AI Article Synopsis
- Gastrointestinal stromal tumors (GISTs) are controversial among pathologists regarding their origin, classification, and potential for malignancy.
- Prior to 1998, GISTs were often misclassified as other types of mesenchymal tumors due to a lack of understanding until KIT gene mutations were identified.
- When a GIST is detected, imaging tests like ultrasounds and CT scans help determine the size and location of the tumor, typically found in the stomach or intestines, allowing the medical team to narrow down the diagnosis.
Article Abstract
Since they were described, gastrointestinal stromal tumors (GISTs) are, for pathologists and not only for them, a subject of controversy regarding histological origin, differentiation, nomenclature, malignant potential and prognosis. Before 1998, there were no certainties that GISTs were fundamentally different from other types of abdominal cancers in the big family of mesenchymal tumors. Before the discovery of KIT gene mutations, GISTs were most often classified as leiomyoma, leiomyosarcoma, leiomyoblastoma, and gastrointestinal autonomic nerve tumor. When a tumor is discovered, the first data obtained are initially assessed by one or more imaging tests, such as an ultrasound, computed tomography scan or magnetic resonance imaging. The imaging results define the size of the lesion and its anatomic location, which in the case of GIST is usually within the wall of the stomach or intestine. Depending on the experience of the medical team - radiologist, gastroenterologist or surgeon - reviewing the imagistic tests and correlating them with the general patient profile, the differential diagnostic is reduced and GIST may become the main suspect.

Department of Clinical Science, Intervention and Technology (CLINTEC), Division of Surgery and Oncology, Karolinska Institutet, Hälsovägen 13, 141 57, Huddinge, Stockholm, Sweden.
Background: The standard treatment for advanced gastric cancer without metastasis is gastrectomy in combination with chemotherapy. Some patients cannot tolerate such treatment because of old age or comorbidities. In this study, we want to test the feasibility of Laparoscopic and Endoscopic Cooperative Surgery (LECS) as a less invasive treatment option.

Background: Textbook outcome (TO) has been utilized to assess the quality of surgical care. This study aimed to define TO rates for minimally invasive gastric gastrointestinal stromal tumor (GIST) resections in a bi-institutional cohort.
Methods: Patients with gastric GIST (≤ 5 cm) who underwent laparoscopic or robotic resection (January 2014 to January 2024) were retrospectively identified from two GIST centers.

Imatinib resistance is a major obstacle to the successful treatment of gastrointestinal stromal tumors (GIST). Long non-coding RNAs (LncRNAs) have been identified as important regulatory factors in chemotherapy resistance. This study aimed to identify key lncRNAs involved in imatinib resistance of GISTs.

Objective: This study aims to develop and validate an enhanced computed tomography (CT)-based radiomics model to differentiate gastric schwannomas (GS) from gastrointestinal stromal tumors (GIST) across various risk categories.
Methods: This retrospective analysis was conducted on 26 GS and 82 GIST cases, all confirmed by postoperative pathology. Data was divided into training and validation cohorts at a 7:3 ratio.

Department of Radiology, Lanzhou University Second Hospital, Cuiyingmen No.82, Chengguan District, Lanzhou, 730030, People's Republic of China.
Purpose: To assess and compare the diagnostic efficiency of histogram analysis of monochromatic and iodine images derived from spectral CT in predicting Ki-67 expression in gastric gastrointestinal stromal tumors (gGIST).
Methods: Sixty-five patients with gGIST who underwent spectral CT were divided into a low-level Ki-67 expression group (LEG, Ki-67 < 10%, n = 33) and a high-level Ki-67 expression group (HEG, Ki-67 ≥ 10%, n = 32). Conventional CT features were extracted and compared.
