  • Clinical pathology analysis of 30 patients with mushroom shaped uveal melanoma

    ObjectiveTo analyze the clinical pathological features of mushroom shaped uveal melanoma.MethodsRetrospective clinical study. From June 2001 to Aprilh 2013, pathological sections from 102 eyes of 102 patients with uveal melanoma diagnosed in Beijing Tongren Eye Center were included in the study. The sections were divided into group A (mushroom shaped uveal melanoma, 30 eyes) and group B (flat, hemisperical and spherical uveal melanoma, 72 eyes). The height-to-base ratio was calculated. The tumors size was divided into small, medium and large according to the standards of American Multicentre Study of Ocular Melanoma. The tumor cell type was divided into spindle, epithelioid, mixed and others by Improved Callender taxonomy. Motic Med 6.0 software was used to collect and measure the images. The retinal thinning rate of group A and B was compared by χ2 test.ResultsIn group A, large size in 19 eyes (63.3%), medium size in 11 eyes (36.7%). In group B, large size in 49 eyes (68.1%), medium size in 16 eyes (22.%), small size in 7 eyes (9.7%). In group A and B, the average tumor base diameter were 14.2±5.1 mm and 18.7±6.4 mm, respectively; the average tumor height were 10.0±2.1 mm and 7.6±3.9, respectively; the height-to-base ratio were 0.77±0.29 and 0.44±0.28, respectively. In group A, spindle type in 24 eyes (80.0%), epithelioid type in 1 eye (3.3%), mixed type in 5 eyes (16.7%). In group B, spindle type in 52 eyes (72.2%), epithelioid type in 5 eyes (6.9%), mixed type in 11 eyes (15.3%), and others in 4 eyes (5.6%). The proportion of retinal thinning were 73.3% (22 eyes) and 29.2% (21 eyes) in group A and B, respectively. The difference in the proportion of retinal thinning between group A and B was significant (χ2=16.94, P=0.000).ConclusionThe height of the tumor increased rapidly and the retinal thinning rate is high in mushroom shaped uveal melanoma.

  • Relationship of the gene of multidrug and drug resistance and the patients′prognosis in uveal melanoma

    Objective To probe the relationship between the patients′prognosis and the gene of multidrugs and drug resistance in uveal melanoma.Methods The gene expression of cyclin D1, epithelial growth factor receptor (EGFR), non-metastasis gene 23 (nm 23), P glucose protein (P-gp ) , multidrug resistance relation protein (MRP) and lung resistance protein (LRP) expression in 96 cases of uveal melanoma were detected by depigment immunohistochemistry. The patients with complete anamnesis data were observed continuously, and the follow-up results were classified. Results Among the 96 cases of uveal melanoma, the epithelioid cell type was in 21, the mixed cell type in 56, and the spindle cell type in 19 ; including 76 at intraocular stage and 20 at extraocular stage. As the level of metastasis suppress gene nm 23 expression decreased and the level of cyclin D1 and EGFR expression increased, the expression level of drug resistance genes increased. The levels of LRP and MRP had negative correlation to the expressions of nm 23 and postive correlation to the expressions of nm 23, Cyclin D1 and EGFR. In 58 patients′who were observed continuously, 19 died in 5 years and 26 survived over 5 years.Conclusion There are significant as sociation between patients′prognosis and multidrug and drug resistance gene in uveal melanoma.(Chin J Ocul Fundus Dis,2003,19:1-4)

  • 葡萄膜黑色素瘤抗血管生成靶向治疗的研究进展

    放射治疗、手术切除、经瞳孔温热疗法、巩膜敷贴治疗、化学药物治疗、免疫治疗等单独或联合应用对改善葡萄膜黑色素瘤(UM)患者生存率无明显差异。抗血管内皮生长因子(VEGF)抑制剂等抗血管生成靶向治疗与化学药物治疗、放射治疗等联合应用可明显提高疗效。但单独使用抗VEGF治疗UM效果并不理想, 而且还存在VEGF抑制剂导致肿瘤形成和转移播散的风险。虽然UM的抗血管生成靶向治疗取得了一些进展, 但是离真正的临床应用还有相当长的距离。需要进一步加强对UM的发病机制研究, 特别是UM新生血管发生发展机制方面的研究, 探索可能的干预靶点; 同时加强UM的转化医学研究, 筛选靶向治疗UM的新药物、新方法。

  • Clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma

    Objective To observe the clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma. Methods Thirty-six uveal metastatic carcinoma patients (43 eyes) were enrolled in this study. The patients included 21 males and 15 females. The patientsprime; ages ranged from 28 to 71 years, with a mean age of (47.3plusmn;10.2) years. Seven patients had bilateral carcinoma and 29 patients had unilateral carcinoma. There were 30 patients with lung cancer, three patients with breast cancer, one patient with gastric cancer and two patients without primary tumors. There were 20 patients with known primary cancer, 16 patients visited the Department of Ophthalmology first. All the patients were examined documenting visual acuity, intraocular pressure, slit-lamp microscopy and mydriatic fundus examination. Meanwhile, 22 patients (26 eyes) were examined using B-type ultrasound and/or color Doppler flow imaging (CDFI). Twelve patients (12 eyes) were examined using fundus fluorescein angiography (FFA) and/or indocyanine green angiography (ICGA). Seventeen patients (22 eyes) were examined using MRI and/or CT. The clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma patients were observed. Results Among 43 eyes, four lesions were in the iris, three lesions in the ciliary body and 32 lesions were in the choroid. Fundus examination showed an isolated mass in 26 eyes and more than two masses in nine eyes. Metastatic tumors of the iris and ciliary body often showed irregular cauliflower-like mass with gray-white or meat-red color and abundant vessels. The choroidal metastasis usually demonstrated flat rounded or irregular intraocular masses with gray-yellow or gray-white color in the posterior pole. B-type ultrasound showed ill-defined, flat, and irregular-shaped masses with uneven internal reflectivity. CDFI showed rich blood flow within the tumor. FFA and (or) ICGA showed pinpoint and mottled leaks against hyperfluorescence background. MRI revealed low or middle signal using T1WI and low signal intensity using T2WI. Conclusions The uveal metastatic carcinoma usually occurs in one eye with an isolated mass. Most of them show a flat gray-yellow mass in posterior choroids and have the primary cancer sites of the lung. FFA and/or ICGA show pinpoint and mottled leaks against hyperfluorescence background. B-type ultrasound and (or) CDFI show ill-defined, flat, and irregular-shaped mass with rich blood flow within the tumor. MRI reveals low signal intensity on T2WI.

  • Progress in immunotherapy for uveal melanoma

    Once uveal melanoma (UM) has distant metastasis, the median survival time of the patient is less than 12 months. There is currently a lack of standard treatment for metastatic UM. In recent years, immunotherapy is splendid in the field of oncology. Immune checkpoint therapy, cancer vaccine therapy and T cell adoptive therapy have been applied to UM therapy. However, most of the clinical effects are limited and the survival benefit is not high. The recent early research results of the new immunotherapeutic drug IMCgp100 are encouraging.

  • Clinical features of uveal metastases from lung carcinoma

    ObjectiveTo observe the clinical features of uveal metastases from lung carcinoma.MethodsA retrospective case study. From 1983 to 2014, 14 patients with uveal metastases of lung cancer confirmed by ocular examination in Peking Union Medical College Hospital were included in the study. Among them, 7 were male, 7 were female; 11 were monocular and 3 were binocular. The mean age was 54.5±9.6 years. Pathologic examination showed primary bronchial lung cancer, including 13 patients of non-small cell lung cancer (10, 2 and 1 patients of lung adenocarcinoma, squamous cell carcinoma and adenosquamous cell carcinoma, respectively) and 1 patient of small cell lung cancer. Four patients (28.6%) were diagnosed with lung cancer before ophthalmology consultation, and 10 patients (71.4%) were first diagnosed with ophthalmology due to ocular symptoms. The duration from ocular symptoms to lung cancer diagnosis was 1 week to 6 months. The course from diagnosis of lung cancer to ophthalmological consultation was ranged from 10 to 60 months, and the average course was 29.5±19.0 months. There were 7, 4 and 3 patients with impaired vision, occlusion of visual objects and deformation of visual objects, respectively. All patients underwent visual acuity, slit lamp microscope, B-mode ultrasound and UBM examinations. FFA was performed in 8 eyes, and 2 eyes were examined for ICGA. Orbital MRI was performed in 5 patients. Vitreoretinal surgery was performed on 1 eye. The clinical characteristics of the patients were analyzed and observed.ResultsIn 17 eyes, there were 2 eyes with visual acuity of light perception, 3 eyes of hand movement to counting finger before the eyes, 5 eyes of 0.1-0.3, 4 eyes of 0.4-0.6, 3 eyes of greater than 0.8. Metastatic cancer was located in iris in 1 eye, it presents as a red mass with irregular shape on the surface, which is full of small nourishing blood vessels. Metastatic cancer were located in choroid in 16 eyes, they presented yellowish-white or grayish-yellow lumps under the posterior pole or equatorial retina, including 14 eyes with a single lesion and 2 eyes with 2 lesions, with retinal detachment in 8 eyes and increased intraocular pressure in 5 eyes. B-mode ultrasonography showed posterior polar flat or surface irregular wavy intraocular space occupying lesions with localized or extensive retinal detachment. FFA and ICGA showed the focal, apical and patchy fluorescence of the tumor. MRI showed that T1WI medium and high signal consistent with the vitreous body, while T2WI showed low signal.ConclusionsUveal metastatic may be the first manifestation of lung cancer, and visual impairment, part of solid mass lesions with fundus flattening may be accompanied by secondary glaucoma and retinal detachment as the main clinical manifestations. Most of the metastatic sites are located in choroid, which is more common in single eye and single lesion. Adenocarcinoma is the most common type of uveal metastasis in non-small cell lung cancer.

  • The clinical features of primary uveal lymphoma of four cases

    ObjectiveTo investigate the clinical, ophthalmological and pathological features of primary uveal lymphoma.MethodsRetrospective clinical study. From 2012 to 2018 in Beijing Tongren Eye Cener, 4 cases and 4 eyes of patients with primary uveal lymphoma were included in the study. Among them, 3 cases were male and 1 case was female. The average age was (54 ± 13.58) years old. The average time from initial diagnosis to pathological diagnosis was (18.50 ± 9.29) months. 3 cases were enucleated and 1 case was biopsied. Extranodal marginal zone lymphoma (EMZL) of the mucosa associated lymphoid tissue (MALT) was confirmed by pathological examination. BCVA, fundus color photography, color Doppler ultrasound and orbital MRI were performed in all eyes. UBM, OCT, FFA and ICGA were performed in 2 eyes, 3 eyes, 3 eyes and 2 eyes respectively. The clinical, imaging and pathological changes were observed. Following up time was ≥ 6 months.ResultsAt the initial diagnosis, BCVA was 0.6, 0.02 and 0.01 in 1, 2 and 1 eye respectively. Choroid, ciliary body and iris were involved in 3 eyes, choroid in 1 eye. The fundus of the eyes showed infiltration of choroid in yellow and white color, and the lesions were beyond the vascular arch to the equator and peripheral areas. Color Doppler ultrasonography showed that choroidal diffuse thickening and extrascleral extension (ESE) which was the corresponding hypoechoic areas behind the sclera. Among them, ESE showed crescent thickening in 1 eye and nodular thickening in 3 eyes. UBM showed that the echo of ciliary body was thicken and the internal echo was decreased with the iris involved. OCT showed that RPE was wavy and local retinal neuroepithelial layer detached. FFA showed that the early lesions were mottled with strong and weak fluorescence, and the late fluorescence leakage. The posterior wall of the eyeball was thickened and enhanced in MRI.ConclusionThe clinical manifestations of uveal lymphoma are various, color Doppler ultrasound has characteristic manifestations and ESE of crescent or nodular thickening is valuable in diagnosis.
