Ethanol: A Lethal Injection For Tumors (acsh.org)

Scientists have known for some time that ethanol can kill cancer cells, but several limitations held it back from becoming a broadly used treatment. A team at Duke University has recently developed a new type of ethanol solution that can be injected directly into a variety of tumors to potentially offer a new, safe, and cheap form of cancer treatment. From the article: The authors were already aware of a therapy known as ethanol ablation. If ethanol (the type of alcohol found in your favorite adult beverages) is injected into a tumor, it destroys proteins and causes the cells to dehydrate and die. Ethanol ablation is used to treat one type of liver cancer, and its success rate is similar to that of surgery. Better yet, it costs less than $5 per treatment. Ethanol ablation faces several limitations. First, it only works well for tumors that are surrounded by a fibrous capsule. Second, it requires large amounts of ethanol, which can damage nearby tissue as it leaks out. And third, it requires multiple treatments. To overcome these hurdles, the authors mixed ethanol with ethyl cellulose, creating a solution that when injected into the watery environment of a tumor turns into a gel, which remains close to the injection site. After they practiced injecting their solution into imitation tumors (what they called "mechanical phantoms"), the authors turned to a hamster model. The team induced the formation of oral cancer (specifically, squamous cell carcinoma) in hamster cheek pouches by rubbing them with a carcinogen called DMBA. After about 22 weeks, tumors (without capsules) formed. In the control group, tumors were injected with pure ethanol. The results were not good. After seven days, 0 of 5 tumors regressed completely. (Tumors injected with a large amount of ethanol -- four times the volume of the original tumor -- performed better: 4 of 12 regressed completely.) The results for the ethanol gel were far superior. After seven days, 6 of 7 tumors regressed completely. (By the eighth day, all 7 tumors were gone, for a cure rate of 100%.)

      "Ethanol ablation is used to treat one type of liver cancer" -- oh the irony.

      I suppose it's ironic in cases where the liver cancer was caused by alcohol, but that's not normally the case. Liver cancer is usually secondary, having metastatized from cancer elsewhere in the body. And the reason ethanol ablation is used on that particular type of cancer is precisely because the liver -- unlike most tissues in the body -- can tolerate ethanol leakage, since breaking down ethanol is one of its functions.

      So, really not very ironic.

    I'll wait until they've done a much larger properly blinded test.

    If I had terminal cancer I'd take highly experimental over certain death, you're only risk averse when it usually ends well. When it'll end badly you're ready for any "Hail Mary" save. Not that I'd try obvious snake oil and superstition, but any reasonable experiment I'd be in on... seems like the worst that can happen here is that you get mighty drunk, granted I've had bad hangovers but I'd rather go out drunk as a skunk than wait for the cancer to get me.

    Well you can paint inject glue around the tumor, and you can restrict cancer blood vessels to increase poorer supply for hungry tumors. You can inject into the middle, and as it shrinks - repeat the process - as already done with radioactive mini beads, or injecting liquid nitrogen.
    I'm sure time release capsules has been researched. Then there is powdered alcohol to play with. See black salve.

    Also, from what I've heard (disclaimer: oncology is not my speciality), patient close to the end also tend to have altruistic views :
    even if it doesn't end up saving *them personally*, taking an experimental treatment might still help advance the science and who knows who might end up being saved later thank to what was learned by this experimental treatment.
    Some are thus happy to save any live, even if it ends up not being their own.

    The doses needed to be injected without this "gel improvement" are usually massive.
    It's not only getting drunk/hangover from what leaks in the general blood stream system.

    It's alcohol still being at very high level nearby the tumor and destroying healthy tissue and organs around the tumor
    (painful, problematic and potentially dangerous).
    Akin to a badly calibrated radiation therapy.
    i.e.: you're literally burning the patient in this failure mode (though think "chemical" burn rather than garden variety of fire)

    The potential of this gel is similar to what computer modelling helped improve radiation therapy.
    Making sure the treatment arrives exactly where it should, and is only working where needed.

      What on earth makes you think that computer modeling makes the radiation only arrive exactly where needed? That's just not how it works.

      Very true. Sometimes people have serious side effects resulting from radiation burns. I'm not sure how much that has improved over the years, but it definitely was a problem with beam radiation at one time.

      That said, in theory, there's no reason it couldn't be exact if you used directed high-power EM instead of ionizing radiation. You could use constructive interference in the same way that they do when breaking up kidneystones, only instead of shattering something solid, you heat up the tumor to the point that the cells die. It would basically be like creating a microwave oven hot spot right where the tumor is, and the rest of you would just get a little warmer.

      I've heard presentations on functionalizing iron nanoparticles with anti-tumor antibodies, injecting them, and then putting the patient into a high-field NMR machine. Suddenly, you can see every single cancer cell, not just big clusters, and if you turn up the RF, the iron nanoparticles wiggle like water in a microwave.

    Very likely to be idiotic, ineffective, and dangerous to patients and other living things!
    As a professor of anesthesiology and neurological surgery, I have seen on rare occasions,
    surgeons pour absolute alcohol (100% ethanol, i.e., 200 proof) into the bed of an excised
    tumor in the abdomen. It works poorly and is dangerous. There are no decent studies
    demonstrating improved outcome for the patient. Indeed the alcohol is toxic not just to
    tumors, but to ALL tissue and to ALL cells. It denatures (unfolds) proteins. Thats why histologists and pathologists use it to "FIX" tissue for microscope slides. What it does to the
    stomach and liver is a story for another day.

    I have also seen an idiot surgeon use an electrosurgical (Bovie) cautery on a bleeding blood
    vessel right after pouring in the EtOH. Woosh! There went the patient in a ball of blue flame!
