Insights
A new Retinoblastoma (RB) registry in Ghana proved feasible and acceptable. This system enhances data collection for childhood eye cancer, improving treatment and global knowledge.
Area of Science:
- Ophthalmology
- Pediatric Oncology
- Health Informatics
Background:
- Retinoblastoma (RB) is the most common pediatric ocular tumor, disproportionately affecting low socio-demographic index regions.
- Establishing a Retinoblastoma registry is crucial for improving referral networks, treatment evaluation, and global knowledge sharing.
Purpose of the Study:
- To develop and assess the feasibility and acceptability of a Retinoblastoma registry in Ghana.
- To establish a centralized data collection system for pediatric eye cancer in Ghana.
Main Methods:
- An online REDCap database was utilized to create the Retinoblastoma registry.
- Data completeness, technical/operational feasibility, and user acceptability were evaluated.
- Registry leads at each treatment center were trained for data entry.
Main Results:
- The registry successfully captured socio-demographic, clinical, staging, and treatment outcome data.
- Technical and operational feasibility were confirmed with reliable infrastructure and offline caching.
- Average data entry time was 15 minutes with over 70% data quality; user interviews highlighted acceptability regarding completeness, timeliness, and relevance.
Conclusions:
- The Retinoblastoma registry demonstrated strong technical and operational feasibility in Ghana.
- High data quality and user acceptance support its integration into routine clinical practice.
- This registry is a vital tool for advancing pediatric eye cancer care and research.
Background:
Retinoblastoma (RB) is the most common ocular tumor in young children, originating from the developing retina, with the burden remaining higher in regions of low socio-demographic index. A registry of RB is essential for creating effective referral networks for evaluating treatment patterns and contributing to the global pool of knowledge.
Aim:
To develop an RB registry for Ghana and assess its feasibility and acceptability.
Methods:
An online REDCap (Research Electronic Data Capture) database was created as a registry of children diagnosed with RB in Ghana. Data completeness across core variables was analyzed and presented as a percentage. Technical, operational feasibility, and acceptability of the registry were assessed. Qualitative in-depth interviews were conducted with 2 users from each center to assess acceptability. At each treatment center, a registry lead was trained to enter data into the REDCap database.
Results:
Data were entered, aggregated, and stored in the REDCap database. Data captured included: socio-demographic and clinical information, clinical staging and systemic evaluations, histopathological risk assessment and staging, and final treatment outcomes. With reliable hardware performance, safe software features, and steady network connectivity backed by offline caching, the registry proved technically and operationally feasible. The average data entry time was 15 min, and the data quality was over 70%. Acceptability was emphasized in user interviews by themes of completeness and data quality, timeliness and workflow integration, and correctness and clinical relevance.
Conclusions:
The registry demonstrated strong technical and operational feasibility, with efficient workflows and reliable infrastructure. High data quality and user-validated acceptability underscore its integration into routine clinical practice.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
