Added from reverse module search (stage 6); 4 article(s) with Y-90. Stage set/updated at stage 23 from PMID 41599688: 'Therapeutic evidence shows encouraging tumour retention and safety profiles for agents such as [177Lu]Lu-FAP-2286 and [90Y]Y-FAPI-46, while α-emitting radiotracers (e.g., [225Ac]Ac-FAPI-04) demonstrate potent antitumor effects in preclinical models.'. | Stage 28: added indication(s) onc-sarcoma from consolidated missing-rubric review. | Stage 30 (2026-09-18): Stage was 'early-stage clinical evidence / investigational'; normalised to 'Clinical research', original wording kept here.
