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 NSCLC who underwent contrast-enhanced CT scans EGFR mutation testing before treatment were selected for the final study. Regions interest segmented from images extract features obtain tumor images. These input into convolutional neural network model 512...
In this study, we developed a deep learning model to identify patients with tongue cancer based on validated dataset comprising oral endoscopic images. We retrospectively constructed of 12,400 verified images from five university hospitals in South Korea, collected between 2010 and 2020 the participation otolaryngologists. To calculate probability malignancy using various convolutional neural network (CNN) architectures, several models were developed. Of total images, 5576 related extracted....
Objectives The aims of this study were to develop a smartphone application encourage breast self-examination (BSE), and evaluate the effects in terms modifying BSE behavior. Methods A application, based on Android OS, was developed with functions including date alarm, reminder mother daughter practice together, record keeping, educational content video clips. Females aged 19 over enrolled effectiveness application. Two series questionnaires carried out (before after use application) by...
Purpose The objective of this study was to explore the relationship between circulating lymphocyte level during preoperative chemoradiotherapy (CRT) and pathologic complete response (pCR) in locally advanced rectal cancer. Materials Methods From May 2010 2013, 52 patients treated with CRT followed by surgery, were analysed. Patients received conventional fractionated radiotherapy (50-54 Gy) fluorouracil-based chemotherapy. Surgical resection performed at 4 8 weeks after completion CRT....
Abstract Immune checkpoint inhibitors (ICI) have become the standard treatment for advanced non-small cell lung cancer (NSCLC). PD-L1 immunohistochemistry (IHC), only approved biomarker predicting ICI response, shows limited predictive value, particularly in patients with low expression (1-49%). Abnormal tumor vasculature NSCLC correlates poor prognosis and hampers efficacy by obstructing drug delivery suppressing immune activation. We developed an AI-based that predicts immunotherapy...
In this paper, we propose a quantum-secured single-pixel imaging method that utilizes non-classical correlations of photon pair. Our can detect any attempts to deceive it by exploiting correlation pairs while rejecting strong chaotic light illumination through heralding. A security analysis based on polarization-correlation has been conducted, demonstrating our improved compared existing imaging. More specifically, partial deceiving attack, which sends mixture true and false signal, be...
We analyzed the changes in absolute lymphocyte count and its over time 139 patients treated with preoperative chemoradiotherapy for locally advanced rectal cancer. The baseline was defined as median of levels measured during 30 days before chemoradiotherapy. Absolute at 1 month, 0.5 to year, 2 years, 3 years were determined by values counts respective periods. decreased after delivering chemoradiotherapy, reached minimum level then gradually increased completion Baseline had significant...
A proportion of patients with chronic obstructive pulmonary disease (COPD) may progress rapidly to small cell lung cancer (SCLC). As the forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) ratio is usually impaired COPD, and given that FEV1 FVC are not necessarily related development, we performed this study test our hypothesis FEV1/FVC predicts survival limited-stage (LS)-SCLC.We assessed 74 LS-SCLC treated chemoradiotherapy. The were divided into two groups: <0.74...
This study aimed to evaluate patterns of posttransplant malignancies among renal transplant recipients (RTRs) in South Korea using nationwide data. The cohort assessed this included RTRs from January 1, 2010, December 31, 2014. We analyzed cancer incidence during the time course after transplantation. Additionally, we calculated standardized ratios (SIRs) risk RTRs. A total 1343 (871 males and 472 females, mean age 48.5 ± 11.6 years) were assessed. Among them, 104 (7.7%) developed...
The aim of this time-dependent study was to analyze the prevalence mental disorders in ovarian cancer survivors using claims data South Korea.We confirmed a nationwide cohort 9763 patients who were diagnosed with between January 1, 2010 and December 31, 2014. We categorized based on age time diagnosis.A total 821 disorder, 1 year prior diagnosis. Of those patients, 311 depression (37.9%) 245 anxiety (29.8%) during their first visit. overall frequency peaked within 2 months after highest rate...
Purpose Parotid gland can be considered as a risk organ in whole brain radiotherapy (WBRT). The purpose of this study is to evaluate the parotid sparing effect computed tomography (CT)-based WBRT compared 2-dimensional plan with conventional field margin. Materials and Methods From January 2008 April 2011, 53 patients underwent using CT-based simulation. Bilateral two-field arrangement was used prescribed dose 30 Gy 10 fractions. We between 2 plans different lower margins: level atlas (CF)...
The purpose of this study was to investigate the prognostic effect pulmonary function at beginning postoperative radiotherapy (PORT) in non-small cell lung cancer (NSCLC).From January 2002 December 2012, 115 patients with NSCLC who underwent PORT and took forced expiratory volume 1 second (FEV1) were analysed. began within 4-6weeks following surgery, 3-dimensional conformal technique used conventional fractionation. high low FEV1 groups divided by median absolute value PORT, we compared...
Distributed Denial-of-Service attack (DDoS) is one of the most outstanding menaces on Internet. A DDoS generally attempts to overwhelm victim in order deny their services legitimate users. number approaches have been proposed for defending against attacks accurately real time. However, existing schemes limits terms detection accuracy and delay if IDRS (Intrusion Detection Response System) deployed only at a specific location detects responds attacks. As this case, it not able catch...
In this study, we analyzed the prevalence of influenza disease in breast cancer survivors using claims data from Health Insurance Review and Assessment Service (HIRA) South Korea.We defined among a nationwide cohort 87,843 patients who were diagnosed with underwent surgery January 1, 2010 to December 31, 2014, based on HIRA claim data. Descriptive statistics calculated estimate frequency diagnostic code utilization pattern at medical institutions.Two thousand four hundred (2.7%) influenza....
Background/Aims We investigated metabolic comorbidity status and patterns of medical institution utilization among breast cancer survivors using claims data from the Health Insurance Review Assessment Service (HIRA). Methods Using obtained HIRA, we selected between 2010 2015. Descriptive statistics were calculated to determine frequency comorbidities, as well analyze in accordance with disease status. Results A total 89,953 identified. Among these, 12,364 (13.7%) had hypercholesterolemia,...
This longitudinal study aimed to analyze the prevalence of psychological distress in esophageal cancer survivors, using claims data South Korea.From January 2010 December 2014, we identified four most frequent a nationwide cohort 8,879 patients diagnosed with cancer. We analyzed and pattern before after initial treatment.Among patients, 669 (7.5%) were between 1 year prior treatment time last follow-up.
