[New prospective on adjuvant treatment for gastrointestinal stromal tumors].

Gastrointestinal stromal tumor (GIST) represents the most common mesenchymal tumor of the gastrointestinal tract. With decades of development, surgical excision combined with molecular targeted agents is becoming the mode for the GIST treatment. Imatinib mesylate (IM) is the first-line therapy medicine for GIST adjuvant treatment, and it significantly reduces recurrence or metastasis and increases survival. According to the recently results of SSGXVIII/AIO study, imatinib adjuvant therapy should be administered for at least 3 years for the GIST patients with a high estimated risk of recurrence and metastasis after surgery. Nevertheless, the optimal duration of the adjuvant therapy or the follow-up policy remains unclear, and we look forward to standard assessment criteria for individualized treatment.
