An Integrative Medicine Educational Program for Radiation Oncology Patients: Patient-Reported Outcomes.

Purpose: Complementary health approaches (CHAs) equip patients to self-manage radiation therapy (RT)-related symptoms and fulfill unmet needs, but few disclose CHA use to their radiation oncologist. An integrative medicine educational program (IMEP) was developed to assess its ability to improve patient self-efficacy for symptom management and CHA use disclosure.

Methods And Materials: The IMEP included 4 1-hour sessions covering topics of (1) meditation, (2) yoga, (3) massage therapy, and (4) nutrition.

Immune checkpoint inhibition and single fraction stereotactic radiosurgery in brain metastases from non-small cell lung cancer: an international multicenter study of 395 patients.

Purpose: Approximately 80% of brain metastases originate from non-small cell lung cancer (NSCLC). Immune checkpoint inhibitors (ICI) and stereotactic radiosurgery (SRS) are frequently utilized in this setting. However, concerns remain regarding the risk of radiation necrosis (RN) when SRS and ICI are administered concurrently.

Practical Implementation of Emergent After-Hours Radiation Treatment Process Using Remote Treatment Planning on Optimized Diagnostic CT Scans.

The purpose of this report is to present the implementation of a process for after-hours radiation treatment (RT) utilizing remote treatment planning based on optimized diagnostic computed tomography (CT) scans for the urgent palliative treatment of inpatients. A standardized operating procedure was developed by an interprofessional panel to improve the quality of after-hours RT and minimize the risk of treatment errors. A new diagnostic CT protocol was created that could be performed after-hours on hospital scanners and would ensure a reproducible patient position and adequate field of view.

Concurrent Administration of Immune Checkpoint Inhibitors and Single Fraction Stereotactic Radiosurgery in Patients With Non-Small Cell Lung Cancer, Melanoma, and Renal Cell Carcinoma Brain Metastases.

Purpose: Stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICI) are highly effective treatments for brain metastases, particularly when these therapies are administered concurrently. However, there are limited data reporting the risk of radiation necrosis (RN) in this setting.

Methods And Materials: Patients with brain metastases from primary non-small cell lung cancer, renal cell carcinoma, or melanoma treated with SRS and ICI were considered.

Concurrent Administration of Immune Checkpoint Inhibitors and Stereotactic Radiosurgery Is Well-Tolerated in Patients With Melanoma Brain Metastases: An International Multicenter Study of 203 Patients.

Background: Melanoma brain metastases are commonly treated with stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICIs). However, the toxicity of these 2 treatments is largely unknown when administered concurrently.

Objective: To evaluate the risk of radiation necrosis (RN) with concurrent and nonconcurrent SRS and ICIs.

Imaging-defined necrosis after treatment with single-fraction stereotactic radiosurgery and immune checkpoint inhibitors and its potential association with improved outcomes in patients with brain metastases: an international multicenter study of 697 patients.

Objective: Immune checkpoint inhibitors (ICIs) and stereotactic radiosurgery (SRS) are commonly utilized in the management of brain metastases. Treatment-related imaging changes (TRICs) are a frequently observed clinical manifestation and are commonly classified as imaging-defined radiation necrosis. However, these findings are not well characterized and may predict a response to SRS and ICIs.

Radiation necrosis in renal cell carcinoma brain metastases treated with checkpoint inhibitors and radiosurgery: An international multicenter study.

Background: Patients with renal cell carcinoma (RCC) brain metastases are frequently treated with immune checkpoint inhibitors (ICIs) and stereotactic radiosurgery (SRS). However, data reporting on the risk of developing radiation necrosis (RN) are limited.

Methods: RN rates were compared for concurrent therapy (ICI/SRS administration within 4 weeks of one another) and nonconcurrent therapy with the χ test.

Clinical and radiologic outcomes after stereotactic radiosurgery for meningiomas in direct contact with the optic apparatus: an international multicenter study.

Objective: Resection of meningiomas in direct contact with the anterior optic apparatus carries risk of injury to the visual pathway. Stereotactic radiosurgery (SRS) offers a minimally invasive alternative. However, its use is limited owing to the risk of radiation-induced optic neuropathy.

Stereotactic radiosurgery for clinoid meningiomas: a multi-institutional study.

Purpose: Resection of clinoid meningiomas can be associated with significant morbidity. Experience with stereotactic radiosurgery (SRS) for clinoid meningiomas remains limited. We studied the safety and effectiveness of SRS for clinoid meningiomas.

Survival impact of angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists in head and neck cancer.

Background: Preclinical evidence suggests a link between the renin-angiotensin system and oncogenesis. We aimed to explore the impact of angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB) in head and neck cancer (HNC).

Methods: Over 5000 patients were identified from the Surveillance, Epidemiology, and End Results-Medicare linked dataset and categorized according to ACEi and ARB and diagnoses of chronic kidney disease (CKD) or hypertension (HTN).

Stereotactic Radiosurgery for Perioptic Meningiomas: An International, Multicenter Study.

Background: Stereotactic radiosurgery (SRS) is increasingly used for management of perioptic meningiomas.

Objective: To study the safety and effectiveness of SRS for perioptic meningiomas.

Methods: From 12 institutions participating in the International Radiosurgery Research Foundation (IRRF), we retrospectively assessed treatment parameters and outcomes following SRS for meningiomas located within 3 mm of the optic apparatus.
