Retinoblastoma: An update on genetic origin, classification, conventional to next-generation treatment strategies. Heliyon 2024; 10:e32844. [PMID: 38975183 PMCID: PMC11226919 DOI: 10.1016/j.heliyon.2024.e32844] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 05/23/2024] [Accepted: 06/10/2024] [Indexed: 07/09/2024] Open
Abstract
The most prevalent paediatric vision-threatening medical condition, retinoblastoma (RB), has been a global concern for a long time. Several conventional therapies, such as systemic chemotherapy and focal therapy, have been used for curative purposes; however, the search for tumour eradication with the least impact on surrounding tissues is still ongoing. This review focuses on the genetic origin, classification, conventional treatment modalities, and their combination with nano-scale delivery systems for active tumour targeting. In addition, the review also delves into ongoing clinical trials and patents, as well as emerging therapies such as gene therapy and immunotherapy for the treatment of RB. Understanding the role of genetics in the development of RB has refined its treatment strategy according to the genetic type. New approaches such as nanostructured drug delivery systems, galenic preparations, nutlin-3a, histone deacetylase inhibitors, N-MYC inhibitors, pentoxifylline, immunotherapy, gene therapy, etc. discussed in this review, have the potential to circumvent the limitations of conventional therapies and improve treatment outcomes for RB. In summary, this review highlights the importance and need for novel approaches as alternative therapies that would ultimately displace the shortcomings associated with conventional therapies and reduce the enucleation rate, thereby preserving global vision in the affected paediatric population.

Zhang WX, Shimony JS, Lueder GT, Reynolds MM. Apparent Diffusion Coefficient (ADC) Differentiates Retinoblastoma from Coats Disease on MRI. Am J Ophthalmol 2024; 267:8-12. [PMID: 38866359 DOI: 10.1016/j.ajo.2024.05.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 05/16/2024] [Accepted: 05/17/2024] [Indexed: 06/14/2024]
Abstract
PURPOSE Coats' disease can be difficult to differentiate from retinoblastoma. While MR imaging of retinoblastoma and Coats' disease have been examined for differentiating features such as eye size, vitreous seeding, and shape of retinal detachment, there is a lack of data on apparent diffusion coefficient (ADC). ADC is a measure of the diffusion (of water molecules) within tissue, and is commonly clinically calculated using MRI. DESIGN Retrospective cross-sectional study. METHODS Patient or study population: Children < 18 diagnosed with Coats disease or Retinoblastoma between January 1, 2018 and January 8, 2022 who had MRI imaging that was reviewable. MAIN OUTCOME MEASURE Apparent diffusion coefficient (ADC) of the intraocular lesion. Retrospective brain MRIs were obtained from records of 5 eyes of 5 Coats' patients and 29 eyes of 23 patients with retinoblastoma. All MRIs were obtained prior to treatment. The eyedropper tool in Epic's default viewer (Ambra DICOM) was used to measure the ADC of five to eight randomly sampled points within the eye lesions seen on MRI. Average ADC was calculated for each affected eye. Internal reliability was confirmed by re-measuring mean ADC for a random sample of patients masked to their diagnosis and prior measurements. T-test was used to determine if ADC values differ between groups. RESULTS The mean ADC for retinoblastoma patients (442 +/- 210 mm2/s) differed significantly from the mean for Coats' patients (1364 +/- 309 mm2/s), (P < .001). T-test between baseline and repeat measurements was not significantly different. Since ADC values can differ between different scanners and DW MRI pulse sequences, an ADC threshold may be difficult to generalize across institutes, in our data set a threshold of 900 mm2/s was useful in separating the two diagnoses with a high degree of accuracy. CONCLUSIONS Clinical features of retinoblastoma and Coats' disease often resemble each other and can lead to misdiagnosis. Since ADCs are derived from diffusion-weighted MRI as an objective parameter, it has the potential to aid in establishing or confirming the diagnosis when retinoblastoma and/or Coats' disease are suspected.

Abstract
Orbital pathologies can be broadly classified as ocular, extra-ocular soft-tissue (non-neoplastic and neoplastic), osseous, and traumatic. In part 1 of this orbital series, the authors will discuss the differential diagnosis and key imaging features of pediatric ocular pathologies. These include congenital and developmental lesions (microphthalmos, anophthalmos, persistent fetal vasculature, coloboma, morning glory disc anomaly, retinopathy of prematurity, Coats disease), optic disc drusen, infective and inflammatory lesions (uveitis, toxocariasis, toxoplasmosis), and ocular neoplasms (retinoblastoma, retinal hamartoma, choroidal melanoma, choroidal nevus). This pictorial review provides a practical approach to the imaging work-up of these anomalies with a focus on ocular US as the first imaging modality and additional use of CT and/or MRI for the evaluation of intracranial abnormalities. The characteristic imaging features of the non-neoplastic mimics of retinoblastoma, such as persistent fetal vasculature and Coats disease, are also highlighted.

Abstract
Retinoblastoma is the most common cause of all intraocular pediatric malignancies. It is caused by the loss of RB1 tumor suppressor gene function, although some tumors occur due to MYCN oncogene amplification with normal RB1 genes. Nearly half of all retinoblastomas occur due to a hereditary germline RB1 pathogenic variant, most of which manifest with bilateral tumors. This germline RB1 mutation also predisposes to intracranial midline embryonal tumors. Accurate staging of retinoblastoma is crucial in providing optimal vision-, eye-, and life-saving treatment. The AJCC Cancer Staging Manual has undergone significant changes, resulting in a universally accepted system with a multidisciplinary approach for managing retinoblastoma. The authors discuss the role of MRI and other diagnostic imaging techniques in the pretreatment assessment and staging of retinoblastoma. A thorough overview of the prevailing imaging standards and evidence-based perspectives on the benefits and drawbacks of these techniques is provided. Published under a CC BY 4.0 license.

Abstract
BACKGROUND AND PURPOSE Non-EPI-based DWI has shown better performance in head and neck pathologies owing to lesser susceptibility artifacts compared with EPI-DWI. However, only sporadic studies have investigated the feasibility of non-EPI-based DWI in retinoblastoma (RB). We qualitatively and quantitively compared EPI-DWI and HASTE-DWI in RB and correlated the tumor ADC values obtained from these 2 techniques with histopathologic markers. MATERIALS AND METHODS Twenty-one treatment-naive patients with RB underwent 1.5T orbital MR imaging. EPI-DWI and HASTE-DWI were acquired at 3 b-values (0, 500, and 1000 s/mm2). All patients subsequently underwent surgical enucleation. For qualitative image assessment, scoring of overall image quality, artifacts, tumor sharpness, and tumor conspicuity was done by using a 5-point Likert scale. Quantitative assessment included calculations of SNR, contrast-to-noise ratio (CNR), geometric distortion, and ADC. Qualitative scores were compared by using the Wilcoxon signed-rank test, and quantitative parameters were analyzed with a t test. RESULTS All 21 patients had unilateral RB; 15 were male and 6 were female with a median age of 36 months (range, 9-72 months). On histopathology, patients had either poorly differentiated (n = 13/21) or moderately differentiated (n = 8/21) RB. Other poor prognostic markers evaluated were optic nerve invasion (n = 10/21), choroidal invasion (n = 12/21), and anterior eye segment enhancement on MRI (n = 6/21). HASTE-DWI demonstrated higher image quality scores than EPI-DWI (P < .01), except for tumor conspicuity score, which was higher for EPI-DWI (P < .001). HASTE-DWI showed lower SNR, CNR, and geometric distortion than EPI-DWI (P < .001). The average acquisition times of EPI-DWI and HASTE-DWI were ∼1 and 14 minutes, respectively. The mean tumor ADC value on EPI-DWI was 0.62 ± 0.14 × 10-3 mm2/s and on HASTE-DWI was 0.83 ± 0.17 × 10-3 mm2/s. A significant correlation between EPI-DWI and HASTE-DWI ADC values (r = 0.8; P = .01) was found. Lower ADC values were found in tumors with poor prognostic markers, but none reached a statistically significant difference. CONCLUSIONS HASTE-DWI shows improved overall image quality; however, it lacks in terms of tumor conspicuity, SNR, CNR, and longer acquisition time compared with EPI-DWI. ADC values derived from HASTE-DWI show no advantage over EPI-DWI in correlation with histopathologic prognostic markers.

Abstract
The methyltransferase 14, N6-adenosine-methyltransferase subunit (METTL14) and Cyclin-dependent kinase inhibitor 2A (CDKN2A) have been identified as involved in the regulation of various cancer progression, while their mechanism and regulatory effect in retinoblastoma (RB) is still unclear. Cell colony formation, CCK-8 as well as Western blotting were used to evaluate the proliferation, apoptosis as well as p53 protein level of RB cell line. The METTL14 and CDKN2A levels were detected by qRT-PCR or Western blotting when METTL14 was up-regulated or CDKN2A was down-regulated. MeRIP and Pearson analysis were performed to confirm the regulatory relationship between METTL14 among CDKN2A. We found that the levels of CDKN2A and METTL14 were abundant in RB samples, as well as RB cells. METTL14 enhances N6-methyladenosine (m6A) modification of CDKN2A to upregulate its mRNA and protein levels. The proliferation of RB cells can be inhibited by silencing CDKN2A, which promotes apoptosis and p53 protein level. Furthermore, high-expression of METTL14 eliminated the anti-tumor effect of CDKN2A silencing in RB progression in vitro. CDKN2A is mediated by METTL14-m6A modified and restrains p53 pathway activation to accelerate the malignancy of RB. This points to the METTL14-m6A-CDKN2A-p53 pathway axis as a possible prospective target for the future RB treatment.

Abstract
Retinoblastoma (RB) is a pernicious tumor originating from photoreceptor precursor cells that often endangers the lives of children. The purpose of our study was to further investigate the influence of cathepsin B (CTSB) nuclear translocation on RB cell death. Y79 cells were injected into the vitreous cavity of nude mice at a dose of 4 µL/mouse to establish an animal model of RB. Real-time quantitative polymerase chain reaction (RT-qPCR), Western blot analysis, a comet assay, a Cell Counting Kit-8 (CCK-8) assay and flow cytometry were used to measure the levels of the interrelated genes and proteins and to evaluate alterations in autophagy, apoptosis, proliferation, DNA damage and cell cycle arrest. CTSB was found to be expressed at low levels in RB animal model samples and RB cell lines. Functionally, CTSB nuclear translocation promoted DNA damage, cell cycle arrest, ferroptosis and autophagy in Y79 cells and inhibited their proliferation. Downstream mechanistic studies showed that nuclear translocation of CTSB facilitates DNA damage and cell cycle arrest in RB cells by inhibiting breast cancer 1 protein (BRCA1) expression and also activates the signal transducer and activator of transcription 3/stimulator of interferon response cGAMP interactor 1 (STAT3/STING1) pathway to induce lysosomal stress, leading to ferroptosis and autophagy in Y79 cells and alleviating RB. Nuclear translocation of CTSB facilitates DNA damage and cell cycle arrest in RB cells by inhibiting BRCA1 expression and activating the STAT3/STING1 pathway and induces lysosomal stress, which eventually leads to ferroptosis and autophagy and mitigates RB.

Abstract
BACKGROUND AND PURPOSE Retinoblastoma is the most common primary intraocular tumor in childhood. Intra-arterial chemotherapy is becoming the standard of care for both first-line and rescue therapy, thus improving survival rates and decreasing the adverse effects of retinoblastoma treatment. Cardiorespiratory adverse events during general anesthesia for intra-arterial chemotherapy, including decreased lung compliance and bradycardia, have been described, but data regarding associated factors are still lacking. We aimed to assess the characteristics of patients and procedures associated with cardiorespiratory events during intra-arterial chemotherapy. MATERIALS AND METHODS We performed a prospective monocenter observational study in children diagnosed with retinoblastoma undergoing intra-arterial chemotherapy under general anesthesia. The occurrence of cardiorespiratory events was registered. We also assessed clinical and procedural characteristics potentially associated with these events. RESULTS A cardiorespiratory event was observed in 22 (12.5%) procedures, predominantly a decrease in tidal volume observed in 16 (9%) procedures. The median age was lower in the procedures with a cardiorespiratory event (20.43 [SD, 11.76] months versus 30.11 [SD, 24.17] months) (P < .05). Other variables such as bilateral disease or a previous intra-arterial chemotherapy treatment were not associated with the occurrence of a cardiorespiratory event. CONCLUSIONS In children undergoing intra-arterial chemotherapy for retinoblastoma treatment, cardiorespiratory events were observed in 12.5% of procedures. Lower age was associated with this complication. Although predominantly mild, these events should have prompt diagnosis and treatment to prevent further deterioration and worse outcomes.

Abstract
Imaging plays a crucial role in evaluating paediatric patients with non-traumatic head and neck lesions in an emergency setting because clinical manifestations of these entities can overlap. For this reason, radiologists must be familiar with the clinical and imaging findings of prevalent paediatric head and neck emergencies. In this review, we present techniques and imaging clues for common complications of pathological processes in the paediatric head and neck, with a focus on the clinical scenario as a starting point for the radiologic approach.

Abstract
Pediatric orbital masses are not common but encompass a wide spectrum of benign and malignant entities that range from developmental anomalies to primary and secondary orbital malignancies and metastatic disease. Certain orbital tumors are unique to pediatric patients, such as retinoblastoma and neuroblastoma. Clinical symptoms and signs are often insufficient to differentiate between orbital lesions, and imaging is essential for narrowing the diagnostic considerations and determining the most appropriate management strategy. MRI is the primary imaging modality for evaluating orbital masses in children, with US and CT playing complementary roles. The authors review a spectrum of masses and tumor mimics that affect the pediatric globe and orbit. The shared and differentiating characteristics of pediatric orbital lesions are reviewed. Emphasis is placed on utilizing an orbital compartment-based approach to narrow the differential diagnosis. By using this organizational scheme, the authors describe intraocular processes (retinoblastoma, persistent fetal vasculature, and Coats disease), intraconal lesions (lymphatic malformation, schwannoma, optic nerve sheath meningioma, and optic pathway glioma), extraconal lesions (infantile hemangioma, rhabdomyosarcoma, idiopathic orbital inflammation, lymphoma, venous varix, plexiform neurofibroma, and pleomorphic adenoma of the lacrimal gland), and lesions involving the bony orbit (dermoid cyst, metastatic neuroblastoma, and Langerhans cell histiocytosis). The authors describe the basic management of each entity. Orbital infections and traumatic lesions are beyond the scope of this article. ©RSNA, 2022.

Abstract
In this article we focus on a systematic approach to assess common orbital lesions on magnetic resonance imaging (MRI). The identification of the probable compartment or structure of origin helps narrow the differential diagnosis of a lesion. Analyzing the morphology, appearance, and signal intensity on various sequences, the pattern, and degree of contrast enhancement are key to characterize lesions on MRI. Imaging features suggesting cellularity and vascularity can also be determined to help plan for biopsy or surgery of these lesions. MRI can also distinguish active from chronic disease in certain pathologies and aids in selecting appropriate medical management. MRI may thus serve as a diagnostic tool and help in guiding therapeutic strategies and posttreatment follow-up.

Abstract
Retinoblastoma is the most frequent ocular malignancy in the pediatric population and intra-arterial chemotherapy has emerged as the first-line treatment of this entity with cure rates ranging from 33-100%, depending on the severity of the disease. We present the case of an advanced retinoblastoma in a pediatric patient who underwent intra-arterial chemotherapy through a contralateral route due to unsuccessful catheterization of the ophthalmic artery. The patient was diagnosed with a class D retinoblastoma which underwent the catheterization of the ophthalmic artery through the contralateral internal carotid and through the anterior communicating artery. In this case, intra-arterial chemotherapy administration was successfully delivered without complications. Contralateral routes for intra-arterial chemotherapy are safe and allow adequate penetration of the chemotherapeutic drugs in cases where a well-developed anterior communicating artery is present.
