<qa>  What is the proposed pilot project?The proposed pilot project is a multicenter blinded placebo-controlled randomized controlled pilot clinical trial assessing the feasibility and effectiveness of extended-duration VTE prophylaxis 30 days post-operatively vs. short-term prophylaxis restricted to in-hospital stay with outpatient injected placebo, in patients undergoing lung resection for lung cancer or metastatic disease. All patients will receive both a peri-operative dose followed by postoperative VTE prophylaxis for the duration of their hospital stay. Those who were randomized to prolonged prophylaxis will continue the same dosage regime for an overall of 30 days, whereas the control group will receive placebo injections for the same duration of time.
