2016 United States and Canadian Academy of Pathology (USCAP) Annual Meeting

Physicians, scientists, genetic counselors, and allied health staff from Mayo Clinic and Mayo Medical Laboratories are currently attending the United States and Canadian Academy of Pathology (USCAP) 2016 Annual Meeting in Seattle.

In addition to attending, our staff will also be represented by numerous presentations and abstracts, Mayo Clinic Consultants will be available at our booth (#624) Monday, March 14th, from 4-5 pm to answer questions.

Mayo Medical Laboratories representatives will also be available during all exhibit hall hours to discuss:

  • NGS TESTING: Clinically actionable panels to identify mutations across
    numerous genes
  • ONCOLOGY TESTING: Clinically Actionable Testing and Consultation to Guide Patient Care and Manage Treatment Costs
  • HEMATOLOGY TESTING: Advancing the Diagnosis of Hematologic Disorders
  • MAYO CLINIC WORKING GROUPS: Integrated, Multidisciplinary Teams of Pathologists, Clinical Laboratorians, and Physician Specialists to Guide Patient Care
  • MAYO CLINIC PRESENTATIONS: Special Courses, Short Courses, Poster Presentations, and Proffered Paper Presentations


Next generation sequencing has emerged as an accurate, cost-effective method to identify mutations across numerous genes known to be associated with response or resistance to specific targeted therapies.



Mayo Clinic is the most robust laboratory and pathology practice for cancer care in the world. We offer testing that spans diagnostic, theranostic, and prognostic approaches with accompanying specialists for every type and stage of cancer.



As hematology and hematopathology has become an increasingly complex subspecialty, particularly with neoplastic disorders of blood and bone marrow, providing diagnostic, prognostic, and treatment information now requires going beyond the standard test offerings of other laboratories. Our comprehensive test menu has been created to diagnose and treat the full spectrum of hematologic disorders.



A large number of our cases are reviewed by more than one subspecialist pathologist to ensure the best interpretation. This close relationship among Mayo Clinic’s pathologists, clinical laboratorians, and oncologists creates clinical and research collaboration and generates the unique ability to successfully integrate stateof-the-art scientific achievements into clinical practice for patients.

This collaboration also ensures that the right tests are developed, validated, and implemented for the clinical practice and that these tests are ordered at the right time and in the right clinical scenario to help guide patient care.

When a difficult case poses several differential diagnoses, access to the expertise of Mayo Clinic’s consultant working groups creates, in essence, an ad hoc consensus conference or tumor board to form the best opinion.
