Meta-analysis indicating that high ALCAM expression predicts poor prognosis in colorectal cancer

چکیده
Activated leukocyte cell adhesion molecule (ALCAM) has been linked to the development and progress of colorectal cancer (CRC). In this meta-analysis, we examined whether ALCAM expression is predictive of survival outcomes in CRC patients. We included 7 studies with 2048 patients in our meta-analysis after searching the PubMed, Cochrane Library, EMBASE, OVID and Web of Science databases. High ALCAM expression was associated with poor overall survival among CRC patients (HR = 1.94, 95%CI = 1.05-3.58, P = 0.03). High ALCAM expression was also associated with aggressive clinicopathological features such as tumor stage (T3,T4/T1,T2; HR = 2.66, 95%CI = 2.01-3.51, P < 0.00001), nodal status (Positive/Negative, HR = 2.12, 95%CI = 1.61-2.82, P < 0.00001), distant metastasis (M1/M0, HR = 3.30, 95%CI = 2,21-4.91, P < 0.00001), tumor grade (grade3/grade1,2, HR = 1,28, 95% CI = 1.00-1.62, P = 0.05), and patient age (> 60/< 60, HR = 1.29, 95%CI = 1.01-1.66, P = 0.05). These findings indicate that high ALCAM expression is associated with poor prognosis and advanced clinicopathological characteristics in CRC patients.

Role of Frizzled receptor expression on patients’ survival with gastrointestinal cancers: A systematic review with meta-analysis
Background: Frizzled receptors (FZD) play a pivotal role in the initiation and progression of a wide array of cancers. Dysregulated expression of FZD receptors is correlated with higher metastasis and invasive potential, as well as short survival in many malignancies. In this meta-analysis, we aimed to verify the prognostic value of FZD receptor expression on patients’ survival with different t...
متن کاملElevated ALCAM shedding in colorectal cancer correlates with poor patient outcome.
Molecular biomarkers of cancer are needed to assist histologic staging in the selection of treatment, outcome risk stratification, and patient prognosis. This is particularly important for patients with early-stage disease. We show that shedding of the extracellular domain of activated leukocyte cell adhesion molecule (ALCAM) is prognostic for outcome in patients with colorectal cancer (CRC). P...
