Furthermore, research must investigate epidemiological issues, therapeutic methods, and follow-up procedures in Saudi Arabia. Guidelines for managing and following up on these cases should be developed based on the agreed-upon processes.
Postoperatively, the patient recovered well and was treated with adjuvant imatinib...Comprehensive workup, wide excision with negative margins, and targeted therapy are essential. Increased awareness and reporting are needed to guide management.
Thus, reduction in level of ITGB1 in resistant cells leads to activation of ERK and p38MAPK belonging to BCR::ABL1 pathway, despite inactivation of BCR::ABL1, which in turn leads to activation of LYN. Together, these kinases activate members of vital pro-survival pathways, thereby imparting imatinib resistance in CML-BC cells.
The patient recovered uneventfully and was started on treatment with imatinib mesylate...GISTs should be considered in cases of unexplained SBV. This case emphasizes the diagnostic challenges, the need for prompt surgical palliation, and the role of systemic tyrosine kinase inhibitors in advanced presentation of GIST.
Activating mutations in KIT or PDGFRA characterize most GISTs and confer sensitivity to imatinib, whereas succinate dehydrogenase (SDH)–deficient GISTs lack these mutations and are typically imatinib resistant...Pathology demonstrated spindle cell GIST with significant treatment effect and retained SDHB expression. This case suggests that oncogenic KIT signaling may remain the dominant driver of GIST behavior despite the presence of a germline SDHC mutation and highlights the importance of integrated molecular interpretation in GIST management.

Although tyrosine kinase inhibitors (TKIs), particularly imatinib, have substantially improved outcomes, most patients with advanced disease eventually develop resistance, resulting in disease progression...Molecular stratification and personalized approaches dominate ongoing research, but evidence generation remains limited by small sample sizes and slow recruitment. Future trials integrating innovative therapeutic platforms and patient-centered outcomes are essential to improve long-term disease control and quality of life.
Imatinib-based combinations suppress 3D endometrial cancer growth predominantly through sustained cell cycle arrest rather than apoptosis induction. Targeting apoptosis-resistant proliferation through cytostatic mechanisms may represent a complementary therapeutic strategy for hormone-responsive endometrial cancer and warrants further translational evaluation.
Both IM and ZEB combination showed promise in the management of CRC by inducing oxidative stress, promoting apoptosis, and modulating critical genes involved in metastasis and apoptosis. Further investigation will be needed to verify their application in preclinical and clinical settings.
In this setting, Peg-IFN combined with nilotinib induced higher initial rates of MR4·5 compared to TKI monotherapy, despite additional side effects. The onset of psychiatric events might promote immediate cease of Peg-IFN and psychiatrist advice Whether this early molecular response translates into sustained treatment-free survival should be studied in a randomised trial sufficiently powered for this outcome.
Cycloheximide chase assays indicated accelerated AIRE protein degradation, while MG132 partially rescued AIRE levels, implicating proteasome-dependent degradation. Overall, Nilotinib suppresses ESCC progression by inhibiting ILK and destabilising AIRE, suggesting its potential as a targeted therapy for ILK-positive ESCC.
