OverviewAI-generated summary
R.J. Megahed's research focuses on head and neck cancers, with a particular emphasis on re-irradiation strategies and spatially fractionated radiotherapy. Megahed has investigated the utilization of postoperative radiation therapy for medullary thyroid cancer and explored the outcomes of interstitial brachytherapy for soft tissue sarcomas. Additionally, Megahed's work includes the evaluation of dosimetric variations in head and neck cancer patients treated with intensity modulated proton therapy and liver-sparing total body irradiation for relapsed acute lymphoblastic leukemia. Megahed has authored 16 publications, with an h-index of 2 and 14 total citations, and collaborates with researchers at the University of Arkansas for Medical Sciences, including Santanu Samanta, Mumtaz Patel, and Gary D. Lewis.
