[INTRODUCTION - Bortezomib, a first-in-itsclass proteasome-inhibitor drug was registered in 2004 for the salvage treatment of relapsed and/or refractory multiple myeloma. We have been using this drug in our department for the treatment of myeloma patients since 2005. PATIENTS AND METHODS - In this retrospective study, treatment results (response rate, response duration, survival) as well as the complications and side effects were analysed based on 60 myeloma patients treated over a period of 18 months. The patients received at least one full cycle of non-first-line bortezomib-based (predominantly combinational) therapy. RESULTS - At least minimal laboratory and/or clinical response was observed in 47 of the 56 patients who could be analysed. Clinically meaningful (at least partial remission) response was seen in 41 of 56 patients. Immune-fixation negative complete remission was achieved in six patients. Median progression-free survival of our patient population was 13 months (10.8-14.8 months, n=49, adjusted for patients lost in the first 6 weeks and for those with less than 6 weeks of follow-up). As for overall survival, the median has not been reached, while treated patients had an 80.3% probability of survival at one year. CONCLUSIONS - Based on the treatment results of 60 myeloma patients, bortezomibbased therapy is clearly effective in relapsed and/or refractory myeloma.]

[THE PLACE OF DIURETICS IN MODERN HYPERTENSION TREATMENT]

CSIKY Botond

[According to national and international guidelines, thiazide diuretics are considered first-line antihypertensive agents. They lower blood pressure and cardiovascular risk efficiently without serious side effects in low-dose monotherapy or in combination with other antihypertensives. Furthermore, when given in combination with certain antihypertensive agents, a synergistic effect develops. Indapamide is a thiazide-like diuretic, virtually without metabolic side effects. Diuretics may have special benefit in the elderly and in certain target organ damage or concomittant disease (heart failure, hypervolaemia, etc). Adequate use of diuretic therapy can prevent hypertensive end-organ damage and other complications, and improves the patients' quality of life.]

Long-term follow-up results of concomitant chemoradiotherapy followed by adjuvant temozolomide therapy for glioblastoma multiforme patients. The importance of MRI information in survival: Single-center experience

LUKÁCS Gábor, TÓTH Zoltán, SIPOS Dávid, CSIMA Melinda, HADJIEV Janaki, BAJZIK Gábor, CSELIK Zsolt, SEMJÉN Dávid, REPA Imre, KOVÁCS Árpád

Introduction - Glioblastoma multiforme (GBM) is the most common malignant primary anomaly of central nervous system. The GBM infiltrates the nearly sturctures from the initial tumor and its metastatic attribution is well known. The aim of our single-centered retrospective study was to introduce the importance of postoperative medical imaging confirmation of total tumor resection for patient with GBM combined concomitant and adjuvant chemoradiotherapy on a 10 year long patient follow up. Methods - From January 2006 to April 2015 we registered 59 patients with newly diagnosed GBM at the University of Kaposvár Health Center Institute of Diagnostic Imaging and Radiation Oncology. The histological diagnosis was confirmed by a proficient neuropathologist (World Health Organisation WHO; grade IV astrocytoma). According to histological status if the ECOG performance status of patients allowed it the mutidisciplinary oncoteam recommended adjuvant chemoradiotherapy all features strictly by Stupp protocol. (60 Gy dose on the gross tumor volume and 2-3 cm margin for the clinical target volume with parallel 75 mg/m2 TMZ. Four weeks after monotherapial phase patients had to recieve 6 cycles of TMZ first cycle with 150 mg/m2 up to 200 mg/m2). The irradiation was carried out by a conformal three dimensional planning system. Results - 59 patients with the median age of 63 (range 17-84) year. Our sample counted 34 male patients and 25 woman patients. 14 patients underwent gross total tumor resection while, 39 patients underwent partial resection and the rest from our sample 6 patients passed through biopsy. Statistical analysis showed a lengthier survival among males than females, with a median survival of 13 months for males and females, the OS of 26.209 for males, meanwhile 15.625 for females. However, the difference is not considerable (log-rank p=0.203). Our study found that the estimated survival of patients at least 50 years old is significantly shorter at a median survival of 12 months (log rank p=0.027) than that of patients below 50 years of age at a median survival of 23 months. The longest estimated median survival was calculated with patients of ECOG '0' condition (16 months). However, no significant difference was found in the estimated survival of patients of different ECOG conditions (log-rank p=0.146). Based on the extent of surgery, complete resection resulted in the longest average survival of 36.4 months, followed by 21.5 months among patients with biopsy, and 15.8 months among patients with partial resection. Different surgical procedures, however, did not result in significant differences in survival (log-rank p=0.059). The overal survival of patients who had complete resection confirmed by MRI compared with the overal survival of patients with residual tumor confirmed by MRI as well we can estimate that there is significant difference between these two groups (p=0,004). Conclusion - Despite complex and intense treatment, recurrence is inevitable and causes relatively rapid death. In our analysis complete resection, as defined from the neurosurgeon’s report and postoperative MRI, resulted in an independently significant improvement in OS. Our results are the evidences that the treatment of patients with glioblastoma multiforme in Hungary is at least on the same level as any other developed European countries.

[The aim of our research was to assess the incidence and the 12- and 24-month mortality of hospitalized stroke in Hungary. We analyzed the rate of mortality after stroke and compared it to the standard mortality rate of the population. To assess the incidence we extracted the data of “new” stroke patients (ICD- 10 diagnoses: I60-64) hospitalized in May 2003 from the database of the National Health Insurance Fund Administration. We regarded those as “new” patients who had not been treated with these primary or secondary diagnoses in the previous 24 months. Data were collected by sex and age (age groups: 25-44, 45-64, 65 and over). We analyzed the patients' survival on the basis of their April 2004 and April 2005 data. The incidence of the “new” hospitalized stroke patients was higher in men than in women; the incidence in the age group of 65 and over was 2112/100.000 in males and 1582/100.000 in females, the corresponding values in the 45-64 age group were 623 vs. 366 per 100.000, respectively. In 2003 more than 42 thousand “new” stroke patients were hospitalized in Hungary of whom over 10 thousand died in the first year, followed by a further 2 thousand in the second year. Women’s survival is more favourable than men's: in the first year it is 71.47% vs. 69.24% (65+ group), and 88.18% vs. 83.16% (45-64 group); in the second year the corresponding values are 66.95% vs. 61.62% (65+), and 85.45% vs. 80.90% (45-64), respectively. The risk of death in the first year after stroke, compared to the standard population, is 5.17- fold in women and 4.70-fold in men in the total sample, and 10-15-fold in the 45-64 group. There are large differences by gender, particularly in men of the working age groups (25-44, 45-64), whose mortality is twice as high as that of women of the same age.]

[Cancer-treatment induced peripheral neuropathy]

DEMETER Gyula

[Peripheral neuropathy is caused by structural or functional damage of nervous system. The pathophysiology is not well known. Its clinical features are established but there is a need to standardize CIPN assessment, also considering that health care providers and patients frequently have a different perception of CIPN severity. Neurotoxicity caused by traditional chemotherapy is widely recognized in patients with cancer. The adverse effects of newer therapeutics, such as targeting and immunotherapeutic agents, need more information for the proper management. This review addresses the main neurotoxicities of cancer treatments with a focus on the newer therapeutics. Recognition of these patterns of toxicity is important because drug discontinuation or dose adjustment might prevent further neurological injury. Treatment is symptomatic. For prevention or treatment there is need for further basic research outcomes.]

[Chemotherapy of multiple myeloma]

MIKALA Gábor, CEGLÉDI Andrea, CSACSOVSZKI Ottó, SZEMLAKY Zsuzsanna, PETŐ Mónika

[Multiple myeloma is a multifaceted haematological disease, a plasma cell malignancy that may pose an oncological differential diagnostic challenge. The importance of this disease is emphasized by its incidence. Since there are multiple novel therapies available for myeloma patients, decade-long survival in not uncommon; therefore, myeloma patients provide a signifi cant part of the patients referred to hematological clinics. In this review, fi rst the novel diagnostic criteria are introduced, followed by the standard therapeutic approaches for transplant-eligible and ineligible patients. As the disease nearly always relapses, the later line therapies available in this malignancy are presented with a special emphasis on the Hungarian haematological practice.]

[Clinical role of multigenic prognostic tests in breast cancer therapy]

GYŐRFFY Balázs

[Current clinical practice for breast cancer originates in “evidence based medicine”. In this, each tumor receives a therapy optimal for a given patient population - which might not be optimal for each individual patient. Multigenic tests determining expression of a set of genes can provide additional support in this decision process. Two such tests (MammaPrint and Prosigna) have already received FDA clearance. A number of additional test are commercially available (IHC4, Oncotype DX, EndoPredict, BCI). A common property of these assays is their utility in estrogen receptor positive early breast cancer. The main clinical problem answered by them is the necessity of adjuvant chemotherapy. To date, no reliable algorithm has been identifi ed capable to pinpoint the most effective chemotherapy combination for a given patient. Furthermore, there is no trustworthy test for triple negative breast cancer. The assays utilize different technologies (immunohistochemistry, gene chips, RT-PCR) and a discrepant list of genes - these result in discordance of the predictions for the individual patient. Despite these shortcomings, multigenic tests quickly gained foothold in breast cancer therapy decision process. Their utility is supported by the cost reduction for the health care providers by lowering the number of patients eligible for chemotherapy.]
