CANADIAN JOURNAL OF OPHTHALMOLOGY 2024; 59:209-217. [PMID: 36921624 DOI: 10.1016/j.jcjo.2023.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Accepted: 02/15/2023] [Indexed: 03/13/2023]
Abstract
Conjunctival melanoma, a rare malignancy of the ocular surface, is increasing in incidence. When small, straightforward excision with "no touch" surgery and cryotherapy at an experienced centre can provide excellent outcomes. When advanced, management is more complex and highly individualized. The risk of metastatic disease from conjunctival melanoma is as high as 30% and depends on tumour origin, American Joint Committee on Cancer (AJCC) classification, biomarkers, and perhaps most important, management technique. Metastatic disease can result in melanoma-associated death. Therefore, early detection and prompt directed treatment at an experienced centre are important for protection from metastasis. In this review, we provide an update on conjunctival melanoma clinical features, diagnostic modalities, AJCC staging, genetic markers, and the most critical, controlled management with minimization of tumour seeding. We detail the new era of characterization of conjunctival melanoma with molecular biomarkers that predict melanoma prognosis. This could lead to precision medicine with targeted approaches to specific mutations that improve patient survival. As we work together, the field of conjunctival melanoma is moving forward.

Abstract
Identification of potential key targets of melanoma, a fatal skin malignancy, is critical to the development of new cancer therapies. Lysine methyltransferase 2A (KMT2A) promotes melanoma growth by activating the human telomerase reverse transcriptase (hTERT) signaling pathway; however, the exact mechanism remains elusive. This study aimed to reveal new molecular targets that regulate KMT2A expression and melanoma growth. Using biotin-streptavidin-agarose pull-down and proteomics, we identified Damage-specific DNA-binding protein 2 (DDB2) as a KMT2A promoter-binding protein in melanoma cells and validated its role as a regulator of KMT2A/hTERT signaling. DDB2 knockdown inhibited the expression of KMT2A and hTERT and inhibited the growth of melanoma cells in vitro. Conversely, overexpression of DDB2 activated the expression of KMT2A and promoted the growth of melanoma cells. Additionally, we demonstrated that DDB2 expression was higher in tumor tissues of patients with melanoma than in corresponding normal tissues and was positively correlated with KMT2A expression. Kaplan-Meier analysis showed a poor prognosis in patients with high levels of DDB2 and KMT2A. Overall, our data suggest that DDB2 promotes melanoma cell growth through the transcriptional regulation of KMT2A expression and predicts poor prognosis. Therefore, targeting DDB2 may regulate the effects of KMT2A on melanoma growth and progression, providing a new potential therapeutic strategy for melanoma.

Abstract
PURPOSE To report new indications for deep temporalis fascia (DTF) grafts in the ophthalmic field. METHODS Monocentric retrospective interventional case series study. All the patients who underwent a DTF graft in an unpublished new indication over the study period (May 2020-October 2023) were included. For each patient, gender, age, graft indication, outcomes, complications, and follow-up duration were collected. In most cases, the DTF graft was covered by a vascularized flap. RESULTS Eight patients underwent a DTF graft over the study period. The indications were: radiotherapy-induced scleral necrosis in three cases, tendinoplasty to replace the inferior rectus muscle tendon invaded by a locally advanced conjunctival carcinoma in one case, Ahmed glaucoma valve tube exposure in one case, intraocular lens with scleral fixation exposure in one case, orbital cerebrospinal fluid fistula (orbitorrhea) in one case, and post-traumatic complete corneal graft loss in one case. The DTF graft was successful in 87.5% of cases after a mean follow-up of 11.4 months. No complications were observed. CONCLUSIONS DTF graft is a highly versatile graft that can be easily harvested. New indications for DTF grafts may include the repair of radiotherapy-induced scleral necrosis, the creation of oculomotor tendon and the temporary packing of large ocular tissue loss in an emergency context. Further studies with a longer follow-up are needed to confirm our preliminary results.

Abstract
The development of immune checkpoint inhibitors (ICI) has transformed the treatment of advanced-stage cutaneous melanoma; however, most trials did not include patients with conjunctival melanoma. Herein the authors describe a patient with recurrent conjunctival melanoma who developed locally advanced, b-raf and v-raf murine sarcoma viral oncogene homolog B1-negative melanoma in her nasal cavity and extensive, metabolically active, bilateral lymphadenopathy in her thorax. Her nasal mass measured 4.3 × 1.7 cm and was determined to be unresectable. She was treated with 4 cycles of combination ipilimumab and nivolumab therapy followed by maintenance nivolumab. She experienced a dramatic treatment response with a reduction in the size of her nasal mass to 3.0 × 1.1 cm and a complete resolution of her adenopathy. She then underwent complete surgical resection of her residual mass (approximately 75% of her original tumor size) and remains melanoma-free at 1 year of follow-up. Given the underlying genetic similarities of conjunctival melanoma to cutaneous melanoma, providers should consider the use of neoadjuvant immune checkpoint inhibitors for patients with locally advanced or limited metastatic disease.

Abstract
OBJECTIVES To identify the risk factors of orbital exenteration and to evaluate the prognosis of exenterated patients with conjunctival melanoma (CM). METHODS 79 consecutive CM patients treated at our centre from January 2000 to September 2021 were included. The demographic, clinical and pathological characteristics were compared between eye-sparing patients and orbital exenteration patients. Main outcomes including progression-free survival (PFS), distant metastasis-free survival (DFS) and disease specific survival (DSS) were assessed in exenterated patients. RESULTS The mean follow-up period was 46 ± 39 months. Risk factors for orbital exenteration were identified as worse cT category (OR, 50.75; 95% CI, 5.40-477.07; P = 0.001) and greater tumour thickness (OR, 1.27; CI, 1.04-1.55; P = 0.02). Of the 32 patients who underwent orbital exenteration, three (9.4%) had local recurrence; six (18.8%) experienced regional metastasis; sixteen (50.0%) suffered distant metastasis and fifteen (46.9%) died of metastatic disease. In patients who received orbital exenteration, palpebral conjunctiva involvement (PFS: P < 0.01; DFS: P < 0.05; DSS: P = 0.04), histological ulceration (PFS: P = 0.03; DFS: P = 0.01; DSS: P = 0.03) and regression (PFS: P = 0.01; DFS: P < 0.01; DSS: P = 0.04) were identified as risk factors for poor prognosis. Caruncle involvement (P = 0.01) was also associated with increased risk of melanoma related mortality in exenterated patients. CONCLUSIONS Histopathological factors should be taken into account when formulating surgical plans for orbital exenteration and when evaluating patients' prognosis following exenteration. For CM patients with caruncle or palpebral conjunctiva involvement, orbital exenteration should be considered for unresectable disease.

Abstract
Background In recent years, new therapeutic options to overcome the mechanisms of tumor immune suppression be effective in the treatment of cutaneous melanoma. These approaches have also been applied in ocular melanoma. The aim of this study is to present the current status and research hotspots of immunotherapy for ocular melanoma from a bibliometric perspective and to explore the field of immunotherapy for malignant ocular melanoma research. Methods In this study, the Web of Science Core Collection database (WoSCC) and Pubmed were selected to search the literature related to immunotherapy of ocular melanoma. Using VOSviewer, CiteSpace, the R package "bibliometrix," and the bibliometric online platform through the construction and visualization of bibliometric networks, the country/region, institution, journal, author, and keywords were analyzed to predict the most recent trends in research pertaining to ocular melanoma and immunotherapy. Results A total of 401 papers and 144 reviews related to immunotherapy of ocular melanoma were included. The United States is the main driver of research in the field, ranking first in terms of the number of publications, total citations, and H-index. The UNIVERSITY OF TEXAS SYSTEM is the most active institution, contributing the most papers. Jager, Martine is the most prolific author, and Carvajal, Richard is the most frequently cited author. CANCERS is the most published journal in the field and J CLIN ONCOL is the most cited journal. In addition to ocular melanoma and immunotherapy, the most popular keywords were "uveal melanoma" and "targeted therapy". According to keyword co-occurrence and burst analysis, uveal melanoma, immunotherapy, melanoma, metastases, bap1, tebentafusp, bioinformatics, conjunctival melanoma, immune checkpoint inhibitors, ipilimumab, pembrolizumab, and other research topics appear to be at the forefront of this field's research and have the potential to remain a hot research topic in the future. Conclusion This is the first bibliometric study in the last 30 years to comprehensively map the knowledge structure and trends in the field of research related to ocular melanoma and immunotherapy. The results comprehensively summarize and identify research frontiers for scholars studying immunotherapy associated with ocular melanoma.

Abstract
PURPOSE Conjunctival melanoma (CM) is a rare and aggressive malignancy. Global studies demonstrate increased burden of disease in countries with high rates of cutaneous melanoma. There are currently no reports on CM incidence, trends, or survival within Aotearoa-New Zealand (NZ), a country with the highest global rates of cutaneous melanoma, which this study aims to address. DESIGN This was a retrospective review using the national cancer registry. METHODS Data on histologically confirmed CM diagnosed between January 1, 2000, and December 31, 2020, were obtained from the NZ Cancer Registry. Cases were identified using the International Classification of Disease, 10th edition (ICD-10) codes. Primary outcome measures were age-standardized incidence, trends, and survival. RESULTS A total of 68 CM cases were identified. There was a preponderance for females (n=40, 58.8%) and CM predominantly affected European patients (n=63, 92.6%). Median follow-up was 5.0 years [interquartile range (IQR)=2.4-9.9 y] and the median age at diagnosis was 68.5 years (IQR=57.0-79.0 y), with non-Europeans presenting at a significantly younger age [-17.3 y (95% CI: -31.3 to -3.2), P =0.019] than Europeans. The annual age-adjusted incidence(±SD) was 0.6±0.2 cases per million population per year with a stable incidence trend over 21 years. All-cause mortality was found in 28 cases (41.2%) and the median time to death was 3.76 years (IQR=2.1-5.7 y). Five-year all-cause survival and disease-specific survival was 69% and 90%, respectively. CONCLUSIONS This is the first report on CM incidence, trends, and mortality in NZ. The CM burden is in line with European and North American data, despite NZ having the highest rate of cutaneous melanoma. The incidence remained stable over 2 decades.

Abstract
Ophthalmic malignancies include various rare neoplasms involving the conjunctiva, the uvea, or the periocular area. These tumors are characterized by their scarcity as well as their histological, and sometimes genetic, diversity. Uveal melanoma (UM) is the most common primary intraocular malignancy. UM raises three main challenges highlighting the specificity of ophthalmic malignancies. First, UM is a very rare malignancy with an estimated incidence of 6 cases per million inhabitants. Second, tissue biopsy is not routinely recommended due to the risk of extraocular dissemination. Third, UM is an aggressive cancer because it is estimated that about 50% of patients will experience metastatic spread without any curative treatment available at this stage. These challenges better explain the two main objectives in the creation of a dedicated UM biobank. First, collecting UM samples is essential due to tissue scarcity. Second, large-scale translational research programs based on stored human samples will help to better determine UM pathogenesis with the aim of identifying new biomarkers, allowing for early diagnosis and new targeted treatment modalities. Other periocular malignancies, such as conjunctival melanomas or orbital malignancies, also raise specific concerns. In this context, the number of biobanks worldwide dedicated to ocular malignancies is very limited. The aims of this article were (i) to describe the specific challenges raised by a dedicated ocular malignancy biobank, (ii) to report our experience in setting up such a biobank, and (iii) to discuss future perspectives in this field.

Abstract
BACKGROUND Melanoma is a highly aggressive neoplasm with a high degree of malignancy and rapid acquisition of resistance by cancer cells. METHODS Biological studies of a series of isoxazole compounds with immunomodulatory properties were preceded by in silico analysis. The assay evaluated the viability of NHDF and A375 cell cultures after the administration of isoxazole compounds after a 24-hour incubation period in the MTT test. Analyzes of ROS and NO scavenging, P-glycoprotein activity, and properties were performed. The levels of Caspase 3 and Caspase 9 were measured using ELISA to assess which pathways induced apoptosis by the tested compounds. On the chip, the synergistic effect of doxorubicin and the most active compound from the MM9 series on cells of the A375 melanoma line was determined. RESULTS All tested N'-substituted derivatives of 5-amino-N,3-dimethyl-1,2-oxazole-4-carbohydrazide with immunomodulatory activity show multidirectional antitumor activity on A375 melanoma lines with an affinity for P-glycoprotein, induction of free radical formation and generation of DNA damage leading to the death of cancer cells, as well as formation of complexes with DNA Topoisomerase II. Most of the tested compounds show pro-apoptotic activity. The most active compound in the series induces apoptosis in three distinct pathways and acts synergistically with doxorubicin. CONCLUSIONS The most active compound with immunomodulatory properties showed multidirectional antitumor activity against cells of the A375 melanoma line and also had a synergistic pro-apoptotic effect with doxorubicin, which may result in a reduction of this cytostatic dose with increased effectiveness.
