Systematic large-scale genetic testing, simultaneously on germline and somatic tissues, is likely to improve decisional algorithms in patients with triple negative breast cancers.
Feasibility of such approach in the clinical setting, in terms of a turnaround time compatible with clinical needs and sensitivity comparable if not superior to single-gene testing needs to be demonstrated before such diagnostc platforms can be routinely implemented in the diagnostic workflow.
Two platforms will be used during the course of the study. The Illumina TruSight Cancer Risk panel is a commercially validated targeted enrichment panel which targets 94 genes and 284 SNPs (Single Nucleotide Polymorphism) associated with a predisposition towards cancer.
The GermSom panel was developed at European Institute of Oncology (IEO) in collaboration with institutions within the Alleanza Contro il Cancro consortium and manufactured by Agilent Technologies. It includes 349 genes with an established function in the biology and/or pharmacological actionability of multiple solid tumors, including breast cancer. It includes all the genomic regions analysed in the Illumina Trusight panel, plus 32 additional regions associated with risk of multiple tumors.
Patients will receive detailed genetic characterization of their germline and their tumor. This will provide the best possible characterization of their risk of developing of a secondary malignancy and can be exploited to identify families at risk for hereditary cancer risk. Patients will also benefit from an increased likelihood of being treated with appropriate drugs and of receiving appropriate surgery.
