Key result
Primary deep venous thrombosis was associated with a 2.65% incidence of subsequent cancer compared to 0% in secondary DVT, suggesting routine screening with expensive modalities is not supported.
Why the study?
Does deep vein thrombosis predict the subsequent development of cancer?

196 patients with confirmed venous thrombosis treated over a seven-year period

Low cancer incidence after DVT does not support routine screening; leaves open targeted vigilance in primary cases.
Cohort (n=196)
Does deep vein thrombosis predict the subsequent development of cancer?
Absolute Event Rate: 2.65% vs 0%
The low overall incidence of subsequent cancer (1.53%) in DVT patients does not support routine extensive screening for occult malignancy, though vigilance is warranted in primary DVT.
Ahmed et al. (1996) conducted a cohort in Deep venous thrombosis (n=196). Primary type deep venous thrombosis vs. Secondary type deep venous thrombosis was evaluated on Subsequent development of cancer. Primary deep venous thrombosis was associated with a 2.65% incidence of subsequent cancer compared to 0% in secondary DVT, suggesting routine screening with expensive modalities is not supported.
