Cancer patients are at high risk of thromboembolic complications (deep vein thrombosis, pulmonary embolism) which increase the morbidity and mortality rates. Τhe thromboembolic risk is further increased perioperatively in cancer surgery, rendering its prevention and management a clinical challenge. International Societies and Experts’ Panels have addressed this issue in an effort to fill in the existing gaps, since evidence is rather limited.
Thromboprophylaxis should be given to all patients undergoing cancer surgery. It should include pharmacological agents and should be initiated preoperatively and/or as soon as possible postoperatively. Mechanical prophylaxis alone is not recommended, and should be reserved only for cases where pharmacological thromboprophylaxis is contraindicated. Combined pharmacological/mechanical thromboprophylaxis should be used in high risk patients. The patient risk factors, co-morbidities, procedure type/duration and the surgical bleeding risk should be carefully assessed before deciding the scheme, drugs, dosing and timing of thromboprophylaxis. Low Molecular Weight Heparin (is the preferred agent), Unfractionated Heparin (if creatinine clearance <30 mL/min) and possibly Fondaparinux can be used for thromboprophylaxis. There is no consensus on the use of inferior vena cava filters; they are not recommended as a routine thromboprophylactic measure, but their placement could be considered in patients with pulmonary embolism or lower limb proximal deep vein thrombosis (especially during the first 2–4 weeks), if anticoagulants are contraindicated. The risk of intervention-related adverse effects/complications should be taken into account.
Postoperative pharmacological thromboprophylaxis should be maintained for at least 7–10 days. For high risk, major abdominal or pelvic surgery (laparotomy or laparoscopic), thromboprophylaxis should last longer (up to 4 weeks). Patients facing a high risk for both thrombosis and major bleeding should receive mechanical thromboprophylaxis first and pharmacological prophylaxis should be added as soon as possible. Early postoperative ambulation should be encouraged whenever possible.

Science Citation Index Expanded (SciSearch) Created as SCI in 1964, Science Citation Index Expanded now indexes over 9,200 of the world’s most impactful journals across 178 scientific disciplines. More than 53 million records and 1.18 billion cited references date back from 1900 to present.
Journal Citation Reports/Science Edition Journal Citation Reports/Science Edition aims to evaluate a journal’s value from multiple perspectives including the journal impact factor, descriptive data about a journal’s open access content as well as contributing authors, and provide readers a transparent and publisher-neutral data & statistics information about the journal.
Chemical Abstracts Service Source Index The CAS Source Index (CASSI) Search Tool is an online resource that can quickly identify or confirm journal titles and abbreviations for publications indexed by CAS since 1907, including serial and non-serial scientific and technical publications.
Index Copernicus The Index Copernicus International (ICI) Journals database’s is an international indexation database of scientific journals. It covered international scientific journals which divided into general information, contents of individual issues, detailed bibliography (references) sections for every publication, as well as full texts of publications in the form of attached files (optional). For now, there are more than 58,000 scientific journals registered at ICI.
