D-dimer as a potential prognostic marker.

Area of Science:

• Oncology
• Hematology
• Clinical Pathology

Background:

• Malignant tumors increase the risk of thrombosis and embolism.
• D-dimer, a fibrinolysis product, is a marker for these procoagulant activities.

Purpose of the Study:

• To evaluate the prognostic value of D-dimer in cancer patients.
• To assess the association between D-dimer levels, venous thromboembolism (VTE), and cancer progression.

Main Methods:

• Retrospective study of nearly 300 cancer patients.
• Analysis of D-dimer levels during low molecular weight heparin (LMWH) thromboprophylaxis.
• Correlation of D-dimer with VTE frequency, cancer type, stage, and mortality.

Main Results:

• Pancreatic cancer showed the highest VTE frequency and worst prognosis, followed by ovarian, colonic, and breast cancers.
• Increased D-dimer levels correlated significantly with advanced cancer stages and higher mortality rates.
• D-dimer demonstrated prognostic accuracy comparable to or exceeding established tumor markers.

Conclusions:

• D-dimer is a valuable prognostic indicator in cancer patients, particularly for VTE risk.
• Elevated D-dimer levels are associated with disease progression and mortality.
• D-dimer could be utilized as an additional prognostic tool in oncology.
