Potential clinical utility of plasma D-dimer levels among women with cervical cancer in Lagos, Nigeria

Résumé

The link between plasma D-dimer levels and underlying malignancy has been established.How this translates in clinical practice as a marker of detection and prognosis of cervical cancer (CC) is still unknown.This study compared the plasma D-dimer levels in women with and without CC and assessed the associations between plasma D-dimer levels and the stage and grade of CC.It was a comparative cross-sectional study of 65 women with histological diagnosis of CC and an equal number of age-matched cancer-free women enrolled at the University Teaching Hospital in Lagos, Nigeria.Participants' sociodemographic and clinical data as well as venous blood samples for estimation of plasma D-dimer were collected for statistical analyses.A receiver operating characteristic (ROC) analysis is performed to select the cut-off value of plasma D-dimer for differentiating CC from non-cancer.There was a statistically significant difference in the median levels of plasma D-dimer of women with CC and their cancer-free comparison groups (3,120 (1,189-4,515) versus 210 (125-350) ng/mL; p = 0.001).A plasma D-dimer value of 543 ng/mL was chosen in a ROC analysis as the discriminatory cut-off to differentiate CC from non-cancer.There were significant associations between plasma D-dimer levels and the International Federation of Gynaecology and Obstetrics stage (p = 0.001) or grade (p = 0.001) of CC.The study, therefore, demonstrated the potential clinical usefulness of plasma D-dimer as a diagnostic and prognostic marker of CC.
