    Introduction: Cancer is the second leading cause of death among children aged 1 to 14 in the United States, and the fourth most common cause of death among adolescents aged 15 to 19. By 2024, 9,620 cases of cancer are expected to be diagnosed in children and 5,290 in adolescents. It is estimated that one in every 257 children and adolescents will be diagnosed with cancer before turning 20.

    Objective: to analyze the epidemiological profile of childhood cancer in follow-up in the Oncology Care Network of a state in southeastern Brazil.

    Methods: A descriptive observational study was undertaken, based on tumor registration forms from the Hospital Cancer Registries of the Childhood Cancer Care Network of a Brazilian state between 2007 and 2020. Descriptive and bivariate analyses were conducted in the R software.

    Results: The number of new cases of childhood cancer was 1,459, with 468 deaths in the series studied. The average age was 7.85 years; the majority were mixed race (53.32%), in the age range of 1-4 years (29.47%) (p = 0.008). Leukemia, followed by central nervous system tumors and lymphomas were the most frequent in males (p = 0.006) with a significant difference between age groups, with a higher occurrence between 5 and 9 years (p = 0.007). The present historical series showed a decreasing trend in the number of new cases (p<0.001). At the end of treatment, complete remission of the disease was observed in 30.57% of cases.

    Conclusion: Analysis of diagnostic groups by age group revealed unique patterns, with a higher prevalence of leukemia in boys and a higher occurrence of malignant bone tumors and carcinomas in adolescents aged 10-14 years, with a decreasing trend.
