Host immune classifier HIC assays may predict treatment response

Research presented at IASLC 2020 World Conference on Lung Cancer Singapore

2021-01-30
(Press-News.org) (Singapore--4:45 p.m. SPT/3:45 a.m. EST January 30, 2021--Using a host immune classifier (HIC) test for patients with non-small cell lung cancer (NSCLC) may provide better predictors of treatment response and improve outcomes, according to research presented today at the International Association for the Study of Lung Cancer's 2020 World Conference on Lung Cancer Singapore.

Immune checkpoint inhibitors have revolutionized cancer care in patients with advanced stage aNSCLC, but better predictors of treatment response are still needed to guide treatment decisions for patients diagnosed with NSCLC, according to Dr. Wallace Akerley, of Huntsman Cancer Institute in Salt Lake City, Utah. HIC (Host Immune Classifier) is a serum proteomic measure of inflammation. Hot implies that the tumor is inflamed.

Researchers from 33 sites enrolled 3,500 patients with NSCLC in a prospective, observational study that assessed the ability of clinical factors and a clinically validated, blood-based, HIC to predict immune checkpoint inhibitor (ICI) therapy outcomes.

Results in a real-world clinical setting, overall survival (OS) of subjects with newly diagnosed aNSCLC did not differ significantly between ICI and ICI+ chemotherapy (median OS (mOS): 9.4 vs. 12.5 months; hazard ratio, 0.80 [95% CI: 0.54-1.19], p = 0.28).

Results demonstrated that subjects receiving ICI indicated that HIC (HIC defined in title, better performance status (PS) and younger age, but not high PD-L1 expression (either 50% or 90% cutoff) were significantly associated with longer OS. When adjusted for covariates in a multi-variate analysis, HIC and age remained significant predictors of OS (p = 0.0006 and p = 0.005), while PS did not (p = 0.40).

"The HIC test provides clinically meaningful information in addition to currently used clinical factors to potentially help guide immunotherapy treatment decisions for patients with newly diagnosed NSCLC," said Dr. Block.

Study finds potential therapeutic targets to inhibit colorectal cancer progression

Study finds potential therapeutic targets to inhibit colorectal cancer progression
2021-01-30
Nagoya University researchers and colleagues have revealed that colorectal cancer tissues contain at least two types of fibroblasts (a type of cells found in connective tissue), namely, cancer-promoting fibroblasts and cancer-restraining fibroblasts, and that the balance between them is largely involved in the progression of colorectal cancer. Their findings, recently published in the journal Gastroenterology, suggest that artificially altering the balance between the two types of cells could curb the spread of colorectal cancer tumors, which may become an effective strategy for preventing cancer progression. Cancer tissues comprise both cancer cells and non-malignant cells such as fibroblasts. Previous studies have suggested that the proliferation of fibroblasts ...

Radiation Oncology trials using PET with FDG uptake among NSCLC patients

2021-01-30
(Singapore--January 29, 2021 9:35 a.m. SPT/January 28, 2021 8:35 p.m. EST)--Two radiation oncology trials presented at the IALSC World Conference on Lung Cancer Singapore highlight how some researchers are exploring use of higher radiation boost doses to only PET-positive regions in locally-advanced non-small cell lung cancer (NSCLC). A previous large RTOG phase III trial revealed that the unform delivery of a high dose to the entire tumor led to poorer survival. In one study, Prof. Feng-Ming (Spring) Kong, Case Western Reserve University School of Medicine, in Cleveland, Ohio presented the results of a multicenter trial which aimed to ...

Adding ipilimumab to pembrolizumab does not improve efficacy in patients with NSCLC

By changing their shape, some bacteria can grow more resilient to antibiotics

By changing their shape, some bacteria can grow more resilient to antibiotics
2021-01-29
New research led by Carnegie Mellon University Assistant Professor of Physics Shiladitya Banerjee demonstrates how certain types of bacteria can adapt to long-term exposure to antibiotics by changing their shape. The work was published this month in the journal Nature Physics. Adaptation is a fundamental biological process driving organisms to change their traits and behavior to better fit their environment, whether it be the famed diversity of finches observed by pioneering biologist Charles Darwin or the many varieties of bacteria that humans coexist with. While antibiotics have long helped people prevent and cure bacterial infections, many species of bacteria have increasingly been able to adapt to ...

COVID-19 pandemic led to decreased school meal access for children in need across Maryland

COVID-19 pandemic led to decreased school meal access for children in need across Maryland
2021-01-29
School closures during COVID-19 have decreased access to school meals, which is likely to increase the risk for food insecurity among children in Maryland, according to a new report issued by researchers at the University of Maryland School of Medicine (UMSOM). The number of meals served to school-age children during the first three months of the pandemic dropped by 58 percent, compared to the number of free or reduced-price meals served the previous spring. As a result, thousands of children across the state were placed at increased risk of food insecurity, with many likely experiencing the health ramifications ...

Women who develop high blood pressure after birth at greater risk of chronic hypertension

2021-01-29
Washington, DC — Blood pressure that remains elevated over of time — known as chronic hypertension — has been linked to heart disease, which is the leading cause of death in the United States. Recent research has shown that persistent high blood pressure may also increase the risk for stroke and overall mortality. Yet, only about 1 in 4 adults with chronic hypertension have their condition under control, according to the Centers for Disease Control and Prevention. In a new study to be presented today at the Society for Maternal-Fetal Medicine's (SMFM) annual meeting, The Pregnancy Meeting™, researchers from the University of Pittsburgh will unveil findings that suggest that women who develop high blood pressure during pregnancy and who continue ...

A third of Americans say they are unlikely or hesitant to get COVID-19 vaccine

2021-01-29
News reports indicate COVID-19 vaccines are not getting out soon enough nor in adequate supplies to most regions, but there may be a larger underlying problem than shortages. A University of California, Davis, study found that more than a third of people nationwide are either unlikely or at least hesitant to get a COVID-19 vaccine when it becomes available to them. The results are from public polling of more than 800 English-speaking adults nationwide in a study published online earlier this month in the journal Vaccine. "Our research indicates that vaccine uptake will be suboptimal ... with 14.8 percent of respondents being unlikely to get vaccinated ...

Turning on the switch for plasticity in the human brain

Turning on the switch for plasticity in the human brain
2021-01-29
WOODS HOLE, Mass. -- The most powerful substance in the human brain for neuronal communication is glutamate. It is by far the most abundant, and it's implicated in all kinds of operations. Among the most amazing is the slow restructuring of neural networks due to learning and memory acquisition, a process called synaptic plasticity. Glutamate is also of deep clinical interest: After stroke or brain injury and in neurodegenerative disease, glutamate can accumulate to toxic levels outside of neurons and damage or kill them. Shigeki Watanabe of Johns Hopkins University School of Medicine, a familiar face at the Marine Biological Laboratory (MBL) as a faculty member and researcher, is hot on the ...

Scientists solve long-standing mystery by a whisker

Scientists solve long-standing mystery by a whisker
2021-01-29
RIVERSIDE, Calif. -- When we step on the car brake upon seeing a red traffic light ahead, a sequence of events unfolds in the brain at lightning speed. The image of the traffic light is transferred from our eyes to the visual cortex, which, in turn, communicates to the premotor cortex -- a section of the brain involved in preparing and executing limb movements. A signal is then sent to our foot to step on the brake. However, brain region that helps the body go from "seeing" to "stepping" is still a mystery, frustrating neuroscientists and psychologists. To unpack this "black box," a team of neuroscientists at the University of California, Riverside, has ...
