Pui Ying Chan, Peter Hall, Gordon Hay, Victoria M L Cohen, Peter W Szlosarek
The use of immune checkpoint inhibition has led to major improvements in outcome for patients with metastatic cutaneous melanoma. The combination of ipilimumab and nivolumab has demonstrated greater activity over single agent immunotherapy in phase III trials. Clinical trials of combination CTLA-4 and PD-1 inhibition are underway in uveal melanoma, for which there are currently no data. Here, we present the case of a 74-year-old male patient with metastatic uveal melanoma, who was treated with a combination of ipilimumab and nivolumab...

The authors present the case of a 59-year-old woman in treatment with interferon alfa-2b for stage IV melanoma and widespread metastases who presented with interferon-associated retinopathy. An ocular examination revealed multiple retinal cotton-wool spots and hard exudates. Interferon treatment was suspended. The patient was followed up for 5 months following the baseline visit by means of en face optical coherence tomography (OCT), spectral-domain OCT, and OCT angiography. Multimodal imaging was useful in the follow-up of this condition, permitting the characterization of all the lesions hallmarking the interferon-retinopathy and showing that this illness was related to a reduction of the retinal vascular perfusion...

Ipilimumab binds and blocks cytotoxic T-lymphocyte-associated antigen-4, causing enhanced T-cell reaction, antitumor response, and significant improvement of the overall survival of patients with metastatic melanoma. Patients treated with ipilimumab can develop immune-related adverse effects, primarily dermatitis, colitis, hepatitis, and hypophysitis. Although, in phase I-III studies, 64.2% of all patients suffered from immune-related adverse effects, ocular adverse effects occurred in 1.3% only. In the cases reported below, 2 patients with metastatic melanoma developed severe ocular myositis after treatment with ipilimumab...

Bcl-2-associated athanogene 3 (BAG3), a co-chaperone of heat shock protein 70 (HSP70), exerts anti-apoptotic effects in various malignant tumors. However, relationships between choroidal melanoma and BAG3 are poorly studied. This study investigated the expression of BAG3 in a case of human choroidal melanoma. Funduscopy, computed tomography, and single-photon emission computed tomography with the intravenous injection of N-isopropyl-p-[(123)I] iodoamphetamine strongly indicated choroidal melanoma in a 68-year-old woman...

Orbital exenteration is a disfiguring procedure performed for unresponsive orbital infections and control of recurrent benign tumours and malignancies arising from the eyelids (basal cell carcinoma, squamous cell carcinoma, conjunctival malignant melanoma), lachrymal glands (adenoid cystic carcinoma) or surrounding sinuses. In extremely rare cases the use of a prosthetic eye after enucleation can lead to anophthalmic socket tumours. We report the case of a 54-year-old man who had left eye enucleation due to recurring events of retinal detachment and who developed an invasive fast growing epidermoid carcinoma 30 years later...

Background Malignant melanoma is the most common cancer of the eye in adults that originates either in the intra-ocular uveal tract or extra-ocular conjunctiva. Although the primary tumor can be treated successfully, no effective therapy for both metastatic conjunctival and uveal melanoma currently exits. Tumor-associated lymphangiogenesis and immune cell infiltration play a pivotal role in the development and therapeutic targeting of metastases. Project description Here, we provide an overview of current translational research on lymphangiogenesis and its therapeutic inhibition as well as modulation of immune cell infiltration by passive and active immunotherapy in melanoma of the eye...

Limbal Stem Cells are a unique cell line located at the corneal limbus. They are responsible for regenerating and restoring corneal epithelial layers. Limbal stem cell transplantation is a promising technique that has been used to treat several hereditary and acquired corneal diseases. Cornea tissue lack vascularity. Hence, there were no special restrictions on collecting ocular tissues from donors with a diagnosis of metastatic melanoma. We are reporting a case of a patient who developed an ocular melanoma after she had limbal stem cell transplantation from a donor with history of melanoma...

INTRODUCTION: Percutaneous hepatic perfusion (PHP) with melphalan is an effective treatment for patients with hepatic metastases, but associated with high rates of bone marrow depression. To reduce systemic toxicity, improvements have been made to the filtration system. In pre-clinical studies, the Delcath System's GEN2 filter was superior to the first-generation filters. In this clinical study, we analysed the pharmacokinetics and toxicity of PHP using the new GEN2 filter. METHODS AND MATERIALS: Starting February 2014, two prospective phase II studies were initiated in patients with hepatic metastases from ocular melanoma or colorectal cancer...
