RESUMO

Objective: This paper observes the efficacy of chemotherapy combined with CD19 and CD20 monoclonal antibodies in clearing minimal residual disease (MRD) and bridging transplantation for refractory acute B-lymphoblastic leukemia (B-ALL) in children and reviews the literature. Methods: A 4-year-old boy diagnosed with B-ALL in our hospital was treated with the SCCLG-ALL-2016 protocol. MRD and gene quantification decreased after induction but remained persistently positive, with poor efficacy. After this patient received three cycles of consolidation chemotherapy combined with blinatumomab and rituximab, MRD and fusion gene quantification became negative, and he received allogeneic hematopoietic stem cell transplantation (allo-HSCT). Results: During the use of monoclonal antibodies, neurotoxicity, CRS, or other side effects did not occur. Before transplantation, MRD became negative, and the bone marrow had been in complete remission since transplantation (13 months). Conclusion: Chemotherapy combined with blinatumomab for refractory B-ALL in children can bring a better remission rate for patients and is a means of bridging transplantation. Nevertheless, sequential CD20 monoclonal antibody therapy is the first report , and no adverse effects were observed in our case. It is well tolerated and can be used as one of the treatments for refractory B-ALL.

RESUMO

Aims: Noninvasive tools for the prognosis of colorectal cancer (CRC) are in urgent need. Lipids and proteins have been studied in CRC several years, thus a prognostic indicator based on preoperative serum high-density lipoprotein cholesterol (HDL-C) and serum albumin (ALB) levels (HA score) in CRC patients and to compare the correlation with survival to that of the Glasgow prognostic score. Patient and methods: In the present study, the patient characteristics, clinicopathological factors, and the level of pre-treatment serum markers (HDL-C, ALB, CEA and CA19-9) were analyzed retrospectively in 248 patients with CRC. Results: In HA score, patients with reduced HDL-C and decreased ALB levels were allocated a score of 2, those with only one of these abnormalities were assign as score 1, and those with neither of these abnormalities were allocated a score of 0. The cut-off value of HDL-C and ALB were defined as median. Among these, the distribution of the HA score were 66 patients of score 2 (26.61%), 112 patients of score 1 (45.16%), and 70 patients of score 0(28.23%). The prognostic significance of the HA score was then determined by Univariate and multivariate cox hazards in CRC. Univariate analysis revealed that tumor invasion depth, lymph node metastasis, metastasis, TNM stage, CEA, CA19-9, HA score and GPS had a significant association with the OS and DFS of CRC, furthermore HA score (P<0.001, P<0.001) TNM stage(P<0.001, P<0.001) were retained as the prognostic factors that were associated with OS and DFS according to multivariate analyses. Conclusions: These results suggest that the overall survival (OS) and disease-free survival (DFS) were shorter in CRC patients with a high level of HA score. Thus, our study has proposed that the evaluation of preoperative serum HA score may be used to predict OS and DFS of CRC.
