Introduction: Thromboprophylaxis recommendations for hospitalized cancer are based on trials done for the general medically patients, as there are no randomized clinical trials(RCTs) looking at thromboprophylaxis in medically ill patients with cancer. Methods: To determine if thromboprophylaxis is safe and effective to prevent VTE these patients, a Systematic Review(SR) was done. A survey was performed to assess: clinical equipoise, trial design and minimally clinically important difference(MCID) for a potential trial. Lastly, a pilot study for an RCT was designed. Results: The pooled RR of VTE was 0.91 (95%CI:0.21 to 4.0;I2:68%) among hospitalized cancer patients receiving thromboprophylaxis compared to placebo. 63.9% believe there is clinical equipoise and 58.3% would consider participating in a RCT comparing different agents/dosing. The MCID for absolute reduction in symptomatic VTE between two arms was 2% and for “acceptable” increase in major bleeding events was 1%. Conclusion: The risk-benefit ratio of current doses of thromboprophylaxis administered to hospitalized cancer patients is unclear and additional RCTs are necessary.
