Abstract
腎病症候群 ( Nephrotic Syndrome,NS ) 是由一群會造成腎臟功能異常的疾病總稱,最常見的病理症狀如蛋白質由尿中流失、血液白蛋白降低等。目前腎病症候群雖可透過理學檢查、尿液常規檢查、血液常規檢查來做診斷,但往往仍然無法釐清病因。導致腎病症候群的原因很多,不同的病理變化會對應不同的治療處置,尚須以侵入性之腎臟切片進行確認。倘若有更即時性且非侵入性的評估方式,對於臨床診斷及治療會具有更大的價值。

本實驗使用臺北醫學大學附設醫院、臺北市立萬芳醫院、衛生福利部雙和醫院及馬偕紀念醫院共四間醫院資料庫,2011年01月至2021年06月診斷為腎病症候群之病患,其抽血及驗尿報告搭配國際疾病與相關健康問題統計分類第十版( ICD-10 ),進行腎臟切片分型的預測。使用K-NN Imputer將遺失值補值,並將data區分為80% Training Set、20% Test Set。Training set使用SMOTE處理不平衡資料,並以5-fold Cross-Validation訓練Random Forest、XGBoost、Logistic Regression、SVM及K-NN等5種模型,最終以Accuracy及AUC作為評估方式。

在ICD-10編碼N04.0腎病症候群伴有輕微腎絲球異常族群中,Random Forest之Accuracy 83.0%、AUC 0.697;N04.1腎病症候群伴有局部及節段性腎絲球病灶,Random Forest之Accuracy 88.4%、AUC 0.886;N04.2腎病症候群伴有瀰漫性膜性腎絲球腎炎,在Random Forest之Accuracy分別為86.8%、AUC 0.833。整體而言,使用Random Forest不論在哪個分類族群中,均可獲得不錯的表現,對於醫師及病人均可提供另一個診斷協助。
