a illness that that fights cancer?

Question

ok, so i was on the internet and i read somewhere that injecting a certain sickness right into the cancer will cause the cancer to shrink and the more you put in the more it shrinks and usually it will disappear entirely. it also said that because nobody know why this happens it is never used. it was only in an experimental stage. can anyone tell me what this specific illness was and who experimented with it?

Answer 1

There is research and clinical trials going on trying to use viruses in this manner. This isn't new. It just hasn't worked yet entirely, but there are some promising trials currently in progress.

Perhaps the one you have heard about is Reolysin (a living virus that breaks down cancer cells)? Already in Phase II trials and showing effiacy in some tumor types.
http://clinicaltrials.gov/ct/show/NCT00503295?order=1

There are a number of these types of adenoviruses which are being used in hopes of killing the tumor while sparing normal tissue (the virus will replicate only in the cancer cell thereby shrinking or killing the tumor . . in theory).

Answer 2

Let me give you a specific example.

There is a research being done now at Duke University to use a modified polio virus against brain tumor cells. The rationale is this. The polio virus attacks motor neurons (nerve cells). Neurons have the surface antigen signature that matches the receptors on the polio virus. The polio virus also does not mutate much. This makes it theoretically ideal to target brain cells.

You may ask what about the healthy brain cells? Well, scientists can engineer a genetic payload for the virus. This engineered payload will replace the genetic material normally part of the polio virus (so the patient will not get polio).

Because brain cells normally do not divide and cancerous brian cells do multiply, a genetic payload that causes replication products to be faulty may be able to kill the cancerous cell. For example, a genes that shutdown production of DNA polymerase or synthesis of thymine necessary for cell division may be used as gentic payloads. It's still in the very early phases of research.

Note, this example approach cannot be taken with cells that do normally divide as it will kill them too. If they can make this approach work, perhaps they can do something similar for sarcomas of some muscle tissue (heart).

I'm not as familar with other approaches. However, I have read adenoviruses being used. Adenoviruses are often used as vectors in genetic engineering because they are relatively easy to work with.

A problem with virus. They also initiate an immune response. Therefore, they will eventually be rendered useless soon after infection. Subsequent infections will not be effective because of the developed humoral immunity (antibodies) developed.

Answer 3

There are several viruses that are being tested at the moment.

There is one for brain tumours and another for colo-rectal cancer that I am aware of.

Try typing "cancer fighting viruses" into Yahoo's search engine, there are more links than I can list here!
