A radiation oncologist, his specialisms are radiation oncology, intraoperative radiotherapy and proton therapy, alongside modern image-guided external beam techniques. He led ELIOT, the randomised phase 3 equivalence trial of intraoperative electron radiotherapy in early breast cancer, whose long-term recurrence outcomes were reported in The Lancet Oncology. His other papers include a study of seroconversion in patients with cancer and oncology health care workers infected by SARS-CoV-2, and a review of machine learning models for predicting toxicity outcomes in radiotherapy. His publications are listed on PubMed.","asOf":"2026-09-08","links":[{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Orecchia%20R%5BAuthor%5D%20intraoperative%20radiotherapy"}],"tags":[],"related":[],"cancers":[],"sections":[],"technologies":["imrt-igrt"],"targets":[],"drugs":[],"companies":[],"institutions":["ieo-milan"],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"role":"Scientific Director, IEO","institutionId":"ieo-milan","specialisms":["Radiation oncology","Intraoperative radiotherapy","Proton therapy"],"profiles":[{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Orecchia%20R%5BAuthor%5D%20intraoperative%20radiotherapy"}],"papers":[{"title":"Intraoperative irradiation for early breast cancer (ELIOT): long-term recurrence and survival outcomes from a single-centre, randomised, phase 3 equivalence trial","journal":"The Lancet Oncology","year":2021,"doi":"10.1016/s1470-2045(21)00080-2"},{"title":"Seroconversion in patients with cancer and oncology health care workers infected by SARS-CoV-2","journal":"Annals of Oncology","year":2021,"doi":"10.1016/j.annonc.2020.10.473"},{"title":"Machine Learning-Based Models for Prediction of Toxicity Outcomes in Radiotherapy","journal":"Frontiers in Oncology","year":2020,"doi":"10.3389/fonc.2020.00790"}]},"route":"/people/roberto-orecchia/","neighbours":{"technology":[{"id":"imrt-igrt","kind":"technology","name":"IMRT / IGRT (modern external beam)","route":"/technologies/imrt-igrt/"}],"institution":[{"id":"ieo-milan","kind":"institution","name":"IEO (European Institute of Oncology)","route":"/institutions/ieo-milan/"}]}}
