Precipios: Yale Study Demonstrates Four-Fold Superiority of Academic Level Diagnostic Accuracy
NEW HAVEN, Conn., Jan. 10, 2018 (GLOBE NEWSWIRE) -- Specialty diagnostics company Precipio Diagnostics' (NASDAQ:PRPO), today announced preliminary data from an ongoing study on the impact of academic pathology expertise on diagnostic accuracy.
The purpose of the study was to independently evaluate the effect of academic pathology on the massive problem of misdiagnosis, and determine the impact of Precipio’s business model as a solution to this problem.
Initial data shows that of the biopsy samples that Yale specialist pathologists provided a second opinion on and arrived at different diagnoses, ~73% arrived at a diagnosis that either definitely or possibly changed the patient treatment plans.
Superior Diagnostic Accuracy
This is a substantial number, both strengthening industry data on the problem of misdiagnosis; providing powerful evidence to the consequences to patient care; and validating Precipio’s business model as the only innovative solution of its kind to combat the problem of misdiagnosis.
This data is further strengthened by the comparative data generated internally by Precipio, demonstrating that in the first 100 cases initially diagnosed by academic expert pathologists at Yale and then sent to an outside pathologist for a second opinion, in 99% of those cases, the second opinion confirmed the primary diagnosis arrived at by Yale.
“Preliminary findings of the study are consistent with independently reported data on cancer misdiagnosis rates of about 20%,” said Dr. Christopher Sebastian, a pathology resident at Yale University and co-principal investigator. “Pathology is complex and rapidly evolving. It’s not surprising that subspecialty training and an academic focus help pathologists more accurately diagnose patients.”
“This is further independent evidence of the importance of academic level, specialist pathology in preventing billions of wasted dollars and untold family trauma resulting annually from pervasive cancer misdiagnosis,” commented Ilan Danieli, president & CEO. “It’s a validation of our mission to bring life-saving, academic level diagnostics to the millions of US patients diagnosed with cancer every year along with enormous cost saving benefits to physicians, hospitals, and insurance companies. Our unique business model continues to demonstrate that it can bring both tremendous clinical impact, as well as substantial, quantifiable financial value to the industry stakeholders.
The study’s purpose, launched July 2017, is to evaluate the hypothesis that academic pathologists’ expertise result in a higher rate of diagnostic accuracy than the current industry is providing. The study was designed to retrospectively evaluate the concordance in two sets of data in order to demonstrate this hypothesis.
The first cohort consists of patients who received their primary diagnoses non-academic community hospitals or national reference labs (representative of the industry), and were then referred to an academic pathology institution (Yale University) for a second opinion consultation. The purpose of evaluating this cohort was to re-assess the diagnosis received outside of an academic institution, and then have an academic expert specialist evaluate its accuracy.
The second cohort consists of patients initially diagnosed at Yale University, and then referred to another academic institution for a second opinion consultation, (for example at the Brigham & Women’s Hospital in Boston, or at Memorial Sloan Kettering Cancer Center in New York). The purpose of evaluating this cohort was to review the diagnosis rendered by an academic expert, and assess its accuracy by having it reviewed by a peer academic expert – thus, subject to the same scrutiny as the first cohort. In the cases where there is a disagreement between primary diagnosis and the second opinion evaluation, the patient sample will be submitted to a third party academic institution to act as the arbiter (a process which currently does not exist in the industry). For the purpose of this study, academic expert pathologists at University of Pennsylvania will review each of the discordant cases and determine the correct diagnosis.
Study investigators at Yale anticipated the first cohort would show a significant rate of misdiagnosis with meaningful consequences to the patient; while the second cohort would show minimal discordance, reflecting an overall substantially higher level of diagnostic accuracy rendered by academic pathologists.
To date, a total of 315 cases have been reviewed, 213 of which belong to the first cohort of the study, consisting of patients initially diagnosed at a non-academic facility, and then receiving a second opinion consult at Yale University. The preliminary data reveals that, of the cohort of patients initially diagnosed at a non-academic institution, in 45 patients (21% of the cases) the academic pathologist arrived at a different conclusion during their second opinion assessment.
Furthermore, in 33 of those cases (>73%), the change in diagnosis had a potential substantial impact on patient treatment plan and is considered a material discordance. In the remaining 102 cases reviewed that belong to the second cohort, in only 5% of the patients that were initially diagnosed by an academic expert, the second opinion diagnosis differed from the primary diagnosis. However, in 0% of those cases, did the change impact the patient treatment plan and is therefore not considered a material discordance.
The study will ultimately include at least 1,000 patients to further demonstrate the value of academic expertise in the diagnostic process. It is expected to be completed by the end of Q1-2018, after which the results will be compiled and published in a peer-reviewed industry journal.
“These preliminary results demonstrate the value of academic expertise in pathology diagnosis. They also lend support to the Precipio business model of utilizing academic pathologists to reach superior diagnostic accuracy in the reference lab setting,” said Professor David Hudnall, Yale Professor of Pathology and Precipio medical director. “I look forward to witnessing the impact of Precipio’s model of academic-reference lab collaboration on patient care, and how it will affect the industry”, concluded Dr. Hudnall.
In our mission to eradicate disease misdiagnosis, Precipio harnesses academic expertise and delivers it to community oncologists and hospitals worldwide, helping to provide patients with the most accurate diagnosis. In an industry that is gradually shifting towards value-based services, the importance of arriving at an accurate diagnosis can no longer be overlooked. Our clinical laboratory receives patient specimens and ensures that they are reviewed by the specific expert relevant to the type of disease diagnosed. This has resulted in a substantially higher level of accuracy delivered by Precipio. While the obvious key beneficiary is the patient and their physician who are armed with the correct information to battle cancer; the health insurance companies too can avoid billions of dollars in waste as a result of misdiagnosis.
Precipio is eradicating the problem of misdiagnosis which affects millions each year and costs billions of healthcare dollars in waste. By harnessing the intellect, expertise and proprietary technologies developed within academia, such as Yale School of Medicine and Harvard’s Dana Farber Cancer Institute, delivering quality diagnostic information to physicians and their patients worldwide, Precipio disrupts current diagnostics with a superior level of diagnostic accuracy.
