[Covid-19 associated neurological disorders]

SZÔTS Mónika, PÉTERFI Anna, GERÖLY Júlia, NAGY Ferenc

[The clinical signs of SARS-CoV-2 infection has become more recognisable in recent times. In addition to common symptoms such as fever, cough, dyspnea, pneumonia and ageusia, less common complications can be identified, including many neurological manifestations. In this paper, we discuss three Covid-19 associated neurological disorders (Case 1: Covid-19 encephalitis, Case 2: Covid-19 organic headache, Case 3: SARS-CoV-2-infection and ischaemic stroke). We emphasize in our multiple case study that during the present pandemic, it is especially important for neurologists to be aware of the nervous system complications of the virus infection, thus saving unnecessary examinations and reducing the frequency of patients’ contact with health care personnel. ]

[Despite the modern invasive acute cardiac care available for all, as opposed to short-term mortality, the long-term mortality of Hungarian myocardial infarction patients exceeds significantly those of European patients getting similar treatment. In order to change this situation, it is necessary to assess and analyse exactly the factors behind. While analysing retrospectively the data of Hungarian acute myocardial infarction patients, we identified the influencing factors of short- and long-term mortality. This study processed data from 2003 to the present days from a number of registries (Heart- and Vascular Center of Semmelweis University VMAJOR I and VMAJOR II registry, Stent for Life I and II Programs of the European Society of Cardiology, National Public Health Service’s registry about Cardiac Care in Central Hungary, Budapest Modell database). According to our detailed examination, the proportion of primary per­cutaneous coronary intervention in ST-segment elevation myocardial infarction is at Western-European level, however the invasive treatment of acute coronary attack patients with Non-ST segment myocardial infarction is below the required. The so-cal­led hesitation span of Hungarian pa­tients with ST-segment myocardial infarc­tion is substantially longer than that of neighbouring countries thus the average cardiovascular risk of relevant Hungarian patients is significantly higher than those of the GRACE Register’s population. Based on our results a complex strategy can be developed which may have impact also on strategic health­care decisions in order to reduce the long-term mortality of patients surviving myocardial infarction.]

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]

[Digitally-assisted treatment planning in precision oncology]

PETÁK István, VÁLYI-NAGY István

[The progress of molecular information based on personalized precision medicine has reached a new milestone. Actually, about 6 million mutations of 600 genes may be related to the development of cancer, and on average, 3-4 of these “driver” mutations are present in each patient. Due to the progress in molecular diagnostics, we can now routinely identify the molecular profile of tumors in clinical settings. By clinical translation, there are actually available more than 125 targeted pharmaceuticals and hundreds of such therapies are under clinical trial. As a result, we have many first-line and licenced treatment options to be elected by molecular information as the optimal one for every patient. There is an increasing need for complex informatics solutions by medical software. Geneticists, molecular biologists, molecular pathologists, molecular pharmacologists are already using bioinformatics and interpretation software on their daily work. Today, online digital tools of artificial intelligence are also available for physicians for assisted treatment planning. Telemedicine, videoconferencing provide solutions for interdisciplinary virtual molecular tumor boards, which democratizes the access to precision oncology for all doctors and patients. ]

[The treatment of the locally advanced and the metastatic gastric cancer]

SIPŐCZ István

[Although signifi cant progress has been made in the treatment of stomach cancer recently, survival results are still quite modest. The purpose of this overview is to take a look into the history of the treatment of locally advanced and metastatic stomach cancer and to present the current treatment standards. It focuses on recent changes in perioperative treatment, as well as the changing of treatment of metastatic patients. The use of multiple line of palliative chemotherapy and the place of the available targeted treatments in metastatic tumours will be analysed in detail. The increasing use and the future possibilities of immunocheckpoint inhibitors will also be discussed. Molecular subtypes of gastric cancer are also mentioned as possible indicators of the choice of therapy. Finally, it intends to give therapeutic proposals to make recommendations to treat the disease taking into account the opportunities in Hungary.]

[Treatment sequencing in metastatic colorectal cancer]

MODEST D. P., PANT S., SARTORE-BIANCHI A.

[Metastatic colorectal cancer (mCRC) remains incurable in most cases, but survival has improved with advances in cytotoxic chemotherapy and targeted agents. However, the optimal use and sequencing of these agents across multiple lines of treatment is unclear. Here, we review current treatment approaches and optimal treatment sequencing across the fi rst-, second- and third-line settings in mCRC, including biological aspects affecting sequencing and rechallenge. Effective fi rst-line therapy is a key determinant of treatment outcomes and should be selected after considering both clinical factors and biological markers, notably RAS and BRAF. The second-line regimen choice depends on the systemic therapies given in fi rst-line. Anti-angiogenic agents (e.g. bevacizumab, ramucirumab and afl ibercept) are indicated for most patients, whereas epidermal growth factor receptor (EGFR) inhibitors do not improve survival in the second-line setting. Molecular profi ling is important in thirdline treatment, with options in RAS wild-type patients including EGFR inhibitors (cetuximab or panitumumab), regorafenib and trifl uridine/tipiracil. Immunotherapy with pembrolizumab or nivolumab ± ipilimumab may be considered for patients with high microsatellite instability disease. Targeting HER2/neu amplifi cation shows promise for the subset of CRC tumours displaying this abnormality. Sequencing decisions are complicated by the potential for any treatment break or de-escalation to evoke a distinct clinical progression type. Ongoing trials are investigating the optimal sequencing and timing of therapies for mCRC. Molecular profi ling has established new targets, and increasing knowledge of tumour evolution under drug pressure will possibly impact on sequencing.]

[Opportunities and challenges in online support of cancer patients]

B. PAPP László

[The online support of oncological care may increase patients’ adherence, and by this it can contribute to the effectiveness of treatment, the improvement of quality of life and physician-patient communication as well as to a higher sense of control over the disease. With the online support of supportive care, patients and their relatives can get information on what they can do in order to improve their conditions, how they can recognize side effects and alarming symptoms of complications, what kind of changes they need to make in their lifestyle and how they can reduce the level of distress. Though the positive outcomes are feasible in many cases, quite considerable number of reports in the fi eld do not meet the requirements of evidence. The online support of oncological care may offer considerable opportunities, however, it may further increase inequality: the more educated and well-off patients with higher level of health awareness may benefi t more, meanwhile for the ones at the bottom of digital divide, the disadvantages may increase. The Hungarian internet coverage and accessibility make the broader online support technologically possible, however, its effectiveness may be hindered by the lack of human skills. Therefore, it is a real challenge to establish such platforms that can be used by the broadest spectrum of society, they are comprehensible for patients and their relatives with lower education, but also satisfying for patients and their relatives with higher level of literacy and expectations.]

[Neoadjuvant and palliative drug therapy for bladder cancer]

MARÁZ Anikó

[The survival of patients with muscle-invasive localized bladder cancer is more favorable if they receive neoadjuvant or adjuvant cisplatin-based chemotherapy before or after cystectomy. Based on the meta-analyses, in case of neoadjuvant cisplatin-based chemotherapy, the 5-year survival benefi t is 5-16%. The outcome is even more favorable in case of patients who respond well to neoadjuvant chemotherapy (pathological complete remission rate 12–50%). More than 3 months delay of cystectomy does not signifi cantly reduce the survival if chemotherapy is performed before the operation. Results of adjuvant phase III studies and meta-analyses are not so unambiguous as neoadjuvant data, but chemotherapy seems to infl uence favorably PD-L1 expression the survival, especially in case of pT3/4 and/or N+ (and high grade or margin positivity) cases. According to the recent publications, outcome data of patients have been effective in case of progression after platinum therapy, in or after second-line and in fi rst-line therapies for cisplatin ineligible, PD-L1 positive patients, respectively. Survival and tumor response data are very promising; in particular stages, they seem to be more effective than the previously administered chemotherapies. Current and ongoing trials are investigating the combinations of new remedies with other immunotherapeutic agents or chemotherapies as well as trying to identify biomarkers in order to further increase effectiveness.]

[Treatment of cholangiocellular carcinoma]

ANDRÁS Csilla, ÁRKOSY Péter

[Tumors of the biliary tract are a rare entity, at the time of diagnosis most of the patients are in advanced stage and operation can’t be effectuated. After operation the risk of recurrence is high. The standard adjuvant therapy is capecitabin based on the results of BILCAP study. In advanced stage or in the presence of metastates the standard fi rst line treatment is gemcitabine and cisplatin therapy, there are noninferiority results from a Japan study with gemcitabin and S1 combination therapy. There was no evidence of second line treatment possibilities after gemcitabine and cisplatin therapy until 2019, but based on the results of ABC-06 study mFOLFOX could be the choice in the future. In the case of MSI-H/dMMR tumors immuntherapy should be considered. Personalised medicine with matched molecular targeted therapy is a new option. There are 2 new molecular targets, FGFR and IDH, the preliminary result are very promising.]

[Systemic anticancer therapy in patients undergoing hemodialysis]

VÉGH Éva, LAKATOS Gábor, TOKODI Zsófia

[The number of cancer patients receiving regular dialysis treatment is increasing. These patients could benefi t similarly from the regular anticancer therapies. Data of the use of antineoplastic therapies in this vulnerable patient population mainly come from case reports and small case series. The lack of knowledge and lack of practical experiences in this patient group may lead to suboptimal cancer treatment. Defi ning the indication for antineoplastic treatment and choosing the appropriate drug is a challenging task and the patients’ prognosis and quality of life aspects should be evaluated carefully. The timing of anticancer treatment and the dialysis is also an important issue in this decision-making process. Close cooperation between the oncologists and nephrologists is essential in the proper antineoplastic treatment of the dialysed patients.]
