99mTc-interleukin-2 scintigraphy as a potential tool for evaluating tumor-infiltrating lymphocytes in melanoma lesions: a validation study.

Abstract

99mTc-IL2 scintigraphy provides a means of in vivo measurement of the extent of tumor infiltration of IL2R-positive cells, thereby providing valuable prognostic information for selection of patients who may benefit from IL2 immunotherapy.
