[Stroma was considered for a long time as an innocent bystander without infl uence on the behavior of the cancer tissue. However, this opinion considerably changed in the last twenty years. Increasing evidences have been gathered proving that all components of the stroma is active participant in the development and progression of cancer. Although stroma can exert protective role against the early development of tumors, this changes soon as cancer cells are forcing the stromal components to support their growth. This can be accomplished by the induction of stromal stiffness, production of fuels, citokines, growth factors, new blood vessels for the progression of cancer cells. This recognition lead to the introduction of a new approach, targeting stroma in anticancer therapy. Among those attempt excellent results have been achieved by the immune and antiangiogenesis therapy, but countless other attempts are going on.]

[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).]

[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.]

[Metals and cancer]

VETLÉNYI Enikő, RÁCZ Gergely

[We often tend to forget about our environment when looking for the origin of a disease. Inhaled air, drinking water and food, substances in contact with the skin all have an effect on the human body. Metals are indispensable parts of our everyday lives, their mining, processing and use cause a continuous exposure to them. Metal exert their effects on the body in various ways. Many of them are essential for maintaining homeostasis, but excessive or harmful metal intake can lead to health damage, including tumour formation through multiple attack points. Metals substitute each other during different transport processes and in the structure of proteins, they cause oxidative stress and bind to DNA, thereby damaging it. Applying them appropriately, the proapoptotic effect of the metal compounds is brought to the fore, thus becoming a therapeutic tool for tumours. Nowadays, platinum(II) compounds are widely used as chemotherapeutic agents and there are many ongoing studies to fi nd metal compounds with an ideal therapeutic and side-effect profi le. The aims of this article were to draw the attention to the dangers of metals in relation to cancer and to highlight their diverse application possibilities in current and future cancer therapy and diagnostics.]

[Current views on the male breast cancer]

BAKI Márta

[Breast cancer in men is a rare disease, and accounts for only 1% of all diagnosed breast cancers. Hungarian incidence by available data much higher. The greatest risk factor of male breast cancer the elevated estrogen concentration in the body. Genetic disorders, as a Klinefelter syndrome and estrogen exposures and other metabolic changes might cause the male breast cancer. Symptom duration is longer than female population and the male breast cancers diagnosed in older ages and advanced stages. Frequency of BRCA2 mutation is probably 10% among male patients. The most common type is invasive ductal carcinoma with estrogen and progesterone receptor positivity. Diagnostic, surgical, radiation procedures and chemotherapy probably same as female breast cancer. The guidelines recommend as in adjuvant and curative setting the tamoxifen and other selective estrogen receptor modulators treatment. By large nation based registry the survival rate is different from male and female breast cancers. New biomarkers, genetic changes are under investigation to understand munch better the male breast cancer.]

[Oncological treatment on certain special cases]

FUTÓ Ildikó, HORVÁTH Dorottya Katalin, LANDHERR László

[Even in the absence of clinically signifi cant co-morbidities, cancer care is a major challenge for both patients and healthcare professionals. Routine anticancer treatment may be complicated by special clinical situations such as pregnancy or organ transplantation. The dosage of certain oncotherapy agents may be further affected by impaired renal and hepatic function or diabetes mellitus. These days, given the improved prognosis of cancerous diseases and increased survival, personalized therapy and prevention of long-term side effects is becoming particularly important, especially in the above-mentioned oncological situations. In this summary, we review the anticancer treatments recommended by ESMO in specifi c clinical situations.]

[Extracellular matrix of intracerebral tumors with different invasion activity]


[Objectives - Ineffective surgical and radiotherapy of glioblastoma is mainly due to its intensive infiltrating behavior. Contrarily, brain metastases of anaplastic carcinomas are well-circumscribed intracerebral lesions that can be easily exstirpated in most cases. The molecules of the extracellular matrix (ECM) play a pivotal role in the peritumoral infiltration. In this study the mRNA expression of the ECM components was investigated in two types of intracerebral malignoma with different invasion activity. Our aim was to identify the ECM molecules that are responsible for the different intensity of peritumoral infiltration of tumors from different origin. Methods - The mRNA expression of twenty-three ECM molecules was determined by quantitative reverse transcriptase polymerase chain reaction. Four pieces of glioblastoma and four pieces of intracerebral lung adenocarcinoma metastasis from neurosurgical operation were investigated. Immunohistochemical investigations were performed in case of five molecules. Results - The mRNA expression of nine molecules (brevican, neurocan, neuroglycan-C, syndecan-1,2,4, tenascin-C, versican and matrix-metalloproteinase-[MMP]2) differed significantly by comparison of the two tumor types. By immunohistochemistry, neurocan, syndecan, versican and MMP-2 showed alteration in staining intensity according to the mRNA expression, while MMP-9 showed higher staining intensity in the metastatic tumor. Conclusions - The identified molecules can play an important role in the different infiltration activity of tumors from different origin. Thus these ECM-components could serve as targets for anti-invasion therapy in the future.]

[Chronic renal failure is a major health problem, affecting 8 to 16% of the population. Regardless of the etiology the common hallmark of chronic renal failure is inflammation, leading to the activation of renal myofibroblasts. Chronic activation of myofibroblasts lead to abnormal accumulation of extracellular matrix, disruption of the architecture of the kidney and finally to reduced renal function. Although our knowledge is rapidly expanding about the pathomechanism of chronic renal failure, we still have no drug to treat or hinder the progression of the disease. In our present review article, we summarize the role of the cytokines of the IL-10 family in renal scarring.]

Clinical Neuroscience



[Even tough the central nervous system (CNS) of gastropods has long been used as a model for studying different neuronal networks underlying behaviors, there is only little information on the molecular components of the extracellular matrix (ECM) of the nervous tissue. Therefore, the aim of the present study was to identify some of the ECM molecules by acid-base histochemistry. Staining with alcian blue at strong acidic pH, and with acridine orange at different pH and salt concentrations was carried out on cryostat sections taken from CNS preparations of adult specimens of the terrestrial snail, Helix pomatia, and the aquatic species, Lymnaea stagnalis, in order to visualize mild (carboxyl) and strong (sulphate) acidic groups, which are characteristic for different glucosaminoglycans. According to our findings, sulphated proteoglycans were abundant in the periganglionic sheath of both species, and they also occurred in the neuropil of Helix, whereas they were absent in Lymnaea. The interperikaryonal space contained mainly carboxyl residues, which might refer to the presence of hyaluronic acid. It is concluded that the ECM of the snail CNS, similarly to that in vertebrates, is partly composed of polymer macromolecules of different chemical properties. It is suggested that adaptation to environmental conditions and/or altered neuronal plasticity are responsible for the differences found in chemical characters of the ECM molecules between the two snail species.]

[Prognostic significance of invasion in glioblastoma]


[Glioblastoma is the most common malignant CNS tumor, its surgical removal is hindered by the tumors invasive nature, while current anti-tumor therapies show limited effectiveness – mean overall survival is 16-24 months. Some patients show minimal response towards standard oncotherapy, however there are no routinely available prognostic and predictive markers in clinical practice to identify the background of mentioned differences in prognosis. This research aims to identify the prognostic significance of invasion-related extracellular (ECM) components. Patient groups with different prognoses were created (OS: group A <16 months, group B > 16 months), and internationally recognized prognostic markers (IDH1 mutation and MGMT promoter hyper-methylation) were tested in the flash-frozen tumor samples. Furthermore, the mRNA levels of 46 invasion-related ECM molecules were measured. Clinical data of the patients who have been operated on at the University of Debrecen Clinical Center Department of Neurosurgery and treated at the Department of Clinical Oncology showed no significant differences except for survival data (OS and PFS), and reoperation rate. All samples were IDH wild type. MGMT promoter hypermethylation rate showed significant differences (28.6% vs 68.8%). The expressional pattern of the invasion-related ECM molecules, i.e. the invasion spectrum also showed major differences, integrin β2, cadherin-12, FLT4/VEGFR-3 and versican molecules having signficantly different mRNA levels. The accuracy of the inivasion spectrum was tested by statistical classifier, 83.3% of the samples was sorted correctly, PPV was 0.93. The difference found in the reoperation rate when comparing different prognostic groups aligns with literature data. MGMG promoter region methylation data in Hungarian samples has not been published yet, and further confirming current knowledge urges the implementation of MGMT promoter analysis in clinical practice. Studying the invasion spectrum provides extra information on tumors, as a prognostic marker it helps recognizing more aggressive tumors, and calls attention to the necessity of using anti-invasive agents in GBM therapies in the future.]
