The landscape of imaging in Myeloma patients has changed rapidly over the past few years. Routine clinical practice and clinical trial settings now utilize more advanced imaging modalities like PET-CT, whole-body MRI, and low-dose CT as compared to whole-body skeletal surveys (Xray) which were more commonly used in the past. These high-resolution imaging modalities lead to higher lesion detection rates at screening and thereby require an ongoing imaging evaluation in a predefined manner to support the efficacy analysis of a therapeutic intervention in clinical trials.
The figures below illustrate imaging presentation in myeloma patients and provide guidance on categorizing these lesions for response evaluation:
Figure a) is a CT head of a patient showing a punched-out lytic lesion in the frontal bone (white arrow). Lytic lesions should be monitored qualitatively as per clinical discretion for progressive disease.
Soft tissue plasmacytoma noted in the pelvis (yellow arrows) in two different subjects: contrast-enhanced CT of pelvis (figure b) and a fused FDG PET image (figure c). Such soft tissue plasmacytoma need to be quantitatively evaluated at a predefined imaging schedule to evaluate the response of therapy along with the other lab parameters.
Regulators are looking for standardized methodologies to be applied upfront in trials to ensure the robustness of the data and its validity. We have noted a trend in the last year wherein health authorities across the globe are asking for a central review of imaging evaluation to mitigate variability in data from site imaging interpretation and across trials.
