Conditions

Venous thromboembolism

Interventions

VTE patients receive the NHI-covered standard rivaroxaban treatment (30 mg/day for 3 weeks after initiation of treatment, followed by 15 mg/day).

Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: Patients aged 20 to 75 years, with active cancer at diagnosis with VTE. Active cancer at baseline was defined as a diagnosis of cancer that occurred within 6 months before enrollment, any treatment for cancer within the previous 6 months, or recurrent or metastatic cancer.

Exclusion criteria

Exclusion criteria: Patients contraindicated for rivaroxaban, with creatinine clearance <30 mL/min, with isolated distal DVT, within 6 months in the remaining days, with a vitamin K antagonist, with severe complication (significant liver disease, active bleeding or a high risk of bleeding contraindicating anticoagulant treatment, severe hypertension (a systolic blood pressure of more than 180 mm Hg or a diastolic blood pressure of more than 110 mm Hg)), pregnancy, and breast-feeding. Patients who the physician in charge judges are ineligible for the present study.

Design outcomes

Primary

MeasureTime frame
Clot regression evaluated by contrast-enhanced CT imaging (Imaging is performed at baseline, 3 weeks and 3 months days after initiation of treatment).The ratio of clot volume regression after 3 weeks or 3 months compared with the clot volume at baseline is investigated. In addition, the rate of normalization (no thrombus in legs and lungs) is also investigated.

Secondary

MeasureTime frame
1)Recurrence of symptomatic DVT or PE 2)Hemorrhagic complications Major bleeding:Clinically definite reduction in Hb by 2.0 g/dL or more, Bleeding requiring 2 units or more of transfusion, Intracranial hemorrhage, retroperitoneal hemorrhage, and bleeding to death Non-major bleeding: Bleeding clinically associated with rivaroxaban not meeting the criteria for major bleeding
