Body can Shield Cancer Cells from Chemo
"Cancer cells can be shielded against the effects of chemotherapy by the body's own stress defences, a study has shown.
The findings add to growing evidence that inflammation, part of the immune response, is linked to cancer.
Scientists studied mice with lymphoma, a cancer of the lymph system, that were treated with a chemotherapy drug.
They discovered some tumour cells found refuge in the lymphoma, an organ where immune cells mature. There they were shielded from the drug by an "anti-stress" immune system molecule generated by healthy cells.
The signalling molecule, interleukin-6 (IL-6), allowed the cancer cells to persist in the thymus."
