Cancer-care dataset maps cachexia episodes across 52,236 patients
Researchers also compared four stem-cell-derived blastoid methods with a reference map of more than 14,000 embryonic cells.
Today in brief
Researchers identified 30,938 episodes of cachectic weight loss among 52,236 cancer patients. Episodes tended to occur near disease progression and were associated with worse outcomes across nearly all cancer types studied.1 A computational framework compared four stem-cell-derived blastoid methods with a map of more than 14,000 embryonic cells. None of the models fully reproduced a natural human blastocyst.2

N
In the cancer cohort, 46.63% of patients had at least one cachectic episode, with mean weight loss of 10.45%. Researchers also developed models to predict impending weight loss in lung, colorectal, and prostate cancer, then evaluated them in an independent cohort.1
-
B
Some blastoid models represented the three main blastocyst cell lineages relatively well. Others missed cell types or included cells that could not be confidently assigned to known embryonic states. The team made its reference data and benchmarking tools public. These structures are research models, not human embryos, and cannot develop into one.2
