Incidence of Venous Thromboembolism Following Surgery in Patients With Colorectal Cancer
Incidence of Venous Thromboembolism Following Surgery in Korean Patients With Colorectal Cancer; a Prospective Study
Venous thromboembolism (VTE) has harmful effects on morbidity and mortality of cancer patients. In Western VTE guidelines, all solid cancer patients receiving abdominal major surgery are strongly recommended to receive pharmacologic prophylactic anticoagulation such as low molecular weight heparin (LMWH) in the perioperative periods. These recommendations are based on the high incidence of postoperative VTE development in Western cancer patients. However, there have been many cumulative data about the effect of different ethnicity on the VTE development and more and more investigators and clinicians admit that Asian ethnicity has lower incidence of VTE than Western ethnicity. Therefore, it may not be advisable to apply Western guidelines as it is to the clinical situation of Asian cancer patients.
Although colorectal cancer (CRC) is one of the common cancers and the incidence is rapidly increasing in Asia, there have been few prospective data on the incidence of VTE development during the postoperative period in Asian CRC patients. To our knowledge, there have been a few small-sized prospective studies in Asia and thus clear conclusions could have not been drawn based on those studies. Most Korean colorectal surgeons think that the incidence of postoperative VTE development is very rare based on their own clinical experiences. They also have much concern about the complications such as bleeding that might be caused by routine use of pharmacologic thromboprophylaxis during the perioperative periods. Therefore, in most clinical situation, many Korean colorectal surgeons do not perform perioperative pharmacologic thromboprophylaxis using LMHW. Considering these clinical situations in Asia including Korea, the uncritical acceptance of Western guidelines may be inappropriate. The necessity of pharmacologic thrombo-prophylaxis can be answered only from our own prospective study on the incidence of postoperative VTE development after CRC surgery. Moreover, current surgical trend in cancer patients is minimally invasive approach such as laparoscopic surgery. However, the necessity of pharmacologic thromboprophylaxis in patients receiving laparoscopic cancer surgery has not been evaluated even in Western countries. Western guidelines also cannot exactly answer whether pharmacologic thromboprophylaxis is really necessary in cancer patients receiving laparoscopic cancer surgery. On above backgrounds, this study was designed.

Intervention / Behandling |
---|---|
Group A
Patients who gave a permission to this study and underwent doppler US (Doppler US cohort - Expected subject no.: 400 patients |
Patients will receive surgery for the treatment of CRC as routine clinical practice. These patients will be prospectively observed for the development of VTE(Group A; Doppler US cohort vs. Group B; Simple observation cohort) - Doppler US is not an intervention. The Doppler US is a non-invasive test (ultrasonography) for the detection of VTE |
Group B
Patient who gave a permission to this study, but who did not receive doppler US (Although this group of patients did not undergo doppler US, these patients will be included as group B [simple observation cohort without doppler US examination]) - Expected subject no.: 200 patients |
