Given the consequences of mistakes, a conservative approach has been considered the best. "It was nature killed her, not me" being easier to stomach than "oops".
The current system does allow for experimentation, but provides a conservative framework for it.
It's huge personal hubris to announce that you know better and they haven't thought it through. Which is one of the things the approach is aimed to protect us from.

June 12: Marshall intentionally consumes H. pylori and becomes ill. He takes antibiotics and is relieved of his symptoms.
That's personal hubris! :)
Which most people seem to think is wrong. The vast majority of treatments that get prescribed by doctors are unproven in terms of safety and efficacy. The main differences between the status quo and a proper experiment is that we're not recording any data or allowing for informed consent.
For many terminal cases, there are still well optimized/studied systems and procedures to prolong and improve quality of life. Unless a patient doesn't qualify for any of those, the doctor is taking a risk on bad odds, a risk most patients can't fully understand.
If the patient's best interests are no longer the primary concern all kinds of shady things become possible.
It's complicated because the costs are borne by a number of different parties: the patient herself, her family, the insurer (private or government).
For example, a patient could live longer but develop disabilities that require extreme measures in terms of treatment and family care, and cost a lot of money. The risks of all these are going to be unknown in very novel approaches, and people with different values are going to vary in their preference.
Understanding those risks and developing guidelines on when to pay for what are one activity of the FDA and major payors like Medicare. A patient and family facing a decision about the value to them in a time of crisis is going to be a lot less informed than those agencies, and it will be a lot easier for a doctor to mislead them (intentionally or not, but doctors aren't immune from over-optimism that their clever ideas might work).
At the same time, it does seem like there should be some protocol where a terminally-ill person can be considered sufficiently informed to take the risk. This is hard, because the risks accrue to individual parties (e.g. the university getting sued in this article) whereas the benefits are diffuse (medicine learns whether induced brain infections improve survival in glioblastoma patients). But without this protocol, we are always going to have stories of patients whose treatments and deaths could be teaching us life-saving lessons if only we could legally do what they want to do.
People can seek pain relief, mental health services, etc. that they might not be able to pursue if they take a risky procedure.
Well, the prognosis is 14 months, so if she lived a year, maybe it didn't work?

Also, there should probably be some rules around peer review prior to starting a procedure that would include reviewing past procedures.
