Condition(s) targeted: Lung Cancer
Intervention: Dalteparin (Fragmin®) (Drug)
Phase: Phase 4
Status: Completed
Sponsored by: Thomas Decker Christensen Official(s) and/or principal investigator(s): Thomas D Christensen, MD, Principal Investigator, Affiliation: Aarhus University Hospital
Summary
The purpose of the study is:
To estimate patients with lung cancers who will undergo surgery total haemostatic /
thrombotic capacity pre, per-and postoperatively.
To investigate whether prophylactic treatment with Low Molecular Weight Heparin (LMWH)
affects the patient's potential hypercoagulability.
To investigate whether there are differences in patients who will undergo Video Assisted
Thorascopic Surgery (VATS) or open surgery in regards of impact of the coagulation system.
Clinical Details
Official title: Coagulation Profile in Patients Undergoing Video Assisted Thorascopic Surgery (VATS) for Lung Cancer - A Randomized, Controlled Trial
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment
Primary outcome: Thromboelastometry (ROTEM®)
Secondary outcome: Thrombin generation
Detailed description:
Lung cancer is a serious and very frequent disease. For those 25% of the patients who will
undergo surgery, there are two different methods of operation: either open surgery
(thoracotomy) or Video Assisted Thorascopic Surgery (VATS). The latter method is increasing
in use.
Patients are often prescribed heparin pre- postoperatively, but it is unclear whether this
prophylactic treatment is necessary, and it has never been thoroughly investigated.
When patients receive heparin there is an increased risk of bleeding.
Furthermore, it is unclear what changes occurs in the coagulation system pre, per- and
postoperatively in patients undergoing surgery for lung-cancer, and hereby it is unclear
whether these patients should have some sort of medical prophylactic treatment.
By using new analysis methods in terms of Thromboelastometry, Thrombin generation and
thrombocyte function analysis, hereby the total coagulation profile can be characterized and
hereby estimate the risk of thrombosis and bleeding. Thereby better be able to give the
right treatment for these patients.
