This table represents a short version of the response criteria with focus on CT and FDG PET/CT findings. 214, No. (b) Axial contrast-enhanced CT image shows tumor extension along the spermatic cord (arrow; the testis is not depicted on this image). 3. The proposed five-point scale is a visual measure of FDG PET/CT response assessment; the risk of a degree of subjectivity in the interpretation of FDG avidity has not been eliminated. In the immunocompromised patient, lesions are more often heterogeneous with peripheral enhancement, mimicking glioblastoma multiforme. To better characterize the dynamics of this redistribution phenomenon, we correlated serial lymphocyte counts with volumetric changes in lymph node and spleen sizes during ibrutinib therapy. The overall trend is toward a more simplified response assessment.

Four categories for CT have been outlined: (a) complete radiologic response, all nodes less than or equal to 1.5 cm in longest diameter, disappearance of all CT findings of lymphoma; (b) partial remission, 50% or greater decrease in disease burden; (c) stable disease, less than 50% decrease in disease burden; and (d) progressive disease, new or increased adenopathy or new extranodal lymphoma.
