BACKGROUND: The D-dimer test is a simple test frequently used in routine clinical screening for venous thromboembolism (VTE). The Cancer-VTE Registry was a large-scale, multicenter, prospective, observational study in Japanese patients with cancer. This study aimed to clarify the relationship between D-dimer level at cancer diagnosis (baseline) and the incidence of events during cancer treatment (1-year follow-up period).
METHODS: This was a post hoc sub-analysis of patients from the Cancer-VTE Registry whose D-dimer levels were measured at baseline. The incidence of events during the 1-year follow-up period was evaluated stratified by baseline D-dimer level. Adjusted hazard ratios for D-dimer level and events during the follow-up period were evaluated.
RESULTS: Among the total enrolled patients, baseline D-dimer level was measured in 9020 patients. The mean ± standard deviation baseline D-dimer level was 1.57 ± 3.94 µg/mL. During the follow-up period, the incidence of VTE, cerebral infarction/transient ischemic attack (TIA)/systemic embolic events (SEE), bleeding, and all-cause death increased with increasing baseline D-dimer level. The incidence of all-cause death increased with increasing D-dimer level regardless of cancer stage. The adjusted hazard ratio of all-cause death was 1.03 (95% confidence interval: 1.02-1.03) per 1.0-µg/mL increase in baseline D-dimer level.
CONCLUSIONS: Increases in D-dimer levels were associated with a higher risk of thrombotic events, such as VTE and cerebral infarction/TIA/SEE, during cancer treatment. Furthermore, higher D-dimer levels at cancer diagnosis were associated with a higher mortality rate, regardless of cancer stage.
