  Purpose

The duration of anticoagulant treatment in cancer patients with Deep Vein Thrombosis (DVT) of the lower limbs is still uncertain. The present study addresses the possible role of the Residual Vein Thrombosis (RVT) for establishing the optimal duration of Low Molecular Weight Heparin (LMWH). Patients with a first episode of symptomatic unprovoked or provoked proximal DVT will received LMWHs for 6 months; RVT, ultrasonographically-detected, will be then assessed. Patients without RVT stop LMWH, whereas those with RVT will be randomized to either stop or continue OAT for additional 6 months. Patients were followed-up at least 1 year after anticoagulant discontinuation focusing on the study outcomes: occurrence of recurrent venous thromboembolism and major bleeding

Primary Outcome Measures:
  • Recurrent Deep Vein Thrombosis and/or Pulmonary Embolism [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Minor bleeding [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Death due to cancer [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 300
Study Start Date: March 2005
Estimated Study Completion Date: March 2011
Estimated Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: low molecular weight heparin
    LMWH were continued for additional 6 months after detection of residual vein thrombosis (6 months after the index deep vein thrombosis) in patients randomized to group A. LMWH are stopped in patients randomized to group B or in those patients without residual vein thrombosis after 6 months from the index DVT. Dosage of LMWH are 75% of the therapeutic dosage (almost 1 mg/Kg every 12 hours)
