Carcinoembryonic antigen (CEA) is among the earliest identified tumor markers and remains extensively utilized in the diagnosis and management of colorectal cancer. The detection of CEA presents considerable challenges in the field of analytical chemistry, given its complexity. The most prevalent detection approach is the immunoassay, including the chemiluminescence immunoassay commonly employed in clinical settings; however, discrepancies between various methods persist. Mass spectrometry-based techniques offer enhanced accuracy as they circumvent matrix interference. Nonetheless, the intricate nature of proteins continues to pose significant challenges. This paper reviews recent advancements in CEA detection technologies, examines their clinical application potential from two key platforms, and addresses the standardization process of CEA detection. This paper highlights the importance of developing rapid and precise methods for CEA analysis in complex matrices and their standardization.

Unlabelled: Leptomeningeal metastasis (LM) is a severe complication of solid malignancies, including lung adenocarcinoma, characterized by poor prognosis and diagnostic challenges. This study assesses whether curvilinear peri-brainstem hyperintense signals on MRI are a characteristic feature of LM in lung adenocarcinoma patients.
Methods: This retrospective study analyzed data from multiple centers, encompassing lung adenocarcinoma patients with peri-brainstem curvilinear hyperintense signals on MRI between January 2016 and March 2022.

Unlabelled: Autoimmune haemolytic anaemia (AIHA) is caused by antibody-mediated destruction of red blood cells. There are two broad categories of AIHA: warm and cold, both categorized by the thermal reactivity of the autoantibodies. Cold agglutinin disease (CAD) occurs at temperatures below normal body temperature and primarily involves IgM antibodies.

Objective: The retrieval of 12 lymph nodes (LNs) remains a crucial criterion for accurate staging and prognosis evaluation in rectal cancer (RC). However, some patients fail to meet this threshold after surgery. This study developed a nomogram model based on clinical variables to predict the probability of retrieving 12 LNs postoperatively.

Objectives: Lymph node metastasis (LNM) is an important factor affecting the stage and prognosis of patients with lung adenocarcinoma. The purpose of this study is to explore the predictive value of the stacking ensemble learning model based on F-FDG PET/CT radiomic features and clinical risk factors for LNM in lung adenocarcinoma, and elucidate the biological basis of predictive features through pathological analysis.
Methods: Ninety patients diagnosed with lung adenocarcinoma who underwent PET/CT were retrospectively analyzed and randomly divided into the training and testing sets in a 7:3 ratio.

Steroid-refractory gut acute graft-versus-host disease (SR-Gut-aGVHD) is the major cause of nonrelapse death after allogeneic hematopoietic cell transplantation. High numbers of donor-type IL-22+ T cells, IL-22-dependent dysbiosis, and loss of antiinflammatory CX3CR1hi mononuclear phagocytes (MNPs) play critical roles in SR-Gut-aGVHD pathogenesis. CEACAM1 on intestinal epithelial cells (IECs) is proposed to regulate bacterial translocation and subsequent immune responses in the intestine.
