YouTube explainer by Dr. Charles Mok (uploaded 2024-02-21) describing liquid biopsy: its origin as monitoring known cancers (e.g., ovarian), how tumor DNA signatures in blood can indicate remission or residual disease, approximate current costs (speaker cites about $650 at Henry Ford Hospital and about $950 elsewhere), that liquid biopsy can detect several tumor types across stages, and the speaker's claim that when combined with MRI and regular screening, dual-negative results imply >99% certainty of not having cancer.

Questions this video answers

Approximately $650 (Henry Ford Hospital) and about $950 (speaker's quoted case).

More than 99% certainty of not having cancer when both MRI and liquid biopsy are negative.

Chapters

So liquid biopsy originally was where we identify somebody had a certain type of cancer and we get the DNA of that cancer and then we treat the person. Let's say it was ovarian cancer or something. And then we do blood tests to see if there's any remnants that cancer still floating around so we know if they're in remission or not. Over time, they got enough of these signatures, enough these thumbprints of cancers where now you can just get a liquid biopsy, redraw your blood anywhere from 650. I've heard Henry Ford Hospital locally here is about 650. We get the case for about 950. It's reasonably cost effective. It's not that good yet, but it's the best thing there is for liquid biopsy. It picks up several different tumor types that could be very early stage or late stage. So you combine your regular screening with MRI and liquid biopsy, and it's negative. You probably don't have cancer with more than 99% certainty.
