Outpatient management of incidental pulmonary embolism in cancer patient

Incidentally discovered pulmonary embolism is a prevalent clinical problem for cancer patients and contributes significantly to the burden of cancer-associated thrombosis. The aim of this study was to explore if outpatient management of incidental pulmonary embolism (iPE) in cancer patients is effective and can be conducted safely.

We performed a prospective observational cohort study in a single Spanish tertiary hospital. Patients diagnosed with iPE and active cancer were enrolled. Between May 2016 and May 2017, 25 consecutive patients were included in the study.

All patients were assessed in the emergency room (ER) and started treatment with low-molecular weight heparins (LMWH) being discharged in the following 24 h. Congestive heart failure and right ventricular dysfunction were ruled out, and none of them presented massive PE, active bleeding or any disease-related reason that required hospitalization. The 90-day follow-up visit showed no venous thromboembolism (VTE) recurrence and the major bleeding rate was 4%. Mortality rate at 30 and 90 days was 0%.

Outpatient management for iPE in cancer patients appears to be feasible and safe in selected cancer patients.
