Clinical Oncology - 2016;3(03)

[Biomarkers (tumor markers in oncology) are able to make exact, objective and reproducible distinction between two groups. Biomarkers can serve different purposes, as to estimate the patient’s survival without treatment (prognostic marker), to select those patients who would respond optimally to treatment (predictive marker), to follow the patient in order to detect of a relapse (monitoring marker), helping identifi cation the tumor-type (diagnostic marker). The main task for a biomarker is to find the best treatment with less toxicity. The main enemy of biomarkers is the heterogeneity of the tumor, the continuous change in its geno- and phenotype, which can explain the low sensitivity and specifi city. More attention should be given to standardization and validity. It is highly possible, that biomarker-panel as well as marker-based clinical trials will be used in the near future.]

[Therapy of endometrial cancer - an update]

SIPOS Norbert

[Endometrial cancer is the most frequent gynecologic malignancy in developed countries. Recently, there is a signifi cant increase of incidence caused by epidemic obesity. While the etiology of endometrial cancer can be heterogeneous, the effective therapy should be rather personalized. The primary therapy of endometrial cancer is operative. The recommended surgery is total abdominal hysterectomy and bilateral salpingo-oophorectomy. Management of pelvic and paraaortic lymphadenectomy is supported by the latest international recommendations, except cases of low-risk tumors (stage I/A, grade 1 or 2, endometrioid type, diameter of tumor <2 cm). Method of adjuvant therapy, especially in developed stages, is still controversial. Efficacy of postoperative irradiation, chemotherapy and chemoirradiation is under investigation by several ongoing studies. Recurrent endometrial cancer has bad prognosis, the best solution in this case is chemotherapy. In recent years targeted therapy (especially antiangiogenetic drugs, mTORinhibitors and hormontherapy) gave us some promising results. Around 80% of endometrial cancers can be diagnosed at early stages and cured with efficacy. Unfortunately, there is a group of tumors with bad prognosis, low differentiation, or recurrency, which can be a real challenge for clinicians. In this review we discuss the latest and most promising studies and scientifi c results in connection with treatment of high-risk endometrial cancers.]

[Obesity and cancer]

VALTINYI Dorottya

[The role of obesity in the development of cancer is well-known from ages. However, these days we witness the explosion-like increase of obesity, globally, but mainly in the economically advanced population, and, which is even more alarming, among youngsters. The prognosis of the obesity-related cancer is rather poor, therefore, the prevention, including the screening, have outstanding importance. Unfortunately, the participation of the obes persons, especially obes women, in these programs is very low. The diagnostics and therapies should consider the special features of obesity, which are related to the magnitude, distribution, composition of fatty tissue connected to the changes in pharmacokinetics. Moreover, the problems might be complicated with obesity-associated non-tumorous severe diseases (e.g. cardiovascular, diabetes type 2).This review covers different aspects of obesity-cancer relationships, with an emphasis on everyday oncology.]

[Novelties in the management of Hodgkin lymphoma]

ILLÉS Árpád, MOLNÁR Zsuzsa, MILTÉNYI Zsófia

[Hodgkin lymphoma is a lymphoproliferativ disease, it is about 12-18% of all lymphomas. It has typical morphologic, clinical and therapeutic features, which can distinguish from other lymphoma types. Due to risk- and PET/CT adapted treatment Hodgkin lymphoma is a curable lymphoma with an 80-90% long-term survival, however, refracter- and relapsed patients’ therapy is a great challange. Cure rate can increase due to the development of the diagnostic and treatment modalities, but the use of standard recommendation is necessary. The aim of this review is to show new WHO 2016 lymphoma classifi cation, role of the new diagnostic options, especially 18FDG-PET/CT, Lugano classifi cation and fi rst-line and salvage therapeutic possibilities and to introduce the immunotherapy, like brentuximab vedotin and PD1 inhibitors. Certain points of hemopoietic stem cell transplantation will be also covered.]

[Controversies in neurology: Diagnosis, follow up and therapy of multiple sclerosis with pathomechanismal approach]

VÉCSEI László

[The clinical boundaries between the relapsing and progressive course of multiple sclerosis are often indistinct. Despite the variable patterns of evolution, there are no biological reasons for discerning different multiple sclerosis phenotypes. Indeed, both primary progressive and secondary forms of the disease share similar pathological features in respect of the extent of inflammatory infiltrates, axonal damage, and cortical demyelination. The data indicating that primary progressive multiple sclerosis is preceded by an asymptomatic relapsing remitting phase. The proposed definition of secondary progressive multiple slcerosis, the attainment of at least EDSS of 4 is required to mark the transition to the progressive phase. Therefore, the clinical progress can be uncovered in the early phase of the disease. Furthermore, a continuous progression independent of relapsing activity is commonly observed during the relapsing remitting phase. A continuous smouldering process underpins the subtle clinical deterioration, which stands out as an important unmet treatment target. Concerning cognitive dysfunction of the patients pro-inflammatory cytokines have been associated with worse cognition in active multiple sclerosis, and this inflammatory milieu could also contribute to altered mentation during relapses. Therefore, long before people with multiple sclerosis become physically disabled, they have usually acquired hidden disabilities related to cognitive impairment. Silent progression appears during the relapsing remitting phase and it associates with brain atrophy. This suggests that the same process that underlies secondary progressive multiple sclerosis likely begins far earlier than is generally recognized. This supports a unitary view of multiple sclerosis biology. ]

[Current questions of multiple sclerosis: the secunder progressive form of the disease]

VÉCSEI László

[Recent data suggest that long-term worsening is common in relapsing-remitting multiple sclerosis patients and is largely independent of relapses or new lesion formation on brain MRI. The current definition of secunder progressive multiple sclerosis is worsening of disability independent of relapses over at least 6-month interval. Early focal inflammatory disease activity and spinal cord lesion are predictors of very-long term disease outcomes in relapse - onset multiple sclerosis. The potential of PET imaging to visualize hidden inflammation in MS brain in vivo is an important contribution for better understanding the progression of the disease. Therefore, PET imaging is a promising tool in detecting the conversion from relapsing remitting multiple sclerosis to secunder progressive form of multiple sclerosis. Furthermore, neuro-axonal damage is the pathological substrate of permanent disability in different neurological disorders including multiple sclerosis. The neurofilament proteins have promise in this context because their levels rise upon neuro-axonal damage not only in the cerebrospinal fluid but also in blood. Patients with increased serum levels of neurofilament at baseline, independent of other clinical and MRI variables, experience significantly more brain and spinal cord volume loss over 2 years and 5 years of follow-up. The kynurenine-pathway abnormalities may be associated with the swich from early-mild stage multiple sclerosis to debilitating progressive forms of the disease. Analysis of these metabolites in serum may have application as multiple sclerosis disease biomarkers. Free radical action has been suggested as a causal factor in the illness. Increased free radical production and consumption of the scavenger molecules were found during the active phase of the disease. Based on the clinical findings (EXPAND Study) and pathomechanism of the disease siponimod is approved by the US Food and Drug Administration for the treatment of relapsing remitting forms of multiple sclerosis, to include secunder progressive multiple sclerosis with active disease, relapsing-remitting multiple sclerosis and clinically isolated syndrome.]

Independent validation of the Quality of Life in Essential Tremor Questionnaire (QUEST)

KOVÁCS Márton, MAKKOS Attila, JANSZKY József, KOVÁCS Norbert

Quality of Life in Essential Tremor Questionnaire (QUEST) was specially developed for essential tremor population to measure the health-related quality of life. Besides the development of the Hungarian version, we performed an independent testing of the scale adding further information on its clinimetric properties. In this study 133 ET patients treated at University of Pécs, Hungary, were enrolled. Besides QUEST, we assessed Patient’s Global Impression-Severity (PGI-S) and Fahn-Tolosa-Marin Tremor Rating Scales. After the independent validation in accordance to the Classic Theory of Tests, we evaluated cut-off values for detecting clinically meaningful ET-related disabilities based on receiver operating characteristics analysis. Cronbach’s a was 0.897. QUEST demonstrated high convergent validity with PGI and divergent validity with disease-duration, positive family history, need for deep brain stimulation surgery, and the presence of depression and anxiety. Presence of moderate ET-related disabilities was identified by scores > 11.25 points on QUEST-SI (sensitivity: 77.4%, specificity: 83.3%); whereas scores > 20.35 points indicated severe ET-related disabilities (sensitivity: 83.3%, specificity: 59.1%). We demonstrated that the fundamental clinimetric properties of the QUEST are satisfactory.

Since the definite diagnosis of Creutzfeldt-Jakob disease (CJD) can currently only be provided by autopsy, there is a special need for fine diagnostic tools in live patients to achieve accurate diagnosis as early as possible. The aim of this study was to perform a preliminary retrospective analysis on the utility of the measurement of total Tau (tTau) and some other biomarkers from the cerebrospinal fluid (CSF) of patients with rapidly progressive dementia in the diagnostic work up of CJD. Beside the assessment of relevant clinical data and the findings of electroencephalography and brain magnetic resonance imaging, the presence of 14-3-3 protein and the levels of tTau were determined by Western blot technique and enzyme-linked immunosorbent assay from the CSF of 19 patients diagnosed with rapidly progressive dementia between the period of 2004-2017 at the Department of Neurology, University of Szeged. This preliminary study provided 100% sensitivity for 14-3-3, and interestingly, only 40% specificity to support the clinical diagnosis of CJD. Regarding tTau, the sensitivity values were calculated to be 100% or 83%, whereas the specificity values were 71% or 86%, depending on the applied cut-off levels. The poor specificity of 14-3-3 is not in line with literature data and may be the result of the small number of patients in the cohort with non-prion disease, predominantly consisting of disorders with considerable tissue damage, whereas tTau presented good sensitivity and specificity values. The combined application of these and novel chemical biomarkers may increase both sensitivity and specificity to a desired level.

[The validation of a disease specific quality of life instrument in patients with psoriatic arthritis]

LOVAS Kornélia, KOÓ Éva, WHALLEY Diane, MCKENNA Stephen, MEADS David, KALÓ Zoltán

[Measuring quality of life (QoL) has a growing importance in the field of health technology assessment. It is especially true for chronic diseases, such as psoriatic arthritis, which has significant impact on patients’ quality of life through the intensity of symptoms and the duration of the disease. The quality of life measurement can only be reliable and valid if an appropriate instrument is used. One of the most critical elements of the validity of quality of life intruments is the method used for adapting the questionnaire to foreign languages. Authors present their results and experience in the Hungarian adaptation of the Psoriatic Arthritis Quality of Life (PSAQoL) questionnaire.]
