Abstract
研究目的:本研究使用羅吉斯迴歸、支持向量機、決策樹、隨機森林、梯度提升及人工神經網路等機器學習演算法,預測可能造成肝癌復發的危險因子,減少肝癌病人復發的機會。
研究方法:以回溯性世代研究方法,收集2000年至2021年臺北醫學大學臨床研究資料庫中1,201位肝癌病人的相關資料,利用六種機器學習方法將所蒐集之樣本進行隨機分組,建立預測模型,納入人口學變項、生活習慣、過去病史、疾病狀況及治療方式等資料,以準確率、敏感度、特異度、陽性預測值、F1-score及AUC等指標,選擇最準確的演算法,預測可能導致肝癌復發的危險因子。
研究結果:研究結果顯示,1,201位肝癌病人中共有562人發生肝癌復發,復發率為46.79%。在機器學習模型預測肝癌復發危險因子方面,外部驗證以人工神經網路之模型預測結果最佳,其準確率為0.7399、敏感度為0.7857、特異度為0.6905、陽性預測值為0.6688、AUC為0.7399,再根據此模型分析肝癌復發變項重要程度,以喝酒習慣為造成肝癌復發最重要的危險因子,其次為血型,淋巴管或血管侵犯則為危險因子第三名。建議醫療提供者可將本研究機器學習模型的預測結果作為參考,相信有助於提升病人預後效果,為醫病雙方帶來最大的價值,減少肝癌病人復發的機會。
