Background: Patients with cancer showed a high incidence of venous thromboembolism (VTE) with a poor prognosis. The risk factors for VTE in different types of cancers may differ. Methods: The clinical features and laboratory test results of cancer patients with VTE in Henan Provincial People's Hospital from 2014 to 2020 were evaluated and compared. Results: Among the eligible patients, gastrointestinal cancer (GI cancer), lung cancer and gynecological cancer accounted for the top three. This study included 49 patients with GI cancer, 31 with lung cancer and 31 with gynecological cancer. The proportion of patients who underwent surgery in GI cancer or gynecological cancer group was significantly higher than that for lung cancer (69.4% and 80.6% vs 12.9%, both P<0.001). Red blood cell (RBC) and hemoglobin (HGB) levels were lower in the gynecological cancer group than that in the lung cancer group (P = 0.014 and 0.029, respectively), while red cell distribution width (RDW) was higher in the GI cancer group than that in the lung cancer group and gynecological cancer group (P = 0.047 and 0.010, respectively). Prothrom bin time (PT) was shorter in the gynecological cancer group than that in the GI and lung cancer group (P = 0.003 and P = 0.002, respectively). The activated partial thromboplastin time (APTT) in the lung cancer group was longer than that in the GI and gynecological cancer group (P = 0.029 and 0.003, respectively). There was no difference in LOS and successful treatment rate among the groups. However, the VTE cure rate in the gynecological cancer group is higher than that in the GI cancer group (90.3% vs 61.2%, P = 0.005). The probability of continuing to take anticoagulants after discharge in the gynecological cancer group is lower than that in the GI and lung cancer groups (6.5% vs 30.6% and 32.3%, P = 0.011 and 0.022 respectively). Conclusion: VTE risk factors of different types of cancers and laboratory test results were not exactly the same. Thrombosis prevention and treatment should be implemented according to the characteristics of the different types of cancer.
