Correlation between DLK1 expression and the efficacy of imatinib adjuvant treatment in intermediate- and high-risk GIST patients. A: In the test cohort, among 74 DLK1-negative intermediate- and high-risk GIST patients, DFS of the patients with imatinib adjuvant treatment was significantly higher than that of the patients without imatinib adjuvant treatment (P = 0.022). B: In the validation cohort, among 41 DLK1-negative intermediate- and high-risk GIST patients, DFS of the patients with imatinib adjuvant treatment was significantly higher than that of the patients without imatinib adjuvant treatment (P = 0.046). C: In the test cohort, among 67 DLK1-positive intermediate- and high-risk GIST patients, there was no significant difference in DFS between the groups with or without imatinib adjuvant treatment (P = 0.612). D: In the validation cohort, among 46 DLK1-positive intermediate- and high-risk GIST patients, there was no significant difference in DFS between the groups with or without imatinib adjuvant treatment (P = 0.704).
