Pan-KRAS inhibitors BI-2493 and BI-2865 display potent anti-tumor activity in tumors with KRAS wild-type allele amplification.

KRASG12C selective inhibitors, such as sotorasib and adagrasib, have raised hopes of targeting other KRAS mutant alleles in cancer patients. We report that KRAS wild-type amplified tumor models are sensitive to treatment with the small molecule KRAS inhibitors BI-2493 and BI-2865. These pan-KRAS inhibitors directly target the "OFF" state of KRAS and result in potent anti-tumor activity in pre-clinical models of cancers driven by KRAS mutant proteins.

Imaging Findings and Management Strategies for Liver Masses in Children with Predisposition Disorders: A Review by the Pediatric LI-RADS Group.

Liver masses in children with underlying systemic disease or a predisposing syndrome can be benign or malignant, ranging from focal fat to hepatocellular carcinoma (HCC). Knowledge of the underlying condition, the pathophysiologic effect on the liver, and the development of liver disease and specific liver lesions allows radiologists to guide imaging with regard to modality and frequency and give recommendations for biopsy when appropriate. In some predisposition disorders, such as Beckwith Wiedemann spectrum, familial adenomatous polyposis syndrome, and tuberous sclerosis complex, established guidelines for imaging screening exist.

Successful Kidney Transplant From a Donor With Marfan Syndrome: A Case Report.

Marfan syndrome, a rare autosomal dominant connective tissue disorder caused by mutations in fibrillin-1, is primarily associated with cardiovascular complications such as aortic aneurysms and dissection. Despite the organ shortage crisis, kidneys from donors with Marfan syndrome are often rejected due to concerns about potential vascular complications. This case report presents the successful transplantation of a kidney from a 47-year-old male donor with Marfan syndrome into a 66-year-old female recipient with end-stage renal disease secondary to diabetic nephropathy.
