Department of Medical Oncology, Affiliated Cancer Hospital of Zhengzhou University (Henan Cancer Hospital), Zhengzhou, China.
Background: Gastric cancer (GC) is one of the leading contributors to global malignancies incidence and mortality worldwide. Advanced GC had a relatively poor prognosis. The emerging of targeted therapy improved the survival and prognosis of GC patients.

Extra-skeletal Ewing sarcoma is a rare tumor, most commonly occurring in the paravertebral region, extremities, retroperitoneum, and very rarely in visceral locations. We present two primary visceral Ewing sarcomas confirmed at the molecular level: one located in the stomach and the other in the bladder. Both tumors demonstrated strong and diffuse membranous CD99 expression, accompanied by variable KIT immunoreactivity.

Activation of the p38 mitogen-activated protein kinase (MAPK) pathways is vital in regulating cell growth, differentiation, apoptosis, and stress response, significantly affecting tumorigenesis and cancer progression. We developed a bioinformatic technique to construct an interactome network-based molecular pathways for genes of interest and quantify their activation levels using high-throughput gene expression data. This study is focused on the p38α, p38β, p38γ, and p38δ kinases, examining their activation levels (PALs) based on transcriptomic data and their associations with survival and drug responsiveness across various cancer types.

Department of Nuclear Medicine, Peking University Cancer Hospital & Institute, Beijing, China.
Background: B7-H3 or CD276 is notably overexpressed in various malignant tumor cells in humans, with extremely high expression rates. The development of a radiotracer that targets B7-H3 may provide a universal tumor-specific imaging agent and allow the noninvasive assessment of the whole-body distribution of B7-H3-expressing lesions.
Methods: We enhanced and optimized the structure of an affibody (ABY) that targets B7-H3 to create the radiolabeled radiotracer [68Ga]Ga-B7H3-BCH, and then, we conducted both foundational experiments and clinical translational studies.

Case: Wide resection of a synovial sarcoma of the anteromedial distal leg involving the dimetaphyseal tibia and posterior tibial tendon produced an 8.5-cm osseous defect. To keep the free flap from invaginating into the defect and prevent kinking of the anastomosis, six 1.
