Insights Imaging 2024; 15:169. [PMID: 38971944 PMCID: PMC11227487 DOI: 10.1186/s13244-024-01754-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Accepted: 06/16/2024] [Indexed: 07/08/2024] Open
Abstract
MRI offers new opportunities for detailed visualization of the different layers of the esophageal wall, as well as early detection and accurate characterization of esophageal lesions. Staging of esophageal tumors including extramural extent of disease, and status of the adjacent organ can also be performed by MRI with higher accuracy compared to other imaging modalities including CT and esophageal endoscopy. Although MDCT appears to be the primary imaging modality that is indicated for preoperative staging of esophageal cancer to assess tumor resectability, MDCT is considered less accurate in T staging. This review aims to update radiologists about emerging imaging techniques and the imaging features of various esophageal masses, emphasizing the imaging features that differentiate between esophageal masses, demonstrating the critical role of MRI in esophageal masses. CRITICAL RELEVANCE STATEMENT: MRI features may help differentiate mucosal high-grade neoplasia from early invasive squamous cell cancer of the esophagus, also esophageal GISTs from leiomyomas, and esophageal malignant melanoma has typical MR features. KEY POINTS: MRI can accurately visualize different layers of the esophagus potentially has a role in T staging. MR may accurately delineate esophageal fistulae, especially small mediastinal fistulae. MRI features of various esophageal masses are helpful in the differentiation.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108527. [PMID: 38968857 DOI: 10.1016/j.ejso.2024.108527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 06/23/2024] [Accepted: 06/30/2024] [Indexed: 07/07/2024]
Abstract
OBJECTIVE To explore the different treatment modalities for esophageal gastrointestinal stromal tumors (E-GIST) and their respective applicability and clinical outcomes. METHODS This is a retrospective study in which consecutive patients diagnosed with E-GIST at our hospital from January 2017 to August 2023 were included. The clinical characteristics of all the patients as well as long-term quality of life were recorded and analyzed. RESULTS A total of 23 (12 males, 11 females) E-GIST patients with a mean age of 56.7 ± 12.0 years were included in this study. Common symptoms, including upper abdominal pain, acid reflux, and heartburn, accounted for over 60 % of cases. Fifteen patients underwent endoscopic resection, five patients underwent surgical resection, two patients underwent surgical resection after receiving preoperative imatinib therapy, and one patient received conservative management. CONCLUSION Different treatment strategies may be applied to the patients with E-GIST depending on the their clinical features. Our study provides insights into precise treatment for different patients. However, due to the rarity of the disease, it is challenging to collect a large sample size from a single center, necessitating more multicenter prospective large-scale studies.

Abstract
Gastrointestinal stromal tumours (GISTs) are rarely encountered in pleural fluid samples. We report a case of GIST metastatic to pleural fluid almost two decades after the original diagnosis. Careful screening by a cytotechnologist, consideration of the clinical history, and judicious use of immunohistochemical stains facilitated the uncommon diagnosis.

Abstract
BACKGROUND Esophageal gastrointestinal stromal tumors(GISTs) are extremely rare. We sought to determine whether endoscopic treatment can be a viable therapeutic option for esophageal GISTs. METHODS A total of 20 cases with histological diagnosis of esophageal GISTs were obtained from our center between 2008 and 2020. Data on the clinicopathological features and treatment were recorded. RESULTS There were 9 males (45%) and 11 females (55%) in this study, with a median age of 56 years. The tumors preferentially occurred in the middle and lower parts of the thoracic esophagus (45 and 40%, respectively). The mean size of the tumors was 2.27 cm and mitotic index was no more than 5/50 high power field (HPF) in all patients. In this study, 11 patients received endoscopic treatment and nine patients underwent surgical resection. Tumors ranged from 0.6 to 4 cm in the endoscopic treatment patients and 0.5 to 7 cm in the surgical patients. There were no significant differences in gender, age, symptoms, tumor location, tumor size, mitotic index, and adjuvant imatinib therapy between the endoscopic treatment group and the surgery group (all p > .05). The Kaplan-Meier curve suggested that there was also no significant difference in disease-free survival between the two groups (p = .264). CONCLUSIONS Endoscopic treatment may be an option for the treatment of esophageal GISTs smaller than 5 cm with a mitotic index no more than 5/50 HPF.

Abstract
Gastrointestinal stromal tumor (GIST) are the most common non epithelial tumor of the gastrointestinal (GI) tract. They arise from interstitial cells of Cajal present in the myenteric plexus. They can also arise outside the GI tract from mesentery, retro peritoneum and omentum. With the advent of new targeted molecular therapy c- tyrosine kinase inhibitor (Imatinib), it has become important to differentiate between response and pseudo-progression of the disease as response evaluation criteria for GIST are different from Response Evaluation Criteria in Solid Tumors (RECIST). Purpose of this pictorial essay is to enumerate the characteristic CT features of GIST, and discuss atypical features and response evaluation criteria.

Abstract
An 87-year-old woman with leg-type lymphoma underwent a staging F-FDG PET/CT, which demonstrated besides leg lymphomatous lesions a round, well-defined, preduodenal mass with moderate FDG uptake. This mass remained unchanged after chemotherapy treatment completion, despite a complete metabolic response of lymphomatous lesions. A biopsy revealed a gangliocytic paraganglioma. Subsequent F-FDOPA PET/CT and somatostatin receptor scintigraphy were positive and did not depict any other lesions.

Abstract
PURPOSE We aimed to compare the computed tomography (CT) imaging differences between gastric and intestinal gastrointestinal stromal tumors (GISTs). MATERIALS AND METHODS Thirty-eight patients with 38 gastric GISTs and 27 with 31 intestinal GISTs were enrolled. Tumors were classified as small (< 5 cm) or large (≥ 5 cm). Qualitative and quantitative CT imaging characteristics on non-contrast and contrast-enhanced CT were evaluated by two radiologists independently and statistically compared. RESULTS Early venous return and higher CT number of the draining vein in the arterial phase were more frequent in small-sized intestinal GISTs than in small-sized gastric GISTs (p < 0.001). Small-sized intestinal GISTs demonstrated a wash-out pattern, whereas small-sized gastric GISTs showed a plateau pattern. Contrast enhancement was higher in small-sized intestinal GISTs than in small-sized gastric GISTs (p < 0.001). CT number was inversely proportional to the diameter of intestinal GISTs in both arterial and venous phases but not to that of gastric GISTs. CONCLUSION Strong enhancement with wash-out pattern and early venous return are characteristic findings of small-sized intestinal GISTs. Radiologists should be aware that CT findings of GISTs have a wide spectrum and may differ according to size and site of origin.

Abstract
Imaging plays an active role in the surveillance of gastrointestinal stromal tumours (GISTs). Risk stratification schemes, based on size, mitotic count, and anatomical site of origin of the GIST, help in planning preoperative and postoperative imaging strategies especially in determining the frequency and duration of surveillance; however, there is no clear consensus on the optimal imaging strategies in patients with GISTs who are completely cured by surgery and patients who are at risk of recurrence. In addition, current surveillance protocols depend on the resectability of the primary tumour and presence of metastatic disease. The objective of this article is to provide a comprehensive review of the role of the different imaging methods for surveillance of GISTs, focusing on the guidelines recommended by National Comprehensive Cancer Network and European Society of Medical Oncology - European Network for Rare adult solid Cancers, and to propose practical guidelines for surveillance of GISTs for various risk categories.

Abstract
Background Esophageal schwannomas are rare esophageal submucosal tumors. We herein report a case of a lobulated esophageal schwannoma resected with concurrent approach from the thorax and cervix. Case presentation A 74-year-old woman visited our hospital with complaint of loss of consciousness, and a lobulated mediastinal tumor was discovered by chance in computed tomography. Upper gastrointestinal endoscopy showed a smooth elevated lesion at a position of 23–28 cm from the incisor teeth. A hypermetabolic appearance was noted on positron emission tomography. Based on these data, a gastrointestinal stromal tumor was suspected. The tumor was enucleated at the thoracic cavity while being pushed from the cervical incision. Pathological examination showed an esophageal schwannoma. Conclusions We experienced a case of lobulated esophageal schwannoma with fluorodeoxyglucose accumulation. We resected the tumor with concurrent approach from the thorax and cervix.

Abstract
Gastrointestinal stromal tumors (GISTs) often arise in the stomach and small intestine, while esophageal GISTs are rare. Due to their rarity, clinicopathological data on esophageal GISTs are extremely limited, and this results in a lack of clear recommendations concerning optimal surgical management for esophageal GISTs. It is difficult to distinguish esophageal GIST from leiomyoma, the most frequent esophageal mesenchymal tumor, prior to resection, because the two types of tumors appear similar on computed tomography (CT), endoscopic ultrasound (EUS), and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET). Fine-needle aspiration biopsy (FNAB) under EUS enables definitive diagnosis, but it is often avoided because scarring could make enucleation more difficult and increase the risk of tumor dissemination by capsule destruction. Esophageal segmental and wedge resections are not usually performed due to the anatomical peculiarity of the esophagus, and the surgical options are limited to the highly invasive esophagectomy or the much less invasive surgical tumor enucleation. The decision as to which surgical procedure should be performed for esophageal GISTs is still under debate. Tumor enucleation may be permitted for smaller tumors, and esophagectomy may be recommended for larger GISTs or high-risk tumors with a high mitotic rate. The purpose of neoadjuvant imatinib administration is downsizing of the GIST to reduce the extent of resection and to reduce the risk of intraoperative complications, including tumor rupture. The efficacy of neoadjuvant/adjuvant imatinib therapy for esophageal GISTs is poorly understood, because the reports are limited to case reports or case series with small numbers. More clinicopathological data and clinical trials for esophageal GIST are expected.

Abstract
Gastrointestinal stromal tumors (GIST) are the most common type of gastrointestinal mesenchymal tumor, but are rarely found in the thoracic esophagus. There is no clear consensus about the optimal treatment of this rare disease. A systematic search of the literature was performed for localized esophageal GIST that was resected between 2000 and 2015, and individual patients were included from two major academic institutions. We obtained information on demographics, tumor size and location, mitotic rate, treatment method, and time to recurrence or death. We performed univariate and multivariate Cox regression analyses to evaluate the factors associated with recurrence or death. A total of 28 studies met our inclusion and exclusion criteria, and with two patients from two academic institutions, we had a total of 107 patients in the study. Due to lack of uniformity among studies, there were several missing data for different variables. The average patient age was 56 (n = 98) with mostly males (60%, n = 91). The average tumor size on the CT scan was 7.9 ± 5.4 cm (n = 91), located mostly in the distal esophagus (81%, n = 74). A similar number of patients underwent enucleation (n = 47) compared to esophagectomy (n = 42). Approximately half of the patients had a mitotic rate of 0-4 mitosis per 50 high-powered field (48%, n = 80). The median survival time was 73 months with a 5-year disease free survival of 57% (n = 97). Univariate Cox regression analyses showed that a large tumor, undergoing esophagectomy, and a high mitotic rate were associated with poor survival or recurrence control. We found that patients with a lesion smaller than or equal to 5 cm on the CT scan had a better disease-free survival rate than those with a size greater than 5 cm (HR = 12.41, p = 0.014) and had a 5-year survival rate of 92% with 90% of those patients undergoing enucleation (n = 29). Esophageal GIST is a very rare malignancy. The tumor size and mitotic rate of the tumor are associated with poor survival. However, patients with esophageal GIST measuring 5 cm or smaller may be safely treated with esophageal enucleation.

Abstract
AIMS Gastrointestinal stromal tumours (GISTs) may arise anywhere in the gastrointestinal tract, but are rare in the oesophagus. We describe the clinical, pathological and molecular characteristics of 27 primary oesophageal GISTs, the largest series to date. METHODS AND RESULTS DNA was extracted and exons 9, 11, 13 and 17 of KIT, exons 12, 14 and 18 of PDGFRA and exon 15 of BRAF were amplified and sequenced. Oesophageal GISTs occurred in 14 men and 13 women aged between 22 and 80 years (mean: 56 years). All 27 cases were immunohistochemically positive for KIT, and 92 and 47% co-expressed CD34 or smooth muscle actin, respectively. Fifteen (71% of analysed cases) harboured KIT exon 11 mutations and one case each had a mutation in KIT exon 13 (K642E) or BRAF exon 15 (V600E). Long-term follow-up data (median, 96.5 months) were obtained for 20 cases; two patients had metastases at presentation and seven had developed local recurrence and/or metastasis after surgery. A large tumour size (≥ 10 cm), high mitotic rate (> 5/5 mm2 ), presence of a deletion mutation in KIT exon 11 involving codons 557-558 and a positive microscopic margin were associated with recurrence and metastasis. The KIT mutations identified in oesophageal GISTs are similar to those observed in gastric GISTs. CONCLUSIONS Complete surgical resection with clear margins is recommended, if technically feasible, and genotyping can help to improve diagnosis and further patient management in oesophageal GIST.

Abstract
BACKGROUND Oesophageal GIST (ESOGIST) are very rare tumours requiring special consideration regarding diagnosis, surgical management, and perioperative treatment. METHODS A retrospective study was conducted across 9 centres in the French Sarcoma Group (FSG) to characterize all patients in the years 2000-2014. RESULTS Seventeen patients (pts) with primary localized ESOGIST were identified, with median age 69 years (36-81) and 11 females. Eight tumours (T) occurred in the lower third of the oesophagus, five in the oesophageal gastric junction, two in the superior third, and two in the middle third. All pts underwent oesophagoscopy and/or endoscopic ultrasound (EUS) and CT scan. Fifteen had EUS guided biopsy. Nine pts received Imatinib (IM) as initial treatment resulting in six PR, three SD. Tumours were resected in nine pts (53%) (7 upfront, 2 after IM); via enucleation in four (44%) [median size 4 cm], oesophagectomy in five (56%) [median size 10 cm]. Resections were R0 in three pts (33%), R1 in six (66%). Eight pts (47%) had no tumour resection, and one patient was never treated. Six pts received adjuvant IM. With a median follow-up of 24 months (7-101), 11 pts are alive (64.7%), five died (29.4%), one was lost to follow-up. Two pts of 4 pts relapsed following enucleation. CONCLUSIONS ESOGIST can be reliably identified pre-operatively by EUS-guided biopsy. Surgery for ESOGIST is either enucleation or oesophagectomy depending on tumour size, location, and patient's individual surgical risk. Preoperative IM therapy could improve resectability and should be considered if surgery is contraindicated or would lead to negative impact on the functional status of the patient.

Abstract
Clinicopathologic features and clinical outcomes of gastrointestinal stromal tumors (GISTs) in esophagus are limited, because of the relatively rare incidence of esophageal GISTs. Therefore, the aim of the current study was to investigate the clinicopathologic features and clinical outcomes of esophageal GISTs, and to investigate the potential factors that may predict prognosis.Esophageal GIST cases were obtained from our center and from case reports and clinical studies extracted from MEDLINE. Clinicopathologic features and survivals were analyzed and compared with gastric GISTs from our center.The most common location was lower esophagus (86.84%), followed by middle and upper esophagus (11.40% and 1.76%). The majority of esophageal GISTs were classified as high-risk category (70.83%). Mitotic index was correlated with histologic type, mutational status, and tumor size. The 5-year disease-free survival and disease-specific survival were 65.1% and 65.9%, respectively. Tumor size, mitotic index, and National Institutes of Health risk classification were associated with prognosis of esophageal GISTs. Only tumor size, however, was the independent risk factor for the prognosis of esophageal GISTs. In comparison to gastric GISTs, the distribution of tumor size, histologic type, and National Institutes of Health risk classification were significantly different between esophageal GISTs and gastric GISTs. The disease-free survival and disease-specific survival of esophageal GISTs were significantly lower than that of gastric GISTs.The most common location for esophageal GISTs was lower esophagus, and most of the esophageal GISTs are high-risk category. Tumor size was the independent risk factor for the prognosis of esophageal GISTs. Esophageal GISTs differ significantly from gastric GISTs in respect to clinicopathologic features. The prognosis of esophageal GISTs was worse than that of gastric GISTs.

Abstract
OBJECTIVE Small bowel (SB) is the second most common site of gastrointestinal stromal tumours (GISTs). We evaluated clinical presentation, pathology, imaging features and metastatic pattern of SB GIST. METHODS Imaging and clinicopathological data of 102 patients with jejunal/ileal GIST treated at Dana-Farber Cancer Institute and Brigham and Women's Hospital (Boston, MA) between 2002 and 2013 were evaluated. Imaging of treatment-naive primary tumour (41 patients) and follow-up imaging in all patients was reviewed. RESULTS 90/102 patients were symptomatic at presentation, abdominal pain and lower gastrointestinal blood loss being the most common symptoms. On pathology, 21 GISTs were low risk, 17 were intermediate and 64 were high risk. The mean tumour size was 8.5 cm. On baseline CT (n = 41), tumours were predominantly well circumscribed, exophytic and smooth/mildly lobulated in contour. Of 41 tumours, 16 (39%) were homogeneous, whereas 25 (61%) were heterogeneous. Of the 41 tumours, cystic/necrotic areas (Hounsfield units < 20) were seen in 16 (39%) and calcifications in 9 (22%). CT demonstrated complications in 13/41 (32%) patients in the form of tumour-bowel fistula (TBF) (7/41), bowel obstruction (4/41) and intraperitoneal rupture (2/41). Amongst 102 total patients, metastases developed in 51 (50%) patients (27 at presentation), predominantly involving peritoneum (40/102) and liver (32/102). 7/8 (87%) patients having intraperitoneal rupture at presentation developed metastases. Metastases elsewhere were always associated with hepatic/peritoneal metastases. At last follow-up, 28 patients were deceased (median survival, 65 months). CONCLUSION SB GISTs were predominantly large, well-circumscribed, exophytic tumours with or without cystic/necrotic areas. Complications such as TBF, bowel obstruction and intraperitoneal perforation were visualized at presentation, with patients with perforation demonstrating a high risk of metastatic disease. Exophytic eccentric bowel wall involvement and lack of associated adenopathy are useful indicators to help differentiate GISTs from other SB neoplasms. ADVANCES IN KNOWLEDGE SB GISTs are predominantly large, well-circumscribed, exophytic tumours, and may present with complications. They often are symptomatic at presentation, are high risk on pathology and metastasize to the peritoneum more commonly than the liver.

Abstract
Neoadjuvant imatinib for gastrointestinal stromal tumours (GISTs) is increasingly used nowadays. As oesophagectomy is associated with high morbidity and mortality, a preoperative downsizing of an oesophageal GIST to limit the extent of resection would be ideal. Because these tumours are rare and neoadjuvant treatment with imatinib is recent, there is limited literature available regarding neoadjuvant administration of imatinib in patients with oesophageal GISTs. A 50-year-old woman presented with total dysphagia. An upper endoscopy and biopsy revealed a large submucosal KIT-positive GIST obstructing the mid oesophagus. CT confirmed a lesion measuring 99 mm × 50 mm × 104 mm. Because the size and location of the tumour increased the risk of intraoperative rupture, it was decided to administer preoperative imatinib. The patient had an excellent clinical and radiological response. Her dysphagia gradually resolved and the follow-up CT scans of the first 10 months showed a gradually reducing tumour size to 54 mm × 33 mm × 42 mm. The patient underwent an uneventful laparoscopic-assisted Ivor-Lewis oesophagectomy. Postoperatively, the patient continued with adjuvant imatinib. At the last follow-up, 1 year from operation and 38 months from the diagnosis, the patient is disease free.

Abstract
Benign esophageal and paraesophageal masses and cysts are a rare but important group of pathologies. Although often asymptomatic, these lesions can cause a variety of symptoms and, in some cases, demonstrate variable biological behavior. Contemporary categorization relies heavily on endoscopic ultrasound and other imaging modalities and immunohistochemical analysis when appropriate. Minimally invasive options including endoscopic, laparoscopic, and thoracoscopic methods are increasingly used for symptomatic or indeterminate lesions.

Abstract
INTRODUCTION Sparse information is available about GISTs in uncommon locations. Our large database analysis aims to determine the characteristics of GISTs in the esophagus, colon and rectum and compare to gastric GISTs. METHODS The Surveillance Epidemiology and End Results (SEER) database was queried from 1990 to 2009 using CS SCHEMA v0203. Characteristics of each location were compared to gastric GISTs. RESULTS 4411 GIST (29 esophageal, 2658 stomach, 1463 small intestine, 126 colonic, and 135 rectal) from 1990 to 2009 were identified. Univariate and multivariate predictors of worse disease specific survival in both the entire cohort and surgical resection group include older age, male gender, tumor size > 5 cm, no surgical intervention and anatomical location. Although less likely to undergo surgical resection, esophageal GIST (all patients and resected) had a comparable survival to gastric GIST. A higher proportion of colonic GISTs presented with distant disease and had a worse disease specific survival when compared to rectal GISTs. CONCLUSION Our results show a rising incidence in GISTs and highlight the characteristics of GISTs based on anatomical location. In addition, this is the first study to demonstrate that colonic GISTs behave differently when compared to rectal GISTs and warrants further prospective evaluation.

Abstract
OBJECTIVE The purpose of this article is to describe the imaging and clinicopathologic characteristics of esophageal gastrointestinal stromal tumors (GISTs) and to emphasize the features that differentiate esophageal GISTs from esophageal leiomyomas. MATERIALS AND METHODS A pathology database search identified all surgically resected or biopsied esophageal GISTs, esophageal leiomyomas, and esophageal leiomyosarcomas from 1994 to 2012. Esophageal GISTs were included only if imaging studies (including CT, fluoroscopic, or (18)F-FDG PET/CT scans) and clinical data were available. RESULTS Nineteen esophageal mesenchymal tumors were identified, including eight esophageal GISTs (42%), 10 esophageal leiomyomas (53%), and one esophageal leiomyosarcoma (5%). Four patients (50%) with esophageal GIST had symptoms, including dysphagia in three (38%), cough in one (13%), and chest pain in one (13%). One esophageal GIST appeared on barium study as a smooth submucosal mass. All esophageal GISTs appeared on CT as well-marginated predominantly distal lesions, isoattenuating to muscle, that moderately enhanced after IV contrast agent administration. Compared with esophageal leiomyomas, esophageal GISTs tended to be more distal, larger, and more heterogeneous and showed greater IV enhancement on CT. All esophageal GISTs showed marked avidity (mean maximum standardized uptake value, 16) on PET scans. All esophageal GISTs were positive for c-KIT (a cell-surface transmembrane tyrosine kinase also known as CD117) and CD34. On histopathology, six esophageal GISTs (75%) were of the spindle pattern and two (25%) were of a mixed spindle and epithelioid pattern. Five esophageal GISTs had exon 11 mutations (with imatinib sensitivity). Clinical outcome correlated with treatment strategy (resection plus adjuvant therapy or resection alone) rather than risk stratification. CONCLUSION Esophageal GISTs are unusual but clinically important mesenchymal neoplasms. Although esophageal GISTs and esophageal leiomyomas had overlapping imaging features, esophageal GISTs tended to be more distal, larger, more heterogeneous, and more enhancing on CT and were markedly FDG avid on PET. Given their malignant potential, esophageal GISTs should be included in the differential diagnosis of intramural esophageal neoplasms.

Abstract
Malignant esophageal neoplasms other than squamous cell carcinoma and adenocarcinoma are uncommon and include endocrine tumors, lymphoid malignancies, melanoma, malignant stromal tumors, and secondary tumors (metastases). Imaging, though not diagnostic in many cases, helps in selecting the appropriate treatment strategy by determining the anatomic extent of the tumor and locoregional and distant spread. In this article, we provide a comprehensive review of the imaging features of these uncommon esophageal malignancies.
