An Integrated Approach For Uncovering Novel DNA Methylation Biomarkers For Non-small Cell Lung Carcinoma

為了解決CT scan的問題，作者VAIBHAV KUMAR SUNKARIA 這樣論述：

Introduction - Lung cancer is one of primal and ubiquitous cause of cancer related fatalities in the world. Leading cause of these fatalities is non-small cell lung cancer (NSCLC) with a proportion of 85%. The major subtypes of NSCLC are Lung Adenocarcinoma (LUAD) and Lung Small Cell Carcinoma (LUS

C). Early-stage surgical detection and removal of tumor offers a favorable prognosis and better survival rates. However, a major portion of 75% subjects have stage III/IV at the time of diagnosis and despite advanced major developments in oncology survival rates remain poor. Carcinogens produce wide

spread DNA methylation changes within cells. These changes are characterized by globally hyper or hypo methylated regions around CpG islands, many of these changes occur early in tumorigenesis and are highly prevalent across a tumor type.Structure - This research work took advantage of publicly avai

lable methylation profiling resources and relevant comorbidities for lung cancer patients extracted from meta-analysis of scientific review and journal available at PubMed and CNKI search which were combined systematically to explore effective DNA methylation markers for NSCLC. We also tried to iden

tify common CpG loci between Caucasian, Black and Asian racial groups for identifying ubiquitous candidate genes thoroughly. Statistical analysis and GO ontology were also conducted to explore associated novel biomarkers. These novel findings could facilitate design of accurate diagnostic panel for

practical clinical relevance.Methodology - DNA methylation profiles were extracted from TCGA for 418 LUAD and 370 LUSC tissue samples from patients compared with 32 and 42 non-malignant ones respectively. Standard pipeline was conducted to discover significant differentially methylated sites as prim

ary biomarkers. Secondary biomarkers were extracted by incorporating genes associated with comorbidities from meta-analysis of research articles. Concordant candidates were utilized for NSCLC relevant biomarker candidates. Gene ontology annotations were used to calculate gene-pair distance matrix fo

r all candidate biomarkers. Clustering algorithms were utilized to categorize candidate genes into different functional groups using the gene distance matrix. There were 35 CpG loci identified by comparing TCGA training cohort with GEO testing cohort from these functional groups, and 4 gene-based pa

nel was devised after finding highly discriminatory diagnostic panel through combinatorial validation of each functional cluster.Results – To evaluate the gene panel for NSCLC, the methylation levels of SCT(Secritin), FOXD3(Forkhead Box D3), TRIM58(Tripartite Motif Containing 58) and TAC1(Tachikinin

1) were tested. Individually each gene showed significant methylation difference between LUAD and LUSC training cohort. Combined 4-gene panel AUC, sensitivity/specificity were evaluated with 0.9596, 90.43%/100% in LUAD; 0.949, 86.95%/98.21% in LUSC TCGA training cohort; 0.94, 85.92%/97.37 in GEO 66

836; 0.91,89.17%/100% in GEO 83842 smokers; 0.948, 91.67%/100% in GEO83842 non-smokers independent testing cohort. Our study validates SCT, FOXD3, TRIM58 and TAC1 based gene panel has great potential in early recognition of NSCLC undetermined lung nodules. The findings can yield universally accurate

and robust markers facilitating early diagnosis and rapid severity examination.

基於影像前處理的卷積神經網路偵測ST段上升型心肌梗塞疾病

為了解決CT scan的問題，作者林怡均 這樣論述：

心血管疾病一直都是國人十大死因的前幾名，其中急性冠心症(Acute Coronary Syndrome, ACS)最為致命。急性冠心症的臨床機轉為供應心臟的冠狀動脈血管產生狹窄、阻塞，使心肌無法獲得氧氣、營養，進而引起心臟壞死，其中又以ST段上升心肌梗塞(STEMI)疾病的心肌受損程度會隨著時間的增加而迅速擴大最為危急。在診斷方面，急性冠心症的主要診斷工具為心電圖，心電圖以非侵入式的方式監測、紀錄下心臟的生理活動並產生心電圖，醫生可根據心電圖去區分急性冠心症的類型，進而決定進行何種治療。現今台灣的救護車多配置生理監視器，在出勤時能針對疑似心臟疾病患者做初步的判斷，在救護途中將量測的心電圖回傳

遠端醫院的醫師進行判斷，這樣的作業模式須依賴心臟專科醫師隨時待命來完成，效率較為低落，若使用科技輔助，將能大幅減少時間成本，達到迅速判讀、準確救護的目的。近年來，由於深度學習方法迅速進展，特別是關於影像分類的CNN模型能夠出色的解決複雜的影像問題，因此被廣泛運用於醫學影像分類。然而一般訓練CNN模型需要大量的影像資料才能獲得準確的分類結果，然而一般醫院的STEMI患者的數量並不算多。本研究的目的在探討心電圖資料相對較少的前提下，分析不同的影像前處理方法對CNN為基礎的深度學習模型的表現，包含影像去背、形態學處理、影像增強等影像前處理技術優化心電圖影像，最後再透過不同的CNN模型，判斷ST段上升

型心肌梗塞患者。本研究中，我們僅使用602張圖片，分別在多個CNN模型中進行訓練、測試，包含EfficientNet、ResNet、DenseNet皆得到87%以上的準確率，證實影像前處理之重要性。
