C-reactive protein as a diagnostic and prognostic factor of endometrial cancer

Endometrial cancer (EC) is the sixth most commonly occurring cancer in women and its morbidity and mortality are continuously increasing. Considering experience with different types of cancers, C-reactive protein (CRP) appears to be a promising diagnostic and prognostic factor. Aiming to investigate its potential in view of EC authors of this paper reviewed databases for metanalysis, randomized controlled trials and review articles. Studies indicate CRP > 3.33 mg/l correlates with the EC incidence with HR = 2.29 (p < 0.05). Moreover, High-sensitivity CRP assay allows to detect CRP in very low concentrations and distinguish patients with endometriosis, soft tissue sarcomas and possibly EC. Perioperational CRP, as well as its changes are independent prognostic factors for EC. However, CRP-to-albumin ratio as well as Glasgow Prognostic Score (GPS) have greater prognostic value that CRP alone. Additionally, CRP is possibly a mediator of carcinogenesis and cancer progression through activation of inter alia FcgRs/MAPK/ERK, FcgRs/IL-6/AKT/STAT3 and FcgRs/NF-κB/NLRP3 pathways.
