Therapy of uveal melanoma A Review.

Cesk Slov Oftalmol 2020 ;1(Ahead of print):1-13

The aim of intraocular melanoma therapy is to achieve local tumor control, reduce the risk of metastasis development, preserve the eyeball and possibly the visual function of the eye. The choice of therapeutic approach requires a comprehensive view and individual approach to each patient with uveal melanoma. Factors considered include local finding (location, tumor size and shape, tumor activity, central visual acuity, intraocular complications), age and the patients overall physical and psychological condition, as well as the patients wishes.

A Combined Neutron and Proton Regimen for Advanced Salivary Tumors: Early Clinical Experience.

Cureus 2021 May 4;13(5):e14844. Epub 2021 May 4.

Department of Radiation Oncology, University of Washington, Seattle, USA.

Background and objective  Fast neutron radiotherapy (NRT) is a high linear energy transfer (LET) particle therapy that offers a local control (LC) advantage over low-LET X-rays in the treatment of advanced and unresectable salivary gland malignancies. However, in tumors approximating the base of skull (BOS), target volumes may be underdosed to minimize toxicity to the central nervous system (CNS). In this setting, a proton beam boost to the underdosed part of the tumor may improve LC. Read More

Locoregional Flap Reconstruction Following Oromaxillofacial Oncologic Surgery in Dogs and Cats: A Review and Decisional Algorithm.

Front Vet Sci 2021 21;8:685036. Epub 2021 May 21.

Dentistry and Oromaxillofacial Surgery Unit, Department of Surgery, ADVETIA Centre Hospitalier Vétérinaire, Vélizy-Villacoublay, France.

Primary treatment of most oromaxillofacial tumors in dogs and cats is resective surgery. Management of malignant tumors may be very challenging as wide/radical free-margin surgical removal must be achieved while preserving vital functions. Removal of orofacial tumors may result in large defects exposing the oral cavity or creating a communication with the nasal, pharyngeal, or orbital cavities. Read More

NAD(P)H Quinone Oxidoreductase-1 in Organ and Tumor Tissues: Distinct Activity Levels Observed with a Benzo-rosol-Based Dual-Excitation and Dual-Emission Probe.

Anal Chem 2021 May 13;93(20):7523-7531. Epub 2021 May 13.

Department of Chemistry, Pohang University of Science and Technology, Pohang 37673, South Korea.

NAD(P)H quinone oxidoreductase-1 (NQO1), a protective enzyme against cellular oxidative stress, is expressed abnormally high in solid tumors and thus recognized as a cancer biomarker. To develop a fluorescent NQO1 probe with practicality, we investigated benzo-rosol fluorophores linked with a known self-immolative quinone substrate. Four probe candidates exhibited ratiometric sensing behavior toward the enzyme, satisfying our orbital mismatch stratagem proposed before, under dual-excitation and dual-emission conditions that alleviate the spectral overlap issue commonly observed with the ratiometric probes based on intramolecular charge-transfer change.

Orbital malignant schwannoma and embryonal rhabdomyosarcoma in rats caused by leakage of locally injected nickel subsulfide to the orbit.

J Toxicol Pathol 2021 Apr 27;34(2):151-156. Epub 2021 Feb 27.

Veterinary Pharmacology and Toxicology Laboratory, Graduate School of Veterinary Sciences, Iwate University, 3-18-8 Ueda, Morioka, Iwate 020-0066, Japan.

Nickel subsulfide (NiS) is known to induce intraocular neoplasms when injected intravitreally into the eyes of rats. Here, we found two extraocular orbital neoplasms in two different rat strains, presumably due to the leakage of locally injected NiS to the extraocular orbital tissues. In the F344/DuCrlCrlj rat, an orbital mass arose at 30 weeks after injection, and invaded into the cranium. Read More

Ectropion Uveae in neurofibromatosis type 1: a new manifestation.

Clin Ter 2021 05;172(3):206-208

Dermatologic Clinic, "Sapienza" University of Rome, Rome, Italy.

Abstract: Neurofibromatosis type 1 (NF1) is a rare genetic disorder with an autosomal dominant transmission and an estimated incidence of 1:2500-3500 live birth. Penetrance is virtually 100%, but the expression is highly variable and almost every organ can be affected. Diagnosis of NF1 is made with at least two of the following diagnostic criteria: six or more cafè-au-lait spots, two neurofibromas or one plexiform neurofibroma, axillary or groin freckling, optic glioma, two Lisch nodules, bone dysplasia and first-degree relative with NF1.
