The results showed a significant association between overexpression of CD133 and estrogen receptor status (OR 0.35, 95% CI 0.18-0.70), progesterone receptor status (OR 0.56, 95% CI 0.43-0.74), human epidermal growth factor-2 status (OR 1.81, 95% CI 1.33-2.45), lymph node metastasis (OR 1.98, 95% CI 1.34-2.92), and tumor histological grade (OR 1.79, 95% CI 1.26-2.54) in breast cancer.
Lymph node metastasis is strongly associated with expression status of HGF and CD133 at the deep invasive front, suggesting the usefulness of these proteins as independent predictive markers of lymph node metastasis in early gastric cancer.
In young adults, the expression of CD133 was significantly more frequent in patients with tumours >3 cm (p=0.04) and in patients with lymph node metastases (p=0.02).
High level of CD133 expression trends to correlate with a worse prognosis and a higher rate of lymph node metastasis in NSCLC patients, revealing CD133 as a potential pathological prognostic marker for NSCLC patients.
Molecular detection of CEA, CK20 and/or CD133 (CEA/CK20/CD133) mRNA of the peritoneal washings showed a significant correlation with lymph node metastasis and the tumor stage.
Average brightness scale value (BSV) of CD133 mRNA was significantly higher in subgroups with >5 cm diameter (P = 0.041), lymph node metastasis occurrence (P = 0.004) and in lower Ki-67 LI (P = 0.02).
