Unfortunately I missed the Horizon program.
However, some of you might like to know how the "kemotherapy" works in the case of Lukemia.
The terminology may be wrong because the term of "kemotherapy" seems to mean chemical treatment.
Lukemia is caused by cancerous reproduction of the white blood corpusles. The solution is actually quite crude.
First a bone marrow ( when the white bits are made ) donor is found who matches the patient. A core sample is taken containing the marrow and stored.
The patient is then exposed to whole body atomic ( ionising ) radiation. This causes vomiting and the usual symptoms of radiation exposure. The interesting thing is that the radiation level kills the cancerous cells which are more susceptible to radiation. It also causes the loss of hair !!!
The patient is then barrier nursed because they have no immunity to infections as the white blood cells ( leucosites ) have been killed.
After a few days, the donor's bone marrow is then injected into the blood stream and it finds its way into the bone marrow and if all goes well it then reproduces white blood cells and the patient returns slowly to fairly normal health.
The long term response is not yet known and the life expectancy is not very high as many patients have remissions within five years. One specialist I spoke to told me she was going to dinner with one of her first patients that she had treated 10 years before. It sounded as if that was a more successful treatment as the average life expectancy after treatment is probably still only five-six years.
I thought that it was nice that the patient kept in touch with the specialist who had kept him alive for the last 10 years.
