In a breakthrough for cancer research, scientists at the Memorial Sloan Kettering Cancer Centre (MSK) have uncovered new insight into how malignant cells elude the immune system. The team focussed on a trait known as chromosomal instability, which allows cancerous cells to escape immunological defences and metastasise within the body. The findings have unveiled exciting new treatment options, with scientist Samuel Bakhoum saying it tells researchers a lot about the mechanics and capabilities of cancer cells.
“The elephant in the room is that we didn t really understand how cancer cells were able to survive and thrive in this inflammatory environment, says Bakhoum, a physician-scientist at MSK.
New treatment approach inspired by how cancer cells evade immune defenses: Study ANI | Updated: Jan 02, 2021 23:05 IST
Washington [US], January 2 (ANI): During recent study scientists have discovered how immune defences are evaded by cancerous cells, leading to a new treatment approach towards the treatment of the disease.
Cancer cells are known for spreading genetic chaos. As cancer cells divide, DNA segments and even whole chromosomes can be duplicated, mutated, or lost altogether. This is called chromosomal instability, and scientists at Memorial Sloan Kettering have learned that it is associated with cancer s aggressiveness.
The more unstable chromosomes are, the more likely that bits of DNA from these chromosomes will end up where they don t belong: outside of a cell s central nucleus and floating in the cytoplasm.

Cancer Discovery.
Cells interpret these rogue bits of DNA as evidence of viral invaders, which sets off their internal alarm bells and leads to inflammation. Immune cells travel to the site of the tumor and churn out defensive chemicals. A mystery has been why this immune reaction, triggered by the cancer cells, does not spell their downfall. The elephant in the room is that we didn t really understand how cancer cells were able to survive and thrive in this inflammatory environment, says Samuel Bakhoum, a physician-scientist at MSK and a member of the Human Oncology and Pathogenesis Program.
