Medulloblastoma; Survival; Pediatrics
Medulloblastoma (MB) is the most common malignant brain tumor of childhood, representing approximately 25% of all central nervous system (CNS) tumors that affect the pediatric population. The survival of children with medulloblastoma increases significantly when the combined treatment of surgery, radiotherapy and chemotherapy is used. The importance of the present study is the need to analyze the survival of patients diagnosed with medulloblastoma operated in an oncology referral center (INCA - Instituto Nacional de Câncer) compared to public and private hospitals that referred their patients for adjuvant treatment. (after surgery) to INCA. And thus, promote clarification on the treatment and follow-up of these patients in these different institutions, helping to direct public policies in the oncology area. The main objective of this study is to evaluate survival among patients with medulloblastoma operated at an oncology referral center and other hospitals. And it has as specific objectives: to compare the survival of patients with medulloblastoma in a reference center in relation to other hospitals and to characterize the oncology reference centers and to identify factors that may contribute to a better prognosis of patients operated with medulloblastoma in non-specialized centers. A retrospective cohort will be described, of both genders, with histopathological diagnosis of medulloblastoma, aged under 18 years, enrolled in the Pediatric Oncology sector of the National Cancer Institute (INCA). The cohort will describe the cases that occurred between 2010 and 2021 in order to study the disease-free and overall survival of these two two groups of patients.
