Differential diagnosis of myopic choroidal neovascularization (mCNV): insights from multimodal imaging and treatment implications.

Purpose: The aim of this article is to conduct a comprehensive systematic review about the current understandings and differential diagnosis of myopic choroidal neovascularization (mCNV) and other several similar diseases, describing their multimodal imaging analysis, prognostic implications, and current types of management.

Methods: This systematic review was performed based on a search on the PubMed database of relevant papers regarding mCNV and other entities discussed in the paper, according to our current knowledge.

Results: Through the integration of a multimodal imaging approach, especially optical coherence tomography (OCT), along with accurate demographic and clinical assessment, it becomes possible to effectively differentiate mCNV from similar yet heterogeneous entities.

Characterizing Different Multidisciplinary Team Models Implemented Within One Comprehensive Cancer Center.

Background: The multidisciplinary approach is considered "best practice" in oncology. Multidisciplinary Teamwork (MDTW) can be broadly classified into Multidisciplinary Team Meetings (MDTM) and Multidisciplinary Cancer Clinics (MDCC; involving also patients), yet both models are heterogeneously implemented.

Purpose: This study aims at describing the different MDTW implemented models in a Comprehensive Cancer Center.

Materials And Methods: We report on a 51-year-old woman with Vogt-Koyanagi-Harada-like syndrome, which occurred while she was undergoing treatment with dabrafenib and trametinib for cutaneous melanoma. The patient complained of sudden, bilateral vision loss of 2 days' duration.

Vitreoretinal Surgery in the Prevention and Treatment of Toxic Tumour Syndrome in Uveal Melanoma: A Systematic Review.

Toxic tumour syndrome (TTS) is a particularly aggressive form of secondary vasculopathy occurring after radiation therapy of uveal melanoma due to the persistence of the necrotic tumour mass inside the eye. The development of TTS confers a particularly unfavourable functional and anatomical ocular prognosis, ultimately requiring enucleation in most cases if untreated. Vitreoretinal (VR) surgery has been successfully applied for treatment and prevention of TTS using both resecting and non-resecting techniques.

Liquid Biopsy and Radiological Response Predict Outcomes Following Discontinuation of Targeted Therapy in Patients with BRAF Mutated Melanoma.

Survival in Patients With Sentinel Node-Positive Melanoma With Extranodal Extension.

Background: Prognostic parameters in sentinel node (SN)-positive melanoma are important indicators to identify patients at high risk of recurrence who should be candidates for adjuvant therapy. We aimed to evaluate the presence of melanoma cells beyond the SN capsule-extranodal extension (ENE)-as a prognostic factor in patients with positive SNs.

Methods: Data from 1,047 patients with melanoma and positive SNs treated from 2001 to 2020 at the Istituto Nazionale dei Tumori in Milano, Italy, were retrospectively investigated.

Iatrogenic Ocular Surface Diseases Occurring during and/or after Different Treatments for Ocular Tumours.

The ocular surface represents a finely regulated system that allows the protection of the eye. It is particularly susceptible to different treatments for intraocular tumours, such as uveal melanoma and conjunctival cancers. Traditionally, the management of ocular tumours depends on the characteristics of the lesion, and is based on a combination of selective surgery, topical chemotherapy, and/or radiotherapy delivered through different mechanisms (e.

Curcuma-Based Nutritional Supplement in Patients with Neovascular Age-Related Macular Degeneration.

To investigate effectiveness and safety of a curcumin-based nutritional supplement in neovascular age-related macular degeneration (AMD). We conducted a controlled retrospective study, reviewing the medical records of patients referred to the Eye Center, Humanitas Hospital, Bergamo due to neovascular AMD and treated with antivascular endothelial growth factor (VEGF) intravitreal injections (IVIs) and oral administration of a curcumin-based nutritional supplement vehiculated by enterosoma-I. We retrospectively collected data of 18 naive patients who received IVI and daily oral nutritional supplement and 24 naive age-matched controls with the same diagnosis undergoing only IVI.

Local tumour control and radiation side effects for fractionated stereotactic photon beam radiotherapy compared to proton beam radiotherapy in uveal melanoma.

Purpose: To compare the adverse side effects of fractionated stereotactic photon beam radiotherapy (fSRT) with proton beam radiotherapy (PBR) in patients with uveal melanoma (UM).

Methods: A retrospective study investigating 306 UM patients treated with fSRT (N=153) by the Rotterdam Ocular Melanoma Study group (ROMS), The Netherlands, between 1999-2014 or with PBR (N=153) at the Royal Liverpool University Hospital and the Clatterbridge Cancer Centre, Bebington, United Kingdom, between 1993-2014. The tumours treated with fSRT were matched with tumours treated with PBR based on sex, left or right eye, TNM classification, posterior margin ≤ or > 3mm of the fovea and of the optic disc.

Optic disc drusen: a systematic review : Up-to-date and future perspective.

Background: Optic disc drusen (ODD) are acellular deposits in the prelaminar optic nerve head. The most accredited theory is that they are secondary to abnormalities in axonal metabolism and degeneration, but the pathogenesis is not clear to date.

Clinical Manifestation: Although ODD are often considered a benign condition, the great majority of patients with ODD show visual field defects and are at higher risk for developing anterior ischemic optic neuropathy.

Prognostic biopsy of choroidal melanoma: an optimised surgical and laboratory approach.

Background: Accurate survival prognostication for patients with uveal melanoma (UM) enables effective patient counselling and permits personalised systemic surveillance for the early detection of metastases and, in high-risk patients, enrolment in any trials of systemic adjuvant therapy. The aim of this work is to determine the success of prognostic UM tumour biopsy using an improved surgical approach and optimised sample handling workflow.

Methods: Patients with UM treated by primary radiotherapy between 2011 and 2013 and who underwent a prognostic biopsy with cytology, multiplex ligation-dependent probe amplification and/or microsatellite analysis were included.

In-depth proteomic profiling of the uveal melanoma secretome.

Uveal melanoma (UM), the most common primary intraocular tumour in adults, is characterised by a high frequency of metastases to the liver, typically with a fatal outcome. Proteins secreted from cancer cells ('secretome') are biologically important molecules thought to contribute to tumour progression. We examined the UM secretome by applying a label-free nanoLCMS/MS proteomic approach to profile proteins secreted into culture media by primary UM tumours with a high- (HR; n = 11) or low- (LR; n = 4) metastatic risk, compared to normal choroidal melanocytes (NCM) from unaffected post-mortem eyes.

Culturing Uveal Melanoma Cells.

A major challenge in cancer research is the use of appropriate models with which to study a specific biological question. Cell lines have long been used to study cellular processes and the effects of individual molecules because they are easy to use, grow rapidly, produce reproducible results and have a strong track record in research. In uveal melanoma in particular, the absence of animal models that faithfully replicate the behavior of the human disease has propagated the generation and use of numerous cell lines by individual research groups.

The Effect of Temperature Changes in Vitreoretinal Surgery.

Purpose: Recent studies on temperature control in biology and medicine have found the temperature as a new instrument in healthcare. In this manuscript, we reviewed the effects of temperature and its potential role in pars plana vitrectomy. We also examined the relationship between intraocular pressure, viscosity, and temperature in order to determine the best balance to manipulate the tamponades during the surgery.
