The objectives of this study were to establish the prevalence of DVT in cancer patients at KNH medical and oncology wards, to describe patient characteristics of those with DVT vs those without and compare rates of DVT in different types of cancer. This was a cross-sectional descriptive study carried out at the Kenyatta National Hospital general medical wards and oncology wards. Patients were interviewed and examined. Patients’ records were perused for information relevant to the study. Patients with history and physical examination findings suggestive of a thrombotic event were screened by compression sonography to confirm a DVT. A total of 266 patients with a diagnosis of cancer were studied, 29 (10.9%) had DVT. Among the patients who were found to have DVT, 13 (44.8%) had gynaecological cancers, 3 (10.3%) breast cancer, 3(10.3%) prostate cancer, 3(10.3%) gastric cancer, 2(6.9%) patients had lymphoma and a patient (3.4%) each in the multiple myeloma, adenocarcinoma, squamous cell carcinoma and pancreatic cancer groups. Some significant patient characteristics in the patients who had a DVT were female sex (P value 0.014), presence of comorbidities (P 0.004) and ECOG scores of 3 and 4 (P 0.04, 0.001). Some common risk factors known for DVT were analysed and some were found to be significant in our patient group. Of the significant risk factors,
presence of comorbid condition, female sex and higher ECOG scores were noted. Keywords: DVT, VTE, ECOG, Comorbidities, Kenyatta National Hospital
Venous thromboembolic events in cancer are quite common and are a leading cause of morbidity, delays in care and death. As cancer is a heterogeneous disease, the risk of DVT depends on cancer types and stages, treatment
measures, and patient-related factors
