[Re-appraisal of risk assessment schemes in gastrointestinal stromal tumors]

The biological behavior of gastrointestinal stromal tumor(GIST) is highly variable. To assess the risk of recurrence of the primary tumor accurately is a key challenge. The risk assessment system of GIST has experienced several revolutions. The present accepted risk stratification scheme is still to be consummated. The pathological morphological characteristics, mutational features, and other biomarkers are helpful to improve the risk assessment system. The risk assessment of GIST in the future will be more and more diversified.
