How ‘sleeper cells’ in cancerous tumors can be destroyed – Science Daily – 26-Oct-2017
In many metastasized types of cancer, disseminated tumors grow back despite successful chemotherapy.
Researchers from The University of Bern, Switzerland, has now discovered, this is because of isolated cancer cells that survive the chemotherapy due to a phase of dormancy.
If these “sleeper cells” possess specific defects, however, they can be destroyed.
This could increase the efficacy of chemotherapy for certain patients.

Only 5 per cent of people diagnosed with pancreatic cancer are still alive five years later.
The assay uses the binding of gold nanospheres to tumour-derived extracellular vesicles (EVs) captured on a sensor chip.
In a pilot study in 59 patients, it picked up early-stage pancreatic cancer in more than 90 per cent of cases.
Could differentiate between pancreatic cancer and pancreatitis.
