Regardless of some systematic reviews on exosomes (18–20) and studies on the relationship between exosomes and cancers (19, 21) as well as a bibliometric/altmetric study on the global research output of lutetium-177 PSMA in prostate cancer (22) and the global status of research in prostate cancer bone metastasis (23), there is no altmetric study on prostate cancer-associated exosomes (24). Here, FOLH1 is linked to prostate carcinoma.
