Clinical Outcomes of Intensity Modulated Proton Therapy Reirradiation for Gynecologic Malignancies

Advances in Radiation Oncology, 2023
Purpose: Pelvic reirradiation (re-RT) for patients with gynecologic cancers remains a challenge because of toxicity concerns. Given the dosimetric advantages of proton therapy, we aimed to assess oncologic and toxicity outcomes of patients with re-RT to ...

A Systematic Review of Proton Therapy for the Management of Nasopharyngeal Cancer [PDF]

International Journal of Particle Therapy, 2021
Purpose: With improved technology, more patients with nasopharyngeal cancer (NPC) are receiving definitive treatment with proton therapy, which allows greater sparing of dose to normal tissues without compromising efficacy. As there is no randomized data,

Post-Irradiation Sinus Mucosa Disease in Nasopharyngeal Carcinoma Patients Treated with Intensity-Modulated Proton Therapy

, 2022
In the past decade, patients with nasopharyngeal cancer (NPC) have been deemed candidates for proton radiotherapy, due to the large and comprehensive target volumes and the necessity for the retention of the surrounding healthy tissues. In this study, we
