Clinical status and research progress of immunotherapy resistance in lung cancer
Lung cancer is the malignant tumor with the highest incidence and lethality globally.In recent years,emerging immunotherapy based on the immune checkpoint inhibitors,programmed cell death protein-1 and its ligand(PD-1/L1),as a representative,has made revolu-tionary breakthroughs in the field of lung cancer.The indications for this treatment mode have moved from driver-gene-negative advanced or locally advanced lung cancer to adjuvant and neoadjuvant treatment of perioperative lung cancer,and an increasing number of mono-clonal antibodies against PD-1 and PD-L1 has been approved for the treatment of lung cancer.However,with the widespread use of immun-otherapy,the problem of drug resistance has gradually come to the fore.Only a small proportion of the overall lung cancer population re-sponds to immunotherapy,bringing a new round of challenges to lung cancer treatment.In this paper,the clinical status of immunotherapy resistance in lung caner is reviewed,and cutting-edge advances in knowledge of resistance mechanisms and coping strategies are reviewed,with the aim of providing clinicians with ideas and the basis for formulating individualized,precise treatment plans.
