Cancers, Vol. 11, Pages 687: Pretreatment Cancer-Related Cognitive Impairment—Mechanisms and Outlook Cancers doi: 10.3390/cancers11050687 Authors: Brennan Olson Daniel Marks Cognitive changes are common in patients with active cancer and during its remission. This has largely been blamed on therapy-related toxicities and diagnosis-related stress, with little attention paid to the biological impact of cancer itself. A plethora of clinical studies demonstrates that cancer patients experience cognitive impairment during and after treatment. However, recent studies show that a significant portion of patients with non-central nervous system (CNS) tumors experience cognitive decline prior to treatment, suggesting a role for tumor-derived factors in modulating cognition and behavior. Cancer-related cognitive impairment (CRCI) negatively impacts a patient’s quality of life, reduces occupational and social functioning, and increases morbidity and mortality. Furthermore, patients with cancer cachexia frequently experience a stark neurocognitive decline, suggesting peripheral tumors exert an enduring toll on the brain during this chronic paraneoplastic syndrome. However, the scarcity of research on cognitive impairment in non-CNS cancers makes it difficult to isolate psychosocial, genetic, behavioral, and pathophysiological factors in CRCI. Furthermore, clinical models of CRCI are frequently confounded by complicated drug regimens that inherently affect neuroco...

We report herein incidence and clinical features of hyperacute onset PCD, a vertebrobasilar stroke mimic. We performed a retrospective analysis of all suspected PCD cases referred to the Udine University Hospital between 2009 and 2017. Our center provides the only neuroimmunology laboratory for three provinces of the Friuli-Venezia Giulia region, Italy (983,190 people as of January 1, 2017). Inclusion criteria were (1) abrupt onset of neurological symptoms; (2) initial consideration of a vascular etiology; (3) final diagnosis of "definite PCD." We also carried out a systematic review of the literature in order to...

We report a case of a patient with chronic inflammatory rheumatism, psoriasis and Hashimoto thyroiditis and subsequent appearance of static and dynamic ataxia and episodic memory deficit who was diagnosed as PLE combined with small cell lung cancer (SCLC). Diagnoses: The diagnosis of SCLC was made with EBUS-TBNA of a mediastinal lymph node. Interventions: Whole-body 18F-FDG PET/CT was performed for the initial staging of SCLC, in the planning of radiotherapy treatment, to evaluate therapeutic response and in the follow-up. A dedicated brain scan was included to the same PET session. Whole-body contrast enhanced compu...

(University of California - San Francisco) Using advanced technology, scientists at Chan Zuckerberg (CZ) Biohub, Mayo Clinic and University of California, San Francisco (UCSF), have discovered an autoimmune disease that appears to affect men with testicular cancer.Called 'testicular cancer-associated paraneoplastic encephalitis,' the disease causes severe neurological symptoms in men. They progressively lose control of their limbs, eye movements, and speech. The disease begins with a testicular tumor, which may cause the immune system to attack the brain.

In this study, we reported the case of a 74-year-old Japanese woman who developed PLE after partial remission of small cell lung cancer (SCLC) by first-line systemic chemotherapy. Brain magnetic resonance imaging showed no metastatic tumor or cerebrovascular disease. Anti-glutamic acid decarboxylase (GAD) and anti-amphiphysin antibodies were detected in her serum. She was diagnosed as having PLE related to the recurrence of SCLC and received high-dose glucocorticoid, and sequentially systemic chemotherapy with amrubicin. Unfortunately, these treatments did not improve her disease progression and she died 4 months later. Al...

ConclusionsTo the best of our knowledge, renal malignancy presenting as syndrome of inappropriate antidiuretic hormone secretion and Leser –Trélat concurrently is rare. The causes of hyponatremia in the elderly, approach to investigation, and value as a poor prognostic marker in malignancy are highlighted. We also discuss Leser–Trélat syndrome, its pathophysiology, and its possible implications on clinical practice.

Ma2 antibody-associated encephalitis is an inflammatory brain disease that associates with a systemic tumor in more than 90% of patients, most commonly a testicular germ-cell tumor, lung cancer, or breast cancer. The Ma2 antibody-mediated autoimmune encephalitis presents mostly as limbic, mesodiencephalic, or brain stem encephalitis. Cranial MRI often detects T2-hyperintense lesions that may progress to atrophy. However, other areas of the CNS, such as the brainstem, the thalamus, the hypothalamus, the cerebellum, or the basal ganglia may also be affected. Approximately one-third of patients with Ma2 antibody-associated en...

Discussion: While the incidence of melanoma of unknown primary is between 2.6 and 3.2%, with a median overall survival ranging between 24 and 127 months, when melanoma patients develop OMS their survival is markedly decreased. Although only 5 cases of paraneoplastic OMS secondary to melanoma have been reported in the literature, all had a poor prognosis, dying within 8 months of OMS onset.Case Rep Neurol 2019;11:66 –79
