Fasting may improve cancer chemotherapy

March 31, 2008 -- Fasting prior to cancer chemotherapy treatment may significantly enhance the cancer-killing effects of the drugswhile protecting healthy cells from damage.

A new study suggests starvation induces a protective shield around healthy cells, allowing them to tolerate a much higher dose of chemotherapy

Researchers say cancer chemotherapy can kill as many healthy cells as cancerous ones, but inducing temporary starvation increases the cells' resistance to stress, which may allow doctors to use higher doses of current cancer chemotherapy treatments to make them more effective…

In tests with live mice, of 28 mice starved for 48-60 hours before chemotherapy, only 1 died. Of 37 mice that were not starved prior to treatment, 20 mice died from chemotherapy toxicity…

Researchers say genetic cues prompt starved healthy cells to go into a hibernation-like mode that produces extreme resistance to stress. But cancerous cells don't obey those cues and remain stuck in growth mode.

  1. Very interesting. That study was from March 2008. I haven't seen any more on that.
