Patients and Methods: A total of 34 adult patients already receiving imatinib were enrolled. Recurrence-free (RFS) and overall survival, as well as time to treatment failure and safety were assessed. Results: Overall survival could not be estimated in the present study, as no death occurred. Overall, 91.2% of patients were recurrence-free at 36 months, while the median time to treatment failure was 35 months. No new or unexpected safety findings were observed. Mutation analysis in 14 patients showed that the most frequent mutations were located in KIT exon 11 (64.3%) and exon 9 (28.6%). Univariate analysis showed that only surgical resection with a margin classification of R0 was associated with better RFS. Conclusion: Adjuvant treatment with imatinib for 3 years in patients with intermediate to high risk of recurrence was proven to prolong RFS, while being well-tolerated and not exhibiting a negative impact on patient compliance with therapy.
