The value of the serum level of carcinoembryonic antigen (CEA) as an indicator of recurrent colorectal carcinoma has been accepted, and the use of serial CEA levels to monitor postoperative chemotherapy has been suggested, However, elevated CEA levels may be associated with nonneoplastic conditions, of which the most difficult to evaluate is hepatic disease. The effect of chemotherapy on hepatic function and therefore on CEA level is not clear. We discuss a patient who, after a potentially curative resection for adenocarcinoma, demonstrated a rise in CEA level in the absence of recurrent carcinoma. This rise correlated with administration of intravenous 5-fluorouracil. Liver biopsy demonstrated severe fatty infiltration with no evidence of cirrhosis. The possible liver toxicity of chemotherapeutic drugs must be considered as a factor responsible for the rise in CEA. Simultaneous assessment of hepatic function is essential to the accurate interpretation of CEA levels, especially in patients receiving chemotherapy.

: Developing ex vivo models that replicate immune-tumor interactions with high fidelity is essential for advancing immunotherapy research, as traditional two-dimensional in vitro systems often lack the complexity required to fully represent these interactions. : In this study, we establish a comprehensive 3D redirect lysis (3D-RDL) assay using colorectal cancer spheroids and adult stem cell-derived, healthy human organoids to evaluate the efficacy and safety profile of , a bispecific antibody targeting carcinoembryonic antigens (CEAs) on cancer cells and CD3 on T cells. This model allows us to assess cytotoxic activity and immune responses, capturing variations in therapeutic response not observable in simpler systems.

Objective: Urinary proteins are effective tumor biomarkers. Human epididymis protein 4 (HE4), progastrin-releasing peptide (ProGRP), carcinoembryonic antigen (CEA), cytokeratin-19 fragment 21-1(CYFRA 21-1), and neuron-specific enolase (NSE) in serum, were proposed as tumor biomarkers of lung cancer. Our aim was to identify the urine protein biomarkers that can distinguish patients with lung cancer from healthy individuals and/or patients with benign lung disease with a high level of sensitivity and specificity.

Within the ITER project (International Thermonuclear Experimental Reactor) an international project building a magnetic confinement device to achieve fusion as a sustainable energy source, tungsten (W) is planned to serve as a plasma-facing component (PFC) in the tokamak, a magnetic confinement device used to produce controlled thermonuclear fusion power. Post plasma-W interactions, submicron tungsten particles can be released. This study investigated the exposure of lentic freshwater ecosystems to ITER-like tungsten nanoparticles in indoor aquatic mesocosms.

Background: Thoracic SMARCA4-deficient undifferentiated tumors (SMARCA4-UT) exhibit a notably aggressive phenotype, which is associated with poor patient survival outcomes. These tumors are generally resistant to conventional cytotoxic chemotherapy, thereby limiting the availability of effective treatment options.
Case Presentation: We describe a 69-year-old AIDS patient who initially presented with a fused, enlarged lymph node on the right clavicle and mild, unexplained pain under the right axilla that worsened with severe coughing episodes.
Long term outcomes associated with the use of perioperative systemic chemotherapy on low grade appendiceal mucinous neoplasms with pseudomyxoma peritonei treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Introduction: Low grade appendiceal mucinous neoplasms (LAMN) are indolent tumors that lack invasive potential but may present as pseudomyxoma peritonei. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) significantly improves both overall and recurrence free survival. While systemic chemotherapy is generally considered ineffective for LAMN, little literature is available to support this notion.
