Adjuvant tyrosine kinase inhibitors, such as imatinib, are reserved for high-risk lesions or unresectable tumors. This case highlights the importance of considering GIST as a differential diagnosis in obscure upper GI bleeding. It also demonstrates that laparoscopic resection is a safe and effective treatment option for ileal GISTs, even in the context of acute bleeding.
For therapeutic categories, performance reached 0.84 for avapritinib sensitivity and 0.81 for imatinib sensitivity. Prognostic performance was comparable to pathology-based scores, with highest discrimination in the overall cohort and in patients without adjuvant therapy. DL applied to WSIs enables prediction of molecular alterations, treatment sensitivity, and RFS in GIST, performing comparably to established risk scores across international cohorts, providing a baseline for future multimodal predictors.
The study also showed the inherent resistance of the KIT p.Ala829Pro mutation to imatinib, explaining the failure of subsequent treatment. This study highlights the significant spatial and temporal heterogeneity of acral melanoma and underscores the critical importance of serial biopsies in accurately capturing clonal dynamics and guiding precision oncology therapy.
PRKCA and ABCB1 dual-enriched exosomes are key drivers of drug resistance in CML patients, and exosomal PRKCA and ABCB1 may serve as diagnostic and therapeutic targets for CML.

ABCB1 (ATP Binding Cassette Subfamily B Member 1) • FOXA1 (Forkhead Box A1) • ETS1 (ETS Proto-Oncogene 1) • PRKCA (Protein Kinase C Alpha) • MARCKS (Myristoylated Alanine Rich Protein Kinase C Substrate)
On follow-up PET-CT scan after imatinib therapy, the patient showed a complete/near complete metabolic response. This report expands the imaging spectrum of PHGIST and emphasizes the importance of radiologic-pathologic correlation in distinguishing this rare lesion from metastatic liver disease.
