Wolfgang Wick, Anne Hertenstein, Michael Platten
Neurological complications of cancer and of anticancer treatments can be substantially disabling to patients, especially with classic chemotherapies. As a rare but important complication, targeted therapies might also result in similar unwanted effects, partly because inhibition of VEGF is a common downstream effect. Therapeutic antibodies, such as the CD20-depleting antibody rituximab, and underlying haematological malignancies, can induce long-lasting cellular immunosuppression, predisposing patients to opportunistic CNS infections, such as progressive multifocal leukoencephalopathy, where treatment-induced recovery can result in severe reconstitution of immune inflammatory syndromes of the central nervous system...

INTRODUCTION: Xeroderma pigmentosum is a rare autosomal recessive genetic disease. This disease predisposes patients to early-onset skin cancers, particularly squamous cell carcinoma. Here, we report 3 pediatric cases, including 2 deaths. OBSERVATION: The subjects included 2 boys and 1 girl with skin type VI. All subjects were from consanguineous marriages, and the average age was 7.6 years. The patients all had ulcerative budding tumor lesions in the cephalic region, and the mean disease duration was 18 months...

OBJECTIVE In 1999, the World Health Organization categorized large cell neuroendocrine carcinoma (LCNEC) of the lung as a variant of large cell carcinoma, and LCNEC now accounts for 3% of all lung cancers. Although LCNEC is categorized among the non-small cell lung cancers, its biological behavior has recently been suggested to be very similar to that of a small cell pulmonary malignancy. The clinical outcome for patients with LCNEC is generally poor, and the optimal treatment for this malignancy has not yet been established...

Pseudo-achalasia with lung cancer is a rare complication. We present 2 cases of pseudo-achalasia with lung cancer and summarize previous reports. The previous reports suggested that lung cancer can be complicated with pseudo-achalasia caused by paraneoplastic neurological syndromes rather than direct invasion of the tumor cells to the lower esophageal sphincter, irrespective of the histology of the lung cancer; this can strongly influence the performance status. Treatment for pseudo-achalasia improves not only the symptoms, but also the performance status...

Exosomes are membrane-enriched extracellular vesicles with a proposed diameter in the range of 30-100 nm. They are released during both normal homeostasis as well as under pathological conditions by most cell types. In recent years, there has been robust interest in the study of these vesicles as conduits for the delivery of information between cells in both analogous as well as disparate tissues. Their ability to transport specialized cargo including signaling mediators, proteins, messenger RNA and miRNAs characterizes these vesicles as primary facilitators of cell-to-cell communication and regulation...

Acute central nervous system (CNS) toxicity and immune-related side effects are increasingly recognized with the use of monoclonal antibodies for cancer therapy. Here, we report a patient who developed of acute-onset encephalopathy and coma, which began shortly after administration of panitumumab for the treatment of metastatic colorectal cancer. Echocardiography revealed that the drug had been infused into the left cardiac ventricle via a dislocated central venous line. Diffusion-weighted magnetic resonance imaging disclosed multiple cortical hyperintensities, which were preferentially located in the frontal lobes...

PURPOSE: One among seven women will present with breast cancer for which major therapeutic advances led to a significant increase in survival and cure rates. During or after cancer treatment, severe complications may occur requiring admission in intensive care unit (ICU). Intensivists could be reluctant for accepting cancer patients in the ICU, and there are very few data about causes of admission and prognosis of patients with breast cancer admitted in the ICU for an acute complication...

Acute intermittent porphyria (AIP) is an autosomal dominant metabolic disease caused by hepatic deficiency of hydroxymethylbilane synthase (HMBS), the third enzyme of the heme synthesis pathway. The dominant clinical feature is acute neurovisceral attack associated with high production of potentially neurotoxic porphyrin precursors due to increased hepatic heme consumption. Current Standard of Care is based on a down-regulation of hepatic heme synthesis using heme therapy. Recurrent hyper-activation of the hepatic heme synthesis pathway affects about 5% of patients and can be associated with neurological and metabolic manifestations and long-term complications including chronic kidney disease and increased risk of hepatocellular carcinoma...

BACKGROUND: Renal cell carcinoma (RCC) is among the 10 most common cancers in both men and women. It comprises 2-3% of all malignancies. The most common site for metastasis from RCC is the lung (50% of patients), followed by the skeleton (20% to 50% of patients). METHODS: We retrospectively reviewed our consecutive series of 63 patients surgically treated for spinal metastases from RCC. The surgical treatment for spinal metastases varied in each patient. Factors influencing the choice of surgery included age, disease status, symptoms, morbidity of the patient, the location, the number of repetitive lesions and the existence of extra-osseous metastases...

Low-grade (WHO I-II) gliomas and glioneuronal tumors represent the most frequent primary tumors of the central nervous system in children. They often have a good prognosis following total resection, however they can create many neurological complications due to mass effect, and may be difficult to resect depending on anatomic location. MicroRNAs have been identified as molecular regulators of protein expression/translation that can repress multiple mRNAs concurrently through base pairing, and have an important role in cancer, including brain tumors...

A 44-year-old woman with a history of von Hippel-Lindau (VHL) disease, a rare inherited neoplasia syndrome, presented acutely to hospital with a productive cough, symptoms of respiratory tract infection and odynophagia (painful swallowing). A chest X-ray confirmed right-sided pneumonia. Investigation of the persistent odynophagia using barium swallow revealed aspiration of the contrast into the lungs and suggested a neurological cause for her chest infection. Clinical assessment and speech and language therapy confirmed a pseudobulbar palsy...

INTRODUCTION: To examine the infectious outcomes after the insertion of the temporary prostatic urethral stent (TPUS) in benign prostatic hyperplasia (BPH) patients. MATERIAL AND METHODS: Between November 2007 and September 2012, ninety TPUS were used in 33 patients with BPH at our institution. All patients had negative urine cultures prior to the first stent insertion. TPUS were sent for cultures at time of removal or exchange. Stents were removed at the time of definite surgical intervention, at 4-6 weeks, or when patients elected another course of treatment...

PURPOSE OF REVIEW: The purpose of this review is to provide a practical clinical approach to confusion in the patient with cancer. Confusion in the cancer population has a broader differential diagnosis than in the general medical population. The clinician must consider the usual differential diagnoses as well as causes unique to the cancer patient including direct complications from the cancer and indirect complications related to cancer treatment. RECENT FINDINGS: In the recent age of precision medicine, the oncologist now utilizes the genomic profile of both the patient and the tumor to provide advanced biologic therapies including targeted anticancer drugs, antiangiogenic agents, and immunotherapy...

Chronic systemic inflammation (CSI) has recently been identified as a major contributor to common diseases ranging from cancer to metabolic disorders and neurologic alterations. In the last decade, we and others have generated genetically engineered mouse models for inflammatory diseases, which enable studying the molecular mechanisms of CSI. Recently, organ cross-talk induced by CSI under homeostatic and pathological conditions has begun to be appreciated. In this review, we will revisit whole organism physiology in relation to CSI originating from epithelial tissues, such as the skin and gut...

The amount of people living with cancer is increasing; they live longer and have thus a higher risk of developing neurological complications. Magnetic resonance as a diagnostic procedure of choice in detecting the reasons of neurological/psychiatric symptoms in oncological patients is nowadays relatively easily accessible. Early diagnosis established by radiologists familiar with neurological entities that may follow cancer treatment allow clinicians to provide proper treatment, even if the diagnosis seems unbelievable...

The pleiotropic cytokine interleukin 2 (IL2) disrupts the blood-brain barrier and alters brain microcirculation, underlying vascular leak syndrome that complicates cancer immunotherapy with IL2. The microvascular effects of IL2 also play a role in the development of multiple sclerosis and other chronic neurological disorders. The mechanism of IL2-induced disruption of brain microcirculation has not been determined previously. We found that both human and murine brain microvascular endothelial cells express constituents of the IL2 receptor complex...

We aimed to reappraise whether post-stereotactic radiosurgery (SRS) results for brain metastases differ between patients with and without neurological symptoms. This was an institutional review board-approved, retrospective cohort study using our prospectively accumulated database including 2825 consecutive BM patients undergoing gamma knife SRS alone during the 15-year period since July 1998. The 2825 patients were divided into two groups; neurologically asymptomatic [group A, 1374 patients (48.6 %)] and neurologically symptomatic [group B, 1451 (51...
