PURPOSE:Prior studies have shown that nuclear reactivity for BRCA1-associated protein-1 (BAP1) yields prognostic information for paraffin-embedded uveal melanomas. Lacking are immunocytochemical studies of BAP1 on fine needle aspiration biopsies of uveal melanoma that correlate with prognosis or other markers of prognosis. Our purpose was to fill this gap. DESIGN:Experimental laboratory study. METHODS:Fine needle aspiration biopsies were performed prospectively on 113 patients with uveal melanomas, garnering limited subsets of cases for comparison. Agreement between immunocytochemistry for BAP1 nuclear staining vs chromosome 3 ploidy analysis and gene expression profiling was assessed by 2 × 2 contingency table analysis. RESULTS:The presence or absence of suppression of nuclear expression of BAP1 was strongly associated (73%, P = .000002) with monosomy and disomy chromosome 3, respectively. BAP1 nuclear expression was also correlated with gene expression profiling. Chromosome 3 ploidy analysis correlated with gene expression profiles. CONCLUSION:When adequate material is obtained, immunocytology using BAP1 is a potentially informative tool for prognostication of uveal melanoma.

Local treatment failure after globe-conserving therapy for choroidal melanoma is a surgical complication with significant morbidity to the vision and eye. Few reports in the literature have addressed this complication exclusively. A review of the published literature with reference to local treatment failure in the management of choroidal melanoma was performed to make known the potential differences in failure rates between treatment modalities and methods. A search of the literature regarding local treatment failure was performed to identify relevant studies using combinations of the following keywords on PubMed: uveal melanoma, choroidal melanoma, local recurrence, local failure, endoresection, gamma knife, radiotherapy, helium, iodine, proton, palladium, ruthenium, trans-scleral resection, transpupillary thermotherapy. Further studies were found by searching the text and references of previously identified studies for articles reporting local treatment failure rates in choroidal melanoma. Among the 49 studies identified, the local treatment failure rate ranged from 0% to 55.6%, with follow-up ranging from 10 to 150 months. The two most widely used forms of radiation therapy, iodine-125 and ruthenium-106 brachytherapy, were both associated with a local recurrence rate of 9.6%. The weighted-average of treatment failure in all radiation therapies was 6.15% compared with 18.6% in surgical and 20.8% in laser therapies. Rates of local treatment failure for globe-conserving therapy of choroidal melanoma varied widely between modalities and between centres using similar modalities. Radiation therapy overall resulted in lower local treatment failures compared with surgical or transpupillary thermotherapy.

Conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma has been well-described, but rarely do these lesions demonstrate intraocular involvement. We report a case of conjunctival MALT lymphoma with intraocular involvement and novel spectral-domain ocular coherence tomography (SD-OCT) findings. A 75-year-old woman with biopsy-proven MALT lymphoma of the conjunctiva presented with ipsilateral yellowish diffuse choroidal infiltrates on fundoscopic examination. Choroidal involvement was documented clinically, on ultrasonography, on fluorescein angiography, and by SD-OCT. Treatment consisted of 3 weeks of oral doxycycline and six cycles of systemic chemotherapy with cyclophosphamide, vincristine, prednisone, and rituximab. There was no evidence of progression or recurrence of MALT lymphoma after 9 months of follow-up. Despite complete resolution of clinical findings, ultrasound, and fluorescein angiography, the choroidal lesions remained unchanged on SD-OCT. Choroidal involvement of conjunctival MALT is rare, and can be successfully treated. Persistence of irregularities on SD-OCT did not influence management in the presence of clinical improvement and resolution on ultrasonography and fluorescein angiography.

BACKGROUND/OBJECTIVES: The purpose of this study is to report cases of choroidal melanoma that developed extrascleral tumour recurrence after treatment with iodine-125 brachytherapy. SUBJECTS/METHODS: In this single-institution retrospective observational case series, all instances of biopsy-confirmed orbital melanoma after known intraocular melanoma were reviewed. Tumour characteristics, clinical course, time to recurrence, cytogenetics of initial tumour and recurrence, and presence of intraocular recurrence were documented. RESULTS: Five cases of orbital melanoma following treatment with plaque radiotherapy are described. Tumour staging was Ia (1), IIa (2), and IIb (2). The primary lesion in four of the five appeared to have undergone complete regression for an average of 2 years, with the orbital melanoma developing after this interval. Recurrence of the intraocular tumour was seen in conjunction with an extrascleral component in two cases. Four cases ultimately underwent enucleation or exenteration; three had evidence of direct extension of tumour through the sclera. Four cases in this series had molecular characteristics associated with high metastatic risk (three patients with monosomy 3, one with BAP1 mutation). CONCLUSIONS: High-risk tumour biology may predispose to late appearance of extrascleral melanoma despite optimal treatment and adequate control of the intraocular tumour. Extended follow-up with detailed orbital examination and imaging is recommended for this population.

Aim

We report patient safety and intraocular pressure (IOP) control after placement of a glaucoma drainage device (GDD) in eyes with a history of treated malignant uveal melanoma.

Methods

A retrospective review of the records of patients with uveal melanoma was performed. Outcomes were local tumor recurrence, rate of metastases, and to-nometric success, based on survival curves, defined as IOP < 21 mm Hg.

Results

Eleven eyes with choroidal melanoma, 4 with iris melanoma, and 1 with ciliary body melanoma were followed for a median (interquartile range) of 2.1 (1.1-3.2) years. Two subjects developed liver metastases; one had monosomy 3 and tumor gene expression profile class 2. The other case with ciliary body melanoma was negative for monosomy 3. There were no cases of local treatment failure. Mean preoperative IOP decreased from 30.5 ± 7.7 to 15.9 ± 8.1 mm Hg at 1 year after surgery (1-year success rate 80%).

Conclusions

Our case series with a median follow-up of 2 years shows that placing a GDD in patients with treated uveal melanoma does not expose patients to greater risk of local or extraocular recurrence. A larger series and longer follow-up time are required to fully evaluate the safety of GDDs in this clinical scenario.

Aims

To assess quality of life (QoL) indices and their associations with treatment modality, sociodemographics and cancer-related needs in choroidal melanoma patients.

Methods

Patients (N=99) treated at the University of California, Los Angeles, for choroidal melanoma within the prior 5 years (M=2.05) completed questionnaires assessing demographics, cancer-related needs, vision-specific QoL, depressive symptoms and concern about recurrence. Visual acuity, comorbidities, treatment modality (radiotherapy, enucleation) and years since diagnosis were gathered from medical records. Primary analyses were multiple regressions.

Results

Although concern about cancer recurrence was elevated, QoL was better than in other oncology samples and comparable with healthy samples on some outcomes. Enucleation was associated with worse vision-specific QoL, and presence of comorbid diseases was associated with worse vision-specific QoL, depressive symptoms and concern about cancer recurring (all p values<0.05). Patients who experienced at least one stressful life event in the past year (vs no events) reported more depressive symptoms (p<0.01). Report of more unmet cancer needs was associated with worse vision-specific QoL, depressive symptoms and more concern about recurrence (all p values<0.05), uniquely explaining 4%-12% of the variance.

Conclusions

For choroidal melanoma patients, an average of 2 years after treatment, the number of physical comorbidities and unmet cancer needs were the strongest correlates of poorer QoL.

Retinal cavernous hemangiomas are rare vascular anomalies, and can be associated with cerebral cavernous malformations (CCM). Distinct mutations have been reported in patients who have both CCMs and retinal cavernous hemangiomas. Fluorescein angiography, spectral domain optical coherence tomography, and genetic testing were performed on a patient with a retinal cavernous hemangioma and a CCM. Our patient was heterozygous in the KRIT1/CCM1 gene for a frameshift mutation, c.1088delC. This would be predicted to result in premature protein termination. We have identified a novel mutation in the KRIT1/CCM1 gene in a patient with both CCM and retinal cavernous hemangioma. We hypothesize that the occurrence of retinal cavernous hemangiomas and CCMs is underlaid by a common mechanism present in the KRIT1/CCM1 gene.

Purpose

To report on the heterogeneity of monosomy 3 in a fine needle aspiration biopsy obtained transsclerally from choroidal melanoma for prognosis.

Methods

All clinical records for patients who had been diagnosed with choroidal melanoma and underwent iodine-125 plaque brachytherapy with intraoperative transscleral fine needle aspiration biopsy from January 2005 to August 20, 2011, and who had a positive result for monosomy 3 according to fluorescence in situ hybridization as reported by clinical cytogenetics testing were collected. Patient age and sex, total number of cells evaluated and number of cells positive for monosomy 3, tumor size, and metastatic outcome were recorded for each patient.

Results

A positive result for monosomy 3 was reported in 93 patients who underwent transscleral fine needle aspiration biopsy. Two patients were lost to follow-up immediately post-operatively, and the remaining 91 patients were included in this study. The mean number of cells evaluated in the biopsy was 273 (range 28 to 520). The mean percentage of cells positive for monosomy 3 was 62.9% (range 4.7%-100%). The mean tumor height was 5.91 mm (range 1.99 to 10.85 mm). Larger tumors were associated with a higher percentage of cells positive for monosomy 3. During the average follow-up interval of 28.9 months (range 3-76 months), choroidal melanoma metastasis developed in 18 (20%) patients. Patients whose tumors had 1%-33% of cells positive for monosomy 3 had a significantly lower risk of metastasis-related death compared to patients whose tumors harbored a higher percentage of monosomy 3 (p = 0.04).

Conclusions

Cytogenetic heterogeneity of fluorescent in situ hybridization for monosomy 3 exists in a biopsy sample. Larger tumors were more likely to have a higher percentage of monosomy 3 positive cells in the sample. Furthermore, patients whose tumors had more than 33% of cells positive for monosomy 3 had a poorer prognosis than patients whose tumors had lower percentages of monosomy 3.

To determine if choroidal melanoma patients want cytogenetic prognostic information. Ninety-nine choroidal melanoma patients completed a questionnaire regarding their opinions about receiving prognostic information. The perceived usefulness of prognostic information was evaluated in patients who had undergone cytogenetic testing. Depressive symptoms, quality of life, and interest in supportive counseling during test receipt were assessed. Ninety-seven percent of respondents reported that they would have wanted prognostic information at the time of their treatment and 98% of respondents reported that supportive counseling should be offered when prognostic information is given. Patients who had received a more favorable prognostic result were more likely to endorse the usefulness of cytogenetic testing than were patients who had received a less favorable prognostic result. Psychological status did not vary significantly as a function of cytogenetic test result. Prognostic information was important to patients with choroidal melanoma, even in the absence of prophylactic measures which might improve prognosis.

INTRODUCTION:Uveal melanoma is a rare intraocular tumor with heterogeneous biological behavior, and additional noninvasive markers that may predict outcome are needed. Diffusion- and perfusion-weighted imaging may prove useful but have previously been limited in their ability to evaluate ocular tumors. Our purpose was to show the feasibility and potential value of a multiparametric (mp-) MRI protocol employing state of the art diffusion- and perfusion-weighted imaging techniques. METHODS:Sixteen patients with uveal melanoma were imaged with mp-MRI. Multishot readout-segmented echoplanar diffusion-weighted imaging, quantitative dynamic contrast-enhanced (DCE) MR perfusion imaging, and anatomic sequences were obtained. Regions of interest (ROIs) were drawn around tumors for calculation of apparent diffusion coefficient (ADC) and perfusion metrics (K (trans) , v e , k ep , and v p ). A generalized linear fit model was used to compare various MRI values with the American Joint Commission on Cancer (AJCC) tumor group and monosomy 3 status with significance set at P < 0.05. RESULTS:mp-MRI was performed successfully in all cases. MRI tumor height (mean [standard deviation]) was 6.5 mm (3.0). ROI volume was 278 mm(3) (222). ADC was 1.07 (0.27) × 10-3 mm(2)/s. DCE metrics were K (trans) 0.085/min (0.063), v e 0.060 (0.052), k ep 1.20/min (0.32), and v p 1.48 % (0.82). Patients with >33 % monosomy 3 had higher K (trans) and higher v e values than those with disomy 3 or ≤33 % monosomy (P < 0.01). There were no significant differences between ADC (P = 0.07), k ep (P = 0.37), and v p with respect to monosomy 3. CONCLUSION:mp-MRI for ocular tumor imaging using multishot EPI DWI and quantitative DCE perfusion is technically feasible. mp-MRI may help predict monosomy 3 in uveal melanoma.
