Sometimes, I think data from a clinical trial can be massaged and polished into a bright shiny object that tells you little. This article, about use of ipilumimab (Yervoy--Bristol Myers Squibb) in mCRPC) seems like one of those instances. What do you think?

Clinical trial tyros--what do you think?
I wrote about the same trial (below) but had a different understanding about it. Media often try to spin research results to get a more sensational story.
prostatecancer.news/2016/08...
Sometimes it seems to me that BMY is trying desperately to make the case for Yervoy. The article is behind a paywall; evaluating a "piecewise hazard model" in any case is above my pay grade.
“Several molecular markers, such as tumor mutational burden and mismatch repair deficiency, have shown little correlation with response to immunotherapy.“
This is just wrong.
TMB has been FDA approved for Keytruda across multiple cancers regardless of location ( June 16th 2020).
The latest research would indicate that several biomarkers , MSI-H, dMMR, PL-L1, TMB hypermutated ( >10), TMB ultramutated (>100 )when combined with MSI-L ( POLE and POLD1), CHEK-1 and possibly HRR ( BRCA 1/2 etc) can strongly suggest immunotherapy.
If someone has a couple of these then that person should get access.
It is irresponsible that the trial should make a statement like that.
In fairness, this article does not mention pembrolizumab (Keytruda); nevertheless, sweeping statements like the one you cite are not helpful--I agree.
It did not mention it by name but it dismissed all checkpoint inhibitors with an incorrect statement. It would make you doubt the people writing the report if they are so out of date with immunotherapy treatments. I do not think it was malicious but does appear careless. Thank you for bringing it to our attention.

It seems a good study.
The authors never mentioned:
“Several molecular markers, such as tumor mutational burden and mismatch repair deficiency, have shown little correlation with response to immunotherapy".
The author of the article, Charles Bankhead (senior editor) did.
Tango 65
That better explains the statement. It was difficult to accept that scientists would make such a comment.
It goes to the heart of Dentaltwin’s premise that some articles are massaged to increase the impact.
That is serious when it comes to peoples health.
tango65 states that that comment is nowhere found in the source paper, so it may be Bankhead, or another source. Bankhead makes no disclosures of interest, but the study was clearly supported by Bristol Myers Squibb.
To p3d1,
Holy Chit..... don't tell that published data is massaged for publication. Next you'll tell me the tooth fairy wears dentures.....
Good Luck, Good Health and Good Humor.
