The purpose of this study is to investigate the expression and clinical significance of ALK gene rearrangement in pediatric extra-pulmonary IMT. A total of 50 pediatric extra-pulmonary IMT samples were collected and ALK gene rearrangement was detected by fluorescence in situ hybridization (FISH) technique. At the same time, the correlation between ALK rearrangement and clinical pathological features, treatment response was analyzed. The results showed that ALK gene rearrangement was detected in 14 patients (28%), indicating that ALK gene rearrangement may be an important molecular mechanism of pediatric extra-pulmonary IMT. There was no significant difference in clinical features such as patient age, primary lesion size, and multiple lesions proportion between ALK positive and negative groups. However, the positive group had better treatment results and is expected to become a therapeutic target for this disease. The results of this study suggest that ALK gene rearrangement is a potential molecular mechanism of pediatric extra-pulmonary IMT and may bring new breakthroughs to its precision treatment.精品文档---下载后可任意编辑Keywords: pediatric extra-pulmonary IMT; ALK gene rearrangement; FISH; treatment strategy.
