This session explores the evolving role of RAS in precision oncology, from the biology of RAS mutations to the expanding landscape of targeted therapies. Through expert presentations, real-world case discussions, and interactive audience polling, participants will examine best practices for RAS biomarker testing across solid tumors, including lung, colorectal, and pancreatic cancers. The session will highlight practical considerations for tissue and liquid biopsy, strategies to address testing gaps, and the importance of multidisciplinary collaboration to ensure timely identification of patients who may benefit from RAS-targeted therapies.

December 2022—Infantile-onset epilepsy has a variety of underlying etiologies, including brain injury, metabolic disorders, and genetic factors. Refractory epileptic conditions in infants can result in developmental delays, poor quality of life, and increased mortality rates.

December 2022
Q. What is the appropriate way to measure or identify microcytosis or macrocytosis? Read answer.
Q. A six-year-old female with B-cell acute lymphoblastic leukemia and Rh-negative blood is being treated with myeloablative chemotherapy to achieve durable remission or as a bridge to stem cell transplantation, during which supportive transfusions will include repeated platelet transfusions over many weeks. Clinicians are concerned that the patient could become alloimmunized to the D antigen, which, in turn, could affect her ability to eventually bear children.
Apheresis platelets contain a small but finite amount of RBC contaminants, which are not usually quantitated. An optimal strategy to prevent anti-D alloimmunization is to use Rh-negative platelets, but they are often in short supply and cannot be ordered stat in a timely enough manner to ensure every platelet transfusion episode is Rh-negative. We considered using Rh immune globulin (RhIg). However, we recognize that commercial RhIg is designed to prevent D alloimmunization in the setting of obstetric fetal-maternal bleeding.
Is there an optimal dose for RhIg or suggested timing of administration to prevent anti-D alloimmunization in this setting? Read answer.

December 2022—To safely and effectively extend the process of conducting point-of-care testing to staff from various hospital departments is no easy feat. That’s why four full-time employees at Children’s Hospital Los Angeles oversee POC testing, relying heavily on middleware, analytics, and exception-management tools.

December 2022—The Food and Drug Administration has approved the Ventana FOLR1 (FOLR1-2.1) RxDx Assay, the first immunohistochemistry companion diagnostic test to aid in identifying epithelial ovarian cancer patients who are eligible for targeted treatment with Elahere (mirvetuximab soravtansine-gynx). Elahere is a first-in-class antibody-drug conjugate therapy developed by ImmunoGen and approved under the FDA’s accelerated approval program for the treatment of FRα-positive platinum-resistant ovarian cancer.
From the President’s Desk
November 2022—Like me, many of you can remember when you first thought about specializing in pathology, a decision that for a lot of us was made difficult by the notion of “disappearing” from the scene—working behind the scenes and in relative obscurity. As a specialty we are not as self-explanatory as surgery or pediatrics; indeed it can be exhausting for all concerned to explain, even to our fellow physicians, what we do. And so we often find ourselves somewhere between disregarded and misunderstood. Despite this, there is no other specialty with comparable impact. We are aware each time we sign a pathology report that a cascade of usually predictable consequences will ensue, and that upon this work the types of treatment, expectations for response, and tenor of conversations will depend. We know each time we validate a new test, review quality metrics, or accept a specimen for testing that subsequent laboratory results will be accepted as credible and acted upon. In short, while pathologists are not always visible, there can be no doubt that pathologists are palpable.

November 2022—Exposure to lead may cause severe illness in children, including neurological damage, organ failure, and even death. The Centers for Disease Control and Prevention and other agencies recommend routine testing for blood lead levels (BLL) as part of a well-child examination to identify elevated levels and, subsequently, eliminate exposure to lead and initiate therapeutic interventions.

November 2022—Appendiceal mucinous neoplasms show a range of morphologic features and biological risk. At one end of the spectrum, high-grade adenocarcinomas are cytologically malignant and exhibit infiltrative invasion, lymph node metastases, and behavior similar to that of extra-appendiceal mucinous adenocarcinomas.

November 2022—Spontaneous coronary artery dissection is an uncommon cause of acute heart attack. It is not associated with high cholesterol or atherosclerosis but, instead, occurs when a small tear or separation in the wall of the coronary artery leads to blood entering a false lumen, occluding blood flow and impairing oxygenation of the heart muscle.

November 2022—Lab test result formats are not standardized, potentially causing confusion when the same test results are displayed differently—for example, when a positive pregnancy test appears as +, P, or positive, or an indeterminate test result appears as DNR, which could be interpreted to mean did not report, did not react, or even do not resuscitate. Because of this issue, the authors trialed standard laboratory result formats across the 130 facilities that are part of the Veterans Health Administration, each of which has one or more CLIA-certified laboratories. The authors selected the most common laboratory tests from each facility, which composed at least 95 percent of a facility’s monthly laboratory test volume between 2000 and 2015. They then specified the standard result formats for these tests based on the facilities’ feedback. Personalized emails were sent weekly, over a 15-week period in 2016, to the facilities’ lab information systems managers, lab managers, and laboratory directors.
