Summary
This study analyzed 500 childhood retinoblastoma (RB) cases in Mexico, finding high rates of advanced stages and varied treatments. Developing a national early detection program and standardized treatment protocol is crucial for improving outcomes in pediatric cancer.
Area of Science:
- Pediatric Ophthalmology
- Pediatric Oncology
- Cancer Epidemiology
Background:
- Retinoblastoma (RB) is a rare childhood cancer.
- Mexico may have a higher incidence of RB than global averages.
- Limited data exists on RB characteristics within Mexico.
Purpose of the Study:
- To present findings from a multicenter clinical survey of retinoblastoma in Mexico.
- To characterize the epidemiology and treatment of RB in a Mexican population.
Main Methods:
- Retrospective analysis of 500 RB cases over six years from 16 institutions.
- Variables included age, sex, eye involvement, treatment, and pathological stage.
- Overall survival data was collected.
Main Results:
- The study included 500 patients, with 72.8% presenting with unilateral retinoblastoma.
- Enucleation was the primary treatment (84.9%), with chemotherapy used in 74.4%.
- A significant proportion of cases were diagnosed at advanced stages (e.g., 52.8% Stage II, 18.0% Stage III, 11.4% Stage IV), with 89% disease-free survival at 73 months.
Conclusions:
- This is a pioneering multicenter study in Mexican pediatric ophthalmology and oncology.
- High rates of advanced-stage disease and treatment variability necessitate a cooperative approach.
- A national early detection program and standardized treatment protocol are essential for improving care for retinoblastoma patients.
