These include the tumour's size, mitotic count (rate of cell division), site of origin within the gastrointestinal tract (gastric lesions are less aggressive), and perforation. These criteria help classify GISTs into risk categories, guiding clinicians in assessing the tumour's aggressiveness and determining the most appropriate course of treatment.\u003c/p\u003e","id":2900,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2900","nextQuestionPath":"/articles/gastrointestinal-stromal-tumour-1/questions/2626","relatedArticles":[],"alsoUsedIn":[],"stem":"\u003cp\u003eHow is the malignant potential of a gastrointestinal stromal tumour (GIST) determined?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/2900"}],"attemptsPercentages":[{"alternativeId":"14139","percentage":6},{"alternativeId":"14140","percentage":25},{"alternativeId":"14138","percentage":19},{"alternativeId":"14141","percentage":3},{"alternativeId":"14142","percentage":47}],"promptToLogin":false,"questionManager":false,"articleId":"gastrointestinal-stromal-tumour"}
