| Summary: | Pembrolizumab is used as a first-line treatment of non-small cell lung cancer. Pneumonitis and interstitial lung disease are among the most common immune-related adverse events. The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections on patients with cancer treated with chemotherapy or immune checkpoint inhibitors (ICIs) is not fully known. Blocking immune checkpoints may conversely augment dysfunctional T-cell responses in severe patients and, in turn, mediate immunopathology. Here, we present a case of SARS-CoV-2 infection complicated by acute respiratory distress syndrome (ARDS) and a fibrotic-like pattern in a patient treated with pembrolizumab for lung cancer. The patient showed a dramatic clinical and radiological response after steroid therapy. Further research is needed to better understand the long-term implications of pembrolizumab therapy in patients recovering from coronavirus disease 2019 (COVID-19) and to develop evidence-based guidelines for managing these complex cases. Patients undergoing oncologic immunotherapy might benefit from early high-dose steroid treatment in cases of viral infections, such as SARS-CoV-2. |
