Title Clonal Analyses of Refractory Testicular Germ Cell Tumors
Organism Homo sapiens
Experiment type Genome variation profiling by array
Summary We used DNA content-based flow cytometry to distinguish and isolate nuclei of clonal tumor populations from primary and metastatic refractory testicular germ cell tumors (TGCTs) tissues. We then interrogated each sorted tumor populationwith whole genome aCGH and next generation sequencing (NGS). we have explored the clonal basis of refractory TGCT by investigating distinct tumor populations that were present in each tumor. Notably this included resected primary tissues and treatment refractory metastases that arose after high dose chemotherapy. These results provide new knowledge regarding the role of clonal selection and selected genomic lesions in the resistance to chemotherapy in TGCT within this exceptional cohort.
 
Overall design We applied a systematic approach combining DNA content flow cytometry, whole genome copy number and whole exome sequence analyses to interrogate tumor heterogeneity in primary and metastatic refractory testicular germ cell tumors (TGCTs). We identified both known and novel somatic copy number aberrations and mutations including candidate markers for platinum resistance that were present in a primary tumor of mixed histology and that remained after tandem autologous stem cell transplant..
