Arterial Thromboembolism in Japanese Patients With Cancer
- Retrospective cohort study
- multicentre
- registry-linked administrative data
Authors' conclusion
The risk for ATE varies according to sex, age, and cancer progression and type. Antithrombotic therapy after ATE is associated with improved survival among patients with cancer.
Study context
- Population
- Patients with cancer, Osaka Cancer Registry linked with administrative data, 2010–201542.3% women, median age 70
- Participants
- 97,448 patients
- Exposure
- Antithrombotic therapy vs none after arterial thromboembolism (ATE)
- Outcome
- Incidence of ATE, with death as a competing risk
- Follow-up
- 5 years after cancer diagnosis

|---|---|---|---|
| RMST after ATE — Antithrombotic therapy vs No antithrombotic therapy · 90-day | 13.3 (10.4–16.2) | P < 0.001 | |
| RMST after ATE — Antithrombotic therapy vs No antithrombotic therapy · 1-year | 57.8 (43.1–72.5) | P < 0.001 | |

Predictors of ATE
- Male sex, advanced age, advanced cancer stage and hematologic malignancies correlated with high ATE risk
Mortality, ATE vs no ATE
- 2-fold increased risk for mortality with ATE
Restricted mean survival time (RMST) after ATE
- RMST differences varied by cancer stage
