Kishan","aka":[],"tldr":"Radiation oncologist who showed MRI-guided prostate radiotherapy causes fewer side effects.","summary":"Amar Kishan is Professor and Vice Chair of Clinical and Translational Research in Radiation Oncology at UCLA, part of the UCLA Jonsson Comprehensive Cancer Center. A radiation oncologist specialising in prostate radiotherapy, MR-guided radiotherapy and hypofractionation, he led MIRAGE, the randomised trial of MRI-guided versus CT-guided stereotactic body radiotherapy for prostate cancer, which showed fewer side effects with MRI guidance. His papers report the MIRAGE trial in JAMA Oncology and an individual patient data meta-analysis of androgen deprivation therapy use and duration with definitive radiotherapy for localised prostate cancer in Lancet Oncology. His record also links to the ArteraAI Prostate test.","asOf":"2026-09-08","links":[{"label":"UCLA profile","url":"https://www.uclahealth.org/providers?q=Amar%20U.%20Kishan"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Kishan%20AU%5BAuthor%5D"},{"label":"Google Scholar","url":"https://scholar.google.com/scholar?q=Amar%20U.%20Kishan"}],"tags":[],"related":[],"cancers":["prostate"],"sections":[],"technologies":["mr-linac","sbrt"],"targets":[],"drugs":["artera-ai-prostate"],"companies":[],"institutions":["ucla-jonsson"],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":["jama-oncology"],"dependsOn":[],"notes":[],"role":"Professor and Vice Chair of Clinical and Translational Research, Radiation Oncology, UCLA","institutionId":"ucla-jonsson","specialisms":["Prostate radiotherapy","MR-guided radiotherapy","Hypofractionation"],"profiles":[{"label":"UCLA profile","url":"https://www.uclahealth.org/providers?q=Amar%20U.%20Kishan"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Kishan%20AU%5BAuthor%5D"},{"label":"Google Scholar","url":"https://scholar.google.com/scholar?q=Amar%20U.%20Kishan"}],"papers":[{"title":"Magnetic Resonance Imaging-Guided vs Computed Tomography-Guided Stereotactic Body Radiotherapy for Prostate Cancer: The MIRAGE Randomized Clinical Trial","journal":"JAMA Oncology","year":2023,"url":"https://doi.org/10.1001/jamaoncol.2022.6558","doi":"10.1001/jamaoncol.2022.6558"},{"title":"Androgen deprivation therapy use and duration with definitive radiotherapy for localised prostate cancer: an individual patient data meta-analysis","journal":"Lancet Oncology","year":2022,"url":"https://doi.org/10.1016/S1470-2045(21)00705-1","doi":"10.1016/S1470-2045(21)00705-1"}]},"route":"/people/amar-kishan/","neighbours":{"cancer":[{"id":"prostate","kind":"cancer","name":"Prostate cancer","route":"/cancers/prostate/"}],"technology":[{"id":"mr-linac","kind":"technology","name":"MR-guided adaptive radiotherapy","route":"/technologies/mr-linac/"},{"id":"sbrt","kind":"technology","name":"SBRT / SABR (stereotactic radiotherapy)","route":"/technologies/sbrt/"}],"drug":[{"id":"artera-ai-prostate","kind":"drug","name":"ArteraAI Prostate","route":"/drugs/artera-ai-prostate/"}],"institution":[{"id":"ucla-jonsson","kind":"institution","name":"UCLA Jonsson Comprehensive Cancer Center","route":"/institutions/ucla-jonsson/"}],"journal":[{"id":"jama-oncology","kind":"journal","name":"JAMA Oncology","route":"/journals/jama-oncology/"}]}}
