Signal PanCancer Panel

Sema4 Signal PanCancer integrates tumor-normal matched DNA and RNA sequencing to deliver accurate insights regarding somatic and germline (inherited)1 alterations to inform treatment decisions for solid and hematological cancers allowing oncologists to:

  • Determine diagnoses and prognoses for solid and hematological cancers
  • Identify and select available targeted therapies, in accordance with level of evidence
  • Identify suitability of current clinical trials
  • Learn about hereditary contributions to various cancer types (with consent)1

 
The Sema4 Signal PanCancer test generates data from whole exome and whole transcriptome sequencing, but report findings on ~2,200 cancer-related genes. This test can detect >99% of mutations associated with FDA-approved therapies, standard-of-care treatments, and investigational therapies in clinical trial2. For additional information, please download the clinical brochure.

Testing includes Microsatellite instability (MSI) and Tumor Mutation Burden (TMB). Options for PD-L1 Biomarkers and DNA Mis-Match Repair (MMR) analysis are also available.

1 Please note that while some inherited genetic changes may be detected, these tests do not replace comprehensive germline testing. If an inherited condition is suspected in the patient or their family member(s), a different test with the purpose of examining germline genetic changes based on family and/or personal history may be appropriate.

Specimen Requirements

Specimen accepted:

  • For tumor: FFPE, Bone Marrow, Fresh Frozen, and Blood are accepted
  • For normal: Saliva, Buccal swab, and blood (if not involved in cancer)
  • Tumor/normal pair required
  • 10 unstained slides of tumor, 10 microns each and H&E, paired normal (if tissue, similar; if blood then one tube (EDTA tube) of blood, or saliva or buccal swabs

 

Minimal samples accepted:

  • FFPE: 9 unstained slides at 10 microns and 1 standard H&E; or 1 block
  • Fresh Frozen (5-10 mm3,)
  • Bone Marrow: 3-5 ml EDTA
  • Blood: 3-5 ml EDTA
  • Saliva: 2.0 ml
  • Buccal swab: 1 swab
  • Tumor cellularity: >=20%

 

Additional requirements:

  • All specimens must be labeled with two unique identifiers. Slides should also be labeled with a block label identity that corresponds with the surgical pathology report
  • Must include a surgical pathology report where available

Turnaround Time

  • Final results delivered in approximately 14-21 days from the time of specimen receipt by Sema4.
