Summary. Patients with acute venous thromboembolism have an increased risk for occult malignancy. Limited screening for these malignancies has become common practice but little is known about its usefulness. This is a prospective cohort follow‐up study in consecutive patients with acute venous thromboembolism. All patients underwent a routine clinical evaluation for malignancy, if negative, followed by a limited diagnostic work‐up consisting of abdominal and pelvic ultrasound and laboratory markers for malignancy. Clinical follow‐up was conducted to detect screening failures. The routine clinical evaluation was performed in 864 patients and revealed malignancy in 34 (3.9%) of them. Among the remaining 830 patients the limited diagnostic work‐up revealed 13 further malignancies. During follow‐up, cancer became symptomatic in 14 patients who were negative for cancer at screening (sensitivity of limited diagnostic work‐up, 48.1%). Malignancies that were identified by the limited diagnostic work‐up were early stage in 61% of cases vs. 14% in cases occurring during follow‐up. Most patients with occult cancer had idiopathic venous thromboembolism and were older than 70 years. A limited diagnostic work‐up for occult cancer in patients with venous thromboembolism has the capacity to identify approximately one‐half of the malignancies. Identified malignancies were predominantly in an early stage.
