Simulation of Focal Boosting in Online Adaptive MRI-Guided SBRT for Patients With Locally Advanced Prostate Cancer With Seminal Vesicle Involvement
To evaluate the feasibility and accuracy of focal boosting in online adaptive MRI-guided stereotactic body radiation therapy (SBRT) for patients with prostate cancer (PCa) with seminal vesicle invasion (T3b) by analyzing the impact of intrafraction motion on the dose planned for the gross tumor volume (GTV) and clinical target volume (CTV).
Use of Magnetic Resonance Imaging for Postoperative Radiation Therapy Planning in Patients with Carbon Fiber-Reinforced Polyetheretherketone Instrumentation
Carbon fiber-reinforced polyetheretherketone (CFR-PEEK) instrumentation is being used more frequently in the spinal oncology landscape. Better visualization with this material allows for more precise postoperative stereotactic body radiation therapy (SBRT) planning using either computed tomography (CT)-myelography or magnetic resonance imaging (MRI) studies. We compared the dosimetric planning equivalencies and outcomes.
Neurostimulators and Radiation Therapy: Is There Any Risk?
The use of neurostimulators has increased in recent decades. However, safety guidelines in patients undergoing radiation therapy (RT) are lacking. We report 2 cases of pelvic RT for prostate cancer in patients with spinal cord neurostimulators. The implantable pulse generator was placed close to the irradiated volume in the gluteal region and received a median and maximal dose of 2.8 and 5.68 Gy, respectively for patient 1; and 3.65 and 5.15 Gy, respectively for patient 2. During and after RT, No dysfunction of the device was recorded. Based on the similarity with the cardiac implantable electric devices, we recommend similar safety procedures, this include the following: (i) a cumulative dose <5 Gy, (ii) avoiding neutron-producing RT, (iii) ensuring the implantable pulse generator positioning outside the direct beams, (iv) switching the device to "off-mode" during treatment delivery, and (v) in vivo verification in case of implantable pulse generator close to irradiation volume. The final decision should involve neurology specialist.
Radiotherapy for Graves' Ophthalmopathy: When is the Optimal Timing of Treatment and Evaluation
Despite the decades of using radiotherapy for Graves' ophthalmopathy, the effects and optimal timing remain unclear. We retrospectively analyzed to evaluate the overall efficacy and response, predictive factors, and the effective timing of radiotherapy by assessing steroid requirement after radiotherapy in patients without prior surgery.

Radiation Therapy for Heterotopic Ossification: A Systematic Review
Heterotopic Ossification (HO) is a benign disorder characterized by ectopic bone formation in soft tissues that can lead to functional loss in patients. We conducted a systematic review of the evidence on the use of Radiation Therapy (RT) for the prevention or treatment of HO.
Management of Dry Mouth Toxicity Following Lu-PSMA-617 Radioligand Therapy
Treatment options for patients with metastatic castration-resistant prostate cancer include the use of radioligand therapy with Lu-PSMA-617. Although Lu-PSMA-617 can selectively target prostate cancer cells, salivary glands express PSMA on the apical lumen of the acinar epithelium. Xerostomia resulting from the use of radioligand therapy is common. Herein, we report on a case of a Common Terminology Criteria for Adverse Events version 5 grade 2 dry mouth event after administration of Lu-PSMA-617. The patient was managed with oral hygiene and xerostomia mitigation strategies using oral rinses.
Consensus Guidelines for Delineation of Clinical Target Volumes for Intensity-Modulated Radiotherapy for Intact Cervical Cancer: An Update
Accurate target delineation is essential when using intensity-modulated radiotherapy (IMRT) for intact cervical cancer. In 2011, the Radiation Therapy Oncology Group (RTOG) published a consensus guideline using magnetic resonance imaging (MRI). The current project expands on the previous atlas by including computed tomography (CT)-based contours, contours with MRI and positron- emission- tomography (PET) registrations, the addition of common and complex scenarios, and to incorporate information on simulation and treatment planning techniques.
Best practice guidelines for use of reference points in radiation oncology information systems to aggregate longitudinal dosimetric data
Tracking patient dose in radiation oncology is challenging due to disparate electronic systems from various vendors. Treatment planning systems (TPS), radiation oncology information systems (ROIS), and electronic health records (EHR) lack uniformity, complicating dose tracking and reporting. To address this, we examined practices in multiple radiation oncology settings and proposed guidelines for current systems.
Financial Toxicity and Quality-of-Life Outcomes on a Phase 1 5-fraction Stereotactic Partial Breast Irradiation Protocol for Early-Stage Breast Cancer
We report the financial toxicity and quality-of-life outcomes of our prospective phase 1 dose-escalation study of 5-fraction stereotactic partial breast irradiation (S-PBI) for early-stage breast cancer.
Radiation Therapy for Rectal Cancer: An ASTRO Clinical Practice Guideline Focused Update
With the results of several recently published clinical trials, this guideline focused update provides evidence-based recommendations for the indications and dose-fractionation regimens for neoadjuvant radiation therapy (RT), optimal sequencing of RT and systemic therapy in the context of total neoadjuvant therapy (TNT), and considerations for selective omission of RT and surgery for rectal cancer.
Radiation Therapy for the Treatment of Osteoarthritis
Osteoarthritis is a common cause of pain and disability in the United States. Many patients experience pain that is refractory or unable to be treated by traditional treatments such as exercise, physical therapy, nonsteroidal anti-inflammatory drugs, and/or cyclooxygenase-2 inhibitors. For patients with medically refractory disease, intra-articular corticosteroid therapy, hyaluronic acid, or surgery can be considered. However, for many older patients with significant impairment in quality of life related to osteoarthritis, radiation therapy is a noninvasive treatment option that has a long history of global use. In this topic discussion, we review the clinical evidence supporting treatment of osteoarthritis, as well as considerations for how to select which patient and joint to treat. We discuss technical considerations for treatment including dose and immobilization, assessment of treatment response, and the role of retreatment.
Appropriateness Criteria for Radiation Therapy in the Setting of Presumed Early-Stage Lung Cancer
Low-dose chest computed tomography imaging for lung cancer screening is revealing increasing numbers of radiographic early-stage lung cancers. This topic discussion describes when a clinical scenario merits radiation therapy without a histologic diagnosis, with an emphasis on pragmatic algorithms in settings without readily available advanced biopsy techniques.
Dose Planning and Radiation Optimization for Thoracic Conventional, Twice Daily, and Stereotactic Radiation Therapy: A Delphi Consensus from a National Survey of Practitioners
We sent surveys to a large number of radiation oncologists with active thoracic cancer practices and applied the Delphi method over 3 rounds to generate consensus DVH metrics. We used these results to create consensus-based OAR dose constraint and target goal templates for practical implementation.
Management of de novo Metastatic Hormone-Sensitive Prostate Cancer (mHSPC) and the role of Radiation Therapy: A Consensus by the Italian Association of Radiotherapy and Clinical Oncology (AIRO)
Prostate cancer treatments paradigms are in continuous evolution, especially in the metastatic setting. In this context, the Genito-Urinary Group of Italian Association of Radiotherapy and Clinical Oncology aimed to create a consensus on radiation therapy indication in de novo metastatic hormone-sensitive prostate cancer both on primary tumor and metastatic sites.
Reducing Patient Care Delays in Radiation Oncology Via Optimization of Insurance Pre-Authorization: Reducing Delays via Optimization of Pre-Auth
Difficulties and delays in insurance pre-authorization (pre-auth) can negatively impact patient care, resulting in postponing, modifying, or even cancelling radiation therapy for patients. We aimed to perform a root cause analysis for pre-auth delays in our department and implement solutions to optimize our workflow. Our primary objectives were to decrease mean time for clinical treatment plan (CTP) completion, and for number of cases delayed/denied, by 50% each.
