The Role of Inflammation in Ocular Tumours

2016-09-21 20:23:22 | BioPortfolio

Summary

This prospective, non-therapeutic study will determine whether a novel imaging technique can identify presumptive tumour associated macrophages (TAMs) in patients with ocular tumours.

In this study, we will modify the standard angiography protocol by having patients return twice in the week following angiography for additional photographs. Photographs will be obtained 2-7 days after angiography, but without further injection of dye. This technique contrasts with normal angiography in which photographs are taken during the transit phase of dye circulation and in the minutes thereafter. Of note, both the dye and the cameras used for its detection have been approved for clinical use for several decades and are routinely used in the evaluation of patients with ocular tumours.

We will evaluate 5 groups:

1. Choroidal nevus (low-risk features): requires distinction from melanoma through diagnostic testing

2. Choroidal indeterminate melanocytic lesion (high-risk features): requires diagnostic testing for identification and distinction from nevus and melanoma

3. Choroidal melanoma: requires confirmation of diagnosis and evaluation for potential metatstases

4. Suspected metastatic tumour (ie, primary tumour elsewhere): requires identification of primary tumour

5. Locally treated ocular tumours: requires followup to evaluate response to treatment and potential change or repeat therapy

Medical and Biotech [MESH] Definitions

An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

Experimentally induced tumor that produces MELANIN in animals to provide a model for studying human MELANOMA.

The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS. Loosely, it refers to ocular adjustments for VISION, OCULAR at various distances. (Cline et al., Dictionary of Visual Science, 4th ed)

A cellular subtype of malignant melanoma. It is a pigmented lesion composed of melanocytes occurring on sun-exposed skin, usually the face and neck. The melanocytes are commonly multinucleated with a "starburst" appearance. It is considered by many to be the in situ phase of lentigo maligna melanoma.
