Frequently paraneoplastic syndromes can precede the diagnosis of the neoplasm or present with limited stage disease. LEMS is the most common neurological paraneoplastic syndrome in small cell lung cancer (SCLC). Register for free and gain unlimited access to: - Clinical News, with personalized daily picks for you The most common cancers with which paraneoplastic syndrome occurs are breast cancer, lung cancer, kidney cancer, ovarian cancer, stomach cancer, pancreatic cancer, lymphomas, and leukaemia. Ectopic ACTH secretion caused new-onset diabetes mellitus and likely contributed to hypokalemia, metabolic alkalosis, thoracic compression fracture, hypertension, and emotional liability. Muscle biopsy will reveal perivascular or interfascicular septal inflammation and perifascicular atrophy. Subclinical presentation of ECS in lung cancer (SCLC) has been reported and is defined as elevation of cortisol that does not demonstrate normal suppression after administration of exogenous steroids in the absence of overt clinical signs and symptoms of Cushing syndrome. Trousseau syndrome and the unknown cancer: use of positron emission tomographic imaging in a patient with a paraneoplastic syndrome. LEMS is a rare autoimmune disorder of the neuromuscular junction and may precede the diagnosis of lung cancer. During low-rate RNS, the decrease in CMAP amplitude can be seen in LEMS and MG (myasthenia gravis). Gallium nitrate inhibits osteoclast action, blocking bone resorption. Ketoconazole and metyrapone are typically used as first line therapies, and may be combined to improve the control of cortisol production. Lung Cancer and Paraneoplastic Syndromes AmitaVasoya D.O., FACOI, FCCP, FAASM Christiana Care Pulmonary Associates Clinical Assistant Professor of Medicine Sidney Kimmel Medical College of Thomas Jefferson University Rowan University School of Osteopathic Medicine ACOI Board Review 2018 Cushing’s syndrome due to other causes may mimic ECS and include endogenous Cushing syndrome due to adrenal adenoma, adrenal carcinoma, nodular adrenal hyperplasia, or due to use of exogenous glucocorticoids. Rheumatologic system: Numerous autoimmune disorders may include polymyositis-dermatomyositis, cutaneous vasculitis, hypertrophic pulmonary osteoarthropathy, Raynaud’s phenomenon, overlap syndrome, systemic lupus erythematosus, polymyalgia rheumatica, and Still’s disease. Search for pulmonary malignancy with chest radiograph or computed tomography if no other primary cause is evident is recommended as SIADH could be the presenting symptom for lung cancer, particularly in smokers. Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to a neoplasm or ectopic production of a hormone or cytokine. Neurological manifestations of cancer are common, disabling, and often multifactorial (table 1). Only the Lambert-Eaton myasthenic syndrome is relatively frequent, occurring in about 1% of patients with small cell lung cancer. Helpful criteria to diagnose PCD include: development of severe pancerebellar syndrome in < 12 weeks, the absence of accelerated cerebellar atrophy more than that associated with normal and difficulties with usual daily activities. Other disorders include central nervous system involvement (Encephalomyelitis, Brainstem encephalitis, stiff-person syndrome, extrapyramidal disease/chorea, necrotizing myelopathy, and myelitis), paraneoplastic visual syndromes (cancer-associated retinopathy and paraneoplastic optic neuropathy), motor neuron syndromes (subacute motor neuropathy; and other motor neuron syndromes), peripheral nervous system (acute and chronic polyradiculitis, acute sensorimotor neuropathy, chronic sensorimotor neuropathy, brachial neuritis, acute pan-dysautonomia, autonomic dysfunction, chronic gastrointestinal pseudo-obstruction, paraneoplastic peripheral nerve vasculitis, and Adie’s syndrome with paraneoplastic sensorimotor neuropathy and cerebellar ataxia), neuromuscular junction and muscle (Myasthenia gravis), polymyositis/dermatomyositis, acute necrotizing myopathy, cachectic myopathy, neuromyotonia, and dementia. Pathology. ANNA-1/Anti-Hu antibodies associated with small cell lung cancer. Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to a neoplasm or ectopic production of a hormone or cytokine. The magnitude of cortisol production, progression of the underlying cancer, and patient vulnerability determine the severity of symptoms. Absence of direct complications of cancer such as: Metastasis, infection, metabolic complication, nutritional deficits, cerebrovascular disorder or side effects of treatment. Paraneoplastic syndromes occur in as many as 10 to 15 percent of cancer patients. Ectopic Cushing syndrome due to ACTH or CRH secretion not related to lung cancer may be due to bronchial carcinoid tumors, due to thymic or pancreatic neuroendocrine tumors, medullary thyroid cancer, pheochromocytoma, prostatic cancer. Sixty percent of all PLE cases are paraneoplastic. The antibodies associated with immune-mediated limbic encephalitis and lung cancer include AMPAR (Autoimmune or paraneoplastic, SCLC), GABABR (Autoimmune or paraneoplastic, SCLC), GAD-65, ANNA1 (Hu, paraneoplastic, SCLC), ANNA 3 (paraneoplastic, SCLC), Amphiphysin (paraneoplastic, SCLC and breast), and CRMP-5 (paraneoplastic, SCLC or thymoma). In cases of Lambert-Eaton Myasthenic syndrome, clinicians should consider monitoring for signs of respiratory involvement, although such signs are rare. Manifestations of Paraneoplastic Syndromes: Are you sure your patient has a paraneoplastic syndrome associated with lung cancer? Saunders. A Case of Anti-CRMP5 Paraneoplastic Neurological Syndrome Induced by Atezolizumab for Small Cell Lung Cancer. Early stage of SCLC is difficult to detect by conventional radiography or bronchoscopy. 1, Syniachenko O.V. PLE is most commonly associated with SCLC in almost 50% of the cases. More conservative correction may be necessary in patients with alcoholism, severe malnutrition or advanced liver disease that may be more susceptible to ODS. Paraneoplastic limbic encephalitis (PLE) is indistinguishable from PLE due to other causes but is usually a part of multifocal encephalomyelitis, and rarely a solitary syndrome. Several other onconeural antigens have been identified by examination of serum samples from patients with paraneoplastic syndromes. LEMS is associated with negative inspiratory force less than 25 H2O and FVC less than 15-20 ml/kg. Somatostatin analogs at standard agent-specific doses. Registration is free. The symptoms can involve virtually any body system an… Paraneoplastic syndromes are defined as symptoms and signs distant to the primary tumor site and unrelated to local effects or metastasis. Limbic encephalitis (LE) affects the medial temporal lobe of the brain and has numerous causes including infection, autoimmune diseases or cancer. Neurologic symptoms, source of cancer and the types of antibodies are highly correlated. Cancer Ther 2008;6:687-98. Has anyone had, have, or heard of paraneoplastic syndrome with lung cancer? CSF sampling reveals elevated protein levels, lymphocytic pleocytosis, elevated IgG index, and oligoclonal bands. Mannitol and glycine infusion (typically in the setting of neurosurgical and urologic disease respectively), as well as hyperglycemia may cause hyponatremia not due to SIADH. These may involve the central nervous system (limbic encephalitis, cerebellar degeneration, opsoclonus-myoclonus), the neuromuscular junction (Lambert-Eaton, myasthenic syndrome) or peripheral nervous system (subacute sensory neuropathy). Cutaneous necrosis, heliotrope erythema, dysphagia, dyspnea, muscle weakness, arthralgia, and positive anti-155/140 antibodies are considered as risk factors for cancer. Midline cerebellar dysfunction (inability to stand without assistance), speech (progressive dysarthria), and nystagmus (horizontal or vertical, opsoclonus and ocular dysmetria) are also symptoms. Potential risks include rebound hypercalcemia after twenty-four hours, vomiting, cramps, and flushing. More than 50% of patients with LE due to SCLC may demonstrate complete or partial improvement with treatment when GABA-B antibodies are present. Azathioprine may be used as a glucocorticoid-sparing agent at an initial dose of 50 mg/day. 12. It therefore requires constant hemodynamic monitoring and ICU admission. Serum CK, AST, ALT, LDH and aldolase levels are elevated. Already have an account? Anti-neuronal antibody may be helpful in identifying the source of cancer. Though some results are favorable the experience with these agents is still limited and they are usually not recommended as a first line of treatment or monotherapy. Antineuronal nuclear antibodies (ANNA-1/Hu or ANNA-2/Ri) support the diagnosis of SCLC but are present in less than half of patients. Paraneoplastic syndromes associated with small cell lung cancer a We believe that two paraneoplastic syndromes derived from SCLC affected this patient (ACTH and calcitonin). Paraneoplastic neurological disorders (PND) usually develop before an underlying tumor is recognized, often leading to tumor diagnosis. Ectopic Cushing syndrome is typically caused by production of ACTH by non-pituitary tissue leading to hypercortisolism. Chest-computed tomography is useful to evaluate for small-cell lung cancer, especially in the presence of anti-Hu antibodies. On physical examination, proximal lower and upper extremity weakness, augmentation of strength during the first seconds of a maximum effort, and absent deep tendon reflexes may be found. Goldman's Cecil Medicine: Expert Consult Premium Edition - Enhanced Online Features and Print, Single Volume. However, rare reports of Cushing syndrome due to ectopic production CRH (corticotropic releasing hormone) and POMC (pro-opiomelanocortin) also exist. MRI of brain and spinal cord are useful for excluding other neurologic disorders. The incidence of clinical SIADH among patients with lung cancer is 7-16% depending on the definitions used. Paraneoplastic Syndromes. ISBN:0199772738. Mayo Clin. Beware: there are other diseases that can mimic a paraneoplastic syndrome associated with lung cancer: How frequent are paraneoplastic syndromes associated with lung cancer? Clinical features also include depression, personality change or irritability; partial complex or motor seizures involving the face and extremities; gustatory and olfactory hallucinations; hyperphagia, drowsiness, hyperthermia, and pituitary hormonal deficits; and asymmetric loss of sensation in the extremities (hands more than legs). Plasma exchange therapy is alternative option for LEMS and other autoimmune neurological disorders. When found with lung cancer, they most commonly occur with squamous cell and small cell lung cancer. Direct tumoral osteolysis leading to hypercalcemia mediated by local factors including IL-1, IL-6, IL-11, PGE, TGF-α, TGF-β, and TNF-β occurs in 20% of all cancers (mainly breast, multiple myeloma and lymphoma). Type of paraneoplastic syndrome: Subtype: Associated Cancers: Endocrine: Hypercalcemia; Breast cancer and lung cancer (typically squamous cell) due to the production of PTHrP (Parathyroid hormone-related protein)multiple myeloma, renal cell carcinoma, ovarian cancer, endometrial cancer, and lymphoma; SIADH Mycophenolate mofetil 2 grams/day may be an effective agent but is associated with bone marrow suppression, infection and gastrointestinal side effects. Your use of this website constitutes acceptance of Haymarket Media’s Privacy Policy and Terms & Conditions. The optimal dose of denosumab during renal insufficiency is not clear. This is best visualized on T1 weighted imaging. Paraneoplastic neurological syndromes (PNS) can be defined as remote effects of cancer that are not caused by the tumor and its metastasis, or by infection, ischemia or metabolic disruptions. The majority of patients are asymptomatic and symptoms generally develop when serum sodium falls below 125 mmol/L. In addition to treatment of the underlying cancer, symptomatic mild hyponatremia can be treated with fluid restriction. Oral Prednisone (0.5-1.5 mg per kg or 80-100 mg/day) is the initial treatment, until serum creatine kinase levels normalize. Cancer Ther 2008;6:687-98. Paraneoplastic syndromes 1. - Full-Length Features Once on a stable dose, CBC and LFTs should be rechecked every 3 months. Paraneoplastic syndromes occur in 10-20% of patients. They are mediated by endocrine and immune mechanisms. She was non-verbal and combative, requiring involuntary admission and declaration of incompetence to make healthcare treatment decisions. The incidence of LEMS is 3% in SCLC patients. LEMS responds to treatment of lung cancer, and the prognosis is related to that for the underlying malignancy. Cutaneous system: Skin involvement may present with acanthosis nigricans, dermatomyositis, leukocytoclastic vasculitis, pseudoscleroderma, erythema multiform, Sweet syndrome, pruritus and urticaria, tylosis, erythema gyratum repens, Immunoglobulin A pemphigus, herpetiformis pemphigus, anti-epiligrin cicatricial pemphigoid, and acantholytic bullous dermatosis. The usual culprit is small cell lung cancer (SCLC). RELATED: International Cooperation Vital for Preventing Lung Cancer. EEGs are not usually useful for the diagnosis, as they may show non-specific findings, such as slowing or normal. Paraneoplastic syndrome in lung cancer. Paraneoplastic syndromes that present in association with lung cancer can also be specific to the histology of lung cancer. We reported a case of a 56-year-old man with squamous cell carcinoma of the lung confined to a single hilar lymph node presenting with biopsy-proven polymyositis of 3 months in … Physical examination shows signs of cerebellar dysfunction, loss of coordination of unilateral onset, and progression to equal involvement of both sides and severe ataxia involving arms and legs. However, given seronegativity of the most patients, indicates the cell-mediated immune mechanism as the major responsible mechanism for the pathogenesis of opsoclonus. PNS are rare, affecting less than 1/10,000 patients with cancer. Plain radiographs of sites of bony pain may reveal the presence of metastasis. Paraneoplastic syndromes of the nervous system … Batsis JA, Morgenthaler TI. Side effects include gastrointestinal symptoms with oral dosing, suppression of adrenal function, immunosuppression, osteoporosis, glucose intolerance, and weight gain. An association between polymyositis and lung cancer has been debated. Though MRI of the pituitary gland, with high level of cortisol makes Cushing disease as a source of cortisol unlikely, since ACTH secreting pituitary adenomas are often small, inferior petrosal sinus sampling is typically necessary to definitively distinguish between ectopic and pituitary Cushing syndrome. Abdomen-computed tomography and mammography are useful to evaluate for breast or ovarian cancer, particularly if anti-Yo antibodies are present in CSF. Paraneoplastic syndromes Sir Charles Gairdner Hospital Vera Ruchti 10/7/2014 2. All SSAs may cause cholestasis and biliary symptoms, GI side effects, and hyperglycemia. It is contraindicated in renal failure. POMS may be associated with several onconeural autoantibodies which may be compatible with involvement of humoral immune mechanism. Plicamycin (25 mcg/kg for 3-8 doses) blocks RNA synthesis in osteoclasts and is effective in lowering serum calcium, but it is toxic to the bone marrow, liver, and kidney. Immunotherapy, such as corticosteroids or IVIG does demonstrate some efficacy in patients with idiopathic opsoclonus, but only appears to be helpful in POMS when the underlying tumor has been controlled. Frequently, circulating tumor markers (TMs) are considered a valuable tool for cancer diagnosis in patients with paraneoplastic neurologic syndromes … Paraneoplastic syndromes can affect multiple systems and have a diverse presentation. This material may not be published, broadcast, rewritten or redistributed in any form without prior authorization. Those with small-cell lung carcinoma are at greatest risk, although SIADH can also be seen in carcinoid tumors. In the case of lung cancer, they are mostly found either in squamous lung cells or small cell lung cancer. When the body mounts an immune response to the tumour cells, the antibodies and immune cells produced then also attack the nervous system, causing progressive nerve damage. Today my dad’s radiation oncologist, who spoke with the neuro oncologist about my dad’s abnormal brain MRI, and they feel he may have a paraneoplastic syndrome from the lung cancer that is mimicking Multiple sclerosis in his body, though he said he has never seen it mimick MS before. Oxford University Press. Endocrine syndromes, particularly the syndrome of inappropriate ADH secretion (SIADH) and humoral hypercalcemia of malignancy (HHM), are the most common paraneoplastic syndromes seen in lung cancer … Electromyography will reveal increased spontaneous activity with fibrillations, complex repetitive discharges, low-amplitude, short duration polyphasic motor unit action potential, and positive sharp waves in the presence of dermatomyositis. The onset of PCD is often subacute with progression over weeks to months and may precede tumor diagnosis. Valproic acid may add an adjunctive benefit in addition to standard chemotherapy in small cell lung cancer patients. We hope you’re enjoying the latest clinical news, full-length features, case studies, and more. 1 Those involving the visual system are considerably less common, and can be easily overlooked given their subtle warning signs. SCLC is the most common cancer histology associated with paraneoplastic syndromes. Approximately 25% of patients with small lung cancer (SCLC) develop hyponatremia and 60% of these cases is due to SIADH, other causes included hypervolemia (congestive heart failure), using diuretic (especially thiazide), or other medications (antidepressants and chemotherapeutic agents). Those with small-cell lung cancer are at greatest risk, although the condition can also be seen in other malignancies (breast, uterus, bladder, thyroid, and pancreatic cancers). The most sensitive diagnostic test is positive repetitive nerve stimulation (RNS), which should be done on at least two distal muscles. Direct inhibitors of steroidogenesis include ketoconazole, metyrapone, and mitotane. If you decide the patient has a paraneoplastic syndrome associated with lung cancer, how should the patient be managed? The most well-recognized paraneoplastic neurologic syndrome, both clinically and on imaging, is limbic encephalitis. Severe hypothyroidism and primary adrenal insufficiency may also cause symptoms, signs and laboratory changes indistinguishable from those associated with SIADH and must therefore be excluded prior to assigning diagnosis. An MRI can be normal in most patients, or it may show areas of increased T2 signal. Male gender, age > 60, squamous cell histology, lower performance status, higher staging, leukocytosis, bone metastasis, renal failure, severity of hypercalcemia, elevated alkaline phosphatase, brain metastasis, multiple distant metastasis (≥2) correlate with poorer prognosis in these patients. Dumansky Yu.V. Those at greatest risk of hypercalcemia are those with non-small-cell lung cancer, particularly the squamous cell variety. The usual culprit is small cell lung cancer (SCLC). Lung Cancer and Paraneoplastic Syndromes AmitaVasoya D.O., FACOI, FCCP, FAASM Christiana Care Pulmonary Associates Clinical Assistant Professor of Medicine Sidney Kimmel Medical College of … Chest-computed tomography scan will reveal mediastinal mass, pulmonary nodule or mass, endobronchial lesion or segmental/lobar collapse. Paraneoplastic syndrome is mediated through: Cross reacting antibodies Production of physiologically active factors Interference with … - Conference Coverage We present a case of PLE as the initial manifestation of SCLC, … The disease improves with treatment of the underlying malignancy, and the cause of death is usually the malignancy, not the dermatomyositis. here. Computed tomography (CT), 18F-fluorodeoxyglucose-positron emission tomography (PET) or PET/CT are more sensitive to identify occult SCLC. However, the hypocalcemic effect of denosumab is potentially higher in the setting of renal failure and in these cases a 50% dose reduction is recommended. However, non-specific MRI findings including changes in periventricular white matter and abnormal T2 signal may be present. Antibody markers: Serum and CSF anti-neuronal antibodies. 2, Stoliarova O.Yu. For paraneoplastic limbic encephalitis, anecdotal reports suggest that the best chance to affect neurologic outcome depends on prompt diagnosis, early treatment of tumor, and possibly the use of immunotherapy. Negative initial screening deserves investigation for occult malignancy every 6 months for at least 2 years after onset of LEMS. The syndrome lacks ocular involvement and rarely affects the respiratory musculature. Annual incidence of LEMS is 0.6 case per million, and prevalence is 2.8 cases per million in the US. Paraneoplastic syndromes are most commonly associated with lung cancer, reported in approximately 10% of the cases. Antiamphiphysin antibodies are present in serum samples of patients with stiff-man syndrome and breast cancer or, less frequently, in patients with encephalomyelitis associated with small cell lung cancer. Paraneoplastic syndrome associated with desquamative interstitial pneumonia mimicking lung cancer: A case report April 2008 Turkish Journal of Cancer 38(2):78-82 The severity of symptoms is related to the rate of sodium decline, the level of serum sodium, and the age of patients. Initial evaluation of the patient with lung cancer: symptoms, signs, laboratory tests, and paraneoplastic syndromes: aCCP evidenced-based clinical practice guidelines (2nd edition). If imaging and bronchoscopic studies are negative and the patient is high risk, consider periodic surveillance. Anti-Hu antibodies are present in up to 80 percent of small-cell lung carcinoma-associated limbic encephalitis though these markers may also be detected in neuroblastoma and prostatic cancer. However, LEMS associated with NSCLC is also reported. If tolerated, the dose may be increased by 50 mg every week to 1.5 mg/kg/day, and to a maximum dose of 2.5 mg/kg/day if patients do not respond to lower doses after 2-3 months. Chest 2007;132:149S-60S. 1).Patients can present with multiple paraneoplastic syndromes … Ectopic Cushing Syndrome is the second most common paraneoplastic syndrome in SCLC patients after SIADH. SUMMARY: Paraneoplastic syndromes are systemic reactions to neoplasms mediated by immunologic or hormonal mechanisms. Initial evaluation of the patient with lung cancer: symptoms, signs, laboratory tests, and paraneoplastic syndromes… SIADH can be difficult to treat as a paraneoplastic syndrome, especially if the … Chest imaging is indicated if no diagnosis of malignancy has been made in the setting of this condition, as the condition may precede development of cancer by two years. Anti-amphiphysin is associated with stiff-person syndrome and may be seen in breast cancer and small-cell lung cancer. It will detect early changes, including hyperintense signals in the medial aspect of temporal lobes that are better seen in T2 and FLAIR sequences and do not enhance with contrast. Demeclocycline at doses of 150 to 300 mg orally, in divided doses 3-4 times per day is a renal toxin that inhibits AVP action in the kidney and enhances free water clearance over 7-14 days of use. Annual incidence of LEMS is 0.6 case per million, and prevalence is 2.8 cases per million in the US. Ketoconazole is effective at doses of 400-1600 mg/day, in divided doses every 6-8 hours and may cause elevated liver enzymes and hepatic injury, gastrointestinal side effects, hypogonadism and gynecomastia. Proc. Antibodies associated and specific for myositis: Anti-Jo-1 and other anti-synthetase antibodies, Antibodies against the Mi2, SRP, PM/Scl, and Ku antigens, Erythrocyte sedimentation rate is elevated. Another antiresorptive agent is denosumab, which is a human monoclonal antibody to RANKL, and reduces osteoclastic bone resorption. Paraneoplastic syndromes occur in up to 15% of patients with cancer 3. Some examples are given below 1,2: Paraneoplastic comes from the Greek words for alongside (para), new (neo) and formation (plasis) 2. Hypertonic saline infusion is typically reserved for severe refractory hyponatremia, and hyponatremia that presents with marked alteration of mental status or seizure. The Licensed Content is the property of and copyrighted by DSM. POMS is poorly responsive to immunotherapy and treatment of the underlying malignancy is the best approach to managing paraneoplastic opsoclonus-myoclonus. Inferior petrosal vein sampling of ACTH is often required to definitively exclude a pituitary source of ACTH and confirm ectopic ACTH secretion when the diagnosis cannot be made on clinical grounds alone. What diagnostic procedures will be helpful in making or excluding the diagnosis of a paraneoplastic syndrome associated with lung cancer? Copyright © 2017, 2013 Decision Support in Medicine, LLC. Those with small-cell lung cancer are at greater risk. Finally, paraneoplastic syndromes may also include other non-specific symptoms such as tumor fever, lactic acidosis, and hypouricemia. Once suspected or once a diagnosis of subacute cerebellar degeneration is made, blood and CSF analysis for autoantibodies are warranted and can aid the determination of the underlying primary malignancy (e.g., anti-Hu antibodies in small cell lung cancer). Other diseases or conditions that can mimic paraneoplastic opsoclonus-myoclonus include cerebrovascular disease, meningoencephalitis, and cerebral mass lesions. Zalatnai A, Perjési E, Galambos E. Much More than Trousseau Syndrome. Small cell lung cancer (SCLC) is the most frequent cancer histology associated with paraneoplastic syndromes. 2010;85 (9): 838-54. Somatostatin analogues (SSAs) and dopamine agonists have been used, alone or in combination with adrenolytic agents, for patients with recurrence, incomplete resection or occult tumours. Abstract: Paraneoplastic syndromes (PNS) associated with lung cancer are well recognised, are often complex to diagnose, and have minimal evidence to promote nursing and medical management. Plasmapheresis has shown a response rate of up to 40%. Bronchoscopy, EBUS-guided transbronchial needle aspiration, CT-guided transthoracic needle biopsy, thoracoscopic lung biopsy, or mediastinoscopy can be used to obtain tissue for diagnosis of primary malignancy. Electrocardiogram findings: prolonged PR and QRS intervals, shortening of QT interval, bradycardia, and heart block are found on electrocardiogram. Despite the effectiveness of mitigating the symptoms and morbidity associated with ECS, survival of patients with ECS after successful bilateral adrenalectomy remains less than 60% at 2 years, mainly due to cancer-specific mortality associated with the underlying disease. Once this condition is suspected, a CSF analysis to exclude other inflammatory and infectious etiologies is indicated. Breast cancer related neurologic paraneoplastic syndromes includes sensory and motor-type neuropathies, paraneoplasic cerebellar degeneration, opsoclonus–myoclonus syndrome (OMS), stiff person syndrome, encephalomyelitis and paraneoplastic retinopathy [4, 5]. © 2017, 2013 Decision Support in Medicine LLC with adrenal insufficiency are the classical findings of SIADH several autoantibodies!
