RESUMO

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.

RESUMO

PURPOSE: This study evaluated the functional outcome and ocular side effects of patients receiving proton beam radiotherapy (PBR) for the treatment of iris melanoma (IM). DESIGN: This retrospective study analyzed prospectively collected data. PARTICIPANTS: Patients with IM who underwent PBR as a primary treatment. METHODS: Treatment was given in the form of whole PBR (wPBR: n = 51) or segmental PBR (sPBR: n = 98). MAIN OUTCOME MEASURES: Visual acuity (VA) and side effects were divided into ocular surface disease (OSD), secondary glaucoma, or cataract development. RESULTS: A total of 149 eyes of 149 patients with a mean age of 53.9 ± 16.0 years were included. Tumor recurrence developed in 3 patients (wPBR: 1/51; sPBR: 2/98). Ocular surface disease was observed in 78.4% of the wPBR group (40/51) and 25.5% of the sPBR group (25/98) (P < 0.001) after 0.7 ± 1.2 years and 1.1 ± 0.9 years, respectively. The main side effect was dry eye syndrome in both groups, but severe side effects such as limbal stem cell failure were found only in the wPBR group (4/51; 7.8%). Secondary glaucoma developed in 31.4% of the wPBR group (16/51) compared with 1.0% in the sPBR group (1/98; P < 0.001). Glaucoma control was generally achieved with eye drops, whereas surgery was necessary in 5 patients (wPBR: 4/51, 7.8%; sPBR: 1/98, 1%). Cataract surgery was performed in 47.9% of the wPBR group (23/48) and 19.8% of the sPBR group (19/96) (P < 0.001). Before treatment, VA was 0.14 ± 0.27 logarithm of the minimum angle of resolution (logMAR) in the wPBR group and 0.04 ± 0.19 logMAR in the sPBR group. A worsening was seen in the wPBR group (0.55 ± 0.16 logMAR; P < 0.001) 6 months after radiotherapy, which normalized after 12 months (0.15 ± 0.30 logMAR; P = 0.17). In the sPBR group, no such decrease in VA was observed (6 months: 0.03 ± 0.22 logMAR, P = 0.54; 12 months: 0.04 ± 0.21 logMAR, P = 0.98). CONCLUSIONS: Our results demonstrate that PBR is a very successful treatment option for patients with IM, showing a high tumor control rate and relatively low complication profile. Tumor recurrence was a rare event, and secondary enucleation was not necessary in any patient. Side effects are commonly seen, but severe side effects such as limbal stem cell failure or secondary glaucoma mainly developed after wPBR. These results are important for clinical decision making and discussion with the patient regarding this form of radiotherapy.

RESUMO

PURPOSE: To report a previously unrecognized choroidal melanoma clinical feature termed tumor-associated retinal pigmentation (TARP) and determine any correlation with tumor biology. DESIGN: Imaging and histologic analysis of a retrospective cohort of patients. PARTICIPANTS: Patients with choroidal melanoma identified as having TARP on funduscopy at the Liverpool Ocular Oncology Centre (LOOC), United Kingdom, from January 2020 through January 2023. METHODS: Clinical and imaging characteristics of patients diagnosed with choroidal melanoma and exhibiting TARP on fundoscopy were documented. Details of these choroidal melanomas were collated and correlated with histopathology and molecular genetic reports. The chromosome 3 status of each tumor was assessed. In enucleated samples, immunostaining was undertaken to determine the nature of the TARP using specific markers (CD68 and MelanA). MAIN OUTCOME MEASURES: Features of TARP on widefield fundus color imaging, fundus autofluorescence (FAF), and OCT were described. Tumor chromosome 3 status and the immunoprofile of the TARP also were collated. RESULTS: Tumor-associated retinal pigmentation had a prevalence rate of 7.47 per 100 cases of choroidal melanoma at the LOOC. Twenty-three eyes with TARP were analyzed, with a mean age of 71.4 years (range, 51-88 years). The median largest basal diameter was 16.10 mm (range, 9.17-21.32 mm), and the mean tumor thickness was 8.04 mm (range, 1.40-13.80 mm). Tumor-associated retinal pigmentation was observed on widefield color fundus imaging, with hypofluorescence on FAF images and represented hyperreflective foci located in intraretinal and subretinal spaces on OCT scans. Seventeen patients (73.9%) underwent enucleation, and 6 patients (26.1%) underwent globe-sparing treatment. Molecular genetic analysis of 20 choroidal melanomas (after enucleation or radiotherapy biopsy) revealed monosomy 3 in 18 tumors (90%). Immunostaining of the TARP in enucleated eyes showed CD68+ melanophages in all 17 patients appearing as scattered cells and aggregates; MelanA findings were negative. CONCLUSIONS: Tumor-associated retinal pigmentation represents tumor-associated macrophages, not melanocytes, within intraretinal and subretinal spaces of larger choroidal melanomas. Radiation treatments need not involve this area in the treatment plan, minimizing radiation-related complications. This novel clinical sign seems to be linked to tumors of high metastatic-risk clinical and genetic characteristics, with a preponderance having monosomy 3 anomalies.

RESUMO

This review provides an overview of retinal vascular disorders that are less frequent in Germany and Europe compared to diabetic retinopathy and retinal venous or arterial occlusive disorders. The knowledge of these disorders is important for the differential diagnosis of retinal vascular disorders as well as potentially associated systemic disorders. In the current part one epidemiology, pathophysiology, clinical presentation, and therapy are discussed for hypertensive retinochoroidopathy, ocular ischemic syndrome, retinal alterations in sickle cell disease, Eales disease, radiation retinopathy, peripheral exudative hemorrhagic chorioretinopathy, and retinal disorders associated with pregnancy.

RESUMO

BACKGROUND: Technological advances have led to cancer prognostication that is increasingly accurate but often unalterable. However, a reliable prognosis of limited life expectancy can cause psychological distress. People should carefully consider offers of prognostication, but little is known about how and why they decide on prognostication. Using uveal melanoma (UM) patients, we aimed to identify (i) how and why do people with UM decide to accept prognostication and (ii) alignment and divergence of their decision-making from conceptualizations of a 'well-considered' decision. METHODS: UM provides a paradigm to elucidate clinical and ethical perspectives on prognostication, because prognostication is reliable but prognoses are largely nonameliorable. We used qualitative methods to examine how and why 20 UM people with UM chose prognostication. We compared findings to a template of 'well-considered' decision-making, where 'well-considered' decisions involve consideration of all likely outcomes. RESULTS: Participants wanted prognostication to reduce future worry about uncertain life expectancy. They spontaneously spoke of hoping for a good prognosis when making their decisions, but largely did not consider the 50% possibility of a poor prognosis. When pressed, they argued that a poor outcome at least brings certainty. CONCLUSIONS: While respecting decisions as valid expressions of participants' wishes, we are concerned that they did not explicitly consider the realistic possibility of a poor outcome and how this would affect them. Thus, it is difficult to see their decisions as 'well-considered'. We propose that nondirective preference exploration techniques could help people to consider the possibility of a poor outcome. PATIENT OR PUBLIC CONTRIBUTION: This paper is a direct response to a patient-identified and defined problem that arose in therapeutic and conversational discourse. The research was informed by the responses of patient participants, as we used the material from interviews to dynamically shape the interview guide. Thus, participants' ideas drove the analysis and shaped the interviews to come.

RESUMO

A number of patient-reported outcomes (PROs) predict increased mortality after primary cancer treatment. Studies, though, are sometimes affected by methodological limitations. They often use control variables that poorly predict life expectancy, examine only one or two PROs thus not controlling potential confounding by unmeasured PROs, and observe PROs at only a single point in time. To predict all-cause mortality, this study used control variables affording good estimates of life expectancy, conducted multivariate analyses of multiple PROs to identify independent predictors, and monitored PROs two years after diagnosis. We recruited a consecutive sample of 824 patients with uveal melanoma between April 2008 and December 2014. PROs were variables shown to predict mortality in previous studies; anxiety, depression, visual and ocular symptoms, visual function impairment, worry about cancer recurrence, and physical, emotional, social and functional quality of life (QoL), measured 6, 12 and 24 months after diagnosis. We conducted Cox regression analyses with a census date of December 2018. Covariates were age, gender, marital and employment status, self-reported co-morbidities, tumor diameter and thickness, treatment modality and chromosome 3 mutation status, the latter a genetic mutation strongly associated with mortality. Single predictor analyses (with covariates), showed 6-month depression and poorer functional QoL predicting mortality, as did 6-12 month increases in anxiety and 6-12 month decreases in physical and functional QoL. Multivariate analyses using all PROs showed independent prediction by 6-month depression and decreasing QoL over 6-12 months and 12-24 months. Elevated depression scores six months post-diagnosis constituted an increased mortality risk. Early intervention for depressive symptoms may reduce mortality.

RESUMO

Uveal Melanoma (UM) is the most common primary intra-ocular tumor in adults. New diagnostic procedures and basic science discoveries continue to change our patient management paradigms. A recent meeting of the European Vision Institute (EVI) special interest focus group was held on "Outcome Measures of New Technologies in Uveal Melanoma", addressing the latest advances in UM, starting with genetic developments, then moving on to imaging and treatment of the primary tumor, as well as to investigating the most recent developments in treating metastases, and eventually taking care of the patient's wellbeing. This review highlights the meeting's presentations in the context of the published literature.

RESUMO

The COVID-19 pandemic has had an unprecedented impact on the National Health Service in United Kingdom. The UK Ocular Oncology Services evaluated the impact on the adult eye cancer care in the UK. All four adult Ocular Oncology centres participated in a multicentre retrospective review comparing uveal melanoma referral patterns and treatments in a 4-month period during the national lockdown and first wave of the COVID-19 pandemic in 2020 with corresponding periods in previous 2 years. During the national lockdown, referral numbers and confirmed uveal melanoma cases reduced considerably, equalling to ~120 fewer diagnosed uveal melanoma cases compared to previous 2 years. Contrary to the recent trend, increased caseloads of enucleation and stereotactic radiosurgery (p > 0.05), in comparison to fewer proton beam therapy (p < 0.05), were performed. In the 4-month period following lockdown, there was a surge in clinical activities with more advanced diseases (p < 0.05) presenting to the services. As the COVID-19 pandemic continues to mount pressure and reveal its hidden impact on the eye cancer care, it is imperative for the Ocular Oncology Services to plan recovery strategies and innovative ways of working.

RESUMO

PURPOSE: To evaluate the diagnostic accuracy of routinely used tests of visual function and retinal morphology compared with fundus fluorescein angiography (FFA) to detect onset of active macular neovascularization in unaffected fellow eyes of patients with unilateral neovascular age-related macular degeneration (nAMD). DESIGN: Prospective diagnostic accuracy cohort study conducted in 24 eye clinics in the United Kingdom over 3 years. PARTICIPANTS: Older adults (>50 years) with recently diagnosed unilateral nAMD with a fellow (study) eye free of nAMD. METHODS: Self-reported vision, Amsler, clinic-measured visual acuity (VA), fundus assessment, and spectral domain OCT. The reference standard is FFA. MAIN OUTCOME MEASURES: Sensitivity and specificity of the 5 index tests. RESULTS: Of 552 participants monitored for up to 3 years, 145 (26.3%) developed active nAMD in the study eye, of whom 120 had an FFA at detection and constituted the primary analysis cohort. Index test positives at nAMD detection in those confirmed by FFA were self-reported vision much worse (5), distortion on Amsler (33), 10-letter decrease in acuity from baseline (36), fundus examination (64), and OCT (110). Percentage index test sensitivities were: self-reported vision 4.2 (95% confidence interval [CI], 1.6-9.8); Amsler 33.7 (95% CI, 25.1-43.5); VA 30.0 (95% CI, 22.5-38.7); fundus examination 53.8 (95% CI, 44.8-62.5); and OCT 91.7 (95% CI, 85.2-95.6). All 5 index test specificities were high at 97.0 (95% CI, 94.6-98.5), 81.4 (95% CI, 76.4-85.5), 66.3 (95% CI, 61.0-71.1), 97.6 (95% CI, 95.3-98.9), and 87.8 (95% CI, 83.8-90.9), respectively. The combination of OCT with one other index test that was a secondary outcome measure increased sensitivity marginally and decreased specificity for all combinations except fundus examination. CONCLUSIONS: Tests of self-reported change in vision, unmasking of new distortion, measurements of acuity, and fundus checks to diagnose active nAMD performed poorly in contrast to OCT. Our findings support a change to guidelines in clinical practice to monitor for onset of nAMD.

RESUMO

OBJECTIVE: Cancer survivors commonly experience long-term anxiety and depression. Anxiety and depression might result from problems emerging during survivorship rather than illness and treatment. This study tested three potential causal paths: (a) concerns about physical symptoms and functional problems and fear of cancer recurrence (FCR) arising during survivorship directly cause anxiety and depression, (b) an indirect path whereby FCR mediates effects of concerns about physical symptoms and functional problems on anxiety and depression, and (c) a reciprocal path whereby anxiety and depression cause concerns about physical symptoms and functional problems and FCR, which exacerbate later anxiety and depression. METHODS: Sample of 453 uveal melanoma survivors who completed observations 6-, 12-, 24-, 36-, 48- and 60-months post-diagnosis and did not miss two consecutive observations. Cross-lagged analyses were conducted to predict Hospital Anxiety and Depression Scale subscale scores. Symptoms and functional problems were measured using the EORTC OPT 30 scale, and FCR operationalised by the EORTC OPT 30 worry about recurrence scale. Covariates were age, gender, treatment modality, and visual acuity of the fellow eye and chromosome-3 status (which accurately predicts 10-year survival), worry and anxiety or depression. RESULTS: All paths received some support, although the indirect path emerged only for anxiety in females. Concerns about physical symptoms, functional problems, and FCR originated in survivorship and appeared to both influence and be influenced by anxiety and depression. CONCLUSIONS: Findings emphasise the importance of actively monitoring survivors to prevent, detect, and intervene in the development of anxiety and depression during survivorship.

RESUMO

PURPOSE: To investigate whether early detection and treatment of uveal melanoma by screening was associated with a lower mortality rate. METHODS: Retrospective assessment of prospectively collected data comparing 132 patients with uveal melanoma referred by the National Diabetic Screening Service with 608 control patients referred through other means. RESULTS: Mean tumor diameter was smaller in the diabetic screening group (11.1 mm vs. 12.5 mm) as was tumor thickness (3.4 mm vs. 5.4 mm). The prevalence of high-risk monosomy 3 was also lower (17/40, 43% vs. 62/110, 56%). Despite a higher rate of systemic comorbidities in the patients diagnosed through screening and despite older age at diagnosis, the 5-year all-cause mortality was similar in both groups (17% vs. 20%); however, the metastatic mortality was lower in the diabetic screening group (11/132, 8% vs. 95/608, 16%). CONCLUSION: Despite higher rates of comorbidities, the patients detected at diabetic screening had a lower 5-year mortality rate. The diabetic screening programme enabled detection and treatment of posterior uveal melanomas at an earlier stage. However, the confounding factors of lead and length time bias are not to be ignored.

RESUMO

This review article gives an overview of the epidemiology, relevant risk factors, clinical characteristics and the diagnostic approach of rhegmatogenous retinal detachment. Rhegmatogenous retinal detachment is an ophthalmologic emergency needing immediate surgical treatment. Main risk factors are retinal tears, myopia and previous cataract surgery. For patients with symptoms of posterior vitreous detachment, indirect ophthalmoscopy under pupil dilatation is necessary to diagnose retinal tears or retinal detachment. Differential diagnoses are tractive or exudative forms of retinal detachment or retinoschisis.

RESUMO

The customary doctor and patient interactions are currently undergoing significant changes through technological advances in imaging and data processing and the need for reducing person-to person contacts during the COVID-19 crisis. There is a trend away from face-to-face examinations to virtual assessments and decision making. Ophthalmology is particularly amenable to such changes, as a high proportion of clinical decisions are based on routine tests and imaging results, which can be assessed remotely. The uptake of digital ophthalmology varies significantly between countries. Due to financial constraints within the National Health Service, specialized ophthalmology units in the UK have been early adopters of digital technology. For more than a decade, patients have been managed remotely in the diabetic retinopathy screening service and virtual glaucoma clinics. We describe the day-to-day running of such services and the doctor and patient experiences with digital ophthalmology in daily practice.

RESUMO

OBJECTIVE: We examined the role of posttreatment symptoms and functional problems and of worry about recurrent disease (WREC) in predicting probable anxiety and depression cases 24 months after diagnosis in survivors of posterior uveal melanoma. We examined whether WREC mediates links between symptoms, functional problems, and probable anxiety and depression cases. METHODS: Prospective cohort study of 261 treated uveal melanoma survivors 6, 12, and 24 months after diagnosis. Hierarchical logistic regression analyses predicting anxiety and depression 24 months after diagnosis identified by Hospital Anxiety and Depression Scale cutoff scores. Symptoms, functional problems, and WREC 6-month posttreatment were entered into the analyses as predictors, then the same variables at 12 months. We controlled anxiety or depression at 6 and 12 months and chromosome 3 status, which accurately predicts 10-year survival. Mediation of links between 6-month symptoms and functional problems and 24-month anxiety and depression by 12-month WREC was tested. RESULTS: Anxiety caseness at 24 months was predicted by 6-month ocular irritation, headache, and functional problems and 12-month WREC. Depression caseness at 24 months was predicted by 6-month headache and functional problems. Worry about recurrent disease at 12 months mediated prediction of anxiety caseness by 6-month symptoms and functional problems. Chromosome 3 status predicted neither anxiety nor depression. CONCLUSIONS: Survivors reporting symptoms, functional problems, and WREC should be monitored for anxiety and depression. Appropriate reassurance that symptoms do not signify future disease might help prevent anxiety.

RESUMO

Retinal toxicity/biocompatibility of medical devices in direct contact with the retina is an important subject for clinicians and scientists. As these effects are not very frequent, there is also a relative lack of information for many clinicians. The past has taught us multiple times that there is a significant safety problem associated with severe loss of vision in affected patients. In this review, we want to classify medical products that are used in the back of the eye, describe recent examples of toxicity, critically reflect on the regulations that exist and suggest improvements that can be done to ensure patient safety without hindering innovation. METHODS: Critical review of the recent papers and personal experience of the authors in this issue. Medical devices used in the back of the eye and recent examples of toxicity are described, regulations that exist are critically reflected and improvements suggested that can ensure patient safety without hindering innovation. RESULTS: There is clear evidence of toxicity after intraocular surgery in any category. Some cytotoxic indirect methods have failed in detecting this toxicity. Some ISO rules do not seem appropriate. Postmarketing safety is missing. There is little data on this issue. CONCLUSIONS: The absence of a clear regulation of the production, purification and evaluation of the toxic effects of the medical devices supposes the possibility that products are not sufficiently safe to obtain the CE mark.

RESUMO

BACKGROUND: To report a case of metastatic hepatocholangiocarcinoma to the vitreous and retina. CASE PRESENTATION: A 70-year-old male, who was recently diagnosed with hepatocholangiocarcinoma, was complaining of floaters in his right eye over the past 5 months and was referred to the Liverpool Ocular Oncology Centre. On presentation, his visual acuity in the right eye was 6/24. Fundus exam revealed a whitish, unilateral, full-thickness retinal lesion at the inferotemporal arcade of his right eye, with vitreous infiltration and subretinal fluid. The patient underwent 25G pars plana vitrectomy with biopsy, resection of the lesion and intravitreal bevacizumab injection. Histopathology testing of the surgical specimens confirmed the diagnosis of metastatic carcinoma to the eye. Two months postoperatively his visual acuity had improved to 6/7.5 and there was no sign of active disease in his right eye, while 9 months postoperatively his visual acuity decreased to 6/9.5 due to developing nuclear sclerotic cataract in his right eye. CONCLUSION: The current report presents the first case of a hepatocholangiocarcinoma metastasis to the vitreous and retina.

RESUMO

PURPOSE: To compare hydroxyapatite with acrylic implants after enucleation for uveal melanoma with respect to eyelid position, ocular motility, implant complications, and patient satisfaction. METHODS: Patients undergoing primary enucleation for uveal melanoma between May 2005 and November 2012 at the Liverpool Ocular Oncology Centre, United Kingdom, were randomized between hydroxyapatite and acrylic implants. Questionnaires were sent to patients and ocularists to comment on the main outcomes. RESULTS: A total of 416 patients were recruited in the study, of whom 281 were included, with 49.5% (139/281) and 50.5% (142/281) receiving a hydroxyapatite (HA) or acrylic (AC) implant. Mailed questionnaires completed at ≥18 months by patients showed no significant differences between the groups in eyelid position, prosthetic motility, socket complications, and patient satisfaction. Complications included implant extrusion (1% vs 4%), enophthalmos (26% vs 26%), and superior sulcus deformity (24% vs 24%) with HA and AC implants, respectively, (Fisher exact test p > 0.0125 in all, Bonferroni correction). Questionnaires completed by ocularists indicated no significant differences in eyelid opening, prosthetic motility, and other complications at 6 months (Fisher exact test, p > 0.05 in all); there was a higher prevalence of ptosis with AC than HA implants (46% vs 25%, p = 0.03) and a greater need for ocularists' treatment with HA than AC (50% vs 28%, p = 0.03). CONCLUSIONS: Patient-reported outcomes after enucleation for uveal melanoma indicate no major differences between hydroxyapatite and acrylic implants in surgical outcomes and patient satisfaction. There was a higher prevalence of ptosis with AC and a greater need of ocularists' visits with HA at around 6 months observed by ocularists.
