Potential of Aqueous Humor as a Liquid Biopsy for Uveal Melanoma.

Int J Mol Sci 2022 Jun 2;23(11). Epub 2022 Jun 2.

The Vision Center at Children's Hospital Los Angeles, Los Angeles, CA 90027, USA.

Tumor biopsy can identify prognostic biomarkers for metastatic uveal melanoma (UM), however aqueous humor (AH) liquid biopsy may serve as an adjunct. This study investigated whether the AH of UM eyes has sufficient circulating tumor DNA (ctDNA) to perform genetic analysis. This is a case series of 37 AH samples, taken before or after radiation, and one tumor wash sample, from 12 choroidal and 8 ciliary body (CB) melanoma eyes. Read More

Laser Treatment for Choroidal Melanoma: Current Concepts.

Surv Ophthalmol 2022 May 26. Epub 2022 May 26.

Department of Ocular Tumor, Orbital Disease and Ophthalmic Radiation Therapy, The New York Eye Cancer Center, 115 East 61st Street, New York City, New York, USA, 10065.

Laser treatment has offered a relatively nonsurgical alternative for eye, life, and vision-sparing treatment of malignant melanoma of the choroid. Historically, the most commonly used forms of lasers were xenon-arc, argon laser, krypton laser, and the more recent transpupillary thermotherapy (TTT) and photodynamic therapy (PDT). Melanomas selected for laser treatment tend to be smaller and visibly accessible, which means these tumors are usually located in the posterior choroid. Read More

Surgical Approach in Intraocular Tumors

Turk J Ophthalmol 2022 04;52(2):125-138

Ankara University Faculty of Medicine, Department of Ophthalmology, Ankara, Turkey

Surgery in intraocular tumors is done for excision/biopsy and the management of complications secondary to the treatment of these tumors. Excision/biopsy of intraocular tumors can be done via fine-needle aspiration biopsy (FNAB), transretinal biopsy (TRB), partial lamellar sclerouvectomy (PLSU), and endoresection. FNAB, TRB, and PLSU can be used in tumors that cannot be diagnosed by clinical examination and other ancillary testing methods. Read More

The rationale for treating uveal melanoma with adjuvant melatonin: a review of the literature.

BMC Cancer 2022 Apr 13;22(1):398. Epub 2022 Apr 13.

Department of Clinical Neuroscience, Division of Eye and Vision, St. Erik Eye Hospital, Karolinska Institutet, 171 64, Stockholm, Sweden.

Background: Uveal melanoma is a rare form of cancer with high mortality. The incidence of metastases is attributed to early seeding of micrometastases from the eye to distant organs, primarily the liver. Once these seeded clusters of dormant tumor cells grow into larger radiologically detectable macrometastases, median patient survival is about 1 year. Read More

Fundus Autofluorescence Imaging in Patients with Choroidal Melanoma.

Cancers (Basel) 2022 Apr 2;14(7). Epub 2022 Apr 2.

Department of Ophthalmology, DRK Kliniken Berlin Westend, 14050 Berlin, Germany.

Choroidal melanocytic lesions require reliable and precise clinical examination and diagnosis to differentiate benign choroidal nevi from choroidal melanoma, as the latter may become life-threatening through metastatic disease. To come to an accurate diagnosis, as well as for monitoring, and to assess the efficacy of therapy, various imaging modalities may be used, one of which is non-invasive fundus autofluorescence (FAF) imaging using novel high-resolution digital imaging technology. FAF imaging is based on the visualization of intrinsic fluorophores in the ocular fundus. Read More

Melanoma Res 2022 06 8;32(3):192-199. Epub 2022 Apr 8.

Department of Ophthalmology, University Hospital, LMU Munich.

Plaque brachytherapy is the most common procedure for the treatment of small choroidal melanoma, especially in posteriorly located tumors. However, there is only little information on outcome after treatment with stereotactic radiosurgery, for example, CyberKnife radiosurgery. We reviewed patients with choroidal melanoma (maximum tumor height 4 mm) treated with CyberKnife radiosurgery. Read More

Longitudinal optical coherence tomography angiography (OCT-A) in a patient with radiation retinopathy following plaque brachytherapy for uveal melanoma.

Am J Ophthalmol Case Rep 2022 Jun 25;26:101508. Epub 2022 Mar 25.

Free Radical and Radiation Biology Program, Department of Radiation Oncology, University of Iowa, Iowa City, IA, USA.

Purpose: Patients with choroidal melanoma treated with brachytherapy lose vision over time due to radiation retinopathy and optic neuropathy. Newer imaging modalities such as optical coherence tomography angiography (OCT-A) may provide further insight into the ultrastructural vascular changes that occur over time. We studied the progressive OCT-A derived reduction in capillary density that occurred in the macula and juxtapapillary region of a patient treated with plaque brachytherapy for posterior uveal melanoma.

Department of Ophthalmology and Visual Sciences, University of Michigan, Kellogg Eye Center, Ann Arbor, Michigan, USA.

Introduction: Prognosis of uveal melanoma (UM) is assessed using clinical staging or molecular testing. Two modalities often used for prognostication are the American Joint Committee on Cancer (AJCC) staging and a tumor gene expression profile (GEP), the outcomes of which are often discordant. This article discusses a total risk score created to combine the discordant information from both sources. Read More

The Prognostic Relevance of PMCA4 Expression in Melanoma: Gender Specificity and Implications for Immune Checkpoint Inhibition.

Int J Mol Sci 2022 Mar 19;23(6). Epub 2022 Mar 19.

Department of Thoracic Surgery, University Medicine Essen-Ruhrlandklinik, 45239 Essen, Germany.

PMCA4 is a critical regulator of Ca homeostasis in mammalian cells. While its biological and prognostic relevance in several cancer types has already been demonstrated, only preclinical investigations suggested a metastasis suppressor function in melanoma. Therefore, we studied the expression pattern of PMCA4 in human skin, nevus, as well as in primary and metastatic melanoma using immunohistochemistry. Read More
