The biomarkers related to immune related adverse events caused by immune checkpoint inhibitors.

The enthusiasm for immune checkpoint inhibitors (ICIs), an efficient tumor treatment model different from traditional treatment, is based on their unprecedented antitumor effect, but the occurrence of immune-related adverse events (irAEs) is an obstacle to the prospect of ICI treatment. IrAEs are a discrete toxicity caused by the nonspecific activation of the immune system and can affect almost all tissues and organs. Currently, research on biomarkers mainly focuses on the gastrointestinal tract, endocrine system, skin and lung.

In vitro synergistic antitumor efficacy of sequentially combined chemotherapy/icotinib in non‑small cell lung cancer cell lines.

The concurrent administration of chemotherapy and epidermal growth factor receptor‑tyrosine kinase inhibitors (EGFR‑TKIs) has previously produced a negative interaction and failed to confer a survival benefit to non‑small cell lung cancer (NSCLC) patients compared with first‑line cytotoxic chemotherapy.
