The potential impact of mouse model selection in preclinical evaluation of cancer immunotherapy

Area of Science:

• Immunotherapy
• Cancer Research
• Preclinical Models

Background:

• CpG oligonucleotides and anti-CD137 immunotherapy are investigated for cancer treatment.
• Orthotopic mouse models offer a more accurate representation of human cancer progression than subcutaneous models.

Purpose of the Study:

• To provide a commentary on the article "Routes of delivery for CpG and anti-CD137 for the treatment of orthotopic kidney tumors in mice".
• To discuss the limitations of subcutaneous tumor models in cancer research.
• To emphasize the advantages of orthotopic models for studying human diseases.

Main Methods:

• Perspective-based commentary.
• Comparative analysis of tumor models (subcutaneous vs. orthotopic).

Main Results:

• The commentary offers insights into the delivery routes of CpG and anti-CD137 for kidney tumors.
• Subcutaneous tumor models may not fully recapitulate the complexity of human cancers.
• Orthotopic models provide a more relevant preclinical platform.

Conclusions:

• The choice of preclinical cancer model is critical for translational success.
• Orthotopic models are superior to subcutaneous models for studying kidney cancer immunotherapy.
• Further research should prioritize orthotopic models for drug development.
