Cancer repair mechanism could be potential drug target

Searching for ways to extend the survival benefit of targeted therapies, a team led by researchers has identified a potential new tactic to disrupt the repair mechanism that cancer cells use after treatment, blunting their ability to regenerate. The approach could present a new treatment strategy.

Distinct classes of fibroblasts in tumors play opposing roles, promoting or restraining pancreatic cancer growth

Researchers discovered that two distinct classes of fibroblast cells accumulate in pancreatic tumors and play opposing roles to promote and restrain pancreatic cancer growth. Appropriately targeting these cells may offer options to improve treatment outcomes.

Black patients with cancer fare worse with COVID-19, study shows

Lack of access to health care, social determinants of health, preexisting comorbidities and reduced access to clinical research are common to both cancer and COVID-19 in Black individuals. Together these two diseases create a perfect storm in this population, a new study indicates.

Researchers offer new treatment protocol for advanced head and neck cancer

The current treatment of patients diagnosed with advanced or metastatic head and neck cancer (HNC) is ineffective. Researchers have investigated and validated a potential treatment combination against the aggressive disease driven by hyper-activation of a specific signaling pathway, which is found in over 40 percent of HNC patients.

Half of all women experience false positive mammograms after 10 years of annual screening

Half of all women experience a false positive mammogram after 10 years of annual breast cancer screening with 3D mammography, a UC Davis-led study estimates. This risk was lower for women who had mammograms every other year. 3D screening showed slightly lower false positive results than standard mammography.

In animal study, implant churns out CAR-T cells to combat cancer

Researchers have developed an implantable biotechnology that produces and releases CAR-T cells for attacking cancerous tumors. In a proof-of-concept study involving lymphoma in mice, the researchers found that treatment with the implants was faster and more effective than conventional CAR-T cell cancer treatment.

Novel therapeutic strategy shows promise against pancreatic cancer

Pancreatic cancer is notoriously difficult to cure or even treat. Now, a new strategy has succeeded in making pancreatic tumors visible to the immune systems of mice and vulnerable to immune attack, reducing cancer metastases by 87%.

Could diet modification make chemotherapy drugs more effective for patients with pancreatic cancer?

The findings of a new study suggest that a ketogenic diet — which is low in carbohydrates and protein, but high in fat — helps to kill pancreatic cancer cells when combined with a triple-drug therapy. In laboratory experiments, the ketogenic diet decreased glucose (sugar) levels in the tumor, suggesting the diet helped starve the cancer. In addition, this diet elevated ketone bodies produced by the liver, which put additional stress on the cancer cells.

Bone marrow cancer: Potential drug targets

New research finds that patients with ASXL1-mutant chronic myelomonocytic leukemia — an uncommon type of cancer of the bone marrow — have distinctive epigenetic changes that can activate harmful genes and cause the cancer to grow faster. The ASXL1 genetic mutation also can transform the disease into the more aggressive acute myeloid leukemia.
