Otis SU, Banna GL, Maniam A. The association between paraneoplastic neurological syndromes (PNS) and urothelial carcinoma - A review of the literature. Crit Rev Oncol Hematol 2024; 196:104314. [PMID: 38447785 DOI: 10.1016/j.critrevonc.2024.104314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Revised: 02/10/2024] [Accepted: 02/26/2024] [Indexed: 03/08/2024] Open
Abstract
Paraneoplastic neurological syndromes (PNS) are rare neurological disorders arising from malignancy-triggered autoimmunity, yet their association with urothelial carcinoma remains unclear. This systematic review intends to explore any connection, alongside patient/clinical features and management. A literature search identified 25 cases of bladder and upper tract carcinoma linked to PNS. Overall, while infrequent, a meaningful association between PNS and urothelial carcinoma was found in that 84% of cases met a 'possible'-or-'higher-likelihood' PNS diagnosis. Most cases presented with high-risk PNS phenotypes, predominantly cerebellar syndromes and encephalomyelitis/sensory neuronopathy, ∼17 months within cancer diagnosis/recurrence. Review findings suggest a female preponderance in suspected PNS despite higher male incidence of urothelial cancer. Main treatments consisted of surgery alongside chemotherapy or immunotherapeutics (IVIG and/or corticosteroids), which improved symptoms for a slight majority (60%). Ultimately, while common PNS-associated neoplasms should always first be excluded in suspected PNS, in the absence of alternative causes, urothelial carcinomas do merit clinical consideration.

Paraneoplastic neurological syndromes associated with renal or bladder cancer: case series and PRISMA-IPD systematic review. J Neurol 2023; 270:283-299. [PMID: 36050418 DOI: 10.1007/s00415-022-11356-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 08/24/2022] [Accepted: 08/25/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND The link between paraneoplastic neurological syndromes (PNS) and renal cell and bladder cancer (RCC/BC) is rare and uncertain. Our aim was to clinically evaluate, in light of the updated PNS criteria, these uncommon associations. METHODS Retrospective nationwide cohort chart review study and systematic review of the literature. RESULTS After excluding 5 patients due to the diagnosis of another co-occurrent malignancy, 10/18 patients with RCC and 8/18 patients with BC were identified. A total of 31 cases were previously published, yielding an overall series of 27/49 RCC and 22/49 BC patients. There was a predominance of cerebellar syndromes in both cancers (10/27, 37% for RCC; 9/22, 41% for BC), followed by encephalitis in 9/27 (33%) patients with RCC and encephalomyelitis/sensory neuronopathy in 5/22 (23%) patients with BC. The detection of high-risk Abs was more frequent among BC patients (16/19, 84% vs. 3/13, 23% in RCC, p = 0.0009), Ri antibodies being the most frequent thereof. After applying the updated PNS criteria, patients with BC met highest degrees (possible, probable, and definite) of certainty for PNS diagnosis (20/22, 91% vs. 16/27, 59% in RCC, p = 0.021). CONCLUSION A second neoplasm should always be ruled out before establishing the diagnosis of PNS in patients with RCC or BC. However, while this association remains dubious for most patients with RCC, a casual role is more probable in patients with BC and high-risk antibodies presenting with cerebellar ataxia, brainstem encephalitis or encephalomyelitis/sensory neuronopathy.
