September 2022

Highs, lows of tumor mutation burden testing

September 2022—It may not be the oldest story in the world, but in clinical laboratories it’s an oft-told tale: Tumor meets biomarker; drug meets companion diagnostic; both meet FDA approval; clinicians meet with patients offering new hope—and those in the lab are left trying to figure out how to make it all work. That story is playing out again in the realm of measuring tumor mutational burden. In mid-2020 the FDA approved pembrolizumab as a new treatment option in adult and pediatric patients with TMB-high (≥10 mutations/megabase) solid tumors, as determined by the FDA-approved FoundationOne CDx assay. “That doesn’t sound too controversial, right?” says Alain Borczuk, MD, vice chair of anatomic pathology and director of oncologic pathology, Northwell Health Cancer Institute. “It’s not the only way in, but it’s one of the ways in. If you’re arguing for your patient that this is the biomarker that makes them eligible for the drug, then the next questions will be, What was the number? And what was the test?” And it’s off to the races.

As blood supply tightens, so too does mitigation

September 2022—Picture a performer juggling tenpins while walking a high wire, knowing that a hurricane looms. Add a safety net that could disappear at any time. That’s a sense of what hospital transfusion services experience in maintaining enough blood products to meet patients’ needs.

BNP and NT-proBNP: how they differ, what it means

September 2022—Which biomarker for heart failure should be used—BNP or NT-proBNP—and does it matter? That’s the question Christopher W. Farnsworth, PhD, set out to answer in his “hot topic” talk (one of a trio) at the AACC meeting in July.

New data on rapid rule-out using high-sensitivity cTnT

September 2022—A single high-sensitivity cardiac troponin T measurement below the limit of quantitation of 6 ng/L is a safe and rapid method to identify a substantial number of patients at low risk for acute myocardial injury and infarction, say the authors of a recently published study.

What’s required in ’23 for predictive marker tests

September 2022—Beginning next year, two additional predictive marker tests will require enrollment in proficiency testing (PT), but for any predictive marker using immunohistochemistry or in situ hybridization, only laboratories that perform both staining and interpretation must participate in CAP-accepted PT.

Need a written policy or procedure? Look for icon

September 2022—A new icon in the accreditation checklist edition to be released next month will make it easier to know if a written policy or procedure is needed for compliance with a requirement, and easier to inspect and be inspected.

‘Staff love the change’: moving to MLS and why it matters

September 2022—Never a better time than now to switch from the medical technologist job title to medical laboratory scientist. So says John Waugh of Henry Ford Health System, where the job title was formally changed. “Because our people are scientists,” he explains. Waugh and other Compass Group members met online Aug. 2 with CAP TODAY publisher Bob McGonnagle, where they talked about the job title and testing for monkeypox.

From the President’s Desk

September 2022—Like so many pathologists, I have been keeping a close eye on the VALID Act, which would create a new framework for FDA oversight of laboratory-developed tests (LDTs). As I write this, the VALID Act has been voted out of a Senate committee and now awaits further action by the full Senate. I have heard from some pathologists and laboratorians who are concerned about this legislation and about the CAP position on it since the Senate HELP Committee released a draft on May 17, 2022. If you have not followed this bill and the issues of LDT oversight, allow me to offer some context. Regulatory oversight of LDTs has been in active discussion since 2008 when the FDA intervened with a national reference laboratory that was selling a test that had been developed at a prestigious university to identify high-risk women who might have ovarian cancer. Patient advocacy groups had raised a concern because several women had undergone unnecessary prophylactic bilateral oophorectomy based on this LDT. In response, the FDA expressed concern about the public harm, and the reference laboratory pulled the test from the market.

Clinical pathology selected abstracts

September 2022—Clinical laboratory workforce shortages are an issue, in large part because it is difficult to find qualified testing personnel. Pathology residents present a solution to this problem because MD and DO residents who have current training certificates or medical licenses and who are trainees in pathology or other specialties can qualify to perform high-complexity testing.

Anatomic pathology selected abstracts

September 2022—Hypergastrinemia states, such as achlorhydria from gastric mucosal atrophy or a gastrin-producing tumor, have been associated with the development of enterochromaffin-like cell hyperplasia and gastric neuroendocrine tumors.
