retinoblastoma is a retinal malignant tumor that occurs in early childhood. the annual incidence of retinoblastoma is approximately one per 14 000 live births. 250 to 300 new cases are reported in the united states each year. it develops due to inactivation of both alleles of the retinoblastoma susceptibility (rb1) gene. all hereditary cases (55%) are with bilateral and multifocal lesions, but ...

purpose: to evaluate the results of combined chemotherapy and periocular carboplatin injection to control advanced intraocular retinoblastoma (rb). methods: in this prospective interventional case-series, we included 8 eyes of 8 patients with advanced intraocular rb (group c or d in international intraocular retinoblastoma classification, iirc). in these patients, periocular carboplatin was inj...

Retinoblastoma patients have cellular and humoral reactivity towards antigens expressed on retinoblastoma cells. We report the ultrastructural, cytogenetic, and immunologic features of four new retinoblastoma derived tissue culture cell lines. Studies with hybridoma produced monoclonal antibodies demonstrate that these lines share antigens with a previously described long-term allogeneic retino...

purpose : to evaluate the effectiveness of chemoreduction (crd) for globe saving in patients with intraocular retinoblastoma methods : in this interventional case series all patients with intraocular retinoblastoma were included and classified according to the international classification of retinoblastoma (icrb) from group a to e. six cycles of intravenous vincristine, etoposide and carboplati...

PURPOSE Perturbations in the retinoblastoma pathway are over-represented in advanced prostate cancer; retinoblastoma loss promotes bypass of first-line hormone therapy. Conversely, preliminary studies suggested that retinoblastoma-deficient tumors may become sensitized to a subset of DNA-damaging agents. Here, the molecular and in vivo consequence of retinoblastoma status was analyzed in models...

Background/Aim: We investigated the cytotoxic effects of plumbagin on metastatic retinoblastoma, using highly cell line Y79. Materials and Methods: Effect growth was assessed with water-soluble tetrazolium 1 (WST-1) proliferation assay automated hemocytometry trypan blue-exclusion assay. Cell death studied acridine orange/ethidium bromide live-dead annexin-V-fluorescein isothiocyanate/propidium...

Retinoblastoma is a pediatric eye tumor in which bi-allelic inactivation of the Retinoblastoma 1 (RB1) gene is the initiating genetic lesion. Although recently curative rates of retinoblastoma have increased, there are at this time no molecular targeted therapies available. This is, in part, due to the lack of highly penetrant and rapid retinoblastoma animal models that facilitate rapid identif...

Retinoblastoma is a rare childhood cancer of the retina that begins in utero and is diagnosed in the first years of life. The goals of retinoblastoma treatment are ocular salvage, vision preservation, and reduction of short- and long-term side effects without risking mortality because of tumor dissemination. To identify better chemotherapeutic combinations for the treatment of retinoblastoma, s...

Purpose To report the presenting signs of retinoblastoma in a large cohort patients who underwent orthoptic assessment at presentation. Methods A retrospective medical chart review was conducted on 131 with presented consecutively to single institution during 6-year period. The main outcome measure sign(s) disease. Results Of retinoblastoma, 88 unilateral disease and 43 bilateral (mean ages: 22...
