While gastrointestinal stromal tumors have been increasingly recognized with the prolonged survival and highly effective new targeted treatments, the role of imaging has become important not only for diagnosing and staging the tumors, but also for monitoring the effects of treatment and surveillance. Computed tomography is the imaging modality of choice for these purposes. Fluorine-18 fluorodeoxyglucose positron emission tomography is primarily used in problem solving when there are inconsistencies between CT and clinical findings or inconclusive CT images. The roles of MRI and ultrasound are also described.

Gastric schwannoma with post-surgical gastroparesis: a case report and literature review.

Gastric schwannoma is a relatively rare submucosal mesenchymal tumor with low probability of metastasis and arises from Schwann cells of the gastrointestinal nervous plexus. Surgical therapy is the main treatment of gastric schwannoma with symptoms or malignant tendency. Gastroparesis is a potential complication following gastrointestinal surgery, which is a clinical syndrome caused by gastric emptying disorder and characterized by nausea, vomiting, and bloating, resulting in insufficient nutrient intake.

Background: This study aimed to investigate the clinical characteristics and esophageal motility of patients with gastric cardia submucosal tumors (SMTs) and the associated changes after endoscopic resection based on high-resolution impedance manometry (HRIM).
Methods: From our electronic database, we identified patients who underwent pre-operative evaluation of gastric cardia SMTs between 2015 and 2023. All patients completed standardized symptom questionnaires and underwent endoscopic ultrasonography and HRIM.

The variability in translational models profoundly impacts the outcomes and predictive value of preclinical studies for gastrointestinal (GI) cancer treatments. Preclinical models, including 2D cell cultures, 3D organoids, patient-derived xenografts (PDXs), and animal models, provide distinct advantages and limitations in replicating the complex tumor microenvironment (TME) of human cancers. Each model's unique biological and structural differences contribute to discrepancies in treatment responses, challenging the direct translation of experimental results to clinical settings.

Rectal gastrointestinal stromal tumors (GISTs) are often asymptomatic and may be detected as giant tumors. This may require highly invasive surgery for radical resection. Here, we describe a 74-year-old man with a locally advanced non-metastatic GIST in the right anterolateral wall of the lower rectum.

PSMA-PET/CT has emerged as a superior diagnostic tool for prostate cancer, demonstrating enhanced accuracy over conventional imaging methods. Although sensitive for detecting local and metastatic prostate tumors, it can also identify other non-prostate PSMA positive lesions. Here, we report a rare case of a 67-year-old patient with metastatic prostate adenocarcinoma who was found to have an incidental Gastrointestinal Stromal Tumor (GIST), during restaging with 68Ga-PSMA-11 PET/CT.
