The IASLC Molecular Database Project: Objectives, challenges and opportunities
(Press-News.org) (Denver, Colo., -- March 31, 2021)- A new Molecular Database Project initiated by the International Association for the Study of Lung (IASLC) will accelerate the understanding of lung cancer biology, clinical care and care delivery on a global scale and will improve the prognosis and optimal treatment of lung cancer across time and space, according to an editorial in the Journal of Thoracic Oncology, an official journal of the IASLC. The editorial can be viewed here: https://www.jto.org/article/S1556-0864(21)01781-0/fulltext.
In the editorial, the IASLC Staging and Prognostic Factors Committee's Molecular Sub-Committee, and committee members, emphasized that there is great opportunity, with the emergence of molecular biomarkers of disease behavior, to improve treatment and survival.
"Biomarker testing, the portal to personalized treatment of lung cancer, has splintered a once seemingly monolithic disease into fragments of genomic and proteomic disease subsets with widely different, but generally improving, treatment and survival expectations," the committee wrote in the editorial.
Staging serves three main purposes: communication, prognostication and direction of treatment. The Tumor (T), Node (N), and Metastasis (M) system is a strictly anatomy-based communication of the extent of cancer and, by inference, its likely effects on quality of life and death (prognosis), which then informs the choice of treatment modalities. Since its introduction between 1966 and 1968, the TNM staging system has facilitated communication about lung cancer across time and space, bridging geographic, linguistic, healthcare infrastructural, socioeconomic and cultural differences. The system has gone through seven revisions, each designed to improve its utility in identifying anatomic clusters of patients with similar prognoses, and, indirectly, improve its practical utility in guiding treatment.
As of December 2020, nine genomic/protein markers could be used to select US Food and Drug Administration (FDA)-approved treatment for stage IV lung cancer (EGFR, ALK, BRAFV600E, ROS1, NTRK, MET exon 14 skipping, and RET mutations; PD-L1 Tumor Proportion Score of > 50%; and microsatellite instability high or mismatch repair deficient tumors). Drugs targeting two other biomarkers, mutations of ERBB2 and KRASG12C, received FDA breakthrough therapy designation for fast-tracked clinical development.
"This trend will only increase with time along with the list of prognostic and predictive markers," the editorial states.
Objectives of the molecular database project include:
Provide a global platform for a deeper, broader understanding of the value of molecular testing,
and targeted therapy for prognostication, prediction and treatment selection across the full
spectrum of TNM stage.
Evaluate novel single or multiple prognostic markers that could add biological information.
regarding the outcome of patients in the different TNM stages. These novel prognostic factors
would add to the current clinical gold-standard criteria and would be formally considered using
criteria developed by the Prognostic Factors Subcommittee, and the Minimal Standards
Create evidence in a set of highly characterized lung cancers with complete clinical, pathologic
and staging information to support the role of biomarkers in lung cancer diagnosis, prognosis
and treatment selection, across the stage spectrum.
Create evidence to support advocacy for routine genomic testing where appropriate.
Define important research questions that might be the focus of observational studies, pragmatic
trials and clinical trials of existing and emerging biomarkers and therapeutics.
Invite applications for projects to analyze the molecular database.

Viruses lurk in the grey area between the living and the nonliving, according to scientists. Like living things, they replicate but they don't do it on their own. The HIV-1 virus, like all viruses, needs to hijack a host cell through infection in order to make copies of itself.
Supercomputer simulations supported by the National Science Foundation-funded Extreme Science and Engineering Discovery Environment (XSEDE) have helped uncover the mechanism for how the HIV-1 virus imports into its core the nucleotides it needs to fuel DNA synthesis, a key step in its replication. It's the first example ...
The qubit is the building block of quantum computing, analogous to the bit in classical computers. To perform error-free calculations, quantum computers of the future are likely to need at least millions of qubits. The latest study, published in the journal PRX Quantum, suggests that these computers could be made with industrial-grade silicon chips using existing manufacturing processes, instead of adopting new manufacturing processes or even newly discovered particles.
For the study, researchers were able to isolate and measure the quantum state of a single electron (the qubit) in a silicon transistor manufactured using a 'CMOS' technology similar to that used to make chips in computer processors.
Furthermore, the spin of the electron was found to remain stable for a period of up ...
Neuroscientists agree that a person's brain is constantly changing, rewiring itself and adapting to environmental stimuli. This is how humans learn new things and create memories. This adaptability and malleability is called plasticity. "Physicians have long suspected that remodeling processes also take place in humans at the contact points between nerve cells, i.e. directly at the synapses. Until now, however, such a coordinated adaptation of structure and function could only be demonstrated in animal experiments," says Prof. Dr. Andreas Vlachos from the Institute of Anatomy and Cell Biology at the University of Freiburg. But now Vlachos, together with Prof. Dr. Jürgen Beck, head of the Department of Neurosurgery at the University Medical Center Freiburg, has provided experimental evidence ...
Astronomers have detected X-rays from Uranus for the first time, using NASA's Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.
Uranus is the seventh planet from the Sun and has two sets of rings around its equator. The planet, which has four times the diameter of Earth, rotates on its side, making it different from all other planets in the solar system. Since Voyager 2 was the only spacecraft to ever fly by Uranus, astronomers currently rely on telescopes much closer to Earth, like Chandra and the Hubble Space Telescope, to learn about this distant and cold planet that is made up almost entirely of hydrogen and helium.
In the new study, researchers used Chandra observations ...
In 1890, psychologist William James described attention as the spotlight we shine not only on the world around us, but also on the contents of our minds. Most cognitive scientists since then have drawn a sharp distinction between what James termed "sensorial attention" and "intellectual attention," now usually called "attention" and "working memory," but James saw them as two varieties of the same mental process.
New research by Princeton neuroscientists suggests that James was on to something, finding that attention to the outside world and attention to our own thoughts are actually two sides of the same neural coin. What's more, they have observed the coin as it flips inside the brain.

Using complementary computing calculations and neutron scattering techniques, researchers from the Department of Energy's Oak Ridge and Lawrence Berkeley national laboratories and the University of California, Berkeley, discovered the existence of an elusive type of spin dynamics in a quantum mechanical system.
The team successfully simulated and measured how magnetic particles called spins can exhibit a type of motion known as Kardar-Parisi-Zhang, or KPZ, in solid materials at various temperatures. Until now, scientists had not found evidence of this particular phenomenon outside of soft matter ...
WASHINGTON (March 31, 2021) -- In 2019, Blacks, Latinos and Native Americans were severely underrepresented in the health care workforce, a trend that shows limited signs of improvement, according to a study published today by George Washington University researchers.
"Our findings suggest that Blacks, Latinos and other people of color have been left behind when it comes to the health professions," Edward Salsberg, senior research scientist and co-director of the Health Workforce Diversity Tracker project at the GW Fitzhugh Mullan Institute for Health Workforce Equity, said. The Fitzhugh Mullan Institute ...
An invasive exotic species is one deliberately or unwittingly introduced by humans into a new habitat, where it becomes an environmental menace. In addition to the loss of biodiversity and other ecological impacts resulting from its presence, an invasive species can lead to economic losses in certain sectors, including agriculture, tourism, and public health. Though biological invasion is the second leading cause of species extinction, decision makers and the general public are still largely unaware of the issue.
After five years of study, the international research team* directed by scientists from the Écologie, Systématique et Évolution (CNRS ...
Comorbidities such as heart disease, respiratory disease, renal disease and cancer lead to an increased risk of death from Covid-19 according to new research from the University of East Anglia (UEA) and the Norfolk and Norwich University Hospital (NNUH).
At the start of the pandemic, there was concern that specific medications for high blood pressure could be linked with worse outcomes for Covid-19 patients.
Previous research from the UEA team showed this wasn't the case and that medications for high blood pressure could, in fact, improve Covid-19 survival rates and reduce the severity of infection.
New findings, published today in the Journal of the American Medical Association (JAMA) Network Open, additionally show that it is comorbidities such as heart disease, respiratory ...
