Survival of pediatric patients with ependymoma in a tertiary cancer center in Rio de Janeiro, Brazil.

Introduction: Ependymoma is the third most frequent central malignant nervous system tumor in the pediatric age group. There is scarce data in the literature on survival of these patients, especially in upper and lower middle-income countries. We aimed to describe the clinical and demographic characteristics, treatment, and outcome of pediatric patients with ependymoma admitted to a public cancer hospital.

Epidemiological characteristics and survival outcomes of children with medulloblastoma treated at the National Cancer Institute (INCA) in Rio de Janeiro, Brazil.

Background: Medulloblastoma (MB),the most common malignant brain tumor of childhood has survival outcomes exceeding 80% for standard-risk and 60% for high-risk patients in high-income countries (HICs). These results have not been replicated in low- and middle-income countries (LMICs), where 80% of children with cancer live.

Methods: This is a retrospective review of 114 children aged 3-18 years diagnosed with MB from 1997 to 2016 at National Cancer Institute (INCA).

Time to diagnosis of retinoblastoma in Latin America: A systematic review.

Retinoblastoma (RB) is the most common intraocular tumor of childhood. In low income countries, Time to diagnosis (TTD: interval between first symptom and diagnosis) has been associated with extraocular disease, metastasis and mortality. However, the relationship between TTD and prognosis is complex and not simply a linear correlation, particularly if TTD is <6 months.
