Plodding toward a pancreatic cancer screening test

Pancreatic cancer is one of the most deadly types of malignancies, with a 5-year survival rate after late diagnosis of only about 5%. The majority of patients—about 80%—receive their diagnosis too late for surgery. The disease spreads quickly and resists chemotherapy. In short, there is an urgent need for diagnostic tools to identify this cancer in its earliest stages.

Tumor induction from a distance

Current view is that cancer development is initiated from cells that acquire initial DNA mutations. These in turn provoke additional defects, and ultimately the affected cells begin to proliferate in an uncontrolled manner to develop primary tumors. These can later spread and create metastases, or secondary tumors, in other parts of the body. However, according to a study by researchers at the…

Study provides better understanding of how brain tumors ‘feed’

All cancer tumors have one thing in common – they must feed themselves to grow and spread, a difficult feat since they are usually in a tumor microenvironment with limited nutrients and oxygen. A study at The University of Texas MD Anderson Cancer Center has revealed new details about how an enzyme called acetyl-CoA synthetase 2 (ACSS2) allows brain tumors to grow despite their harsh…

Link between blood sugar and brain cancer found

New research further illuminates the surprising relationship between blood sugar and brain tumors and could begin to shed light on how certain cancers develop. While many cancers are more common among those with diabetes, cancerous brain tumors called gliomas are less common among those with elevated blood sugar and diabetes, a study from The Ohio State University has found. The discovery builds…

Loophole for cancer cells

Many cancers only become a mortal danger if they form metastases elsewhere in the body. Such secondary tumours are formed when individual cells break away from the main tumour and travel through the bloodstream to distant areas of the body. To do so, they have to pass through the walls of small blood vessels. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and…

How tumors adapt to become more aggressive

One of the many reasons tumors are so difficult to treat is that they are able to adapt whenever they are exposed to unfavorable conditions. Hypoxia, or a lack of oxygen, is one example of a phenomenon that should weaken the tumor, but instead, the malignant cells are able to compensate and drive more aggressive disease behavior.

Breast tumors evolve in response to hormone therapy

Many breast tumors grow in response to female hormones, especially estrogen. Drugs that reduce estrogen levels in the body often are effective in reducing tumor size and preventing recurrence of the cancer. But some tumors become resistant to these therapies and continue to grow and spread.

New Biomarker for cancer immunotherapy?

The Ligand PD-L1 is one of the most important targets for cancer immunotherapy with checkpoint inhibitors. But not all tumors have sufficient quantities of PD-L1 ligands on their surface. Scientists from the German Cancer Consortium (DKTK) have now shown that different types of cancer possess different quantities of PD-L1-Gen copies. Genetic analysis of the PD-L1 gene may in the future help to…

3D printed kidney helps save woman's organ

Doctors and scientists at Intermountain Medical Center in Salt Lake City printed and used a 3D kidney to help save a patient's organ during a complicated tumor-removal procedural. The 3D-printed model allowed doctors to study the patient's kidney in 3D to determine how to best remove the tumor as it was located in a precarious location adjacent to vital arteries and veins. Thanks to the model of…
