Paraneoplastic Cerebellar Degeneration Associated with Breast Cancer: A Case Report and a Narrative Review. Brain Sci 2024; 14:176. [PMID: 38391750 PMCID: PMC10887192 DOI: 10.3390/brainsci14020176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 01/23/2024] [Accepted: 02/07/2024] [Indexed: 02/24/2024] Open
Abstract
Paraneoplastic neurological syndromes (PNSs) are an uncommon complication of cancer, affecting nearby 1/10,000 subjects with a tumour. PNSs can involve all the central and peripheral nervous systems, the muscular system, and the neuromuscular junction, causing extremely variable symptomatology. The diagnosis of the paraneoplastic disease usually precedes the clinical manifestations of cancer, making an immediate recognition of the pathology crucial to obtain a better prognosis. PNSs are autoimmune diseases caused by the expression of common antigens by the tumour and the nervous system. Specific antibodies can help clinicians diagnose them, but unfortunately, they are not always detectable. Immunosuppressive therapy and the treatment of cancer are the cornerstones of therapy for PNSs. This paper reports a case of PNSs associated with breast tumours and focuses on the most common paraneoplastic neurological syndromes. We report a case of a young female with a clinical syndrome of the occurrence of rigidity in the right lower limb with postural instability with walking supported and diplopia, with a final diagnosis of paraneoplastic cerebellar degeneration and seronegative rigid human syndrome associated with infiltrating ductal carcinoma of the breast.

Abstract
Diseases of the brachial and lumbosacral plexus are uncommon and complex. The diagnosis of plexopathies is often challenging for the clinician, both in terms of localizing a patient's symptoms to the plexus as well as determining the etiology. The non-specific clinical features and similar presentations to other root, nerve, and non-neurologic disorders emphasize the importance of a high clinical index of suspicion for a plexopathy and comprehensive clinical evaluation. Various diagnostic tests, including electrodiagnostic (EDX) studies, neuroimaging (including ultrasound, MRI, or PET), serologic studies, and genetic testing, may be used to confirm a plexopathy and assist in identifying the underlying etiology. EDX testing plays an important role in confirming a plexopathy defining the localization, pathophysiology, chronicity, severity, and prognosis. Given the complexity of the plexus anatomy, multiple common and uncommon NCS and an extensive needle examination is often required, and a comprehensive, individualized approach to each patient is necessary. Treatment of plexopathies often focuses on symptomatic management although, depending on the etiology, specific targeted treatments may improve outcome. This article reviews the clinical features, EDX approaches, and evaluation and treatment of brachial and lumbosacral plexopathies.

Abstract
Cancer and its treatment exert a heavy psychological and physical toll. Of the myriad symptoms which result, pain is common, encountered in between 30% and 60% of cancer survivors. Pain in cancer survivors is a major and growing problem, impeding the recovery and rehabilitation of patients who have beaten cancer and negatively impacting on cancer patients' quality of life, work prospects and mental health. Persistent pain in cancer survivors remains challenging to treat successfully. Pain can arise both due to the underlying disease and the various treatments the patient has been subjected to. Chemotherapy causes painful chemotherapy-induced peripheral neuropathy (CIPN), radiotherapy can produce late effect radiation toxicity and surgery may lead to the development of persistent post-surgical pain syndromes. This review explores a selection of the common causes of persistent pain in cancer survivors, detailing our current understanding of the pathophysiology and outlining both the clinical manifestations of individual pain states and the treatment options available.

Abstract
Recent progress in serological screening of paraneoplastic antibodies and in diagnostic imaging techniques to detect malignancies has enabled a broadening of the concept of paraneoplastic neurological syndromes by integrating nonclassic clinical features. The peripheral nervous system is frequently involved in patients with paraneoplastic syndrome and may be seen alone or in combination with involvement of other areas of the nervous system. Destruction of dorsal root ganglion cells due to lymphocytic infiltration, especially with CD8-positive cytotoxic T cells, has been postulated to mediate the classic syndrome of subacute sensory neuronopathy. However, the motor and autonomic nervous systems are frequently affected. Indeed, patients can develop clinical features compatible with Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, or brachial plexopathy. Other forms of paraneoplastic neuropathy are vasculitic neuropathy, autoimmune autonomic ganglionopathy, and chronic intestinal pseudo-obstruction. Various onconeural antibodies, including anti-Hu, anti-CV2/CRMP-5, and anti-ganglionic acetylcholine receptor antibodies, are associated with neuropathy. Somatic neuropathy is the most common manifestation in patients with anti-Hu and anti-CV2/CRMP-5 antibodies, while anti-ganglionic acetylcholine receptor antibody is associated with autonomic neuropathies. A whole-body fluorodeoxyglucose positron emission tomography scan may be useful to detect malignancy in patients with unremarkable conventional radiological findings. Recognition and diagnosis of paraneoplastic neuropathy is important, as neuropathic symptoms usually precede the identification of the primary tumor, and treatment at an earlier stage provides better chances of good outcomes.

Abstract
Disorders of the peripheral nerve system (PNS) are heterogeneous and may involve motor fibers, sensory fibers, small myelinated and unmyelinated fibers and autonomic nerve fibers, with variable anatomical distribution (single nerves, several different nerves, symmetrical affection of all nerves, plexus, or root lesions). Furthermore pathological processes may result in either demyelination, axonal degeneration or both. In order to reach an exact diagnosis of any neuropathy electrophysiological studies are crucial to obtain information about these variables. Conventional electrophysiological methods including nerve conduction studies and electromyography used in the study of patients suspected of having a neuropathy and the significance of the findings are discussed in detail and more novel and experimental methods are mentioned. Diagnostic considerations are based on a flow chart classifying neuropathies into eight categories based on mode of onset, distribution, and electrophysiological findings, and the electrophysiological characteristics in each type of neuropathy are discussed.

Acta Neurochir (Wien) 2009; 151:1089-98.

Abstract
BACKGROUND Tumours of the brachial plexus region are rare and most publications are case reports or studies with a small series of patients. The aim of this study is to present our experience in managing these lesions. METHODS We review 18 patients with tumours in the brachial plexus region submitted to surgical treatment in a 6 year period, including their clinical presentation, neuro-imaging data, surgical findings and outcome. FINDINGS The tumours comprised a heterogeneous group of lesions, including schwannomas, neurofibromas, malignant peripheral nerve sheath tumour (MPNST), sarcomas, metastases, desmoids and an aneurysmal bone cyst. The most common presentation was an expanding lump (83.33%). Eleven tumours were benign and 7 were malignant. Neurofibromatosis was present in only 2 patients (11.11%). Gross total resection was achieved in 14 patients and sub-total resection in the others. Only 3 patients presented with new post-operative motor deficits. The incidence of complications was low (16.5 %). CONCLUSIONS The majority of tumours were benign and most of them could be excised with a low incidence of additional deficits. Some of the malignant tumours could be controlled by surgery plus adjuvant therapy, but this category is still associated with high morbidity and mortality rates.

Abstract
Multilevel cervical spondylosis is a common disorder encountered by most actively practicing spine surgeons. Patients can present with a combination of complaints, including mechanical neck pain, radiculopathy, and myelopathy. A comprehensive evaluation is required for appropriate diagnosis and treatment. Accurate interpretation of imaging techniques, including plain x-rays, CT, and MRI, is necessary to formulate the optimal surgical strategy. Key points to address during construction of the operative plan include the direction of approach, the extent of the decompression, and the type of stabilization construct when necessary. This article outlines various techniques to facilitate operative planning, optimize the surgical objective, and minimize potential complications.

Abstract
PURPOSE OF REVIEW To describe the paraneoplastic disorders of the motor and sensory nerves and neurons, and their immunologic associations. RECENT FINDINGS Recently proposed diagnostic criteria for paraneoplastic disorders may assist in determining the likelihood a given neuropathy or neuronopathy is related to an underlying malignancy. Of this group of disorders, paraneoplastic sensory neuronopathies are the most frequent; many of these patients have anti-Hu antibodies and small-cell lung cancer. There is often motor, autonomic, or central nervous system involvement, and electrophysiological studies may demonstrate not only sensory changes, but also motor abnormalities. While cancer has been found more frequently than expected in patients with Guillain-Barré syndrome, this association is extremely rare. A limited number of reports have described chronic inflammatory demyelinating polyradiculoneuropathy, multifocal motor neuropathy with conduction block, vasculitic neuropathies, and motor neuron disease as paraneoplastic disorders. Anti-CV2 antibodies are frequently associated with a paraneoplastic sensorimotor axonal neuropathy and small-cell lung cancer. Peripheral nerve hyperexcitability may occur with or without a cancer association, and in both instances patients often have antibodies to voltage-gated potassium channels; thymoma and small-cell lung cancer are the most common underlying tumors. Plasma cell proliferative disorders are frequently associated with neuropathies, particularly demyelinating ones. SUMMARY There is increasing recognition of an extensive variety of paraneoplastic disorders of the peripheral nerves. In many of these disorders onconeuronal antibodies are absent. Whole body fluorodeoxyglucose positron emission tomography scanning helps uncover the associated tumor, and recently proposed criteria may assist in the diagnosis. In many instances, prompt treatment of the tumor and immunotherapy result in symptom stabilization or neurologic improvement.

Abstract
Peripheral nerve involvement in the course of neoplastic disease represents a clinically significant complication, with clinical uncertainties raising questions as to its pathophysiology. The aim of this study was the analysis of ATPase activities, lipid peroxidation and sulfhydryl groups in the sciatic nerve of tumor-bearing rats. We investigated also morphometric features of the sciatic nerve of experimental animals. An increase was noted in Na+/K+-ATPase and Mg+2-ATPase activities and elevation of conjugated diene and malonyldialdehyde contents, associated with a decrease in sulfhydryl groups in Morris-hepatoma-bearing rats. The morphometric evaluation revealed myelin sheath thickening, associated with an increase in axon cross-section area and degenerative changes in dorsal horns. In this study, the moderate lipid peroxidation in experimental neoplastic disease was demonstrated to lead to depletion of sulfhydryl groups in the degenerating rat sciatic nerve which was associated with stimulation of ATPase activities.

Abstract
Cancer metastasis can affect any part of the nervous system. When the peripheral nervous system is involved, the usual targets are cranial nerves, nerve roots and plexi. However, peripheral nerves and muscles can also be affected by compression or infiltration of neoplastic cells. This review focuses in the diagnosis and treatment of metastatic complications of cancer involving plexi, peripheral nerves and muscles.
