[Medical use of marihuana especially in oncology]

VÉGH Éva

[The medical use of marijuana has gained a considerable attention among wide range of cancer patients lately in Hungary. Consequently, oncologist sare facing questions related to cannabinoids more and more in their clinical practice. This article aims to clarify some basic concepts and to give a brief introduction on the current international and national legislation on their accessibility. Numerous publications have dealt with the application of marijuana in various indications. Among the tumour related indications, the concerned studies mainly refer to chemotherapy induced nausea and vomiting, chronic pain, sleep disorders, anorexia and cachexia. The article also to uches upon on knowledge connected to the causal treatment of malignant tumours, which are currently limited to glioblastoma. Information on the carcinogenic potential of cannabis and information on the popularity and attitudes of American oncologists can be found in this article. This paper gives a literature review in the above mentioned themes.]

[Gene-expression profiles in adjuvant treatment of early breast cancer]

PAJKOS Gábor

[Breast cancer is a heterogeneous disease with different subtypes having a distinct biological, molecular, and clinical course. Assessments of standard clinical and pathological features have traditionally been used to determine the use of adjuvant systemic therapy in early-stage breast cancer; however, the ability to identify those who will benefi t from adjuvant chemotherapy remains a challenge, leading to over treatment of some patients. Risk stratifi cation of patients with early stage breast cancer may support adjuvant chemotherapy decision-making. This review details the development and validation of seven multi-gene classifi ers, each of which claims to provide useful prognostic and possibly predictive information for early stage breast cancer patients. A careful assessment is presented of each test’s analytical validity, clinical validity, and clinical utility, as well as the quality of evidence supporting its use.]

[Treatment of head and neck cancer]

KATONA Csilla, LANDHERR László

[Head and neck cancers cause worldwide a signifi cant problem in health care systems. Despite great advances in therapeutic modalities its prognosis has not changed in the past few decades. It is mainly caused by classical risk factors, like alcohol consumption and smoking, but in a signifi cant number of oropharyngeal cancers HPV infection plays a major role, which is associated with a new patient group characterized by a much better prognosis and therapeutic response. In the diagnostic phase staging examinations (CT scan, MRI, FDG-PET) are also involved which are necessary to multidisciplinary decision making. It can be largely infl uenced by the patient’s preference. The therapy is based on multimodality approach; surgery, radiotherapy, chemoirradiation, chemotherapy and the combination of these are used in early or locally advanced tumours. Targeted agents like EGFR inhibitors are partly used in the recurrent/metastatic setting or in combination with radiotherapy. Immun checkpoint inhibitors are new therapeutic options for pretreated, recurrent/metastatic patients and their role is under investigation in earlier therapeutic lines. Several clinical trials aim treatment desintensifi cation strategies in HPV positive tumours. Molecular genetic tests try to defi ne subgroups of patients to plan individualized treatment. Regarding the signifi cant functional and aesthetic damage of both disease and treatment, supportive care and rehabilitation are of great importance.]

[PI3K–AKT–mTOR pathway as a therapeutic target]

KOPPER László

[The PI3K-AKT-mTOR is one of the most busy signalling pathway, accepting and sending the message to the effector compartment. The pathway is very complex with activators (see the name), and inhibitors, as PTEN. Depending of the cell type this pathway participates in almost all functions of a given cell. The members of the pathway may have genetic failures, as a consequence, the risk for the development of different diseases, including cancer is high. Therefore it is logical to produce drugs to inhibit the dysregulated function. Unfortunately, despite the promising preclinical effectivity, so far only 4 drugs can be used to treat cancer patients. There are some hypothesis for the in effectivity, e.g. no useful marker for patient selection, high toxicity, false drivers for targeting. What is sure, combination therapy is much better than monotherapy]

[Earlier and more efficiently: the role of deep brain stimulation for parkinson’s disease preserving the working capabilities]

DELI Gabriella, BALÁS István, KOMOLY Sámuel, DÓCZI Tamás, JANSZKY József, ASCHERMANN Zsuzsanna, NAGY Ferenc, BOSNYÁK Edit, KOVÁCS Norbert

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]

[The efficacy of ibandronate and the importance of adherence - Results of the BOUNCE study]

DONÁTH Judit, POÓR Gyula

[Bisphosphonates play a substantial role inthe treatment of postmenopausal osteo-porosis. Ibandronate is the first bisphos-phonate that can be used both orally andintravenously. A number of studies haveproved that ibandronate reduces boneturnover, increases bone mineral densityand reduces the risk of vertebral fractures.It is a well-known fact that the patients’adherence to oral medications is very poorthroughout the world. So far, very fewinternational studies have been performedon the patients’ compliance in medicinetaking. The BOUNCE study, carried out inseveral countries including Hungary tostudy the adherence of patients in the oralintake of ibandronate, aims to fill this gap.]

[Radiosurgery of intracerebral cavernomas - Current international trends]

NAGY Gábor, KEMENY A. Andras, MAJOR Ottó, ERÕSS Loránd, VÁRADY Péter, MEZEY Géza, FEDORCSÁK Imre, BOGNÁR László

[Although still a controversial management option, radiosurgery of intracranial cavernomas has become increasingly popular world-wide during the last decade. Microsurgery is a safe and effective treatment for symptomatic hemispheric cavernomas. However, the indication for microsurgical resection of deep eloquent cavernomas is relatively limited even in experienced hands. The importance of radiosurgery has recently been appreciated in parallel with increasing positive experiences both in terms of effectiveness and safety, especially for cases high risk for surgical resection, in the brainstem, thalamus and basal ganglia. While radiosurgery was earlier indicated mainly for surgically inaccessible lesions that had bled multiple times, a more proactive policy has recently become more accepted. In our opinion preventive treatment with the low morbidity radiosurgery serves the patients’ interest especially for deep eloquent lesions that had bled not more than once, due to the cumulative morbidity of repeated hemorrhages. Despite our increasing knowledge on natural history, there is currently no available treatment algorithm for cavernomas. Arguments for all three treatment modalities (observation, microsurgery and radiosurgery) are established, but their indication criteria are yet to be defined. It is time to organize a prospective population based data collection in Hungary, which appears to be the most realistic way to clarify indication criteria.]
