DNA was extracted from paraffin-embedded tissue blocks with a QIAamp Tissue KitTM (Qiagen, Hilden, Germany). Then, 10 ng DNA per tissue sample was provided for sequencing. The DNA library was created by multiplex polymerase chain reaction with the Ion AmpliSeq Cancer Hotspot Panel v2 (Thermo Fisher Scientific, Waltham, MA, USA), which covers the mutation hotspots of 50 genes. The panel includes driver mutations, oncogenes, and tumor suppressor genes. By mid-2018, the gene panel was expanded using the 161-gene next-generation sequencing panel of Oncomine Comprehensive Assay v3 (Thermo Fisher Scientific, Waltham, MA, USA), which covers genetic alterations and gene fusions. The Ampliseq cancer hotspot panel was sequenced with an Ion PGM (Thermo Fisher Scientific, Waltham, MA, USA) and the Oncomine Comprehensive Assay v3 on an Ion S5 sequencer (Thermo Fisher Scientific, Waltham, MA, USA). The generated sequencing data were analyzed afterward with the help of the Ion Reporter Software (Thermo Scientific Fisher Scientific, Waltham, MA, USA). We referred to the BRCA Exchange, ClinVar, COSMIC, dbSNP, OMIM, and 1000 genomes for variant calling and classification.

DNA was extracted from paraffin-embedded tissue blocks with a QIAamp Tissue KitTM (Qiagen, Hilden, Germany) and 10 ng DNA per tissue sample was provided for sequencing. The DNA library was created by multiplex polymerase chain reaction with the 161-gene next-generation sequencing panel of Oncomine Comprehensive Assay v3 (Thermo Fisher Scientific, Waltham, MA, USA). The panel includes driver mutations, oncogenes, tumor suppressor genes, and gene fusions. See supplementary information for complete list of the gene panel. The Oncomine Comprehensive Assay v3 was optimized for sequencing on an Ion Personal Genome Machine System (Thermo Fisher Scientific). The generated sequencing data were afterwards analyzed with the help of the Ion Reporter Software (Thermo Scientific Fisher). We referred to BRCA Exchange, ClinVar, COSMIC, dbSNP, OMIM and 1000 genomes for variant calling and classification. The variants were classified according to a five-tier system comprised of the modifiers pathogenic, likely pathogenic, uncertain significance, likely benign, or benign. This classification was based on the standards and guidelines for the interpretation of sequence variants of the American College of Medical Genetics and Genomics. The variants pathogenic and likely pathogenic were taken into consideration for the recommendation of targeted therapy.

METex14 skipping mutations were identified through several methods including NGS of tissue using DNA- and RNA-based assays (TruSight Tumor 26 assay, Ilumina, San Diego CA; Oncomine Comprehensive Assay v3, Thermo Fischer, Waltham, MA; or FoundationOne CDx, Foundation Medicine, Cambridge, MA), or plasma-based NGS with commercially available assays (Guardant360 CDx, Redwood City, CA and FoundationOne LiquidCDx, Foundation Medicine, Cambridge, MA). Programmed death-ligand 1 (PD-L1) assessment was performed using the 22C3 pharmDx assay (Agilent Technologies, Dako, Carpinteria, CA) at all centers.

All laboratory work was performed according to the respective manufacturer’s protocol available online. The preparation of formalin-fixed, paraffin-embedded (FFPE) tissue samples was performed identically for all three workflows. The purification of DNA from the FFPE tissue samples was performed using the Maxwell® RSC Instrument (Promega Corporation) with the Maxwell® RSC FFPE Plus DNA Kit (Promega Corporation). Therefore, the tumor containing area of a tissue section or respectively the total area of a normal tissue section was scraped off the slide, placed into a 1.5 ml tube and centrifuged at maximum speed for 15 sec. 20 μl of 20 mg/ml Proteinase K and 180 μl Incubation Buffer was added. Overnight samples were heated at 70°C. After incubation the samples were mixed with 400 μl Lysis Buffer and transferred to the Maxwell® RSC Cartridge. Further preparation and the instrument run were performed according to manufacturer’s protocol. The concentration of DNA was measured with the Qubit 4 Fluorometer (Invitrogen). For the library preparation, panel-specific amounts of DNA were used as input: 40 ng for the GeneRead™ QIAact BRCA UMI Panel (QIAGEN), 20 ng for the Oncomine™ Comprehensive Assay v3 (Thermo Fisher) and 20 ng for the AmpliSeq™ BRCA Panel (Illumina®).

Up to five 10-μm-thick sections of formalin-fixed, paraffin-embedded tissue blocks were used for DNA and RNA sequencing analysis. Representative tumor areas were manually micro-dissected. DNA and RNA were extracted using the Invitrogen Recover All Total Nucleic Acid Isolation Kit (Invitrogen, Carlsbad, CA, USA). Massively parallel sequencing of cancer-related gene panels (Oncomine Comprehensive Assay v3, ThermoFisher Scientific Waltham, MA, USA) was performed using the Ion Chef and Ion Torrent sequencing platforms. Sequence data were aligned against the human reference genome (hg19 build).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
