and distance to hospitals are contributing to this challenge. Implications for Policy or Practice Overall, Ethiopia needs to prioritize policies that protect the financial status of low‐income households that need health care services. Along with increasing health care workforce capacity for pediatric cardiac surgeries in Ethiopia, there is a need to strengthen the district‐level screening capacity to facilitate earlier diagnosis at easily accessible health care settings.

Abstract
Background This longitudinal study aimed to analyze the prevalence of psychological distress in esophageal cancer survivors, using claims data in South Korea. Methods From January 2010 to December 2014, we identified the four most frequent psychological distress in a nationwide cohort of 8,879 patients diagnosed with esophageal cancer. We analyzed the prevalence and the pattern of psychological distress before and after the initial treatment. Results Among esophageal cancer patients, 669 patients (7.5%) were diagnosed with a psychological distress between 1 year prior to initial treatment and the time of last follow-up. Among them, depression and anxiety had a similar frequency of 237 (35.4%). The overall frequency of psychological distress peaked within 2 months after the initial treatment. Stress reaction/adjustment disorders showed the highest increase rate after treatment. The rate of patients who had psychological distress was higher among those who underwent surgery as their initial treatment than in those who received radiotherapy [odds ratio (OR): 1.39, P<0.001]. Further, female patients were more likely to be diagnosed with psychological distress compared with male patients (OR: 1.30, P<0.001). Conclusions Psychological distress in esophageal cancer survivors showed different patterns of prevalence depending on the nature of disease, sex, and initial treatment. Considering individual factors, timely diagnosis and intervention for psychological distress could improve the quality of life for esophageal cancer survivors.

Abstract
BACKGROUND/AIMS We investigated metabolic comorbidity status and patterns of medical institution utilization among breast cancer survivors using medical claims data from the Health Insurance Review and Assessment Service (HIRA). METHODS Using claims data obtained from the HIRA, we selected breast cancer survivors between 2010 and 2015. Descriptive statistics were calculated to determine the frequency of metabolic comorbidities, as well as to analyze patterns of medical institution utilization in accordance with disease status. RESULTS A total of 89,953 breast cancer survivors were identified. Among these, 12,364 (13.7%) had hypercholesterolemia, 20,754 (23.1%) had hypertension (HTN), and 11,102 (12.3%) had diabetes mellitus (DM). In particular, more than half of breast cancer survivors older than 60 years had HTN, and other diseases sharply increased beginning at age 50 years. For HTN, a total of 531,292 claims were submitted; more than 80% (n = 473,737) were from primary medical institutions, whereas only 2.4% (n = 12,551) were from tertiary medical institutions. The number of claims submitted for DM was 231,526; those from primary medical institutions accounted for 68.5% (n = 158,566), whereas claims from tertiary medical institutions accounted for 12.0% (n = 27,693). In subgroup analyses, the utilization of secondary and tertiary medical institutions was higher among patients with severe diseases and those diagnosed following their breast cancer diagnosis. CONCLUSION More than 10% of breast cancer survivors were diagnosed with a metabolic comorbidity. Through analysis of medical institution utilization patterns, we ascertained that a communication system linking secondary and tertiary medical institutions with primary medical institutions is needed.

Abstract
The synthesis of a palladium-containing iodovanadinite derivative, hypothetically “PdPb9(VO4)6I2”, was attempted using PdI2 as a source of iodine in searching for a novel waste form for radioiodine. Stoichiometric amounts of Pb3(VO4)2 and PdI2 were batched and reacted at elevated temperatures in sealed vessels. Batched material was also subjected to high-energy ball-milling (HEBM) in order to reduce reaction time and the potential for iodine volatilization during subsequent reaction at 200–500 °C. The resulting products were characterized using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray analysis, IR spectroscopy, thermal analysis and Pd K XANES. Results showed that PdI2 can function as a sacrificial iodine source for the formation of iodovanadinite, prototypically Pb10(VO4)6I2, however, the incorporation of Pd into this phase was not definitively observed. The sacrificial reaction mechanism involved the decomposition of PdI2 to Pd metal and nascent I2, with the latter incorporated into the iodovanadinite Pb10(VO4)6I2 phase. In comparison to processing using standard solid state reaction techniques, the use of HEBM prior to high temperature reaction generates a more homogeneous end-product with better iodine retention for this system. Overall, the key novelty and importance of this work is in demonstrating a method for direct immobilisation of undissolved PdI2 from nuclear fuel reprocessing, in a composite wasteform in which I-129 is immobilised within a durable iodovandinite ceramic, encapsulating Pd metal. The synthesis and characterisation of a composite wasteform, comprising iodovanadinite Pb10(VO4)6I2 and Pd metal, is reported, for immobilisation of radioiodine PdI2; the formation of Pd incorporated iodovanadinite “PdPb9(VO4)6I2” was not observed.![]()

Abstract
BACKGROUND/AIM This longitudinal study aimed to analyze the prevalence of endocrine disorders in childhood brain tumor survivors in South Korea using claims data. PATIENTS AND METHODS We identified in 1,058 patients from a nationwide cohort of patients diagnosed with brain tumors between January 1st 2009 to March 29th 2016. Multivariable logistic regression was used to evaluate associations between clinical factors and endocrine disorders. RESULTS After a median follow-up of 60.0 months, 393 (37.1%) patients had at least 1 endocrine disorder. The commonest endocrine disorders were hypopituitarism (17.4%) and hypothyroidism (6.1%). Female gender (odds ratio(OR)=1.45, p=0.005) and age <10 years (OR=1.65, p=0.001) conferred a higher risk. Patients who received radiotherapy were more likely to have endocrine disorders compared to those who did not (OR=1.79, p<0.001). CONCLUSION Regular assessment of endocrine function and timely interventions are necessary for childhood brain tumor survivors with a risk of endocrine disorders.

Abstract
Pexastimogene devacirepvec (Pexa-Vec) is a vaccinia virus-based oncolytic immunotherapy designed to preferentially replicate in and destroy tumor cells while stimulating anti-tumor immunity by expressing GM-CSF. An earlier randomized Phase IIa trial in predominantly sorafenib-naïve hepatocellular carcinoma (HCC) demonstrated an overall survival (OS) benefit. This randomized, open-label Phase IIb trial investigated whether Pexa-Vec plus Best Supportive Care (BSC) improved OS over BSC alone in HCC patients who failed sorafenib therapy (TRAVERSE). 129 patients were randomly assigned 2:1 to Pexa-Vec plus BSC vs. BSC alone. Pexa-Vec was given as a single intravenous (IV) infusion followed by up to 5 IT injections. The primary endpoint was OS. Secondary endpoints included overall response rate (RR), time to progression (TTP) and safety. A high drop-out rate in the control arm (63%) confounded assessment of response-based endpoints. Median OS (ITT) for Pexa-Vec plus BSC vs. BSC alone was 4.2 and 4.4 months, respectively (HR, 1.19, 95% CI: 0.78–1.80; p = .428). There was no difference between the two treatment arms in RR or TTP. Pexa-Vec was generally well-tolerated. The most frequent Grade 3 included pyrexia (8%) and hypotension (8%). Induction of immune responses to vaccinia antigens and HCC associated antigens were observed. Despite a tolerable safety profile and induction of T cell responses, Pexa-Vec did not improve OS as second-line therapy after sorafenib failure. The true potential of oncolytic viruses may lie in the treatment of patients with earlier disease stages which should be addressed in future studies. ClinicalTrials.gov: NCT01387555

Abstract
e21517 Background: Brain tumors are the most common solid cancers in child patients with a current expected 5-year overall survival rate of 73%. Also, patients with brain cancer tend to have a high rate of neuroendocrine disorders. These endocrine problems may have a significant negative effect on quality of life and treatment compliance. Methods: The aim of this longitudinal study was to analyze the prevalence of endocrine disorders in childhood brain tumor survivors using claims data in South Korea. We confirmed endocrine disorders in a nationwide cohort of 1,058 patients who were diagnosed with brain tumor between January 1, 2009 and March 29, 2016 and who survived > 2 years after diagnosis. Multivariable logistic regression was used to evaluate association between demographic and treatment related variables and the prevalence of endocrine disorders. Results: After a median follow-up of 60.0 months, a total of 393 (37.1%) patients were diagnosed with at least one endocrine disorder. The median follow-up time from primary brain tumor diagnosis to diagnosis of first endocrine disorders was 26.3 months (range, 0.06 to 96.7). Of those patients, 333 childhood brain tumor survivors were diagnosed with endocrine disorders during their first 5 years after diagnosis. The overall frequency of endocrine disorders peaked during 2 months after the cancer diagnosis. The most common endocrine disorders were pituitary dysfunction (21.9%), thyroidal disease (6.1%), precocious puberty (4.6%), and growth hormone deficiency (4.3%). Female patients were at a higher risk for endocrine disorders (odds ratio: 1.45, p = 0.005). The patients with radiotherapy were more likely to have endocrine disorders compared without radiotherapy (odds ratio: 1.79, p < 0.001). Conclusions: Endocrine disorders in childhood brain tumor survivors was high and showed different patterns of prevalence depending on the nature of disease and time sequence. In childhood brain tumor survivors who are risk of endocrine disorders, regular assessment of endocrine function and timely intervention were needed. [Table: see text]

Abstract
AIM This time-dependent study aimed to analyze the prevalence of psychological distress in prostate cancer survivors by using claims data in South Korea. METHODS In a nationwide cohort, 32 005 patients were identified who were diagnosed with prostate cancer between January 2010 and December 2014. We referred the diagnostic codes of mental disorders as psychological distress. We categorized the prevalence of psychological distress based on age and specific times before and after the cancer diagnosis. RESULTS The median age at diagnosis of prostate cancer was 70 years. Among 32 005 patients, 3074 (9.6%) were diagnosed at least once with a mental disorder between 1 year before the cancer diagnosis and the last follow-up. Among the first diagnoses of each patient, the common mental disorders were anxiety (39.1%) and depression (33.0%). In the total cohort, there were 54 666 claims for mental disorders and over 48.0% (26 256) were for depression. The frequency of psychological distress peaked just before cancer diagnosis. Anxiety was frequent before diagnosis of prostate cancer, whereas depression was frequent after diagnosis. Although stress reaction/adjustment disorders were relatively high in the younger group, depression was relatively high in the elderly group. CONCLUSION Psychological distress in prostate cancer survivors showed different patterns of prevalence between before and after cancer diagnosis, as well as between age groups. Timely diagnosis and intervention for mental health could promote quality of life for prostate cancer survivors.

Abstract
Salvage therapy for recurrent high grade gliomas (HGG) includes surgery, radiotherapy and chemotherapy, however, standard treatment does not exist. We evaluated the tolerability and efficacy of re-irradiation (re-RT) with hyperthermia (HT) for patients with recurrent HGG. From September 2010 to July 2015, 20 patients with recurrent HGG were treated with re-RT and HT. The radiotherapy dose of 30 Gray (Gy) was delivered with 2 Gy per fraction daily, and HT was performed twice weekly. Primary endpoints were treatment compliance and toxicity. Second endpoints were overall survival (OS) and progression free survival (PFS). The median interval between initial RT and re-RT was 11 months. During re-RT with HT, there were no significant acute morbidities over grade 3. Median overall survival (OS) from re-irradiation was 8.4 months and the 6 and 12 months survival rate were 67% and 30%, respectively. The median progression free survival (PFS) from re-irradiation was 4.1 month. Our findings suggested that concurrent re-RT with HT was a safe and well-tolerated. In addition, the combination re-RT and HT could be a valuable salvage treatment option for selected recurrent HGG patients with poor performance status.

Abstract
We analyzed the changes in absolute lymphocyte count and its changes over time in 139 patients treated with preoperative chemoradiotherapy for locally advanced rectal cancer. The baseline absolute lymphocyte count was defined as the median of absolute lymphocyte count levels measured during 30 days before preoperative chemoradiotherapy. Absolute lymphocyte count at 1 month, 0.5 to 1 year, 1 to 2 years, and 2 to 3 years were determined by the median values of the absolute lymphocyte counts during the respective periods. Absolute lymphocyte count decreased after delivering preoperative chemoradiotherapy, reached minimum level at 1 month, and then gradually increased after the completion of chemoradiotherapy. Baseline absolute lymphocyte count had significant correlations with the absolute lymphocyte count of every period (range of coefficient, 0.41-0.64, P < .001). The overall survival of the group with high baseline absolute lymphocyte count was significantly higher than that of the group with low baseline absolute lymphocyte count (5-year overall survival: 82.4% vs 62.9%, P = .012). In multivariable analyses, the baseline absolute lymphocyte count remained as a significant prognostic factor for overall survival, favoring the group with a high baseline absolute lymphocyte count (hazard ratio = 0.405, P = .017). This study showed that the level of baseline absolute lymphocyte count was an independent prognostic factor, and it correlated with the absolute lymphocyte counts across varying periods of treatments and follow-up in patients treated with preoperative chemoradiotherapy for rectal adenocarcinoma.

Abstract
OBJECTIVE This longitudinal study aimed to analyze the prevalence of mental disorders in endometrial cancer survivors in South Korea. METHODS We assessed mental disorders in a nationwide cohort of 8,155 patients who were diagnosed with endometrial cancer between January 1, 2010, and December 31, 2014. We categorized the prevalence of mental disorders based on age and time of diagnosis. RESULTS Based on the first diagnosis, mental disorders were identified in 567 (7.0%) among patients with endometrial cancer. Of those patients, 249 (43.9%) were diagnosed with depression and 248 (43.7%) with anxiety. The overall incidence of mental disorders peaked within 2 months after hysterectomy. The rate of stress reaction/adjustment disorder increased most rapidly among the mental disorders after hysterectomy. While depression rates were relatively high among younger individuals (under 50 years), anxiety was more frequent in older people (over 50 years old). In the entire prescription (n=6,034), depression had the highest incidence (n=3,801), followed by anxiety (n=1,774). Over 89% (n=5,362) of the mental disorder treatment claims were from psychiatric medical departments. CONCLUSION Mental disorders showed different prevalence patterns among endometrial cancer survivors depending on patient age and the nature of the disease. Intensive and personalized management of distress is necessary for endometrial cancer survivors.

Abstract
Background This study aimed to evaluate patterns of posttransplant malignancies among renal transplant recipients (RTRs) in South Korea using nationwide data. Methods The nationwide cohort assessed in this study included RTRs from January 1, 2010, to December 31, 2014. We analyzed cancer incidence during the time course after renal transplantation. Additionally, we calculated standardized incidence ratios (SIRs) to evaluate the risk of malignancies in RTRs. Results A total of 1343 RTRs (871 males and 472 females, mean age 48.5 ± 11.6 years) were assessed. Among them, 104 (7.7%) developed malignancies after transplantation, most commonly in the thyroid cancer (23.1%). The SIR for all cancers was 3.54; particularly, the SIRs for renal cancer, myeloma, and non-Hodgkin lymphoma were 16.31, 24.02, and 28.64, respectively. Females showed a higher risk of malignancy than males (SIRs: 4.04 for women and 3.26 for men). The median interval between transplantation and malignancy diagnosis was 27.2 months (range 12.3–54.8 months). Conclusions RTRs in South Korea demonstrated a high risk of malignancy after transplantation compared with the general population. This indicates that close surveillance and routine screening for cancer in RTRs are needed.

Abstract
The main purpose of this study was to evaluate the effectiveness of the education system using social media. Eight educational video clips were developed instructing the viewer on cancer-related issues such as prevention, treatment, and survivorship. Each video was made with participation of medical professors and posted on a YouTube channel. A mobile phone application was produced containing a scheduler function, introduction of a community cancer center program, and cancer information. A medical blog was established to provide stationary materials such as images and articles. Descriptive analysis was done by Google analytics. From May of 2014 to June of 2016, 15,247 total views were recorded on the YouTube channel, and the average view duration was about 3 min. The most popular video was about chemotherapy treatment; 5409 (36%) people watched this video, and 3615 (23.5%) people viewed a video on balanced dietary habits. As well as South Korea, 1,113 (7%) views were confirmed in the United States and 175 (1%) in Japan. The equipment used to watch the contents were mobile phones (59%), laptops (33%), and tablets (6%). Five hundred people installed the smartphone application from March of 2015 to July of 2016. Three hundred eighty-three medical contents were posted on the blog since March of 2015. Cancer education is necessary to address the education needs of patients with cancer and their caregivers. Education based on social media could be an effective method that reaches beyond geographical boundaries.

Abstract
The use of analgesics and sedatives plays an important role in improving patient outcomes in the intensive care unit (ICU). Various drugs exist, each with associated differences in patient outcomes; therefore, critical and intensive care medicine societies have developed guidelines for usage of analgesics and sedatives for improved patient outcomes. However, studies investigating drug use in the ICU have been based on surveys administered to medical staff, without accurate insight into the drug use based on prescriptions and behaviors of ICU medical staff, thus failing to demonstrate the actual status of the implementation of these guidelines into clinical practice. Using data from the Health Insurance Review and Assessment Service in South Korea, we analyzed the current use of analgesics and sedatives in ICUs nationally. In addition, we compared the use of analgesics and sedatives in the ICU based on the latest guidelines.We performed a nationwide retrospective study using data available in the Health Insurance Review and Assessment Service database. We included 779,985 patients who had been admitted to the ICU from January 1, 2010, to December 31, 2014. Descriptive statistics were calculated to analyze the type and frequency of analgesic and sedative use in the ICU, using drug codes for analgesics and sedatives commonly prescribed in the ICU.The most commonly used analgesics and sedatives for all patients admitted to the ICU were pethidine (26.14%) and midazolam (32.18%), respectively. Sedatives and analgesics were more commonly used in mechanically ventilated patients. Among analgesics, the usage rate of pethidine and morphine decreased, whereas the usage rate of fentanyl and remifentanil increased. Among sedatives, the usage rate of benzodiazepine decreased, whereas the usage rate of propofol increased.There was discordance between current usage of analgesics and sedatives and the recommended usage stipulated by ICU guidelines. However, the trend of drug usage is changing to match the guidelines, which recommend maintenance of light sedation using an analgesia-based regimen and usage of short-acting drugs for routine monitoring of pain, agitation, and delirium in ICU care.

Abstract
BACKGROUND/AIM In this study, we analyzed the prevalence of influenza disease in breast cancer survivors using claims data from the Health Insurance Review and Assessment Service (HIRA) in South Korea. PATIENTS AND METHODS We defined influenza among a nationwide cohort of 87,843 patients who were diagnosed with breast cancer and underwent surgery from January 1, 2010 to December 31, 2014, based on HIRA claim data. Descriptive statistics were calculated to estimate the frequency of influenza disease using diagnostic code and utilization pattern at medical institutions. RESULTS Two thousand four hundred breast cancer survivors (2.7%) were diagnosed with influenza. The overall frequency of influenza increased from November (n=98) and peaked in February (n=1,745). Over 60% (2,693) of claims for influenza disease treatment were in the clinic, whereas general hospitals accounted for 22.0% (873). Among 3,967 claims, admission rate was 7.6% (n=301) and the average length of hospitalization was 4.7 days. Elderly breast cancer survivors over 70 years old had the longest length of hospitalization at 5.9 days. CONCLUSION Breast cancer survivors are more susceptible to influenza than non-cancer survivors. It is important not only to raise the vaccination rate among young cancer survivors, but also to quickly identify symptoms and begin treatment for flu in elderly cancer survivors.

Abstract
PURPOSE Postoperative radiation therapy may have a detrimental effect on survival in patients with non-small cell lung cancer. We investigated the association of the lung radiation dose with the risk of death in patients treated with postoperative radiation therapy. METHODS We analyzed 178 patients with non-small cell lung cancer who received postoperative radiation therapy. The mean lung dose was calculated from dose-volume data, and we categorized patients into the high and low lung dose groups using 2 different methods; (1) simple grouping using the median lung dose of all patients, and (2) stratified grouping using the median lung dose of each subgroup sharing the same confounders. We compared clinical variables, and survival between the high and low lung dose groups. RESULTS In the simple grouping, there were no significant differences in survivals between the high and low lung dose groups. After stratification, the overall survival of low lung dose group was significantly longer than that of high lung dose group (5-year survival, 60.1% vs. 35.3%, p = 0.039). On multivariable analyses, the lung dose remained a significant prognostic factor for overall survival (hazard ratio, HR = 2.08, p = 0.019). CONCLUSIONS The lung dose was associated with the risk of death in patients with non-small cell lung cancer having the same confounders. Further studies evaluating the risk of death according to the lung dose will be helpful to administer more precise and individualized postoperative radiation therapy.

Abstract
OBJECTIVES The aim of this study was to analyze the prevalence of mental disorders in patients undergoing liver transplantation (LT) based on claims data from the Health Insurance Review and Assessment Service (HIRA) in South Korea. METHODS We confirmed mental disorders in a nationwide cohort of 3758 patients receiving LT between January 2010 and December 2014. We categorized the prevalence of mental disorders based on patient age at the time of LT. RESULTS A total of 288 patients for LT were diagnosed with a mental disorder 1 year before their cancer diagnosis. Of those patients, depression was present in 90 (31.25%) and anxiety in 92 (31.9%) patients at the first diagnosis. The overall frequency of mental disorders peaked just before LT, and substance abuse was the most prevalent mental disorder before LT. The risk of mental disorders after LT was significantly lower in those with hepatocellular carcinoma (HCC) than in those without HCC (hazard ratio = 1.70, p < 0.001). CONCLUSIONS Mental disorders in patients receiving LT showed different patterns of prevalence depending on age at the time of surgery and the nature of underlying diseases. Personalized intervention based on patient characteristics could improve the quality of life.
