The calculator provides the estimated risk for GIST recurrence within the first 10 years since surgery for a localized, operable GIST.

The risks are estimations based on pooled population-based series [1]. The risk tables also provide risk estimations. The source data are historical, and may not apply directly to present circumstances, and adjuvant Imatinib may substantially reduce the risk of recurrence.
