Apparently. I'm not an expect, but it's what I have encountered elsewhere.
Still great news! But not quite as revolutionary as the headline implies.
City of Hope thinks they've found a chemotherapy that's "able to kill all solid tumors","in more than 70 cancer cell lines".[0]
According to the National Cancer Institute[1], there are "more than 100 kinds of cancer". They're listed here: [2] Some of those cancers are soft tissue, so they aren't affected by this treatment.
I didn't know what a cancer "line" was, so I looked it up. "Cancer cell lines are valuable in vitro model systems that are widely used in cancer research and drug discovery."[3] So, they're not cancers in people, but cell cultures they can test drugs on.
This probably doesn't give you much more information than you already have, based on what you heard elsewhere, but I learned enough to figure maybe it would help someone else, too.
Whether this'll work in people, I guess we'll find out when they start the Phase 1 clinical trial. If you, or someone you know think you might benefit from this, there is a link to sign up for Phase 1 trials.[0]
It appears to have worked in pre-clinical trials, so they have tested this to make sure it doesn't kill people outright, the same way it does cancer cells.[4]
