The Korean adjuvant Phase II study referred to in this case report enrolled patients with resected primary GIST possessing KIT exon 11 mutations at high risk of recurrence (mitotic rate ≥5 mitoses/50 HPF and tumor size ≥5 cm, or mitotic rate ≥10 mitoses/50 HPF, or tumor size ≥10 cm) [9,10]. Here, KIT is linked to gastrointestinal stromal tumor.
