Summary |
Introduction |
In cancer patients with catheter-associated upper extremity deep vein thrombosis, 3 months of anticoagulation is recommended. The main objective of this study was to compare the incidence of thrombosis recurrence in these patients in case of continuation or discontinuation of anticoagulation, at the end of 3 months and after catheter has been removed. The secondary objectives were the incidence of major bleeding and death.
Material and methods |
We conducted a retrospective cohort study including patients with a cancer and a catheter-associated upper extremity deep vein thrombosis.
Results |
About 60 patients included, 44 stopped anticoagulation after the first 3 months and 16 continued it. The median time between catheter insertion and deep vein thrombosis was 26±83 days. Three recurrences occurred during the one-year follow-up: 2 in the group who stopped anticoagulation, with a cumulative incidence at 1 year of 4,8% (95%IC 1.2–18.1) and 1 in the group who continued anticoagulation, with a cumulative incidence at 1 year of 14.3% (95%IC 2.1–66.6). No major bleeding event occurred in anticoagulation discontinued group. The group who stopped anticoagulation was significantly associated with a lower risk of death (HR 0.21–95%IC 0.09–0.48, P<0.001).
Conclusion |
The risk of recurrence in cancer patients with a catheter-associated upper extremity deep vein thrombosis was low and statistically comparable between the group who stopped anticoagulation and the group who continued it. These results suggest that anticoagulation after the first 3 months deserves to be considered when catheter is removed.
