To safely destroy a cancerous tumor, bacteria are injected directly into the tumor, along with a cofactor. The bacteria are genetically altered to depend upon the cofactor for reproduction. The cofactor is typically a large protein molecule with a low diffusion rate in tissue. It may be deposited into
the tumor in microencapsulated form, so that it is released over a long period of time. Destruction of the tumor is by direct action of the bacteria on the tumor, or by immune response. Reproduction of bacteria outside the tumor is suppressed by absence of the cofactor.

I know nothing of this,however if it's a start + |
|

Actually, [Dimandja, thanks for the link] bacteria were used way back in the 19th century to destroy tumors. My invention here is in the use of cofactors. It seems to be novel, at least according to Google, where I cant find anything similar. (But then, its late, and Ive been drinking...but only one bottle of cheap merlot.) |
|
|
Hmm like this idea. Perhaps might be easier to engineer them to require a cofactor to absorb nutrient. Perhaps not even requiring genetic engineering but perhaps just a chemical coating/chemically treated cell walls. |
|
|
Hmm, if they are just coated they shouldn't be allowed to reproduce... |
|
|
If you can engineer bacteria in this way, isn't it equally easy to alter them (or other agents) to simply destroy cancerous cells and leave healthy ones alone? This appears to be what the researchers in the linked story have done. |
|
|
[Monkfish] Dimandja's link is from a number of years ago. The altered bugs did not work out as planned.
A more recent quote -- "Yet, the bacteria alone weren't sufficient to stop tumor growth altogether, Pawelek says in an interview with WebMD." |

Targeted MRSA - type organism ? |
|
|
An interesting variant on the "magic bullet" idea. |
|
|
I don't like the sound of this. I'm so sceptical of bacteria I'm afraid to drink the dairy-produce-cultures that are in fad at the moment. |
|
|
Give me toxic chemicals, high powered X-rays and the scalpel any day. |

Odd, round here it's greated with panic-stricken screaming and the receeding sound of running feet. |

And so, boys and girls, with those stirring words, Jinbish died. He was a true patriot for the AMA. |

<aside> I wonder, if you operated on [DrCurry] and removed the malignant bits, would there be anything left </aside> |
|
|
pluterday, you sort of answered the afterthought instead of the question there. I wasn't under the impression that they'd cured cancer; I probably would have heard something about that. It's the fact that they chose that approach that's significant. This is an interesting idea (+), and it would probably do no harm to try different things, but it seems more complicated and dangerous than the existing lines of research. |
|
|
But of course they cannot admit that theyve cured cancer. Anyone who does that is promptly assassinated by the consortium of radiologists, oncologists, and others who are collectively know as
ahhh
gggggg
<connection lost> |
|
|
Don't get me wrong [pluterday] - I'd *love* to have a good alternative to chemo + radio + surgery. Rumour has it they can be quite an experience (but on the plus side you meet alot of nice nurses). |
|
|
But, I fail to see how the bacteria can be any better at destroying tumour than the correct use of chemo. |
|
|
Assuming that the bacteria only thrive in the presence of a reagent, you must target the reagent precisely. But this whole targetting thing is the problem. If we could target an area for the chemotherapy then the good ol' toxic cocktail would destroy/inhibit tumour and leave healthy cells alone. So what is the advantage of using the bacteria? |
|
|
Furthermore, how would this work in the case where a cancer exists as multiple tumours? Would you flush the patient with bacteria + reagent? |
|

Dear Mr. Jinbish,
I am sorry to have to inform you that Dr. Pluterday has had an accident. A broken neck. Once of those spontaneous things, apparently.
As her assistant, I have to tell you that Dr. Pluterday was quite mad. Manuscripts on time travel. Cancer cures. Just rubbish like that, all piled to the ceiling. I will have to burn it all, I suppose.
Sincerely,
Dr. Pluterdays assistant

<obscure movie reference>But I'm afraid the formula to add bubbles to beer was lost. All we have left is this curious E=mc^2 equation, which appears to be quite absurd. Everybody knows that matter and energy have nothing in common...</omr> |

I saw this on a programme one time, where a cat had got an infection on its ear and rather than the bacteria causing the ear to drop off, it was the cat's own immune response that started to destroy the tissue of the ear. So rather than using bacteria to destroy the cancerous cells why not use your own bodies immune response, (of course you would have to put a lot more thought into this than I did, I dont know which type of bacteria would do this or even if a human immune system would even have the same effect as a cats). |
