ABSTRACT
Objective:To systematically evaluate the relationship between C-KIT gene mutation and the prognosis of childhood core-binding factor-related acute myeloid leukemia (CBF-AML).Methods:The PubMed database was searched with "KIT" "Acute Myeloid Leukemia" and "Children"; the Chinese Journal Full-text Database (CNKI), Chinese Biomedical Literature Database (CBM), VIP database and Wanfang database were also searched with "KIT" "Acute Myeloid Leukemia" and "Children", and the search time was from the establishment of the database to October 1, 2020. After strict screening, the literature was included in the analysis; according to the presence or absence of genetic changes, the included cases was divided into C-KIT mutation group and wild group, and the complete remission (CR) rate, event-free survival (EFS) rate, and overall survival (OS) rate of the two groups were analyzed.Results:Six articles were collected, including 4 articles in English and 2 articles in Chinese, with a total of 667 patients. There was a statistically significant difference in the EFS rate between the C-KIT mutation group and wild group in children with CBF-AML ( HR = 2.40, 95% CI 1.47-3.89, P = 0.001); there was no significant difference in the CR rate and OS rate ( OR = 0.93, 95% CI 0.48-1.80, P = 0.830; HR = 1.92, 95% CI 0.96-3.83, P = 0.065) between the two groups. Conclusions:C-KIT gene mutation may be a risk factor for poor prognosis in children with CBF-AML.
