As indicated in Figure 6, in a PD-L1-positive (TPS = 30%) patient with refractory vascular lymphoma, [89Zr]Zr-DFO-KN035 immunoPET (scanning time-points of 53 and 119 h pretreatment) exhibited good imaging performance in detecting multiple LN tumor foci and high splenic uptake. Here, CD274 is linked to neoplasm.
