Molecular imaging biomarkers for cell-based immunotherapies

Area of Science:

• Oncology
• Immunology
• Medical Imaging

Background:

• Cancer immunotherapy has advanced significantly, offering new treatment options alongside surgery, radiation, and chemotherapy.
• However, not all patients respond to these therapies, and some experience toxicities.
• A key challenge is evaluating the trafficking of activated T-cells into tumors, which conventional imaging cannot adequately assess.

Purpose of the Study:

• To address the need for noninvasive biomarkers for predicting long-term immunotherapy response.
• To explore emerging molecular magnetic resonance imaging (MRI) biomarkers.

Main Methods:

• Focus on molecular MRI biomarkers.
• Exploiting the metabolism and metabolic products of activated T-cells.

Main Results:

• Emerging molecular MRI biomarkers show potential for evaluating T-cell trafficking.
• These biomarkers could enable better patient screening for immunotherapy.

Conclusions:

• Molecular MRI biomarkers offer a promising noninvasive approach to assess immunotherapy effectiveness.
• This could lead to improved patient stratification and treatment monitoring for cancer.
