Concurrent high-grade glioma with cavernous malformations and pathogenic variants in PDCD10 and SMARCA4.

The co-occurrence of multiple disease processes can pose diagnostic challenges. We report an unusual case of a patient found to have co-occurrences of an IDH1-mutant high-grade glioma along with cerebral cavernous malformations and pathogenic germline variants in PDCD10 and SMARCA4. Somatic testing was done on the tumor and identified a SMARCA4 and two TP53 variants.

Analysis of ex vivo expanded and activated clinical-grade human NK cells after cryopreservation.

Background Aims: Several methods to expand and activate (EA) NK cells ex vivo have been developed for the treatment of relapsed or refractory cancers. Infusion of fresh NK cells is generally preferred to the infusion of cryopreserved/thawed (C/T) NK cells because of concern that cryopreservation diminishes NK cell activity. However, there has been little head-to-head comparison of the functionality of fresh versus C/T NK cell products.
