Lung cancer is the leading cause of cancer-related deaths worldwide and the prognosis remains poor. The recent introduction of the immune checkpoint inhibitor (ICI), or plus chemotherapy, both resulted in the survival benefit for patients with advanced non-small-cell lung cancer (NSCLC), but it remains unanswered which is superior. The current study aimed to estimate the comparative efficacy and safety of ICI-chemotherapy versus ICI-monotherapy in advanced NSCLC. ⋯ Pembrolizumab plus platinum-based chemotherapy was recommended as the optimal first-line therapy for advanced patients with NSCLC. Additionally, PD-L1 alone is not recommended as an adequate molecular biomarker to identify eligible patients for routine clinical practice in immunotherapy.

Gut microbiome has received significant attention for its influences on a variety of host functions, especially immune modulation. With the next-generation sequencing methodologies, more knowledge is gathered about gut microbiome and its irreplaceable role in keeping the balance between human health and diseases is figured out. Immune checkpoint inhibitors (ICIs) are one of the most innovational cancer immunotherapies across cancer types and significantly expand the therapeutic options of cancer patients. ⋯ And then, we expound the impact of gut microbiome on efficacy and toxicity of cancer immunotherapy. Further, we review approaches to manipulating gut microbiome to regulate response to ICIs. Finally, we discuss the current challenges and propose future directions to improve cancer immunotherapy via gut microbiome manipulation.
