Although there were no ill effects noted in either case, perhaps due to the brief exposure of both dexamethasone and imatinib, a more prolonged exposure of the two medications may benefit from possible monitoring of plasma imatinib levels especially in the setting of metastatic GIST (case one). Modifications to the treatment could include increasing the dosage of imatinib, decreasing the dosage of dexamethasone, or administering another anti-emetic in lieu of dexamethasone. Conclusion There have Inhibitors,research,lifescience,medical been very few incidences of synchronous colorectal cancer and GISTs reported in literature. Most

of the cases described were found due to other malignancies or discovered incidentally during surgery (3),(5),(15). The two Inhibitors,research,lifescience,medical cases

presented above underline the importance of being aware of this particular coexistence as well as the unlikely metastatic spread of GIST to lymph nodes, development of other primary tumours during treatment of metastatic GIST, and the importance of a multidisciplinary approach to cancer treatment. Footnotes No potential conflict of interest.
Due to the variety of therapeutic options that are currently available for patients diagnosed with Barrett’s-related high-grade dysplasia (BE-HGD), the choice of optimal management continues to be a topic of discussion among gastroenterologists, surgeons, oncologists, Inhibitors,research,lifescience,medical pathologists, and patients. Per the current American College of Gastroenterology guidelines, HGD is considered a threshold for therapeutic intervention (1). The choice of management ranges from the most conservative approach – continued WP1130 molecular weight endoscopic surveillance (2),(3) to the most aggressive option – esophagectomy, with Inhibitors,research,lifescience,medical endoscopic therapies such as endoscopic mucosal resection (4) and ablation therapy somewhere in the middle

(5). The potential to completely eradicate the diseased segment Inhibitors,research,lifescience,medical as well as the fact that 12.7%-75% (mean-39.3%) of patients with a pre-operative diagnosis of HGD will harbor adenocarcinoma on esophageal resection (6) are the most compelling reasons in favor Calpain of esophagectomy. Esophagectomy, however, is associated with significant mortality and morbidity, with estimates of mortality ranging from 0%-2% at high-volume centers to 8%-10% at low volume centers (7). On the contrary, with significant advances in endoscopic techniques, the role of esophagectomy is becoming restricted to patients diagnosed with multifocal dysplasia who have failed endoscopic therapy and patients in whom pre-operative imaging modalities such as endoscopic ultrasound staging (EUS) suggest the presence of at least submucosal disease. Compared to that which had been found in earlier studies, where up to 40% of patients with a pre-operative diagnosis of HGD demonstrated adenocarcinoma on resection, Konda et al in a meta-analysis of 23 studies found that only 12.
