Abstract
Purpose
Venous thromboembolism (VTE) is a major complication of cancer with recent increasing reports of incidental VTE. The objectives are to estimate the prevalence of incidental VTE in cancer patients on staging CT scans, identify common symptoms, and determine VTE recurrence in a prospective study.
Patients and methods
One thousand ninety patients were studied. Adult cancer patients scheduled for outpatient staging CT scans were eligible. VTE cases were followed for 6 months. Fisher’s exact test for group comparisons of categorical variables and generalized linear modeling to estimate the prevalence of incidental VTE was used.
Results
The mean age was 58 years (range 18–87 years); 50% were male. The prevalence of incidental VTE was 1.8% (CI 1.15–2.87%). Significant symptoms in patients with VTE included fatigue (p = 0.004), stress (p = 0.0195), depression (p = 0.019), poorer quality of life (p = 0.0194), and poorer physical well-being (p = 0.0007). All the patients with VTE had at least one comorbidity (p = 0.03). No patient had recurrence within 6 months.
Conclusion
The prevalence of incidental VTE on staging CT scans is lower than previously reported. Symptoms were associated with VTE; however, further work is needed to understand whether these are clinically relevant. No VTE recurrences were noted following 6 months.
