- Description
- Plasma cell disorders (PCD) range from benign to highly malignant disease. The ability to detect risk-stratifying aberrations based on cytogenetic and molecular genetic assays plays an increasing role in therapeutic decision making. In this study, 58 patients were chosen for screening by comparative genomic hybridisation microarray (aCGH) to identify the new high-risk prognostic markers of chromothripsis and chromoanasynthesis. All patients had an unequivocal clinical diagnosis of a plasma cell disorder (plasma cell myeloma (PCM)(n = 51) or monoclonal gammopathy of undetermined significance (MGUS)(n = 7)) and an abnormal FISH result. There were a total of 17 complex genomic events identified across 9 patient samples, which were selected for further investigation by high definition single nucleotide polymorphism (HD-SNP) microarray. Each event was analysed and characterised for chromothripsis, chromoanasynthesis or a complex step-wise chromosomal event. We describe an effective method to identify the new high-risk prognostic markers of chromothripsis and chromoanasynthesis in plasma cell disorders.
