This study plans to learn more about the role of 2 blood tests in predicting who might develop a blood clot in their arm or leg after major surgery. The investigators know that patients who have cancer and major surgery have a higher than normal risk of getting blood clots in the veins of their arms or legs. This can be very dangerous because the clot can move into your lungs.

Condition Intervention
Venous Thromboembolism Other: blood tests

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Predictive Value of Whole Blood Coagulation Parameters for Post-discharge Venous Thromboembolism After Cancer Resection.

Further study details as provided by University of Colorado, Denver:

Primary Outcome Measures:
  • Venous thromboembolism free survival after surgery for gastrointestinal or urologic cancer [ Time Frame: 3 months post-discharge from hospital ]

Enrollment: 4
Study Start Date: November 2012
Study Completion Date: January 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: diagnostic blood tests
We are using 2 standard approved blood tests that may be useful in predicting who may develop a venous thromboembolism after cancer surgery.
Other: blood tests
thromboelastogram platelet mapping

Detailed Description:
Venous Thromboembolism (VTE) after cancer surgery hospitalization is the most common cause of death at 30 days after cancer surgery, and is a significant source of patient morbidity and health care cost. Pharmacoprophylaxis has proven efficacy in preventing post-discharge VTE in surgical cancer patients, but perceived risks and costs pose barriers to widespread adoption by clinicians. Risk stratification of this patient population is necessary to allow appropriate prescription of prophylaxis to the highest risk patients. Can the investigators develop a risk stratification model that includes a readily available laboratory test, the thromboelastogram with or without platelet mapping?
