Severe, Fatal Methotrexate-related Neurotoxicity in 2 Adolescent Patients With ALL
Neurotoxicity is a well-documented adverse effect of methotrexate in the treatment of pediatric cancers. The spectrum of symptoms is broad, can include stroke-like episodes and seizures, and classically resolves within days. The majority of patients tolerate subsequent doses without recurrence of symptoms. The population of patients who experience persistent and irreversible neurologic symptoms is poorly described, with the existing literature suggestive of a relationship with radiation therapy. The authors present a case series of 2 patients with pre-B-cell acute lymphoblastic leukemia who developed severe and ultimately ...

Vascular events from carotid artery atherosclerosis after radiation therapy for laryngeal and hypopharyngeal cancer: the incidence and risk factors.
Authors: Makita C, Okada S, Kajiura Y, Tanaka O, Asahi Y, Yamada N, Yanagida M, Kumagai M, Murase S, Ito M, Kumano T, Matsuo M Abstract In this retrospective cohort study, we evaluated the incidence of vascular events from carotid artery atherosclerosis after radiotherapy indication for laryngeal and hypopharyngeal cancer. From January 2007 to December 2016, we investigated 111 laryngeal/hypopharyngeal cancer patients who underwent curative radiotherapy and were followed up for ≥1 year (median follow-up duration, 60 months). We evaluated the incidence of vascular events from carotid artery atherosclerosis, define...

Outcomes of Combined Antegrade –Retrograde Dilations for Radiation-Induced Esophageal Strictures in Head and Neck Cancer Patients
AbstractThe purpose of this study is to analyze outcomes of combined antegrade –retrograde dilations (CARD). This retrospective study was conducted on 14 patients with a history of head and neck cancer, treated with radiation therapy that was complicated by either complete or near-complete esophageal stenosis. All patients had minimal oral intake and depended on a gastrostom y tube for nutrition. Swallow function before and after CARD was assessed using the Functional Oral Intake Scale, originally developed for stroke patients and applied to head and neck cancer patients. Patients undergoing CARD demonstrated a quantifia...

Intracranial long-term complications of radiation therapy: an image-based review
ConclusionsWe describe the clinical and imaging features of selected sequelae of intracranial radiation therapy, with a focus on those most relevant to practicing radiologists. Knowledge of these complications and their imaging findings is important, because radiologists play a key role in early detection of these entities.

SMART Syndrome Identification and Successful Treatment
We report a 41-year-old male patient admitted to our emergency room with a reduced level of consciousness and global aphasia. One month prior to admission, he started with frequent headache attacks of moderate intensity and paroxysmal behavioral alterations, advancing to confusion, gait instability, language impairment, and somnolence. He had a history of medulloblastoma treated with surgical resection followed by craniospinal irradiation 21 years before symptom onset. After excluding more frequent causes for the patient ’s symptoms along with a suggestive image pattern, we started treatment for SMART syndrome with high-...

Stroke-Like Migraine Attacks After Radiation Therapy (SMART) Syndrome: A Comprehensive Review
AbstractPurpose of ReviewSMART syndrome is a delayed complication of cranial irradiation that can be misconstrued as tumor recurrence or some other intracranial neurological disease. Recognition of this clinical syndrome is imperative as it can obviate the need for invasive diagnostic testing and can provide reassurance to both the patient and their loved ones.Recent FindingsSMART syndrome is generally considered a reversible clinical syndrome; however, neurological deficits may become permanent. Pathophysiology of SMART syndrome may involve cerebrovascular autoregulation impairment, neuronal dysfunction leading to trigemi...

Relationship between 7T MR-angiography features of vascular injury and cognitive decline in young brain tumor patients treated with radiation therapy
ConclusionsArterial volume is reduced with increasing CMB presence and is influenced by the total brain volume exposed to radiation. This work highlights the potential use of vascular-derived metrics as non-invasive markers of treatment-induced injury and cognitive impairment in pediatric brain tumor patients.

Late vascular complications after cranial radiotherapy: A report of two illustrative cases
We present two cases of late neurological complications after CRT and briefly discuss its diagnosis and their shared pathophysiological aspects. The first case is a patient with cognitive impairment associated to mineralizing microangiopathy ten years after CRT for nasopharyngeal carcinoma and the second one is a woman with Stroke-like Migraine Attacks after Radiation Therapy (SMART) syndrome two years after CRT for anaplastic meningioma. Nowadays, higher survival rates might cause an increase in appearance of late neurological complications after CTR. These reported cases show that late complications can mimic a wide vari...

ERLEADA ® (apalutamide) Oral Presentations Demonstrate Importance of Prostate Specific Antigen (PSA) as Key Efficacy Indicator and Show Strong Patient Adherence Rates
September 11, 2021 (RARITAN, N.J.) – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new data demonstrating robust prostate-specific antigen (PSA) response and strong adherence rates in patients with non-metastatic castration-resistant prostate cancer (nmCRPC) treated with ERLEADA® (apalutamide) in the real-world clinical setting. The strong PSA response was also seen in a separate post-hoc analysis that showed a correlation between rapid and deep PSA response and prolonged survival in both metastatic castration-sensitive prostate cancer (mCSPC) and nmCRPC. The post-hoc analysis also suppor...

New ERLEADA ® (apalutamide) Analysis Demonstrates Rapid, Deep Prostate-Specific Antigen (PSA) Response in Patients with Metastatic Castration-Sensitive Prostate Cancer (mCSPC)
SAN FRANCISCO, Feb. 14, 2022 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new real-world evidence data showing the initiation of ERLEADA® (apalutamide) results in high rates of rapid and deep prostate-specific antigen (PSA) response among patients with metastatic castration-sensitive prostate cancer (mCSPC). In a separate post-hoc analysis of the registrational Phase 3 SPARTAN and TITAN studies, rapid and deep PSA responses with ERLEADA® were associated with improvement in patient-reported outcomes (PROs) related to quality of life, physical wellbeing, pain, and fatigue intensity. The...
