Notes

Added at stage 22: promoted from 'Reported once' (single-article, no diagnostic pair at discovery) because a full-text synthesis with extracted data exists in parsed-therapy.xlsx -- PMID(s): 41946831. Target/mechanism, clinical application, indications, approval and precursor fields still need per-agent research and are intentionally left empty. Stage set/updated at stage 23 from PMID 41946831: 'Radioimmunotherapy was done in nude mice bearing trastuzumab-resistant HCC1954 (high HER2-density), T-DM1/trastuzumab-resistant JIMT-1 (medium HER2-density) and MDA-MB-468 (negative control with very low HER2-density) xenografts.'.
