Tandem autologous hematopoietic stem cell transplantation for embryonal brain tumors in infants and very young children.

Withdrawal of radiotherapy in patients with brain tumors under four years decreases chance for cure. AutoHSCT in a series of pilot studies demonstrated a potential to improve outcomes in these patients. The study included 50 patients with median age of 39 months (7-53).

[Combined therapy for children and adolescents with Ewing tumors (a 25-year experience)].

A total of 115 children (median age 10.5 years, range 2-17) with Ewing sarcoma family tumors (ESFT) received therapy in N.N.

[Effectiveness of high-dose polychemotherapy with autologous hemopoietic stem cell transplantation in the treatment for malignant tumors of the central nervous system in children and young adults].

A total of 40 patients (median age 6 years, range 1-28 years) with high-risk malignant brain tumors received a single (n = 35) or tandem (n = 5) high-dose chemotherapy (HDCT) with autologous hemopoietic stem cell transplantation (auto-HSCT). The 2-year OS and DFS are 52% and 47%, accordingly, with median follow-up of 24 (range 2-96) months. The patients without complete response at the time of auto-HSCT had worst prognosis with 53% DFS in patients with partial remission and 25% in patients with disease stabilization (p = 0.
