Summary
Retinoblastoma outcomes are worse in lower-income countries. Patients in lower and middle-income nations face higher metastasis-related mortality and local treatment failure rates compared to high-income nations.
Area of Science:
- Ophthalmology
- Oncology
- Global Health
Background:
- Retinoblastoma is the most common intraocular malignancy in children.
- Outcomes for retinoblastoma vary significantly worldwide, influenced by socioeconomic factors.
Purpose of the Study:
- To compare metastasis-related mortality, local treatment failure, and globe salvage rates for retinoblastoma across countries with differing national income levels.
- To investigate the impact of national income on retinoblastoma treatment outcomes.
Main Methods:
- An international, multicenter, registry-based retrospective case series involving 2190 patients from 18 ophthalmic oncology centers in 13 countries.
- Data from retinoblastoma patients (2001-2013) were analyzed, classifying countries as high-income (HICs), upper middle-income (UMICs), or lower middle-income (LMICs).
- Statistical analyses included Kaplan-Meier survival estimates and logistic/Cox regression models to assess associations between national income and outcomes.
Main Results:
- Patients in UMICs and LMICs were diagnosed at a later median age (20.0 months) compared to HICs (14.0 months).
- Metastasis-related mortality was substantially higher in UMICs (10.3-fold) and LMICs (9.3-fold) versus HICs.
- Local treatment failure rates were also significantly higher in UMICs (2.2-fold) and LMICs (1.6-fold) compared to HICs.
Conclusions:
- Lower national income levels are significantly associated with increased metastasis-related mortality and local treatment failure in retinoblastoma.
- Global disparities in healthcare resources and access contribute to poorer retinoblastoma outcomes in lower-income settings.
- Addressing socioeconomic factors is crucial for improving globe salvage and survival rates in retinoblastoma worldwide.

The Retinoblastoma Gene
4.5K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
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,...

Regression Toward the Mean
6.7K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
293
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Cancer Survival Analysis
557
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
