The role of surgery in the multidisciplinary management of patients with localized gastrointestinal stromal tumors. Issue 8 (August 2012) - Bednarski, Brian K
Surgical resection of localized gastrointestinal stromal tumors (GISTs) is associated with recurrence rates of approximately 50% at 5 years of follow-up. The introduction of tyrosine kinase inhibitors, such as imatinib, improved overall survival rates in advanced disease, while in the adjuvant setting, improved recurrence-free survival following resection of high-risk GIST. The demonstration of the clinical benefit of tyrosine kinase inhibitors in both the metastatic and adjuvant settings generated interest in neoadjuvant approaches for patients with operable locally advanced disease, particularly in difficult anatomic locations. The potential impact of tumor downsizing in areas such as the gastroesophageal junction, the duodenum or the rectum, on the extent of surgical resection and morbidity is real. The ongoing research regarding neoadjuvant therapy, the duration of adjuvant therapy and the optimal means by which to risk stratify patients with GIST continues to keep the treatment of this disease at the forefront of personalized cancer care.
