Description
UW-OncoPlex™ is a multiplexed mutation assay for tumor tissue that assesses mutations >400 genes related to cancer treatment, prognosis, or diagnosis (listed below).
Please note that UW-OncoPlex™ is intended for solid tumors. For testing related to myeloid and lymphoid disorders, please order Heme Gene Panel by NGS [HCAPA]. For testing related to acute myeloid leukemias and myelodysplastic syndromes, please order Myeloid Gene Panel by NGS [HCAPMY].
The test uses next-generation "deep" sequencing to detect most classes of mutations, including single nucleotide variants, small insertions and deletions (indels), gene amplifications, and selected gene fusions.
Microsatellite instability (MSI) status and tumor mutation burden (TMB) is reported for relevant cancer cases.
This test is designed to detect somatic mutations in cancer and is not designed to detect germline (inherited) variants.
To request testing for one individual gene in the panel, see information for UW OncoPlex Single Gene [OPG].

Microsatellite Instability Analysis
Microsatellite instability (MSI) status is reported for all relevant cancer cases. MSI is detected using methods described in Salipate et al. 2014.
Tumor Mutation Burden Analysis
Tumor mutation burden (TMB) is estimated based on the number of somatic coding mutations per Mb sequenced.

Guidelines
Ordering & Collection
Specimen Type
Collection
Requirements for Specimen Selection
- To ensure clinically relevant results, the most recent and/or metastatic sample is preferred to older specimens, provided sufficient tumor is present (see point 2).
- To ensure detection of all types of mutations there should be at least 10% tumor cells in the tissue area processed for DNA for mutation detection and 20% tumor cells for microsatellite instability evaluation. If there is more than one tissue block, please provide the block that has the greatest percentage of neoplastic nuclei.
- Tissue samples and pathology reports will be reviewed by directors upon receipt for acceptability prior to testing. Director consultation for tissue selection is available if needed (contact Genetics lab).
Specimen Types
Tissue samples
Send one of the following:
- Slides: 1 slide at 4-micron thickness stained with hematoxylin-and-eosin (H&E) AND 10 unstained, non-baked slides at 10-micron thickness (a minimum of 5 unstained slides is acceptable). Unstained slides can be on charged or uncharged slides.
- Tissue Blocks: Provide complete formalin-fixed tissue block containing tumor tissue. Tissue block will be returned at completion of testing.
- Fresh/frozen tissue: 5 microgram tissue in cell culture medium or frozen tissue stored at -20C. Tumor percentage will not be determined prior to sequencing studies.
NOTE: In order to ensure that enough DNA is obtained, the minimum acceptable tissue area is 10 square millimeters when ten 10-micron slides are supplied (1 cubic millimeter of tissue).
