Representative imaging and genomic rearrangements of molecularly characterized patients IX (LCNEC G3) and XII (NET G2). (A) CT and (D) DOTATOC-PET/CT of presacral primary (white arrowheads) and metastases (white arrows). (B) CT-guided biopsy of retroperitoneal lymph node metastasis and (E) ultrasound-guided biopsy of liver metastasis for fresh tissue for genomic analysis. (C, F) Circle plots of genomic rearrangements. Despite slightly lower tumor mutational burden, case XII shows a much higher number of rearrangements as a sign of homologous DNA repair deficiency possibly due to a pathogenic frameshift SETD2 mutation.
