Prognostic significance of 8-hydroxy-2'-deoxyguanosine in solid tumors: a meta-analysis.

ABSTRACT: BACKGROUND:High level of reactive oxygen species (ROS) has been detected in almost all cancers, which make it become one of the best-characterized phenotypes in cancers. Though ROS plays an important role in tumors, the degree of oxidative stress can be better evaluated by assessing stable metabolites of oxidative reactions because of its high instability. 8-hydroxy-2'-deoxyguanosine (8-OHdG), a product of oxidative damage to 2'-deoxyguanosine, is known as a useful marker for assessing oxidative DNA damage and has been a feature of carcinogenesis in several researches. But the exact prognostic value of 8-OHdG expression in patients with cancer is still unclear. METHODS:A comprehensive search was performed in PubMed, Web of Science, EMBASE. Eligible studies were included based on defined ex
