Clinical outcomes of tumor bleeding in duodenal gastrointestinal stromal tumors: a 20-year single-center experience. Surg Endosc 2020; 35:1190-1201. [PMID: 32170563 DOI: 10.1007/s00464-020-07486-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Accepted: 03/02/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Duodenal gastrointestinal stromal tumors (GISTs) are rare, and reports on duodenal GIST bleeding are few. We analyzed the risk factors and clinical outcomes of hemorrhagic duodenal GISTs and compared them with those of gastric GISTs. METHODS Primary duodenal GISTs surgically diagnosed between January 1998 and December 2017 were retrospectively reviewed. Furthermore, patients with duodenal GIST were compared with those with primary gastric GIST histopathologically diagnosed between January 1998 and May 2015 using previously published data. RESULTS Of the 170 total patients with duodenal GISTs, 48 (28.2%) exhibited tumor bleeding. Endoscopic intervention, embolization, and non-interventional conservative treatment were performed for initial hemostasis in 17, 1, and 30 patients, respectively. The 5-year survival rate was 81.9% in the bleeding group and 89.4% in the non-bleeding group (P = 0.495). Multivariate analysis showed that p53 positivity was a significant risk factor for duodenal GIST bleeding (hazard ratio [HR] 2.781, P = 0.012), and age ≥ 60 years (HR 3.163, P = 0.027), a large maximum diameter (comparing four groups: < 2, 2-5, 5-10, and ≥ 10 cm), and mitotic count ≥ 5/high-power field (HPF) (HR 3.265, P = 0.032) were risk factors for overall survival. The incidence of bleeding was significantly higher in duodenal GISTs than in gastric GISTs (28.2% vs. 6.6%, P < 0.001), and the re-bleeding rate after endoscopic hemostasis was also higher in duodenal GISTs than in gastric GISTs (41.2% vs. 13.3%, P = 0.118). CONCLUSION In patients with duodenal GIST with old age, large tumor diameter, and mitotic count ≥ 5/HPF, a treatment plan should be established in consideration of the poor prognosis, although tumor bleeding does not adversely affect the prognosis. Duodenal GISTs have a higher incidence of tumor bleeding and re-bleeding rate after endoscopic hemostasis than gastric GISTs.

Clinical outcomes of upper gastrointestinal bleeding in patients with gastric gastrointestinal stromal tumor. Surg Endosc 2019; 34:696-706. [PMID: 31062158 DOI: 10.1007/s00464-019-06816-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2019] [Accepted: 04/29/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND Upper gastrointestinal bleeding (UGIB) is one of the major manifestations of gastrointestinal stromal tumor (GIST) of the stomach. Several studies have reported that GIST bleeding is associated with poor prognosis. However, only case reports have reported hemostasis modalities for treating hemorrhagic gastric GIST. To identify clinical outcome of gastric GIST bleeding, we analyzed risk factors and prognosis of hemorrhagic GIST evaluating hemostasis methods. METHODS Total 697 patients histopathologically diagnosed with primary gastric GIST between January 1998 and May 2015 were enrolled to the study, retrospectively. RESULTS Of 697 total patients, 46 (6.6%) patients had UGIB. Endoscopic intervention, transarterial embolization, or surgical intervention was performed for initial hemostasis in 15, 2, and 1, respectively. Over a median of 68 months of follow-up, 16 patients in bleeding group and 88 patients in non-bleeding group died; the 5-year survival rate was 79.4% in bleeding group and 91.8% in non-bleeding group (p = 0.004). Multivariate analysis showed that significant risk factors for gastric GIST bleeding included the maximal tumor diameter > 5 cm and Ki-67 positivity. Age ≥ 60 [hazard ratio (HR) = 8.124, p = 0.048], necrosis (HR = 5.093, p = 0.027), and bleeding (HR 5.743, p = 0.034) were significant factors for overall survival of gastric GIST patients. CONCLUSIONS Bleeding risk of gastric GIST was higher when tumor had diameter > 5 cm or Ki-67 positivity. In addition, tumor bleeding, necrosis, and age ≥ 60 years were associated with poor overall survival. Endoscopic intervention can be considered as an effective method for initial hemostasis of hemorrhagic gastric GIST.

Duodenal wedge resection for large gastrointestinal stromal tumour presenting with life-threatening haemorrhage. Case Rep Gastrointest Med 2013; 2013:562642. [PMID: 23634309 PMCID: PMC3619631 DOI: 10.1155/2013/562642] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2013] [Accepted: 02/26/2013] [Indexed: 11/29/2022] Open
Abstract
Background. Duodenal gastrointestinal stromal tumours (GISTs) are an uncommon malignancy of the gastrointestinal (GI) tract. We present a case of life-threatening haemorrhage caused by a large ulcerating duodenal GIST arising from the third part of the duodenum managed by a limited duodenal wedge resection. Case Presentation. A 61-year-old patient presented with acute life-threatening gastrointestinal bleeding. After oesophagogastroduodenoscopy failed to demonstrate the source of bleeding, a 5 cm ulcerating exophytic mass originating from the third part of the duodenum was identified at laparotomy. A successful limited wedge resection of the tumour mass was performed. Histopathology subsequently confirmed a duodenal GIST. The patient remained well at 12-month followup with no evidence of local recurrence or metastatic spread. Conclusion. Duodenal GISTs can present with life-threatening upper GI haemorrhage. In the context of acute haemorrhage, even relatively large duodenal GISTs can be treated by limited wedge resection. This is a preferable alternative to duodenopancreatectomy with lower morbidity and mortality but comparable oncological outcome.

Patient with high-risk GIST not associated with c-KIT mutations: same benefit from adjuvant therapy? Anticancer Drugs 2012; 23 Suppl:S7-9.

Abstract
A patient was diagnosed with neurofibromatosis type 1 (NF1) and gastrointestinal stromal tumour (GIST). This is not simply a coincidence; numerous molecular and genetic studies have established a close relationship between the two disorders, suggesting that GIST should be included in the clinical spectrum of NF1. In NF1 presenting GIST, the tumour usually develops in the small intestine. We present a 51-year-old woman diagnosed with NF1, who on follow-up showed an intra-abdominal mass. The pathological study of the mass after surgery led to the diagnosis of GIST with no mutations in exons 9, 11, 13 and 17 of the c-KIT gene or in exons 12, 14 and 18 of the platelet-derived growth factor receptor α gene. Imatinib was initiated as coadjuvant therapy with good tolerance, no toxicity and without evidence of relapse during follow-up.
