We discovered that expression of c-Myc was significantly related to distant metastasis, the combined expression of PTEN and p21 correlated positively to overall survival, while p57 was less useful in overall survival prediction in gastric cancer.
In addition, this reduction in p57 expression was associated with increased tumor size, more advanced TNM stages, the presence of capsule invasion and extrahepatic metastasis and decreased overall survival time.
Co-expression of p57 and p-cofilin was reduced in specimens from patients with tumors at later stages (III + IV), tumors showing capsular invasion and metastatic tumors.
