  Paraneoplastic syndromes of the nervous system are a heterogeneous group of disorders that accompany benign or malignant tumors but are not directly related to mass effects or invasion. […] Paraneoplastic syndromes can affect the central nervous system, peripheral nervous system, neuromuscular junction, and muscles. […] The document discusses the pathogenesis of paraneoplastic syndromes and antibodies associated with different syndromes. […] Immunological factors are believed to be responsible for paraneoplastic syndromes. […] The immune system identifies certain antigens expressed by tumors as foreign and mounts an immune attack against them. […] Antibodies that occur in paraneoplastic disorders have been divided into two categories depending on the location of the antigen. […] Well-characterized paraneoplastic antibodies are almost always detectable in serum.

• #7 Paraneoplastic Syndromes: Practice Essentials, Pathophysiology, Etiology

  https://emedicine.medscape.com/article/280744-overview

  The pathogenesis of neuromuscular paraneoplastic disorders is unknown, but they probably are multifactorial, correlated with a virus becoming virulent, autoantibody formation, or production of substances that alter nervous functions. […] Patients with cerebellar paraneoplastic disorders usually have degenerative loss of the molecular, granular, and Purkinje layers of the cerebellar cortex. […] Individuals with paraneoplastic encephalitis commonly have lymphocytic infiltration of the medial sections of the temporal lobes, with a loss of neurons. […] The reported frequency of paraneoplastic syndromes ranges from 10-15% to 2-20% of malignancies, However, these could be underestimates. […] Death may result from the underlying cancer or from an irreversible system impairment, usually acute heart failure or kidney failure.

  Paraneoplastic neurologic syndromes (PNS) may be the presenting symptom of cancer. […] Neurologic complications occur in approximately 20 percent of patients treated for cancer. […] The focus of this chapter is PNS, a constellation of rare but well-described syndromes associated with cancer. […] The neurologic symptoms of paraneoplastic syndromes typically present before the tumor is diagnosed. […] Patients often survive the tumor but with persistent neurologic effects. […] The hypothesis is that patients develop neurologic symptoms because the tumor expresses onconeural antigens that cause a cellular and/or humoral response; this then cross-reacts with specific antigens in varied regions of the nervous system. […] PNS may cause injury anywhere along the neuraxis. […] The PNS are divided into two major categories: classical syndromes that strongly suggest an associated malignancy, and nonclassical ones that are only occasionally associated with malignancy.

  Paraneoplastic neurological syndromes (PNS) include any symptomatic and non-metastatic neurological manifestations associated with a neoplasm. […] Clinicians should have a high index of suspicion with acute/subacute encephalopathies to achieve a prompt diagnosis and treatment. […] Standardized diagnostic criteria and disease biomarkers are fundamental to quickly recognize PNS to allow prompt treatment initiation, thus improving the long-term outcome of these conditions. […] The traditional classification of PNS and related antibodies has been recently revised by a panel of experts which developed a new set of diagnostic criteria with the aim of improving the clinical management of these conditions. […] The panel also identified recommendations for PNS triggered by immune-checkpoint inhibitors (ICIs), a treatment class currently used to treat cancers.

  Paraneoplastic syndromes are a rare group of diseases that sometimes develop when there is cancer in the body. […] Depending on what part of the nervous system is impacted by PNS, it may cause problems with movement, coordination, memory, cognition, sensory perception, and sleep. […] Damage to the nervous system can sometimes be healed or reversed once the cancer is treated and the immune system is functioning more appropriately. […] Regardless, treatment interventions at any time may prevent further damage and allow for a better quality of life. […] Symptoms of PNS vary depending on the system in the body that is impacted. […] Identifying symptoms of PNS can help your healthcare provider detect cancer in its earliest stages when it is more treatable. […] Paraneoplastic syndrome impacts the nervous system, so your doctor will assess your brain functioning and look for any issues with movement or coordination.

• #35 Paraneoplastic neurological syndrome with positive anti-Hu and anti-Yo antibodies: A case report

  https://www.wjgnet.com/2307-8960/full/v10/i13/4190.htm

  Current research suggests that the main etiology of PNS is immune-related, with the presence of tumor-associated antigens in neurons, which causes a cross-immune reaction between antibodies produced by the body’s immune response, consequently neural tissue-damaging symptoms appear. The clinical symptoms include mainly subacute cerebellar ataxia, abnormal mental behavior, and seizures. Anti-Hu and anti-Yo antibodies are the most common markers, with the former being seen in SCLC and the latter in patients with gynecological tumors or breast cancer. […] Anti-Hu antibody is associated with SCLC. Anti-Yo antibody positivity is mostly observed in gynecological and breast tumors. As the neurological paraneoplastic syndrome often precedes the appearance of solid tumors, patients with a history of tumors might have recurrent tumors, and whole-body imaging and pathology should be completed to clarify whether the patient has recurrent tumors or new and different tumors. Therefore, clinicians should consider the possibility of two malignancies when these two paraneoplastic antibodies are both positive. Early diagnosis and treatment of PNS and the tumors can significantly improve the prognosis of patients.

  Paraneoplastic neurological syndromes (PNS) are diseases of the central and peripheral nervous system that occur in direct association with tumours. […] Approx. 15% of patients with malignant diseases, especially lung tumours, have PNS. […] Neuronal antibodies have been established as useful biomarkers and their detection is of paramount importance in the diagnosis of PNS. […] For a reliable diagnosis, the guidelines recommend that autoantibodies in PNS should always be determined using two independent methods. […] With the exception of opsoclonus-myoclonus syndrome, the diagnosis of definite PNS requires the presence of high- or intermediate-risk antibodies.

  https://clinicalpub.com/paraneoplastic-disorders-of-the-nervous-system/

  The specificity of paraneoplastic anti-neuronal antibodies for PNSs or some types of cancer makes them useful diagnostic tools. In approximately 65% of patients with PNS, the neurological symptoms precede the tumor diagnosis. Therefore in the right clinical context the detection of a paraneoplastic antibody in the serum or CSF helps to diagnose the PNS and focus the search for the neoplasm. […] The diagnosis of PNS can be made to different degrees of certainty by taking into consideration the type of syndrome, detection of a tumor, and presence or absence of paraneoplastic antibodies. The diagnosis of PNS is relatively straightforward for patients who develop symptoms of a well-defined syndrome that is typically associated with cancer. […] The diagnosis of PNS is more difficult in patients who develop less characteristic symptoms, especially if no antibodies are found in the serum or CSF. Most PNSs have an acute or subacute onset compared with noninflammatory neurodegenerative disorders that are chronically progressive.

Prompt and effective treatment of the underlying malignancy may arrest progression of autonomic dysfunction, but in many cases, no improvement occurs. Survival is dependent on underlying cancer, patient age, and extent of nervous system involvement. The median survival of all patients with paraneoplastic syndromes has been estimated to be 1 to 3 years. […] Sudden death, often due to cardiac causes, can occur. Intestinal pseudo-obstruction and urinary tract infections from incomplete bladder emptying are possible. Overheating due to reduced sweat function can occur in hot temperatures or with physical exertion.

  The specificity of paraneoplastic anti-neuronal antibodies for PNSs or some types of cancer makes them useful diagnostic tools. In approximately 65% of patients with PNS, the neurological symptoms precede the tumor diagnosis. Therefore in the right clinical context the detection of a paraneoplastic antibody in the serum or CSF helps to diagnose the PNS and focus the search for the neoplasm. […] The diagnosis of PNS can be made to different degrees of certainty by taking into consideration the type of syndrome, detection of a tumor, and presence or absence of paraneoplastic antibodies. The diagnosis of PNS is relatively straightforward for patients who develop symptoms of a well-defined syndrome that is typically associated with cancer. […] The diagnosis of PNS is more difficult in patients who develop less characteristic symptoms, especially if no antibodies are found in the serum or CSF. Most PNSs have an acute or subacute onset compared with noninflammatory neurodegenerative disorders that are chronically progressive.

  Paraneoplastic neurological syndromes (PNS) are a group of neurological disorders resulting from an immune response triggered by an underlying tumor that affects the central and/or peripheral nervous systems, directed originally against the tumor itself. […] PNS presentation often precedes cancer diagnosis, with the large majority of tumors being diagnosed within two years of onset of the neurologic disorder. […] General approaches to treatment include removal of the antigen source by treatment of the underlying tumors immunosuppression and supportive therapy. […] Rapid detection and immediate treatment of the underlying tumor appears to offer the best chance of stabilizing the patient and preventing further neurological deterioration. […] Coordination between the physiatrist, therapist, oncologist, and neurologist are paramount. […] Frequent education of the patient and family helps patients make informed decisions regarding their disease course. […] PNS is difficult to diagnose but early diagnosis and initiation of treatment is critical to prevent permanent neurological deficits.
