Active Cancer Patients Having Cancer Related Invasive Procedures or Surgery and Needing Perioperative Management of Anticoagulation Therapy (ACE-HIGH): A Prospective Management Cohort Study
The purpose of this study is to help find how safe current practices are when managing blood thinners in people with cancer who are having surgery or medical procedures. Investigators will also measure how often bleeding or clotting problems happen in this setting. The goal is to use this information to improve future care and reduce these risks for patients. This study will determine whether contemporary practices can be safely applied to cancer patients, and also evaluate the blood thinner level left over in patient's body at the time of surgery.
• Age ≥ 18 years
• Prescribed a Direct Oral Anticoagulant (DOAC), warfarin (International Normalized Ratio (INR) target 2.0-3.0) or Low Molecular Weight Heparin (LMWH) (75-100% weight-based therapeutic dosing) for stroke prevention in Atrial Fibrillation (AF) or the treatment of Venous Thromboembolism (VTE).

• Has active cancer, defined as:
• i. cancer diagnosed within 6 months ii. recurrent, regionally advanced, or metastatic cancer iii. cancer for which treatment had been administered within 6 months before enrolment iv. hematologic cancer that is not in remission v. Patients who are felt to likely have active cancer based on clinical/imaging characteristics but are awaiting tissue confirmation and are scheduled for a biopsy procedure are eligible for trial inclusion
• Is undergoing a planned cancer-related inpatient or outpatient invasive procedure or cancer surgery (to diagnose, treat or palliate cancer; at investigator's discretion)
• Interruption of anticoagulation therapy for the planned procedure is required.
