简要总结
The outcomes of children with lymphoblastic lymphoma (LBL) in China in the investigators' previous study were not unexpected. In this study, through further modification treatment protocols and strengthen domestic multicenter collaboration, the investigators try to improve survival for children with LBL when compared to the previous study.
详细描述
The treatment for LBL is an ALL (acute lymphoblastic leukemia)-based treatment. Additional, high dose L-asparaginase was reported to improve disease-free survival for patients with ALL. The event free survival (EFS) for pediatric LBL in most western countries have achieved 75% to 85%. However, the outcomes of children with LBL in China were not unexpected. In the previous study (CCCG-LBL-2010, 2009-2013), 96 patients with newly diagnosed LBL from 7 Chinese pediatric oncology centers were included. At a median follow-up of 21 months (range, 0.3~60.7months), the 2-year event free survival was 68±5% in all patients. Patients who had achieved complete remission on day 33 of induction had significantly better EFS than those who had not (77±6% v.s.17±10%, p<0.005). In the current trial, the investigators try to improve survival for children with LBL in China through further modification treatment protocols and strengthen domestic multicenter collaboration.
The BFM backbone will be used as the standard backbone therapy for this study. Three doses of daunorubicin are prescribed in induction compared with 4 doses in BFM studies. Cranial radiotherapy only saved for patients (>2 yrs) with CNS disease at presentation.
Complete remission (CR) is defined as at least 75% tumor regression, less than 5% BM (bone marrow)blasts, no CNS (central nervous system) disease, and disappearances of all evidence of disease from all sites for at least 4 weeks. Partial response (PR) is defined as > 50% tumor regression, and no new lesions.Response to treatment is evaluated on day 33 and day 64 of induction.Patients will be stratified into 3 risk groups.
Low risk group: patients (stage I or II) receive induction protocol I followed by the extracompartmental protocol M, and maintenance for up to a total therapy duration of 96 weeks. Totally, 3 doses of PEG-asparaginase (Pegylated-asparaginase) are applied in this group.
Intermediate risk group: patients (stage III or IV or receiving steroids within one week prior to the diagnosis) receive induction protocol I followed by the extracompartmental protocol M, reintensification protocol II, and maintenance for up to a total therapy duration of 104 weeks.Totally, 5 doses of PEG-asparaginase are applied in this group.
