Pulmonary complications of tyrosine kinase inhibitors and immune checkpoint inhibitors in patients with non-small cell lung cancer

The understanding of cancer biology and the identification of various molecular pathways and targeted oncogenic drivers have led to a paradigm shift in treatment of non-small cell lung cancer. In the last two decades, the therapeutic approach for non-small cell lung cancer (NSCLC) has gradually transitioned from empiric treatment with chemotherapeutic regimens to personalized medicine with precision targets. The major key players in these novel approaches involve targeted therapy, such as tyrosine kinase inhibitors (TKI) and immunotherapy, such as immune checkpoint inhibitors (ICI) blocking intrinsic down regulators of immunity, to achieve anti-cancer effects. These novel agents are generally better tolerated than chemotherapeutics and it is essential to be cognizant of the various drug related adverse effects. Regular follow up of patients with NSCLC by chest computed tomography (CT) surveillance to monitor for disease progression or recurrence is a prerequisite. It is becoming increasingly challenging to identify pulmonary complications related to the use of novel TKI and ICI. Our review focuses on various pulmonary complications of TKI and ICI in patients undergoing treatment for NSCLC, chest CT manifestations, management strategies, and treatment outcomes described in various case reports and case series.
