This study is a retrospective analysis of consecutive patients with venous thromboembolism (VTE) treated by the Pulmonary Embolism Response Team CELZAT (PERT-CELZAT) that compares the clinical characteristics, outcomes, and mortality of patients with and without cancer. It shows that patients with cancer can be successfully treated for pulmonary embolism (PE) with their in-hospital outcomes and mortality rate at the same level as patients without cancer. The study postulates that patients with PE, especially those in the intermediate and high-risk group or with contraindications for standard therapy, should be followed by a multidisciplinary team. This may result in lower complication rates and lower in-hospital mortality. However, the long-term follow-up shows that, despite successful treatment in the acute phase, the cancer patients had shorter survival times, which may be associated with the progression of neoplastic disease.
