Hala Issa, MD1 , Hani Saleh, MD2, Mahdi Aljamal, MD1, and Ali Shakhshir, MD1 Abstract Oculoauriculovertebral dysplasia, also called Goldenhar syndrome, involves several issues, such as small ears (microtia), underdeveloped jaw (mandibular hypoplasia), skin growths near the eyes (epibulbar dermoids or lipodermoids), and problems with bones, heart, spine, and kidneys, among others. It is rarely associated with neuroblastoma. This report highlights a case where neuroblastoma was diagnosed in a child with Goldenhar syndrome, which, to the best of our knowledge, is the second case of its kind in the literature.

Este trabajo comparó la técnica Modulated Arc Therapy (mARC) con IMRT para la irradiación cerebral total con preservación hipocampal, siguiendo los criterios del protocolo RTOG 0933. Los resultados mostraron que IMRT logró ligeramente mejor conformidad del plan y menor dosis al hipocampo y otros órganos críticos. No obstante, la técnica mARC permitió reducciones significativas en el número de unidades monitoras y en el tiempo de tratamiento, lo que representa una ventaja operativa relevante. En conjunto, mARC se perfila como una alternativa técnicamente viable y eficiente para este tipo de tratamiento.
Este estudio evaluó la relación entre la distancia de contacto cardíaco (CCD) y la dosis máxima recibida por la arteria coronaria descendente anterior (LAD) en pacientes con radioterapia postmastectomía por cáncer de mama izquierdo. En una cohorte de 53 pacientes, se compararon planes con 3D-CRT, IMRT y VMAT. Se observó una correlación positiva entre la CCD y la dosis máxima a la LAD, lo que sugiere su utilidad como predictor anatómico de exposición coronaria. Asimismo, las técnicas moduladas mostraron mejor homogeneidad del plan y menor dosis cardíaca en comparación con la radioterapia conformal.

A B S T R A C T Background: One of the main technical challenges in craniospinal irradiation (CSI) is the risk of overdosing or underdosing in field overlap regions due to the need to match multiple treatment fields along the Planning Target Volume (PTV). To the authors’ knowledge, the technical and dosimetric feasibility of modulated arc therapy (mARC) has not yet been evaluated for CSI. Unlike other arc techniques, mARC delivers dose in discrete arcs. This study compared mARC with intensity-modulated radiation therapy (IMRT) and analyzed the impact of overlap region thickness, defined by the number of computed tomography (CT) slices, on plan quality. Methods: Treatment plans were generated for 10 patients using both mARC and IMRT on a Siemens Artiste linear accelerator. Optimization pseudo-structures were created with 4, 5, 6, and 7 tomographic slices at the craniothoracic and thoracolumbar junctions, resulting in eight plans per patient. The prescribed dose was 36 Gy in 20 fractions. Plans were evaluated by assessing PTV dosimetric parameters, doses to organs at risk (OARs), monitor units (MU), and treatment time. Statistical analysis employed two-way repeated-measures analysis of variance (ANOVA).
Abstract Background Cancer predisposition syndromes (CPSs) are inherited disorders that increase the risk of developing cancer from childhood through adulthood. They account for up to 10% of pediatric tumors, making early recognition important for reducing morbidity and mortality. Because these syndromes show variable penetrance and a wide range of clinical presentations even within the same family, identifying affected children can be challenging.
1. Introduction In recent years, the treatment paradigm for rectal cancer (RC) has increasingly shifted toward dose intensification strategies, aiming to enhance complete response (CR) rates [1,2]. Achieving CR is clinically meaningful, as it significantly increases the likelihood of organ preservation and functional sphincter-sparing outcomes—particularly critical in younger patients, for whom long-term quality of life (QoL) and avoidance of permanent colostomy are paramount [3,4] and older patients with comorbidities rendering them not suitable for surgery [5].
Introduction: Intensity Modulated Radiotherapy (IMRT) and Image Guided Radiotherapy (IGRT) have become an integral part of standard care for rectal cancer, but evidence-based detailed guidance is lacking to support its clinical implementation and use. This European SocieTy for Radiotherapy and Oncology (ESTRO) technical guideline aimed to assess the available evidence and provide recommendations for their use in rectal cancer treatment.

The precise definition of target volumes in radiotherapy represents one of the most critical steps in radiation treatment planning, directly impacting treatment efficacy and patient safety. The International Commission on Radiation Units and Measurements (ICRU) has established standardized terminology and protocols through a series of reports (ICRU 50, 62, 71, and 83) to ensure consistency across radiotherapy centers worldwide.
The palliative care team has been asked to see a 5-year-old boy in the pediatric intensive care unit (PICU) with hypoxic ischemic encephalopathy secondary to a drowning episode 3 years ago. The child is ventilation-dependent, and this is the fifth admission for recurrent pneumonia this year. The family has been very clear about their goals of care but do not feel supported by the medical team
As a leading organization in radiation oncology, the American Society for Radiation Oncology (ASTRO) is dedicated to improving quality of care and patient outcomes. A cornerstone of this goal is the development and dissemination of clinical practice guidelines based on systematic methods to evaluate and classify evidence, combined with a focus on patient-centric care and shared decision-making. ASTRO develops and publishes guidelines without

Recent developments in radiation and neuro-oncology provide the ability to deliver required radiation dose to target volumes for pediatric brain tumors while avoiding sensitive normal central nervous system (CNS) structures uninvolved by tumor. Many CNS target volumes are smaller than in previous years due to better understanding of areas at risk for recurrence or involvement and patterns of spread for a given diagnoses. Advances in neuroimaging and treatment planning software allow for better delineation of tumors and normal neuroanatomy

Lattice Radiation Therapy (LRT) is an innovative radiotherapy (RT) technique that allows to concurrently administering ablative doses inside neoplastic lesions and low doses near the adjacent organs at risks (OARs) (See Fig. 1). LRT can be considered as a type of spatially fractionated radiation therapy (SFRT) and it represents the 3-dimensional (3D) configuration of the 2-dimensional (2D) GRID therapy (See Fig. 2) [1]. The heterogeneous dose distribution of a LRT plans entails the creation of a 3D array inside the planning target volume (PTV), where high-dose (vertices or hotspots) and low-dose areas (periphery
While COG and Euronet use three risk groups (low, intermediate, and high), the authors chose to dichotomize groups as most included articles categorized patients as limited or advanced disease. Low- and intermediate-risk (IR) diseases in studies describing three risk groups were analyzed within the limited disease group. Each study had their own criteria for risk stratification. Two sets of bias assessments were conducted, using methodologies used by the Pediatric Normal Tissue Effects in Clinic
The consensus was discussed during monthly webbased national meetings, and the algorithms were revised until a consensus was achieved. Results: A total of 26 participants were involved in the development of the algorithms. Two treatment algorithms are proposed, one for the initiation of treatment and one for the discontinuation of treatment.
Background: Prostate cancer (PCa) is the most common malignant tumor in men in Mexico. There are two treatments with curative potential, such as radical prostatectomy (RP) for localized disease and radical radiotherapy (R-RT). Control rates are determined by the prognostic factors present. Objective: The objective of this study was to determine the control and survival rate with radical conformal radiotherapy (R-CR) in PCa. Methods: The 8.5-year results of an institutional series are presented using Cox proportional hazards analysis and Kaplan-Meier survival.
Childhood cancer is prevalent throughout the world.1 With modern technologies and therapies, high-income countries (HICs) now report cure rates as high as 80% for children with cancer.2,3 However, low- and middle-income countries (LMICs) struggle with lack of health care resources and infrastructure, resulting in upward of 90% of pediatric oncologic deaths occurring in these countries.2-4 As radiotherapy is a critical component of care for children with malignancies, improving quality and access to pediatric radiotherapy services in LMICs is vital.5 Ethiopia is a low-income country (LIC) in sub-Saharan Africa with a multitude of distinct ethnic groups, languages, and religions
El cáncer es la tercera causa de muerte en México con más de 91,500 fallecimientos anuales. Uno de cada dos pacientes requiere radioterapia como parte de su tratamiento, pero nuestro país cuenta con apenas 2 equipos por millón de habitantes, cuando la recomendación internacional es de 4. Esto coloca a México en desventaja incluso frente a países de ingresos bajos.
Introduction: Post-treatment surveillance is recommended for NSCLC owing to a high risk of recurrence, but evidence on the optimal surveillance method is lacking. This trial evaluates fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography ([18F]FDG PET/CT) versus contrast-enhanced CT (ceCT) for surveillance in patients with NSCLC.

Purpose: Plasma Epstein−Barr virus (EBV) DNA is a widely used biomarker for nasopharyngeal carcinoma (NPC). Prior investigations predominantly assessed EBV DNA at a single time point, thus neglecting the differential prognostic implications of the temporal clearance pattern of EBV DNA during induction-concurrent (chemo)radiation therapy (RT).

The definitive management of many pediatric malignancies requires radiation therapy (RT) to the central nervous system (CNS) that may predispose survivors to neurologic complications. A detailed understanding of radiation dosevolume effects is required to maximize the therapeutic ratio of brain irradiation.
Treatment protocols for childhood cancer have changed rapidly over the years, maintaining a balance between effective therapy and acceptable toxicity.
As cancer survival rates continue to improve, longterm adverse effects of treatment on health and quality of life are increasingly important considerations for clinicians, patients, and familymembers. Neurocognitive deficits (NCD) are well established as a common adverse effect in brain tumor survivors, owing to the tumor itself, but also localized brain irradiation treatment.

Abstract: Radiation therapy, a common treatment for central nervous system cancers, can negatively impact cognitive function, resulting in radiation-induced cognitive decline (RICD). RICD involves a decline in cognitive abilities such as memory and attention, likely due to damage to brain white matter, inflammation, and oxidative stress
Simple Summary: Radiation therapy-related brain damage with neurocognitive impairment is a common long-term side effect in cancer survivors and significantly impairs the quality of life. Increasing evidence indicates the increased vulnerability of the developing brain to the neurotoxic effects of ionizing radiation (IR).
Abstract: The brain undergoes ionizing radiation (IR) exposure in many clinical situations, particularly during radiotherapy for malignant brain tumors. Cranial radiation therapy is related with the hazard of long-term neurocognitive decline.
