Questions about Venous Thromboembolism

Does having asthma increase my odds of developing venous thromboembolism or deep vein thrombosis?

Yes, asthma is linked to higher odds of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE).

What factors predict a recurrence of venous thromboembolism or bleeding in adult cancer patients?

In adult cancer patients, prior VTE, poor performance status, advanced cancer, and certain tumor sites (lung, pancreas, hepatobiliary, genitourinary) predict higher recurrence risk; elevated biomarkers like growth differentiation factor-15 also raise risk.
