Surgical treamtent of giant gastrointestinal mesenchymal tumor after neoadjuvant therapy: a case report and review of the literature
Objective:To report a case of giant gastrointestinal mesenchymal tumor treated by surgical resection after neoadjuvant therapy, and to investigate the optimal timing of surgery for giant gastrointestinal mesenchymal tumor preoperatively treated with imatinib mesylate by reviewing the relevant literature.Methods:A case of giant gastrointestinal mesenchymal tumor is reported and the relevant literature is reviewed.Results:A 47-year-old woman presented with abdominal mass, abdominal pain, and abdominal distension, and she was diagnosed as having malignant gastrointestinal malignant mesenchymal tumor by CT and puncture biopsy. The maximum diameter of the tumor was about 233 mm × 117 mm × 213 mm at the initial diagnosis. No recurrence of metastasis was observed in the postoperative follow-up to date.Conclusion:For patients with initially unresectable giant gastrointestinal mesenchymal tumor, surgery can be chosen when the maximum benefit of molecular targeted drug therapy is achieved to improve the R0 resection rate.
