Standard of postoperative risk assessment for resectable gastrointestinal stromal tumor and its evaluation

Surgery is the only possible cure protocol of gastrointestinal stromal tumor(GIST).But the risk of recurrence exists constantly.Risk assessment of relapse is very important to guide the targeted adjuvant therapy and predict the prognosis.Although the variables and grading in the risk assessment of recurrence after complete resection of primary local GIST have been identified,but either the F/NIH consensus,AFIP standards,modified NIH standards,or risk identification methods attempted to apply mathemafical calculation model in recent years,including Jason S Gold risk nomogram,Rossi nomogram,Joensuu high Hotline Dengjun,are short of long-term,large-scale clinical trials withou selection bias.Therefore,recurrence risk probability cannot be predicted accurately.
