A rare case report of locally recurrent hemorrhagic duodenal gastrointestinal stromal tumor: therapeutic challenges and review of prognostic indicators for recurrence

Abstract: Gastrointestinal stromal tumor is a rare neoplasm affecting gastrointestinal tract. Duodenal gastrointestinal stromal tumor originating from the fourth segment is considered an extremely rare disease. Surgical challenges arise when managing locally recurrent hemorrhagic duodenal gastrointestinal stromal tumor. A 58-year-old male presented with melena for the last 10 days. Thirty months previously, he had segmental resection of the fourth duodenal portion due to hemorrhagic gastrointestinal stromal tumor. No ad… Show more

“…To achieve curative treatment of a GIST, complete tumour excision with negative margins is required. Lymph node dissection is not required [ 2 , 6 ]. In spite of complete excision with clear margins, GISTs tend to recur in ~50% of cases [ 6 ].…”

“…However recent research demonstrates that GI bleeding is due to tumour perforation through the mucosa and therefore should be treated similarly to cases where there has been tumour rupture, which changes the risk to high. These studies suggest that GI bleeding could be an independent risk factor for recurrence and therefore these patients require adjuvant treatment with imatinib [ 2 , 7 , 8 ].…”

“…Imatinib is also effective in large primary tumors of the duodenum to enhance surgical resection [4]. If there is tumor regression a duodenal local resection, especially in the 2 nd part, becomes possible without the need for a and invasion of the submucosal blood vessels [6,7]. This is thought to contribute to tumor embolization and local recurrence or distant metastases.…”
