I read an article about it too. The hope is to reverse drug resistance, as reported in the magazine Nature.
Here are some words from the free to use version of the magazine. After I read it a few times it began to be sort of understandable.
'Whether myeloid inflammation drives prostate cancer progression in humans remain unclear. Herein we show that inhibition of myeloid chemotaxis can reduce tumour-elicited myeloid inflammation and reverse therapy resistance in a subset of metastatic castration-resistant prostate cancer (mCRPC) patients. We show that higher blood NLR reflects tumour myeloid infiltration and tumour expression of senescence-associated mRNA species including myeloid chemoattracting CXCR2 ligands.'
