Imaging in Immuno-Oncology

The discovery that immunomodulators that enhance the immune response to cancer has led to the adoption of therapies that target tumor immune components.  These therapies bring about significant increases in survival for a range of malignancies.  However, they are expensive and have considerable side-effects.

There are currently no reliable non-invasive surrogate measures for efficacy.  This represents an unmet need for such measures, to decrease ineffective therapy and patient morbidity.  Moreover, early identification of a lack of efficacy can potentially bring about prompt institution of more effective therapies.

Imaging has been utilized to identify response to therapy, with the assumption that imaging response (or progression-free survival) and overall survival are closely associated.  This webinar will review the current status of imaging in immunomodulatory (IO) therapies; promising future directions in imaging biomarkers for IO, and barriers to adoption of imaging surrogates for IO therapeutic efficacy.

At the end of the webinar, the participant should:

  • Have a clear understanding of current methods for imaging biomarkers in IO
  • Become aware of developments in IO imaging, with a focus on molecular imaging
  • Become familiar with the potential and the pitfalls of imaging in IO
