[Non-surgical treatment of ovarian cancer]

PIKÓ Béla, LACZÓ Ibolya,, MARIK László

[The primary surgery with an optimal cytoreduction is an essential step during the treatment of the epithelial ovarian cancer because it determines the effectiveness of other therapeutic options as well. Immediately after the surgery a cytostatic infusion typically 40-42.5 degrees Celsius is pumped directly to the abdomen. During the systemic therapy the main point is the 6 months progression free survival because beyond this time the disease could be considered as platinum sensitive, inside this time as platinum refracter or resistant disease. The cytostatic treatment improved during the years from the alkylating agents through the platinum derivates to the administration of paclitaxel with several combinations of them and with more and more signifi cant results and less side effects. The most signifi cant targeted agents are the angiogenesis inhibitors (mainly the bevacizumab) and the PARP-inhibitors which prevents DNA repairs. In order to a PARP-inhibitor could be administered a platinum sensitivity is required while BRCA mutation not. Recently there are promising clinical researches with immunotherapy as well. The main benefi t of the hormonal therapy is the tolerability. Besides the signifi cant improvement in the systemic agents the role of radiotherapy is more and more decreasing, however the treatment of the whole peritoneal surface – mainly with the modern radiation techniques – could be an alternative solution for the chemotherapy. The palliative irradiation which relieve the symptoms could extend the drug-free period and the combination of radiation and chemotherapy could provide further possibilities.]

[Hypertension and Covid-19 - part II.]


[The authors review those components and mechanisms in the two major regulatory systems of circulation and inflammation-coagulation whose internal balance and interactions are pathologically altered during SARS-CoV-2 infection, thereby enhancing lung and systemic inflammation threatening to enter into severe clinical condition. They examine the question of how – in addition to potentially promoting the coronavirus cellular entry and penetration – the RAS inhibitor therapy affects these changes and whether can be supposed difference between the anti-/pro-inflammatory influence of ACEi and ARB treatment of old hypertensive patients representing a remarkably high proportion of victims in COVID-19 epidemic. The paper is focussing to the pathomechanical background of inflammation beyond the direct immunological response to the infection: to the significance of immunological alterations characterizing old hypertensive patients also in basic condition, and to the key components as angiotensin II, ACE2, angiotensin1-7, bradykinin, ARB and ACEi. In conclusion a consideration on optimal point of action is offered in RASi treated and SARS-CoV-2 infected (old) hypertensive patients.]

[What is worth to know about COVID-19 for (not only) a cardiologist]

HEPP Tamás, CSÉKE Balázs, BENCZÚR Béla

[SARS-CoV-2 virus infection sprang from Wuhan the capital of the Chinese Hubei province, at the end of 2019 and caused a worldwide pandemic with 1.5 million confirmed cases and claimed almost 100 000 victims until the beginning of April, 2020. First analyses of Chinese COVID-patients confirmed that diabetes, hypertension, and cardiovascular diseases were highly prevalent among SARS-CoV2 infected patients, and might be associated with poor outcome. As previously shown for SARS-CoV-1, SARS-CoV-2 similarly utilizes ACE2 as receptor for viral alveolar cell entry. A suspicion has arisen that the widely used ACE-inhibitor/ARB therapy could be potentially harmful for patients suffering from COVID-19 infection as these agents upregulate the ACE2-expressions. From the other point RAAS-blockade might be beneficial due to fact that ACE2 counters the deleterious effects of Angiotensin II. Authors provide a comprehensive over­view of the most recent literature and summarize the link between COVID-19 and car­diovascular disease. It is important to em­phasize that there are no available hu­man evidences confirming if the RAAS-in­hi­bitor therapy were harmful or helpful in pa­tients suffering from COVID-19.]

[Recommendations of the European Atherosclerosis Society (EAS) and the European Society of Cardiology (ESC) for dyslipidaemia. Focused on: primary prevention]


[In 2019 the European Atherosclerosis So­ciety (EAS) and European Society of Car­dio­logy (ESC) renewed their dyslipidae­mia guidelines. The new version is more progressive than the previous ones. Thus, in the low-risk, not severely hy­per­choles­te­ro­lae­mic population cholesterol-lowering medication is also suggested. Except this low-risk group, atherogenic target values, e.g. for LDL-cholesterol, were reduced by an entire category, in some cases to the lowest one. If these goals cannot be achieved with statin-monotherapy, combined treatment is recommended generally by the cholesterol inhibitor ezetimib, and in some very high-risk cases also by innovative cholesterol lowering so-called PCSK9 inhibitor. ]

[CDK 4/6 Inhibitors in Breast Cancer: Current Controversies and Future Directions]


[Purpose of review: To describe the clinical role of CDK 4/6 inhibitors in hormone receptor-positive (HR+) metastatic breast cancer (HR+MBC) as well as current controversies and evolving areas of research. Recent fi ndings: Palbociclib, ribociclib, and abemaciclib are each approved in combination with an aromatase inhibitor or fulvestrant for HR+MBC. Abemaciclib is also approved as monotherapy for pre-treated patients. Key questions in the fi eld include whether all patients with HR+MBC should receive a CDK 4/6 inhibitor up front versus later line, impact on overall survival, role of continued CDK 4/6 blockade, mechanism of clinical resistance, and treatment sequencing. Summary: The development of CDK 4/6 inhibitors has changed the therapeutic management of HR+MBC. Additional research is needed to determine optimal treatment sequencing, understand mechanisms governing resistance, and develop novel therapeutic strategies to circumvent or overcome clinical resistance and further improve the outcomes of patients with MBC.]

[New perspectives in the treatment of lung cancer]

SZONDY Klára, BOGOS Krisztina

[In recent years, huge research is going on in the fi eld of oncology and as a result, we can see a signifi cantly longer survival in this area of medicine. Lung cancer, which has been taken places in the back for decades, it has not become a curable disease, but begins to belong to the chronic diseases. As a result of brilliant surgical technics and stereotactic radiotherapy, or as a result of changes in drug treatment, 5-year survival is not uncommon in metastatic lung cancer patients, next to relatively long progression free survive. After the third-generation cytotoxic combinations the added growth inhibition (VEGF inhibitor) maintenance therapy or continuous pemetrexed cytotoxic chemotherapy were resulted in high survival benefi ts. The fi rst real breakthrough, long progression-free survival was achieved by targeted treatment, which proved to be effective with known driver mutations. The other great result, especially in squamous cell carcinoma, was the immunotherapy, the inhibition of immune checkpoints, which effi cacy was confi rmed in adenocarcinoma also. Several studies are going on with adjuvant or neoadjuvant immunotherapy, and combined use of immunotherapy (either in combination with radiotherapy or cytotoxic chemotherapy).]

[Practical use of meta-analyses in predicting disease risk, outcome, and therapy response in breast cancer]

KAHÁN Zsuzsanna, TARI Gergely, ENYEDI Márton, HARACSKA Lajos

[Germinal BRCA status infl uences patient care both in early and advanced/metastatic breast cancer. Ideally, the patient should make the decision on the type of surgery or the avoidance of radiotherapy being aware of the BRCA status; based on the most recent clinical studies, this knowledge may infl uence the type of chemotherapy in the neoadjuvant, adjuvant, or metastatic setting or may raise the use of emerging targeted therapies. DNA-targeting cytostatic agents, mostly platinum agents and PARP inhibitors that act by inducing synthetic lethality, provide specifi c therapies in BRCA-mutant cases. The optimum place and sequence of these specifi c agents in treatment, however, are not known yet. International guidelines promote BRCA testing for the specifi cation of treatment strategy in all HER2-negative advanced/metastatic breast cancer cases (NCCN) or at least in all cases when, based on certain predictors, the presence of mutations is likely (ESMO). Recently, the methods employed for BRCA testing have improved immensely and are widely available through the services of various providers. For the identifi cation of the mutation, sequencing of the whole genes is needed, which can be achieved faster and more cost-effi ciently using next-generation sequencing (NGS) platforms compared to previous methods. It is the responsibility of the physician to consider the possibility of BRCA mutations and to raise the issue of BRCA testing to the patient if the family history, the age, previous malignant disease(s) of the patient, or the cancer features are suggestive of genetic risk.]

[Advancing therapies in metastatic castration-resistant prostate cancer]

GIULIA Baciarello, MARCO Gicci, KARIM Fizazi

[Introduction: Prostate cancer is the second most common cause of cancer world wide and is the most frequently detected cancer in the European Union in men over 50 years of age. Androgen deprivation therapy remains the corner stone of treatment for recurrent or metastatic disease. Unfortunately, nearly all patients will develop resistance to androgen blockade leading to castration-resistant prostate cancer (CRPC). Over the last 10 years, new treatment shaved ramatically improved overall survival of men with mCRPC. Current therapies are basedon AR-axis inhibitors and taxane-based chemotherapies, aswell as radiopharmaceuticals and Sipuleucel T. Areas covered: The authors provide a review of the current fi eld of systemic therapy in metastatic CRPC. This is followed by an in-depth analysis of recent developments in treatment, and the biological rationale behind these therapies. Expert opinion: Since several trials with docetaxel or novel hormonal agents showed improvement in overall survival in metastatic castration-sensitive prostate cancer, aswell as in non-metastatic castrationresistant patients, it is expected that a growing subgroup of patients will be expose dearlierto chemotherapy and to AR targeted agents. It becomes then fundamental to fi nd novel strategies to over come drug resistance and further improve survival.]

[Medical therapy of peripherial artery disease]


[Care of PAD (peripherial arterial disease) is one of the most negligent area of cardiovascular diseases: on one hand patients suffering from PAD are the most uncared, less educated and health-minded population (it’s enough to keep in mind the high rate of smoking and alcohol-abuse among them) in addition the number of angiologists is insufficient for the treatment of PAD. Although detection of PAD would be easy as a widely applicable, cheap screening method, the ankle-brachial index is available which is an obligatory screening investigation in general care. Therapeutic options are better and better since cilostazol was launched we have an evidence-based treatment which can solve the symptoms, slower the progression which is strongly recommended (IA recommendation) in both American and Hungarian guidelines. Cilostazol, a PDE3-inhibitor has complex pharmacological effect but contraindicated in several clinical conditions as pentoxiphylline is not totally excluded from the therapeutic arsenal of PAD. The place of antiplatelet agents is well-defined in the most recent European guidelines in the treatment of PAD. The jumping development of interventional radiology beyond medical therapy contributed a lot to prevent limb amputations in the case of early detection of PAD. ]
