The urokinase plasminogen activation system in gastroesophageal cancer: A systematic review and meta-analysis.

ABSTRACT:

Background

The urokinase plasminogen activation (uPA) system is a crucial pathway for tumour invasion and establishment of metastasis. Although there is good evidence that uPA system expression is a clinically relevant biomarker in some solid tumours, its role in gastroesophageal cancer is uncertain.

Results

We identified 22 studies encompassing 1966 patients which fulfilled the inclusion criteria. uPA, uPAR, or PAI-1 expression is significantly associated with high risk clinicopathological features. High uPA expression is associated with a shorter RFS (HR 1.90 95% 1.16-3.11, p = 0.01) and OS (HR 2.21 95% CI 1.74-2.80, p < 0.0001). High uPAR expression is associated with poorer OS (HR 2.21 95%CI 1.82-2.69, p < 0.0001). High PAI-1 expression is associated with shorter RFS (HR
