Tumor treatment is the mainstay of therapy for paraneoplastic neurologic disorders (PNDs), but it is only effective in some cases and other treatment options are limited. To evaluate the short-term use of a combination of prednisone and tacrolimus for acute neurologic worsening in PND in which intracellular antigens are targeted. Retrospective single-center case series of patients with PND treated with tacrolimus. The Rockefeller University Hospital, a research hospital in New York, New York. Twenty-six patients with PND with high titer (≥1:1000) anti-HuD, anti-Yo, or anti-CRMP5 auto-antibodies were enrolled. Patients were referred from Memorial Sloan-Kettering Cancer Center or self-referred. Two patients discontinued intervention owing to adverse events. Patients were treated with tacrolimus, 0.15–0.30 mg/kg per day, in 2 divided oral doses with 60 mg per day of oral prednisone tapered off during 1 to 4 weeks. The primary outcome measure was median survival. Neurologic examinations before and after treatment as well as adverse events are described. Median survival time was 52 months from time of diagnosis. Some patients experienced neurologic improvement that was functionally meaningful. The incidence of adverse events was similar to that generally reported with tacrolimus. A short course of prednisone and tacrolimus to target central nervous system T cells in patients with PND with acute neurologic decline in which intracellular antigens are targeted was well tolerated and warrants further study.
