Uveal melanoma is the most common intraocular tumour in adults, it is a form of cancer that affects mostly older adults, as the average age at detection of this tumour is 60 years, but it can occur in any age group with no significant gender difference. However, uveal melanoma is very rare in children compared to the adult population, accounting for 1 % of all cases. In pediatric patients, malignant uveal melanoma is more frequently manifested during puberty, leading to speculation of an association between uveal melanoma and growth hormone levels. Prognostic factors for uveal melanoma include tumour histology, chromosomal abnormalities, tumour size, extrascleral spread and tumour location. Risk factors for uveal melanoma include melanocytosis, neurofibromatosis type 1 and dysplastic naevus syndrome. Some studies point to a significantly lower risk of developing metastases in younger patients, but the prognosis of uveal melanoma in children is not yet fully known. Clinical signs and treatment options for malignant uveal melanoma in children are still under discussion. Differential diagnosis of uveal lesions in children can sometimes be very difficult, as evidenced by following case report in which authors describe a case of choroidal melanoma in a 15-year-old girl.

Uveal melanoma (UM) poses a significant lethality, with approximately 50% of those developing metastases surviving less than one year. In the progression of UM, vasculogenic mimicry (VM) induced by hypoxia plays a pivotal role, which also partially explains the resistance of UM to anti-angiogenic therapies. Nevertheless, the crucial molecular mechanisms underlying VM in the progression of UM remain unclear.

NF1 encodes the multifunctional tumour suppressor protein, neurofibromin, which is best known for its causative role in Neurofibromatosis type 1 and in regulating MAPK signaling. Neurofibromin, in a context-specific manner, is involved in various tumorigenic processes, including those in melanocytes. This study investigated whether NF1 loss can collaborate with oncogenic GNAQ to promote melanoma in the dermis or eyes, where the G alpha q pathway is almost always activated.

BRM (SMARCA2) and BRG1 (SMARCA4) are mutually exclusive ATPase subunits of the mSWI/SNF (BAF) chromatin remodeling complex. BAF is an attractive therapeutic target because of its role in transcription, and mutations in the subunits of BAF are common in cancer and neurological disorders. Herein, we report the discovery of compound () as a potent allosteric inhibitor of the dual ATPase subunits from a high-throughput screening hit with a BRM IC of ∼27 μM.

Background: Proton beam therapy (PBT) has been gradually introduced for treating choroidal melanoma. This study systematically reviewed clinical reports to evaluate the efficacy and safety of PBT in choroidal melanoma patients.
Methods: This systematic review included all the primary studies involving PBT for choroidal melanoma patients through April 2024.

Objectives: This systematic review is aimed to evaluate the efficacy and safety of robotic Cyberknife radiotherapy (CKRT) in the treatment of uveal melanoma (UM).
Methods: Clinical studies published in English that assessed the efficacy and safety of robotic CKRT in UM were systematically searched in PubMed, Web of Science, Cochrane and Embase from inception to July 2023. Studies reporting extraocular tumours or other radiosurgery approaches were excluded.
