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.

Anatomic pathology selected abstracts

September 2020—Identifying patients who respond to immune checkpoint blockade is a significant challenge in oncology. PD-L1 expression by immunohistochemistry is the diagnostic gold standard for patient selection, but it does not capture all patients who may respond to immune checkpoint blockade (ICB). Recent gene-expression studies of high-grade serous ovarian carcinoma have defined an immunoreactive molecular subtype that shows a measurable favorable difference in patient survival compared with nonimmunoreactive subtypes, but no studies have demonstrated its impact on predicting response to ICB. As a step toward establishing the predictive value of gene-expression classifiers in ICB, the authors assessed the relationship between PD-L1 IHC and molecular subtypes of ovarian epithelial cancer. They analyzed 93 tissue specimens from patients with stages III and IV disease and compared PD-L1 IHC with gene expression by Agilent microarrays using The Cancer Genome Atlas-defined subtypes.

September 2020—Whole genome methylation profiling is used to subclassify neuroepithelial tumors and soft tissue sarcomas. Extending its use to much more common cancers, such as prostate cancer, has the potential to benefit a large number of patients. Metastatic castration-resistant prostate cancer (mCRPC) is the incurable and lethal form of prostate cancer and consists of different subgroups with variable morphologies and genomic alterations. The emergence of distinct subtypes of mCRPC likely represents adaption of the cancer cells to treatment and the microenvironment. The authors conducted a study that integrated methylation profiling with genomic sequencing and RNA transcriptome analysis in 100 mCRPC tumors, yielding a comprehensive molecular profile of these metastatic tumors.

Pathology informatics selected abstracts

September 2020—Whole slide imaging has been available for clinical, research, and educational use for decades, with several digital pathology systems cleared by the FDA for primary diagnosis. However, widespread adoption of this technology for routine practice has been slow. Likely reasons for the slow uptick in employing whole slide imaging (WSI) for sign-out include the cost of these systems, their lack of interoperability with laboratory information systems, pathologist resistance to using this digital modality, and regulatory restrictions on remote sign-out imposed by the Clinical Laboratory Improvement Amendments (CLIA). However, the COVID-19 pandemic led the Trump administration, on March 26, to temporarily waive these CLIA regulations, giving pathologists the flexibility to sign out cases digitally from their homes.

Q&A column

Q. Is the evaluation of gene copies by RT-PCR or multiplex ligation-dependent probe amplification a qualitative or quantitative assay? Copy number analysis of genes or chromosomes determines a numerical value, with a normal autosomal count being two. However, an FDA-approved microarray test (CytoScan Dx assay, Thermo Fisher Scientific) is labeled as a qualitative assay for the detection of copy number variations. Read answer.
Q. How does using sodium heparin, in an attempt to reduce EDTA-induced platelet clumps, affect the platelet count? Read answer.
Q. How do you know whether thyroid-stimulating hormone isoforms have been measured in an assay when the TSH levels are very high and free T4 is considerably less than the reference interval (i.e. less than 50 percent of the reference interval)? Read answer.

It has track-connectable modular configurations with one workflow for multiple sample types, end-to-end automation with predictable lab turnaround time, and IT integration with sample and test tracking.

From the President’s Desk: Virtual meetings, for now

August 2020—In the past six months, many of us have developed video conferencing skills to an extent we never imagined we would need. Until the COVID-19 pandemic led to lockdowns in several states, a great deal of expertise in Zoom and other similar platforms was not a high priority among many pathologists. I am proud that our community adapted quickly and skillfully to continue providing the best care possible to our patients.

Clinical pathology selected abstracts

August 2020—Bacterial contamination of platelets continues to be an important cause of transfusion-associated morbidity and mortality. From 2001 to 2016, there were 51 deaths reported to the FDA due to transfusion of apheresis products contaminated with bacteria, including 30 deaths since testing for bacterial contamination was mandated in 2004. This mandate was implemented through primary culture of single-donor apheresis platelets in 2004 and then prestorage pooled platelets (PSPPs) in 2007. The authors conducted a study to compare the platelet bacterial contamination and septic transfusion rates before and after introducing testing of pooled and apheresis platelets by primary culture over an extended time period. They cultured platelet aliquots at issue and evaluated transfusion reactions.

August 2020—The authors conducted a study in which they reviewed 354 cases of malignant diffuse mesothelioma in women from a database of 2,858 histologically confirmed cases. Pleural predominance was noted with 78 percent of pleural malignant mesotheliomas (MM) and 22 percent of peritoneal MM. The pleural tumors consisted of 72 percent epithelioid, 19 percent biphasic, and nine percent sarcomatoid variant. The peritoneal tumors consisted of 82 percent epithelioid, 13 percent biphasic, and five percent sarcomatoid. The immunohistochemical profile was typical of what is well accepted and previously described for MM.

Molecular pathology selected abstracts

August 2020—Patients and families suspected of having Mendelian diseases, syndromes thought to be caused by a single mutated gene, often undergo comprehensive next-generation sequencing to determine the underlying pathogenic variant. Whole exome sequencing, in which the coding regions of all genes are analyzed, is usually the preferred testing method. However, this identifies the diagnostic pathogenic variant in only 25 to 52 percent of cases. Whole genome sequencing appears to confer only marginal benefit over whole exome sequencing, presumably because the pathogenic variants likely are not missed by whole exome sequencing but may be misinterpreted as nondiagnostic. Among the variants that are difficult to interpret are those that affect RNA by directly influencing transcription, or altering normal splicing, or by mediating their effects through chromatin.
