Compared with 18F-FDG, 68Ga-pentixafor PET/CT detected more lesions with significantly higher tracer uptake. This case suggests that, for patients with CLL/SLL, 68Ga-pentixafor PET/CT demonstrates significantly superior performance in evaluating the tumor burden and delineating the disease extent compared with 18F-FDG PET/CT.
Expression of IRTA1 alone, or either IRTA1+ or MNDA+, was less frequent among MZL with plasma cell differentiation than among MZL with classical cell morphology (p=0.063 and 0.071, respectively), albeit not significantly. IRTA1 and MNDA are sensitive and specific markers for the differential diagnosis of MZL, and they may be helpful in distinguishing MZL from histologic mimics.
Ultimately, in vitro cellular assays identified three compounds (LC-U7-44, LC-U7-48, and LC-U7-50) that exhibit potent USP7 inhibitory activity alongside favorable cellular anti-proliferative effects. Overall, the established FP assay in this study closes a methodological gap in the evaluation of USP7 inhibitors, and the detailed SAR analysis provides a foundation for the further development of potent USP7 inhibitors.
Finally, we highlight the need for future studies addressing resistance in evolving clinical contexts, such as combination targeted therapies, bispecific antibodies, and CAR T-cell therapy. Taken together, a deeper understanding of clonal evolution is central to the development of personalized therapeutic strategies and to improving long-term outcomes for patients with CLL.
