Case Report: Case report: Non-invasive mechanical ventilation in combination with bronchoscopy in the treatment of respiratory failure of lung cancer patient. [version 1; peer review: 1 approved, 2 approved with reservations]

Abstract

Background: Respiratory failure (RF) is a common medical problem among cancer patients. Particularly active or ex-smokers diagnosed with chronic obstructive pulmonary disease (COPD) or lung cancer may develop severe hypoxemic and hypercapnic respiratory failure. Moreover, pneumonitis as a complication of the currently widely used immunotherapy of various cancers, may cause respiratory disorders requiring ventilation support. Non-invasive ventilation (NIV) is recommended as the first-line treatment for this type of respiratory failure and reduces the need for endotracheal intubation. Case presentation: We present a case report of lung cancer patient, who received NIV in the treatment of RF due to an infectious exacerbation of COPD. In addition, NIV enabled assisted flexible bronchoscopy (NIV-FB) to be performed. During the procedure tumor samples were collected for further molecular diagnosis of lung cancer. Improvement of the patient general condition and quality of life was also achieved. Conclusions: NIV can be used at any stage of oncological management in patients with lung cancer. It can also be implemented during endoscopic procedures of the respiratory system, as well as support in palliative care of patients with lung cancer at the end of life. Further studies should evaluate the use of NIV in conjunction with various oncological treatments and identify the exact contradictions for BF with NIV support in advanced cancer patients with RF.
