Determinants of overall survival in patients with metastatic uveal melanoma.

BACKGROUND: Despite improvements in the treatment of primary uveal melanoma (UM), patients with metastatic disease continue to exhibit poor survival. METHODS: A retrospective review of metastatic UM patients at Yale (initial cohort) and Memorial Sloan Kettering (validation cohort) was conducted. Cox proportional hazards regression was used to determine baseline factors that are associated with overall survival, including sex, Eastern Cooperative Oncology Group (ECOG) Performance Status Scale, laboratory measurements, metastasis location, and use of anti-CTLA-4 and anti-PD-1 therapies. Differences in overall survival were analyzed using Kaplan-Meier analysis. RESULTS: A total of 89 patients with metastatic UM were identified; 71 and 18, in the initial and validation cohorts, respectively. In the initial cohort, median follow-up was 19.8 months (range, 2-127 months) and median overall survival was 21.8 months (95% CI, 16.6-31.3). Female sex, anti-CTLA-4, and anti-PD-1 therapy were associated with better survival outcomes with adjusted death hazard ratios (HRs) of 0.40 (95% CI, 0.20-0.78), 0.44 (0.20-0.97), and 0.42 (0.22-0.84), respectively, whereas development of hepatic metastases and ECOG score ≥1 (per 1 U/L) were associated with worse survival outcomes with HRs of 2.86 (1.28-7.13) and 2.84 (1.29-6.09), respectively. In both the initial and validation cohorts, use of immune checkpoint inhibitors was associated with improved overall survival after adjusting for sex and ECOG score, with death HRs of 0.22 (0.08-0.56) and 0.04 (0.002-0.26), respectively. CONCLUSIONS: Development of extrahepatic-only metastases, ECOG of 0, immune checkpoint therapy, and female sex were each associated with more than 2-fold reductions in risk of death. PLAIN LANGUAGE SUMMARY: Metastatic uveal melanoma patients face limited treatment options and poor survival rates. Results from this retrospective analysis indicate that immune checkpoint inhibitors, such as anti-CTLA-4 and anti-PD-1 therapies, were associated with improved survival outcomes. Factors such as extrahepatic-only metastases, better baseline performance status, and female sex contributed to a more than 2-fold reduction in death risk. These findings highlight the potential of immunotherapy in treating metastatic uveal melanoma.

Validation of the Prognostic Usefulness of the Gene Expression Profiling Test in Patients with Uveal Melanoma.

PURPOSE: To validate the prognostic usefulness of gene expression profile (GEP) testing in patients with uveal melanoma. To determine whether combining tumor size with the GEP classification provides additional prognostic value. DESIGN: Retrospective analysis. PARTICIPANTS: Patients with a diagnosis of choroidal melanoma examined at Yale New Haven Hospital; University of California, San Diego; and Memorial Sloan Kettering Cancer Center. METHODS: Patients' demographic and clinical data and tumor characteristics were collected. Univariate and multivariate Cox hazard regression analysis were used to assess the association between tumor characteristics and GEP classification with metastasis as an outcome. MAIN OUTCOME MEASURES: Metastasis-free survival (MFS). RESULTS: Of the 337 individuals included in the study, 87 demonstrated metastases. The mean follow-up time was 37.2 (standard deviation [SD], 40.2) months for patients with metastases and 55.0 (SD, 49.3) months for those without metastases. Tumors of larger thickness and GEP class 2 (vs. class 1) were associated significantly with increased risk of metastasis. Tumor thickness showed better prognostic usefulness than GEP classification (Wald statistic, 40.7 and 24.2, respectively). Class 2 tumors with a thickness of 7.0 mm or more were associated with increased risk of metastasis than tumors with a thickness of < 7.0 mm (hazard ratio [HR], 3.23; 95% confidence interval [CI], 1.61-6.51), whereas class 1 tumors with a thickness of 9.0 mm or more were associated with increased risk of metastasis than tumors with a thickness of < 9.0 mm (HR, 2.07; 95% CI, 0.86-4.99). No difference in MFS was found between patients with class 1A tumors compared with those with class 1B tumors (P = 0.8). Patients with class 2 tumors showed an observed 5-year MFS of 47.5% (95% CI, 36.0%-62.8%). CONCLUSIONS: Tumor size was the most significant predictor of metastasis and provided additional prognostic value independent of GEP classification. In addition, rates of metastasis for class 2 tumors were lower than estimates reported by Castle Bioscience, and no difference in rates of metastasis were found between class 1A and 1B tumors. This indicates that tumor size should be accounted for when relying on GEP for prognostication and that patients with GEP class 1A or 1B tumors may benefit from the same metastatic surveillance protocols.

NK/T-cell Lymphoma With Orbital Involvement: A Case Report and Systematic Review of the Literature.

PURPOSE: To present the clinical course of a patient with recurrent NK/T-cell lymphoma (NKTL) involving the orbit and to review the literature on patients with NKTL involving the orbit. METHODS: The PubMed database was searched for all cases of NKTL involving orbital, intraocular, or adnexal ocular structures. RESULTS: Ninety-six patients were included in the final analysis. The mean age of diagnosis was 48.1 ± 16.8 years. The patients were 53/96 (55.2%) male and 43/96 (44.8%) female. Tumor location varied and included the orbit in 80/96 (83.3%), nasosinus in 56/96 (58.3%), uvea in 11/96 (11.5%), lacrimal gland in 9/96 (9.4%), lacrimal drainage system in 11/96 (11.5%), and conjunctiva in 7/96 (7.3%) cases. Management included surgical debulking in 29/96 (30.2%) cases, radiotherapy in 52/96 (54.2%) cases, and chemotherapy in 82/96 (85.4%) cases. Median survival was 6 months (95% CI: 5-9). Chemotherapy (hazard ratio = 0.80, 95% CI: 0.67-0.95, p = 0.013), radiotherapy (hazard ratio = 0.75, 95% CI: 0.64-0.87, p < 0.001), and orbital involvement being a recurrence of disease (hazard ratio = 0.79, 95% CI: 0.67-0.95, p = 0.009) were associated with improved survival. Advanced Ann Arbor stage (III-IV) at diagnosis (hazard ratio = 1.22, 95% CI: 1.08-1.38, p = 0.001), vision loss (hazard ratio = 1.18, 95% CI: 1.04-1.34, p = 0.009), proptosis (hazard ratio = 1.15, 95% CI: 1.01-1.30, p = 0.035) and periorbital swelling (hazard ratio = 1.15, 95% CI: 1.00-1.33, p = 0.048) were associated with poor survival. CONCLUSIONS: NK/T-cell lymphoma involving the orbit, globe, or ocular adnexa heralds a poor prognosis where early diagnosis and therapy are critical. The use of radiotherapy and chemotherapy is associated with improved survival.

Dacryocystitis in a patient with Samter's triad.

Samter's triad, also known as aspirin-exacerbated respiratory disease, is characterized by nasal polyposis, bronchial asthma, and aspirin intolerance. Here, we present a case of a 36-year-old woman with a history of Samter's triad and recurrent dacryocystitis. After combined dacryocystorhinostomy and endoscopic sinus surgery, pathological specimens of the lacrimal sac showed respiratory fibrosis with chronic inflammation and eosinophilic infiltration. Our case demonstrates that Samter's triad is a potential etiology for inflammatory nasolacrimal duct obstruction.

Local recurrence of uveal melanoma and concomitant brain metastases associated with an activating telomerase promoter mutation seven years after secondary enucleation.

Purpose: To describe a case of local recurrence of uveal melanoma with concomitant brain metastases after secondary enucleation. Observations: A 73 year-old patient presented with dizziness and gait instability. MRI of the orbits and brain showed an anophthalmic socket with an orbital implant and an associated optic nerve mass as well as multiple mass lesions in the brain. The patient's history was significant for secondary enucleation for uveal melanoma recurrence seven years prior to presentation. Histopathology of the enucleated eye revealed no signs of extrascleral extension or optic nerve invasion. Biopsy of the optic nerve mass confirmed recurrent uveal melanoma with somatic mutations in GNAQ (Q209L) and the telomerase (TERT) promoter (c.1-124C > T) found on targeted next-generation sequencing (NGS). The same mutations were found in the primary tumor in the patient's archived enucleation samples. Conclusions: Local recurrence of uveal melanoma can occur after enucleation and is associated with an increased risk of systemic metastases. It is important for clinicians to monitor patients for local recurrence and systemic metastases even after enucleation. Genetic biomarkers may play an important role in identifying tumors at highest risk of local recurrence and metastasis. To our knowledge, this is the first case study to describe the TERT promoter mutation c.1-124C > T in the setting of recurrent uveal melanoma.

Cemiplimab for Orbital Squamous Cell Carcinoma in 11 Cases.

PURPOSE: To review the demographics, clinical features, and response of orbital squamous cell carcinoma treated with cemiplimab. METHODS: This is a retrospective multi-institutional series. Patient characteristics, drug dosing, duration, and response to treatment were evaluated. RESULTS: The study cohort consisted of 11 patients from 5 institutions. All patients received a regimen of 350 mg q 3 weeks and an average of 11.2 cycles (SD 5.8). No patient experienced significant side effects requiring treatment or cessation of cemiplimab. Complete response was achieved in 9 patients (82%) treated with cemiplimab. CONCLUSIONS: Immune checkpoint inhibitors, such as cemiplimab provide a globe-sparing option for the treatment of orbital squamous cell carcinoma. It is important to consider these agents especially when orbital exenteration is the alternative.

Necrotic Uveal Melanoma Mimics Orbital Cellulitis: A Review.

Background: Uveal melanoma is the most common primary intraocular malignancy in adults, often resulting in painless vision loss. We report a case of necrotic uveal melanoma presenting with orbital inflammation mimicking orbital cellulitis and present a comprehensive review of the literature and tabulation of reported cases. Summary: Our review found 44 published reports of spontaneously necrotic uveal melanoma involving 55 patients. Of these reports, 26 patients (47%) presented with orbital cellulitis. Presenting symptoms of necrotic uveal melanoma with orbital cellulitis included proptosis (82.8%), pain (80.7%), vision loss (61.5%), and restricted extraocular movements (46.2%). Key Messages: Uveal melanoma can rarely mimic orbital cellulitis. Autoinfarction and tumor necrosis causes secondary orbital inflammation. Intraocular malignancy must remain in the differential for patients with orbital inflammation and vision loss.

Autoimmune retinopathy with associated anti-retinal antibodies as a potential immune-related adverse event associated with immunotherapy in patients with advanced cutaneous melanoma: case series and systematic review.

OBJECTIVE: To demonstrate the spectrum of autoimmune retinopathy (AIR) associated with immunotherapy for advanced cutaneous melanoma. METHODS AND ANALYSIS: Retrospective chart review on patients with advanced cutaneous melanoma who developed AIR after initiating immunotherapy. Complete ophthalmic examination and relevant ancillary testing were performed on each patient. The presence of AIR-associated anti-retinal antibodies was confirmed by western blot and/or immunohistochemical staining. Ophthalmic and systemic outcomes after treatment for AIR were followed over time. A systematic review of AIR associated with immunotherapy for cutaneous or non-ocular mucosal melanoma was carried out in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Case 1 developed photopsia and nyctalopia with electroretinographic findings characteristic for melanoma-associated retinopathy 1 week after initiating ipilimumab/nivolumab immunotherapy. Case 2 experienced new severe bilateral visual field loss associated with anti-retinal and anti-optic nerve antibodies while on maintenance nivolumab immunotherapy. Case 3 developed decreased visual acuity due to acute exudative polymorphous vitelliform maculopathy within 2 weeks of initiating ipilimumab/nivolumab immunotherapy. All patients had concurrent extraocular immune-related adverse events in addition to the presence of anti-retinal antibodies on serological testing. 14 published cases of AIR associated with immunotherapy for cutaneous or non-ocular mucosal melanoma were identified and reviewed. CONCLUSIONS: Immune checkpoint inhibition can trigger the development of AIR with varied clinical manifestations in patients with advanced cutaneous melanoma. This study highlights the need for close monitoring in cutaneous melanoma patients receiving immunotherapy who develop new visual symptoms with or without funduscopic changes, as well as the potential role for screening of patients prior to initiating immunotherapy.

Ocular Neisseria gonorrhea in a patient on immune checkpoint inhibitors.

Although immune checkpoint inhibitors have revolutionized the treatment of cancers, their role in the pathogenesis of chronic infections remains unclear. Here, we present the case of a patient on a cocktail of checkpoint inhibitors who presented with severe bilateral gonococcal conjunctivitis, orbital cellulitis and vitritis, without a history of genital infection.

Metastatic Choroidal Melanoma Presenting as Neovascular Glaucoma.

Uveal melanoma is the most common primary intraocular tumor in adults and can have varying presentations, although it is frequently asymptomatic. One rare presentation of uveal melanoma is neovascular glaucoma (NVG). We present a case of a 20-year-old male who presented with 2 weeks of left eye redness and decreased vision who was found to have NVG. He was referred for evaluation of glaucoma. Fundoscopic and ultrasonographic examination revealed a mushroom-shaped choroidal mass with low internal reflectivity consistent with choroidal melanoma. The patient underwent enucleation, and metastatic workup revealed hepatic metastases. The patient died 18 months after initial diagnosis. This case emphasizes the importance of a complete ophthalmic evaluation in cases presenting with NVG of unclear etiology to exclude the presence of a potentially life-threatening intraocular tumor.

Type of bony involvement predicts genomic subgroup in sphenoid wing meningiomas.

PURPOSE: As sphenoid wing meningiomas (SWMs) are associated with varying degrees of bony involvement, we sought to understand potential relationships between genomic subgroup and this feature. METHODS: Patients treated at Yale-New Haven Hospital for SWM were reviewed. Genomic subgroup was determined via whole exome sequencing, while the extent of bony involvement was radiographically classified as no bone invasion (Type I), hyperostosis only (Type II), tumor invasion only (Type III), or both hyperostosis and tumor invasion (Type IV). Among additional clinical variables collected, a subset of tumors was identified as spheno-orbital meningiomas (SOMs). Machine-learning approaches were used to predict genomic subgroups based on pre-operative clinical features. RESULTS: Among 64 SWMs, 53% had Type-II, 9% had Type-III, and 14% had Type-IV bone involvement; nine SOMs were identified. Tumors with invasion (i.e., Type III or IV) were more likely to be WHO grade II (p: 0.028). Additionally, tumors with invasion were nearly 30 times more likely to harbor NF2 mutations (OR 27.6; p: 0.004), while hyperostosis only were over 4 times more likely to have a TRAF7 mutation (OR 4.5; p: 0.023). SOMs were a significant predictor of underlying TRAF7 mutation (OR 10.21; p: 0.004). CONCLUSIONS: SWMs with invasion into bone tend to be higher grade and are more likely to be NF2 mutated, while SOMs and those with hyperostosis are associated with TRAF7 variants. Pre-operative prediction of molecular subtypes based on radiographic bony characteristics may have significant biological and clinical implications based on known recurrence patterns associated with genomic drivers and grade.

Inferior Rectus and Inferior Oblique Muscle Transections with Medial Rectus Muscle Partial Avulsion, following Metal Hook Injury.

Avulsion or transection of three extraocular muscles following trauma is a rare finding, and there are few case reports and series discussing the approach to surgical repair. The authors report a case of a penetrating metal hook injury resulting in partial avulsion of a medial rectus muscle and transection of the inferior rectus and inferior oblique muscles. This case highlights the importance of identification and primary repair of a complete inferior rectus muscle transection and a partial medial rectus muscle avulsion with an excellent functional outcome.

Simultaneous Orbital and Intracranial Abscesses in 17 Cases.

PURPOSE: To describe the demographics, clinical presentation, treatment, and outcomes of a rare cohort with simultaneous orbital and intracranial abscesses. METHODS: A historical cohort study of 17 patients with simultaneous orbital and intracranial abscesses between 2010 and 2018 was performed. The demographics, location of abscesses, treatment, and outcomes of these patients were analyzed. RESULTS: The mean age was 26.9 years (range 5-83 years). Fourteen patients (82%) were male. In this cohort, the most common orbital abscess location was the superior orbit, involved in 14 patients (82%). The most common site of intracranial abscess was the frontal lobe, involved in 16 patients (94%). Concurrent sinus disease was present in 16 patients (94%). Surgical evacuation was the standard of treatment, with 94% of patients undergoing at least one surgical procedure. Streptococcus species were the most common, isolated from 6 sinus cultures (43%), 3 orbitotomy cultures (21%), and 4 craniectomy cultures (36%). Staphylococcus species were also common. Most patients (94%) had stable or improved mental status and visual function at the conclusion of their treatment. CONCLUSIONS: Simultaneous orbital and intracranial abscesses are rare. Local invasion from the orbit into the intracranial space may occur from direct spread, thus superior orbital abscesses pose the greatest risk for intracranial spread. Additional factors such as infection with Streptococcus and Staphylococcus species as well as male sex appear to be risk factors for intracranial spread. For those who develop intracranial abscesses, young age and absence of seizures or altered mental status at presentation may be associated with favorable outcomes.

Genetic characterization of an aggressive optic nerve pilocytic glioma.

Optic nerve glioma (ONG) is a rare, typically slow-growing WHO I grade tumor that affects the visual pathways. ONG is most commonly seen in the pediatric population, in association with neurofibromatosis type 1 syndrome. However, sporadic adult cases may also occur and may clinically behave more aggressively, despite benign histopathology. Genetic characterization of these tumors, particularly in the adult population, is lacking. A 39-year-old female presented with 1 month of progressive left-sided visual loss secondary to a enhancing mass along the left optic nerve sheath. Initial empiric management with focal radiotherapy failed to prevent tumor progression, prompting open biopsy which revealed a WHO I pilocytic astrocytoma of the optic nerve. Whole-exome sequencing of the biopsy specimen revealed somatic mutations in NF1,FGFR1 and PTPN11 that may provide actionable targets for molecularly guided therapies. Genetic characterization of ONG is lacking but is needed to guide the management of these rare but complex tumors. The genomic alterations reported in this case contributes to understanding the pathophysiology of adult sporadic ONG and may help guide future clinical prognostication and development of targeted therapies.

Dabrafenib and Trametinib for BRAF-Mutated Conjunctival Melanoma.

BACKGROUND: Conjunctival melanoma is a potentially lethal malignancy of the ocular surface. There have been no therapeutic advancements made in the past several decades despite increasing prevalence of the disease. METHODS: The authors report the case of a 52-year-old Caucasian male with unresectable, recurrent conjunctival melanoma with V600 BRAF mutation who was treated with systemic BRAF/MEK inhibition. RESULTS: There was complete regression of local disease within the first 9 months. The patient remains without local recurrence or systemic metastasis at 1 year. CONCLUSION: This is the first reported case of conjunctival melanoma with complete response to BRAF/MEK inhibition. As long as targeted therapy remains an option, patients with conjunctival melanoma should undergo mutational profiling of their tumor.

Epidemiology, outcomes, and prognostic factors of orbital lymphoma in the United States.

PURPOSE: We performed an epidemiological study of orbital lymphoma in the United States to determine how histological subtypes confer differing prognosis, and understand other factors associated with survival. METHODS: All patients in the Surveillance, Epidemiology and End Results database diagnosed with a histologically confirmed orbital lymphoma between 1973 and 2014 were included. Exclusion criteria included diagnosis at autopsy and the presence of other malignancies. Measures included patient demographic information, histological subtype and treatment modalities. Outcomes included overall and disease specific survival. RESULTS: Of the 1504 cases identified, 702 were male (46.7%, mean age: 64.4 years, standard deviation [SD]: 15.3) and 802 were female (53.3%, mean age: 67.5 years, SD: 14.3). Mucosal associated lymphoid tissue (MALT) (49.5%) and diffuse large B cell lymphoma (DLBCL) (19.5%) were the two most common histologic subtypes. MALT lymphoma conferred the best prognosis (10-year cancer specific survival [CSS] 90.2%, 95% Confidence Interval [CI] 87.4% - 93.1%) and DLBCL conferred the worst prognosis (10-year CSS 68.6%, 95% CI 62.5% - 75.3%) (p < .001, log-rank test). Older age (Hazard Ratio [HR]: 3.71, 95% Confidence Interval [CI]: 2.94-4.66, p < .001), male sex (HR: 1.22, 95% CI: 1.039-1.441, p = .015), no radiation (HR: 1.72, 95% CI: 1.46-2.02, p < .001) and DLBCL histology were significant predictors of worse overall survival. CONCLUSIONS: DLBCL histology confers the worst outcomes whereas MALT lymphoma confers the best outcome in orbital lymphoma. Age, gender, and radiation treatment also influence survival. These epidemiological results can be used clinically to communicate outcomes on the basis of patient characteristics and disease histology.

Visual improvement in amblyopic eye following treatment-induced vision loss in dominant eye with uveal melanoma.

OBJECTIVE: To determine the frequency and amount of visual improvement in amblyopic eyes of adults following visual loss in the dominant eye resulting from treatment of uveal melanoma. METHODS AND ANALYSIS: Retrospective case series of adult patients with amblyopia and dominant eye visual loss resulting from treatment of uveal melanoma. Review of best-corrected visual acuity (BCVA) in each eye (amblyopia eye vs melanoma eye) at date first seen and over time following treatment of uveal melanoma. BCVA in each eye was graded as improved (>2 logarithm of minimal angle of resolution (logMAR) lines) or unimproved (<2 logMAR lines). RESULTS: Twenty-one patients that met the inclusion criteria. Mean age at presentation was 56 years (range 39-73 years). Following treatment of the uveal melanoma and decline of BCVA in the dominant, the BCVA in the amblyopic eye improved in 11/21 (52%; 95% CI 30% to 74 %) patients. The degree of visual loss in the melanoma eye was to the level of the amblyopic eye or worse in 14 patients. In this group, BCVA improved in the amblyopic eye in 9/14 (64%; 95% CI 35% to 87 %) patients. Of these nine with improved eyes, the mean starting visual acuity was logMAR 0.6 (20/80) with mean improvement of logMAR 0.4 (4 lines±0.13 (range 0.2-0.6). Eight of nine eyes achieved a BCVA of 20/25 (n=3) or 20/20 (n=5). CONCLUSION: Visual acuity in the amblyopic eye of adults can improve following visual loss in the contralateral dominant eye associated with treatment for uveal melanoma.

Chondrosarcoma Metastasis to the Choroid.

We report a rare case of chondrosarcoma metastatic to the choroid. A 64-year-old male with a history of chondrosarcoma metastatic to the lungs and to the spine presented with blurred vision. A choroidal tumor was found. Fine-needle biopsy confirmed the histologic identity of the tumor as chondrosarcoma. Metastatic spread of chondrosarcoma to the eye is extremely rare. When present, lesions may grow rapidly, and systemic prognosis is poor. Co-management with medical oncology is of utmost importance. This is the third case of chondrosarcoma metastatic to the choroid in the literature and the first with bilateral involvement.

Novel Eye Plaque Designs for Brachytherapy of Iris and Ciliary Body Melanoma and the First Clinical Application.

BACKGROUND: While traditional eye plaque brachytherapy can be used for the treatment of iris melanoma, it faces challenges of poor patient tolerability due to cornea-plaque touch caused by radius of curvature mismatch and potential dosimetric inaccuracy from incomplete coverage. We present novel plaque designs and the first clinical application of the plaques for iris melanoma. METHODS: Two dome-shaped plaques (EP2132 and EP1930) were designed to vault above the cornea to treat tumors of the iris and ciliary body. Image-based treatment planning of the first 2 clinical cases using the EP2132 plaque covered the tumor base plus a 2 mm margin and the involved ciliary body with at least 75 Gy to the tumor apex. RESULTS: The tumors decreased in size following treatment. The patients tolerated the treatment well. There was no adverse event associated with the traditional iris plaques, such as decreased vision, pain, corneal edema, glaucoma, or cataract. CONCLUSION: The novel dome-shaped plaques for the treatment of iris melanoma provide effective dose distribution, improved surgical maneuverability, and increased tolerability for the patient. This plaque model can be used to treat iris melanoma of various sizes, configurations, and locations, including the ciliary body. The need for a customized plaque platform for each patient is minimized.
