Chest radiography as a method of screening for occult cancer in patients with idiopathic deep vein thrombosis.

The occurrence of neoplasms in patients with idiopathic deep vein thrombosis (DVT) may result in a significant reduction in survival rates. The aim of our study was to assess the use of chest X-rays (CXRs) as a screening method of intrathoracic neoplasms in patients who with idiopathic DVT. In observational, cross-sectional study, the medical records of 99 patients with idiopathic DVT, who were submitted to CXR (during the hospital stay or within 30 days after discharge), were investigated.
