KIT Mutant Gastrointestinal Stromal Tumors with Lymphatic Metastasis

Lymph node metastasis of GIST is very rare, especially in adult GIST patients. However, there is a higher incidence of lymph node metastasis in pediatric patients with SDH-deficiency. The Chinese GIST diagnosis and treatment expert consensus and NCCN guidelines both recommend that routine lymph node dissection is not necessary for GIST surgery. At present, the relationship between GIST lymph node metastasis and prognosis remains less clear. This case reports a gastric GIST with KIT mutation and lymph node metastasis for reference.
