The effect and safety of immune checkpoint inhibitor rechallenge in non-small cell lung cancer

In this study, the effect of ICI rechallenge was limited. Careful consideration of the administration of ICI rechallenge is necessary. This report involved a small number of cases, so further large prospective studies are warranted to confirm the efficacy of ICI rechallenge and to investigate predictive markers to identify a patient population in which ICI rechallenge is effective.
