Global Retinoblastoma Study Group IMPORTANCE Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale.OBJECTIVES To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. DESIGN, SETTING, AND PARTICIPANTSA total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. MAIN OUTCOMES AND MEASURESAge at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. RESULTSThe cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low-and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 [95% CI,, and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 [95% CI,). CONCLUSIONS AND RELEVANCEThis study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs.

BackgroundThe travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.MethodsA cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries.ResultsCapture rate was 42.2% of expected patients from Africa and 108.8% from Europe. African patients were older (95% CI −12.4 to −5.4, p<0.001), had fewer cases of familial retinoblastoma (95% CI 2.0 to 5.3, p<0.001) and presented with more advanced disease (95% CI 6.0 to 9.8, p<0.001); 43.4% and 15.4% of Africans had extraocular retinoblastoma and distant metastasis at the time of diagnosis, respectively, compared to 2.9% and 1.0% of the Europeans. To reach a retinoblastoma centre, European patients travelled 421.8 km compared to Africans who travelled 185.7 km (p<0.001). On regression analysis, lower-national income level, African residence and older age (p<0.001), but not travel distance (p=0.19), were risk factors for advanced disease.ConclusionsFewer than half the expected number of patients with retinoblastoma presented to African referral centres in 2017, suggesting poor awareness or other barriers to access. Despite the relatively shorter distance travelled by African patients, they presented with later-stage disease. Health education about retinoblastoma is needed for carers and health workers in Africa in order to increase capture rate and promote early referral.

Objective: To assess the level of satisfaction of patients who access the Ophthalmic counselling services anchored by trained social workers of the University of Calabar Teaching Hospital, Calabar, NigeriaMethods: A cross-sectional study of serial consenting participants was done. Ethical approval was obtained from the University of Calabar Teaching hospitals’ ethics committee. Data was obtained using a semi-structured intervieweradministeredquestionnaire. Data were collated and analyzed using the SPSS for Windows (version 20, SPSS inc. Chicago, IL, USA). Modified Likert scale (very satisfied, satisfied and not satisfied) was used to rate the satisfaction level.Results: A total of 120 respondents met the inclusion criteria and were enrolled into the study. Majority of the respondents (60%) were male with an overall mean age of 45.32± 1.82. Over a quarter (28.3%) of the respondents were in the age bracket of 41-50. Glaucoma (48.3%) was the most common eye condition of the respondents. Seventy-five percent of the respondents were satisfied with the average time spent for the counselling services while 76.7% were satisfied with the overall ophthalmic counselling services they received with 46.7% believing that the service was provided by a social worker.Conclusion: Majority of the Patients were satisfied with the Ophthalmic counselling services mainly anchored by social workers. Training and retraining of allied support staff to render ophthalmic counselling services in order to ease the workload of the Ophthalmologist should be encouraged in resource-limited settings.Keywords: Patients satisfaction, ophthalmic counselling service, NigeriaFunding: None declared
