[Side-effects are critical challenges in cancer therapy. These complications can threaten the quality of life, sometimes the life itself. One of the most frequent side effects is mucositis, the damage of mucosa, either in the oral cavity (oral mucositis, OM), or in the gastrointestinal tract (gastrointestinal mucositis, GIM). Prevention is a key action for the effi cient supportation. Recognition of OM is relative easy, but of GIM is rather diffi cult. The risk factors could come from the patients and/or can be caused by the therapy. The successful management of mucositis mostly depends on the cooperation of the patient, which is highly infl uenced by the success of care (e.g. decreasing the level of pain). In general, mucositis (especially oral mucositis) a well managable disease, burt more informations are required to increase the quality of prevention and therapy. Such expectation could be realized by specifi c and sensitive biomarkers, however, they are still missing]

[Treatment of testicular germ cell tumors – an up-date]

BAKI Márta

[The frequency of germ cell tumors is about 1% of all male cancers. The incidence increases in developed countries. The prevalence is the highest among the young males. The histologic type, extent of disease and therapy is based on international guidelines. The surgery, radio- and chemotherapy can achieve cure in the germ cell cancer patients. Regarding the late toxicity, the minimal invasive tumors are suggested to keep on the wait and see policy. The complex therapy of poor risk groups reached more than 80% permanent remission rate. The chemotherapy is based on cisplatin, but in second and third line therapy paclitaxel, gemcitabin and oxaliplatin is widely used. After the cure of germ cell cancer patients the careful follow up is mandatory.]

[Angiogenesis – antiangiogenesis]


[Tumor growth requires vascularization to be supplied by oxygen and nutritients. The vascular network could be different between tumors, even during the development of the same tumor (local and systemic spreading), from the occupation of already present vessels to the real angiogenesis (i.e, proliferation of endothelial cells). Moreover, the tumor cells can create channels, mimicking the normal vessels. This spectrum in morphology should be refl ected in the therapeutic response, in the effectiveness of antiangiogens, but the how is unknown. It is sure that acceptable clinical activity can be achieved only with combinations, both with traditional cytotoxic and targeting drugs. The clinical advantage can be hampered by increased toxicity, demanding supportive actions. One of the key decisions is to select the proper therapy considering the patient and the tumor characteristics (today increasingly at molecular level) and predict the response to the therapy. Such (bio)markers are still missing, although intensive research trying the best. Since the main target of antiangiogenic drugs (today and tomorrow) the VEGF/R family, a useful marker is expected from them. The inhibition of angiogenesis is a logical step against the solid tumors and these steps slowly but steadily can improve the patients life-time, as well as their quality of life.]

[Ablation of liver cancer]

DOROS Attila

[Ablative therapies of the malignant liver tumors are used frequently all over the world. It is a very well tolareted minimally invasive treatment, followed by a short observation period. Patients might be sent home within 24 hours. Nowadays, there is suffi cient data supporting its effectiveness in the treatment of early primary liver cancer, equalling the results of surgical resection. The situation is different in liver metastasis, especially from coloectal cancer. In these cases ablative techniques have a supporting role, limiting their action on the multimorbid patients and small non-resectable tumors. These facts and trends - worldwide and in Hungary - are discussed, focusing on effectiveness, places in therapeutic protocols and domestic diffi culties.]

[New challenges and possibilities in the chemotherapy of small cell lung cancer]


[The small cell lung cancer is characterized as a rapidly proliferating systemic neoplasm, where the basic treatment modality is the chemotherapy . Even in the surgically treated cases the platina based chemotherapy combination is obligatory before and after the surgical resection, combined with preventiv cranial irradiation to minimize the risk of the cranial metastases. The platina based chemo-radiotherapy is the gold standard in the locally advanced cases. Palliativ local irradiation could be useful for pain relief or decompression in the metastatic cases. Prophylactic cranial irradiation strongly recommended in any cases. There are no newly developed drugs for the treatment of SCLC, however it is a chemosensitive carcinoma. Topotecan could be effective in second or third line therapy , especially in brain metastasis.]

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias


In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

BOCZÁN Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette, SZÉLL Márta, KARCAGI Veronika, ZÁDORI Dénes, MOLNÁR Mária Judit

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]

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


[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]


[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.]

[Hypertension, COPD and COVID-19. Focus on antihypertensive therapy]


[Chronic obstructive pulmonary disease is a very common comorbidity of hypertension and it is often unrecognised by physicians. The factors involved in the pathomechanism of both diseases should be realised when choosing treatment. Among factors, hypoxia, increased tone of sympathetic nervous system and activation of renin-angiotensin-aldosterone system should primarily be considered. Vascular wall damage and endothelial dysfunction has an important role in both conditions. The goals of treatment are elimination of risk factors, optimizing the blood pressure, the consequential prevention of cardio-cerebrovascular, renal and pulmonary damage; finally prolonging the patients’ life and improving their quality of life as well. Both hypertension and COPD significantly worsen the condition of COVID-19 patients since they increase the severity of the disease and the rate of in-patients’ and their mortality. In the treatment of hypertension among COPD and COVID-19 patients there must be emphasized the medication inhibiting of renin-angiotensin-aldosterone system, such as angiotensin-converting en­zyme inhibitors or angiotensin-II AT1 re­cep­tor antagonists. Special attention concerned the beneficial effect of mineralocorticoid receptor antagonist spironolactone. Other antihypertensive drugs (calcium channel blockers, thiazide-like diu­retics, high selectivity β1 receptor antagonists) may supplement the treatment if necessary. Long-acting β2 receptor agonists, muscarinic receptor antagonists and inhalation corticosteroids may be administered in double or triple combination also in hypertension and COPD as well. It is important to note, that statin therapy and also vitamin D3 improve the condition of COVID-19 patients.]
