HER2-Positive Breast Cancer Linked to a Rare Immune-Related Neurological Syndrome

Patient Info: Anonymized, Female, 40s

Biomarkers: HER2-positive in both foci; one focus ER-negative/PR-positive with Ki-67 45%; second focus ER-negative/PR-negative with Ki-67 35%; anti-Yo antibodies positive in serum and CSF; tumour-susceptibility gene panel negative

At 1 year, she had completed trastuzumab, continued tamoxifen, and had no evidence of recurrent breast cancer; intensive rehabilitation improved her mobility, although balance and right-sided neurological deficits persisted.
