This requires understanding the treatment heterogeneity from a patient-centric view, quantified by estimating the individualized treatment effect (ITE). With a large amount of genetics data and medical factors being collected, a complete picture of individuals\u2019 characteristics is forming, which provides more opportunities to accurately estimate ITE. Recent development using machine learning methods within the counterfactual outcome framework shows excellent potential in analyzing such data. In this research, we propose to extend meta-learning approaches to estimate individualized treatment effects with survival outcomes. Two meta-learning algorithms are considered, T-learner and X-learner, each combined with three types of machine learning methods: random survival forest, Bayesian accelerated failure time model and survival neural network. We examine the performance of the proposed methods and provide practical guidelines for their application in randomized clinical trials (RCTs). Moreover, we propose to use the Boruta algorithm to identify risk factors that contribute to treatment heterogeneity based on ITE estimates. The finite sample performances of these methods are compared through extensive simulations under different randomization designs. The proposed approach is applied to a large RCT of eye disease, namely, age-related macular degeneration (AMD), to estimate the ITE on delaying time-to-AMD progression and to make individualized treatment recommendations.<\/jats:p>","DOI":"10.6339\/24-jds1119","type":"journal-article","created":{"date-parts":[[2024,2,5]],"date-time":"2024-02-05T07:17:16Z","timestamp":1707117436000},"page":"505-523","source":"Crossref","is-referenced-by-count":3,"title":["A Meta-Learner Framework to Estimate Individualized Treatment Effects for Survival Outcomes"],"prefix":"10.6339","author":[{"given":"Na","family":"Bo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Wei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lang","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaeryon","family":"Kang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1352-1000","authenticated-orcid":false,"given":"Ying","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"28744","published-online":{"date-parts":[[2024,2,5]]},"reference":[{"issue":"6","key":"2024102410355175278_j_jds1119_ref_001","doi-asserted-by":"publisher","first-page":"573","DOI":"10.1016\/S0197-2456(99)00031-8","article-title":"The age-related eye disease study (AREDS): design implications.
