    Abstract Background: Recent years have seen major changes in the diagnosis and treatment of solid intraocular tumors, mainly owing to an improved molecular biological understanding of their pathogenesis, new therapeutic approaches for the local treatment of tumors in children, and long-term follow-up observations in clinical trials.
    Methods: This review is based on pertinent publications retrieved by a selective search in PubMed.
    Results: Retinoblastoma is the most common type of primary intraocular tumor, with approximately 8000 new cases per year around the world, while malignant melanoma of the uvea is the most common primary intraocular tumor in adults, with approximately 7000 new cases per year around the world. Intraocular metastases of malignant tumors are ten times more common, in terms of incidence, than primary intraocular tumors and are therefore the most common intraocular tumors overall. Improved methods of intraocular biopsy, diagnostic imaging, and molecular genetic investigation have led to steady improvement in clinical and predictive diagnostic assessment. In the treatment of retinoblastoma, local techniques including brachytherapy and intra-arterial and intravitreal chemotherapy play a prominent role. Prognostic molecular-genetic testing now enables the highly selective identification of uveal melanomas that have a high potential to metastasize. Cutaneous and uveal melanomas differ both in their clinical behavior and in their basic biological features; to date, effective systemic treatment has been established for melanoma of the skin, but not for metastatic melanoma of the uvea. Intraocular metastases are common and often the initial manifestation of an extraocular tumor, particularly lung cancer.
    Conclusion: Modern diagnostic and therapeutic concepts for intraocular tumors can only be implemented through the close interdisciplinary collaboration of ophthal - mologists, oncologists, radiologists, radiotherapists, pathologists, and human geneticists.

    Abstract Heritable retinoblastoma can rarely be associated with a midline intracranial neuroblastic tumor, referred to as trilateral retinoblastoma. We present an unusual midline brain tumor in an infant that was identified as ectopic retinoblastoma by histopathology, DNA methylation analysis, and molecular genetic detection of biallelic somatic inactivation of the RB1 gene. There was no ocular involvement, and germline mutation was excluded. In this nonresectable tumor, treatment with systemic chemotherapy including high-dose therapy with autologous stem cell transplantation, but without definite local therapy, resulted in long-lasting tumor control.

    Abstract The rate-limiting step in retinoblastoma tumorigenesis is inactivation of both RB1 alleles, but it has remained unclear how this tumor acquires the additional changes that constitute a malignant phenotype. Zhang et al. characterized the genetic and epigenetic alterations in four retinoblastomas using whole-genome analysis techniques. In these samples, the retinoblastoma genome was found to be remarkably stable genetically, although recurrent mutations in BCOR were identified in 13% of patients. However, an approach that integrated the results of ChIP, methylation and expression analysis identified multiple, more frequent alterations of the epigenetic landscape. One of the leading genes on the list the authors obtained was SYK, a kinase epigenetically upregulated. Knockdown of this gene and exposure to small molecules inhibiting the kinase function stopped tumor growth in vitro and in vivo, thus offering a new therapeutic target for the treatment of retinoblastoma.

    Abstract Background: A small number of children with unilateral retinoblastoma later develop retinoblastoma in the contralateral eye (metachronous bilateral retinoblastoma).
    Methods: We analysed the clinical and genetic characteristics of children with sporadic unilateral retinoblastoma to identify risk factors for the development of metachronous bilateral disease.
    Results: Fifteen (3.1%) of 480 children with unilateral retinoblastoma later developed metachronous bilateral retinoblastoma (latency period  >30 days). The maximum latency period was 2.3 years after initial diagnosis. Nine (22.5%) of 40 children with a RB1 mutation detectable in blood developed metachronous bilateral disease while all 155 children proved to be without a germline RB1 mutation remained unilaterally affected. Clinically, the risk of developing metachronous bilateral retinoblastoma was higher for age at diagnosis ≤0.5 years compared with >0.5 years (19.6% vs 1.2%), and for multifocal compared with unifocal unilateral retinoblastoma (17.1% vs 2.2%).
    Conclusions: This study shows that an oncogenic RB1 mutation in the blood is a risk factor for metachronous bilateral retinoblastoma. Additional clinical risk factors for metachronous bilateral disease are diagnosis at young age (≤0.5 years) and multifocal unilateral retinoblastoma. Early genetic analysis may identify children at high risk of developing metachronous bilateral disease and may help to preserve vision using risk-adapted follow-up and early treatment.

    Abstract Purpose: In the last 10 years, intra-arterial chemotherapy (IAC) has been increasingly used in the clinical management of retinoblastoma. It is reported to provide tumor control even in advanced stage disease that might have previously required enucleation. In our clinical experience, there are three conditions that may impair the use of IAC: (1) significant collaterals to meningeal arteries, (2) technical failure of ophthalmic artery catheterization, or (3) retina blood supply from collaterals different to the ophthalmic artery. In the current study, we assessed the rate of IACs that could not be carried out in our institution due to these three reasons.
    Methods: All patients admitted for IAC in our hospital were retrospectively assessed by chart review. Non-application rate of IAC was assessed and classified according to the three abovementioned criteria. Complication rate of both finalized and interrupted interventions was recorded.
    Results: Ninety-eight patients (median age 21.4 months, range 5.3 months-10.5 years) were identified. IAC was performed in 69 (70.4%) patients and interrupted in 12 (12.2%) cases because of meningeal collaterals, in 8 (8.2%) because of technical failure to cannulate the ophthalmic artery, and in 9 (9.2%) because of alternative blood supply of the retina.
    Conclusion: The rather defensive approach that is pursued in our center resulted in an overall non-application rate of IAC around 30%. The relatively high probability of conditions that impair the use of IAC needs to be addressed adequately in the patient conversation prior to the procedure. Our rate of 8% of abstention from IAC due to technical limitations might be reduced by the application of more rigorous therapeutic approaches such as balloon occlusion of the distal internal carotid artery. More research is finally needed to determine if IAC can be safely performed in the presence of meningeal collaterals and via branches of the external carotid artery.
