Adjuvant treatment of GIST with imatinib: Solid ground or still quicksand? A comment on behalf of the EORTC Soft Tissue and Bone Sarcoma Group, the Italian Sarcoma Group, the NCRI Sarcoma Clinical Studies Group (UK), the Japanese Study Group on GIST, the French Sarcoma Group and the Spanish Sarcoma Group (GEIS)

      Mutations of the KIT gene are the molecular hallmark of most GISTs, and were first reported more than 10 years ago.

      Since then, GIST has become a tumour model for targeted treatment of solid tumours, imatinib becoming the standard first line treatment of these tumours in the advanced phase.

      Following the introduction of imatinib, the median survival of advanced GIST increased from 18 months to 60 months in the most recent update of the B2222 trial, i.e. the trial with the longest follow-up so far.
