Patients With Head/Neck Cancer See Lower Stroke Risk With Initial Surgery
(MedPage Today) -- In oropharyngeal squamous cell carcinoma (OPSCC), the type of initial treatment appears to influence the likelihood of stroke in the years afterward, researchers said. A population-based study of U.S. veterans treated for OPSCC...

Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

Cerebellar Stroke and Leptomeningeal Carcinomatosis following Cement Leakage into the Vertebral Artery during Cervical Vertebroplasty
This report describes an unusual vertebral artery cement embolization during C3 transpedicular vertebroplasty performed under computed tomography (CT) guidance and fluoroscopy. The Institutional Review Board approved this case report, and the patient ’s consent for publication was obtained. A 54-year-old woman with an invasive lobular breast carcinoma suffered from cervical pain. A CT scan showed spinal osteolytic lesions. A thoracic vertebral biopsy confirmed the diagnosis of breast cancer metastasis.

CT diagnostic reference levels based on clinical indications: results of a large-scale European survey
ConclusionsThis is the first study reporting on feasibility of establishing CT DRLs based on CI using European data. Resulting values will serve as a baseline for comparison with local radiological practice, national authorities when DRLs are set/updated, or as a guideline for local DRL establishment.Key Points•First study reporting on the feasibility of establishing CT diagnostic reference levels based on clinical indication using data collected across Europe.•Only one-fourth of the hospitals had CT machines less than 5 years old.•Large dose variations were observed among hospitals and CT protocols were quite differ...

Carotid Sparing Conformal Radiotherapy for Early Larynx Cancer
Parallel opposed lateral (POL) portals have been adopted as the mainstay radiation therapy technique for early-stage carcinoma of the glottis. Although the use of POL has been associated with excellent control rates and tolerability, the partial inclusion of carotid arteries (CAs) in the high dose regions of the fields has been shown to lead to an increased long-term risk of carotid stenosis and hemorrhagic stroke. Many researchers have proposed the utilization of three-dimension conformal therapy (3DCRT) or Intensity-modulated radiation therapy (IMRT) as viable carotid-sparing techniques via reductions to the mean and max...

Endovascular aspiration to treat acute ischemic stroke caused by embolic carcinoma.
We report a rare case of large-cell, high-grade neuroendocrine lung cancer embolus occluding the basilar artery, which likely detached into the bloodstream from the lung after intruding into a pulmonary vein. The embolus was treated with endovascular aspiration, and achieved modified Thrombolysis In Cerebral Infarction 2c revascularization. After initial neurological recovery, the patient suffered respiratory arrest and support was withdrawn 48 h later. We discuss the tumor characteristics and implications for treatment of acute ischemic stroke in patients with cancer diagnoses. PMID: 30786802 [PubMed - as supplied by publisher]

A nomogram for the prediction of cerebrovascular disease among patients with brain necrosis after radiotherapy for nasopharyngeal carcinoma
In various cancer populations, radiotherapy is associated with the development of vascular disease [1 –4]. Previous studies have established an increased incidence of carotid stenosis (CAS) and ischemic stroke in patients with head and neck cancer treated with radiotherapy [4,5]. A study of 6862 patients (age>65  years) showed that five-year incidence of cerebrovascular events was 19% in patients treated with radiotherapy alone compared with 14% in patients treated with surgery plus radiotherapy; the corresponding ten-year incidence were 34% and 25%, respectively [4].

Stroke after Radiotherapy for Head and Neck Cancer – What is the Risk?
Treating head and neck squamous cell carcinomas with radiotherapy has been shown to cause damage to the cerebrovasculature. This retrospective cohort study found that any exposure to radiation was associated with a 46% higher hazard of stroke, and with radiotherapy as the sole treatment modality, 70% increased risk of stroke compared to surgery alone. Implications of this research speak to the need for adequate follow-up and survivorship care among patients that were treated with RT.

Detection of a Right Carotid Focus of 18F-FDG Predicted an Ischemic Stroke
AbstractA 60-year-old woman was referred into our department for staging of an endometrial carcinoma. In addition to peritoneal and nodes metastases, 18F-FDG PET/CT showed a calcified plaque of the right carotid with focal uptake. One month later, the patient presented left hemiparesis, suggesting a right hemisphere stroke. MRI confirmed frontal infarction in the anterior cerebral artery territory. 18F-FDG is suggested to be a valuable tool to detect vessel wall inflammation; detection of focal arterial uptake on PET/CT suggests unstable plaque and requires urgent patient’s management to prevent vascular events in a popu...

Impact of post operative intensity modulated radiotherapy on acute gastro-intestinal toxicity for patients with endometrial cancer: Results of the phase II RTCMIENDOMETRE French multicentre trial.
CONCLUSION: In accordance with our hypothesis, post-operative IMRT resulted in a low rate (less than 30%) of acute GI grade 2 toxicity, in patients with endometrial carcinomas. At W15, no patient demonstrated a grade 2 adverse event, and the prevalence of remaining grade 1 events was less than 20%. PMID: 24630537 [PubMed - as supplied by publisher]
