Data Set for the Reporting of Ear and Temporal Bone Tumors: Explanations and Recommendations of the Guidelines From the International Collaboration on Cancer Reporting.

Arch Pathol Lab Med 2018 Nov 30. Epub 2018 Nov 30.

From the University of Sydney, Royal Prince Alfred Hospital, Camperdown, New South Wales, Australia (Dr Gupta); the Department of Head and Neck and Oral Pathology, Guy's Hospital, London, United Kingdom (Dr Sandison); the Department of Pathology, Moffitt Cancer Center, Tampa, Florida (Dr Wenig); and the Department of Pathology, Southern California Permanente Medical Group, Woodland Hills Medical Center, Woodland Hills (Dr Thompson).

The International Collaboration on Cancer Reporting (ICCR) was established to internationally unify and standardize the pathologic reporting of cancers based on collected evidence, as well as to allow systematic multi-institutional intercountry data collection to guide cancer care in the future. Such collaborative efforts are particularly essential for developing an evidence base for rare neoplasms, or those with marked geographic variation in incidence, such as the tumors of the ear and the temporal bone. The ear and the temporal bone, including the external auditory canal and the middle and inner ear, with the closely associated facial nerve, internal carotid artery, and internal jugular vein, is one of the most complex anatomic structures in the head and neck.

Temporal Bone Tumors: An Imaging Update.

Neuroimaging Clin N Am 2019 Feb;29(1):145-172

Department of Radiology, Massachusetts Eye and Ear Infirmary, Harvard Medical School, 243 Charles Street, Boston, MA 02114, USA.

In their variety, temporal bone tumors mirror the complexity of the structure from which they arise. They include more familiar lesions, such as vestibular schwannomas and paragangliomas, and also rarer neoplasms, such as nonvestibular schwannomas, sarcomas, giant cell tumors, Schneiderian papillomas, and endolymphatic sac tumors. Diagnostic imaging is invaluable in evaluating such lesions because they are typically challenging to access surgically and monitor clinically. Read More

Temporal patterns in the risk of chronic health conditions in survivors of childhood cancer diagnosed 1970-99: a report from the Childhood Cancer Survivor Study cohort.

Lancet Oncol 2018 Dec 8;19(12):1590-1601. Epub 2018 Nov 8.

Duke University School of Medicine, Durham, NC, USA.

Background: Treatments for childhood cancer have evolved over the past 50 years, with the goal of maximising the proportion of patients who achieve long-term survival, while minimising the adverse effects of therapy. We aimed to assess incidence patterns of serious chronic health conditions in long-term survivors of childhood cancer across three decades of diagnosis and treatment.

Methods: We used data from the Childhood Cancer Survivor Study, a retrospective cohort with longitudinal follow-up of 5-year survivors of common childhood cancers (leukaemia, tumours of the CNS, Hodgkin lymphoma, non-Hodgkin lymphoma, Wilms tumour, neuroblastoma, soft tissue sarcoma, or bone tumours) who were diagnosed before the age of 21 years and from 1970 to 1999 in North America.

Clinical application of radiation dose reduction for head and neck CT.

Eur J Radiol 2018 Oct 24;107:209-215. Epub 2018 Aug 24.

Department of Clinical Radiology, Kyushu University Graduate School of Medical Sciences, Fukuoka, Japan.

CT has advantages over MRI including rapid acquisition, and high spatial resolution for detailed anatomical information on the head and neck region. Therefore, CT is the first choice of imaging modality for the larynx, hypopharynx, sinonasal region, and temporal bone. Introduction of multi-detector CT (MDCT) scanning has allowed reduction in scan time, availability of isovoxel image, and relevant 3D image reconstruction; however, it leads to over-ranging due to helical scanning, and increased radiation dose due to 3D-volume imaging, and small detector size.
