POEMS syndrome: clinical update.

J Neurol 2018 Nov 29. Epub 2018 Nov 29.

Department of Neurology, Royal Free Hospital, Pond Street, London, NW3 2QG, UK.

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes) is a rare paraneoplastic syndrome, caused by a plasma cell proliferative disorder, which is most commonly lambda restricted. The neurological hallmark, which forms one of the mandatory criteria for diagnosis, is a subacute onset demyelinating neuropathy, which can be rapidly disabling and painful. A number of multi-system features are also characteristic of this disorder, and certainly not restricted to those included in its acronym, which though limited, remains a useful and memorable name, helping distinguish POEMS syndrome from other paraproteinaemic neuropathies.

Beyond the Dual Paraneoplastic Syndromes of Small-Cell Lung Cancer with ADH and ACTH Secretion: A Case Report with Literature Review and Future Implications.

Case Rep Oncol Med 2018 18;2018:4038397. Epub 2018 Oct 18.

Department of Medicine, Baystate Medical Center, University of Massachusetts Medical School, Springfield, MA, USA.

We present a case of small-cell lung cancer (SCLC) with syndrome of inappropriate antidiuretic hormone secretion (SIADH) in which serum sodium gradually normalized with the onset of hypertension, refractory hypokalemia, and chloride-resistant metabolic alkalosis due to ectopic adrenocorticotrophic hormone (ACTH) secretion (EAS). In this case report, we discuss the diagnostic challenges of dual paraneoplastic syndromes with SIADH and EAS, management of SCLC with paraneoplastic endocrinopathies, and their prognostic impact on SCLC. In addition, we discuss neuroendocrine differentiation and ectopic hormone production in relation to intratumoral heterogeneity in SCLC and propose tumor microenvironment and hormonal and metabolic dependence as important determinants of tumor growth and survival.

Checkpoint inhibitor use in two heart transplant patients with metastatic melanoma and review of high-risk populations.

Melanoma Manag 2018 Dec 26;5(4):MMT10. Epub 2018 Oct 26.

Duke Cancer Institute, Duke University Medical Center, Durham, NC, USA.

Due to the unique side-effect profile of immune checkpoint inhibitors (ICIs), groups of patients deemed to be at high risk of complications were excluded from trials that proved the efficacy and safety of these agents in patients with various malignancies. Among these excluded patients were those with prior solid organ transplantation, chronic viral infections and pre-existing autoimmune diseases including paraneoplastic syndromes. We present follow-up on a patient from a previously published case report with an orthotopic heart transplantation who was treated with both cytotoxic T-lymphocyte antigen 4 and PD-1 inhibition safely, without organ rejection.

Diagnosis of Autoimmune Blistering Diseases.

Front Med (Lausanne) 2018 2;5:296. Epub 2018 Nov 2.

Department of Dermatology, University of Lübeck, Lübeck, Germany.

Autoimmune skin blistering diseases (AIBD) are characterized by autoantibodies that are directed against structural proteins in the skin and adjacent mucous membranes. Some clinical signs are typical for a specific AIBD, however, correct diagnosis requires the detection of tissue-bound or circulating autoantibodies. The gold standard for diagnosis of AIBD is the detection of autoantibodies or complement component 3 by direct immunofluorescence (DIF) microscopy of a perilesional biopsy. Read More

J Neuroimmunol 2018 Nov 8;326:14-18. Epub 2018 Nov 8.

Department of Pathology, Nottingham University Hospitals NHS Trust, Queen's Medical Centre, Nottingham NG7 2UH, UK.

Antibodies to SOXB1 proteins in patients with paraneoplastic disorders are associated with small-cell lung cancer (SCLC), particularly in Lambert-Eaton myasthenic syndrome (LEMS). We aimed to establish if SOX2 antibodies could be used to identify SCLC and other tumours found in a range of paraneoplastic disorders and controls. SOX2 antibodies were detectable in 61% of patients with LEMS-SCLC, and in other paraneoplastic disorders, such as opsoclonus-myoclonus and paraneoplastic cerebellar degeneration, only when there was an underlying SCLC.

Paraneoplastic syndrome as the presentation of limited stage small cell carcinoma.

BMC Pulm Med 2018 Nov 14;18(1):169. Epub 2018 Nov 14.

Department of Pulmonary and Critical Care Medicine, Arrowhead Regional Medical Center, Colton, California, USA.

Background: Small cell lung carcinoma (SCLC) is one of the deadliest forms of lung cancer due to its poor prognosis upon diagnosis, rapid doubling time, and affinity for metastasis. As 60-70% of patients with SCLC have disseminated disease upon presentation, it is imperative to determine the extent of disease burden for treatment. As a neuroendocrine carcinoma, clinicians must pay close attention to abnormal findings in a smoker that could lead to earlier diagnosis and better prognostication. Read More

Neurology Division, Hospital das Clínicas, University of São Paulo School of Medicine, Sao Paulo, Brazil.

The disorders of the central nervous system associated with cancer by remote immune-mediated mechanisms are a heterogeneous group. These disorders encompass the classic paraneoplastic disorders and the recently recognized autoimmune encephalitis associated with antibodies against neuronal cell surface or synaptic proteins that occur with or without cancer association. In the last decade, the new surge of interest in neuronal diseases associated with anti-neuronal antibodies led to the rapid discovery of new forms of disease that have different manifestations and were not previously suspected to be immune mediated.

Nonislet-cell tumor hypoglycemia (NICTH) is a rare paraneoplastic phenomenon well described in dogs and humans. Tumors associated with NICTH secrete incompletely processed forms of insulin-like growth factor-II (IGF-II), commonly named big IGF-II. These forms have increased bioavailability and interact with the insulin and IGF-I receptor causing hypoglycemia and growth-promoting effects. Read More

The blood-brain barrier (BBB) disruption is a critical step in paraneoplastic neurological syndrome (PNS) development. Several cytokines have been implicated in BBB breakdown. However, the exact step-by-step mechanism in which PNS develops is unknown, and the relationship between a systemic neoplasm and BBB is multilevel. Read More

Patients with malignant tumors may present with joint pain or arthritis(paraneoplastic arthritis). It needs to be carefully determined whether these symptoms are related to the malignant tumor, due to a concomitant rheumatoid disease, due to an adverse reaction to treatment, or due to a relapse. It can be relatively easy to diagnose paraneoplastic syndrome when there is clearly a malignant tumor present or typical symptoms are exhibited. Read More

Tumor-induced osteomalacia(TIO)is a paraneoplastic syndrome caused by excessive production and secretion of fibroblast growth factor 23(FGF23)from causative tumors which induces hypophosphatemia and osteomalacia. Mesenchymal benign tumors in bone or soft tissue are the most frequent causes for TIO. The first choice treatment of TIO is complete resection of the responsible tumors. Read More
