A comprehensive analysis of 8,314 lung cancer patients from the FAERS database revealed that pembrolizumab combined with pemetrexed and platinum chemotherapy significantly increases the risk of renal and hepatobiliary disorders compared to chemotherapy alone.
The combination therapy demonstrated a delayed onset of adverse events, with most occurring within three months versus six weeks for chemotherapy alone, requiring enhanced monitoring protocols during the initial treatment period.
Gender and age disparities emerged as critical factors, with elderly patients (≥65 years) experiencing higher rates of blood disorders and kidney problems, while female patients showed increased susceptibility to nephrotoxicity across both treatment regimens.
Despite increased toxicity risks, the safety profile remains within acceptable ranges, with common adverse events including anemia, neutropenia, and thrombocytopenia being similar between treatment approaches.
