“Fantastic review! A pleasure to read: Understanding the Cancer-Immunity Cycle by Dan Chen, Tom Powles, Ira Mellman and Shannon Turley.

Framework for Anti-Cancer Immune Responses:

  • Describes events initiating anti-cancer immune responses.  
  • Emphasizes iterative nature: T cell killing, antigen presentation and T cell stimulation.
  • Any cycle step can limit immune system, enabling tumor growth.

Recent Advances:    

  • Updated cycle based on past decade progress.    
  • Checkpoint inhibition and dendritic cells’ role evolved.    
  • Tumor microenvironment’s impact considered, discussing tumor immunological phenotype (”immunotype”).

 Clinical Application:    

  • Immune checkpoint inhibition (ICI) success, especially PD-L1/PD-1 therapy.  
  • ICI in perioperative setting, reducing relapse rates, transforming outcomes in specific cancers.
  • Challenges: optimal ICI therapy duration, immune memory, and rechallenging with PD-(L)1 therapy.

 Combination Therapies:    

  • Established PD-1 and CLTA4 inhibition.    
  • Second-generation therapies, like LAG-3, and interest in TIGIT.    
  • Personalized cancer vaccines, CAR-T cell therapy, and T cell engagers explored for effectiveness.  
  • Targeting tumor microenvironment with non-immune therapy explored.  

 Biomarkers and Challenges:    

  • Complex mechanisms of sensitivity and resistance.    
  • Need for unified biomarkers beyond PD-L1 or TMB.    
  • Challenges: suboptimal trial conditions, patient heterogeneity, and identifying appropriate steps for effective anti-cancer response.

 Future Outlook:    

  • Focus on tumor immunotypes, shared immune escape mechanisms, and early disease settings.
  • Continued efforts needed for revolutionizing cancer-immunity cycle.
