Malignancy in Guillain-Barré syndrome:A twelve-year single-center study


The relationship between Guillain-Barré syndrome (GBS) and malignancy is uncertain. We retrospectively analyzed data of 118 consecutive patients admitted with GBS from Birmingham, U.K. (2001 − 2012). We calculated relative cancer risk using different definitions and determined characteristics of malignancy-associated GBS. Malignancy was globally commoner in our GBS cohort compared to the general population (odds ratio: 2.08; CI: 1.06–3.71; p = 0.036). However, this was unconfirmed if paraneoplastic criteria were applied. GBS patients with cancer were significantly more likely to be older (p = 0.043), hyponatremic (p = 0.037) and demonstrate more axonal loss (p < 0.05). Cerebrospinal fluid (CSF) protein levels were lower in the malignancy group (p = 0.002) and neurological improvement less likely (p = 0.023). In-patient mortality was significantly higher in patients with malignancy (p < 0.01). We conclude global cancer risk is higher in GBS than in the general population, although definition-dependent. Malignancy requires consideration in elderly, hyponatremic subjects with normal CSF protein, severe axonal loss, who fail to improve post-treatment.
