To investigate the role of immunotherapy in the overall survival (OS) of gastrointestinal cancer patients who have liver metastases at the time of the primary site cancer diagnosis. Survival outcome was compared between groups with immunotherapy and groups without immunotherapy. Chemoimmunotherapy was associated with improved OS (hazard ratio [HR] 0.

Methods: A retrospective study was conducted involving 179 lung cancer patients treated with SBRT at the University of Nebraska Medical Center (UNMC) between October 2007 and June 2022. Features from the CT image, Biological Effective Dose (BED) and five interaction matrices between CT and BED were extracted using radiomics mathematics.
The diagnosis and treatment of sinonasal small round epithelial/neuroepithelial malignancies depend on the expression of conventional neuroendocrine markers (NEMs), such as synaptophysin, chromogranin A, INSM1, and CD56/NCAM1. However, these tumors remain diagnostically challenging because of overlapping histologic and immunohistochemical features. The transcriptional regulators ASCL1, NEUROD1, POU2F3, and YAP1 are novel NEM (nNEM) used for the subtyping of small-cell lung cancer (SCLC).
