Objectives: Multiple myeloma (MM) often develops as a secondary primary malignancy (SPM). The retinoblastoma susceptibility gene (RB1) was the first tumour suppressor gene to be identified. We pooled and analyzed available data to compare the incidence of RB1 gene deletions and other cytogenetic abnormalities in patients with MM alone or as an SPM.Methods: We conducted a retrospective study of 475 patients. The experimental group comprised 18 patients with MM as an SPM, and the control group comprised 457 MM patients. We analyzed the baseline information in both groups, and used the odds ratio (OR), 95% confidence interval (CI), and forest plot to determine the incidence of SPMs with and without cytogenetic abnormalities.Results: The incidence of RB1 gene deletion was higher in the experimental group. There was no significant difference in other cytogenetic abnormalities.Conclusions: RB1 gene deletions appear to be associated with MM that develops as an SPM.

Through the delivery of large international projects including ICGC and TCGA, knowledge of cancer genomics is reaching saturation point. Enabling this to improve patient outcomes now requires embedding comprehensive genomic profiling into routine oncology practice. Towards this goal, this study defined the biologically and clinically relevant genomic features of adult cancer through detailed curation and analysis of large genomic datasets, accumulated literature and biomarker-driven therapeutics in clinic and development. The characteristics and prevalence of these features were then interrogated in 2348 whole genome sequences, covering 21 solid tumour types, generated by the PCAWG project. This analysis highlights the predominant contribution of copy number alterations and identifies a critical role for disruptive structural variants in the inactivation of clinically important tumour suppressor genes, including PTEN and RB1, which are not currently captured by diagnostic assays. This study defines a set of essential genomic features for the characterisation of common adult cancers.
