Clinical Oncology - 2015;2(02)

[Cancer anorexia-cachexia syndrome (CACS) defi ned by ongoing loss of skeletal muscle mass, with or without loss of fat mass. In contrast to serious non tumorous cachexia it can not be reversed by conventional nutritional support. CACS affects most of cancer patients and has negative impact on physical function, anticancer treatment response, quality of life and survival. It is known that interactions between tumor and reactive host cells are responsible for tumor progression, metastasis formation and chronic infl ammation, as well. All of the processes are induced by cytokines. The CACS associated changes in carbohydrate, protein and lipid metabolism are caused by the elevated level of infl ammatory cytokines. The new anti-CACS drug development aimed at normalizing of the pathologic pathways. Up to now, megestrol-acetate (MA) administration seems to be the most effective drug in CACS treatment. MA has dual effect, stimulates the NPY activation and inhibits the synthesis and expression of infl ammatory cytokines. Its clinical effects are on line with the aboves, improves appetite, calorie intake and increases body weight. There is paradigm shift in CACS treatment, the traditional nutritional support is replaced by combination of pharmaceutical interventions, nutritional support and use of dietary supplements.]

[Diagnosis and therapy of childhood brain tumors – an update]

GARAMI Miklós

[Childhood cancers are rare disorders. The average annual age-standardized incidence is 149/1000000 (0-14 yrs). Diagnosis of childhood brain tumors, despite the specifi c localization and advanced imaging techniques can cause diffi culties. In recent years, due to better early recognition, number of surgically removable brain tumors is increasing. Early detection of the disease (clinical knowledge), use of modern imaging (fMRI) techniques and detection of characteristic molecular lesions allow up-to-date diagnosis and successful treatments. These approaches provide the basis for risk-adapted personalized treatment options]

[Circulating tumor cells - a promising new approach]

KOPPER László

[It is an old observation, that tumor cells can escape from the primary, travel with the circulation, and fi nally be arrested in distant places. To know the potential „advantage” of this phenomenon (circulating tumor cells, CTC) is very important. One of the key questions is the proper sensitivity of isolation and characterisation techniques being able to represent the heterogeneity of tumorous clones. There is no doubt that the time arrived for the application of minimal invasive markers in oncology, with the hope that the survival of the patients can be improved using real-time monitoring and more effective therapy. The analysis of CTCs/cfDNA and other markers (e.g. miRNA, exosomes) obtained from the blood will be, hopefully, rutine tool in designing therapeutic strategy, and monitoring tumor response.]

[The incidence of thyroid cancers increased signifi cantly over the past few decades, but the mortality rate decreased. The clinical course and therapy for the three types of thyroid cancer (differentiated, medullary and anaplastic) are different. The medical therapy consists of levothyroxin therapy, conventional chemotherapeutic agents and tyrosin kinase inhibitors. The aim of this review is to summarize the therapeutic options of each histological subtype.]

[How the molecular informations infl uence the therapeutic strategy against colorectal cancer?]

AXEL Grothey

[Colorectal cancer is not a homogenous disease, but it has different subgroups based on their molecular characteristics. NCCN and ESMO guidelines emphasize the importance of the determination of RAS and BRAF mutations in those patients who are intended to treat with targeted therapy. The increase in knowledge on the molecular changes will help to design and start a new generation of clinical trials, which will be designed not on their randomization of large groups of unselected patients, but rather on the consideration of the molecular subgroups determined before introducing therapy.]

[Invasive endoscopy in oncology]

MADÁCSY László

[Recent advances in interventional gastrointestinal endoscopy have led to a large variety of new diagnostic and minimally invasive endoscopic surgical procedures in oncological patients. Endoscopic ultrasound with the possibility of fi ne needle aspiration is currently one of the most accurate imaging technology for adequate staging of gastrointestinal cancers including oesophageal, gastric, rectal and pancreatic cancer. Endoscopic mucosal resection and endoscopic submucosal dissection offers a minimal invasive endoscopic treatment modality as an alternative for laparoscopic surgery for patients with early intramucosal neoplasias, fl at adenomas and laterally spreading tumors of the oesophagus, stomach, duodenum and colorectum. Self-expandable metal stents are now readily available for endoscopic palliation of different type of malignant gastrointestinal obstructions including oesophageal, duodenal, colonic and biliary stenosis. These recent developments of interventional gastrointestinal endoscopy lead to more precise and accurate tumor staging and more effective oncological therapy for patients with gastrointestinal cancers.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

Autonomic nervous system may be affected after carpal tunnel syndrome surgery: A possible mechanism for persistence of symptoms after surgery

ONDER Burcu, KELES Yavuz Betul

After carpal tunnel surgery, some patients report complaints such as edema, pain, and numbness. Purpose – The aim of this study was to evaluate autonomic nervous system function in patients with a history of carpal tunnel surgery using sympathetic skin response (SSR). Thirty three patients (55 ±10 years old) with a history of unilateral operation for carpal tunnel syndrome were included in the study. The SSR test was performed for both hands. Both upper extremities median and ulnar nerve conduction results were recorded. A reduced amplitude (p=0.006) and delayed latency (p<0.0001) were detected in the SSR test on the operated side compared to contralateral side. There was no correlation between SSR and carpal tunnel syndrome severity. Although complex regional pain syndrome does not develop in patients after carpal tunnel surgery, some of the complaints may be caused by effects on the autonomic nervous system.

To handle the HaNDL syndrome through a case: The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis

ÇOBAN Eda, TEKER Ruken Serap, SERİNDAĞ Helin, SAKALLI Nazan, SOYSAL Aysun

The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HaNDL) is a rare entity. This disease has been related to migrainous headaches. It is a benign, self-limited disorder, which is characterized by fluctuating neurological symptoms and cerebrospinal fluid lymphocytosis. We describe a case of a 47 years old man with acute onset of headache and aphasia. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis (25 cells/μl, 100% lymphocytes). Electroencephalogram showed moderate slow rhythm in the left hemisphere, with temporoparietal predominance, and without epileptiform activity. His blood tests as well as magnetic resonance imaging (MRI) results were normal. With the diagnosis of HaNDL syndrome the patient was accepted in the Department of Neurology and discharged with full recovery.

[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]
