Invasive Treatment Strategy for Older Patients with Myocardial Infarction.

BACKGROUND: Whether a conservative strategy of medical therapy alone or a strategy of medical therapy plus invasive treatment is more beneficial in older adults with non-ST-segment elevation myocardial infarction (NSTEMI) remains unclear. METHODS: We conducted a prospective, multicenter, randomized trial involving patients 75 years of age or older with NSTEMI at 48 sites in the United Kingdom. The patients were assigned in a 1:1 ratio to a conservative strategy of the best available medical therapy or an invasive strategy of coronary angiography and revascularization plus the best available medical therapy. Patients who were frail or had a high burden of coexisting conditions were eligible. The primary outcome was a composite of death from cardiovascular causes (cardiovascular death) or nonfatal myocardial infarction assessed in a time-to-event analysis. RESULTS: A total of 1518 patients underwent randomization; 753 patients were assigned to the invasive-strategy group and 765 to the conservative-strategy group. The mean age of the patients was 82 years, 45% were women, and 32% were frail. A primary-outcome event occurred in 193 patients (25.6%) in the invasive-strategy group and 201 patients (26.3%) in the conservative-strategy group (hazard ratio, 0.94; 95% confidence interval [CI], 0.77 to 1.14; P = 0.53) over a median follow-up of 4.1 years. Cardiovascular death occurred in 15.8% of the patients in the invasive-strategy group and 14.2% of the patients in the conservative-strategy group (hazard ratio, 1.11; 95% CI, 0.86 to 1.44). Nonfatal myocardial infarction occurred in 11.7% in the invasive-strategy group and 15.0% in the conservative-strategy group (hazard ratio, 0.75; 95% CI, 0.57 to 0.99). Procedural complications occurred in less than 1% of the patients. CONCLUSIONS: In older adults with NSTEMI, an invasive strategy did not result in a significantly lower risk of cardiovascular death or nonfatal myocardial infarction (the composite primary outcome) than a conservative strategy over a median follow-up of 4.1 years.

Retinoblastoma Outcomes Based on the 8th Edition American Joint Committee on Cancer Pathological Classification in 1411 Patients.

PURPOSE: To evaluate the outcomes of retinoblastoma (RB) based on the 8th edition of the American Joint Committee on Cancer (AJCC) pathological classification in a global cohort of patients. DESIGN: Retrospective, multicentre, intercontinental collaborative study PARTICIPANTS: 1411 patients INTERVENTION(S): Primary enucleation with/without adjuvant chemotherapy/radiotherapy MAIN OUTCOMES(S): Orbital tumor recurrence, tumor-related metastasis, tumor-related death RESULTS: Based on the 8th edition AJCC pathological classification, 645 (46%) eyes belonged to pT1, 164 (11%) to pT2, 493 (35%) to pT3, and 109 (8%) to pT4 categories. At a mean follow-up of 38 months (median, 35 months; <1-149 months), orbital tumor recurrence was seen in 8 (1%), 5 (3%), 22 (4%) and 25 (23%) of pT1, pT2, pT3, and pT4 (p<0.001) categories, respectively; tumor-related metastasis was seen in 7 (1%), 5 (3%), 40 (8%), and 46 (43%) of pT1, pT2, pT3, and pT4 (p<0.001) categories, respectively; tumor-related death was seen in 12 (2%), 7 (4%), 64 (13%), and 64 (59%) of pT1, pT2, pT3, and pT4 (p<0.001) categories, respectively. Multivariate Cox proportional hazards analysis of outcomes revealed pT category and adjuvant therapy as independent predictors of outcomes. Categories pT3b (p=0.005), pT3c (p<0.001), pT3d (p<0.001), and pT4 (p<0.001) had a greater hazard for orbital recurrence; categories pT2a (p=0.015), pT3a (p<0.001), pT3b (p<0.001), pT3c (p<0.001), pT3d (p<0.001) and pT4 (p<0.001) had a greater hazard for tumor-related metastasis; and categories pT2a (p=0.068), pT2b (p=0.004), pT3a (p<0.001), pT3b (p<0.001), pT3c (p<0.001), pT3d (p<0.001) and pT4 (p<0.001) had a greater hazard for tumor-related death when compared to the pT1 category. Patients who did not receive adjuvant therapy had greater hazards of orbital tumor recurrence in categories pT3b (p=0.005), pT3c (p=0.003), and pT4 (p=0.002); greater hazards of tumor-related metastasis in categories pT3a (p=0.001), pT3b (p=0.01), pT3c (p=0.001), and pT4 (p=0.007); and tumor-related death in categories pT3a (p<0.001), pT3b (p=0.009), pT3c (p=0.018), and pT4 (p<0.001) when compared to those who received adjuvant therapy. CONCLUSION: The 8th edition AJCC pathological classification predicts outcomes in patients undergoing primary enucleation for RB, and adjuvant therapy is associated with a lower risk of orbital recurrence, tumor-related metastasis, and tumor-related death in the pT3 and pT4 categories.

Improved Staging of Ciliary Body and Choroidal Melanomas Based on Estimation of Tumor Volume and Competing Risk Analyses.

PURPOSE: The current, 8th edition of the American Joint Committee on Cancer (AJCC) anatomic classification and staging model for uveal melanoma does not fully separate survival estimates for patients with advanced stages of the disease (e.g., IIIB and IIIC). Furthermore, some tumors in higher size categories have a smaller volume than tumors in lower categories. Therefore, we developed a novel model for prognostication of metastatic mortality based on estimations of tumor volume. DESIGN: Retrospective, multicenter case series of patients with uveal melanoma involving the choroid, ciliary body, or both. PARTICIPANTS: Six thousand five hundred twenty-eight consecutively registered patients treated at 3 tertiary ocular oncology centers on 2 continents between 1981 and 2022. METHODS: Data on survival, tumor size, and extent were collected for all 6528 patients. Tumor volume was estimated using a simple equation based on largest basal diameter and thickness. Volume-based size categories and stages were developed and validated in independent patient cohorts using competing risk analyses, and correlations with cytogenetic and cytomorphologic features were examined. MAIN OUTCOME MEASURE: Cumulative incidence of metastatic death. RESULTS: The 6528 patients were distributed over 7 stages based on estimated tumor volume and anatomic extent (V stages IA, IB, IIA, IIB, IIIA, IIIB, and IIIC), with a 15-year incidence of metastatic death ranging from 7% to 77%. A new category, V1min, and corresponding stage IA, were introduced, indicating an excellent prognosis. Metastatic mortality in V stage IIIC was significantly higher than that in V stage IIIB (P = 0.03), whereas incidence curves crossed for patients in AJCC stages IIIC vs. IIIB (P = 0.53). Univariable and multivariable competing risk regressions demonstrated higher Wald statistics for V stages compared with AJCC stages (1152 vs. 1038 and 71 vs. 17, respectively). The frequency of monosomy 3, gain of chromosome 8q, and epithelioid cytomorphologic features increased with tumor volume (R2 = 0.70, R2 = 0.50, and R2 = 0.71, respectively; P < 0.001) and showed similar correlations with both AJCC and V stages. CONCLUSIONS: Anatomic classification and staging of ciliary body and choroidal melanomas based on estimation of tumor volume improves prognostication of metastatic mortality.

Consensus Guidelines for Ocular Surveillance of von Hippel-Lindau Disease.

PURPOSE: To develop guidelines for ocular surveillance and early intervention for individuals with von Hippel-Lindau (VHL) disease. DESIGN: Systematic review of the literature. PARTICIPANTS: Expert panel of retina specialists and ocular oncologists. METHODS: A consortium of experts on clinical management of all-organ aspects of VHL disease was convened. Working groups with expertise in organ-specific features of VHL disease were tasked with development of evidence-based guidelines for each organ system. The ophthalmology subcommittee formulated questions for consideration and performed a systematic literature review. Evidence was graded for topic quality and relevance and the strength of each recommendation, and guideline recommendations were developed. RESULTS: The quality of evidence was limited, and no controlled clinical trial data were available. Consensus guidelines included: (1) individuals with known or suspected VHL disease should undergo periodic ocular screening (evidence type, III; evidence strength, C; degree of consensus, 2A); (2) patients at risk of VHL disease, including first-degree relatives of patients with known VHL disease, or any patient with single or multifocal retinal hemangioblastomas (RHs), should undergo genetic testing for pathologic VHL disease gene variants as part of an appropriate medical evaluation (III/C/2A); (3) ocular screening should begin within 12 months after birth and continue throughout life (III/C/2A); (4) ocular screening should occur approximately every 6 to 12 months until 30 years of age and then at least yearly thereafter (III/C-D/2A); (5) ocular screening should be performed before a planned pregnancy and every 6 to 12 months during pregnancy (IV/D/2A); (6) ultra-widefield color fundus photography may be helpful in certain circumstances to monitor RHs, and ultra-widefield fluorescein angiography may be helpful in certain circumstances to detect small RHs (IV/D/2A); (7) patients should be managed, whenever possible, by those with subspecialty training, with experience with VHL disease or RHs, or with both and ideally within the context of a multidisciplinary center capable of providing multiorgan surveillance and access to genetic testing (IV/D/2A); (8) extramacular or extrapapillary RHs should be treated promptly (III/C/2A). CONCLUSIONS: Based on available evidence from observational studies, broad agreement was reached for a strategy of lifelong surveillance and early treatment for ocular VHL disease. These guidelines were endorsed by the VHL Alliance and the International Society of Ocular Oncology and were approved by the American Academy of Ophthalmology Board of Trustees.

A multi-institutional feasibility study of intra-arterial chemotherapy in children with retinoblastoma. A Children's Oncology Group study (COG ARET12P1).

BACKGROUND: Intra-arterial chemotherapy (IA) as a treatment to salvage the eye with advanced retinoblastoma is increasingly utilized based on successes reported by institutions around the world mainly through retrospective studies. OBJECTIVE: To study the feasibility of delivering melphalan directly into the ophthalmic artery in a multi-institutional prospective study in children with newly diagnosed unilateral group D retinoblastoma. METHODS: The Children's Oncology Group (COG) initiated study ARET12P1 in 2014 and was open to nine institutions. Eligible patients older than six months of age were enrolled. The feasibility of delivering three injections of melphalan into the ophthalmic artery every 28 days was assessed. RESULTS: Nine institutions participated in this trial. Fourteen patients were enrolled, two of whom were unevaluable for feasibility. Four patients experienced a feasibility failure. In two patients, the ophthalmic artery could not be accessed for the second IA injection, in one the artery could not be accessed for the first injection, and one patient experienced grade 4 hypotension during the procedure. CONCLUSION: Delivery of prescribed therapy within the context of this study did not meet the feasibility goals of the study with only a 67% feasibility success rate. These results should caution centers that plan to initiate this treatment and suggest investment in training to achieve technical expertise or referral to centers with expertise.

High-Dose Intravitreal Topotecan for Recurrent Retinoblastoma, Subretinal Seeds, and Vitreous Seeds in 13 Consecutive Cases.

PURPOSE: To evaluate the efficacy and safety of high-dose intravitreal topotecan (IvitTopo) for recurrent retinoblastoma. METHODS: There were 13 patients with recurrent retinoblastoma treated with high-dose IvitTopo (90 micrograms (µg)/0.18cc-100 µg/0.20cc). The primary outcome measures were tumor control, globe salvage, and treatment complications. RESULTS: At date first seen (DFS), median patient age was 9 months, and the affected eye was classified as International Classification of Retinoblastoma (ICRB) Group B (n=2, 15%), Group C (n=3, 23%), or Group D (n=8, 62%) retinoblastoma with initial therapy of intravenous chemotherapy (n=9, 69%) or intra-arterial chemotherapy (n=4, 31%). Recurrent tumor was detected at median 10 months as solid tumor (n=3), subretinal seeds (n=10), and/or vitreous seeds (n=3) and high-dose IvitTopo (median 3 injections) delivered at monthly intervals. Additional chemotherapy was delivered by intra-arterial (n=8, 62%) or intravenous (n=1, 8%) routes, and 1 eye received additional cryotherapy (n=1, 8%). In 3 cases (23%) there was no additional therapy. At mean follow-up of 9 months, regression of solid tumor, subretinal seeds and vitreous seeds was achieved in 12 cases (92%), and globe salvage was achieved in all cases (n=13, 100%). Of those 3 eyes treated with high-dose IvitTopo alone, tumor control was initially achieved in all cases (100%), but one case that previously demonstrated massive vitreous seeding showed late recurrence of a solitary vitreous seed at 8 months. There were no complications. CONCLUSIONS: High-dose IvitTopo is an effective and safe therapy for recurrent retinoblastoma, in conjunction with other therapy, and possibly as a stand-alone therapy.

High-Risk Histopathological Features of Retinoblastoma following Primary Enucleation: A Global Study of 1426 Patients from 5 Continents.

PURPOSE: To evaluate high-risk histopathological features (HRHF) following primary enucleation of eyes with retinoblastoma (RB) and assess the patient outcomes across continents. METHODS: Retrospective study of 1426 primarily enucleated RB eyes from five continents. RESULTS: Of all, 923 (65%) were from Asia (AS), 27 (2%) from Australia (AUS), 120 (8%) from Europe (EUR), 162 (11%) from North America (NA), and 194 (14%) from South America (SA). Based on the continent (AS vs. AUS vs. EUR vs. NA vs. SA), the histopathology features included massive choroidal invasion (31% vs. 7% vs. 13% vs. 19% vs. 27%, p=0.001), post-laminar optic nerve invasion (27% vs. 0% vs. 16% vs. 21% vs. 19%, p=0.0006), scleral infiltration (5% vs. 0% vs. 4% vs. 2% vs. 7%, p=0.13), and microscopic extrascleral infiltration (4% vs. 0% vs. <1% vs. <1% vs. 4%, p=0.68). Adjuvant chemotherapy with/without orbital radiotherapy was given in 761 (53%) patients. Based on Kaplan-Meier estimates in different continents (AS vs. AUS vs. EUR vs. NA vs. SA), the 6-year risk of orbital tumor recurrence was 5% vs. 2% vs. 0% vs. 0% vs. 12% (p<0.001), systemic metastasis was reported in 8% vs. 5% vs. 2% vs. 0% vs. 13% (p=0.001), and death in 10% vs. 3% vs. 2% vs. 0% vs. 11% (p<0.001) patients. CONCLUSION: There is a wide variation in the infiltrative histopathology features of RB across continents, resulting in variable outcomes. SA and AS had a higher risk of orbital tumor recurrence, systemic metastasis, and death compared to AUS, EUR, and NA.

Strabismus management in retinoblastoma survivors.

PURPOSE: To report the result of strabismus surgery in eye-salvaged retinoblastoma (Rb) patients. METHODS: A retrospective case series including 18 patients with Rb and strabismus who underwent strabismus surgery after completing tumor treatment by a single pediatric ophthalmologist. RESULTS: A total of 18 patients (10 females and 8 males) were included with a mean age of 13.3 ± 3.0 (range, 2-39) months at the time tumor presentation and 6.0 ± 1.5 (range, 4-9) years at the time of strabismus surgery. Ten (56%) patients had unilateral and 8(44%) had bilateral involvement and the most common worse eye tumor's group was D (n = 11), C (n = 4), B (n = 2) and E (n = 1). Macula was involved by the tumors in 12 (67%) patients. The tumors were managed by intravenous chemotherapy (n = 8, 47%), intra-arterial chemotherapy (n = 7, 41%) and both (n = 3, 17%). After complete treatment, the average time to strabismus surgery was 29.9 ± 20.5 (range, 12-84) months. Except for one, visual acuity was equal or less than 1.0 logMAR (≤ 20/200) in the affected eye. Seven (39%) patients had exotropia, 11(61%) had esotropia (P = 0.346) and vertical deviation was found in 8 (48%) cases. The angle of deviation was 42.0 ± 10.4 (range, 30-60) prism diopter (PD) for esotropic and 35.7 ± 7.9 (range, 25-50) PD for exotropic patients (P = 0.32) that after surgery significantly decreased to 8.5 ± 5.3 PD in esotropic cases and 5.9 ± 6.7 PD in exotropic cases (P < 0.001). The mean follow-up after surgery was 15.2 ± 2.0 (range, 10-24) months, in which, 3 (17%) patients needed a second surgery. CONCLUSION: Strabismus surgery in treated Rb is safe and results of the surgeries are acceptable and close to the general population. There was not associated with tumor recurrence or metastasis.

Metastasis-free survival of uveal melanoma by tumour size category based on The Cancer Genome Atlas (TCGA) classification in 1001 cases.

BACKGROUND: Uveal melanoma (UM) can be classified by tumour size category and by The Cancer Genome Atlas (TCGA) groups (cytogenetic-based, 4-category prognostic classification into Groups A-D). This study was conducted to assess impact on metastasis-free survival (MFS) in UM by tumour size category based on correlation with TCGA classification. METHODS: Retrospective analysis of 1001 cases categorised as small (0.0-3.0 mm), medium (3.1-8.0 mm) and large (≥8.1 mm), grouped by TCGA classification. RESULTS: Of 1001 cases, TCGA Groups (A/B/C/D) included small (n = 270, 75%/11%/13%/1%), medium (n = 503, 46%/14%/27%/13%) and large (n = 228, 23%/19%/38%/20%) UM. The 5-and 10-year Kaplan-Meier MFS for small UM revealed Group A (98%, 98%), Group B (100%, 100%), Group C (86%, NA) and Group D (100%, NA). For medium UM, the values dropped with Group A (95%, 93%), Group B (90%, 90%), Group C (68%, 38%), and Group D (44%, NA). For large UM, the values dropped further with Group A (94%, 86%), Group B (85%, NA), Group C (40%, 28%), and Group D (23%, NA). Additionally, a comparison (small vs. medium vs. large tumour size category) revealed TCGA low-risk grouping (Groups A or B) in 86% vs. 60% vs. 58% cases with UM. CONCLUSION: By tumour size category, favourable cytogenetics (Groups A or B) is found in 86% of small tumours, 60% of medium tumours, and 58% of large tumours. The MFS at 10 years for favourable cytogenetics was 98% for small tumours, 92% for medium tumours, and 54% for large tumours. Tumour size category can serve as a surrogate for TCGA.

Pleomorphic Sarcoma, an Atypical Conjunctival Tumor.

Sarcomas are malignant tumors of connective tissue with a mesodermal origin that, in rare occasions, is presented in conjunctiva; undifferentiated pleomorphic sarcoma represents <1% of orbital tumors. It is characterized by not meeting the histologic, immunohistochemical, ultrastructural, or molecular criteria in the classification proposed by the World Health Organization. The authors present the case of an 82-year-old man, blind due to absolute glaucoma, who consulted for a conjunctival mass of a few months' evolution. He reported progressive enlargement of the left eye, associated with red eye, conjunctival discharge, and foreign body sensation. The patient was examined by the anterior segment department, which decided to biopsy the lesion due to the biomicroscopic aspect. After the diagnosis of a pleomorphic sarcoma by histopathology and immunohistochemistry, enucleation of the eye was decided.

Intrinsic disorder in PRAME and its role in uveal melanoma.

INTRODUCTION: The PReferentially expressed Antigen in MElanoma (PRAME) protein has been shown to be an independent biomarker for increased risk of metastasis in Class 1 uveal melanomas (UM). Intrinsically disordered proteins and regions of proteins (IDPs/IDPRs) are proteins that do not have a well-defined three-dimensional structure and have been linked to neoplastic development. Our study aimed to evaluate the presence of intrinsic disorder in PRAME and the role these structureless regions have in PRAME( +) Class 1 UM. METHODS: A bioinformatics study to characterize PRAME's propensity for the intrinsic disorder. We first used the AlphaFold tool to qualitatively assess the protein structure of PRAME. Then we used the Compositional Profiler and a set of per-residue intrinsic disorder predictors to quantify the intrinsic disorder. The Database of Disordered Protein Prediction (D2P2) platform, IUPred, FuzDrop, fIDPnn, AUCpred, SPOT-Disorder2, and metapredict V2 allowed us to evaluate the potential functional disorder of PRAME. Additionally, we used the Search Tool for the Retrieval of Interacting Genes (STRING) to analyze PRAME's potential interactions with other proteins. RESULTS: Our structural analysis showed that PRAME contains intrinsically disordered protein regions (IDPRs), which are structureless and flexible. We found that PRAME is significantly enriched with serine (p-value < 0.05), a disorder-promoting amino acid. PRAME was found to have an average disorder score of 16.49% (i.e., moderately disordered) across six per-residue intrinsic disorder predictors. Our IUPred analysis revealed the presence of disorder-to-order transition (DOT) regions in PRAME near the C-terminus of the protein (residues 475-509). The D2P2 platform predicted a region from approximately 140 and 175 to be highly concentrated with post-translational modifications (PTMs). FuzDrop predicted the PTM hot spot of PRAME to be a droplet-promoting region and an aggregation hotspot. Finally, our analysis using the STRING tool revealed that PRAME has significantly more interactions with other proteins than expected for randomly selected proteins of the same size, with the ability to interact with 84 different partners (STRING analysis result: p-value < 1.0 × 10-16; model confidence: 0.400). CONCLUSION: Our study revealed that PRAME has IDPRs that are possibly linked to its functionality in the context of Class 1 UM. The regions of functionality (i.e., DOT regions, PTM sites, droplet-promoting regions, and aggregation hotspots) are localized to regions of high levels of disorder. PRAME has a complex protein-protein interaction (PPI) network that may be secondary to the structureless features of the polypeptide. Our findings contribute to our understanding of UM and suggest that IDPRs and DOT regions in PRAME may be targeted in developing new therapies for this aggressive cancer. Video Abstract.

Addition of intravitreal carboplatin with melphalan for management of vitreous seeding in retinoblastoma.

PURPOSE: To evaluate the efficacy and toxicity of intravitreal carboplatin plus melphalan for the treatment of vitreous seeds in eyes with retinoblastoma (RB). METHODS: This retrospective series at a tertiary referral center included 22 consecutive RB patients who had received intravitreal carboplatin (16 µg per 0.05 ml) combined with melphalan (30 µg in 0.03 ml) [IVi (Ca-Me)] for treatment of vitreous seeds. Tumor control and drug toxicities were recorded. RESULTS: There were 22 eyes of 22 patients, divided into primary group (n = 13) without history of previous intravitreal chemotherapy (IViC) and refractory group (n = 9) with history of previous IViC using melphalan and/or topotecan. The demographics and clinical findings of the primary and refractory groups did not differ significantly. The 6-month follow-up revealed complete vitreous seed control (77% vs. 89%, p = 0.47). Vitreous seed recurrence was detected in 1 eye of each group at 6 months. During the next 18-month follow-up period, no recurrence of seed was observed. The response to IVi (Ca-Me) was not significantly influenced by previous IViC (p = 0.70), primary systemic or intra-arterial chemotherapy (p = 0.45), or the type of regression (p = 0.35). The most common tumor treatment complications were retinal detachment (RD) (n = 2), early hypotony (n = 2) and late hypotony (n = 4, unrelated), cataract (n = 2), and severe pigment dispersion (n = 1). Enucleation was performed in 8 eyes, for total RD (n = 1), phthisis bulbi (n = 5), and extensive solid tumor recurrence (n = 2). There was no case of orbital invasion, systemic metastasis, or death. CONCLUSION: Based on this interventional case series for primary and refractory vitreous RB seeds, carboplatin plus melphalan therapy may be effective with few toxic side effects.

SARCOID GRANULOMA OF THE CHOROID AND CILIARY BODY IN 50 CASES.

PURPOSE: To describe the clinical and imaging features of sarcoid granuloma of the choroid and ciliary body. METHODS: Retrospective case series of patients with choroid and/or ciliary body sarcoid granuloma managed at the Ocular Oncology Service at Wills Eye Hospital. RESULTS: The mean patient age at diagnosis was 51.0 years (54.1, 11.0-83.8 years). The mean logMAR visual acuity at presentation was 0.3 (0.2, 0.0-3.0) [Snellen equivalent 20/40 (20/30, HM-20/20)]. Clinical features included mean basal dimension of 5.2 mm (4.0, 0.3-20.0 mm) and thickness of 1.7 mm (1.8, 0.0-3.6 mm), yellow color (41, 82%), multifocality (18, 36%), and irregular vermiform margins (46, 92%). Related clinical features included inflammation of the anterior chamber (1, 2%), vitreous (5, 10%), and retina (5, 10%). Imaging features by optical coherence tomography of the choroid lesions (n = 49) demonstrated clear subretinal fluid (6, 12%), "dirty" subretinal fluid (14, 28%), cystoid macular edema (1, 2%), overlying retinal edema (6, 12%), and localized vitreous cellularity (1, 2%). Management included sub-Tenon's triamcinolone (11, 22%), intravitreal triamcinolone (3, 6%), systemic corticosteroids (19, 38%), or observation (26, 52%). Systemic sarcoidosis was present before ocular diagnosis (13, 26%), detected during ophthalmic care (4, 8%), detected after ocular diagnosis (3, 6%), or not found (30, 60%) over a mean follow-up of 13.7 months (6.9, 0.0-138.2). CONCLUSION: Sarcoid granuloma of the choroid and/or ciliary body can manifest without anterior segment or vitreous/retina inflammation in many cases and reveal underlying systemic sarcoidosis in 40% of cases. A distinguishing feature of choroidal sarcoid granuloma was its vermiform margin.

Truxima (rituximab-abbs) for Periocular Xanthogranuloma with Adult-Onset Asthma and Systemic IgG4-Related Disease.

A 58-year-old female with a 3-year history of adult-onset asthma, bilateral blepharoptosis, dry eye, and yellow-orange xanthelasma-like plaques extensively involving both upper eyelids presented with a diagnosis of adult-onset asthma with periocular xanthogranuloma (AAPOX) and systemic IgG4-related disease. Over the next 8 years, she received 10 intralesional triamcinolone injections (40-80 mg) in the right upper eyelid, 7 intralesional triamcinolone injections (30-60 mg) in the left upper eyelid, underwent right anterior orbitotomy twice followed by 4 doses of rituximab (1000 mg intravenous infusion) without regression of the AAPOX. The patient was then treated with 2 monthly doses of Truxima (1000 mg intravenous infusion), a biosimilar to rituximab. At the most recent follow-up, 13 months later, the xanthelasma-like plaques and orbital infiltration had markedly improved. To the best of the authors' knowledge, this is the first report of Truxima being used to treat AAPOX with systemic IgG4-related disease and to generate a sustained clinical response.

Conjunctival Melanoma in 430 Cases: Comparative Analysis of the Impact of Orbital Invasion on Tumor Recurrence, Metastasis, and Death.

PURPOSE: To compare the clinical features at presentation and treatment outcomes of conjunctival melanoma by absence/presence of orbital invasion. METHODS: A retrospective review of patients with conjunctival melanoma managed at a single tertiary referral center from April 18, 1974, to September 9, 2019. RESULTS: Of 430 patients with conjunctival melanoma, 21 (5%) had orbital invasion at presentation. A comparison between the 2 groups (orbital invasion absent vs. present) revealed that the orbital invasion group had a higher frequency of prior eyelid incisional biopsy (5% vs. 24%, P = 0.006), greater tumor basal diameter (12.2 vs. 17.3, P = 0.009), greater tumor thickness (2.4 vs. 7.0, P < 0.001), more quadrants involved (1.8 vs. 2.5, P = 0.002), and more clock hours involved (4.4 vs. 5.8, P = 0.037). In addition, those with orbital invasion were more likely to undergo exenteration as primary treatment (1% vs. 24%, P < 0.001). Multivariate relative risk regression analysis revealed that variables predictive of orbital invasion included greater tumor thickness (P < 0.001) and greater involvement of the fornix (P = 0.031) and tarsus (P = 0.033). Outcomes revealed orbital invasion group with greater 5-year/10-year distant metastatic rate (16%/21% vs. 63%/63%, P = 0.005), and greater melanoma-related death rate (7%/13% vs. 38%/53%, P = 0.001). CONCLUSIONS: Conjunctival melanoma with orbital invasion at presentation demonstrate larger, more extensive tumors involving the fornix or tarsus, and with greater rate of melanoma-related metastasis and death.

Exogenous Ochronosis With Ocular Involvement From Chronic Use of Teavigo.

Exogenous ochronosis refers to accumulation of homogentisic acid metabolites in tissues, manifesting as pigmentation of affected tissues. Phenolic compounds are most commonly implicated, including hydroquinone, quinine, phenol, resorcinol, mercury, and picric acid. The affected connective tissues exhibit brownish discoloration when heavily pigmented and the histopathological appearance is characteristic with "banana-shaped" ochre-colored pigment deposits. Herein, the authors describe a rare case of exogenous ochronosis involving the conjunctiva, sclera and skin, as a result of chronic use of Teavigo (94% epigallocatechin gallate), a polyphenol compound with postulated antioxidant and antiapoptotic activity.

Bilateral Conjunctival Actinic Granuloma With Necrobiotic Vasculitic Pattern: A Diagnosis of Exclusion.

A 53-year-old Caucasian male presented with an inflamed-appearing limbal nodule in his OD, clinically compatible with nodular episcleritis, that was unresponsive to topical corticosteroid therapy. Excisional biopsy of the lesion was performed and histopathological examination revealed foci of necrotizing vasculitis and granulomatous inflammation in a background of intense actinic elastosis. Infectious stains for organisms were negative. A comprehensive systemic evaluation for vasculitides was negative. Three years later, the patient returned with a clinically and histopathologically identical lesion in his OS. Systemic evaluation was noncontributory again, and a diagnosis of bilateral conjunctival actinic granuloma with necrobiotic vasculitic pattern was made.

Adding the Cancer Genome Atlas Chromosome Classes to American Joint Committee on Cancer System Offers More Precise Prognostication in Uveal Melanoma.

PURPOSE: Uveal melanoma (UM) is a rare disease and the most common primary intraocular malignancy in adults, with a high risk of metastases. Reliable prognostication systems are based on anatomic features, as in the tumor-node-metastasis staging of the American Joint Committee on Cancer (AJCC) system, or on genetic information, as in The Cancer Genome Atlas (TCGA) system. Prior evidence suggests that combining both systems may be beneficial. We evaluated the benefit of combining the TCGA and AJCC systems in a large cohort of patients. DESIGN: Retrospective case series of patients with UM. PARTICIPANTS: Nine hundred seventy-nine patients with a choroidal or ciliary body melanoma treated at the Wills Eye Hospital between 1998 and 2020, 94% of whom received eye-sparing treatment. METHODS: Tumors were classified into 4 TCGA groups based on chromosome copy number: A (disomy 3, normal 8q), B (disomy 3, any 8q gain), C (monosomy 3, 1 extra copy of 8q), and D (monosomy 3, multiple 8q gain). The eighth edition of the AJCC staging manual was used for AJCC staging. Cox regression and the log-rank test were used for survival analysis. MAIN OUTCOME MEASURE: Metastasis-free survival. RESULTS: Combining information of the 2 systems improved prognostication in intermediate groups: in TCGA group C, we saw an increased rate of metastasis in AJCC stage III (28%) compared with stage II (8.9%); the same was seen in AJCC stage II, going from TCGA group C (8.9%) to group D (46%), and in AJCC stage III, going from group C (28%) to group D (49%). In patients with AJCC stage II or III disease, loss of chromosome 3 and gain of 8q (TCGA groups C and D) significantly worsened the prognosis, with multiple 8q gain (TCGA group D) having a greater impact. CONCLUSIONS: Combining information from AJCC stages and TCGA groups yields a better predictive power even in this set of relatively small tumors. We propose that physicians take both systems into account whenever possible, especially in moderate-risk groups.

Iris and Ciliary Body Melanocytomas Are Defined by Solitary GNAQ Mutation Without Additional Oncogenic Alterations.

OBJECTIVE: To analyze the genetic features of melanocytomas and melanomas of the anterior uvea and assess the value of molecular testing for diagnosis and prognostication. DESIGN: Retrospective case-control study. SUBJECTS: Patients with melanocytoma (n = 16) and melanoma (n = 19) of the anterior uvea. METHODS: Targeted next-generation sequencing was performed on formalin-fixed, paraffin-embedded tumor tissue from anterior uveal melanocytic tumors and correlated with clinicopathologic features. MAIN OUTCOME MEASURES: Presence or absence of accompanying oncogenic alterations beyond GNAQ/GNA11 and their association with histologic features and local recurrence. RESULTS: Hotspot missense mutations in GNAQ/GNA11 were identified in 91% (32/35) of all cases. None of the melanocytomas with or without atypia demonstrated chromosomal imbalances or additional oncogenic variants beyond GNAQ mutation, and none recurred over a median follow-up of 36 months. Additional alterations identified in a subset of melanomas include mutations in BAP1 (n = 3), EIF1AX (n = 4), SRSF2 (n = 1), PTEN (n = 1), and EP300 (n = 1); monosomy 3p (n = 6); trisomy 6p (n = 3); trisomy 8q (n = 2); and an ultraviolet mutational signature (n = 5). Local recurrences were limited to melanomas, all of which demonstrated oncogenic alterations in addition to GNAQ/GNA11 (n = 5). A single melanoma harboring GNAQ and BAP1 mutations and monosomy 3 was the only tumor that metastasized. CONCLUSIONS: In this study, anterior segment uveal melanocytomas did not display oncogenic alterations beyond GNAQ/GNA11. Therefore, they are genetically similar to uveal nevi rather than uveal melanoma based on their molecular features known from the literature. Molecular testing can be performed on borderline cases to aid risk stratification and clinical management decisions.

Mutational Landscape and Outcomes of Conjunctival Melanoma in 101 Patients.

PURPOSE: To evaluate targetable mutations and molecular genetic pathways in conjunctival melanoma with clinical correlation. DESIGN: Observational case series. PARTICIPANTS: Patients with conjunctival melanoma. MAIN OUTCOME MEASURES: Mutational profile of the tumor by next-generation sequencing (NGS), alternative lengthening of telomeres (ALT) by fluorescence in situ hybridization (FISH), and ATRX immunohistochemistry. Outcomes at 2 years and 5 years of tumor-related metastasis and death were recorded. RESULTS: Of the 101 patients, mean age at presentation was 60 years, 52% were male, and 88% were White. The NGS panels initially targeted BRAF only (n = 6, 6%), BRAF/NRAS (n = 17, 17%), and BRAF/NRAS/NF1 (n = 10, 10%). Sixty-eight tumors were tested with the expanded 592-gene panel. Next-generation sequencing identified high-frequency mutations in NF1 (29/74, 39%), BRAF (31/101, 31%), NRAS (25/95, 26%), and ATRX (17/68, 25%). Of those with an ATRX mutation, 12 (71%) had an additional NF1 mutation. A subset analysis of 21 melanomas showed that the ATRX mutation was associated with loss of ATRX protein expression and ALT. Loss of ATRX expression and ALT were present in both intraepithelial and invasive tumors, suggesting that an ATRX mutation is an early event in conjunctival melanoma progression. The NF1 and ATRX mutations were associated with tarsal (vs. nontarsal) tumors (NF1: 28% vs. 9%, P = 0.035, ATRX: 41% vs. 14%, P = 0.021) and orbital (vs. nonorbital) tumors (ATRX: 24% vs. 2%, P = 0.007). ATRXMUT (vs. ATRXWT) tumors were associated with a lower 2-year rate of metastasis (0% vs. 24%, P = 0.005). NRASMUT (vs. NRASWT) tumors were associated with a greater 2-year rate of metastasis (28% vs. 14%, P = 0.07) and death (16% vs. 4%, P = 0.04), with a 5-fold increased risk of death (relative risk, 5.45 [95% confidence interval, 1.11-26.71], P = 0.039). CONCLUSIONS: This study confirms the high frequency of previously documented BRAF and NRAS mutations and recently reported ATRX and NF1 mutations in conjunctival melanoma. An NRAS mutation implied increased risk for metastasis and death. Loss of ATRX and ALT may be early events in conjunctival melanoma development.
