Oncologic thoracic emergencies of patients with lung cancer.

Patients with lung cancer are the type of cancer patient who are most often admitted to emergency departments due to disease-related complications. An oncologic emergency is defined as any acute event in a patient with cancer that develops directly or indirectly from the tumour and that threatens the patient's life. Oncologic emergencies are divided into metabolic, haematologic and structural emergencies. In this article, we address the main structural thoracic complications of patients with lung cancer, in which imaging tests play an essential role in their diagnosis. The main oncologic thoracic emergencies of lung cancer are airway obstruction, superior vena cava syndrome, acute pulmonary thromboembolism, pericardial tamponade, massive haemoptysis, spinal cord compression and pleural effusion. Oncologic emergencies are a significant cause of morbidity and mortality in patients with lung cancer. Emergency department physicians play a fundamental role in the early detection of these emergencies. The knowledge and correct identification of the main oncologic thoracic emergencies of patients with lung cancer therefore enable optimal diagnostic and therapeutic management.
