Cancer stem cells in relation to treatment.

Jpn J Clin Oncol 2018 Dec 12. Epub 2018 Dec 12.

Department of Gastroenterological Surgery, Osaka University Graduate School of Medicine, Osaka, Japan.

The classical cancer therapies, including chemotherapy and radiation therapy, can initially show good results and tumor shrinkage; however, for most cancer patients disease recurrence is a common event. This tumor regrowth following therapy is now thought to depend on a small population of cancer stem cells (CSCs), which, similar to other stem cells, have the capacity for self-renewal and multipotent differentiation. Cancer stem cells have been identified based on cell surface protein expression in many tumor types, and for all diseases studied, this specific cell population is required for serial transplantation in animal models.

Thyroid Sequelae of Pediatric Cancer Therapy.

Horm Res Paediatr 2018 Dec 12:1-14. Epub 2018 Dec 12.

The hypothalamic-pituitary-thyroid axis is a common site of unintended, acquired disease either during or after the treatment of cancer. Children treated with external radiation therapy are at the highest risk for developing a thyroid-related late effect, but thyroid dysfunction and second primary thyroid neoplasms can also occur after treatment with radiopharmaceutical agents such as 131I-metaiodobenzylguanidine. Increasingly recognized is the development of early thyroid dysfunction as an off-target consequence of the more novel cancer therapeutics such as the tyrosine kinase inhibitors and immune checkpoint inhibitors.

Interior X-ray diffraction tomography with low-resolution exterior information.

Phys Med Biol 2018 Dec 12. Epub 2018 Dec 12.

College of Optics and Photonics, University of Central Florida, Orlando, Florida, 32816, UNITED STATES.

X-ray diffraction tomography (XDT) resolves spatially-variant XRD profiles within macroscopic objects, and provides improved material contrast compared to the conventional transmission-based computed tomography (CT). However, due to the small diffraction cross-section, XDT suffers from long imaging acquisition time, which could take tens of hours for a full scan using a table-top X-ray tube. In medical and industrial imaging applications, oftentimes only the XRD measurement within a region-of-interest (ROI) is required, which, together with the demand to reduce imaging time and radiation dose to the sample, motivates the development of interior XDT systems that scan and reconstruct only an internal region within the sample.

An evaluation of the consistency of shifts reported by three different systems for non-coplanar treatments.

J Radiosurg SBRT 2018 ;5(4):323-330

Department of Radiation Oncology, University of Utah, Salt Lake City, UT 84112, USA.

Treatment of intra-cranial lesions sometimes requires a non-coplanar beam configuration. One of the most commonly used IGRT modalities, kV conebeam CT, cannot typically be used when large couch rotations are introduced. However, multiple other systems allow for imaging/tracking the patient for such situations. Read More

Selective and super-selective C-arm based cone beam CT angiography (CBCTA) with DynaCT for CyberKnife radiosurgery planning of intracranial arteriovenous malformations (AVMs).

J Radiosurg SBRT 2018 ;5(4):305-313

Division of Radiation Oncology, University of Ottawa, Ottawa, ON, Canada.

Background: Successful radiosurgery for intracranial arteriovenous malformations (AVMs) requires accurate delineation of the nidus in 3D. Exact targeting and precise equipment is needed to achieve obliteration of the nidus while minimizing toxicity to the surrounding brain. In some micro-AVMs and poorly visible AVMs we have used cone beam CT angiography (CBCTA) with selective and super-selective angiography where a micro-catheter is advanced into the feeding arteries- to assist with nidus definition for CyberKnife radiosurgery planning.
