Why breast cancer metastases spread to the bone

A protein vital in determining the organs affected by metastasis has been identified by Swiss researchers. This could lead to the development of therapeutic approaches to suppress metastasis.

Tumors partially destroyed with ultrasound don't come back

Noninvasive sound technology breaks down liver tumors in rats, kills cancer cells and spurs the immune system to prevent further spread.

How tumour cells ‘camouflage’ to avoid detection in the bloodstream

New insights in the metastasis process: tumour cells pass themselves off as platelets to go undetected in the bloodstream, researchers from Granada have discovered.

3D tumour model to unveil metastasis mechanism

Model tumour systems could help explain whether pressure differences can push cancer cells into their surroundings – a basic mechanism behind metastasis.

Study reveals risk of breast cancer spreading to other parts of the body

The risk of early breast cancer spreading to another part of the body ranges from 6% to 22%, according to the first results of a large and detailed global study of metastatic breast cancer presented at the Advanced Breast Cancer Sixth International Consensus Conference (ABC 6). The study also shows that certain women face a higher risk than others, including women diagnosed with breast cancer at…

Pancreatic cancer: New treatment promising for older patients

Pancreatic cancer is a disease of the elderly: the average age of patients is 72. In Austria, about 1,600 people are diagnosed each year. Since pancreatic cancer has no specific symptoms, it is not usually diagnosed until the tumor is locally advanced or has already metastasized. Once the tumor has metastasized, it is usually no longer treatable by surgery or radiotherapy. In addition, the drug…

Stopping the spread

Research sheds new light on pancreatic cancer metastasis

With an overall survival rate of 9% for those diagnosed, pancreatic cancer remains exceedingly difficult to treat. However, the patient's primary tumor typically isn't what leads to death - it is the cancer's ability to evade detection and metastasize to other organs. A team of researchers at the College of Medicine at the University of Oklahoma has published a new study in the journal…

Collagen 'pushing'

Supercomputer illustrates mechanical process of cancer growth

According to the World Health Organization, one in six worldwide deaths have been attributed to cancer; however, these fatalities were not due to initial malignant tumors—the deaths were caused by the spread of cancer cells to surrounding tissues and subsequent tumor growth. These tissues, which consist largely of collagen, have been the focus of a recent collaborative study by a team from…

Metastasis monitoring: CRISPR tool catches cancer 'in the act'

When cancer is confined to one spot in the body, doctors can often treat it with surgery or other therapies. Much of the mortality associated with cancer, however, is due to its tendency to metastasize, sending out seeds of itself that may take root throughout the body. The exact moment of metastasis is fleeting, lost in the millions of divisions that take place in a tumor. “These events are…

Stepstone for new treatments

Regulatory RNAs promote breast cancer metastasis

Cold Spring Harbor Laboratory (CSHL) scientists have discovered a gene-regulating snippet of RNA that may contribute to the spread of many breast cancers. In animal experiments, the researchers could reduce the growth of metastatic tumors with a molecule designed to target that RNA and trigger its destruction. The same strategy, they say, could be used to develop a new breast cancer treatment for…

Pathological regression of lymph nodes

Improved grading system to predict esophageal cancer survival

A group of researchers led by Osaka University established a new pathological grading system to evaluate the therapeutic effect of neoadjuvant chemotherapy (NAC) for metastatic lymph nodes (LNs) removed in esophageal cancer (EC) surgery, demonstrating that the system predicts recurrence and prognosis in EC patients better than conventional systems. Their research results were published in Annals…

Filopodia: The long 'fingers' of highly invasive lung cancer

Tiny finger-like projections called filopodia drive invasive behavior in a rare subset of lung cancer cells, researchers at Winship Cancer Institute of Emory University have found. Adam Marcus’ lab has developed innovative techniques for separating “leaders” and “followers,” subpopulations of tumor cells that cooperate during the process of metastasis. The lab’s new analysis of what…

Lymph node analysis to hunt down metastases

What makes tumor cells turn murderous? The Fraunhofer Institute for Toxicology and Experimental Medicine ITEM is investigating the mechanisms of metastasis formation – and searching for approaches for new treatments in the fight against cancer. Among other things, the research team at Fraunhofer ITEM has developed a method that enables them to analyze entire lymph nodes.

New contrast agent for early diagnosis of brain metastases

A group of researchers led by Leif Schröder from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have found a way to detect metastases in certain types of cancer in the brain at an early stage, using only minimal amounts of contrast agent. To this end, the team uses a synthetic molecule that helps to detect the formation of new blood vessels, producing much more sophisticated…

Promising treatment target

"Partner-in-crime" of colorectal cancer discovered

A protein that helps colorectal cancer cells spread to other parts of the body could be an effective treatment target, researchers from Hokkaido University discovered. Colorectal cancer patients with an immune system-regulating protein called interleukin 6 (IL-6) are more likely to have recurring tumors that can also spread to the liver, according to research published in the journal Cancer…
