Prevalence and incidence of deep venous thrombosis and pulmonary embolism in 2 regions in Turkey (A sub-analysis of CAT-TR study)

Aim: Venous thromboembolism (VTE) is a relatively common public health problem. In addition to increasing mortality due to complications, it also causes an increase in the cost of the country's economy and loss of labor due to the morbidity it creates. Considering that the recurrence of VTE is a common condition, the importance of this disease for the society increases even more. Although we have come a long way in treatment and follow-up, we see that VTE and its related complications maintain their place as a significant risk factor in the society at increasing rates. Material and Methods: This is an additional analysis of a multicentral, retrospective descriptive study, CAT-TR (Assessment of Patient Characteristic in Cancer Associated Venous Thrombosis in Turkey). The aim of the CAT-TR study was to evaluate patient characteristic and treatment patterns of cancer-induced VTE in Turkey. This article aims to evaluate the incidence and prevalence of cancer-induced VTE in two regions of Turkey between January 01, 2016 and December 31, 2019. Results: In our study, the 4-year prevalence of Deep Venous Thrombosis (DVT) and Pulmonary Embolism (PE) in Central Anatolia and Marmara was 86.43, 103.56 and 105.68, 98.04 per 100.000 people, respectively. The cumulative incidence of cancer-related VTE in the Central Anatolian and Marmara populations is 17.22 and 6.71 per 100.000 people, respectively. Conclusion: The values we found in the prevalence and incidence study of VTE will be very valuable in terms of being a reference for us in the treatment and prevention of the disease. We believe that this study will shed light on new studies for diseases that may cause VTE in larger populations and strategies to be followed in prevention.
