To keep things in perspective, in oncology the current success rate of treatments that enter trials is just 5%! See http://blogs.sciencemag.org/pipeline/archives/2016/06/02/are....

Immunotherapy is indeed the most promising approach to cancer therapy so I'm optimistic, but the odds of success here are 1-in-20 if this is an average study, or perhaps 1-in-5 at best.

>The only way to make real inroads in control of cancer is to crush down the cost of addressing different cancers, making it a small project rather than a whole new research initiative each time around.

Agreed. And while this study's methods wouldn't be cheap per se, RNA-based methods combined with whole genome sequencing of tumors are much more cost (and time) efficient methods than approaches that require antibodies or chimeric proteins. I believe that these methods, in combination with immunotherapy, are the best candidates for future cancer therapy.

Stupid/insensitive question: what if cancer were a species "feature" earned through evolution that helps reap people who made it through their reproductive years without accident or disease but are now more hindrance than help to the species?

Most animals can get cancer, even invertebrates. Not to say your hypothesis isn't close to reasonable, but you'd have to strike the "species" part.

I would argue that cancer is more of a consequence of aging, genetics, and environmental factors and not a "feature". Cells have evolved multiple mechanisms to prevent rampant and uncontrolled growth. With cancer these mechanisms are perturbed through genetic alterations due to "bad luck" or the consequences I mentioned previously.

Not sure if that's intentional, but the BioNTech series of trials for melanoma been called MERIT (this particular incarnation is Lipo-MERIT).

Because evolution doesn't work on a species level, it works on a gene level. Genes that help propagate themselves spread more. A cancer causing gene would almost certainly be selected against, vs a gene that caused you to live longer and have more children - and spread more copies of itself.

The reason people die is not because it's better for evolution. It's because evolution simply doesn't care about maximizing life expectancy. Most organisms die long before they get cancer, so the fitness of a gene that prevents cancer is pretty small.

Paywall: I read this as an ability to help in immunotherapy which works like a vaccine. I really am interested in what types of cancer this works with the strongest effect. They list soft tumors in Lungs. The bellow citation seems to show that these are something that could work on all cancer types and is cheap. These are exciting times. Now it will be another 5 years till we see this even in a trial for children? (S…

Out of curiosity, what brain cancer does she have? I had a Grade II astrocytoma in 2013, came back in Sept 2015 as Grade III. Currently undergoing chemo and feeling fine (25 years old).

Earlier quoted context omitted.

It's very exciting, but as these therapies become more successful, we're going to have to tackle the adverse reactions both acute, and chronic. Granted, you're surviving cancer so that's not the primary concern, but it will be a concern.

Well that is the Number One Reason why they are going immuntheraphy the side effects are minor compared to Chemo and Radiation. This is your own body fighting the cancer.

I don't think "Minor" is accurate. A good friend just went through this to beat a strange form of metastatic blood cancer, and he was in the ICU for a week as a direct result. (and essentially comatose) It was worth it, since he went from, "Plan your death" to, "Full remission!". Still, he was strong going in, a lot of people would have died.

Right now, there's still a lot of art to the balance between having your immune system fight hard enough to kill the cancer, without setting off a cytokine storm that kills you. There's also the issue of longer term autoimmune complications, which I suspect will turn out to be the "secondary cancers" of the immunotherapy world.
