For the radiologist, calcifications in an abdominal malignancy raise questions of both diagnostic and prognostic significance. Although certain cancers are well known to calcify, such as colorectal and ovarian, malignant abdominal calcifications actually arise from a wide variety of epithelial, mesenchymal, lymphoid, or germ cell neoplasms. The pathophysiology of calcification in abdominal malignancies is heterogeneous and incompletely understood. Calcifications may present primarily, in untreated tumors, or develop during treatment; the latter can occur in variable clinical settings. A basic understanding of the varied pathogenic etiology can assist the radiologist in assessing disease status. By presenting an assortment of calcified abdominal malignancies on computed tomography in varied clinical settings, we aim not only to inform the differential diagnosis, but also to clarify the prognosis of calcifications in abdominal malignancies.

Background: Immune checkpoint inhibitors (ICIs) show optimal treatment effects on recurrent or metastatic nasopharyngeal carcinoma(R/M NPC). Nonetheless, whether metastatic sites impact ICIs efficacy remains unclear.
Methods: We performed a secondary analysis of R/M NPC patients treated with KL-A167, a programmed cell death-ligand 1(PD-L1) inhibitor, based on a multicenter, single-arm, phase II study from China between 2019 and 2021 years, which represents the first and most comprehensive analysis of the effectiveness of a PD-L1 inhibitor in patients who have been previously treated.

Introduction: AIM: The aim of the study is to determine the optimal timing for surgery in patients with small bowel duplications.
Methods: A retrospective cohort study, including all patients younger than 18 years who were diagnosed with small bowel duplications from 2013 until 2024 in a single tertiary medical center, was performed. Patients' demographics, duplication size and location, pathological results, and clinical outcomes were collected.

Background: Because the occurrence of metabolic syndrome (MetS) might contribute to childhood cancer survivor's excess risk of cardiovascular disease, the authors assessed the prevalence and determinants of MetS in the Dutch Childhood Cancer Survivor Study (DCCSS-LATER2) cohort.
Methods: In total, 2338 adult childhood cancer survivors (CCS) were cross-sectionally assessed for the prevalence of MetS, using the Lifelines cohort (N = 132,226 adults without a history of cancer) as references. The prevalence of MetS was clinically assessed using existing classifications, as well as an alternative method using dual-energy x-ray absorptiometry fat% instead of waist circumference to define abdominal adiposity.

Background: Systemic light chain amyloidosis is a rare and debilitating disease, especially for which initially presented with digestive tract involvement. Myocardial amyloidosis is highly aggressive with generally poor prognosis and often resulted in missed diagnosis or misdiagnosis with routine examination tools. Multimodality imaging play an important role in diagnosing the amyloidosis effect on multiple organs.

The transport of drugs into tumor cells near the center of the tumor is known to be severely hindered due to the high interstitial pressure and poor vascularization. The aim of this work is to investigate the possibility to induce acoustic streaming in a tumor. Two tumor cases (breast and abdomen) are simulated to find the acoustic streaming and temperature rise, while varying the focused ultrasound transducer radius, frequency, and power for a constant duty cycle (1%).
