Ectopic Corticotropin-Releasing Hormone-Secreting Pancreatic Neuroendocrine Tumor: Excellent Response of Liver Metastases to Peptide Receptor Radionuclide Therapy as Demonstrated by 68Ga-DOTATOC and 18F-FDG PET/CT Imaging.
Herein, we present the case of a 49-year-old man with pancreatoblastoma and liver metastasis who underwent preoperative multimodal imaging, in which F-FDG PET/CT showed a markedly increased F-FDG uptake in the metastatic lesion and a slightly increased uptake in the primary lesion.
The relationship between these two signaling pathways remains to be delineated in liver metastasis of colon cancer.<b>Methods</b>: Immunohistochemistry was employed to investigate CXCR4 expression in 45 human specimens of primary colorectal cancer (CRC) and liver metastasis.
Evaluation of [<sup>18</sup>F]FDG/[<sup>18</sup>F]FLT/[<sup>18</sup>F]FMISO-based micro-positron emission tomography in detection of liver metastasis in human colorectal cancer.
Left-sided tumors with wild-type KRAS had greater proportion of liver metastasis (78.6% versus 53.5%, P = 0.00), whereas those with mutant KRAS had greater proportion of lung metastasis (23.3% versus 8.7%, P = 0.02).
When treating hormone receptor-positive/HER2-negative MBC patients with endocrine therapy, it is important to differentiate patients with lung metastases from those with liver metastases.
TP53 mutations were studied by Sanger sequencing in the remaining patients; the number of patients with TP53 mutations in metastatic tumors was significantly higher among those with liver metastasis (86.5%, 32/37) versus those without liver metastasis (40.5%; 15/37; P < 0.0001).
Does KRAS mutation status impact the risk of local recurrence after R1 vascular resection for colorectal liver metastasis? An observational cohort study.
ECOG (Eastern Cooperative Oncology Group) performance scores, CEA levels, CA19-9 levels, hemoglobin levels, lactate dehydrogenase levels, and liver metastasis ratios varied significantly between the low and high AGR groups (p < .05).
A decreased overall survival was significantly associated with peritoneal involvement (HR 1.944; p = 0.003), ascites (HR 2.055; p = 0.034), synchronous presentation (HR 1.679; p = 0.034) and increased serum CEA levels (HR 1.380; p = 0.010), but not with age > 50 (HR 0.946; p = 0.743), menopausal status (HR 1.565; p = 0.204), gastric origin (HR 1.600; p = 0.201), size > 5 cm (HR 1.292; p = 0.119), size > 10 cm (HR 0.925; p = 0.714), bilateral ovarian involvement (HR 1.113; p = 0.347), non-peritoneal extaovarian metastases (HR 1.648; p = 0.237), liver metastases (HR 1.118, p = 0.555), predominant signet ring cell morphology (HR 1.322; p = 0.208) and levels of CA125 (HR 0.933; p = 0.828) and CA19.9 (HR 0.996; p = 0.992).
After HA receptor (CD44)-mediated cellular uptake of the HTsRP-NC by the liver cancer cells, functional expression of AKT siRNA leads to the suppression of metastatic liver cancer growth in a colorectal liver metastasis (CLM) murine model.
Prognostic impact of K-RAS mutational status and primary tumor location in patients undergoing resection for colorectal cancer liver metastases: an update.
ECOG (Eastern Cooperative Oncology Group) performance scores, CEA levels, CA19-9 levels, hemoglobin levels, lactate dehydrogenase levels, and liver metastasis ratios varied significantly between the low and high AGR groups (p < .05).
In conclusion, targeting CBP/β-catenin, combined with PD-1/PD-L1 immune checkpoint blockade, shows potential as a new therapeutic strategy for treating liver metastasis during colon cancer.
ECOG (Eastern Cooperative Oncology Group) performance scores, CEA levels, CA19-9 levels, hemoglobin levels, lactate dehydrogenase levels, and liver metastasis ratios varied significantly between the low and high AGR groups (p < .05).
