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.

Abstracts

Clinical Pathology Selected Abstracts

June 2020—More than 1.7 million new diagnoses of cancer occur in the United States each year, and they are almost exclusively made by pathologists who evaluate patient specimens and issue a written diagnostic report. These patients often are not given the opportunity to talk with the pathologist who made the diagnosis or view their tissue through a microscope. There is little published data on patient-pathologist consultation programs in which patients can review their reports and slides with the pathologist. In addition, the number of patients who may be interested in this service is not known. The authors conducted a study to quantify patients’ interest in patient-pathologist consultation programs and qualitatively analyze their motivations for interest or disinterest.

June 2020—The authors conducted a study in which they independently evaluated the utility and prognostic value of tumor budding according to International Tumour Budding Consensus Conference (ITBCC) criteria in a large well-characterized European gastric cancer cohort. They assessed tumor budding according to the ITBCC criteria for 456 consecutive, surgically treated gastric cancers using the scoring system Bd0 (no buds), Bd1 (one to four buds), Bd2 (five to nine buds), and Bd3 (10 or more buds). Cases with tumor budding were divided into low-budding (Bd1/Bd2) and high-budding (Bd3) groups. The tumor budding score was analyzed in relation to clinicopathological parameters, overall survival, and tumor-specific survival. The authors found that 115 (25.2 percent) cases had no tumor budding, 104 (22.8 percent) had low tumor budding, and 237 (52 percent) had high tumor budding.

Molecular Pathology Selected Abstracts

June 2020—The COVID-19 pandemic has focused the world’s attention on using sensitive high-throughput molecular diagnostic testing for the SARS-CoV-2 virus as a public health tool for “flattening the curve” of the infection. Although initial shortages of specialized polymerase chain reaction (PCR) testing reagents that plagued the early weeks of the pandemic have slowly improved (as of CAP TODAY press time), an obstacle to universal testing continues to be the first-step bottleneck of collecting respiratory tract samples for virus-specific reverse transcriptase-PCR (RT-PCR) testing. The traditional gold standard sample for COVID-19 testing has been a nasopharyngeal (NP) swab. However, nationwide shortages of NP swabs, personal protective equipment (PPE), and viral transport media have intermittently delayed the testing process. In an attempt to alleviate these critical sample-collection issues and promote more widespread testing, the medical community and other entities have been investigating alternative sample-collection procedures.

Clinical Pathology Selected Abstracts

May 2020—Laboratory costs represent approximately three to four percent of overall health care expenses but drive 70 to 80 percent of decisions made by physicians. One way to control laboratory testing expenditures is through appropriate utilization. For example, thyroid and antinuclear antibody (ANA) testing have reliable initial screening tests, yet specialized testing is overutilized for both. In 2000 guidelines, the College of American Pathologists and American College of Rheumatology established that the ANA screen by immunofluorescence in the setting of a negative result is sufficiently sensitive not to perform further testing with subserologies and that thyroid-stimulating hormone (TSH) is a sensitive marker of thyroid function and can often be used without further testing with a normal TSH.

May 2020—Flat epithelial atypia is an alteration of terminal duct lobular units by a proliferation of ductal epithelium with low-grade atypia. No consensus exists regarding whether the diagnosis of flat epithelial atypia in core needle biopsy necessitates excision. The authors retrospectively identified all in-house core needle biopsies with flat epithelial atypia obtained at their institution between January 2012 and July 2018. They reviewed all core needle biopsy slides and assessed radiologic-pathologic concordance. An upgrade was defined as invasive carcinoma or ductal carcinoma in situ in the excision, or both. The excision slides of all upgraded cases were re-reviewed.

Molecular Pathology Selected Abstracts

May 2020—Each year a growing number of novel viruses are discovered in the wild animal kingdom with the use of next-generation sequencing technology. However, the current method of functionally assessing the zoonotic potential—that is, the potential to be transmitted to humans—of novel viruses involves synthesis of viral genomes (tens of thousands of bases) and reverse genetic engineering to produce a recombinant virus. This is expensive and time-consuming, and it is not practical due to the scale of new viral strains being discovered. To overcome this hurdle, Letko, et al., developed a rapid and cost-effective method that could functionally assess a number of related viruses for zoonotic potential. The essential component of viral cross-species transmission is cell entry, which is a multi-step process involving attachment of the virus to the host cell surface, receptor engagement, processing of host proteases, and downstream membrane fusion.

Clinical Pathology Selected Abstracts

April 2020—An outbreak of pneumonia occurred in Wuhan, Hubei province, China, in December 2019. A novel coronavirus was identified as the causative agent and named SARS-CoV-2 by the World Health Organization (WHO). The disease, COVID-19, is considered a relative of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). SARS-CoV-2–infected patients presented with a dry cough, dyspnea, fever, and bilateral lung infiltrates.

April 2020—Lymphocytic esophagitis is a well-known manifestation of Crohn disease among children but is not considered an immune-mediated mucositis in adults. The authors conducted a study for which they hypothesized that adult-onset lymphocyte-predominant esophagitis is also an immune-mediated inflammatory pattern, the nature of which has been masked by other conditions that feature esophageal lymphocytosis and occur in older adults. The intent of the study was to consolidate diagnostic criteria for lymphocyte-predominant esophagitis and determine its clinical significance.

Molecular Pathology Selected Abstracts

April 2020—Prior to the recent novel coronavirus outbreak, the vast majority of coronaviruses that were known to be pathogenic in humans caused mild symptoms, with the exception of two strains. These included SARS (severe acute respiratory syndrome coronavirus [SARS-CoV]) and MERS (Middle East respiratory syndrome coronavirus [MERS-CoV]). SARS was documented as having emerged in the Guangdong province in southern China in 2002 and having caused at least 774 reported fatalities worldwide, while MERS, which was first detected in Saudi Arabia in 2012, was responsible for at least 858 fatalities worldwide.

March 2020—U.S. guidelines for human papillomavirus vaccination are 11 to 12 years, with a catch-up vaccination up to age 26 for women and 21 for men. The FDA recently expanded the approved age for HPV vaccination in adult women and men from nine through 45 years. The changes are based on safety data and efficacy as well as potential incremental population-level health benefits. The authors conducted a study to evaluate the added population-level effectiveness and cost-effectiveness of extending the current U.S. HPV vaccination program to women ages 27 through 45 years and men ages 22 through 45 years. They used HPV-ADVISE (agent-based dynamic model for vaccination and screening evaluation), a model for HPV infection and associated diseases specific to U.S. data.
