Gastrointestinal Stromal Tumor Advanced Stage And High Fever Symptoms

Most patients with advanced gastrointestinal stromal tumor (GIST) do not typically experience high fever. However, in rare and specific cases, elevated body temperature can occur. GIST primarily develops as a space-occupying lesion within the stomach wall, often leading to ulceration and bleeding rather than systemic symptoms like fever.

When the tumor grows inward into the stomach cavity, it may cause internal bleeding, which typically presents as black stools, vomiting blood, and generalized fatigue. These symptoms are more common than fever in GIST patients. On the other hand, if the tumor grows outward from the stomach wall, it may not cause noticeable bleeding symptoms and can present only with abdominal discomfort or bloating.

In such cases, the tumor is usually detected through imaging techniques like CT scans. If the tumor is located inside the gastric cavity, a gastroscopy can help identify it. Fever may occur if there is tumor-related bleeding, necrosis, or infection, but sustained high fever is uncommon.

It's important to note that if a GIST patient does experience persistent fever, it may indicate secondary complications rather than the tumor itself. High fever is rarely the primary symptom that leads patients to seek medical attention for GIST. Clinicians usually observe other more prominent signs before fever becomes a concern. Therefore, fever alone is not considered a typical presenting symptom of advanced GIST.
