That's particularly useful for pancreatic cancer, if it's accurate, reliable, cost effective, and practical in the real world.
It’s not, though and that’s the issue.
False positives are at least as dangerous as false negatives and AI solutions like this have massive problems with over diagnosing.
EDIT: It’s really fun to have a bunch of home-bound tech workers try to talk down to me about the science behind and practice of medicine.
Absolutely 100% wrong.
In pancreatic ductal adenocarcinoma, a false positive means a follow-up scan. A false negative means death, the 5-year survival is near zero once it's caught late, but exceeds 80% when caught early.
In the study, the radiologists' lower false positive rate is achieved by missing 78% of cancers. That's not a safer trade-off, it's just a different way to fail. "Overdiagnosis" also requires a disease that might not have harmed the patient, PDA doesn't have a harmless form. Every missed case is a lost life while every false positive is an extra doctor's appointment.
This system detects twice as many cancers and was flagging them, on average, 675 days (nearly 2 years!) before clinical detection.
You selected a single pathology which supports your otherwise specious and false argument.
Be better.
If I'm wrong, then feel free to support your position with evidence or an argument showing that my statement was specious.
I linked the, peer-reviewed, paper which contains the data that supports my statements on the topic.
You've made two conclusory statements and immediately resorted to insulting comments when challenged.
There is not a single aggressive pancreatic cancer where a false negative is more dangerous than a false positive.
Percutaneous biopsy has a mortality rate of approximately 0.2% even relatively non-malignant pancreatic cancers (say Solid pseudopapillary neoplasm) have 10-year survival rates in adults of around 88% and that number is from cases which received surgical intervention and chemotherapy something that would not happen with a false negative.
So even in the worst case, the false negative multiple times more deadly. A false positives' most likely outcome is pancreatitis from the biopsy procedure.
They selected the pathology that’s the topic of the post to support their on-topic argument. Be better, indeed.
In other words: not useful at all. (Didn't read the article because it already misuses the AI acronym in the title, indicating it was written by some idiot with nothing to say)
Article actually describes it well enough, how scientists trained a model on data from CT scans of patients who were treated for other conditions some time before being diagnosed with pancreatic cancer.
In my first sentence, I was referring to the combination of adjectives in the question by previous commentor. No one in today's health care systems is gonna pay preemptive screenings for saving peasant lives like yours or mine.
There are healthcare systems in the world other than the one in the usa
Yes, but all of them are worsening in the interests of profit, in case you weren't following the news. Germany is just scrapping skin cancer prevention, thanks to our corrupt fucks in government.
If course you do - if the cost of treating the patient down the line is going to cost you more. Public health systems have a vested interest in healthier citizens.
The thing is providers of care like to make a profit though, and profit = money = influence on healthcare policies. Healthcare policies are not made solely with cost efficiency in mind, but rather to redistribute wealth from insurance payers to those who provide services. If that means a couple ten thousand of us peasants die a preventable death, then that's a sacrifice they are willing to make.
Where you live maybe. The NHS is centrally funded through taxation.
That does not contradict anything I said.
Problem is they are probably from the US which doesn't really have a public healthcare system.
Even in the US with private health insurance, those providers will pay for screenings that can save costs by catching something early. Sometimes that might be legally mandated, other times it’s based on cost/benefit. It all varies from plan to plan, but the more common a disease is the more likely they’ll pay for at least a low-cost initial screening.
You used the AI acronym in the same way, so I'm confused by your arrogant sounding statement
Did I though? Are they using a model with any kind of abstraction layer that actually understands relationships between objects?
Yes and yes.
These are questions that you wouldn't have to ask if you didn't smugly decide that you didn't need to read before contributing your opinion.
If you can't be arsed to read the article, here's the peer reviewed paper in the British Medical Journal: https://www.science.org/doi/10.1126/science.adz4433
AI is different from LLM, you disingenuous fuck.
Did it get its knickers in a twist?
Hey weirdo why did you attack someone out of nowhere?
Fuck off if you can’t be an adult and hold your big AI feelings
Learn to troll, grandpa.
