RESUMEN
Purpose Molecular mechanisms of uveal melanoma development in association with high pigmentation are unclear. Tyrosinase Related Protein (TYRP1) is not only one of the important melanogenesis marker that contributes to melanin synthesis, but can also prevents the melanocyte death. The induction of melanogenesis leads to induction of HIF-1α which can affect the behavior of melanoma cells and its surrounding environment. The aim of our study was to determine the expression of TYRP1 and HIF-1α at the protein and RNA level and determine its prognostic significance. Methods In the present study, the expression of TYRP1 and HIF-1α was investigated on 61 formalin-fixed paraffin-embedded choroidal melanoma samples by immunohistochemistry. Fresh 50 samples were validated by real-time PCR. Results were correlated with clinicopathological parameters and KaplanMeier was performed to determine the prognostic significance. Results High immunoexpression of TYRP1 and HIF-1α was present in 61 and 54% of patients, respectively. Both TYRP1 and HIF-1α correlated well with high pigmentation and BAP1 (BRCA1 Associated Protein-1) loss (p < 0.05) at IHC level as well as transcriptional level. There was reduced metastatic free survival in patients with necrosis and this was statistically significant (p = 0.010). Conclusion Our findings indicate that TYRP1 can be used as a potential biomarker in the development of targeted therapy in UM. Further studies on melanogenesis markers associated with TYRP1 could provide us a better understanding in this field (AU)

BACKGROUND: The role of DNA damage response (DDR) proteins is poorly understood in uveal melanoma. ATR belongs to one of those proteins that induce DDR by arresting the cell cycle which leads to DNA repair. ATR is localized at position 23 on the same chromosome 3 where BAP1 is located at position 21.1 which is a known poor prognostic marker of UM. The aim of our study is to detect the expression of ATR at the protein and RNA levels and determine its prognostic significance. METHODS: Expression of nuclear ATR was investigated on sixty-nine UM patients. Formalin-fixed paraffin-embedded choroidal melanoma samples were taken to evaluate the expression of ATR. Fifty samples were also validated by real-time PCR. Results of both protein and mRNA were then correlated with clinicopathological parameters. To determine the prognostic significance, Kaplan-Meier and multivariate analyses were performed. RESULTS: Loss of ATR protein was seen in 72% cases which was statistically significant with epithelioid cell type (p = 0.005), tumor thickness (p = 0.016), mitotic figures (p = 0.001) and BAP1 loss (p < 0.001). At the transcriptional level loss of ATR was seen in 76% cases which were statistically significant with metastasis (p = 0.046), staging (0.044) and loss of BAP1 (p = 0.022). On multivariate analysis loss of ATR and tumor staging came out to be independent prognostic parameters. CONCLUSION: Our data suggest that ATR might serve as a potential prognostic marker in UM patients and could serve as a potential therapeutic target.

PURPOSE: Uveal melanoma (UM) is the most common intraocular cancer with a high mortality rate that requires new research in the field of prevention and treatment. c-REL is a member of the nuclear factor κB (NF-κB) transcription factor family and an emerging regulator of tumorigenesis. Therefore, the objective of the study is to evaluate the constitutive expression of c-REL in uveal melanoma patients and its prognostic significance. METHODS: Detection of c-REL expression was carried out by immunohistochemistry in all 75 patients, and qRT-PCR performed on 58 fresh cases of uveal melanoma along with IL-6 status. Immunoblot was performed to validate immunohistochemistry results. Expression of c-REL protein correlated with clinicopathological parameters and overall survival of patients. RESULTS: Immunohistochemistry results revealed nuclear expression of the c-REL protein (56%) in our cases. Out of 75 cases, 31 cases showed nuclear expression, and 11 cases had cytoplasmic expression. qRT-PCR showed upregulation of the REL gene in 56.89% cases at the transcriptional level. There was a statistically significant difference in the overall survival of patients with c-REL nuclear immunopositivity (p = 0.0048). On multivariate analysis, scleral invasion and c-REL nuclear expression found to be an independent prognostic factor (p < 0.05) CONCLUSIONS: To the best of our knowledge, this was the first study reporting the expression of the c-REL protein in uveal melanoma. Strong nuclear immunoexpression of c-Rel suggests NFκB pathway activation which might be involved in the progression of the disease. Differential expression of c-REL protein may be used as an attractive target for the development of anticancer strategies.

Purpose: Uveal melanoma, although a rare form of cancer, is the most common primary malignancy of the eye in adults. Nuclear factor-kapaB (NF-kapaB) is a transcription factor that transactivates genes involved in the regulation of cell growth, apoptosis, angiogenesis, and metastasis, but the molecular mechanisms that negatively regulate NF-kapaB activation are not fully understood. NF-kapaB can also be activated by DNA damage pathway through NEMO protein. Therefore, the objective of this study is to elucidate the role of NEMO/IKKgamma protein in uveal melanoma patients. Methods: Seventy-five formalin-fixed paraffin-embedded prospective tissues of uveal melanoma were included in the present study. These cases were reviewed and investigated for the expression of NEMO/IKKgamma protein by immunohistochemistry and validated by western blotting along with the qRT-PCR for mRNA expression. Expression levels were correlated with the clinicopathological parameters and patients outcome. Results: Immunohistochemistry showed cytoplasmic expression of NEMO/IKKgamma expression in only 22 out of 75 (29.33%) cases. This result was confirmed by western blotting, and correlated well with the immunohistochemical expression of NEMO/IKKgamma protein (48 kDa). In addition, downregulation of this gene was found in 87.93% of the cases when compared with the normal tissues. On statistical analysis, loss of NEMO/IKKgamma protein was correlated with neovascularization, high mitotic count, and presence of vascular loop (p < 0.05). There was less overall survival rate with low expression of NEMO/IKKgamma protein in patients with uveal melanoma. Conclusion: This was the first study suggesting the relevant role of NEMO/IKKgamma protein, and highlights the prognostic significance with outcome in uveal melanoma patients. This protein might be used as a screening biomarker in these patients after large-scale validation and translational studies

Purpose: Inconsistent data exist on long-term visual outcomes in survivors of retinoblastoma. No studies have been reported on role of ocular coherence tomography (OCT) in predicting visual acuity. We assessed visual acuity in patients with retinoblastoma treated at our center in whom affected eyes were preserved. Methods: Patients who had completed a 2-year follow-up and were more than 5 years of age at assessment were included. Clinical data were obtained from database and factors predicting visual acuity were analyzed. OCT was performed in these patients to assess central macular thickness (CMT). Results: Visual outcomes were assessed in 45 eyes of 43 patients, of which 38 (88 %) had bilateral retinoblastoma. The median age at diagnosis was 12 months. Sixty percent 27/45) had International classification of retinoblastoma group C or D disease with 40 % eyes showing macular lesions. The far visual acuity was better than 6/12 in 53 % (24/45), 6/12 to 6/60 in 40 % (18/45) and 6/60 in 7 % (6/ 60). Macular location and International classification of retinoblastoma predicted poor vision (p = 0.06 and 0.07, respectively). CMT was less than 200 lm in 3 of 36 eyes (8 %) and 1 eye showed epiretinal membrane. Radiotherapy was associated with foveal thinning (p = 0.003). Two of 3 eyes with foveal thinning had a vision of 6/60. Conclusions: Good visual outcomes were observed in half of retinoblastoma patients treated with eye preservation. Macular location and International classification of retinoblastoma group C and D predicted poor visual acuity, while previous radiotherapy predicted foveal thinning, which was associated with poor visual acuity (AU)

OBJECTIVE: The utility of impression cytology in ocular diseases has predominantly been restricted to the diagnosis of dry eye, limbal stem cell deficiency and conjunctival neoplasias. Its role in malignant eyelid lesions remains largely unexplored. Although scrape cytology is more popular for cutaneous lesions, impression cytology, being non-traumatic, has an advantage in small and delicate areas such as the eyelid. The present study has been designed to evaluate its role in the diagnosis and management of malignant eyelid lesions. METHODS: Thirty-two histopathologically proven malignant eyelid lesions diagnosed over a 2-year period, including 13 basal cell carcinomas, 11 sebaceous carcinomas, four squamous cell carcinomas, two malignant melanomas and two poorly differentiated carcinomas, formed the study group. RESULTS: The results of impression cytology were compared with those of histopathology in the study group and with an age- and sex-matched group of benign cases as controls. The sensitivity of impression cytology was 84% (27/32) for the diagnosis of malignancy and 28% (9/32) for categorization of the type of malignancy. CONCLUSIONS: Impression cytology is a simple, useful, non-invasive technique for the detection of malignant ulcerative eyelid lesions. It is especially useful as a follow-up technique for the detection of recurrences.

BACKGROUND: E-cadherin and ß-catenin are crucial components of the cell-cell adhesion complex. Their loss has often been associated with tumour metastasis and poor clinical outcome. Both loss of E-cadherin at the cell membrane and a stabilizing mutation in CTNNB1 (ß-catenin gene) have been associated with ovarian, colorectal, hepatocellular and nonmelanoma skin cancer, such as squamous and basal cell carcinomas. Absence of E-cadherin may be caused by promoter hypermethylation of the E-cadherin gene (CDH1). OBJECTIVES: To determine the role of E-cadherin promoter hypermethylation and CTNNB1 gene mutation in the aggressive behaviour of sebaceous gland carcinoma of the eyelid. METHODS: Thirty-six cases of sebaceous gland carcinoma were subjected to E-cadherin methylation-specific polymerase chain reaction and mutational analysis for the CTNNB1 gene. E-cadherin and ß-catenin staining was evaluated by immunohistochemistry. Results were correlated with the clinicopathological features of sebaceous gland carcinoma. RESULTS: nMethylation of the E-cadherin promoter region was detected in 72% of eyelid sebaceous gland carcinoma cases and loss of E-cadherin immunostaining in 83%. E-cadherin promoter hypermethylation showed a significant association with the loss of membranous E-cadherin (P = 0·038) and it was of borderline significance with reduced disease-free survival (P = 0·05). It was also found to be associated with advanced age (73%), tumour size ≥ 2 cm (77%), orbital invasion (83%), lymph node metastasis (60%), tumour recurrence (60%) and poor histological differentiation (90%). DNA sequencing revealed no stabilizing ß-catenin gene mutation in sebaceous gland carcinoma. Loss of membranous ß-catenin was observed in 61% cases, which associated significantly with both E-cadherin promoter methylation (P = 0·0262) and loss of E-cadherin membranous localization (P=0·0015). CONCLUSION: Epigenetic inactivation of the E-cadherin gene causes loss of membrane-bound E-cadherin and could contribute to the reduced disease-free survival in eyelid sebaceous gland carcinoma. Mutations in the ß-catenin gene do not seem to be involved in the pathogenesis of eyelid sebaceous gland carcinoma.

Retinoblastoma is the most common intraocular malignancy in children and one of the very few life-threatening ophthalmic conditions. Genetically, the disease may be heritable or non-heritable. It can have unilateral or bilateral involvement and can present either sporadically or with a positive family history. Leukocoria and strabismus are the most common presentations. Diagnosis is made by indirect ophthalmoscopy aided by imaging techniques. Multidisciplinary management is aimed at saving lives, salvaging the globe and maintaining good vision. The use of neoadjuvant chemotherapy and focal treatments, such as cryotherapy, laser photocoagulation, transpupillary thermotherapy, brachytherapy and periocular chemotherapy, form the mainstay of globe preserving treatment in retinoblastoma. In developing countries, retinoblastoma is unfortunately accompanied by a high mortality rate due to delayed diagnosis made at advanced stages of the disease. Early diagnosis and timely management are vital for a good prognosis.

PURPOSE: To study the effect of orbital tumors on visual functions and highlight the factors predictive of visual outcome after surgery. METHODS: A prospective interventional study compared visual function parameters and fundus changes, before and after surgery, in eyes having well-defined orbital tumors with the normal fellow eye. These included visual acuity (VA), refractive error, keratometry changes, color vision, Goldmann visual field (GVF), and visual evoked response (VER). RESULTS: In total 28 cases (age range 7-56 years), of which the majority of tumors were vascular (46%) and lacrimal (18%) in origin, had a mean VA of 0.54±0.33 in the affected eye, which improved postoperatively to 0.66±0.31 (P=0.002). The affected eye had a median refractive error of +0.00 DS (-2.00 to 5.13), which was significantly more hyperopic than the normal eye (median +0.00 DS; range -1.25 to +1.63 DS) and normalized postoperatively. Keratometry showed higher astigmatism in the involved eye (P=0.004). The fundus showed disc pallor, edema, and/or choroidal folds, of which disc edema resolved in all cases after surgery. In all, 40% of the affected eyes had a deficient color vision and this partially improved postoperatively (P=0.25). GVF had abnormalities in 10 cases, half of which normalized postoperatively (P=0.04). The VER of affected eyes had a mean amplitude of 8.91±4.59 µv and latency of 116.3±14.7 ms, with improvement after surgery (P=0.005 and 0.001, respectively). CONCLUSION: Orbital tumors adversely affected visual functions. The presenting acuity depended on disc changes, color vision abnormalities, and prolonged VER latency. The postoperative VA depended on VA at presentation, amount of proptosis, degree of hyperopia, and clinically significant VER abnormalities.
