Immune-checkpoint inhibitors (ICIs) have changed the management of advanced cancers. However, patients with pre-existing autoimmune diseases (ADs) have usually been excluded from clinical trials of ICIs due to concerns about exacerbation of AD. Here, we combined ICIs with selective immunosuppressant treatment in a metastatic lung adenocarcinoma patient with active pre-existing polymyalgia rheumatica (PMR). Remarkably, the strategy led to durable response and no exacerbation of PMR. Thus, we provide the first clinical evidence of treating metastatic cancer with ICIs and concomitant use of tocilizumab and hydroxychloroquine for active pre-existing PMR.
