The appearance of a paraneoplastic neurological disorder (PND) with Hu-antibodies, often before tumour detection, together with spontaneous tumour regression in a few patients, suggests that immune responses to HuD, possibly mediated by cytotoxic T-cells, could be beneficial to the patient.1 Nevertheless, in previous retrospective studies, survival in Hu-antibody-associated PNDs (Hu-Ab/PNDs) in general was similar to those in patients with small-cell lung cancer (SCLC) without neurological illness.2 3
Here we studied, for the first time prospectively, tumour outcomes in a large series of patients with Hu-Ab/PNDs, comparing with contemporaneous patients with SCLC without neurological symptoms.
Written consent was obtained from all patients. From July 2012 to June 2015 prospectively we collected all serum samples that were positive for Hu-antibodies at Oxford University Hospitals as part of routine diagnostic testing via referral from any of England’s 152 acute hospital trusts. Diagnostic categorisation of associated PNDs…
