Abstract

Purpose While targeted inhibitors of tyrosine kinase activity demonstrate dramatic efficacy in the majority of patients with advanced gastrointestinal stromal tumors (GISTs), cure remains elusive and resistance to systemic therapy is a challenge. To assess the role of surgery in multimodality management of GISTs, we studied postoperative outcomes in patients treated with targeted kinase inhibitors for advanced GIST. Methods We evaluated outcomes in a single institution series of 69 consecutive patients who underwent surgery for advanced GISTs while receiving kinase inhibitors. Patients were categorized based on extent of disease before surgery (stable disease, limited disease progression, generalized disease progression) and surgical result (no evidence of disease, minimal residual disease, bulky residual disease). Results Disease status before surgery was associated with surgical result (P < .0001; median follow-up, 14.6 months). After surgery, there was no evidence of disease in 78%, 25%, and 7% of patients with stable disease, limited progression, and generalized progression, respectively. Bulky residual disease remained after surgery in 4%, 16%, and 43% of the patients with stable disease, limited progression, and generalized progression. Twelve-month progression-free survival was 80%, 33%, and 0% for patients with stable disease, limited progression, and generalized progression (P < .0001). Twelve-month overall survival was 95%, 86%, and 0% for patients with stable disease, limited progression, and generalized progression (P < .0001). Conclusion Patients with advanced GISTs exhibiting stable disease or limited progression on kinase inhibitor therapy have prolonged overall survival after debulking procedures. Surgery has little to offer in the setting of generalized progression.
