[The growth of new blood vessels, angiogenesis is important for tumour progression and metastasis. Vascular endothelial growth factor (VEGF) plays multiple roles in cancer development. Due to it the VEGF seems to be an optimal therapeutic target in breast cancer therapy. The plasma level of this growth factor is highest early in disease suggests that anti-VEGF agents may provide their greatest benefit in firts-line chemotherapy with metastatic breast cancer (MBC). A phase III trial, E2100 evaluated weekly paclitaxel with or without bevacizumab (Avastin), the specific humanised anti-VEGF monoclonal antibody in patients with previously untreated locally recurrent or MBC, doubling of progressionfree survival for all patient subgroups. Bevacizumab is generally well tolerated. The most common adverse events observed in trials hypertension, proteinuria, and wound-healing complications, most of which are grade 1-2 in severity. The registration of bevacizumab for MBC therapy brings new hope for patients. Novel approach of bevacizumab for MBC would be combination chemotherapy and different targeted therapies. Phase III clinical trials of bevacizumab are ongoing in different stages in different settings.]

TELEKES András

[The hydromorphone is a potent semisynthetic opioid agonist which is available in several forms including injection immediately release or retard tablets. Its analgesic efficacy surpasses morphine. The absorption of oral osmotic retard tablet is independent from food- or alcoholconsumption providing steady plasma concentration by once daily application. The clinical pharmacology of hydromorphone is summarized.]

[The effect of bevacizumab monotherapy on progression free survival in recurrent glioblastoma]

CZIGLÉCZKI Gábor, SINKÓ Dániel, BENKŐ Zsolt, BAGÓ Attila, FEDORCSÁK Imre, SIPOS László

[Introduction, the aim of study - Glioblastoma, WHO grade IV is the most frequent primary malignant brain tumor in adults. There are few articles and result about the efficacy of bevacizumab monotherapy. The aim of our paper is to examine the effect of bevacizumab therapy on progression free and overall survival in an extended database of recurrent glioblastoma patients. Patients and methods - In our retrospective study, patients with recurrent glioblastoma treated with bevacizumab had been collected. All of our patients received first line chemo-irradiation according the Stupp protocol treatment. The histological diagnosis was primary or secondary glioblastoma in every patient. The prognostic features of primary and secondary glioblastomas were statistically analyzed. Results - Eighty-six patients were selected into the retrospective analysis. The histological diagnosis was primary glioblastoma in 65 patients (75.6%) and secondary glioblastoma in 21 patients (24.4%). The mean follow up period was 36.5 months. The mean second progression free survival beside bevacizumab therapy was 6.59 months and the mean overall survival was 24.55 months. In secunder glioblastoma cases, the mean second progression free survival was 6.16 months and the mean overall survival was 91.94 months. Conclusion - The bevacizumab therapy is a safe option in recurrent glioblastoma patients. Bevacizumab therapy has a positive effect both on progression free and overall survival and our results confirm the findings in the literature. There is no statistically significant difference in the second progression free survival between glioblastoma subtypes.]

[Experience with bevacizumab in non-small cell lung cancer]

TAMÁSI Lilla, AGÓCS László, MAGYAR Pál

[INTRODUCTION - Bevacizumab, a recombinant anti-vascular endothelial growth factor antibody, is the antiangiogenic drug used at advanced stage of non-small cell lung cancer. It is the only antiangiogenic therapy up till know available with reimbursement in Hungary. It is indicated in the first-line, platinum-based treatment of advanced stage non-squamous nonsmall cell lung cancer, and used together with chemotherapy. CASE REPORT - In this case report we present the case of a patient with advanced stage pulmonary adenocarcinoma, with a progressionfree survival of more than one year with bevacizumab- docetaxel-cisplatine therapy. CONCLUSION - Bevacizumab given together with combination chemotherapy is effective in advanced lung adenocarcinoma.]

A rare entity of acquired idiopathic generalised anhidrosis which has been successfully treated with pulse steroid therapy: Does the histopathology predict the treatment response?

ÖKTEM Özdemir Ece, ÇANKAYA Şeyda, UYKUR Burak Abdullah, ERDEN Simsek Nazan, YULUG Burak

Acquired idiopathic generalised anhidrosis is an uncommon sweating disorder characterized by loss of sweating in the absence of any neurologic, metabolic or sweat gland abnormalities. Although some possible immunological and structural mechanisms have been proposed for this rare entity, the definitive pathophysiology is still un­clear. Despite some successfully treated cases with systemic corticosteroid application, the dose and route of steroid application are controversial. Here, we present a 41-year-old man with lack of genera­lised sweating who has been successfully treated with high dose pulse intravenous prednisolone. We have discussed his clinical and histopathological findings as well as the treatment options in view of the current literature.
