Good thoughts for those who lost people they care about to cancer, know someone with cancer, have cancer or may in the future have cancer.
Jackie made some really good comments that I also agree with.
I've avoided commenting in this thread mostly since I work in cancer research and have a different view of things. I will make a few comments and leave it at that, but feel free to ask my opinion for anyone who is interested.
The need to have failed the standard of care before entering into a clinical trial is, IMO, important even though it does mean that any drug worth its weight will need to be that much better to help patients that are that much sicker. It's there because we live in a society where we are comfortable trusting a federal agency to deem drugs safe and effective. You would have a hard time getting patients to take a drug initially without any indication that is has worked, whereas with known treatments, you have at least some chance of treatment (not without risk and side effects, but still). Once a clinical trial has shown efficacy, even if the trial is not complete, it can be halted and the new drug generally available to all the participants.
Our current therapies leave a lot to be desired, I understand that. Cancer is a terrible disease. But there isn't ever going to be one cure. Each and every cancer is different and even within one type of cancer, there are tumors that arise from different cells of each organ, necessitating a different type of treatment. Finding a drug is part of the battle, and determining which cancers this drug will work on is the other part. For example, breast cancer. Cancers positive for BRCA mutation respond differently than ones that aren't. Well, we don't have markers such as BRCA to test for each cancer, drug or therapy. As another example, I can think of one treatment that can effectively cure cancer for maybe 10% of the patients who receive it. The other 90%, it makes terribly ill and many will die from the treatment, let alone the cancer. So far, I don't know of a great detection method for figuring out why those 10% are special, and only give it to them. We work every day to find a way to increase efficacy to lower the side effects but we're just not there yet.
